In late August, an instrument on the International Space Station, called NICER, spotted its brightest burst of X-ray radiation yet.
NICER, or the Neutron Star Interior Composition Explorer, studies X-rays that come from neutron stars, the super-dense remnants of some stars afte ...read more

It was a typical Japanese summer — hot, humid and cloudy — when archaeologists pulled a well-preserved, fossilized bird from the ground in 2013. Their find, announced this week in Nature Communications Biology, might change our idea of what adaptations were essential to the development of flight.

Some of
the biggest public health crises of the last few years can be traced back to
animals. HIV got its start as a virus in monkeys, and Ebola probably jumped to humans from other primates or fruit
bats. And there’s no points for guessing the animals we got bird flu and swine
flu from. But animal-borne diseases can start a lot closer to home. In fact,
there are a number we can pick up from our dogs and cats.

With the help of sound waves and a small plastic ball, researchers in the U.K. have designed a machine that generates truly 3D holographs.
The whole system is slightly smaller than a shoebox and makes simple images, like a butterfly or smiley face, that are less than an inch tall. Described in Nature, the device is one of the first 3D image generators that also responds to touch and produce ...read more
