Researchers trace Parkinson’s damage in the heart
Heart attacks, diabetes and other disorders cause similar damage to nerves in the heart. Those patients and potential therapies could also benefit from the new visualization method, says Parkinson’s disease researcher Marina Emborg.
Ebola vaccine inches toward human clinical trials
The need for an Ebola vaccine is acute. Periodic outbreaks of the disease in sub-Saharan Africa, including an epidemic between 2013 and 2016, caused major loss of life and serious economic disruption.

Chimpanzee deaths in Uganda pinned on human cold virus
Scientists investigating an outbreak of respiratory disease in a community of wild chimpanzees in Uganda were surprised and dismayed to discover that rhinovirus C was killing healthy chimps.
Estrogen discovery could shed new light on fertility problems
Researchers have upended the traditional understanding of the hormonal cascade that leads to release of an egg from the ovaries.
New study shows how cells can be led down non-cancer path
As cells with a propensity for cancer break down food for energy, they reach a fork in the road: They can either continue energy production as healthy cells, or shift to the energy production profile of cancer cells.
New measure of insulin-making cells could gauge diabetes progression, treatment
Researchers at the University of Wisconsin-Madison have developed a new measurement for the volume and activity of beta cells, the source of the sugar-regulating hormone insulin.
Stem cell advance brings bioengineered arteries closer to reality
New techniques have produced, for the first time, functional arterial cells at both the quality and scale to be relevant for disease modeling and clinical application.
Old bones lead to new strategy for drug delivery
An engineering team has developed a new way to seed biomedical devices with agents that promote tissue growth and healing.
