Missing link found between brain and immune system

In a discovery that overturns decades of textbook teaching, researchers at the University of Virginia School of Medicine have determined that the brain is directly connected to the immune system by vessels previously thought not to exist. That these vessels could have escaped detection when the lymphatic system has been so thoroughly mapped throughout the […]

Water not necessary for life?




The proteins that are vital to living creatures evolved in Earth’s water-rich environment and it was thought that water was vital for proteins to function, but some intriguing new findings from the University of Bristol (UK) challenge this dogma. Proteins consist of one or more polypeptides (chains of amino acids held together by peptide bonds) […]

The new research […]

Blood Could Be Integral Part Of Brain’s Processing Power




Scientists from the Massachusetts Institute of Technology believe that blood may actually help us think, in addition to its well-known role as the conveyor of fuel and oxygen to brain cells. “We hypothesize that blood actively modulates how neurons process information,” explained MIT’s Christopher Moore. Writing in the Journal of Neurophysiology, he noted that many […]

Menstrual Suppression OK, Say Doctors




Forty years ago, when birth control pills first hit the market, the recommended cycle was three weeks of active contraceptive pills followed by one week of placebos or no pills.
