Does social media push teens to depression? New study says no

(HealthDay)—Time spent on Instagram, Snapchat or Facebook probably isn’t driving teenagers to depression, a new study contends. In fact, Canadian researchers found the relationship worked in the opposite direction—teenage girls who were already depressed tended to spend more time on social media, to try to feel better. These findings run counter to a series of […]

New drug brings unexpected hope in targeting cancer cells

An unexpected finding in pre-clinical platelet studies by Baker Institute researchers could provide a novel approach to targeting and destroying difficult-to-treat cancer cells, providing new therapeutic options for a range of cancers. This latest finding, published in the journal Theranostics, was discovered while studying activated platelets in the setting of heart disease and may now […]

Simple drug combination creates new neurons from neighboring cells

A simple drug cocktail that converts cells neighboring damaged neurons into functional new neurons could potentially be used to treat stroke, Alzheimer’s disease, and brain injuries. A team of researchers at Penn State identified a set of four, or even three, molecules that could convert glial cells—which normally provide support and insulation for neurons—into new […]

The interplay between relationships, stress, and sleep

A new Personal Relationships study documents how the quality of a person’s romantic relationship and the life stress he or she experiences at two key points in early adulthood (at age 23 and 32) are related to sleep quality and quantity in middle adulthood (at age 37). Investigators found that people who have positive relationship […]

In vitro grafts increase blood flow in infarcted rat hearts

Advances in stem cell research offer hope for treatments that could help patients regrow heart muscle tissue after heart attacks, a key to achieving more complete recovery. Scientists today report success in creating functional blood vessels in vitro for hearts of rats that had sustained a heart attack. The journal Nature Communications published the paper, […]

Functional insulin-producing cells grown in lab

UC San Francisco researchers have for the first time transformed human stem cells into mature insulin-producing cells, a major breakthrough in the effort to develop a cure for type 1 (T1) diabetes. Replacing these cells, which are lost in patients with T1 diabetes, has long been a dream of regenerative medicine, but until now scientists […]

Maternal glucose in pregnancy tied to child’s glucose outcomes

(HealthDay)—In utero exposure to higher levels of maternal glucose is associated with higher glucose levels and insulin resistance during childhood, according to a study published online Jan. 7 in Diabetes Care. Denise M. Scholtens, Ph.D., from the Northwestern University Feinberg School of Medicine in Chicago, and colleagues conducted follow-up with the Hyperglycemia and Adverse Pregnancy […]
