New gene therapy reprograms brain glial cells into neurons

A new gene therapy can turn certain brain glial cells into functioning neurons, which in turn could help repair the brain after a stroke or during neurological disorders like Alzheimer's or Parkinson’s diseases. In a series of studies in animals, a team of Penn State researchers led by Gong Chen […]

Violence in childhood leads to accelerated aging, study finds

Children who suffer abuse are more likely to age faster, while those who endure food insecurity or neglect may develop more slowly, according to new research led by the University of Washington. Violence, psychological or emotional abuse, deprivation and neglect — adverse childhood experiences — can affect both epigenetic, or […]

Key molecule responsible for learning and memory discovered

Unlike old dogs, old adults can indeed learn new tricks thanks to a protein molecule called netrin. Netrin is known to help set up the healthy nervous system in an infant’s developing brain by directing brain cells to make appropriate connections with other brain cells. New research conducted by scientists […]

Breast cancer cells become invasive by changing their identity

Researchers at Karolinska Institutet have identified a protein that determines the identity and invasive properties of breast cancer cells. The finding could lead to the development of new therapeutic and diagnostic strategies to target breast cancer invasion and metastasis. The study is published in the scientific journal Cancer Research. Cancer cell […]

Genes behind rapid deer antler growth, hardening identified

Stanford scientists and their collaborators have identified two key genes responsible for the rapid growth of deer antlers. They hope their insights will open the door to new approaches for treating bone diseases and fractures. Each spring, male deer sprout a new pair of antlers, which are essentially temporary external […]

Tiny nanostraws to deliver molecules to human cells safely and efficiently

Researchers can design the perfect molecule to edit a gene, treat cancer or guide the development of a stem cell, but none of that will matter in the end if they can’t get their molecule into the human cells they want to manipulate. The solution to that problem, described in […]

Predicting Risk of Major Coronary Events

Physicians can assess the risks of major coronary events in someone with diabetes reasonably well. Among those with diabetes, there are well-established indicators of risk such as weight, fasting levels of blood glucose and family history of the disease. Doctors also can consider more general measures of health such as […]

Breast milk, formula nurture similarities, differences in gut microbes

Infant formula is designed to mimic human breast milk not only in nutrients but also by nurturing a similar set of microbes in the digestive tract. Such microbes are indispensable in keeping us healthy: They crowd out disease-causing bacteria, influence our metabolism, and synthesize many vitamins and amino acids, the […]

Two apps target cancer risk in marginalized populations

Anne Teitelman believes the key to helping women stay healthy is to meet them where they are, to bring the personal, health-related care into their daily lives, not sequester it to a once- or twice-a-year visit to a nurse practitioner, doctor, or another care provider. So, the Penn Nursing researcher built two apps. The […]
