Just as people’s joints can get stiff as they age and make it harder for them to move around, hair follicle stem cells also get stiff, making it harder for them to grow hair, reports a new Northwestern Medicine study. But if the hair follicle’s stem cells are softened, they are more likely to produce […]
Collaborating researchers from the University of Pennsylvania School of Dental Medicine and the Adams School of Dentistry and Gillings School of Global Public Health at the University of North Carolina have discovered that a bacterial species called Selenomonas sputigena can have a major role in causing tooth decay. Scientists have long considered another bacterial species, […]
Keeping track of everything you eat and drink in a day is a tedious task that is tough to keep up with over time. Unfortunately, dutiful tracking is a vital component for successful weight loss, however, a new study in Obesity finds that perfect tracking is not needed to achieve significant weight loss. Researchers tracked […]
Researchers have discovered that a bacterial species called Selenomonas sputigena can have a major role in causing tooth decay. Scientists have long considered another bacterial species, the plaque-forming, acid-making Streptococcus mutans, as the principal cause of tooth decay. However, in the study, S. sputigena, previously associated only with gum disease, can work as a key […]
A team of scientists from the Institute for Research in Biomedicine (IRB Barcelona) in collaboration with the National Center for Genomic Analysis (CNAG) has discovered that IL-17 protein plays a central role in skin ageing. The study, which was led by Dr. Guiomar Solanas, Dr. Salvador Aznar Benitah, both at IRB Barcelona, and Dr. Holger […]
A deficiency of taurine — a nutrient produced in the body and found in many foods — is a driver of aging in animals, according to a new study led by Columbia researchers and involving dozens of aging researchers around the world. The same study also found that taurine supplements can slow down the aging […]
Researchers at the Department of Biology, University of Copenhagen, have now contributed to solving this problem for a specific gene called GCK. Rasmus Hartmann-Petersen, Professor at the Department of Biology, explains:– “The GCK gene, which codes for the enzyme glucokinase, regulates the secretion of insulin in the pancreas. GCK gene variants can therefore cause a […]
Although ultra-processed foods are convenient, low cost, quick to prepare or ready-to-eat, these industrial formulations of processed food substances contain little or no whole food. They result from extensive ‘physical, biological, and chemical processes’ that create food products that are deficient in original and natural food. Researchers explored a nationally representative sample of the United […]
Acting as a team, twin stem cells activate the immune system to suppress tumor growth and prolong survival in representative preclinical models. Overall survival for patients with melanoma that has spread to the brain is only four to six months. Immunotherapies, which harness the power of the immune system to attack cancer cells, have garnered […]
A typical human cell is metabolically active, roaring with chemical reactions that convert nutrients into energy and useful products that sustain life. These reactions also create reactive oxygen species, dangerous by-products like hydrogen peroxide which damage the building blocks of DNA in the same way oxygen and water corrode metal and form rust. Just how […]
