Co2 record at mauna loa, the music video: The sounds of climate change Posted: 30 Sep 2016 06:41 PM PDT Two scientists put the carbon dioxide record at Mauna Loa to music, and made a music video of climate change.

From Pokemon go to birdwatching: How we express our inner hunter Posted: 30 Sep 2016 06:40 PM PDT Interested in birding or wildlife photography? Enjoy playing Pokemon Go and catching imaginary creatures? If so, you may simply be expressing your inner hunter. So says a new study from Vladimir Dinets, a University of Tennessee, Knoxville, research assistant professor of psychology.

CDC urging men at risk of Zika to postpone fatherhood Posted: 30 Sep 2016 12:19 PM PDT CDC today announced updates to its interim guidance for pre-pregnancy counseling and prevention of sexual transmission of Zika based on ongoing assessment of available data, primarily extending the timeframe for men with possible Zika exposure but no Zika symptoms to wait before attempting pregnancy with their partner and extending the time for use of condoms by these men to protect against sexual transmission of Zika virus infection.

World's tallest wood building completed: 18 storeys Posted: 30 Sep 2016 11:58 AM PDT The mass wood structure and façade has been completed for UBC's Brock Commons student residence -- the world's tallest wood building at 18 storeys (53 metres, about 174 feet) -- four months ahead of schedule, showcasing the advantages of building with wood.

Ancient global cooling gave rise to modern ecosystems Posted: 30 Sep 2016 11:44 AM PDT Sea surface temperatures dipped dramatically during a period from 7 million to 5.4 million years ago, a time of massive global ecological change, scientists have discovered.

Formaldehyde damages proteins, not just DNA Posted: 30 Sep 2016 11:43 AM PDT Formaldehyde, a common toxicant and carcinogen recently subjected to new federal regulations, may be more dangerous than previously thought, a new study suggests.

Details of mysterious Utah Zika-related death: Transmission by tears or sweat Posted: 30 Sep 2016 11:30 AM PDT The first Zika virus-related death in the continental U.S. occurred in June of this year, but even now, months later, two aspects of this case continue to puzzle health experts. First, why did this patient die? It is quite rare for a Zika infection to cause severe illness in adults, much less death. Second, how did another individual, who visited the first while in the hospital, become ill from Zika? This second patient did not do anything that was known at the time to put people at risk for contracting the virus.

Fat cells that amplify nerve signals in response to cold also affect blood sugar metabolism, researchers report Posted: 30 Sep 2016 10:05 AM PDT When exposed to cold, clusters of cells within the body's white fat become beige -- a color change that reflects the creation of more energy-producing mitochondria, cellular components that enable cells to burn calories and give off heat. But since white fat cells have very few nerves, how do beige fat cells get the message that it's cold outside?

First evidence of deep-sea animals ingesting microplastics Posted: 30 Sep 2016 09:04 AM PDT Scientists working in the mid-Atlantic and south-west Indian Ocean have found evidence of microfibers ingested by deep sea animals including hermit crabs, squat lobsters and sea cucumbers, revealing for the first time the environmental fallout of microplastic pollution.

Noncoding mutations disrupt cooperative function of 'gene families' in rare genetic disorder Posted: 30 Sep 2016 09:04 AM PDT Scientists say they are one step closer to understanding the genetic mechanism of a rare, complex, multiple-gene disorder called Hirschsprung's disease. Their results suggest that many patients develop the disease when multiple mutations in gene regulatory sequences of a specific gene combine to destroy the normal cooperative function of a whole network of genes.

Registry data used to examine oral anticoagulant therapy, appropriate use Posted: 30 Sep 2016 09:02 AM PDT The American College of Cardiology's National Cardiovascular Data Registry was the source of data for research published throughout 2016, including a study examining if atrial fibrillation patients are being prescribed oral anticoagulants, how appropriate use criteria correlates to angioplasty rates and the variation among racial groups for revascularization procedures.

Lake brownification, eutrophication decrease the content of essential fatty acids in fish used in human diets Posted: 30 Sep 2016 09:02 AM PDT Eutrophication and brownification change phytoplankton community structure and decrease the production of essential omega-3 fatty acids in lakes. Perch growing in oligotrophic clear-water lakes contain 1.5-1.9 times more essential omega-3 fatty acids than those grown in eutrophic and brown-water lakes.

Advancing non-animal testing methods: First set of novel knowledge tools published Posted: 30 Sep 2016 09:02 AM PDT An adverse outcome pathway, or AOP, is a highly structured way of describing a toxicological process which can lead to an adverse health effect in humans or wildlife, caused by an unsafe exposure to a chemical substance. The first five adverse outcome pathways have now been published by experts. The AOPs are novel knowledge management tools in toxicology and are useful for supporting risk assessment to human health. They are also valuable for helping to avoid animal testing through the use of alternative methods.

Final descent image from Rosetta spacecraft Posted: 30 Sep 2016 08:37 AM PDT A new image of comet 67P/Churyumov-Gerasimenko was taken by the European Space Agency's (ESA) Rosetta spacecraft shortly before its controlled impact into the comet's surface on Sept. 30, 2016. The final descent gave Rosetta the opportunity to study the comet's gas, dust and plasma environment very close to its surface, as well as take very high-resolution images.

Genetically engineered crops are safe, review of studies finds Posted: 30 Sep 2016 06:02 AM PDT Genetically engineered crops are no different from conventional crops in terms of their risks to human health and the environment, according to a new report.

What's in a face? Study shows puberty changes facial recognition Posted: 30 Sep 2016 06:00 AM PDT Faces are as unique as fingerprints and can reveal a great deal of information about our health, personalities, age, and feelings. Researchers recently discovered adolescents begin to view faces differently as they prepare for the transition to adulthood. The ability of adolescents to retune their face processing system, from showing a bias toward adult female faces as children, to preferring peer faces that match their own developmental stage in puberty, is part of the social metamorphosis that prepares them to take on adult social roles, say the authors of a new report.

Heavy hitters: Obesity rate soars among professional baseball players Posted: 30 Sep 2016 05:59 AM PDT Major League Baseball players have become overwhelmingly overweight and obese during the last quarter century, say health researchers. They found that the athletes' weight held steady for over 100 years, with the majority of them weighing in at what is considered "normal," -- i.e., with a body mass index (BMI) between 18.5 and 24.9. However, around 1991 the average player's BMI began to rise, and over the last 25 years nearly 80 percent of players fall into the overweight or obese category with a BMI above 25.

Universal flu vaccine designed by scientists Posted: 30 Sep 2016 05:58 AM PDT Scientists have designed a new generation of universal flu vaccines to protect against future global pandemics that could kill millions. Researchers researchers have devised two universal vaccines; a USA-specific vaccine with coverage of 95% of known US influenza strains; and a universal vaccine with coverage of 88% of known flu strains globally.

With worrisome animal research, more focus needed on effects of cannabis on human development Posted: 30 Sep 2016 05:08 AM PDT In this new era of legalized marijuana, far too little research has been conducted on the effect of cannabis on the development of human embryos, say researchers who scoured medical literature on the topic and found what they say is worrisome animal research.

Caffeine-based compounds show promise against Parkinson's disease Posted: 30 Sep 2016 05:08 AM PDT Two caffeine-based chemical compounds have been developed that show promise in preventing the ravages of Parkinson's disease. Parkinson's disease attacks the nervous system, causing uncontrolled shakes, muscle stiffness, and slow, imprecise movement, chiefly in middle-aged and elderly people. It is caused by the loss of brain cells (neurons) that produce dopamine, an essential neurotransmitter that allows neurons to "talk" to each other.

Controlled rogue wave created in realistic oceanic conditions Posted: 30 Sep 2016 05:06 AM PDT Potentially extremely dangerous realistic rogue waves - also called as freak waves - can now be controlled and generated at will in laboratory environments, in similar conditions as they appear in the ocean. This will help us not only to predict oceanic extreme events, but also in the design of safer ships and offshore rigs. In fact, newly designed vessels and rig model prototypes can be tested to encounter in a small scale, before they are built, realistic extreme ocean waves.

'Advances and Refinements' in Neuromodulators for Facial Rejuvenation Posted: 29 Sep 2016 12:20 PM PDT Plastic surgeons have a range of effective products and minimally invasive techniques for patients seeking to reverse the signs of facial aging. A review and update on facial rejuvenation using botulinum toxin "neuromodulators" has now been completed.

Setting the stage from diagnoses to dimensions Posted: 29 Sep 2016 06:28 AM PDT The case-control method, where researchers compare patients with a particular disease to healthy control participants, has increased understanding of disease-related effects at a group level. However, psychiatric pathology complicates assumptions of the method – that the illness can be defined and that patients cleanly fit the definition. Although psychiatry has characterized different diagnoses, patients within a diagnosis vary widely and symptoms often overlap diagnostic labels.

New way to define proarrhythmic risk? Posted: 29 Sep 2016 06:28 AM PDT There generally are two approaches used to indirectly assess proarrhythmic risk, but some researchers believe that human induced pluripotent stem-cell derived (hiPSC)-cardiomyocytes offer an opportunity to change the paradigm.
