Rats Show Empathy, Too A new study shows that empathy may drive rats to help each other. The finding gives insight into the biological roots of our urge to assist others in need. The model the researchers developed will also provide an opportunity for further study. Empathy motivates us to take action. We feel distressed […]
Less Medication Effective for Wheezing Preschoolers Children with recurrent wheezing who are in danger of developing asthma fared no better taking daily low doses of inhaled corticosteroid than taking higher doses only as needed. The children given treatment only as needed received far less total medication during the yearlong study. Asthma affects nearly 7 million […]

Prenatal Steroids Reduce Brain Injury in Preemies Some of the tiniest premature babies are more likely to survive and have less brain injury if their mothers receive prenatal steroids. The finding provides the first strong evidence that steroids can benefit preemies born as early as the 23rd week of pregnancy. Preterm babies are born before […]

Antibodies Protect Against HIV in Mice Researchers have devised a gene transfer technique in mice that, with a single injection, protects the immune cells that HIV targets. With further development, the approach may prove effective at helping to prevent HIV infection in people. Most vaccines work by triggering the immune system to produce antibodies to […]

Key Hearing Proteins Identified Researchers have found what appear to be 2 key components of the long-sought-after mechanotransduction channel in the inner ear—the place where sound waves are transformed into the electrical signals that the brain recognizes as sound. Sensory cells in the inner ear called hair cells are crucial for transforming sound into electrical […]
Wood Cooking Stoves Combat Pneumonia A new study found that wood-burning cooking stoves with chimneys lowered exposure to wood smoke from open cooking fires and reduced the rate of severe pneumonia by 30% in children less than 18 months of age. Childhood deaths from pneumonia are relatively uncommon in the United States. But the disease […]
Targeted Light Therapy Destroys Cancer Cells Scientists have developed a noninvasive technique that uses light to selectively wipe out cancerous cells in mice without harming surrounding tissue. With further research, this novel method might eventually be used to treat tumors in humans. A cluster of breast cancer cells. (Image by Annie Cavanagh. All rights reserved by […]

Stroke Risk Factors Linked to Cognitive Problems November 21, 2011 A new study found that high blood pressure and other known risk factors for stroke may also raise the risk of developing cognitive problems. The finding suggests that keeping blood pressure under control might help preserve cognitive health. Strokes occur when blood vessels that supply […]

Organ Transplants and Cancer Risk November 21, 2011 Organ transplant recipients have a high risk of developing 32 different types of cancer, according to a new study. Future research to understand why may lead to better strategies for preventing cancer among transplant recipients. In 2010, over 28,000 organ transplantations were performed in the U.S., including […]
Why Nicotine is a Gateway Drug A new study in mice shows how tobacco products could act as gateway drugs, opening the door to use of illicit drugs. Nicotine, the researchers found, makes the brain more susceptible to cocaine addiction. The finding suggests that lowering smoking rates in young people might help reduce cocaine abuse. […]
