Researchers show that linguistic rules are processed in two phylogenetically different brain regions

Researchers found that simple language structures are processed in an area that is phylogenetically older, and which apes also possess. Complicated structures, by contrast, activate processes in a comparatively younger area which only exists in a more highly evolved species: humans.

Lifetime calorie restraint to prevent obesity is the most powerful way to reduce age-related health problems

University of South Florida researcher Barbara Hansen, PhD, will likely never be invited to talk about weight loss on Oprah.

Potential new drug for treating all forms of tuberculosis

An experimental tuberculosis drug may be effective against not only multi drug-resistant forms of the disease but could also be the first compound to treat the latent stage of infection as well. Researchers reported their results at the 2006 ASM Biodefense Research Meeting.

Interleukin-15 encourages CD8+ T cells to proliferate and reduces their tolerance to tumor antigens

Certain types of white blood cells assist the body in destroying cancerous tumors. Among these are CD8+ T cells. The T is for thymus, the gland near the base of the throat that both raises up and weeds out blood cells involved in immune responses.

New system for analyzing how drugs bind to proteins

Researchers at Florida State University's National High Magnetic Field Laboratory and Scripps Florida have developed and evaluated a robust new system for analyzing how drugs bind to proteins. This groundbreaking work could speed the delivery of potential new drugs and improve existing ones.
