Researchers
at Vanderbilt University have designed Russell the robot (background).
It helps teach kids with autism, like this young boy, how to imitate
people and to interact with them.
The 1964 Great Alaska Quake caused several downtown areas of Anchorage to collapse. Here, that 11-foot (3.4 meter) drop — or subsidence — took a line of parked cars with it. Before the event, the sidewalk (left) had been as high as the street (far right).
The disturbance visible at the outer edge of Saturn's A ring in this image from NASA's Cassini spacecraft results from gravitational effects on ring particles by an object that may be replaying the birth process of icy moons. Cassini's narrow-angle camera recorded this view on April 15, 2013.
Health workers slaughtered
chickens at a wholesale poultry market in Hong Kong after three dead
chickens tested positive for "bird flu" in 2008. New research shows the
H5N1 flu virus could become easily transmissible among people if it
acquired just five genetic mutations.

Daniel Rothman stands next to part of the Xiakou formation in China. His
right hand rests on the layer that marks the time of the end-Permian
mass extinction event. Samples from this formation provided evidence for
large amounts of nickel that were spewed from volcanic activity at this
time, 252 million years ago.
This region of the NS1
viral protein binds the host protein DDX21, making it a potential target
for new antivirals against the influenza virusBetter antiviral drugs
could help the millions of people annually infected by flu, which kills
up to 500,000 people each year.

Researchers have detected the first potential "exomoon"
candidate, a moon orbiting an alien planet beyond our solar system.
This artist's illustration shows a possible view of the exomoon (left)
and a version of the system if it is actually a star and planet.
The expanding shell of gas shown here, called Abell 33, glows blue. It’s
the remnant of a dying star. The bright star that appears to sit on the
ring’s edge actually is nowhere near that shell of gas.
Microbes from the digestive tract of Eastern gray kangaroos (like the
one shown here with her joey) appear to explain the climate-friendly
flatulence of these animals.
Time lapse images from a high speed video shows how a fruit fly startled
by a looming shadow (off camera at the bottom right) performs a rapid
roll to bank away from the threat.
