How cancer cells escape crowded tumors
Like people, cells in the human body protect their personal space. They seem to know how much space they need, and if it gets too tight, most cells prefer to break free. The mechanism enabling cells to evade crowded environments appears to involve an unusual player—the cell nucleus.

Mouthwashes, oral rinses may inactivate human coronaviruses
Certain oral antiseptics and mouthwashes may have the ability to inactivate human coronaviruses, according to a Penn State College of Medicine research study. The results indicate that some of these products might be useful for reducing the viral load, or amount of virus, in the mouth after infection and may help to reduce the spread of SARS-CoV-2, the coronavirus that causes COVID-19.

Unhealthy behaviors trigger same brain responses as bad smells
Unhealthy behaviors trigger moral judgments that are similar to the basic emotions that contribute to our ability to survive. Two hypotheses are prevalent in the current scientific literature as to the identity of these emotions. Some researchers single out disgust, while others opt for pain. After developing a new approach to brain imaging, a research team from the University of Geneva (UNIGE) has come down on the side of disgust.

Exercise and nutrition regimen benefits physical, cognitive health
Researchers studied the effects of a 12-week exercise regimen on 148 active-duty Air Force airmen, half of whom also received a twice-daily nutrient beverage that included protein; the omega-3 fatty acid, DHA; lutein; phospholipids; vitamin D; B vitamins and other micronutrients; along with a muscle-promoting compound known as HMB.

Viral 'molecular scissor' is next COVID-19 drug target
American and Polish scientists, reporting Oct. 16 in the journal Science Advances, laid out a novel rationale for COVID-19 drug design—blocking a molecular "scissor" that the virus uses for virus production and to disable human proteins crucial to the immune response.

Study explains the process that exacerbates multiple sclerosis
People with multiple sclerosis (MS) gradually develop increasing functional impairment. Researchers at Karolinska Institutet have now found a possible explanation for the progressive course of the disease in mice and how it can be reversed. The study, which is published in Science Immunology, can prove valuable to future treatments.
