Men over 50 have an increased risk of developing melanoma but most take few sun exposure precautions, according to a new survey by the American Academy of Dermatology (AAD). The survey found:

A new study by researchers at Harvard Medical School and Oxford University finds that obesity is just as common among the homeless as it is among the general population. The authors say that while previously being underweight was a common problem for the homeless, rates of obesity are climbing.
