When it comes to cardiovascular health, men and women have many of the same risks. After all, everyone faces the challenges of managing weight, blood pressure and cholesterol, among other factors — and heart disease remains the No. 1 cause of death in both sexes. But as women have unique heart […]

Using the power of computer science, physics and biology, scientists are attempting to mimic what took millions of years of evolution to refine: the creation of new proteins. The human body contains at least tens of thousands of different proteins, which act as workhorses driving many of the functions that […]

Chemotherapy drugs are lifesaving to cancer patients, but these toxic drugs are hazardous to the health care workers who come into contact with them. Despite the risks, many health care workers do not use recommended personal protective equipment such as gloves or gowns when handling chemotherapy. A study from the University […]

Analysis of genetic data from more than 94,000 individuals has revealed five new risk genes for Alzheimer’s disease, and confirmed 20 known others. An international team of researchers also reports for the first time that mutations in genes specific to tau, a hallmark protein of Alzheimer’s disease, may play an […]

The human body is made up of 30 to 40 million cells, a large and complex network of blood cells, neurons, and specialized cells that make up organs and tissues. Until now, figuring out which mechanisms control communication between them has proven a significant challenge for the field of cell […]

While virtually all cells in an animal’s body communicate with their neighbors in one way or another, many scientists thought that only neurons — the specialized cells that comprise much of the brain and nervous system — produce structures that allow signals to be delivered to specific locations over long […]

Princeton University researchers are gaining new insights into the causes and characteristics of diseases by harnessing machine learning to analyze molecular patterns across hundreds of diseases simultaneously. Demonstrating a new tool now available to researchers worldwide, the team of computer scientists and biologists has already uncovered and experimentally confirmed previously […]

U.S. rates of sexually transmitted infections (STI) are soaring to such an extent that public health officials are posting billboards that exhort sexual partners to use condoms. But who is championing male circumcision as a mechanism to protect women? Researchers, that’s who. A recent systematic review of 81 published studies and abstracts […]

In a paper published in the journal Nature, an international research team led by researchers at Karolinska Institutet in Sweden report that bone growth in mice takes place in accordance with the same principles as when new cells are constantly produced in blood, skin and other tissue. This contradicts the previous […]

People fall in love for many reasons — similar interests, physical attraction, and shared values among them. But if they marry and stay together, their long-term happiness may depend on their individual genes or those of their spouse, says a new study led by Yale School of Public Health researchers. […]

White-blooded Antarctic icefishes live with anemia, oversized hearts and low bone mineral density, traits that in people would normally signal disease. These adaptations, however, help the fish survive in cold water and may offer a window on human aging, says a UO biologist. That potential human health payoff comes with […]

Mathilde came into the world with chubby cheeks and a full head of auburn hair. But she was a very sick baby, and was immediately transferred on January 19, 2013 to the Neonatal Intensive Care Unit at the Montreal Children’s Hospital of the McGill University Health Centre (MCH-MUHC). By the […]

A single misbehaving protein – called TDP-43 – is behind 97 percent of amyotrophic lateral sclerosis (ALS) cases and 45 percent of frontotemporal dementia diagnoses. It also is found in 80 percent of chronic traumatic encephalopathy and 60 percent of Alzheimer’s disease cases. Now, University of Pittsburgh researchers have found a way […]

Rice University scientists say context rules dynamic mechanisms that turn cells into tissues. How cells in developing embryos communicate depends a great deal on context, according to scientists at Rice University. They found that a protein signaling pathway known as WNT and its interactions are far more dynamic than once thought as the response […]

A new biomaterial-based bone graft extender created by Vanderbilt and U.S. Army researchers has the potential to improve treatment of critical orthopedic conditions.
