How sperm get a move on; discovery suggests new target for male contraception (February 5, 2010) -- Most of us probably think of sperm as rather active little cells, swimming with quick movements of their "tail" or flagella. But actually sperm's motility is in fact short lived. When in the male reproductive tract they have to rest easy, lest they wear themselves out prematurely and give up any chance of ever finding an egg. ... > full story
Melatonin precursor stimulates growth factor circuits in brain (February 5, 2010) -- N-acetylserotonin, the immediate precursor to melatonin, activates the same growth circuits in the brain as BDNF (brain-derived neurotrophic factor). The results have implications for how some antidepressants function and suggest that the molecules and pathways involved in mood regulation and circadian rhythms are intertwined. ... > full story
Haiti: International relief efforts remain fragmented, warn doctors (February 5, 2010) -- Despite the frightening regularity of humanitarian disasters like the earthquake in Haiti, international responses remain fragmented and must be improved, argue a group of trauma surgeons. ... > full story
Bacteria toxic to wound-treating maggots (February 5, 2010) -- Bacteria that infect chronic wounds can be deadly to maggot "bio-surgeons" used to treat the lesions, show researchers. The findings could lead to more effective treatment of wounds and the development of novel antibiotics. ... > full story
Study maps effects of acupuncture on the brain (February 5, 2010) -- New research about the effects of acupuncture on the brain may provide an understanding of the complex mechanisms of acupuncture and could lead to a wider acceptability of the treatment. ... > full story
