Occupational exposure to formaldehyde in Chinese men may be linked to reduced fertility, reports a new article.

Medical researchers have defined the structure of a key part of the human obesity receptor -- an essential factor in the regulation of body fat -- which could help provide new treatments for the complications of obesity and anorexia.

Scientists report that male pseudoscorpions treated with the antibiotic tetracycline suffer significantly reduced sperm viability and pass this toxic effect on to their untreated sons. They suggest that a similar effect could occur in humans and other species.

Researchers have discovered small molecules that kill cancer cells caused by infection with human papillomavirus. Their results, in both cell and mouse models, demonstrate that the small molecule inhibitors protect a tumor-suppressing protein targeted by viral proteins, thus killing the infected tumor cells. The researchers believe that, with further testing and refinement, their inhibitors could provide a therapeutic for HPV-caused tumors, such as those seen in cervical cancer.

Scientists are reporting that the mucus lining the stomachs of pigs could be a long-sought, abundant source of "mucins" being considered for use as broad-spectrum anti-viral agents to supplement baby formula and for use in personal hygiene and other consumer products to protect against a range of viral infections.

A single gene that promotes initial development of the most common form of lung cancer and its lethal metastases has been identified.

Oregano, the common pizza and pasta seasoning herb, has long been known to possess a variety of beneficial health effects, but a new study indicates that an ingredient of this spice could potentially be used to treat prostate cancer, the second leading cause of cancer death in American men.

Scientists believe that two forms of vitamin E – gamma and delta-tocopherols – found in soybean, canola and corn oils as well as nuts do prevent colon, lung, breast and prostate cancers while the alpha tocopherols found in vitamin E supplements provide no such protection.

Preliminary data hint at how extracts from the tree, abundant in tropical and subtropical areas, may stop the virus from multiplying.

While the artist’s haunting self-portraits focus largely on anatomy and failed reproduction attempts, relatively little attention has been paid to her own body and infertility.
