It's long been known that people living with HIV experience a loss of white matter in their brains. As opposed to "gray matter," which is composed of the cell bodies of neurons, white matter is made up of a fatty substance called myelin that coats neurons, offering protection and helping them transmit signals quickly and efficiently. A reduction in white matter is associated … [Read more...]

Tiny RNA that should attack coronavirus diminish with age, disease
A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report. MicroRNAs play a big role in our body in controlling gene expression, … [Read more...]
Everything is not fine: Kids can tell when parents suppress their stress
Stress is common in a family setting, especially when people are spending so much time together under stay-at-home measures meant to slow the spread of COVID-19. New research finds that parents suppressing feelings of stress around their kids can actually transmit those feelings to the children. In a paper published in Journal of Family Psychology, Sara Waters, assistant … [Read more...]

Study reveals how long COVID-19 remains infectious on cardboard, metal and plastic
The virus that causes COVID-19 remains for several hours to days on surfaces and in aerosols, a new study published in the New England Journal of Medicine found. The study suggests that people may acquire the coronavirus through the air and after touching contaminated objects. Scientists discovered the virus is detectable for up to three hours in aerosols, up to four hours … [Read more...]
Individual response to COVID-19 ‘as important’ as government action
How individuals respond to government advice on preventing the spread of COVID-19 will be at least as important, if not more important, than government action, according to a new commentary from researchers at the University of Oxford and Imperial College London in the UK, and Utrecht University and the National Institute for Public Health and the Environment in the … [Read more...]

Hookah Smoke may be Associated with Increased Risk of Blood Clots
For the first time, in a study conducted in mice, researchers found that tobacco smoke from a hookah caused blood to function abnormally and be more likely to clot and quickly form blood clots, which can increase the risk of heart attack or stroke, according to new research published today in the American Heart Association's journal Arteriosclerosis, Thrombosis and Vascular … [Read more...]
Data-driven definition of unhealthy yet pervasive ‘hyper-palatable’ foods
A popular U.S. brand of potato chips once promoted itself with the slogan, "betcha can't eat just one!" Maybe that's because potato chips, like so many foods in the American diet, can pack a mix of ingredients apt to light up people's brain-reward neural circuitry and overpower mechanisms that are supposed to signal when we've had enough to eat. Researchers call this … [Read more...]
Looking inside the body with indirect light
Light provides all our visual information, but it reaches our eyes in different ways. Direct light comes unperturbed, coming straight from the source, whereas indirect light bounces off different surfaces, such as walls or ceilings, before entering our eyes. Extracting information from these two pathways has significant implications in diagnostic imaging and other applications. … [Read more...]
Does herpes cause Alzheimer’s?
What causes Alzheimer's disease? The answer could be right under our noses, says leading expert Professor Ruth Itzhaki. Her latest paper presents a lifetime of research evidence that the herpes virus responsible for cold sores can also cause Alzheimer's -- and new data which show antiviral drugs drastically reduce risk of senile dementia in patients with severe herpes … [Read more...]
