Researchers previously identified a host of genetic risk factors that help explain why some veterans are especially susceptible to the debilitating symptoms of post-traumatic stress disorder (PTSD). Source: Nurture trumps nature in determining severity of PTSD symptoms

Tissues and cells in the human body are subjected to a constant push and pull – strained by other cells, blood pressure and fluid flow, to name a few. The type and direction of the force on a cell alters gene expression by stretching different regions of DNA, researchers in China found in a new […]

A class of compounds used for malaria treatment also kill the intestinal parasite Cryptosporidium, a leading cause of diarrheal disease and death in children that has no cure, a multi-institution collaboration of researchers found in a new study.

Whether flu or coronavirus, it can take several days for the body to ramp up an effective response to a viral infection. New research describes how different cells in the immune system work together, communicate, and – in the case of cells called neutrophils – bring about their own death to help fight off infections.

In September 2015, the US National Institutes of Health placed a funding moratorium on research that involves introducing human pluripotent stem cells into animal embryos. To assess attitudes on human-animal chimeric embryo research, investigators conducted a survey among 430 Americans. The results of the survey found that 82% of people are supportive of at least […]

Researchers have developed electronic blood vessels that can be actively tuned to address subtle changes in the body after implantation. The blood vessels — made of a metal-polymer conductor membrane that’s flexible and biodegradable — mimic natural blood vessels, were conductive in in vitro experiments, and were able to effectively replace key arteries in rabbits. […]
