Treatment Helps With Kidney Transplants About 1 in 3 candidates for kidney transplantation has a condition that causes their bodies to immediately reject transplanted organs. A new treatment promises to boost transplant success by “desensitizing” these patients to foreign human tissue. The treatment could lead to thousands more kidney transplants every year. For patients with […]

Gene Defect Linked to Disfiguring Disorder Scientists have identified the faulty gene responsible for Proteus syndrome, a rare disorder marked by uncontrolled growth of certain body tissues and organs. The finding could have implications for developing targeted therapies for the condition. It may also offer insights into cancer progression and treatment. Jordan, 16, from Bexhill, […]

Serotonin Helps Control Body Temperature and Breathing Serotonin-producing cells in the mouse brain play an essential role in maintaining a healthy balance in body temperature and breathing. The finding might help to shed light on sudden infant death syndrome (SIDS) and other disorders linked to abnormal serotonin activity. Serotonin is a neurotransmitter, or chemical messenger, […]

Updates to Family History May Improve Cancer Screening Family histories of cancer can change significantly between ages 30 and 50 and may warrant earlier or more intense cancer screening. The new findings suggest that doctors should regularly update the family health histories of middle-aged patients. Your family’s medical history is one of the best tools […]

Placebo Improves Asthma Symptoms, But Not Lung Function Placebo treatment may make asthma patients feel better but not actually lessen disease, according to a new study. The finding helps clarify the benefits and limitations of the placebo effect. It may also influence how doctors measure successful treatment. The placebo effect is a well-known phenomenon in […]

The Benefits of Being a Beta Male In male baboons, a higher social rank generally brings higher testosterone and lower stress hormone levels. But according to a new study, the highest-ranked (alpha) males have higher stress levels than the second-ranking (beta) males. The finding suggests that life at the very top can be more costly […]
Artificial Human Liver May Speed Drug Development Scientists have devised an artificial human liver that, when implanted in mice, continues to make human proteins and break down certain drugs as the human liver would. The technique could lead to more accurate testing of potential medications. A scanning electron micrograph reveals the complexities of mouse liver […]

A Way to Burn More Calories? Scientists have uncovered a pathway in mice that allows white fat—a contributor to obesity and type 2 diabetes—to burn calories as if it were brown fat or muscle. The body uses white fat to store extra energy. Too much white fat (obesity) increases the risk of type 2 diabetes […]
