Volunteers who take part in conservation efforts may do it more for themselves than the wildlife they are trying to protect, a University of Alberta case study shows.

A study of purple martin landlords—those who keep and monitor special birdhouses on their land—revealed that they were more motivated to take part in the conservation project for egoistic rather than altruistic reasons.

B cells, the source of damaging autoantibodies, have long been thought to depend upon T cells for their activation and were not considered important in the initiation of autoimmune diseases like lupus or rheumatoid arthritis.

In the Aug. 7 online issue of the journal of Immunity, Yale University researchers turn this paradigm on its head by showing that in systemic autoimmune diseases B cells can be activated the absence of T cells.

The study suggests new ways to intervene in the immune system's chronic attacks on the body's own tissue.

Geneva, 7 August 2008. CERN has today announced that the first attempt to circulate a beam in the Large Hadron Collider (LHC) will be made on 10 September.

Approximately 15 professors, deans and other professionals in the computing sciences from the People's Republic of China came to Arlington, Va. last month for a summit with their U.S. counterparts. The one-day meeting gave participants the chance to discuss challenges and opportunities facing computing scholars from both sides of the Pacific, and it reflected the growing level of cooperation between the academic research communities in both countries.

Chili peppers can do more than just make you feel hot, reports a study in the August 1 Journal of Biological Chemistry; the active chemical in peppers can directly induce thermogenesis, the process by which cells convert energy into heat.

Capsaicin is the chemical in chili peppers that contributes to their spiciness; CPS stimulates a receptor found in sensory neurons, creating the heat sensation and subsequent reactions like redness and sweating.
