Barbara Wolfe and Jason Fletcher at the University of Wisconsin-Madison found children from lower income families have lower non-cognitive skills than children from richer families.
A well-known radio source has turned out not to be the galaxy it's been classified as for 20 years, but a surprisingly quiet black hole.…

Pictured is the vorticity at the surface of the ocean with red indicating clockwise rotation and blue indicating counter-clockwise rotation. Many small coherent eddies are visible. These eddies can rotate in either direction and can endure for a year or more. The sharp boundary between the broad red and blue regions is a fast-moving, meandering jet, analogous to the North Atlantic Gulf Stream. This was done by a numerical simulation of an idealized, wind-driven ocean basin calculated on massively parallel computers at the San Diego Supercomputer Center.

According to new research, ocean acidification makes it harder for sea snails to escape from their sea star predators. The findings suggest that by disturbing predator-prey interactions, ocean acidification could spur cascading consequences for food web systems in shoreline ecosystems.

They have provided physical evidence to a famous story of heroism during the Holocaust — known before only through the testimony of the 11 Jews who escaped a Lithuanian massacre site.
The Obama administration's controversial proposal to revise human research rules is flawed and should be scrapped, says a report from the National Academies of Sciences, Engineering, and Medicine.

Camera-equipped smartphones, laptops and other devices make it possible to share ideas and images with anyone, anywhere, often in real-time. But in our cameras-everywhere culture, the risks of accidentally leaking sensitive information are growing. Computer scientists at Duke University have developed software that helps prevent inadvertent disclosure of trade secrets and other restricted information within a camera's field of view by letting users specify what others can see.

There are reasons to be interested in the other worlds even if they couldn't possibly harbor life. The hot, rocky planets, for example, offer rare and precious clues to the character and evolution of the early Earth. Numerical models show these exoplanets can change their chemistry by vaporizing rock-forming elements in steam atmospheres that are then partially lost to space.
