The film "Avatar" isn't the only 3-D blockbuster making a splash this winter. A team of Houston scientists this week unveiled a new technique for growing 3-D cell cultures, a technological leap from the flat petri dish that could save millions of dollars in drug-testing costs. The research is reported in Nature Nanotechnology...

US researchers have developed a new powerful microscopy technique and used it to show proteins killing bacteria in real time, thus revealing the deadly workings of antimicrobial peptides (AMPs), naturally occurring proteins that scientists are pursuing as a new approach to treating bacterial infections...

In a new study published in Biological Psychiatry, by Elsevier, researchers have related the findings that are emerging from PET-PIB imaging to changes in the function of brain circuits. The emergence of multiple new brain imaging technologies and the combined application of these new approaches is helping to create new insights into aging and Alzheimer's disease...
