The best places to get accurate data about the world's ice shelves are not exactly the safest. Using satellites is not an accurate solution.

Researchers at the Georgia Institute of Technology and Pennsylvania State University have created specially designed robots called SnoMotes to traverse these potentially dangerous ice environments. The SnoMotes work as a team, autonomously collaborating among themselves to cover all the necessary ground to gather assigned scientific measurements. Data gathered by the Snomotes could give scientists a better understanding of the important dynamics that influence the stability of ice sheets.

More than 34 percent of American adults — about 72 million people — are obese or overweight, according to the Centers for Disease Control and Prevention. Scientists once hoped leptin, a hormone that sends the body chemical signals to stop eating and use stored energy, would be a weight-loss weapon.

Studies in thin animals looked promising but overweight animals and people didn’t respond the same way, likely because their bodies already overproduce leptin, causing them to develop resistance to the hormone.

But now University of Florida researchers say pairing leptin with just a minor amount of exercise seems to revive the hormone’s ability to fight fat again.

Clouds have typically posed a problem to scientists using satellites to observe the lowest part of the atmosphere because they block the satellite's ability to capture a clear, unobstructed view of Earth's surface.

But these "obstructions" are worth a closer look, as clouds and their characteristics actually serve a valuable role in Earth's climate. That closer look is now available by satellites comprising the Afternoon Constellation, or A-Train.

The five satellites – NASA's Aqua, Aura, CloudSat and CALIPSO and the French Space Agency's PARASOL – of the A-Train orbit only eight minutes apart and can be thought of as an extended satellite observatory, providing unprecedented information about clouds, aerosols and atmospheric composition.

- RECORD-1 trial shows RAD001 reduces risk of disease progression by 70%(1) - Exceptional interim results caused independent data monitoring committee to immediately share findings; patients on placebo offered RAD001(2) - RAD001 is first and only drug to date to show significant benefit after failure of approved therapies Sutent(R) (sunitinib), or Nexavar(R) (sorafenib),** with potential to address unmet medical need(1) - Once-daily oral RAD001 directly targets and continuously inhibits mTOR, a protein that controls tumour cell division and blood vessel growth(1)

New data show RAD001 (everolimus) may provide an important new treatment option for patients with advanced kidney cancer who have failed standard therapies.

- First and Only Treatment for Hunter Syndrome Now Approved in 40 Countries Worldwide

ESO's VLT has allowed astronomers to determine that WOH G64, a red supergiant star almost 2,000 times as large as our Sun located 163,000 light-years away in the Large Magellanic Cloud, weighs almost half of what was previously thought, thereby solving the mystery of its existence.

The behemoth star is found to be surrounded by a massive and thick torus of gas and dust, and is most likely experiencing unstable, violent mass loss.

"Previous estimates gave an initial mass of 40 times the mass of the Sun to WOH G64. But this was a real problem as it was way too cold, compared to what theoretical models predict for such a massive star. Its existence couldn't be explained," says Keiichi Ohnaka, who led the work on this object.

In 2001, the DNA sequence was published of a combination of persons. The DNA sequences of Jim Watson, discoverer of the DNA’s double helix structure, followed in 2007, and later the DNA of gene hunter Craig Venter. Recently the completion of the sequences of two Yoruba Africans was announced.

Now geneticists of Leiden University Medical Centre (LUMC) in The Netherlands have determined the first DNA sequence of a woman - and also the first European. This has been announced by the researchers this morning, during a special press conference at ‘Bessensap’, a yearly meeting of scientists and the press in the Netherlands.

Following in-depth analysis, the sequence will be made public, except incidental privacy-sensitive findings. The results will contribute to insights into human genetic diversity.
