Researchers have identified a new molecular pathway that appears to be involved in urinary protein loss, an early-stage kidney disease that affects 100 million people around the world, and is caused by a breakdown in the kidney's filtering structures. The pathway may be new target for cell-specific treatment of chronic kidney diseases.

Tufts University researchers have updated their Food Guide Pyramid for Older Adults to correspond with the USDA food pyramid, now known as MyPyramid. The Modified MyPyramid for Older Adults continues to emphasize a nutritionally adequate diet with specific emphasis on nutrient-dense food choices and the importance of fluid balance and regular physical activity for older adults.

Approximately one in every 500 to 650 baby boys is born with an extra X chromosome, a variation in their genetic code that until a few years ago was thought to result in infertility in all cases. However, this is no longer the case. New treatments for both children and adults are coming available.

Lack of adequate health insurance coverage is associated with less access to care and poorer outcomes for cancer patients. The uninsured are less likely to receive recommended cancer screening tests, are more likely to be diagnosed with later stage disease, and have lower survival rates than those with private insurance for several cancers.

Scientists have helped characterize a previously unknown link in the chain of biochemical reactions implicated in some forms of heart disease. The finding provides a new target for future drug therapies.

People suffering from chronic mental or physical disabilities should not resort to a dolphin "healing" experience, warn two researchers. The scientists have launched an educational campaign countering claims made by purveyors of what is known as dolphin-assisted therapy. While swimming with dolphins may be a fun, novel experience, no scientific evidence exists for any long-term benefit from 'dolphin-assisted therapy.'
