Scarring molecule in fat tissue links obesity with distressed fat



Posted: 12 Jan 2018 10:29 AM PST


The fat of obese people becomes distressed, scarred and inflamed, which can make weight loss more difficult.


Expert unlocks mechanics of how snakes move in a straight line



Posted: 12 Jan 2018 10:29 AM PST


Biologists are studying the mechanics of snake movement to understand exactly how they can propel themselves forward like a train through a tunnel.


Black hole spin cranks-up radio volume

Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets.


Jet stream changes since 1960s linked to more extreme weather



Posted: 12 Jan 2018 06:12 AM PST


Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, wildfires and flooding. The new research is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By using tree rings, the researchers developed a historical look at the position of the North Atlantic jet back to 1725.


X-ray navigation could open up new frontiers for robotic spacecraft



Posted: 11 Jan 2018 07:39 PM PST


In a technology first, a team of engineers has demonstrated fully autonomous X-ray navigation in space -- a capability that could revolutionize NASA's ability in the future to pilot robotic spacecraft to the far reaches of the solar system and beyond.


Archeology of our Milky Way's ancient hub



Posted: 11 Jan 2018 01:29 PM PST


A new analysis of about 10,000 normal Sun-like stars in the Milky Way's bulge reveals that our galaxy’s hub is a dynamic environment of variously aged stars zipping around at different speeds.


Scientists make cells that enable the sense of touch



Posted: 11 Jan 2018 11:15 AM PST


Researchers have, for the first time, coaxed human stem cells to become sensory interneurons -- the cells that give us our sense of touch. The new protocol could be a step toward stem cell-based therapies to restore sensation in paralyzed people who have lost feeling in parts of their body.


A major step forward in organic electronics



Posted: 11 Jan 2018 08:53 AM PST


Researchers have developed the world's first complementary electrochemical logic circuits that can function stably for long periods in water. This is a highly significant breakthrough in the development of bioelectronics.


Enzyme shown to regulate inflammation and metabolism in fat tissue



Posted: 10 Jan 2018 07:04 PM PST


New research in mice and humans suggests that an enzyme called SNRK suppresses inflammation in obesity-related 'white fat' while increasing metabolism in heat-producing 'brown fat,' making SNRK an intriguing target in the battle against obesity.
