Sewage surveillance is emerging as a powerful tool in the fight against antimicrobial resistance with the potential to protect vulnerable communities more effectively. Waterborne diseases affect over 7 million people in the U.S. every year, according to the Centers for Disease Control and Prevention, and cost our health care system over $3 billion. But they

Older people who are sleepy during the day or lack enthusiasm for activities due to sleep issues may be more likely to develop a syndrome that can lead to dementia, according to a new study. Older people who are sleepy during the day or lack enthusiasm for activities due to sleep issues may be more

New collaborative research has shown that using a fan in hot and humid weather reduces cardiac strain in older people, contradicting recommendations from the Centers of Disease Control and Prevention in the US. The study looked at the efficacy of different low-cost cooling strategies -- such as electric fans with and without spraying water on

New research suggests that adding a small amount of physical activity -- such as uphill walking or stair-climbing -- into your day may help to lower blood pressure.

Neuroscientists have discovered brain cells that form multiple coordinate systems to tell us 'where we are' in a sequence of behaviors. These cells can play out different sequences of actions, just like a music box can be configured to play different sequences of tones. The findings help us understand the algorithms used by the brain

Some patients being treated with immune checkpoint inhibitors, a type of cancer immunotherapy, develop a dangerous form of heart inflammation called myocarditis. Researchers have now uncovered the immune basis of this inflammation. The team identified changes in specific types of immune and stromal cells in the heart that underlie myocarditis and pinpointed factors in the

A new study of more than 1,000 adults, average age 33, found that meeting recommended physical activity guidelines isn't enough to counteract the 60-plus hours per week they spend sitting. To reduce heart disease risk and prevent accelerated aging, they need to sit less and work-out harder. Between long commutes, video conference-packed workdays and evenings

New research from reveals that the gut microbiome regulates the body's diurnal (day-night) rhythms in stress hormones. Depletion of gut microbiota results in disruptions in the brain's core circadian system, and is associated with altered stress hormone rhythms. The research highlights that gut microbes also regulates key stress-responding brain regions throughout the day. Using microbe

Children too young to know words like 'impossible' and 'improbable' nonetheless understand how possibility works, finds new work with two- and three-year-olds. The findings demonstrate that young children distinguish between improbable and impossible events, and learn significantly better after 'impossible' occurrences.

Researchers have uncovered new targets that could be the key to effectively treating glioblastoma, a lethal type of brain cancer. These targets were identified through a screen for genetic vulnerabilities in patient-derived cancer stem cells that represent the variability found in tumors. A team led by researchers at the University of Toronto has uncovered new

A new study changes the way we understand memory. Until now, memories have been explained by the activity of brain cells called neurons that respond to learning events and control memory recall. Neurologists have now expanded this theory by showing that non-neuronal cell types in the brain called astrocytes -- star-shaped cells -- also store

Along with defending against pathogens, the body's innate immune system helps to protect the stability of our genomes in unexpected ways -- ways that have important implications for the development of cancer, researchers are discovering.
