The Starting Point Of Sun-Induced Skin Cancer Disovered By U Of Minnesota Researcher
According to a new study from the University of Minnesota, the earliest event in the development of sun-induced skin cancer may have been identified. The researchers found that the point of entry for skin cancer in response to sun exposure is in receptor molecules, molecular "hooks" on the outer surface of cells that also pull cannabinoid compounds found in marijuana out of the bloodstream.
Unique Experience With Civilian Bladder Trauma In Baghdad

Sitting Position Can Influence Risk Of Whiplash
Women run a three times greater risk than men of incurring a debilitating injury in a rear-end collision. This is partly due to differences between the sexes regarding sitting position. This has been shown by Bertil Jonsson at Umea University in Sweden.
