first_imgReviewed by James Ives, M.Psych. (Editor)Sep 27 2018Severe weather events, such as summer hurricanes, tornadoes, and winter snow storms often result in widespread and prolonged power outages, interrupting essential household functions, including home heating. Power losses may also compromise food storage and home cooling devices. In such a scenario, people may turn to dangerous remedies to compensate for lost electrical power.An editorial article in the October issue of the American Journal of Public Health addresses the threat of carbon monoxide (CO) poisoning.”Unfortunately, poison control centers continue to see surges in generator-associated carbon monoxide poisonings during and after major storms, despite mandated warning labels and public health advisories,” said the article’s author, Fred Henretig, MD, emergency medicine physician and toxicologist at the Poison Control Center at Children’s Hospital of Philadelphia. “In many instances of CO poisoning, tragedies result – whole families are poisoned, some fatally.”Related StoriesResearch sheds light on sun-induced DNA damage and repairPuzzling paralysis affecting healthy children warns CDCResearchers identify gene mutations linked to leukemia in children with Down’s syndromeCO is often called the “silent killer” because it is an odorless, tasteless, colorless toxic gas. CO is made when any appliance that burns wood or fuel (oil, gas, propane, kerosene, coal) is malfunctioning or poorly vented. Early symptoms of CO poisoning are often mistaken for those of the flu and include headache, nausea, sleepiness, dizziness, and confusion. In severe cases CO can cause coma, heart attack, and death. Be suspicious that symptoms may be from CO if they occur shortly after using a furnace or generator, if multiple family members become sick at the same time, or if symptoms improve when outside of a home or building. Babies, children and older adults are particularly susceptible to CO poisoning.”At toxic levels, CO is a frequent cause of poisoning morbidity and death in the U.S., resulting in more that 50,000 emergency room visits each year,” added Henretig.There are ways to make sure that CO does not cause problems in the home: a)Make sure that all furnaces, chimneys, wood stoves, and heaters are checked regularly and are in good condition. b)Never use barbecue grills or gasoline-powered equipment indoors or in a garage. c)During power outages, gasoline-powered generators should only be used outdoors, away from vents or windows, and at least 25 feet from the house. d)Don’t use gas ovens to heat the home. e)Be careful to avoid sitting in a car with the engine running if deep snow or mud is blocking the exhaust pipe. f)Install CO monitors in your home and make sure all monitors have fresh, working batteries. If you think CO is in your home, you may attempt to air out the house, shut off the heating system, and call 911 or your heating company. If you have any symptoms and you suspect CO poisoning, leave the area immediately and contact The Poison Control Center or 911.center_img Source:https://www.chop.edu/last_img read more

(Editor)Dec 18 2018Skin vaccination using a microneedle patch that contains the inactivated respiratory syncytial virus (RSV) and a compound that stimulates immune responses to the virus has been found to enhance protection against this serious disease and reduce inflammation in the body after exposure to the virus, according to a study led by Georgia State University.The findings, published in the journal PLOS ONE, describe a promising, effective RSV vaccine and delivery method, which was tested in mice. There are no approved vaccines to protect against this disease.RSV is a common respiratory disease, but it can be serious for young children, patients with compromised immune systems and elderly people. For children under 1 year old in the United States, RSV is the most common cause of bronchiolitis, inflammation of the small airways in the lung and pneumonia, infection of the lungs.Related StoriesScripps CHAVD wins $129 million NIH grant to advance new HIV vaccine approachNew shingles vaccine reduces outbreaks of painful rash among stem cell transplant patientsUM scientists receive $3.3 million NIH contract to develop opioid addiction vaccineEach year in the U.S., the disease is responsible for 57,527 hospitalizations among children younger than 5 years old, 177,000 hospitalizations among adults older than 65 years old and 14,000 deaths among adults older than 65 years old, according to the Centers for Disease Control and Prevention. There is no licensed vaccine for RSV. In the 1960s, a formalin-inactivated respiratory syncytial virus (FI-RSV) vaccine, delivered intramuscularly (injected into muscle) and tested in clinical trials, had the opposite desired effect and enhanced the disease in children after they were exposed to the virus.In this study, the researchers tested microneedle patch delivery of the FI-RSV vaccine with and without an adjuvant, a substance that enhances the body’s immune response to foreign particles, called monophosphoryl lipid A. To compare efficacy to the microneedle patch, they also delivered the FI-RSV vaccine intramuscularly. The studies were conducted in mice. The microneedle patch was developed by Dr. Mark Prausnitz of the Georgia Institute of Technology.Microneedle patches contain small needles measuring one millionth of a meter that are coated with vaccines in dry formulation. They can be applied to the skin as a patch and administered simply and painlessly. This technique of delivering vaccines to the skin could be ideal for children who are afraid of needles and more effective in preventing RSV vaccine-enhanced disease. Studies have found that microneedle patch vaccination can result in stronger, wider and longer-lasting immune responses than intramuscular vaccination. The addition of the adjuvant to the microneedle patch significantly increased the vaccine’s ability to induce an immune response, clear the virus from the lungs of mice and prevent RSV inflammatory disease.”Skin delivery of RSV vaccines with an appropriate adjuvant can be translational to the clinic,” said Dr. Sang-Moo Kang, senior author of the study and professor in the Institute for Biomedical Sciences at Georgia State.

Sponsored Content by Alzheimer International SocietyJan 3 2019 insights from industryDr. Lloyd TranDrug Developer & ChairmanNeuroActiva, Inc.An interview with Dr. Lloyd Tran from NeuroActiva, discussing the major barriers to Alzheimer’s research and development over the past 40 years, and how the IUFAA are working to overcome these challenges.Why have so many Alzheimer’s drugs failed in the past 40 years?It has now been 112 years since Dr. Alois Alzheimer first discovered amyloid plaques in the brain of Auguste Deter during an autopsy, and we still don’t have a treatment. Currently, there are several drugs on the market, but these are classed as symptom-modifying drugs, which cannot alter the course of the disease and are only effective for 3-6 months. Alzheimer Society International Congress (ASIC 2019) NeuroActiva, Inc. Together, we decide on the theme of the Congress and the speakers we’d like to invite. This year, we will be focusing on what we have learned over the past 40 years in Alzheimer’s drug failure and research; where we are now, where are we heading to, and the strategies that we need to develop to conquer the disease.What does the next decade look like for Alzheimer’s research and development?I think the next decade will be much more productive, much more focused, and within the next seven years, we will get a new treatment approved for Alzheimer’s disease.I expect to see a lot of development in emerging fields such as neurogenetics and biomarkers, which will be used to develop new diagnostic tools that require a blood test rather than a CSF sample or PET scan, which are highly invasive.We may also develop new informatics tools, deep data learning, and artificial intelligence that can be used by our clinicians to accelerate the use of treatments and diagnostics.Hopefully, over the next 10 years, we will come up with a certain prevention method that would help many people, particularly to a population group that is at risk for Alzheimer’s disease. We hope to not only conquer the disease, but also be able to prevent, mitigate, and improve patients’ quality of life.Where can readers find more information? Register for this year’s event:Alzheimer Society International Congress 2019 Adike | ShutterstockThere’s a real need for a disease-modifying or therapeutic drug that can go to the heart of the problem, treat the patients, and help to prevent or kill the disease.The reason we call it 40 years, despite Alzheimer’s being first reported 112 years ago, is because it wasn’t until 1978 that the United States’ National Institute of Health (NIH) began funding research into Alzheimer’s disease.Back in the early 1970s, Alzheimer’s disease was considered a hopeless and untreatable condition. At that time, many doctors believed that this disease is a disease of aging, and thus, there was no point in researching the condition.There are now several Alzheimer’s hypotheses under consideration. One of the most predominant hypotheses was proposed around 1992. This is called the amyloid cascade hypothesis and is characterized by the buildup of amyloid-beta in the brain, forming plaques. Therefore, a simple way to treat Alzheimer disease is to find a therapeutic drug that can remove, reduce, or mitigate the production of the amyloid beta in the brain.There were other hypotheses, but the amyloid cascade hypothesis was quickly accepted and became the most popular concept in the field. This is why most of the candidate drugs for Alzheimer’s disease focus on the removal of amyloid.Unfortunately, we now know that Alzheimer’s disease is more complex, and can be caused by a number of pathologies, including traumatic brain injury, oxidative stress, diabetics, genetics, and others. To claim that the amyloid protein is the cause of Alzheimer is an oversimplification of the problem.After recognizing the limitation of the amyloid hypothesis, researchers have now begun to look for other causes. Hopefully, from there, we can start to stratify patients and develop better therapeutics.What is the International United Front Against Alzheimer’s (IUFAA) and how is the initiative working to find a cure for Alzheimer’s disease?The International United Front Against Alzheimer is an initiative started by the Alzheimer International Society, with the aim of forming global collaborations between industry and thought leaders in the Alzheimer’s field.One of the main focus points for the IUFAA is accelerating the development of biomarkers to improve diagnostic techniques that help clinician recognize and diagnose patients in the early stage of Alzheimer’s.The Alzheimer International Society has also worked with the International Front Against Alzheimer’s to raise around a billion dollars to fund and accelerate clinical trials. The hope is that we can bring forth a new treatment by 2025. Peshkova | ShutterstockDo you think we are close to developing an effective treatment for this condition?I believe that we are closer than ever to an effective treatment for Alzheimer’s disease. Those 40 years of trial and error have increased our focus and led many pharmaceutical companies to search for the best treatments they can, rather than scatter their efforts in many areas.To give you an idea about the global effort that is going into developing a treatment for Alzheimer’s; according to a publication by Dr. Jeff Cummings, there were 26 new drugs in 35 trials in phase three, and about 63 agents in 75 trials in phase 2 during 2018 alone.Among them, the drugs that target amyloid beta only represent a small part, meaning that the majority of new drugs coming to market are targeting different methodologies, which is a great thing.You are due to attend the Alzheimer Society International Congress in February 2019. Which topics will your talk cover and why?A colleague and I serve as a program coach at the Alzheimer’s Society International Congress with some major industry leaders.last_img read more

(Editor)Mar 8 2019Researchers at the Francis Crick Institute have developed a ‘smart house’ for mice, that allows them to study the animals’ behavior with minimal disturbance for periods of up to 18 months.The ‘Autonomouse’ system improves animal welfare whilst simultaneously enhancing the efficiency and reliability of research findings. The team of scientists and engineers behind it have openly published the design and software of the system in PLOS ONE so that other labs can build their own.Related StoriesResearch on cannabis use in women limited, finds new studyBridging the Gaps to Advance Research in the Cannabis IndustryResearch sheds light on sun-induced DNA damage and repair”We want to understand how the brain works, and for that we need to measure behavior,” explains Andreas Schaefer, Group Leader at the Crick who led the project. “In mice, this is normally done in a very manual and laborious way, which limits the amount of questions we can ask. So we thought of a more efficient way of doing this by getting animals to train themselves.”In Autonomouse, groups of mice live together in an enriched environment with running wheels, ladders and unlimited access to food and water. Each mouse is tagged with a unique microchip – like those used for household pets – so that researchers can carefully monitor its activity levels, weight and water consumption.The microchip also acts as an ID pass to access training: When a mouse enters the training room, a door closes behind it, temporarily preventing other mice from entering while it carries out a learning task for a reward. Data from the learning task is automatically recorded, and linked to the unique mouse ID.”Working with an unstressed, group-housed cohort of mice that train themselves at the time of day that suits them, without the intervention of researchers over long periods of time, makes our experiments better and more efficient,” says Andreas.People from the Crick’s Biological Research Facility, Mechanical Engineering, Electronics and the Making lab, who helped create this system were recently awarded a Crick prize for improving animal welfare.last_img read more

first_img Source:https://www.royalholloway.ac.uk/ Reviewed by James Ives, M.Psych. (Editor)Mar 22 2019New research by academics at Royal Holloway, University of London, urges scientists that are looking to finding a cure for Alzheimer’s disease to focus on the role of proteins in the brain that cause Alzheimer’s disease. This change in focus could enable the development of new treatments.It has long been recognised that genetically inherited (familial) Alzheimer’s disease is caused by mutations in a group of proteins within the human brain known as the gamma secretase complex. The role of these proteins was first identified when mutations in the proteins caused the formation of plaque deposits found in the brains of Alzheimer’s patients, leading to the death of nerve cells in the brain. Scientists have spent many decades analysing this effect without identifying effective treatments.Alternatively, some researchers have suggested that the gamma secretase complex also control a process called autophagy. Autophagy is a process where proteins are broken down into amino acids and reused within the cell, and when autophagy is blocked by mutations in the gamma secretase complex in Alzheimer’s disease, cells in the brain die.New research led by Professor Robin SB Williams and Dr Devdutt Sharma from the Centre for Biomedical Sciences at Royal Holloway, has found that the gamma secretase complex also controls autophagy in a single-celled organism amoeba, known as Dictyostelium, which shared a common ancestor with humans around a billion years ago. The conservation of this role in autophagy for all these years illustrates its critical importance in cell health. This therefore suggests that researchers should look at this process to develop new treatments for Alzheimer’s disease.Related StoriesHealthy lifestyle lowers dementia risk despite genetic predispositionNeural pathways explain the relationship between imagination and willingness to helpNew study reveals ‘clutch’ proteins responsible for putting T cell activation ‘into gear’During this research, Professor Williams and his group used the amoeba, Dictyostelium, as a model to investigate the role of the gamma secretase complex. The group was able to delete individual proteins from the complex, such as the presenilin protein, and monitor changes in cell function. They found that when proteins from the gamma secretase complex were deleted, the process of autophagy was blocked, and so cells were unable to recycle proteins.Professor Williams, said: “These findings suggest that the role of the gamma secretase complex is conserved across a huge evolutionary distance, indicating a fundamentally important role in maintaining healthy cells. From this, we propose that researchers looking to find new approaches to treat patients with Alzheimer’s disease should focus on restoring normal levels of autophagy in neurons of Alzheimer’s disease patients to block the death of brain cells in these patients.”Up until now, there has been very little progress in finding a cure for Alzheimer’s disease. However, if scientists begin to take a different approach to investigating this illness, we may be able to find a way to block the disease. Whilst current medication slows the development of some symptoms, these are not long term solutions, but simply delay the disease progression.”We are hopeful that, using our innovate approach to this research, we will help to refocus researchers in this area, to successfully develop new treatments for patients with Alzheimer’s disease.” last_img read more

first_imgReviewed by Alina Shrourou, B.Sc. (Editor)Apr 27 2019A new study describes trends in filled opioid prescriptions by patient and clinical characteristics for Medicaid-enrolled children. Findings from the study will be presented during the Pediatric Academic Societies (PAS) 2019 Meeting, taking place on April 24 – May 1 in Baltimore.”In this retrospective cohort study of Medicaid-enrolled children and young adults (1 to 21 years old) we found that filled opioid prescriptions are relatively rare (1% of all visits) and adjusted rates decreased from 2012 to 2016,” said Abbey Masonbrink, MD, MPH, a pediatric hospitalist at Children’s Mercy Kansas City and one of the authors of the study. “Providers frequently prescribed opioids combined with non-opioid analgesics and opioids with a black box or safety warning. Future efforts should support development of pediatric pain management guidelines based in a multimodal approach to minimize use of opioids and target reduction of opioids with pediatric safety warnings.”This study involved a retrospective cohort study of children 1 to 21 years old enrolled in Medicaid from 2012-2016 using the IBM Watson Medicaid Marketscan claims database. It defined clinical visits as an “opioid visit” if there was a new opioid prescription filled in a retail pharmacy within seven days of the visit. The opioid visit was then assigned to the clinical provider most likely to have prescribed an opioid. Only visits to providers submitting claims in every year from 2012-2016 were included. Changes in patient and clinical characteristics over time were assessed using descriptive statistics and chi-square tests and logistic regression was used to estimate the change in adjusted probability of an opioid visit over time. Due to the large volume of visits analyzed, p<0.001 was considered statistically significant.Related StoriesRepurposing a heart drug could increase survival rate of children with ependymomaNew therapeutic food boosts key growth-promoting gut microbes in malnourished childrenResearch reveals genetic cause of deadly digestive disease in childrenFrom 2012 to 2016, there were 113,068,027 visits among Medicaid-enrolled children and 1% (n=1,130,006) of these were considered an opioid visit. After adjusting for patient demographics, the researchers found that the adjusted probability for an opioid prescription decreased from 1.2% to 0.8% from 2012 to 2016. The clinical settings with the highest adjusted rates of opioid prescriptions were dental surgery (29%), surgery (21%), and inpatient (upon-discharge) (10%). Furthermore, the adjusted rates of an opioid visit significantly decreased (p<0.001) from 2012-2016 in all settings, except dental surgery and surgery. The most frequently prescribed opioids were hydrocodone (48%), codeine (22%), and oxycodone (14%); most of these prescriptions were in combination with acetaminophen or ibuprofen.Opioid prescriptions filled in Medicaid-enrolled children are relatively rare (1% of all visits), however adjusted rates of opioid visits decreased from 2012 to 2016. Understanding changes in prescriptions over time can inform opioid stewardship efforts to develop clinical guidelines for appropriate pain management in children.Dr. Masonbrink will present findings from "Changes in Opioid Prescriptions for Medicaid-enrolled Children, 2012-2016" on Sunday, April 28 at 8 a.m. EDT.

first_imgBy Dr. Ananya Mandal, MDJul 14 2019A team of Netherlands Institute for Neuroscience researchers have found that a restful night with good REM (Rapid Eye Movement) sleep could counteract the effects of unpleasant experiences and memories. They have found the reason behind such an adaptation. Their study titled, “Restless REM sleep impedes overnight amygdale adaptation,” was published in the latest issue of the journal Current Biology. Image Credit: Eggeegg / Shutterstock The team of researchers conclude that emotional experiences often trigger “amygdala activation.” Unpleasant experiences evoke emotional distress in all individuals. This triggers the circuits of brain mainly in the “limbic system”. Several studies have shown that sleep helps to recover from this distress. Hence, sleep might produce a “time window” for reorganization of these activated circuits.Their study noted that having a night with good amount of REM sleep can help the amygdala adaptation overnight. Having good quality slow wave sleep or NREM sleep preceding the REM sleep also facilitates adaptation of the limbic system. When REM sleep is disturbed or restless, the team writes, there is a failure in amygdala adaptation.The researchers explain that having a restless REM sleep is characteristic of several psychiatric disorders including insomnia and post traumatic stress disorders. This could be, they write, due to “insufficient silencing of the locus coeruleus (LC) during REM sleep.” This insufficient silencing of the LC is responsible for insufficient recovery of the brain after a restful night of sleep. The team wrote that the amygdale is the “siren of the brain”. Its subsequent inhibition during restful REM sleep is responsible for dissolution of distress. This means that the person regains normalcy after an unpleasant experience due to the adaptation of the amygdala.To investigate their hypothesis, the team included 29 participants to study the impact of an unpleasant emotional experience on REM sleep and limbic response using functional magnetic resonance imaging (fMRI). These participants varied in their severity of insomnia. Arousal and pattern of sleep was assessed using electroencephalography (EEG). The purpose was to assess whether the activity of the amygdala was related to restful REM sleep and whether reorganization of amygdala activity was impeded by sleep interruptions.Related StoriesSleep quality linked to memory problems in new studyNovel bed system with VR brainwave-control for sleep blissSleep makes synapses ready for new learningThe team found that the reactivity of the amygdala reduced overnight when there was a decrease in the total REM sleep. They write, “Restless REM sleep impeded overnight amygdala adaptation.”As a next step the team used smells or odours that were tagged to unpleasant emotional experiences. These smells were targeted to trigger the unpleasant memories and reduce the REM sleep. Results showed that good REM indeed was responsible for amygdala adaptation. The team wrote, “a maladaptive type of sleep” could be “target for interventions in mental disorders characterized by restless REM sleep.”For their smell experiment the team used a specific smell along with an upsetting memory. As soon as the participant smelled that odour, he or she showed activity in the brain scans in the region of the amygdala. Then they spent the night sleeping in the sleep labs and an EEG measured their brain waves. Brain waves are typical of different phases of sleep. While sleeping they were again exposed to that smell. Next morning in an awake state the same unpleasant experience was presented again. This time the brain had adapted overnight among those with good REM sleep. This meant that they did not respond to the unpleasant experiences again. Some of the participants were restless sleepers. Among them there was no recovery of the amygdala at night when these people were exposed to the smell and experience again, they experienced distress again. This proved that it was the restful REM sleep that helps the brain circuits to recover overnight.The team wrote that some of the neuronal connections related to a pleasant or unpleasant memory during the day could be strengthened or weakened during the night’s sleep. This was disrupted as well if the sleep was restless.According to study researchers Rick Wassing, Frans Schalkwijk and Eus van Someren, diagnosing restless REM and targeting this phase of the sleep could help patients with insomnia and PTSD and also help them process unpleasant experiences in a better manner.The authors wrote, “REM sleep can support overnight regulation of amygdala reactivity. The effect increases with longer preceding episodes of transition to REM but is impeded by REM sleep interruptions.” They add that people with PTSD or “early childhood adversity” could have chronic restless REM. They conclude, “Addressing overnight emotional memory processing deficits in these disorders is likely to provide clues to the mechanisms underlying hyperarousal, which have so far remained enigmatic.” Journal reference:Restless REM Sleep Impedes Overnight Amygdala Adaptation, Rick Wassing, Oti Lakbila-Kamal, Jennifer R.

first_imgThe first mainstream wearable device with ECG. Credit: Apple Provided by The Conversation Explore further Leaked details of the new iPhone models were quickly relegated to second tier headlines after Apple’s latest product announcement. More people seem to be excited about the fact that the new Apple Watch will come with a built-in heart monitoring electrocardiogram (ECG) function. The physical risks associated with performing ECGs are minimal. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats. It is quick, safe and painless.We shouldn’t ignore concerns that an ECG test in a commercially available watch could encourage many people to make additional trips to the doctor when they have recorded any anomalous activity. A rush of gadget-adorned people descending on clinics demanding services is a worry. But many people already self-diagnose conditions or agonise about symptoms unnecessarily, often caused by using the internet and other technology. Those who do use the Apple Watch ECG may well include large numbers of “worried well”. But the impact of uncontrolled use of ECG technology seems likely to be limited for the moment, especially as many people will still simply be unable to afford it.If ECG is added to the list of readily available health technology applications, it will be little different from enabling people to detect their pulses, count their steps, track their periods and analyse their sleep. An Apple Watch ECG won’t be conducted under controlled conditions, but this is true of so many health consultations.Personal health tech is already commonMedical staff now give out many interventions that can be performed independently at home. This includes some self-tracking technologies and sensitive diagnostic tests, such as those for sexual health and bowel screening. In some places, you can even swap the GP’s surgery for a smartphone app.While accuracy may be an issue with the Apple Watch ECG, the same is true for ECG tests performed in clinics and interpreted by professionals, according to many papers published on this topic. Of course, technologies can always be improved, but waiting until a test is close to perfect isn’t necessarily the best way to use it. Ultimately, we are living in a digital age and healthcare has so far been slow to revolutionise. We should be harnessing technology to improve healthcare. Everyday ECG won’t replace medical care but might help people to spot important warning signs and seek expert opinion. The real-time data the device has already collected may then help inform a medical expert’s interpretation and diagnosis.What we should really be thinking about is how we can widen appropriate access for this kind of technology to those who it would most benefit, so that it might identify more people at risk, earlier. This would help make health services more efficient, reduce waste and perhaps even save lives. Apple’s smartwatch has a heart monitor nowcenter_img This article is republished from The Conversation under a Creative Commons license. Read the original article. An ECG is a simple test that can be used to check your heart’s rhythm and electrical activity, designed to detect any underlying issues. The Apple Watch 4 will be the first mainstream wearable gadget to integrate this kind of medical diagnostic technology. (Other devices such as the Fitbit typically measure blood flow by shining a light through the skin. This should be an exciting breakthrough, but Apple’s revelation has been met with a mixed reception.There isn’t yet enough evidence to show that using an ECG in general to screen people for cardiovascular diseases ultimately makes them healthier. In fact, it’s not recommended for screening people who are at low risk of developing problems because it could produce false positive results (indicating a problem where none really exists). This can then lead healthy people to seek unnecessary, invasive and potentially harmful treatments, at a cost to the health service provider, as well as producing increased anxiety. For those who are at high risk of disease, ECG results might suggest medical intervention when lifestyle changes could actually be more beneficial. But does this really mean the technology shouldn’t be made more widely available?It would be naive to assume that everyone who is at risk of heart problems knows, never mind consults with a doctor, about it. Often, people don’t realise until it is too late and they need emergency treatment and lengthy retrospective investigation – or, at worse, they die. To ignore the current digital health movement, and surging enthusiasm for it among early adopters of devices, health enthusiasts and growing numbers of people more generally would also be foolish. The industry is booming. The growing numbers paying to monitor their health with fitness trackers and smart watches has shown how engaged and motivated people can become. We shouldn’t be denying people opportunities to take greater responsibility for their health, particularly as health services come under growing pressure from an ageing and increasingly ill population.

first_img Provided by The Conversation My colleagues and I instead hope to build the first dedicated neural network computer, using the latest “quantum” technology rather than AI software. By combining these two branches of computing, we hope to produce a breakthrough which leads to AI that operates at unprecedented speed, automatically making very complex decisions in a very short time. We need much more advanced AI if we want it to help us create things like truly autonomous self-driving cars and systems for accurately managing the traffic flow of an entire city in real-time. Many attempts to build this kind of software involve writing code that mimics the way neurons in the human brain work and combining many of these artificial neurons into a network. Each neuron mimics a decision-making process by taking a number of input signals and processing them to give an output corresponding to either “yes” or “no”. Each input is weighted according to how important it is to the decision. For example, for AI that could tell you which restaurant you would most enjoy going to, the quality of the food may be more important than the location of the table that’s available, so would be given more weight in the decision-making process.These weights are adjusted in test runs to improve the performance of the network, effectively training the system to work better. This was how Google’s AlphaGo software learned the complex strategy game Go, playing against a copy of itself until it was ready to beat the human world champion by four games to one. But the performance of the AI software strongly depends on how much input data it can be trained on (in the case of AlphaGo, it was how often it played against itself).Our Quromorphic project aims to radically speed up this process and boost the amount of input data that can be processed by building neural networks that work on the principles of quantum mechanics. These networks will not be coded in software, but directly built in hardware made of superconducting electrical circuits. We expect that this will make it easier to scale them up without errors.

But this approach typically involves building software so information is processed in a similar way to the brain, rather than creating hardware that mimics neurons. Traditional computers store data in units known as bits, which can take one of two states, either 0 or 1. Quantum computers store data in “qubits”, which can take on many different states. Every extra qubit added to the system doubles its computing power. This means that quantum computers can process huge amounts of data in parallel (at the same time).So far, only small quantum computers that demonstrate parts of the technology have been successfully built. Motivated by the prospect of significantly greater processing power, many universities, tech giants and start-up companies are now working on designs. But none have yet reached a stage where they can outperform existing (non-quantum) computers.This is because quantum computers need to be very well isolated from disturbances in their surroundings, which becomes harder and harder as the machines get bigger. For example, quantum processors need to be kept in a vacuum at a very cold temperature (close to absolute zero) otherwise they could be affected by air molecules striking them. But the processor also needs to be connected to the outside world somehow in order to communicate.More room for errorThe technical challenges in our project are very similar to those for building a universal quantum computer that can be used for any application. But we hope that AI applications can tolerate more errors than conventional computing and so the machine won’t need to be quite so well isolated.For example, AI is often used to classify data, such as deciding whether a picture shows a car or a bicycle. It doesn’t need to fully capture every detail of the object to make that decision. So while AI needs high computer speeds it doesn’t demand such high levels of precision. For this reason, we hope that makes AI an ideal field for near-term quantum computing.Our project will involve demonstrating the principles involved with a quantum neural network. To put the technology to its full use will involve creating larger devices, a process that may take ten years or more as many technical details need to be very precisely controlled to avoid computational errors. But once we have shown that quantum neural networks can be more powerful than classical AI software in a real world application, it would very quickly become some of the most important technology out there.last_img read more

first_img Citation: Advancing additive manufacturing by slashing support (2019, February 20) retrieved 17 July 2019 from https://phys.org/news/2019-02-advancing-additive-slashing.html “Traditionally, the support structure is created by simply considering the geometry of the part, and then creating the columns needed for support,” Qian says. “But this isn’t optimized.”His method streamlines the support structure using computational modeling tools. By enabling manufacturers to use the minimum amount of support material, the approach delivers faster build times as well as cost savings on material.Qian’s techniques are broadly applicable for a wide variety of additive manufacturing technologies. So far, he has demonstrated the benefits of his approach using fused deposition modeling and 3-D-printed metal parts using a laser powder bed fusion process. In one project, he used his techniques to design a part that required 43-percent less supporting material than would be used in the traditional additive manufacturing process relying on standard commercial design software. AI technology addresses parts accuracy, a major manufacturing challenge in 3-D printing 3-D printing opens up design possibilities that engineers could once only dream of. Provided by University of Wisconsin-Madison This new approach grew out of Qian’s interest in exploring ways to improve the structural performance and functionality of parts by leveraging the design flexibility additive manufacturing offers. For example, he has designed parts with component shapes and topologies that are optimized to dissipate heat. Such parts would be useful for many applications requiring a heat sink, including in electronics.The logical next step was optimizing the parts’ support structure. “Surprisingly, we didn’t see anyone else trying to use topology optimization to accomplish this,” Qian says.He says a 3-D-printed part generally needs support if there are areas where its surface is sloped facing downward. Explore further Professor Xiaoping Qian has devised a method that significantly reduces the amount of support material needed to build components with 3-D printing.

Credit: Sarah Page The technology allows manufacturers to create parts with unique and complex shapes—parts that conventional manufacturing methods such as die casting or injection molding can’t produce.With 3-D printing, also known as additive manufacturing, a machine creates a part by adding material in layers, building the object from the ground up. Because each new layer needs to be supported by the layer below it, there’s a limit to how much one layer in a complex part can jut out over the next. As a result, manufacturers often need to build structures to support a part as it’s being printed.”But after the part is completed, removing that supporting material can be costly,” says Xiaoping Qian, a mechanical engineering professor at the University of Wisconsin-Madison. “These support structures are sometimes referred to as sacrificial structures, because they are discarded in the end, which wastes material and build time.”Furthermore, it can be difficult to access and remove the support structure without risking damage to the finished part.To address these issues, Qian has devised a method that significantly reduces the amount of support material needed to build components with 3-D printing—and, in some cases, can even eliminate the need for support structures altogether. Qian’s new method reduces the amount of support material (black plastic) needed to allow the red material (Bucky) to be 3D-printed. Credit: Sarah Page However, in the topology optimization process, engineers first provide requirements for the part and overall design goals—and then a computer program performs analyses and generates ideal component topologies.”So the challenge is, if you don’t know the geometry of the part in advance, then how would you know the surface slope and whether you would need support or not?” Qian says.That’s where his breakthrough comes in—in a way that’s somewhat like predicting the future.Qian developed a method for calculating the amount of surface area on a component that needs support—without knowing the part’s final geometry ahead of time. He says the key was defining a new measurement called the projected undercut perimeter. “When you calculate this new measurement, it essentially corresponds to the area that needs support,” he says.By incorporating the new measure into his computer models, Qian is able to control the amount and angle of overhang—thus minimizing or even eliminating the support structure—when designing a part.As a result, for example, he can design a component that’s optimized to dissipate as much heat as possible without needing any support structure to manufacture.Designing such entirely self-supporting parts is an active research area for Qian, and his work is poised to benefit manufacturers looking to not only save money on materials and fabricate parts in less time but also create new types of parts with increased functionality.

first_imgFacebook on Tuesday launched an app that will pay users to share information with the social media giant about which apps they’re using. The company previously rolled out two similar apps that tracked what activities people did on their phones. But both were shut down after drawing criticism for infringing on privacy and violating Apple’s App Store guidelines.Facebook said the new app, called Study, is different than the previous two and was built from scratch. And it is only available on the Google Play Store, though Facebook said it might work to expand it to iOS in the future.The new app will collect information about which apps people are using and for how long, including which app features are used. That could give Facebook valuable insight into how people use its competitors’ services.Facebook said it will not track passwords or account IDs and it will periodically remind people that the app is collecting their data.A previous market-research app from the company, called Research, got in hot water earlier this year when a report found that teens were using it and it was sidestepping Apple’s guidelines. Apple booted it from its app store and Facebook eventually shut it down completely.The other app, called Onavo Protect, was a virtual private network service used to keep information private in public settings—but it was also collecting information about app usage and sending it to Facebook. That app, too, has been shut down.Facebooks appears to be acting in a more upfront manner this time, said Lance Cottrell, chief scientist for the cybersecurity firm Ntrepid.”They are being a little less intrusive with this one,” he said, noting that Facebook says it won’t collect some of the more sensitive information from people’s phones such as photos and web searches.What it will do, Cottrell suspects, is give Facebook further advantage over competitors because it will be able to tell how long apps are being used, and even which features within them are most popular. Facebook already has a step up when setting up such market research, Cottrell said—not many other companies could release a similar service and get as many participants as Facebook is bound to.”It’s a lot of competitive intelligence, but a little less spying on the users,” he said.But some privacy experts are concerned users will still not know exactly what information they are sending.Many people skip reading privacy policies, noted mobile app security researcher Will Strafach, who studied the underlying code of Facebook’s Research app earlier this year. And if Facebook updates the privacy guidelines, there is no guarantee they will be upfront about it, he said.”I think that it’s Facebook’s job to make it extremely clear (how it works),” he said. “They haven’t done that in the past.”In any case, one thing the app is sure to do is give Facebook more insight into personal data and use of not only its own services, but others as well.Facebook said the app will not be used to serve people ads, and information will not be shared with third-party companies—a line the company has been walking carefully since its Cambridge Analytica scandal last year that exposed the data of millions of Facebook users to an outside political research firm.The Study app is now available in the U.S. and India. Facebook is not saying how much it will pay participants to share their information. © 2019 The Associated Press. All rights reserved.

first_img Eight-eyed huntsman spiders in the Sparassidae family deliver venomous bites with their sharp fangs, paralyzing small prey. Credit: Courtesy of Justine Latton Latton’s husband was conducting repair work at the lodge when he noticed the spider lurking on the door just above his co-worker’s head, Latton told “Tasmania Talks.” The two captured the spider in an empty ice-cream container and released the huntsman outside the lodge; the arachnid skedaddled and left its possum meal behind, Latton said. Huntsman spiders are ambush predators, and they use their large and powerful fangs to deliver venomous bites. Spiders are commonly thought to suck the liquids from their prey; in reality, they vomit digestive fluid onto their meals, chew the saturated flesh and then slurp up the dissolved nutrients, Rod Crawford, curatorial associate of arachnids at the Burke Museum in Seattle, wrote on the museum website. Huntsman spiders’ usual prey includes many types of insects, reptiles and even other spiders. But it shouldn’t come as a surprise that small mammals are also occasionally on the menu. Numerous spider species worldwide are known to eat bats, and researchers recently recorded the first evidence of tropical spiders preying on mouse opossums, in the Peruvian Amazon, Live Science previously reported.

Southern Tasmania resident Justine Latton shared her husband’s photos of the gruesome meal on June 14 in the Facebook group Tasmanian Insects and Spiders. He captured the images at a lodge in Tasmania’s Mount Field National Park while doing light repair work, Latton said yesterday (June 18) on the radio program “Tasmania Talks.” Members of the Facebook group identified the arachnid as a huntsman (also known as a giant crab spider); these large, long-legged spiders in the Sparassidae family live all over Australia. In the photo, the huntsman hangs head-down from a door hinge and grips its prey by the neck. The dead marsupial — which appears to be a pygmy possum, according to commenters — dangles limply from the huntsman’s mandibles. [In Photos: A Tarantula-Eat-Snake World]Advertisement The animal commonly known as a possum in North America (actually an “opossum,” which belongs to a different order) can grow to be as big as a cat; were that the case here, the spider would easily be the size of a large dinner plate. But pygmy possums (Cercartetus lepidus) are the smallest possums in the world, measuring about 2 to 3 inches (5 to 7 centimeters) long and weighing about 0.2 ounces (7 grams), according to Tasmania’s Parks and Wildlife Service. On average, a huntsman spider’s leg span can reach up to 6 inches (15 cm), while their bodies measure about 0.7 inches (2 cm) long, the Australian Museum reported.

first_imgHow much does Rahul know, wonders Jaitley Arun Jaitley, Finance Minister PTI economy (general) The state of the economy was the focus of the verbal slugfest between Arun Jaitley and the Congress today with the Union minister saying that abuse is not the answer in political discourse and the opposition party accusing the government of “economic mismanagement”.The barbs flew thick and fast as Jaitley, who attacked Congress president Rahul Gandhi yesterday saying that wisdom has to be acquired through learning and cannot be inherited, telling Congress communications in-charge Randeep Surjewala that he should respond on facts. Surjewala accused the union minister of “economic mismanagement” in the country after Jaitley claimed that India had emerged as the fastest growing economy from being among the ‘fragile five’ during UPA. The Congress leader again hit back, saying exports are in a free fall, the promise of two crore jobs a ‘jumla’, NPAs had soared to ₹10 lakh crore and loots and scams a norm under this government.“This is a political discourse. Abuse is not the answer. Please respond to the facts,” Jaitley told Surjewala on Twitter, a response to yesterday’s attack in which the Congress leader said the union minister was writing “hollow and wasteful” blogs to regain political relevance.“When you abuse and berate the Congress leadership, even Supreme Court and many others by distorting facts, it is ‘political discourse’ for you, but when you are shown the ‘mirror of truth’ with hard facts, you get ‘unnerved’ and call it ‘abuse’? Politics of Convenience?,” Surjewala asked today in response to Jaitley’s comments on the Congress chief. Jaitley hit back, saying, “… surely the journey from India being part of the ‘fragile five’ and ‘policy paralysis’ to the world’s fastest growing economy could not be result of economic mismanagement – Another case of ignorance.” Surjewala responded by saying that growth under Modi government was at a four-year low. “Exports are in free fall, promise of 2 crore jobs is a ‘Jumla’, NPA’s are soaring to ₹10 lakh crore, investment is down, banks are paralysed and ‘loot scams’ a norm, GST flawed, schemes failing! Isn’t this Economic Mismanagement?”Jaitley had started the verbal duel by taking a jibe at Gandhi for his “anti-Narendra Modi tirade” yesterday. “In dynastic parties political positions are heritable. Unfortunately wisdom is not heritable. It has to be acquired through learning,” he said in a post titled “Is Congress Becoming Ideology-less? Is Anti-Modism its only ideology?,” he had said on his Facebook page.

first_imghealthcare policy COMMENT September 26, 2018 tuberculosis SHARE SHARE EMAIL SHAREcenter_img Even as India aims to eliminate tuberculosis by 2025, the quality of TB care and management provided by the urban private healthcare sector was found to be “suboptimal and variable”, according to a study published in PLOS Medicine. The study was part of two Government-run pilot projects in Mumbai and Patna, where the private sector was engaged by local health agencies, RNTCP and partners, Dr Madhukar Pai, Director of the McGill International TB Centre and a joint author of the study, told Business Line. The data reflects the reality during the 2014-15 period when the project was in its early days, he added. Role of private sector“Private practitioners are delivering a wide range of largely inadequate care to these patients,” the study found. Pai along with Ada Kwan, a PhD student at the University of California at Berkeley, Benjamin Daniels and Dr Jishnu Das from the World Bank, and other colleagues utilised 24 standardized patients (SPs) – seemingly healthy actors trained to portray four different tuberculosis case scenarios during unannounced visits – to assess management and quality outcomes of private providers stratified by qualification in Patna and Mumbai, a note on the study explained. The study comes even as heads of State gather in New York on Wednesday at the United Nations General Assembly’s first-ever high-level meeting on TB to accelerate efforts to end TB and reach all affected people with prevention and care. India accounts for a quarter of the world’s estimated 10.4 million new TB cases per year , nearly a third of the 1.7 million annual TB deaths and a third of the estimated 4 million missing patients who are not diagnosed or reported into the national TB programme. And the private health sector provides the bulk of primary care in India , serving as the first point of contact for 50 to 70 per cent of patients with TB symptoms, the note said. They described the private sector to include allopathic doctors with Bachelor of Medicine, Surgery or higher degrees; Ayush practitioners are those with degrees in alternative or traditional medicine such as Ayurveda, Yoga, Unani, Siddha or Homeopathy. Allopathy vs alternative medicine“The Indian government is working hard to engage the private health sector, but little is known about the quality of care they provide,” said Pai, who also a Professor of Epidemiology at McGill University and a Scientist at the Research Institute of the McGill University Health Centre.Giving details on the study, the note said, “A total of 2,652 SP-provider interactions were analysed across 473 Patna providers and 730 Mumbai providers and weighted for city-representative interpretation. Providers correctly managed SP cases according to national and international standards in only 949 interactions…”The study also found that allopathic providers were more likely to correctly manage cases than non-MBBS providers. There was near-zero use of anti-TB drugs among non-MBBS providers. Finally, providers who were presented with more diagnostic information by the patient offered better care, even if it meant referring their patients to the public sector TB program, the note said. “Merely engaging or educating the private sector providers is not enough. We need to work them to improve the quality of TB care they deliver to patients. So, the government should increase its efforts to improve TB care in the private sector,” said Pai.

first_imgRahul was elected unopposed as Congress president on this day. While political analysts will debate in the coming days the reasons for the BJP’s setbacks in three Hindi heartland states, the Congress brain trust has an unambiguous answer — Rahul Gandhi’s newfound campaign energy. Congress president Rahul, once dubbed by critics as a “reluctant politician”, addressed 82 public rallies and seven road shows since October 6, criss-crossing Madhya Pradesh, Rajasthan, Chhattisgarh, Telanagana and Mizoram on an almost daily basis.Rahul Gandhi, during his spirited campaign, raised several issues such as farmers distress, Rafale deal, corruption, and women’s security in all these states. He also raised state-specific issues such as the Vyapam scam in Madhya Pradesh and farmers’ suicides in Rajasthan.His promise of a loan waiver to farmers in the Hindi heartland states seems to have struck a chord with the people in villages.“With sheer grit and determination, against all odds, defying state coercion and intimidation, Rahul Gandhi has scripted an amazing turnaround for the Congress in a short span of one year,” Congress leader Manish Tewari said.Rahul was elected unopposed as Congress president on this day.Moving forward into 2019, the results in the state polls will give him the “moral hue” to be able to negotiate an all pervasive alliance in order to see the back of the BJP, Tewari said.Referring to Gandhi’s energetic campaign, he said it started off with Gujarat last year, and the Congress chief has demonstrated the tenacity to stay the course over the past one year.Several Congress leaders from the Hindi heartland such as Sachin Pilot, Ashok Gehlot and Bhupesh Baghel credited Gandhi’s dynamic campaign as the reason for party’s good showing.“Our leader (Rahul Gandhi) has led the team well through the campaign, and results are coming accordingly. We did things right and Rahul Gandhi is the ‘man of the match’ and the ‘man of the series’,” Congress leader and Punjab minister Navjot Singh Sidhu said.Sanjay K Pandey, a professor at Jawaharlal Nehru University (JNU) and a political commentator, said Gandhi with his campaign energy has “demolished” the perception of being a “reluctant politician“.“This was said about his father also. There is some truth perhaps that Rajiv Gandhi, Sonia Gandhi and Rahul Gandhi had some reluctance (in taking to politics).“He did make some comments which led people to believe that he was not very keen on politics, but now that has changed. Even in earlier elections he has led an energetic campaign, but probably not to this extent,” Pandey said.The Congress is set to wrest Rajasthan and Chattisgarh from the BJP which was trailing marginally in Madhya Pradesh in a cliffhanger while the TRS stormed back to power in Telangana and the MNF dislodged the Congress in Mizoram.

The facility needed about 60-70 tonnes of soil.ISITE’s parent, the U.R. Rao Satellite Centre, or URSC (it was called the ISRO Satellite Centre or ISAC at the time) did buy a small amount of simulated lunar soil from the U.S., but soon decided to find its own solution at a lower cost.M. Annadurai, who as URSC Director oversaw activities related to the Chandrayaan-2 spacecraft until he retired in August 2018, recounts that geologists of various national agencies had found that a few sites near Salem in Tamil Nadu had the ‘anorthosite’ rock that somewhat matches lunar soil in composition and features. The URSC’s lunar soil simulation studies team zeroed in on Sithampoondi and Kunnamalai villages for the soil.It turned out to be a ₹25 crore project: experts from the National Institute of Technology in Tiruchi, Periyar University in Salem, and the Indian Institute of Science, Bengaluru, joined in, working without any fee.Professional crushers broke down the rocks and soil to the micro grain sizes sought by the ISRO-led team. Transporters moved the tonnes of this ‘lunar earth’ to ISITE, all free of charge, Dr. Annadurai recalls.These challenges were not there when he led the first lunar orbiting-only mission, Chandrayaan-1, as its project director.At the LTTF, the team spread the soil trucked in from Salem up to a height of about 2 metres. Studios were hired to illuminate the facility exactly as sunlight would play on the lunar terrain.On the Moon, the metre-long rover, weighing 27 kg, must move for about 500 metres during its expected life of 14 Earth days (one lunar day). Rover tests began as early as in 2015. The ISRO team had to reckon with the weak lunar gravity, about 16.5% of Earth’s. The rover’s weight was artificially reduced using helium balloons.Previous missions by other countries have suggested that the southern part of the Moon is mineral rich with the promise of water, which was first confirmed by the Chandrayaan-1 mission.Lunar south poleISRO Chairman K. Sivan recently said the Indian lander Vikram would be the first ever spacecraft to land at the lunar south pole.It has two site options, the craters Manzinus-C and Simpelius-N.The sites were picked after scouring through a few thousand lunar images from Chandrayaan-1 and other missions.For testing the lander, ISRO had a large test bed created at its new R&D campus at the Challakere Science City, some 400 km from Bengaluru. Vikram’s set of sensors, called the Hazard Detection and Avoidance (HDA) system, is a critical part of the mission.In the actual descent to the Moon, the lander hovers for a few seconds over a site and the sensors must assess whether the spot is flat enough for the lander’s legs: whether it has rocks that might topple the lander, and whether the lander can be steady to release the rover within it. If the spot is not safe, it must quickly rise and shift to a neighbouring spot and again assess if it is suitable to land on, all in seconds.Sometime in 2016, the URSC created several artificial ‘lunar’ craters at the Challakere site. Late that year the team put a test bed of lander sensors in a small ISRO plane and flew it over the craters to see if the sensors could read the terrain and find the right landing spot.According to Dr. Annadurai, the success of the landing depends on the sensors’ correctly guiding the lander to a safe site; and the fuel in the lander lasting for duration of the whole exercise.Other tests were conducted to clear the working of the lander’s propulsion system, its actuator and legs, and the rover’s movement.In a joint paper presented at the International Academy of Astronautics symposium in June 2017, Dr. Annadurai and his co-authors wrote: “One of the key elements essential for safe landing is the Hazard Detection and Avoidance (HDA) system. [It] comprises of several sensors… [which] provide information like lander’s horizontal velocity, vertical velocity, height above moon’s surface, relative position of the lander with respect to moon’s surface, and hazard/safe zone around the landing site.“The HDA system processes the inputs from various sensors, compares the data collected with the information already stored in the lander and provides the required inputs to the navigation and guidance system in real time to correct the trajectory at the end of rough braking to enable a safe and soft landing.” ISRO plans to land a rover on lunar south pole: Sivan Chandrayaan-2 will carry 14 Indian payloads ‘Chandrayaan-2’s lander and rover were tested on a simulated surface Newly designed cars are tested for road-worthiness on terrain where they would be driven, while new aircraft are test-flown in the skies. But where on earth did the Chandrayaan-2 mission’s lander and rover, which will head for the moon on July 15, check out their legs and wheels?More than a decade ago, even as the Chandrayaan-1 orbiter mission of 2008 was being readied, the Indian Space Research Organisation (ISRO) created a proto-Lunar Terrain Test Facility (LTTF) at its advanced satellite testing unit, ISITE, in Bengaluru. This, it did, by modifying a balloon research lab, about 30-40 m high, long and wide.At the time, ISRO was grappling with the task of indigenously executing the cryogenic stage for its GSLV MkII rocket. Any thought of sending a moon lander was a distant dream of low priority. Equipping the LTTF and making it look and feel like being on the moon was the first challenge. It needed lunar ‘soil’ with almost all its features and texture, lunar temperatures, low gravity and the same amount of sunlight as on the moon.Play VideoPlayUnmuteCurrent Time 0:00/Duration Time 0:00Loaded: 0%Progress: 0%Stream TypeLIVERemaining Time -0:00 Playback Rate1ChaptersChaptersdescriptions off, selectedDescriptionssubtitles off, selectedSubtitlescaptions settings, opens captions settings dialogcaptions off, selectedCaptionsAudio TrackFullscreenThis is a modal window.The media could not be loaded, either because the server or network failed or because the format is not supported.Caption Settings DialogBeginning of dialog window.

(Photo: PTI)HIGHLIGHTSMumbai residents held protest against BMC for failing to trace the 18-month-old missing infantThe protest March began from the residence of Divyansh, which was led by his father Divyansh had slipped into an open drain outside his residence on Wednesday eveningLocal residents of Goregaon East on Saturday along with family members of the 18-month-old Divyansh Singh, who drowned in an open drain on Wednesday, staged a protest against the (Brihanmumbai Municipal Corporation) for the civic body’s failure in tracing the missing infant.The protest March began from the residence of Divyansh, which was led by his father and family friend Shravan Tiwari.At the protest, residents shouted slogans against the civic body and complained about BMC’s incompetence in order to find the missing infant.Divyansh had slipped into an open drain outside his residence on Wednesday evening as Mumbai continued to witness heavy rains.Since then rescue efforts by the NDRF and BMC had been launched to find the baby boy.The rescue and search operation was carried out through the open drain leading to null in the radius of around 3 to 4 square kilometres, eventually leading to the creek, but did not yield any positive results.Finally, after the NDRF called off the search, BMC had also called off the search operation on Friday evening.Divyansh’s family, who were still praying for a miracle, expressed displeasure when they came to know that the civic body had called off the search operation.After repeated phone calls and messages, BMC officials on Saturday started digging drain upwards in which the kid had drowned.Several ducts and concrete slabs were removed but it didn’t help with any clue of the missing kid.By Saturday morning, a BMC team with an earthmover reached the spot and started removing the ducts and concrete slabs over the drain in upwards direction to look for the kid.A BMC official on the spot said that they were trying to see under the covered areas of drain suspecting that the kid might have gotten entangled in the cables passing from the drain. This attempt, too, was fruitless.Around 3:30 pm, locals led by Divyansh’s father Suraj and his friend Shravan Tiwari spearheaded a protest march to the BMC’s ward office in Goregaon west of the P South Ward.”We demand that the mayor of BMC should resign because it is their failure which has led to this incident. Since the past three days we waited that they will help and find the kid but they called off the operation,” said Shravan Tiwari, a family friend of Divyansh.”The ward officer never even bothered to meet us or visit the spot where the incident happened. We met her but the meeting has failed to provide anything concrete and the BMC officials have nothing to say. They should be punished and reprimanded for the shoddy job they do,” said Divyansh’s father Suraj.”We will continue our protest and agitate against the civic body’s lethargic attitude. I want justice for my child,” he added.Meanwhile, the police was yet to ascertain on what sections and against whom the FIR be registered as the infant’s body is yet to be found.Also, the CCTV the footage was being examined to see who was the person who had removed the concrete slab from the spot where the kid drowned.ALSO READ | Amit Shah directs officers to provide assistance to flood-affected statesALSO WATCH | Did this scooter fall into a rain-filled pothole’ in Mumbai?For the latest World Cup news, live scores and fixtures for World Cup 2019, log on to indiatoday.in/sports.
