The way people with autism see and process the body language of others could be preventing them from gaging people's feelings, according to new research.

A new oral vaccine against sylvatic plague is showing significant promise in the laboratory as a way to protect prairie dogs and may eventually protect endangered black-footed ferrets who now get the disease by eating infected prairie dogs, according to new results. Sylvatic plague is an infectious bacterial disease usually transmitted from animal to animal by fleas.

In its fight against an intruding virus, an enzyme in our immune system may sense certain types of viral RNA pairs, according to scientists.

Data collected during two close flybys of Saturn's moon Enceladus by NASA's Cassini spacecraft add more fuel to the fire about the Saturnian ice world containing sub-surface liquid water.

Activation of two different kinds of neurons is necessary for appetitive and aversive memory recall in crickets.

Creating a Second Life avatar, or virtual representation of oneself, that is thin and physically fit may encourage individuals to become healthier and more physically fit in their real lives, according to a new study.

New research has determined an immune mechanism responsible for graft failure in a mouse model of in utero blood cell transplantation, a procedure that could be used to treat human congenital blood disorders. As fetal immune cells were triggered to eliminate the transplanted blood cells by immune molecules obtained from the mother's breast milk, the authors suggest that it should be possible to develop approaches to insure this approach is successful in the clinic.

Scientists have combined a trio of shots taken seconds apart through different colored filters to create a special-effects portrait of a moving dust devil on Mars.
