Atom-thick CCD Could Capture Images

December 19, 2014 3:25 pm | by Rice Univ. | News | Comments

An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices, according to researchers.                     


Image of the Day: Researchers Recreate Yellowstone's Thermal Springs

December 19, 2014 3:02 pm | by The Optical Society | News | Comments

Researchers have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park's hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus.


Drones Can Help Explain How Tornadoes Form

December 19, 2014 2:54 pm | by Associated Press, Dan Elliott | News | Comments

Researchers say they have collected promising weather data by flying instrument-laden drones into big Western and Midwestern storms. Now, they want to expand the project in hopes of learning more about how tornadoes form.                        


Environmentalists Sue EPA Over Water Quality

December 19, 2014 2:46 pm | by NRDC | News | Comments

The Natural Resources Defense Council and the Environmental Defense Center have sued the Environmental Protection Agency (EPA) to strengthen standards to prevent pollution from stormwater, one of the nation’s most widespread forms of water pollution.  More than a decade ago a federal appeals court ordered EPA to strengthen those protections, but the agency has failed to take action.


Good News: Quantum Physics Just Got Less Complicated

December 19, 2014 2:00 pm | by Centre for Quantum Technologies at the National Univ. of Singapore | News | Comments

Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has proven that two peculiar features of the quantum world previously considered distinct are different manifestations of the same thing.


OCD May Be Product of Brain Running Amuck

December 19, 2014 2:00 pm | by Univ. of Cambridge | News | Comments

New research suggests that misfiring of the brain's control system might underpin compulsions in obsessive-compulsive disorder (OCD). The research is the latest in a series of studies investigating the possibility that compulsions in OCD are products of an overactive habit-system.


Type O Blood Linked to Lower Diabetes Risk

December 19, 2014 2:00 pm | by Diabetologia | News | Comments

A study of more than 80,000 women has uncovered different risks of developing type 2 diabetes associated with different blood groups, with the biggest difference being a 35 percent increased risk of type 2 diabetes found in those with group B, Rhesus factor positive (R+) blood, compared with the universal donor group O, Rhesus factor negative (R-).


This Year @ NASA, 2014

December 19, 2014 11:00 am | Podcasts | Comments

Here’s a look at some of the top NASA stories of 2014 Neil Armstrong-Apollo 11: “That’s one small step for [a] man; one giant leap for mankind.” With 2014 marking the 45th anniversary of Neil Armstrong’s historic first step on the moon, NASA outlined plans for America's next giant leap in space exploration -- to send astronauts to Mars. To prepare for that leap, NASA stepped up development in 2014 of many game-changing technologies and capabilities.


Expectant Fathers Have Changing Hormones, Too

December 19, 2014 7:00 am | by Univ. of Michigan | News | Comments

Impending fatherhood can lower two hormones— testosterone and estradiol— for men, even before their babies are born, according to a study. Other studies indicate that men's hormones change once they become fathers, and there is some evidence that this is a function of a decline after the child's birth. This is the first to show that the decline may begin even earlier, during the transition to fatherhood.


Science Announces 2014’s Top 10 Breakthroughs

December 19, 2014 7:00 am | by American Association for the Advancement of Science | News | Comments

The Rosetta spacecraft caught up with the comet known as 67P/Churyumov-Gerasimenko beyond Mars this August, and its preliminary results— along with the studies it will allow in the near-future— top this year's list of the most important scientific breakthroughs, according to the editors of Science.


Moving to Cities is Linked to Diabetes in Developing World

December 19, 2014 7:00 am | by Endocrine Society | News | Comments

One factor that can raise a person’s risk of developing diabetes and other metabolic problems is chronic exposure to the stress hormone cortisol. Cortisol can counteract insulin, the hormone that regulates blood sugar, and slow the body’s production of it. As people in developing nations relocate from rural areas to cities, the increased stress is affecting their hormone levels and making them more susceptible to diabetes.


Single Protein Linked to Multiple Allergic Reactions

December 19, 2014 7:00 am | by Johns Hopkins Medicine | News | Comments

Researchers have identified a single protein as the root of painful and dangerous allergic reactions to a range of medications and other substances. If a new drug can be found that targets the problematic protein it could help smooth treatment for patients with conditions ranging from prostate cancer to diabetes to HIV.


Tinsel Has a Rich History

December 19, 2014 7:00 am | by ACS | Videos | Comments

It's been a holiday decoration staple for decades, and it turns out that silver stuff hanging from your tree has quite a storied past. Tinsel has been made out of everything from real silver to lead.


Ibuprofen Linked to Long Lifespan in Several Species

December 19, 2014 7:00 am | by Texas A&M AgriLife Research | News | Comments

Ibuprofen, a common over-the-counter drug worldwide, added to the healthy lifespan of yeast, worms and flies in a recent study. The treatment, given at doses comparable to the recommended human dose, added about 15 percent more to the species lives. In humans, that would be equivalent to another dozen or so years of healthy living.


Proteins Drive Cancer to Change

December 19, 2014 7:00 am | by MIT, Anne Trafton | News | Comments

A new study implicates a family of RNA-binding proteins in the regulation of cancer, particularly in a subtype of breast cancer. These proteins, known as Musashi proteins, can force cells into a state associated with increased proliferation.
