Explore further Over the past two years, researchers have further investigated the properties of dark stars, as well as how these unusual stars may help scientists better understand dark matter, black holes, and other astronomical features. In a new study, the group of scientists that originally theorized dark stars has presented a review of the research on dark stars and predicted future areas of research. Katherine Freese of the University of Michigan; Paolo Gondolo of the University of Utah; Peter Bodenheimer of the University of California, Santa Cruz; and Douglas Spolyar, currently with Fermilab, have published their results in a recent issue of the New Journal of Physics.As the scientists explain, dark stars would represent a new phase of stellar evolution – the first phase, occurring just 200 million years after the big bang. At that time, dark matter densities in the early universe were higher than they are today, and the first stars are predicted to have formed in the middle of dark matter haloes (which are precursors to galaxies) as opposed to today’s stars that are scattered about the edges of a galaxy. According to the theory, these early stars grew larger by accreting mass from their surroundings, pulling in dark matter along with the surrounding gas. Inside these stars, weakly interacting massive particles (WIMPs), a candidate for dark matter, could accumulate. Since WIMPs can be their own antiparticles, they could annihilate to produce a heat source. If the dark matter density was high enough, this heating would dominate over other heating (or cooling) mechanisms, such as nuclear fusion. Compared with fusion, WIMP annihilation is a very efficient power source, so that only a small amount of dark matter is required to power the star.“Dark stars are a natural consequence of WIMPs as dark matter particles … although it took us a while to put the necessary ingredients together to realize this!” Freese told PhysOrg.com. “At the time we proposed these objects in 2007, we didn’t realize that they are really stars in the sense of being hydrostatically stable objects that shine and produce visible light. Now that we have succeeded in finding the stellar structure of these objects, we understand their properties: they are giant puffy objects (like suns that extend out to the radius of the earth) and the light they produce looks a lot like that from the Sun. But they grow to become a thousand or even a million times as massive! These are our new results since we first began our research in this area.” (PhysOrg.com) — The first stars in the universe may have been very different from the stars we see today, yet they may hold clues to understanding some of the mysterious features of the universe. These “dark stars,” first theorized in 2007, could grow to be much larger than modern stars, and would be powered by dark matter particles that annihilate inside them, rather than by nuclear fusion. In the early universe, dark stars would have emitted visible light like the Sun, but today their light would be redshifted into the infrared range by the time it reaches us, and so dark stars would be invisible to the naked eye. Citation: Stars Fueled by Dark Matter Could Hold Secrets to the Universe (2009, November 3) retrieved 18 August 2019 from https://phys.org/news/2009-11-stars-fueled-dark-secrets-universe.html As the scientists explained, modern stars eventually burn up their hydrogen and transition into other star types on the main sequence diagram. On the other hand, dark stars can keep growing indefinitely, as long as they keep accreting dark matter from their surroundings. If not disturbed, these stars could potentially grow to be tens of thousands of times larger than the Sun. However, most dark stars would probably eventually stray from their locations at the centers of dark matter haloes. Their dark matter fuel would run out, so that the stars would start to collapse and eventually be powered by fusion from the stars’ normal hydrogen atoms, and finally collapse into black holes. The scientists calculated that dark stars have a lifetime of at least one million years, and perhaps billions of years; they might even still be around today.The scientists predict that it should be possible to detect dark stars, either by detecting their light with upcoming telescopes, or by using neutrino telescopes to measure neutrinos from dark stars. Compared with conventional main sequence stars, dark stars that have run out of dark matter fuel and started using fusion would be much larger, cooler, and “puffier.” And while dark stars ultimately become black holes, the first stars in the traditional view (without dark matter) turn into supernova, giving the researchers a point of comparison.“These supernova populate the universe with element abundances in very precise ratios (the ratio of even to odd elements is very precise),” Freese explained. “However, we predict that this doesn’t happen in dark stars. So this distinction provides a measurable test of the two different scenarios. These element abundances should be measured in the next five years and then we’ll know.”By measuring the properties of dark stars with future instruments, scientists could discover detailed properties of dark matter. Since different dark matter particles produce different annihilation products, measurements could reveal information about the properties of dark matter, such as their mass, their annihilation mechanisms, etc. Freese also plans to investigate whether dark stars could become large enough to produce the giant black holes that are currently unexplainable. “So far we have built up dark stars to 1,000 times the mass of the Sun,” she said. “But if they keep accumulating dark matter by capturing it from the surroundings, they can end up much larger: possibly even a million times as massive as the Sun. This is my immediate goal as far as research endeavors. Such supermassive objects were first proposed in the ‘60s by Fowler and Hoyle, but nobody knew how to make them. If this is right, it certainly helps explain the enormous black holes seen in the universe that nobody knows how to explain: when the supermassive stars die, they become black holes. There are billion-solar-mass black holes seen at basically the time the first galaxies formed, as well as the ones in centers of galaxies.”More information: Katherine Freese, Peter Bodenheimer, Paolo Gondolo, and Douglas Spolyar. “Dark stars: a new study of the first stars in the Universe.” New Journal of Physics 11 (2009) 105014.Copyright 2009 PhysOrg.com.

EXPO21XX, which has been providing electronic exhibitions (or e-expos) since 2001 for a variety of industries, launched the virtual University Robotics Platform in 2008. The e-expos offer a convenient and free alternative to the conventional expo by taking advantage of the internet and the latest multimedia technology. Similar to a real-life expo, EXPO21XX’s e-expos are organized into halls, corridors, and individual stands. The University Robotics Platform, for example, is located in e-Hall05 of the Automation e-expo (where there are currently 37 e-Halls). On the Universities Robotics Platform, you can learn about many different robotics projects that don’t always make it to the news headlines (and some that do). For example, visitors can watch videos of the following robots:*A robotic jaw that simulates human chewing behavior, which was designed by researchers at the Mechatronics and Robotics Research Group at Massey University in New Zealand.*A robot that uses Facebook, which was designed by researchers the Interactive Robots and Media Laboratory at the United Arab Emirates University. *A robot that performs stereotactic microsurgery, which implants an electrode in the brain for a therapy called deep brain stimulation that could help treat Parkinson’s disease. The robot was designed by researchers at the Institute for Robotics and Cognitive Systems at the University of Luebeck in Germany. *A giant six-legged ant-like robot that skitters across the ground and flips itself over to walk “upside down.” The robot was developed by researchers at the Active Structures Laboratory at the Université Libre de Bruxelles in Brussels, Belgium, for gait studies. *A brain-actuated robotic wheelchair constructed by researchers at the Neurotechnology Lab at the University of Zaragoza in Spain. The wheelchair is being designed to provide people with severe neuromuscular disabilities with a certain degree of mobility. Prominent among the presenters is Prof. Peter Bock of George Washington University (Computer Science) who was invited to publish a complete presentation of the functionality of ALISA (Adaptive Learning Image and Signal Analysis) and the results from his recent funded projects with Bosch and then DTRA (Defense Threat Reduction Agency of the DOD). The Universities Robotics Platform continues to grow, with a few stands currently being reserved for additional universities. If you want to get a glimpse of the future, this is definitely worth checking out.Visit the site at www.expo21xx.com/automation21xx/university.htm (PhysOrg.com) — In an effort to bring together the top academic robotics labs under one roof, a project called EXPO21XX has created an online exhibition to showcase the diversity in today’s robotics research. At one website, robotics researchers and enthusiasts can view the projects underway in more than 100 university robotics labs from around the world.

The discovery was posted on the Central Bureau’s Transient Object Confirmation Page which led to follow-up observations by other teams around the world. It’s real, and not only is it bright enough for amateur astronomer’s to view, but it’s the closet known supernova explosion since 1987. Initial study has revealed the supernova to be classified as 1a, the type described by astronomers as “standard candles” because their brightness is uniform enough to allow for using them to measure distances across the universe. Sometimes they start out as a white dwarf, pulling in material from around them until they reach a critical mass and explode. Other times they are the result of two such stars (binaries) colliding.What’s perhaps most exciting about this newest observation is that it’s so close (just 11.4 million light years from us) that it’s likely that images of the star that exploded have been previously recorded by different telescopes around the globe which means scientists might be able to watch the process that led to the supernova occurring, something that has never been seen before. If that turns out to be the case, other space researchers note, the stage could be set for allowing for reducing uncertainties in measuring dark energy—standard candle observations are the means by which such theories first came to exist after all. Also, while the explosion has undoubtedly unleashed a torrent of neutrinos, its unlikely monitors here on Earth will notice much of an uptic in activity due to distance and them getting lost in other sources.Because of the timing of the discovery, it appears that there is more to come—it’s going to get brighter over the next few days before growing dimmer and dimmer, eventually fading to black. That means that anyone wishing to observe a supernova as its happening can do so—likely a once in a lifetime opportunity. Binoculars should be enough, though a telescope would be much better. Universe Today has published a map to help those looking find it. © 2014 Phys.org More information: www.astronomerstelegram.org/?read=5786remanzacco.blogspot.nl/2014/01 … upernova-in-m82.html Credit: UCL/University of London Observatory/Steve Fossey/Ben Cooke/Guy Pollack/Matthew Wilde/Thomas Wright

DOI: 10.1016/j.tcb.2017.08.009 © 2017 Phys.org (Phys.org)—Piece by piece, the circuit diagram for electron transport in the mitochondria has come closer to completion. Each new structure obtained for any of the five respiratory complexes further constrains the assembled puzzle. Eventually, big blocks are arranged into their final placements. The exact composition of the biggest block, the so-called megacomplex, has long eluded researchers. Now, after imaging 140 individual subunits down to 3.9 anstrom resolution, the Full Monty has been laid bare. Researchers describe in Cell exactly how the human respiratory megacomplex is put together and appears to function. Journal information: Cell Researchers demonstrate how a molecular barrel structure serves various functions in the mitochondria Explore further Gone are the simple days. No more crude diagrams with complexes lined up in the membrane in a row from one to five with electrons and their mobile carriers sequentially traveling through from left to right. Bring on the stoichiometry, and bring on the 2-D. Stoichiometry means that in reality, each complex is actually represented in the megacomplex at a specific copy number. These extra copies need to go somewhere in any accurate representation. Not only that, but the smaller electron carriers need a space to hang out. They also need to be present within channels that either remain local to the megacomplex or possibly diffuse away to others. The final geometry will dictate where separate electron paths merge or bifurcate, and where they are most likely to run in reverse.The picture of the megacomplex (MC) that has emerged has the following stoichiometry: MCI2II2III2IV2. This means that complexes I,II,III,& IV are each present in duplicate while complex V is absent. It is configured within the membrane into a circular structure with the dimeric CIII located at the center and fed by peripheral CI and CIV complexes. The CII complexes are apparently not essential requirements to the core structure but rather are theorized to be wedged into gaps as needed. The authors also found evidence for a lightweight rendition of the megacomplex that can sometimes be assembled with just a single CI complex.The central positioning of the CIV dimer suggests a certain logic. CIV, or cytochrome oxidase, is the terminal resting ground for electrons entering the chain. Those that make it this far have been lowered down the reduction potential hierarchy as far as they can go. Here, they are sunk into waiting oxygen molecules, which are then exhausted as molecules of water. High potential electrons packaged as NADH enter the complex at its perimeter and are funneled into the center. The absence of C5 complexes may not be so unusual, considering that they are typically found as rows of “V’-shaped dimers that contort the membrane into regions of high curvature at bends in the cristea. With the basic structure in hand, the researchers were able to suggest a few basic principles of operation. Their inclusion and placement of CII effectively explains reverse electron transport from succinate to NADH. The proposed geometry also creates a sealed Q-pool (a lipid-soluble electron carrier) which is accessible to both CI and CII. The authors were also able to pinpoint the identity and locations of several lipid molecules that secure the complex within the membrane, specifically, several pivotal molecules of phosphatidylethanolamine, phosphatidylcholine, and cardiolipin. They were also able to identify preferred or most efficient electron transfer pathways, which in turn constrain how many electrons can simultaneously be transferred among active carriers.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Among the immediate benefits of this new work is that many of the previously incompletely understood pathogenic mutations in respiratory proteins now make sense. Prior to having any megacomplex structure, researchers had no choice but to focus on how mutations affect the structure or function of individual complexes. As it turns out, most of the recorded mutations in core subunits Ci and CIII target are in residues involved in protein-protein interaction sites between complexes. (For example, disease-associated mutations in subunits NDUFV1, NDUFS1, ND1, ND5, and ND6 in CI and subunit MT-CYB in CIII). This shows the futility trying to look only at single proteins and subunits in the absence of the bigger picture.It should be mentioned that previous efforts to define respiratory complex stoichiometry have obtained slightly different results depending on which organs and species were studied. Potato, cow, sheep, and yeast, which don’t always even have a CI complex to speak of, have all been studied. It is not surprising that different circumstances may call for different stoichiometry and form. Different megacomplex structures would entail different advantages for substrate channeling, catalytic enhancement, sequestration of reactive intermediates, or structural stabilization. One study that looked specifically at heart mitochondria set the ratio for oxidative phosphorylation complexes I:II:III:IV:V as 1:1.5:3:6:3. In this case, the authors called their complex the “respirasome.” With the respiratory megacomplex now presumably cracked, the next big step forward is to pop some of the other superstructures of the mitochondrial double membrane system into models to predict why cristea look the way they do. The massive TIM-TOM import complexes span both membranes and are intimately associated with the mitoribosomes that translate mitochondrial proteins. The mitoribosomes, in turn, are localized to underlying membrane-associated nucleoids that house copies of the mtDNA. By way of analogy to the nucleolus of the nucleus, this composite nucleoid-ribosome structure has been termed the ‘mitochondriolus.” Other critical import complexes are in the mix of players that vie for critical membrane real estate. The malate-aspartate shuttle, for example, is the most important shuttle in the brain and equilibrates major metabolites between mitochondria and cytosol. The citrate-pyruvate shuttle for fatty acid synthesis and the glycerol phosphate shuttle (at least for brown fat and insect flight muscle) must also find homes where they can get on well with the immediate neighbors.The endemic organization of proteins into these megastructures suggest that mitochondria might resemble a hard crystal more than a fluid protoplasm. Yet somehow, they appear remarkably supple when it comes to fusion and fission. What happens to their membrane structure under these kinds of changes? Are the complexes temporarily disassembled and solubilized like the primary cilium and centriole of regular cells during mitosis? One fascinating new clue emerges from work showing that mitochondria connect to one another through ‘nanotunnels’ of their own construction. These nanotunnels are completely different (as far as we know) from the cytoskeleton-infused brand of ‘tunnelling nanotubes’ that cells themselves use to transfer whole mitochondria to one another.A recent review from Martin Picard and his colleagues in Trends in Cell Biology suggests one way that these nanotunnels might form when mitochondria are fixed to the cytoskeleton. If motor proteins like kinesin get hold of a patch of a fixed mitochondria, it could pull out a thin nanotunnel as the kinesin motors against another microtubule. The stiff body of the mitochondria and its membrane structure would presumably remain intact. This projection could then encounter another mitochondria to which it becomes attached.Picard previously showed that about half of the mitochondria within cardiac muscle have intermitochondrial junctions (IMJs) and cristae that line up into regular patterns that extend across mitochondrial networks. This uncanny network alignment is unlikely to arise from recent fission events because heart mitochondria are fixed in place and show minimal fission/fusion dynamics. The IMJs have recently been shown to control contractility by rapidly uncouplinglinked mitochondria when their own membranes are depolarized. One thing that would be of immediate interest, here, is to re-examine respiratory subunit stoichiometry in human heart mitochondria to complement the results reported here for human embryonic kidney cells.
Kolkata: Nine persons were killed and others injured in lightning strikes and thunderstorm across the state.Three persons were killed and some others injured after they were struck by lightning in separate incidents in Murshidabad, while one person died in the same district after a wall fell on him during a thunderstorm on Wednesday morning.Three more were killed in Nadia. Two were killed in North 24-Parganas, while one was killed in North Dinajpore. Also Read – Heavy rain hits traffic, flightsA thunderstorm, coupled with rain, lashed the district on Wednesday morning. According to an administrative official from the district, there was heavy shower in various parts of Murshidabad for more than three hours, when the accidents took place. The regional meteorological centre at Alipore has predicted thunderstorm in the city and its adjoining districts on late Wednesday night.According to the police, two among the deceased were from Indrani village under Kandi sub-division, while the other was a resident of Bharatpur. Whereas in the third incident, a 35-year-old man, supposedly a manager of a brick kiln, died when a wall of the brick kiln fell on him at Sagardighi area of the same district. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedOliul Seikh (45) and Basidur Seikh (15), both residents of Indrani village, were returning home after ploughing a field when lightning struck them. The victims died at the spot. After being informed, police recovered their bodies and sent them to Kandi Sub-Divisional Hospital for an autopsy. In the other incident, a class V student, Sajib Seikh, was playing in the rain with some of his companions at Bharatpur when lightning struck them. Two of his associates Roni Seikh (19) and Sohail Seikh (16) received critical injuries in the incident. They are undergoing treatment at Kandi Sub-Divisional Hospital. It may be mentioned here that at least 13 people were killed and 20 others had been injured after lightning struck various parts of the state on Monday morning. Selim Seikh (35) died when a wall inside a brick kiln fell on him at Sagardighi during the storm. The victim was the manager of the brick kiln. Three other workers of the brick kiln were injured in the incident. They were rushed to Murshidabad Medical College and Hospital by the local residents. One person was killed when portion of a wall collapsed and fell on him at Sagardighi area of the district, the police said. It may be mentioned here that after Monday’s incident in which 13 people were killed, various district authorities had issued an alert to all the blocks, urging people not to be in the open or working in the field to avert such incidents.
A new study has linked the consumption of energy drinks to serious cardiovascular disorders possibly due to the caffeine and other stimulants they contain.The researchers from Mayo Clinic, Rochester, examined the effect of energy drink consumption on hemodynamic changes, such as blood pressure and heart rate. Anna Svatikova and her colleagues randomly assigned 25 healthy volunteers (aged 18 years or older) to consume a can (480ml) of a commercially available energy drink and placebo drink within five minutes, in random order on two separate days, a maximum two weeks apart. Also Read – ‘Playing Jojo was emotionally exhausting’The placebo drink, selected to match the nutritional constituents of the energy drink, was similar in taste, texture, and colour but lacked caffeine and other stimulants of the energy drink.The researchers found that caffeine levels remained unchanged after the placebo drink, but increased significantly after energy drink consumption.The energy drink’s consumption elicited a 6.2 per cent increase in systolic blood pressure while diastolic blood pressure increased by 6.8 per cent. Also Read – Leslie doing new comedy special with NetflixThe average blood pressure increased by 6.4 per cent after consumption of the energy drink. There was no significant difference in heart rate increase between the two groups, the researchers found.The average norepinephrine level increased from 150 pg/ml to 250 pg/ml after consumption of the energy drink and from 140 pg/ml to 179 pg/ml after placebo.“These acute hemodynamic and adrenergic changes may predispose to increased cardiovascular risk,” the authors observed.The study was presented at the American Heart Association’s Scientific Sessions 2015.
Women are at par with men in education but have failed to secure equal access to quality jobs and representation in the government, finds a global study that suggests the need for greater policy interventions to close gender barriers.The findings, from more than 150 countries, showed that women have reached 91 per cent of the education that men have. Yet, they have reached only 70 per cent of the male rate of employment. In more than half the world’s countries, female education rates are now similar, or greater, than men, up from 33 per cent in 1990. Despite these gains, the paper published in the Journal of African Development, showed that women’s employment rates are 30 per cent lower than men’s – even less in some regions of Asia, Latin America, the Middle East and Africa. Also Read – ‘Playing Jojo was emotionally exhausting’The share of women employed in the relatively high-paying industrial sector compared to men has dropped 20 percentage points since 1990. “Men have more of the high paying jobs, so women are squeezed into lower-paid positions. And female unemployment continues to be about 30 per cent higher than men’s, worldwide; so those women are not able to earn their own livelihood,” said Stephanie Seguino, economist at University of Vermont in US. Greater exclusion from high-paying jobs and a disproportionate amount of unpaid household work, including care for children and ageing parents, offer two key reasons for women’s lower employment and income, the researchers said. Also Read – Leslie doing new comedy special with NetflixFurther, the gender gap is seen to be widest in political representation. Overall, women share of parliamentary seats is 25 per cent compared to men’s. But, political representation for women has increased from 14 per cent in 1990 when compared to men. Legislative bodies in some nations, including Haiti and Qatar, still have no female members.Whereas countries such as Canada, Rwanda, Norway have adopted political gender based quotas to improve female representation in government. “Without women, governments are more likely to spend taxpayer money in ways that disproportionately benefit men – or at least ignore the extra burdens on women,” Seguino explained.
Kolkata: The Special Operation Group (SOG) Baruipur District Police and Kultali police station have unearthed an illegal arms factory at Kultali in South 24-Parganas on Thursday night.During a search operation police seized several firearms, unfinished firearms and apparatus for manufacturing such firearms. Two persons have been arrested in this raid. Sources informed that the sleuths are suspecting more persons are involved in this matter. According to the police, Baruipur District Police got a tip-off on Thursday about an illegal arms factory that is operational at Ambikanagar in Kultali. Also Read – Rain batters Kolkata, cripples normal lifeThe police identified a house owned by one Biswanath Mondal. After the sleuths were sure that Biswanath is the person behind running of the arms factory, Baruipur Police and Kultali police station formed a team and raided his house late on Thursday night. During the raid, the sleuths found 4 long single barrel firearms, 2 one shoter pipe gun, 6 rounds of live ammunition, six live bombs and some unfinished firearms. Several apparatus such as iron pipes, springs, wooden long arms bats, iron rods, firing pins, a drill machine, a polish Machine, a hand lathe machine and a few iron blades were also recovered.

After interrogating the duo, the sleuths came to know about a person from Bihar who used to manufacture the firearms and he has gone to Bihar to celebrate Chhath. Before this person came to Bengal, several miscreants used to manufacture arms using Biswanath’s house. They used to manufacture small firearms — the sound produced while making those were very low. Thus, no one in the area suspected something fishy. Sources informed that police will take the duo in to custody and will interrogate for more information. The sleuths are also checking if any more illegal firearms factory is being operational in any part of the district.

What will you do to find yourself at complete rest: Reading, being with nature, being on your own, listening to music or doing nothing in particular? Better choose one fast for your own well-being as you grow old.According to the world’s largest survey of more than 18,000 people from 134 different countries on this topic, over two thirds (68 per cent) of the public would like more rest.Nearly a third (32 per cent) of respondents said they need more rest than the average person, while 10 per cent think they need less. Also Read – Add new books to your shelf“The survey shows that people’s ability to take rest, and their levels of well-being, are related. These findings combat a common, moralising connection between rest and laziness,” said lead researcher Felicity Callard, social scientist at Durham University in Britain. Rest – a much broader category than sleep – has physical, mental and spiritual components, the study said. The online survey – rest test – found that those who felt they needed more rest scored lower in terms of well-being. Also Read – Over 2 hours screen time daily will make your kids impulsiveSimilarly, those who responded saying they think they get more rest than average or do not feel the need for more rest, had well-being scores twice as high as those who wanted more rest. This suggests that the perception of rest matters, as well as the reality, the researchers observed.In addition, people found reading (58 per cent), being in the natural environment (53.1 per cent), being on their own (52.1 per cent), listening to music (40.6 per cent), doing nothing in particular (40 per cent) as the top five most restful activities that is often done alone. “It’s intriguing that the top activities considered restful are frequently done on one’s own,” Callard said.“Perhaps it’s not only the total hours resting or working that we need to consider, but the rhythms of our work, rest and time with and without others,” he added. The survey asked respondents to state how many hours of rest they had within the last 24 hours. On average, being younger and having a higher household income was associated with having fewer hours of rest. Further, those with caring responsibilities or in shift work which included nights also reported fewer hours of rest.“This survey shows just how crucial it is to our well-being to ensure people do have time to rest. We can begin to try to work out what the optimum amount of rest might be and how we should go about resting,” explained Claudia Hammond, presenter of Radio 4’s All in the Mind and associate director of Hubbub – an international team of scientists, humanists, artists and broadcasters in London. The survey was presented during BBC Radio 4’s programme –The Anatomy of Rest.

Firdaus Jahan was admitted to CMRI and gave birth to a boy child on April 1 in 2017. Right after birth the infant faced problems while passing stool. Thereafter, the patient was referred to Dr Biswajit Bhaduri, who had been attached to the hospital as a pediatric surgeon. On April 3, the doctor told the family members of the patient that the infant was required to undergo an immediate surgery.

It was said surgery was needed to create a stoma for passing stool. After the baby recovers, another surgery would be conducted to reverse the stoma so that the infant can pass stool in a natural process. On April 10, the first surgery was conducted on the patient to create the stoma and later discharged from the hospital. For the next three months, the patient was under the treatment of that doctor. The second operation was performed on the patient on July 11 of the same year after which the baby started suffering from high fever and his body was found to be swollen. An X-ray was conducted on the patient and the doctor suggested to go for another surgery (third) to create a parallel line inside his abdomen. The family members of the baby lodged a complaint at the local police station after a member was allegedly forced to sign on a white paper by the hospital authorities. The baby eventually died and the family members registered a compliant with the WBCERC. After conducting a probe, the commission found that the degree obtained by the doctor from an institution abroad is not recognised by the MCI and the WBMC. The hospital authorities have been asked to pay compensation. In another judgement, the WBCERC asked Spandan Diagnostic Centre to pay Rs 5,000 to the family members of a patient whose blood test report came out wrong in November 23 in 2017. The diagnostic centre also failed to submit ‘Run Validity Record’ to the WBCERC.
Playing the video game Tetris hours after a distressing incident may help prevent the symptoms of post-traumatic stress disorder (PTSD), a new study has found.Researchers including those from Karolinska Institutet in Sweden studied about 71 motor vehicle accident victims, of whom half received the intervention (recalled the trauma briefly and then played Tetris) while waiting in the hospital emergency department, and half performed another task, all doing so within six hours of the accident.

Researchers also found that the intrusive memories diminished more quickly.”Our hypothesis was that after a trauma, patients would have fewer intrusive memories if they got to play Tetris as part of a short behavioural intervention while waiting in the hospital Emergency Department,” said Emily Holmes of Karolinska Institutet.

As rows disappear, more shapes fall and the longer the game lasts, the higher the score.”Since the game is visually demanding, we wanted to see if it could prevent the intrusive aspects of the traumatic memories from becoming established i.e by disrupting a process known as memory consolidation,” Holmes said. “The first week after trauma can be important for our patients, who have to go home, recover and look after themselves, which can be hard to do if you’re getting intrusive memories of the trauma, often several a day,” said Lali Iyadurai of Oxford University.Post-traumatic stress disorder (PTSD) can affect people who have experienced war, torture, rape, road accidents or other kinds of situations in which they felt their life, or that of another person, was in danger, researchers said

Even as more and more youngsters use dating apps for fun or to find the love of their life, new research warns that these apps are vulnerable to hacks, putting the users at risk of getting their locations and real names revealed. The study by global cyber security company Kaspersky Lab showed that many dating apps do not handle users’ sensitive data with sufficient care.”That’s no reason not to use such services. You simply need to understand the issues and, where possible, minimise the risks,” Kaspersky Lab said in a statement. In a survey conducted by Kaspersky Lab found that people turn to online dating for a variety of reasons. People share information with others too easily when they are dating online, with a quarter admitting they share their full name publicly on their dating profile.The experts studied nine popular mobile online dating apps – Tinder, Bumble, OkCupid, Badoo, Mamba, Zoosk, Happn, WeChat, Paktor – and identified the main threats for users.The researchers discovered that four of the nine apps allow potential criminals to figure out who is hiding behind a nickname based on data provided by users themselves.

Arizona’s DeAndre Ayton and Duke’s Marvin Bagley III were selected with the first two picks of last night’s draft, but for one year in high school the two top NBA rookies actually played together on a terrifying super team at Hillcrest Prep in Mesa, Arizona.In 2015, Ayton – the nation’s top rated junior – and Bagley – the country’s top soph – left California high schools to join up at the recently established basketball academy. The two only played 12 games together before Bagley’s dad yanked him from the school, midway through the season, after a disagreement with the coach and enrolled III at Sierra Canyon in L.A.The two never won a title together because they didn’t finish the season, but did manage to each post 30-point double doubles in a win. Hillcrest won the high school national title with just Ayton in 2017. It’s scary to think how good they would have been had Bagley stayed.

Uh, yeah, go take a look at that tape Hue and let us know what you find out.
