Depression is a common risk for people who’ve lost vision from age-related macular degeneration. A type of therapy called behavior activation can cut this depression risk in half.
Men exposed to cool temperatures for a month had an increase in brown fat along with changes in metabolism. The finding hints at new approaches to conditions such as obesity and diabetes.
Scientists used a novel microchip-based method to isolate and grow tumor cells circulating in blood. The technique provides an important step toward personalizing cancer therapy.

The drug letrozole is more effective than standard therapy in increasing live births for women with polycystic ovary syndrome—a leading cause of female infertility.
Researchers identified DNA alterations that are involved in the development of lung adenocarcinoma. The findings may lead to more targeted therapies to treat this deadly cancer.
A new technique increased the time that rat livers can remain viable outside the body. If the approach succeeds in humans, it could aid organ transplant efforts.

Adults with severe sickle cell disease were successfully treated with a stem cell transplant approach that doesn't require extensive immune-suppressing drugs.
Low blood levels of lead were associated with increased behavioral and emotional problems in young children.
Researchers gained insights into a key protein involved in ciliopathies, a class of genetic disorders that arise from defects in hair-like extensions called cilia that are found on cells throughout the body.

Variations in a gene called APOC3 are associated with lower triglyceride levels and reduced risk of heart disease. The finding suggests new approaches to lower heart disease risk.
Research into the mechanisms that underlie our ability to remember events could yield insights into the memory problems that come with normal aging and dementia.
The structure of a protein that bacteria need to spread the genes for antibiotic resistance could spur the development of novel drugs to combat multidrug-resistant bacteria.

Hormone replacement therapy restored bone mineral density in women with primary ovarian insufficiency. The findings provide important treatment guidance.
Exposure to certain allergens and bacteria within the first year of life may protect children from wheezing and allergies. The study’s findings suggest asthma prevention strategies.
Researchers induced human stem cells to create a 3-D retina structure that responds to light. The finding may aid the study of eye diseases and could eventually lead to new therapies.
June 9, 2014
Researchers completed a draft map of the human proteome—the set of all proteins in the human body. The map will help advance studies of human health and disease.
A small dose of laser light activated stem cells in rat molars to generate dentin, a major component of teeth. The finding may lead to new approaches to tooth repair.
Scientists determined the structure of the NMDA receptor, an ion channel involved in many brain-related illnesses. The finding may aid in the development of future therapies.
