Researchers found that a set of genetic variants could identify people at risk for coronary heart disease and who would benefit most from statin therapy.
Physical activity may help improve movement problems linked to brain lesions in older people. The results highlight the importance of an active lifestyle for older adults.
Scientists used a powerful new technique to systematically turn off all the genes in mouse lung cancer cells and test how they affect tumor growth and metastasis.

Falling air pollution levels in Southern California were associated with improvements in children’s lung function during a critical period of growth and development.
A study in mice suggests that common food additives called emulsifiers might play a role in the increasing incidence of obesity and chronic inflammatory bowel disease.
Genetic switches called super-enhancers help regulate the human immune system. The finding will inform research into autoimmune disorders such as rheumatoid arthritis.

Infants who regularly consumed peanut products from infancy to age 5 proved less likely to become allergic to peanuts.
More than 100 reference human epigenomes from a broad range of cell and tissue types revealed epigenomic factors associated with age, sex, tissue type, and various diseases.
Scientists created a compound that could potentially lead to a long-lasting method of HIV prevention and treatment.

Daily iron supplements can improve the health of blood donors and reduce the number whose donations need to be deferred.
The first person to be documented with WHIM syndrome was spontaneously cured by a cellular event normally considered catastrophic.
Researchers created a detailed map of bacterial diversity throughout New York City. The findings could aid surveillance of disease, bioterrorism threats, and health management.

A large number of people may combine alcoholic beverages with prescription medications known to interact with alcohol, an analysis suggests.
Researchers revealed one type of neuron that promotes thirst and another that suppresses it. The findings give insight into how the brain controls fluid levels in the body.
Bacteria were altered to make them unable to survive without a synthetic nutrient. This technique may prevent genetically modified bacteria from surviving in the wild.

By analyzing twins, researchers determined that most of the variability in the immune system is due to environmental factors, rather than genes.
A comprehensive landscape of genomic alterations in head and neck cancers will provide important new clues for future research and treatment directions.
Over time, rats recall a fearful memory by a separate brain pathway than the one first used to recall it. The discovery may provide clues to improved treatments for anxiety disorders.
