Current antidepressants usually take four to eight weeks to exert their effects. In a preliminary new study, a single intravenous dose of ketamine, a medication usually used in higher doses as an anesthetic, brought symptom relief to people with treatment-resistant depression in as little as two hours.
Young women who suffer from eating disorders such as anorexia, bulimia or binge eating disorder often develop their eating disorder around the time they begin college. A new study has found that an eight-week, Internet-based intervention may help college-age women at risk.
Human papillomaviruses (HPVs) are the most common sexually-transmitted infection in the U.S. A new study shows that carrageenan, a common cosmetic and food additive extracted from red algae, may be able to block HPV infections.

Chronic infection or inflammation of the middle ear, the area just behind the eardrum, is a common problem for children.

Almost half of those who get them will have three or more ear infections during their first three years.
New research shows that a chemical compound found in many air fresheners, toilet bowl cleaners, mothballs and other deodorizing products may be harmful to the lungs.
