Oklahoma State Honoring Members Of Basketball Program Who Died In Plane Crash 14 Years Ago Today

Posted on by

first_imgOklahoma State honors 2001 plane crash victims.On January 27th, 2001, the Oklahoma State basketball program suffered an unthinkable tragedy when eight members of its family (two players and six staffers and broadcasters) died in a plane crash while returning from a game in Colorado. In the years since that traumatic event, the 10 people who died in the crash –including the pilot and co-pilot–have been memorialized with a banner hanging in the rafters of OSU’s home court, Gallagher-Iba Arena, and a memorial located inside the Athletics Center. Also, each year, at the home game closest to the date of the crash, Oklahoma State honors the 10. This post from the Cowboys’ official athletics Instagram account has all the details on the ceremony before tonight’s game against Baylor: Very touching and appropriate tribute for those whose lives were inexplicably cut short, and it’s incredible to think 14 years has passed since this tragedy happened.last_img read more

On-Demand Lincoln Debuts Uber-Like Service, But With Your Own Car April 12, 2017 The chauffeur program will launch in select cities.center_img –shares Add to Queue Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Ever wanted to ride in your own car, but as a passenger? Lincoln will soon have your back — if you own a Lincoln.Ahead of the New York Auto Show, the luxury automaker announced that it’s piloting a new service called Lincoln Chauffeur. Currently available only in Miami, it allows owners of Lincoln vehicles to hail drivers to chauffeur them around.Related: 5 Surprising Things to Come Out of the Detroit Auto ShowOwners may not want to drive themselves for a number of reasons: They may want to avoid looking for parking or paying steep fees to leave their car at the airport during a trip. They may want their car returned to their home after their driver drops them off so someone else in their household can use it. They may even need a designated driver service and request that a Lincoln driver retrieve them and their car after an evening of drinking, according to Autoblog.It’s a solution for Lincoln owners who don’t want to allow their high-end vehicle to sit in their garages when it’s not convenient for them to drive — and who don’t want to settle for an unfashionable, inexclusive cab, Uber or Lyft.A startup called Dryver already does this, by the way. Its slogan is, “We drive your car, so you don’t have to.”The services Lincoln Chauffeur will provide won’t be limited to driving, however. The drivers will also be on call to run errands for users, such as pumping gas, picking up kids and buying groceries. They may even become personal assistants over time, as satisfied users will be able to request the same driver repeatedly.Related: You Won’t Believe This Luxe New Car Is a VolvoSan Diego Lincoln owners will get to try the service next, and other cities will follow later this year. New Lincoln buyers will get eight free hours of Lincoln Chauffeur, currently valued at $30 an hour.For those nervous about trusting a stranger with their keys, Lincoln has said that it will thoroughly vet all of its drivers. And unlike other companies that provide rides on-demand, Lincoln’s drivers will be employees, not independent contractors, providing an additional layer of liability for the company.

Register Now » Erin Griffith A Brief History of Uber’s Controversies Free Webinar | July 31: Secrets to Running a Successful Family Business –shares November 18, 2014 This story originally appeared on Fortune Magazine Next Article Silicon Valley’s most valuable startup could also be its most toxic. A scoop from BuzzFeed illuminated as much last night. At a private dinner, Emil Michael, Uber’s SVP of business, suggested a plan to spend $1 million on a revenge campaign against journalists, in particular Sarah Lacy, a writer who has criticized the ridesharing startup. Michael’s apparent plan involves using data, which the company has access to through its app, to dig up information about Lacy’s personal life, then publicly distribute the compromising information. He also talked about hiring opposition researchers to dig up more dirt.The news quickly ricocheted around Twitter. Taken on its own, the story may not have stirred up such a fierce reaction. But the sheer volume of Uber scandals is difficult to ignore. With each new one, Uber’s three constituents – customers, investors and drivers – are questioning the $18.2 billion company. (Kalanick issued an apology today on Twitter.) Below, a look at what got us here:Drivers behaving badlyAn Uber driver has been accused of kidnapping a female rider.An Uber driver was accused of attacking a rider in the head with a hammer.An Uber driver assaulted a rider. Another Uber driver, whopassed Uber’s background check, assaulted and abused a rider.An Uber driver hit and killed a six-year-old girl. The company avoided liability because its drivers are independent contractors rather than employees.An Uber driver was accused of rape. Another was accused of fondling a passenger.Driver treatmentUber drivers in New York and San Francisco have held protests and strikes for better pay and treatment.Uber has been accused of pushing its drivers intosubprime auto loans.Sexist commentsCEO Travis Kalanick joked about how desirable he is to women, thanks to Uber’s success. “We call that Boob-er,” he told a reporter.Sexist adsUber promoted its services in France by pairing riders with “hot chick” drivers and asking, “Who said women don’t know how to drive?”Playing dirty against competitorsKalanick has repeatedly trash-talked rival Lyft, at one point calling the service a clone on Twitter. Uber’s elaborate plans to sabotage Lyft include aggressively recruiting Lyft’s drivers and cancelling rides on the service to waste the drivers’ time.Uber has even tried to kneecap Lyft’s fundraising (whichFortune’s Dan Primack has argued is fair game; venture investor Fred Wilson disagrees).Playing dirty with the mediaUber tried to plant a fake story that painted a positive picture of life as an Uber driver in LA Weekly after the publication ran a critical story.Surge pricing during emergenciesUber’s famous free-market pricing strategy did not make an exception for Hurricane Sandy, when many New Yorkers were displaced and the cost of taking an Uber car doubled. After complaints, the company said it would cap surge-pricing in emergencies.Regulatory fights and protestsUber tussles with the legacy black car and taxi industry in almost every city it enters. Many cities have tried to outlaw the service. When Berlin banned Uber, the company flouted the government and continued to operate. In other instances, Uber’s presence that causes the commotions. In France, a protest of Uber got physical when an Uber car’s windows were broken and its tires slashed. In London, a protest stopped traffic.Now, Uber can’t even release an integration with Spotifywithout writers pointing out that the partnership “furthers the ongoing logistical process of dehumanizing Uber drivers.” That was supposed to be a fluffy product announcement.

The Driver Who Sued Uber Slams Offensive Settlement

Posted on by

first_imgClass Action Lawsuits Image credit: Reuters | Lucy Nicholson The Uber driver behind the lawsuit that threatened the company’s business model is now objecting to settling the case.In April, Uber announced that it had reached a $100 million settlement agreement in a court case that had gone on for three years. Douglas O’Connor filed suit against the company in 2013, claiming that Uber had misclassified its drivers as independent contractors and that they should be employees.The culmination of the case was announced in April with a $100 million settlement for drivers in California and Massachusetts.But in a court filing on Monday, O’Connor is now objecting to the settlement that bears his name, saying that it shortchanges drivers of billions.O’Connor said:”I am compelled to submit this declaration objecting to the class action settlement on behalf of myself and on behalf of the hundreds of thousands of other Uber Drivers in the State of California — and throughout the Country — who were at first given hope and a voice by the lawsuit bearing my name but now feel utterly betrayed and sold-out by an unjust settlement result that only benefits Uber.”In his objection, O’Connor claims that he never saw a copy of the settlement before Uber announced it in April. After it was announced, he claims that he was pressured into quickly signing the 100-page document.After reviewing the settlement, O’Connor doesn’t believe that the agreement is in the best interests of Uber drivers.He wrote:”Having now had the full opportunity to review the O’Connor settlement agreement, it is apparent that under the agreement, Uber drivers are being sold out and shortchanged by billions of dollars while sacrificing the determination of their classification as employees.”He initiated the case against Uber three years ago because he felt that the company misclassifying its drivers was “the most significant hazard to the economy and public safety,” he says. The settlement doesn’t answer that question.O’Connor says in the objection:”Unfortunately, the magnitude of this generational threat was given short shrift in the O’Connor class action as almost no meaningful discovery or depositions were taken, but where the average Uber driver will now receive an offensive settlement worth less than a tank of gas. I cannot in good conscience support this disastrous settlement agreement.”Uber declined to comment on the objection. Shannon Liss-Riordan, his former attorney, said that the things O’Connor is saying “are simply not true.”Liss-Riordan wrote in an email to Business Insider:”The case was at risk of being gutted by the Ninth Circuit and we made the choice we did, in consultation with our clients. Mr. O’Connor was not a lead plaintiff, and had not been certified to represent the class, but I kept him in the loop because the case bore his name. I believe the settlement was in the best interests of the class, in light of the risk we faced if having the case pulled out from under us by the Ninth Circuit. But if the court disagrees and thinks the settlement should not go forward for some reason, I would be more than happy to plow forward with it and do what I need to do.” Next Article May 17, 2016 Add to Queue 2019 Entrepreneur 360 List Biz Carsoncenter_img 3 min read This story originally appeared on Business Insider –shares The Driver Who Sued Uber Slams ‘Offensive’ Settlement Apply Now » The only list that measures privately-held company performance across multiple dimensions—not just revenue.last_img read more

Thalamus controls development of normal sleep and waking states study finds

Posted on by

first_imgReviewed by James Ives, M.Psych. (Editor)Oct 12 2018Consciousness requires continuous, internally generated activity in the brain. The modulation of this activity is the basis of the electroencephalogram (EEG) and of generation of sleep, dreams, and perception. Achieving such activity is thus an important milestone in normal brain maturation, which occurs around birth. Successful transition to this activity indicates a good prognosis for babies born prematurely and/or suffering from damage to the brain.To be functional as a dreaming, seeing, and thinking entity the brain need to achieve two milestones: continuity, which means that the brain is always active and state dependence, meaning brain activity is modulated by sleep, waking, and attention. The circuit mechanisms behind the development of continuity and state dependence in the brain have remained unknown, but have been widely assumed to be located in the cerebral cortex, the convoluted brain structure responsible for thought and perception.A team from the George Washington University (GW) has published a study in the Journal of Neuroscience suggesting instead that the thalamus, a tiny nucleus deep in the brain, actually controls the development of state dependence and continuity.”Our results indicate that cellular changes in the thalamus relay function may be critical drivers for the maturation of background activity,” Matthew Colonnese, PhD, associate professor of pharmacology and physiology at the GW School of Medicine and Health Sciences, said. “Humans undergo developmental transitions in brain activity before and near birth.”Related StoriesResearch team to create new technology for tackling concussionMercy Medical Center adds O-arm imaging system to improve spinal surgery resultsStudy provides new insight into longitudinal decline in brain network integrity associated with agingDrawing on previous work by Colonnese, his team used advanced techniques to record simultaneously from multiple brain regions to pinpoint the circuit change responsible for the acquisition of continuity and state dependence measured in the sensory cortex. They were surprised to learn that activity changes in the thalamus, rather than the local cortical circuitry or the interconnectivity of two structures, can explain most of these critical developmental milestones.”From a clinical perspective, certain things can go wrong in birth, like hypoxic-ischemic encephalopathy, brain injury caused by lack of oxygen to the brain, and the brain can revert to a state of discontinuity or never develop continuity,” said Colonnese. “These findings could help us understand the circuit basis of human EEG development to improve diagnosis and treatment of infants in vulnerable situations. By putting the development of the EEG on a mechanistic basis we hope to increase its utility in the clinic.”Colonnese and his team, which includes Yasunobu Murata, PhD, a research scientist in Colonnese’s lab at GW and co-author of the study, are working to develop a comprehensive atlas of EEG patterns and brain lesions that cause them to aid in this process.Now that they have established the thalamus is in control, he said, the next step is to further define what circuit changes occur in brain development so clinicians can pinpoint from an EEG what’s gone wrong in cases like hypoxic-ischemic encephalopathy.Source: https://smhs.gwu.edu/news/new-study-finds-thalamus-wakes-brain-during-developmentlast_img read more

Microgel powder reduces infection and promotes healing

Posted on by

first_imgReviewed by Kate Anderton, B.Sc. (Editor)Nov 14 2018While making smart glue, a team of engineers discovered a handy byproduct: hydrogen peroxide. In microgel form, it reduces bacteria and virus ability to infect by at least 99 percent.Hao Meng’s doctoral project focused on biocompatibility testing and pulling a sticky amino acid out of mussels. Glue-like catechol shows promise for smart adhesives — a small jolt of electricity can turn the stickiness on and off — but that’s not its only potential use.”In the process, Meng discovered the chemical reaction generated hydrogen peroxide as a byproduct of oxidation,” says Bruce Lee, associate professor of biomedical engineering and Meng’s PhD advisor at Michigan Technological University. “She started thinking, what if we could use the hydrogen peroxide?”The answer is yes, and the technology that makes this portable, healing disinfectant possible is the subject of a new paper published in Acta Biomaterialia. The work brought together an interdisciplinary team of engineers to explore not only the tech development but also the material’s physical and biological properties. The coauthors include Caryn Heldt, James and Lorna Mack Chair in Bioengineering, and Megan Frost, interim chair of the Department of Kinesiology and Integrative Physiology as well as an associate professor of biomedical engineering and an affiliated associate professor of materials science and engineering.Just like Jello After Meng first observed that her reactions created hydrogen peroxide, she started considering the best form to put the byproduct in. She wanted lots of surface area to power the chemical reaction and she wanted a way to reuse the material. So, the team made a microgel.”The gel is just like jello,” Lee says. “It’s a polymer network with a lot of water in it. And just like jello, we start with a liquid and solidify it into a shape.”Microgels are like tiny bubbles of jello. To the naked eye, the dry form is a nondescript powder. Suspend it in a solution with neutral or a slightly alkaline pH, such as distilled water or a saline solution like contact lens cleaner, and the hydrogen peroxide cycle gets rolling. Left to its own devices, the micron-sized microgels generated between one to five millimolars over four days. Once the microgel powder is dried again, the material basically resets, sits safely contained in a small bag, and can be reused. It’s like an on-demand bottle of disinfectant — without the bulky bottle and hazardous storage issues.Antimicrobial and AntiviralRelated StoriesNew research could help design algae that produces fuels and cleanup chemicalsNew protein target for deadly ovarian cancerAlternate cell growth pathway could open door to new treatments for metastatic cancersThe inspiration for that iconic brown bottle in the medicine cabinet didn’t start in a lab; the body naturally produces hydrogen peroxide to help heal cuts and the substance has been widely used medicinally to kill off bacteria and even viruses. Because the microgel powder continues to create and release hydrogen peroxide, its potency remains high, especially compared to the old-school cotton ball technique.The team studied the microgel’s effects on two common bacterial strains and two structurally different viruses. That includes the thin-walled and gram-positive Staphylococcus epidermidis, as well as the more impenetrable and gram-negative Escherichia coli (E. coli). They also looked at the extremely resistant non-enveloped porcine parovirus (PPV) and easier to inactivate enveloped bovine viral diarrhea virus (BVDV). Because of the hard protein casing around PPV, which makes it and other non-enveloped viruses more resistant to biocides, the team was pleasantly surprised to see that the microgel still reduced the virus’ ability to infect cells by 99.9 percent. (In technical terms, that’s a three log reduction value of infectivity.) With BVDV, they observed a 99.999 percent reduction in infectivity.From Camping to BattlefieldsThe possibilities are almost endless. Wherever a small bag can go, so could this technology. Whether it’s backcountry travel, space stations, remote clinics or war zones, a little bit of healing to prevent infection can go a long way. While Lee and his team say the tech is not quite ready for Amazon Prime, they are hopeful that the work shows promise for a variety of applications, perhaps even with antibiotic resistance.”We haven’t tested any antibiotic-resistant bacterial strains yet, but the more we can get away from using antibiotics in the first place, the better,” Lee says. “There’s still a lot of work to be done. We want to demonstrate under what conditions it promotes healing and how a cell responds to it. Hydrogen peroxide at high concentrations can also kill cells, so we need to have a balance that changes for different cell types.”Lee recently received funding from the Department of Defense Office of the Assistant Secretary of Defense for Health through the Defense Medical Research and Development Program to continue this line of research. What started with a sticky protein’s waste will be refined into a lightweight, portable and recyclable microgel powder with enough oomph to kick even the most stubborn bacterial and viral infections.

Alzheimers disease protection from exercise hormone irisin

Posted on by

first_imgBy Dr. Ananya Mandal, MDFeb 11 2019Exercising is good for health and there is yet another reason for it. Exercise is known to release certain endogenous hormones called “feel good” hormones or endorphins. Yet another hormone may be released from the body when a person exercises – this is called irisin. Irisin is found to be protective against Alzheimer’s disease finds a new study. The results of the new study were published in the journal Nature Medicine. Irisin – Image Credit: Ibreakstock / Shutterstock The study led by researchers at the Columbia University’s Vagelos College of Physicians and Surgeons, co-authored by Dr. Ottavio Arancio, a Professor of pathology and cell biology and of medicine at the institute, finds evidence of the positive role exercise could play in brain health. According to the researchers, there was evidence that exercise can reduce the risk of getting Alzheimer’s disease. The reason for this was not known.The hormone irisin was found a few years ago. It was noted that irisin was released in blood during exercise and physical activity. It was hypothesized that irisin could play a role in energy metabolism of the body. This new research has shown that irisin is capable of promoting new neuron growth in the brain. It is especially beneficial at the hippocampus region of the brain which is necessary for memory and learning. Arancio said, “This raised the possibility that irisin may help explain why physical activity improves memory and seems to play a protective role in brain disorders such as Alzheimer’s disease.”The team including those from Federal University of Rio de Janeiro in Brazil and Queens University in Canada extensively studied the connection between irisin and A;zheimer’s disease. They gathered brain tissue samples from brain banks and noted that irisin is normally present in the hippocampus region of the brain and among those suffering from Alzheimer’s disease, there us a reduction in levels of this hormone in the hippocampus.Related StoriesHealthy lifestyle lowers dementia risk despite genetic predispositionExercise during pregnancy can promote bone health of both mother and childStudy highlights the need for larger Alzheimer’s drug trials that intervene much earlierThe team used laboratory mice to assess the benefits provided by irisin to the brain. They noted that presence of irisin in the brain of mice can protect their memory and preserve the nerve connections called the synapses. They then disabled irisin in the hippocampi of the mice brains. Thereafter there was a decline in memory and damage to the synapses was noted. When irisin levels were raised, there was an improvement in brain health, the researchers noted.As a next step the researchers assessed the type of exercise that could raise irisin in the brain and benefit brain health. It is known that beta amyloid protein causes formation of clumps within the brain that leads to symptoms of Alzheimer’s disease. The mice were made to swim daily for five weeks and were administered infusions of beta amyloid protein. Despite the infusions, these mice did not develop memory impairment akin to Alzheimer’s disease, they noted. This means that despite the pathology, irisin has the capacity to stop the progressive memory loss associated with Alzheimer’s disease say the researchers. Now if irisin was blocked in the swimming animals using a specific drug, these mice developed memory impairments due to infusions of the beta amyloid.The researchers hope that this study can extrapolate into new therapies for Alzheimer’s disease based on irisin. Arancio in a statement said, “In the meantime, I would certainly encourage everyone to exercise, to promote brain function and overall health. But that’s not possible for many people, especially those with age-related conditions like heart disease, arthritis, or dementia. For those individuals, there’s a particular need for drugs that can mimic the effects of irisin and protect synapses and prevent cognitive decline.”Source: https://www.nature.com/articles/s41591-018-0275-4last_img read more

Eccentric exercises could help fatigued dancers prevent injury improve jump performance

Posted on by

first_imgOur study suggests fatigued dancers may lack the strength to control their legs when absorbing the forces from the landing, affecting the technique and artistry of their jump as well as increase risk for injury. Targeted eccentric exercises could enable them to control their movements when they’re tired. This may help them consistently perform the jump in good form as well as reduce the risk of injury.”Danielle N. Jarvis, PhD, ATC, senior author of the study and assistant professor of kinesiology at California State University Northridge Researchers studied 17 professional ballet dancers who performed 10 sauté jumps before and after a protocol designed to mimic a ballet class or rehearsal. They used a 12-camera motion capture system and force plates to collect three-dimensional movement data while the dancers performed the jumps. The researchers determined that the dancers’ ankles flexed more deeply upon landing when they were fatigued (30.32 degrees) compared to before they were tired (28.88 degrees). Fatigue also lessened the peak landing forces, meaning the dancers landed softer. The force plates determined they landed with 1.72 times their body weight when fatigued, vs. 2.13 times their body weight before they were fatigued. The motion capture system showed that while the dancers achieved the same jump height, they did not point their toes as proficiently when fatigued.Related StoriesDoing more harm than good: Scientists uncover harmful effects of dietary supplementsResearchers identify new sarcoma familial risk gene’Text neck’ may be causing bone spurs in young peopleBased on their findings, the researchers surmise that eccentric exercises could help lengthen and strengthen the calf muscles, counteracting the effects of fatigue. Eccentric muscle contractions occur in the lowering phase of a traditional movement (e.g. lowering into a squat, or lowering the arms after a biceps curl), causing a muscle to lengthen rather than shorten. One such exercise involves standing on both toes and then lowering one foot in a very slow, controlled manner, rather than letting the heel come down quickly.”Athletic trainers can work with dancers to identify eccentric movements they can do to achieve better control and jump more effectively,” said Dr. Jarvis. “We believe that if dancers are better able to control – and not collapse into – the landing, they are more likely to use the proper technique and may be less likely to get injured.” Source:National Athletic Trainers’ Association (NATA) Reviewed by James Ives, M.Psych. (Editor)Jun 26 2019Exercises that lengthen leg muscles may help dancers counteract fatigue, preventing injury and allowing for a more perfected jump technique, suggests research being presented at the National Athletic Trainers’ Association (NATA) 70th Clinical Symposia & AT Expo.Researchers studied how well trained ballet dancers performed the classic sauté jump – a vertical jump with feet pointing down – before and after becoming fatigued by dancing. When tired, the dancers’ form suffered, both in air and on landing.Dance is a very physically demanding activity and injuries are common. However, there is limited research examining the biomechanics of dance movements and the effects of fatigue on dance performance and technique. The researchers sought to assess fatigue and resulting movement patterns to shed light on how athletic trainers can better work with dancers to prevent injuries.last_img read more

Higher levels of physical activity not linked to greater volume or activity

Journal of Clinical Endocrinology and Metabolism. doi.org/10.1210/jc.2018-01312. Studies that analyze the effect of regular physical activity, from a molecular point of view, are necessary to help us understand the mechanisms that mediate the therapeutic effects of exercise in humans.”Francisco Miguel Acosta Manzano, doctoral student in Biomedicine, UGR’s International School for Postgraduate Studies Reviewed by James Ives, M.Psych. (Editor)Jul 5 2019A study conducted by researchers from the University of Granada (UGR) has found that, in contrast to scientific thinking to date, higher levels of physical activity are not linked to a greater volume or activity of brown adipose tissue (BAT). BAT is a thermogenic organ that burns glucose and fats, releasing the energy that is produced in the form of heat.When BAT is activated, it consumes glucose and lipids, partially preventing them from being stored in other tissues, such as white adipose tissue (or common fat), which is located, for example, around the abdomen.Over the last decade, several studies have unequivocally confirmed the presence of BAT in human adults. BAT is a thermogenic organ equipped to dissipate energy in the form of heat through the so-called “uncoupling protein”. Therefore, it has been postulated that generating a greater volume of BAT, and increasing its activity, could be a potential strategy for combatting obesity and associated comorbidities, such as type 2 diabetes.Researchers have tended to channel their efforts into identifying strategies to help improve BAT function safely over the long term. On this premise, previous studies have suggested that raising levels of physical activity could be an effective strategy for increasing the volume and activity of BAT. However, the data from extant studies conducted on humans are both scarce and contradictory.In this new study, published in the Journal of Clinical Endocrinology and Metabolism, the UGR scientists investigate, for the first time, the link between objectively-measured levels of physical activity and the quantity and activity of BAT. The latter are measured by means of proton-emission tomography combined with computed tomography (using a radiopharmaceutical known as18F-Fluorodeoxyglucose). This study was performed on a sample of sedentary young adults, whose BAT was measured (the largest cohort of its kind to date). The sample comprised 87 women and 43 men, with an average age of 22 years.Related StoriesLiver fat biomarker levels linked with metabolic health benefits of exercise, study findsResearchers to examine if a ‘snacktivity’ approach to physical activity is effective in improving healthMobile phone app may help boost and maintain physical activity in womenThis study was part of the ACTIBATE (Activating Brown Adipose Tissue Through Exercise) project (http://profith.ugr.es/actibate), which was implemented by the University of Granada during 2014-2017. It was funded by Spain’s then-Ministry of Economy and Competitiveness, via the Health Research Fund of the Carlos III Institute of Health (PI13/01393).No link identifiedThe authors of the article observed that there was no link between the levels of physical activity and the volume and activity of BAT, even after adjusting the analyses for covariables that could be influencing the results. Nor was the time spent being sedentary associated with the volume and activity of BAT, they noted. The authors concluded that, although physical activity is one of the main interventions recommended in the prevention of chronic diseases such as obesity and type 2 diabetes, other mechanisms beyond an increase in the volume and activity of BAT could be mediating its beneficial metabolic effects. These findings contradict the results of previous studies, and call into question the role of exercise in improving BAT function.last_img read more

When the silicon is exposed to an electric field, a force is exerted on the silicon crystals, causing the spring to compress or extend slightly.These tiny movements are made visible via an optical solution—an additional grid located above the movable silicon grid is lined up so precisely that the grid openings on one grid are concealed by the other. When an electric field is present, the structure moves slightly out of perfect alignment with the fixed grid, allowing light to pass through the openings. This light is measured, from which the strength of the electric field can be calculated by an appropriately calibrated device.Prototype achieves impressive levels of precisionThe new silicon sensor does not measure the direction of the electric field, but its strength. It can be used for fields of a relatively low frequency of up to one kilohertz. “Using our prototype, we have been able to reliably measure weak fields of less than 200 volts per metre,” says Andreas Kainz. “This means our system is already performing at roughly the same level as existing products, even though it is significantly smaller and much simpler. Other methods of measurement are already mature approaches—we are just starting out. In the future, it will certainly be possible to achieve significantly better results with our microelectromechanical sensor.” Citation: New sensor for measuring electric field strength (2018, January 25) retrieved 18 July 2019 from https://phys.org/news/2018-01-sensor-electric-field-strength.html In a break from the design principle employed by all other measuring devices to date, a research team at TU Wien has now developed a silicon-based microelectromechanical (MEMS) sensor. Devised in conjunction with the Department for Integrated Sensor Systems at Danube University Krems, this sensor has the major advantage that it does not distort the very electric field it is currently measuring. An introduction to the new sensor has also been published in the electronics journal Nature Electronics.Distorting measuring devices”The equipment currently used to measure electric field strength has some significant downsides,” explains Andreas Kainz at TU Wien. “These devices contain parts that become electrically charged. Conductive metallic components can significantly alter the field being measured, an effect that becomes even more pronounced if the device also has to be grounded to provide a reference point for the measurement.” Such equipment also tends to be relatively impractical and difficult to transport. read more

In Denmark Airbnb to report hosts rent to tax authorities

first_img Explore further Taxation minister Carsten Lauritzen says Airbnb “has committed to report data so their hosts pay taxes.” He says Airbnb will inform Danish taxation authorities of the number of renting days and its users’ total income.The deal announced Thursday closes a loophole in which hosts had to report to tax authorities on a voluntary basis.Patrick Robinson, director of Airbnb’s Public Policy in Europe, said it “will allow that to be fairly and clearly regulated.”Danish political parties on Tuesday agreed to limit room-rental services to a maximum of 70 days a year per property. Denmark says online room-rental platform Airbnb will start to automatically report its users’ deals to taxation authorities, the first country to do so.

Four ways blockchain could make the internet safer fairer and more creative

Posted on by

first_img The lowdown on Libra: what consumers need to know about Facebook’s new cryptocurrency Explore further Provided by The Conversation Citation: Four ways blockchain could make the internet safer, fairer and more creative (2019, July 12) retrieved 17 July 2019 from https://phys.org/news/2019-07-ways-blockchain-internet-safer-fairer.html The internet is unique in that it has no central control, administration or authority. It has given everyone with access to it a platform to express their views and exchange ideas with others instantaneously. But in recent years, internet services such as search engines and social media platforms have increasingly been provided by a small number of very large tech firms. On the face of it, companies such as Google and Facebook claim to provide a free service to all their users. But in practice, they harvest huge amounts of personal data and sell it on to others for profit. They’re able to do this every time you log into social media, ask a question on a search engine or store files on a cloud service. The internet is slowly turning into something like the current financial system, which centrally monitors all transactions and uses that data to predict what people will buy in future.This type of monitoring has huge implications for the privacy of ordinary people around the world. The digital currency Bitcoin, which surfaced on the internet in 2008, sought to break the influence that large, private bodies have over what we do online. The researchers had finally solved one of the biggest concerns with digital currencies—that they need central control by the companies that operate them, in the same way traditional currencies are controlled by a bank. The core idea behind the Bitcoin system is to make all the participants in the system, collectively, the bank. To do this, blockchains are used. Blockchains are distributed, tamper-proof ledgers, which can record every transaction made within a network. The ledger is distributed in the sense that a synchronised copy of the blockchain is maintained by each of the participants in the network, and tamper-proof in the sense that each of the transactions in the ledger is locked into place using a strong encrypting technique called hashing.More than a decade since this technology emerged, we’re still only beginning to scratch the surface of its potential. People researching it may have overlooked one of its most useful applications—making the internet better for everyone who uses it.Help stamp out hateIn order to use services on the internet such as social media, email and cloud data storage, people need to authenticate themselves to the service provider. The way to do this at the moment is to come up with a username and password and register an account with the provider. But at the moment, there’s no way to verify the user’s identity. Anyone can create an account on platforms like Facebook and use it to spread fake news and hatred, without fear of ever being identified and caught.center_img Our idea is to issue each citizen with a digital certificate by first verifying their identity. An organisation like your workplace, university or school knows your identity and is in a position to issue you with a certificate. If other organisations do the same for their members, we could put these certificates on a publicly accessible blockchain and create a global protected record of every internet user’s identity.Since there’d be a means for identifying users with their digital certificate, social media accounts could be linked to real people. A school could create social media groups which could only be accessed if a student had a certificate issued to them by the school, preventing the group being infiltrated by outsiders.Never forget a password againA user could ask for a one-time password (OTP) for Facebook by clicking an icon on their mobile phone. Facebook would then look up the user’s digital certificate on the blockchain and return an OPT to their phone. The OTP will be encrypted so that it cannot be seen by anyone else apart from the intended recipient. The user would then login to the service using their username and the OTP, thereby eliminating the need to remember passwords. The OTP changes with each login and is delivered encrypted to your phone, so it’s much more difficult to guess or steal a password.Vote with your phonePeople are often too busy or reluctant to go to a polling station on voting days. An internet voting system could change that. Digital currencies like Zerocash are fully anonymous and can be traced on the blockchain, giving it the basic ingredients for a voting system. Anyone can examine the blockchain and confirm that a particular token has been transferred between two parties without revealing their identities.Each candidate could be given a digital wallet and each eligible voter given a token. Voters cast their token into the wallet of their preferred candidate using their mobile phone. If the total number of tokens in the wallets is less than or equal to the number issued, then you have a valid poll and the candidate with the most tokens is declared the winner. No more tech companies selling your dataPeople use search engines everyday, but this allows companies like Google to gather trends, create profiles and sell this valuable information to marketing companies. If internet users were to use a digital currency to make a micropayment—perhaps one-hundredth of a cent—for each search query that they perform, there would be less incentive for a search company to sell their personal data. Even if someone performed a hundred search queries per day they would end up paying only one cent—a small price to pay for one’s privacy.Blockchain technology started as a means for making online transactions anonymous, but it would be shame for it to stop there. The more researchers like me think about its potential, the more exciting possibilities emerge. This article is republished from The Conversation under a Creative Commons license.

Exodus of MLAs keeps Karnataka ruling coalition on tenterhooks

Posted on by

first_imgRELATED Cong-JD(S) combine mulls options to placate rebels, including change of CM The ruling Janata Dal Secular (JD-S)-Congress coalition government in Karnataka is making a last-ditch effort to save itself after 12 Congress legislators submitted their resignation to the Assembly Speaker on Saturday. The Congress, in an effort to sort out differences in the party, has called its Legislature Party meeting on Tuesday at Vidhana Soudha in Bengaluru, while the JD(S) held a series of meetings under its party supremo and former prime minister HD Deve Gowda. The JD(S)-Congress coalition government faces a crisis, as disgruntled MLAs – three from JD(S) and nine from the Congress – tendered their resignation letters to the Assembly Speaker’s office on Saturday. This sudden development comes just days ahead of the Monsoon Session of the Karnataka Legislature (July 12).The JD(S) and Congress leaders on Sunday were seen persuading the rebel legislators to take back their resignation letters. AICC General Secretary in-charge of Karnataka, K C Venugopal, rushed to Bengaluru to save the government. He was disappointed as a meeting with the rebel MLAs which was slated for Sunday was cancelled as most of them were away in Mumbai.“The BJP is doing it. It’s their money and power that is responsible for the present turmoil. The BJP is luring the MLAs to join their fold. They are offering money to the MLAs and are exploiting their displeasure over denial of ministerial post,” said former chief minister and Congress Legislative Party leader Siddaramaiah.Former Union minister Mallikarjun Kharge too blamed the BJP. “The Centre is directly involved in the turmoil. BJP is trying to kill the democracy. The Congress will not tolerate it.”BJP denies involvementThe BJP, which has been accused of trying to destabilise the Karnataka government by triggering ‘Operation Lotus’, has denied the allegations. BJP General Secretary P Muralidhar Rao dubbed the allegations levelled by Congress and JD(S) leaders as baseless. “This is nonsense. It’s a baseless allegation. By making allegations against another party that has nothing to do with the internal affairs of Congress, they’re not going to gain anything,” he said.State BJP chief B S Yeddyurappa said, “The BJP is in no way involved in the rebellion being faced by the coalition government. We are watching from the sidelines, as the collapse of this government is imminent.”He further said the BJP would stake a claim for forming the next government if the JD(S)-Congress government falls due to its ‘own contradictions’. Yeddyurappa said: “ People are not ready for the elections. Elections are a burden on State exchequer. Being a team of 105 members in the Assembly and as a responsible national political party, we have responsibility to find a solution to present political problems.” For its survival, JD(S)-Congress coalition is contemplating making former chief minister Siddaramaiah as the Chief Minister for the second time and PWD Minister H D Revanna (brother of Kumaraswamy) as the Deputy Chief Minister. It is also considering making Mallikarjuna Kharge the next Chief Minister.
