PHILADELPHIA - Researchers are getting closer to learning how to turn white fat cells into brown fat cells, in a process called "beiging," to bring down blood sugar levels and fight diabetes. The team, led by Joseph Baur, PhD, an assistant professor of Physiology in the Perelman School of Medicine at the University of Pennsylvania published their findings this month in the journal Diabetes.

For the first time astronomers were able to analyse the atmosphere of an exoplanet in the class known as super-Earths. Using data gathered with the NASA/ESA Hubble Space Telescope and new analysis techniques, the exoplanet 55 Cancri e is revealed to have a dry atmosphere without any indications of water vapour. The results, to be published in the Astrophysical Journal, indicate that the atmosphere consists mainly of hydrogen and helium.

The international team, led by scientists from University College London (UCL) in the UK, took observations of the nearby exoplanet 55 Cancri e, a super-Earth with a mass of eight Earth-masses [1]. It is located in the planetary system of 55 Cancri, a star about 40 light-years from Earth.

Western elites may embrace a vegetarian lifestyle but impoverished countries would happily trade places with them. Despite claims like it takes a gallon of gas to create a pound of beef being long debunked, activists continue to promote the notion that a vegetarian lifestyle is better for people and the environment.

Residents of Zambia know the organic, vegetarian lifestyle better than anyone in San Francisco environmental groups, and they have had quite enough. Now economists are catching on as well. A cow, a pair of oxen, or a herd of goats for a poor household dramatically improves their quality of life, finds a recent analysis. 

Cloud top temperatures in storms within Tropical Cyclone Uriah grew colder over the last couple of days, according to infrared imagery from NASA's Aqua satellite. That's an indication of stronger uplift in a tropical cyclone and a stronger storm. NASA-NOAA's Suomi NPP satellite saw the storm when it was struggling against wind shear, and two days later NASA's Aqua satellite saw Uriah reach hurricane-strength after the shear weakened.

Mothers of children with Autism Spectrum Disorder (ASD) often experience stress and suffer from sleep deprivation. Sacrifices almost always follow as they abandon professional careers and personal ambitions, believing that care for their children "comes first."

But is maternal abandonment of aspirations and interests really beneficial for the ASD child? A new Tel Aviv University study finds that a mother's positive attitude to involvement in everyday activities and a sense of competency in the performance of parental tasks accounts for a significant proportion of her children's successful participation in day-to-day activities.

Though wealthy elites and fad-chasing food activists have promoted the idea that salt is a killer, the science doesn't show that. Instead, links are correlational. Asia has always been held up as a standard for health but as their incidence of hypertension has risen, as many have blamed salt as they have a diet beyond what peasants could afford in the past.

On February 15th, 2013, as the approach of asteroid (367943) Duende was being closely monitored,  something far more alarming happened. Duende approached the Earth was expected to pass nearly 27,700 km above the Earth's surface, well inside the boundaries of the ring of geosynchronous satellites but nearly perpendicular to it, but then the Chelyabinsk superbolide entry occurred, followed by the explosion and the fall of the large meteorite in the Russian Lake Chebarkul. 

It caused damage to hundreds of buildings and injuries to nearly 1,500 people. 

Researchers have identified a gene which can be used to predict how susceptible a young person is to the mind-altering effects of smoking marijuana, an increasing concern as the cultural movement shifts toward legalization.  Around one percent of cannabis users develop psychosis. It is known that smoking cannabis daily doubles an individual's risk of developing a psychotic disorder, but it has been difficult to establish who is most vulnerable.  

In 2012, a group of UCLA researchers set out to mine thousands of electronic health records for a more accurate and less expensive way to identify people who have undiagnosed Type 2 diabetes. The researchers got much more than they bargained for.

Not only did they develop a screening algorithm with the potential to vastly increase the number of correct diagnoses of the disease by refining the pool of candidates who are put forward for screening; they also uncovered several previously unknown risk factors for diabetes, including a history of sexual and gender identity disorders, intestinal infections and a category of illnesses that includes such sexually transmitted diseases as chlamydia.

The findings appear February 16 in the Journal of Biomedical Informatics.
