Facial hair on pilots: Study busts myth Posted: 21 Sep 2018 11:01 AM PDT Do airline pilots need a clean-shaven face to ensure a proper seal on face masks during emergency cabin depressurization? A recent study offers an answer. |
Emissions from most diesel cars in Europe greatly exceed laboratory testing levels Posted: 21 Sep 2018 11:01 AM PDT A new study reports that Volkswagen is not the only auto manufacturer to make diesel cars that produce vastly more emissions on the road than in laboratory tests. The study finds that in Europe, 10 major auto manufacturers produced diesel cars, sold between 2000 and 2015, that generate up to 16 times more emissions on the road than in regulatory tests. |
Cooking with wood or coal is linked to increased risk of respiratory illness and death Posted: 21 Sep 2018 06:24 AM PDT Burning wood or coal to cook food is associated with increased risk of hospitalization or dying from respiratory diseases. |
Kiwi teenagers less fit than a generation ago Posted: 21 Sep 2018 06:24 AM PDT New Zealand teenagers are less fit and weigh more than their parents were at the same age, new University of Otago research reveals. |
Spray coated tactile sensor on 3D surface for robotic skin Posted: 21 Sep 2018 06:24 AM PDT Scientists have reported a stretchable pressure insensitive strain sensor by using an all solution-based process. The solution-based process is easily scalable to accommodate for large areas and can be coated as a thin-film on 3-dimensional irregularly shaped objects via spray coating. |
Extra Arctic observations can improve predictability of tropical cyclones Posted: 21 Sep 2018 06:24 AM PDT Scientists have found that additional weather observations in the Arctic can help predict the track and intensity of tropical and mid-latitude cyclones more accurately, improving weather forecasting of extreme weather events. |
Eye infection in contact lens wearers can cause blindness Posted: 21 Sep 2018 05:29 AM PDT A new outbreak of a rare but preventable eye infection that can cause blindness, has been identified in contact lens wearers in a new study. The research team found a threefold increase in Acanthamoeba keratitis since 2011 in South-East England. |
Pre-clinical success for a universal flu vaccine offers hope for third generation approach Posted: 21 Sep 2018 05:29 AM PDT Researchers have demonstrated pre-clinical success for a universal flu vaccine in a new article. |
Overwhelming evidence shows hepatitis C treatment effective for people who inject drugs Posted: 20 Sep 2018 05:32 PM PDT Researchers are calling on an end to discriminatory health and illicit drugs policies, based on overwhelming evidence that new hepatitis C therapies are effective at curing the virus in people who inject drugs. |
Land-based bird populations are at risk of local extinction Posted: 20 Sep 2018 05:32 PM PDT A new report finds that land-based bird populations are becoming confined to nature reserves in some parts of the world -- raising the risk of global extinction -- due to the loss of suitable habitat. |
Octopuses given mood drug 'ecstasy' reveal genetic link to evolution of social behaviors in humans Posted: 20 Sep 2018 02:52 PM PDT By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or 'ecstasy,' scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree. |
Gut fungus exacerbates asthma in antibiotic-treated mice Posted: 20 Sep 2018 01:10 PM PDT A non-pathogenic fungus can expand in the intestines of antibiotic-treated mice and enhance the severity of allergic airways disease, according to a new study. The findings suggest that alterations in gut microbiota induced by intestinal fungi might be a previously unrecognized but potentially important risk of antibiotic therapy in patients with asthma and other respiratory diseases. |
We are bombarded by thousands of diverse species and chemicals Posted: 20 Sep 2018 01:10 PM PDT Scientists have measured the human 'exposome,' or the particulates, chemicals and microbes that individually swaddle us all, in unprecedented detail. |
Gambling monkeys help scientists find brain area linked to high-risk behavior Posted: 20 Sep 2018 01:10 PM PDT Monkeys who learned how to gamble have helped researchers pinpoint an area of the brain key to one's willingness to make risky decisions. |
Plug-and-play technology automates chemical synthesis Posted: 20 Sep 2018 01:09 PM PDT Researchers have developed an automated chemical synthesis machine that can take over many tedious aspects of chemical experimentation, freeing chemists to spend time on the more analytical and creative aspects of their work. |
A behavioral intervention for cancer patients that works Posted: 20 Sep 2018 01:09 PM PDT This is a story about something rare in health psychology: a treatment that has gone from scientific discovery, through development and testing, to dissemination and successful implementation nationwide. In a new study, researchers found that a program designed at The Ohio State University to reduce harmful stress in cancer patients can be taught to therapists from around the country and implemented at their sites, and effectively improves mood in their patients. |
Posted: 20 Sep 2018 01:09 PM PDT Barely heard of a couple of years ago, quinoa today is common on European supermarket shelves. The hardy plant thrives even in saline soils. Researchers have now determined how the plant gets rid of the excess salt. |
Major breakthrough in controlling the 3D structure of molecules Posted: 20 Sep 2018 01:09 PM PDT Scientists have made a major breakthrough in chemical synthesis that now makes it possible to quickly and reliably modify the 3D structure of molecules used in drug discovery. The new method allows scientists to employ cross-coupling reactions to generate new compounds while controlling their 3D architecture. |
Manganese plays a key role in bacterial infection Posted: 20 Sep 2018 01:09 PM PDT The ability to acquire manganese during infection is essential for the virulence of Enterococcus faecalis in animals, according to a new study. |
NASA balloon mission captures electric blue clouds Posted: 20 Sep 2018 01:08 PM PDT Scientists share mesmerizing new images of electric blue clouds from NASA's PMC Turbo balloon mission that flew in over the Arctic in July 2018. |
Investigational steroid mirrors prednisone's benefits while taming its side effects Posted: 20 Sep 2018 01:08 PM PDT A head-to-head trial comparing the decades-old steroid, prednisone, and a promising new steroid, vamorolone, finds both act on the same key set of genetic pathways involved in controlling inflammation, indicates a new study. However, the study suggests the new investigational steroid doesn't activate several additional pathways involved in prednisone's bevy of undesirable side effects. |
Full, but still feasting: Mouse study reveals how urge to eat overpowers a signal to stop Posted: 20 Sep 2018 01:08 PM PDT A new study explores the mystery of what drives eating past the point of fullness, at the most basic level in the brain. It shows that two tiny clusters of cells battle for control of feeding behavior -- and the one that drives eating overpowers the one that says to stop. It also shows that the brain's own natural opioid system gets involved -- and that blocking it with the drug naloxone can stop over-eating. |
Genomic dark matter activity connects Parkinson's and psychiatric diseases Posted: 20 Sep 2018 01:08 PM PDT Using a new technique known as laser-capture RNA seq, that involves cutting out dopamine neurons from a human brain section with a laser, investigators have cataloged more than 70,000 novel elements active in these brain cells. |
Study documents poor mental and physical health in rural borderland community members Posted: 20 Sep 2018 01:08 PM PDT A new study offers vivid picture of health consequences of life events and chronic strain among foreign-born Mexicans in farm working communities. |
Reducing false positives in credit card fraud detection Posted: 20 Sep 2018 10:15 AM PDT Consumers' credit cards are declined surprisingly often in legitimate transactions. One cause is that fraud-detecting technologies used by a consumer's bank have incorrectly flagged the sale as suspicious. Now researchers have employed a new machine-learning technique to drastically reduce these false positives, saving banks money and easing customer frustration. |
