The average Dane will gain a health benefit from substituting part of the red and processed meat in their diet with fish, according to calculations from the National Food Institute, Technical University of Denmark. Men over 50 and women of childbearing age in particular would benefit from such a change […]

According to researchers at Yale Cancer Center, a cancer drug thought to be of limited use possesses a superpower of sorts: It is able to stop certain cancer cells from repairing their DNA in order to survive. The study, published in the journal Science Translational Medicine, suggests that combining this drug, cediranib, […]

In its role as a unique orbiting laboratory, the International Space Station provides a broad range of equipment for conducting health and life sciences research. However, the equipment available for cellular and molecular biology is limited compared to capabilities found in laboratories on Earth. To address this limitation, the Canadian […]

By studying a rare form of dementia, researchers might have found a way to detect neurodegeneration before brain cells are lost for good. Earlier detection could provide therapeutic drug treatments a chance to work. Scientists might have found an early detection method for some forms of dementia, according to new […]

By injecting cells that support blood vessel growth into muscles depleted by inactivity, researchers say they are able to help restore muscle mass lost as a result of immobility. The research, conducted in adult mice, involved injections of cells called pericytes (PERRY-sites), which are known to promote blood vessel growth […]

Babies exposed to opioids while their mothers were pregnant with them may need special care even before they start to experience withdrawal symptoms, according to Penn State research. Researchers from Penn State College of Medicine found that as soon as 24 and 48 hours after birth, babies who were exposed […]

The human gut microbiome is a complex microbial ecosystem that plays an important role in our health. For example, these microbes — bacteria, viruses, fungi — help regulate metabolism, fend off infections, produce essential vitamins and break down dietary fiber. They may also be biomarkers of health and disease. A […]

By the time type 1 diabetes is diagnosed, most of the insulin-producing beta cells have already been destroyed. Now, using an innovative transplantation technique, researchers at Karolinska Institutet and University of Miami Miller School of Medicine have been able to intervene to save the beta cells in mice by discovering […]

The same sources thought to inflict oxidative stress on cells—pollution, diesel exhaust, smoking and obesity—also are associated with shorter telomeres, the protective tips on the ends of the chromosomal shoelace. A new study from the University of Pittsburgh, published in Molecular Cell, provides the first smoking gun evidence that oxidative […]

Though much of the human genome has been sequenced and assembled, scientists have hit road blocks trying to map unassembled regions of DNA that consist mostly of repetitive sequences. One of these regions, found in every cell, is the centromere. Researchers from the University of Rochester, along with their colleagues […]

These days, scientists can collect a few skin or blood cells, wipe out their identities, and reprogram them to become virtually any other kind of cell in the human body, from neurons to heart cells.   The journey from skin cell to another type of functional cell involves converting them into induced pluripotent […]

Obesity is a growing problem among toddlers, children and adolescents in the United States. Gaining weight and fat mass rapidly during the first six months of life is one risk factor that can lead to obesity in children. A University of Minnesota School of Public Health study, recently published in the journal Nutrients, […]
