Post ice-age extinctions of large mammals linked to humans, not climate change
Activation of brain region can change a monkey's choice
Artificially stimulating a brain region believed to play a key role in learning, reward and motivation induced monkeys to change which of two images they choose to look at. In experiments reported online ...

Study confirms highways are bad news for several bat species
Microchip-like technology allows single-cell analysis
A U.S. and Korean research team has developed a chip-like device that could be scaled up to sort and store hundreds of thousands of individual living cells in a matter of minutes. The system is similar to ...
Suddenly, the sun is eerily quiet: Where did the sunspots go?
The sun has gone quiet. Almost too quiet. A few weeks ago it was teeming with sunspots, as you would expect since we are supposed to be in the middle of solar maximum-the time in the sun's 11-year cycle when ...
Scientists track gene activity when honey bees do and don't eat honey
Many beekeepers feed their honey bees sucrose or high-fructose corn syrup when times are lean inside the hive. This practice has come under scrutiny, however, in response to colony collapse disorder, the ...
Magnetically controlled nanoparticles enhance stroke treatment
(Phys.org) —Researchers at the University of Georgia and their collaborators have developed a new technique to enhance stroke treatment that uses magnetically controlled nanomotors to rapidly transport ...
Study finds ocean bacteria follow predictable patterns of daily activity
We are all creatures of habit, and a new MIT study finds ocean bacteria are no exception.
Researchers harness a powerful new source of up-to-date information on economic activity
Researchers at the University of Michigan, University of California Berkeley, and Arizona State University have developed a new data infrastructure for measuring economic activity.
Unexpected stability and complexity in transcriptional enhancers' interactions
Contrary to what was thought, sequences of DNA called enhancers – which control a gene's output – find their targets long before they are activated during embryonic development, scientists at the European Molecular Biology ...
Engineering light-controlled proteins
(Phys.org) —A University of Wyoming professor has engineered proteins that can be activated by near-infrared light as a way to control biological activities in deep tissues of small mammals.
Space-tested robot inspires medicine and manufacturing uses
Humans doing difficult, repetitive tasks or those who need assistance with movement may soon get a helping hand - literally - thanks to robotic technology developed to serve astronauts in space.
Are ultra-luminous galaxies colliding?
(Phys.org) —ltra-luminous infrared galaxies ((ULIRGs) are galaxies whose luminosity exceeds that of a trillion suns, By way of comparison, our Milky Way galaxy has a typical modest luminosity of only about ...
