Quitting Smoking Benefits Health Despite Weight Gain
The benefits to cardiovascular health that are associated with quitting smoking aren’t blunted by the modest weight gain, a new study found. The research underscores the benefits of putting a stop to smoking.
How Resveratrol May Fight Aging
A new study gives insight into how resveratrol—found in grapes, red wine and nuts—may ward off certain age-related diseases. The findings could help in the development of new treatments.
Immune Cells Regulate Brain Development
Scientists discovered a new role for immune cells called microglia in the developing brain. The finding may reveal insights into neurodevelopmental disorders like autism and schizophrenia.

Common Genetic Factors Found in 5 Mental Disorders
Major mental disorders traditionally thought to be distinct share certain genetic glitches, according to a new study. The finding may point to better ways to diagnose and treat these conditions.
Biofilm Streamers Clog Medical Devices
Bacterial communities called biofilms can quickly clog medical devices such as stents and catheters by forming 3-dimensional streamers that block flow. The finding will inform future approaches to prevent these deadly clogs.
Shaking Out Clues to Autoimmune Disease
Researchers gained new insight into how an immune cell involved in several autoimmune disorders is regulated. Among their discoveries was a potential link with salt consumption.

The Genetics of Age-Related Macular Degeneration
Researchers identified several new regions of the human genome associated with age-related macular degeneration, a leading cause of blindness. The findings may eventually lead to new treatment and prevention approaches.
Understanding How We Speak
A new study revealed the patterns of brain activity that produce human speech. This research may one day lead to new methods for treating speech disorders.
Stem Cells Discovered in Deadly Parasitic Flatworms
The flatworms that cause the tropical disease schistosomiasis can survive inside infected people for decades. The discovery of the stem cells that may be responsible could now lay the groundwork for new strategies to treat the disease.

Youth Interventions Lower Prescription Drug Abuse
A new study found that middle school students in small towns and rural areas who received brief interventions had lower rates of prescription drug abuse into late adolescence and young adulthood.
Compound Induces Antitumor Protein
Researchers identified a small compound that can boost production of a known tumor-suppressing protein. The finding may improve on current approaches—now in clinical trials—that target this biological pathway.
Liver Stem Cells Discovered in Mice
Scientists successfully identified and grew a renewable population of liver stem cells for the first time, a new study reported. The findings could eventually lead to approaches that help rejuvenate damaged livers in people.
