Despite concerns that use of antipsychotic medications in treating young people has increased, use actually declined between 2006 and 2010 for children ages 12 and under, and increased for adolescents and young adults.
When egg cells form with an incorrect number of chromosomes--a problem that increases with age--the result is usually a miscarriage or a genetic disease such as Down syndrome.
Living with Type 1 diabetes requires constant monitoring of blood sugar levels and injecting insulin daily. Now scientists are reporting in the ACS journal Industrial & Engineering Chemistry Research the development of an implantable "artificial pancreas" that continuously measures a person's blood sugar, or glucose, level and can automatically release insulin as needed.
There may be far fewer galaxies further out in the universe then might be expected, according to a new study led by Michigan State University.
Among obese participants with type 2 diabetes mellitus, bariatric surgery with 2 years of a low-level lifestyle intervention resulted in more disease remission than did lifestyle intervention alone, according to a study published online by JAMA Surgery.

Extreme heat and precipitation events, which are expected to increase in frequency and intensity due to climate change, are associated with increased risk of Salmonella infections, according to a study led by researchers from the University of Maryland School of Public Health.
We've long known that beneath the scenic landscapes of Yellowstone National Park sleeps a supervolcano with a giant chamber of hot, partly molten rock below it.
Unwanted, intrusive visual memories are a core feature of stress- and trauma-related clinical disorders such as posttraumatic stress disorder (PTSD), but they can also crop up in everyday life.
