Tracking a gigantic sunspot across the Sun

An active region on the sun – an area of intense and complex magnetic fields – rotated into view on Oct. 18, 2014. Labeled AR 12192, it soon grew into the largest such region in 24 years, and fired off 10 sizable solar ...

Preventing the spread of repression

Scientists at the Friedrich Miescher Institute for Biomedical Research have identified a novel and unexpected regulatory activity of RNA at the edge of inactive chromosomal regions. In their publication in Nature Structural ...

Researchers identify cause of LED 'efficiency droop'

(Phys.org) —Rensselaer Polytechnic Institute researchers have identified the mechanism behind a plague of LED light bulbs: a flaw called "efficiency droop" that causes LEDs to lose up to 20 percent of their efficiency as ...

Micro transistor prototypes map the mind

(Phys.org) —To make better mind maps, a group of French scientists – building on prototypes developed at the Cornell NanoScale Science and Technology Facility (CNF) – have produced the world's first microscopic, organic ...

Sexually naive male mice, fathers respond differently to pups

Sexually naïve male mice respond differently to the chemical signals emitted by newborn pups than males that have mated and lived with pregnant females, according to a study published March 20 in The Journal of Neuroscience. ...

Computers 'taught' to ID regulating gene sequences

Johns Hopkins researchers have succeeded in teaching computers how to identify commonalities in DNA sequences known to regulate gene activity, and to then use those commonalities to predict other regulatory regions throughout ...

Controlling monkey brains and behavior with light

Researchers reporting online on July 26 in Current Biology have for the first time shown that they can control the behavior of monkeys by using pulses of blue light to very specifically activate particular brain cells. The ...
