The structure and behavior of one of the most common proteins in our bodies has been resolved at a level of detail never before seen, thanks to new research performed at the Advanced Photon Source (APS) at the U.S. Department of Energy's Argonne National Laboratory.

Reduce, recycle and rebuild is as important to the most basic component of the human body, the cell, as it is to the environment.

Biomedical engineers are constantly coming up with ways to repair the human body, replacing defective and worn out parts with plastic, titanium, and ceramic substitutes - but the body does not always accept such substitutes seamlessly. Engineers from Brown and Purdue universities have found that simply changing the surface texture of implants can dramatically change the way cells colonize a wide variety of materials.

How is virus as for example HIV and bird flu able to make the cells within a human body work for the purpose of the virus? Researchers at the University of Copenhagen shed new light on this question.
