However, there are so many other things in our everyday lives — from our environment to our diet — that […]
Stepping patterns become slower and more variable if a person is uncomfortable with their surroundings, researchers have found. Scientists at the University of Bristol have discovered that people who felt more at ease in urban environments had as regular stepping patterns as folk who felt relaxed walking in nature. The findings, published in PLOS ONE, […]
New research has discovered that the strength of the connection between our brain and internal organs is linked to how we feel about our appearance. Published in the journal Cortex, the study is the first to investigate, and first to identify, the association between body image and the brain’s processing of internal signals that occur […]
A 2015 paper on a chicken virus showed vaccines could enable more deadly variants to spread—in chickens. But that outcome is rare. Only a minority of human and animal vaccines have affected the evolution of a virus. In most of those cases, evolution didn’t increase the severity of the pathogen. The hypothetical possibility that the […]
A genetic ancestry test (GAT) can not only unearth deep family secrets, it also can change how people self-identify their race on surveys. A new study by Stanford sociologists delves into how such changes could affect data that demographers use to measure population shifts and monitor racial inequalities. Aliya Saperstein, associate professor of sociology, and […]
Most people dream of early retirement, but surprising research has shown that shortening your career could be detrimental to your health. A study published in MedPage Today found that early retirement brings a higher risk of mortality, especially for people younger than 60 or male. Another study found that retirees with health problems lived longer […]
Human papillomavirus (HPV) can infect the mouth and throat to cause cancers of the oropharynx. A new study published early online in Cancer, a peer-reviewed journal of the American Cancer Society, has found that having more than 10 prior oral sex partners was associated with a 4.3-times greater likelihood of having HPV-related oropharyngeal cancer. The […]
WEDNESDAY, Dec. 2, 2020 — Levels of some small molecules called metabolites in the body may affect your risk of stroke, a new analysis suggests. Metabolites come from the food people eat, and they cause chemical processes within the bodies and microbes. An analysis of previously published studies found that the levels of 10 of […]
Does weather affect the spread of the coronavirus outside? Not really. The World Health Organization says the virus can be transmitted in any kind of weather and that there is no reason to believe that cold weather can kill it. The U.N. health agency says the virus is mainly spread between people. Rain and snow […]
During pregnancy in mice, the billions of bacteria and other microbes that live in a mother’s intestines regulate key metabolites, small molecules that are important for healthy fetal brain development, UCLA biologists report Sept. 23 in the journal Nature. While the maternal gut microbiota has been associated with abnormalities in the brain function and behavior […]
