Getting a Head Start on Autism


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 Quake That Shook Up Geology


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).

NASA Cassini Images May Reveal Birth of a Saturn Moon

Brought to you by Mr. Brennan


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.

Deadly H5N1 Bird Flu Needs Just 5 Mutations to Spread Easily in People


                                             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.

Small Microbes Almost Killed All Life on Earth, Study Suggests


      MIT professor of geophysics 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.

Possible New Target to Attack Flu Virus Identified

http://www.sciencedaily.com/releases/2014/04/140410153626.htm


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.

First 'Exomoon' Around Alien Planet Possibly Found



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.

A 'Wedding Ring' in Space


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.

Kangaroos Have 'Green' Farts


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.
