Gay men have higher prevalence of eating disorders Gay and bisexual men may be at far higher risk for eating disorders than heterosexual men, as per a research studyconducted at Columbia University's Mailman School of Public Health. In the first population-based study of its kind, the scientists observed that gay and bisexual men have higher rates of eating disorders. The findings are published in the April 2007 issue of International Journal of Eating Disorders.

Protein Averts Cell SuicideResearchers have discovered how an unusual protein helps a cell bypass damage when making new DNA, thereby averting the cell's self-destruction.
But they also discovered that this protein, an enzyme called Dpo4, often makes errors when copying the genomic DNA sequence that later might cause the cell to become malignant.
