NIH-funded study observes virus-induced placental damage in monkeys.


Zika virus infection appears to affect oxygen delivery to the fetuses of pregnant monkeys, according to a small study funded by the National Institutes of Health. Researchers also observed a high degree of inflammation in the placenta and lining of the uterus, which can harm the fetal immune system and increase a newborn’s susceptibility to additional infections.Read full story

Insights may inform wound management techniques


Beneficial bacteria (link is external) on the skin of lab mice work with the animals’ immune systems to defend against disease-causing microbes and accelerate wound healing, according to new research from scientists at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.… Read full story

Memory Gene Goes Viral

Memory gene acts like a virus: Two independent teams of NIH-funded researchers discovered that the Arc gene can package its genetic material in a virus-like shell for delivery to nearby cells.NIH

NIH-funded research reveals novel method for transferring genetic material between neurons

Two independent teams of scientists from the University of Utah and the University of Massachusetts Medical School have discovered that a gene crucial for learning, called Arc, can send its genetic material from one neuron to another by employing a strategy commonly used by viruses.… Read full story

Researchers have discovered that genetic variations in the anatomy of the lungs could serve as indicators to help identify people who have low, but stable, lung function early in life, and those who are particularly at risk for chronic obstructive pulmonary disease (COPD) because of a smoke-induced decline in lung function.… Read full story
