Researchers report 63 percent of breast milk samples from mothers using marijuana contained traces of the drug.

Long-term use of coal, wood, or charcoal for cooking is associated with an increased risk of death from cardiovascular disease, according to a study presented today at ESC Congress 2018(1).

Suicide rates are likely to rise as the earth warms, according to new research published July 23 in Nature Climate Change. The study, led by Stanford economist Marshall Burke, finds that projected temperature increases through 2050 could lead to an additional 21,000 suicides in the United States and Mexico.

There's increasing consensus that drinking coffee is mostly good for you. In addition to the physical boost it delivers, coffee also appears to lessen our risk of heart disease, diabetes, some cancers, dementia and Alzheimer's disease. It has been demonstrated, in studies, to improve both problem-solving and decision-making. And coffee may even help us live longer, according to a just-released British study involving nearly 500,000 adults in the U.K.

Physician burnout is at least equally responsible for medical errors as unsafe medical workplace conditions, if not more so, according to a study led by researchers at the Stanford University School of Medicine.

New research found that being in a bad mood can help some people’s executive functioning, such as their ability to focus attention, manage time and prioritize tasks. The same study found that a good mood has a negative effect on it in some cases.

A team of international researchers has found a link between seasonal fluctuations in sea level to a long-time phenomenon — Rossby Waves. And this connection may lead to a new tool to help coastal communities, such as Miami, better anticipate and mitigate “nuisance flooding” impacts.

A new study from the University of Waterloo highlights a low level of awareness among youth around the proper precautions they need to take when it comes to handling food.

Humans can perform a vast array of mental operations and adjust their behavioral responses based on external instructions and internal beliefs. For example, to tap your feet to a musical beat, your brain has to process the incoming sound and also use your internal knowledge of how the song goes.

MIT neuroscientists have now identified a strategy that the brain uses to rapidly select and flexibly perform different mental operations. To make this discovery, they applied a mathematical framework known as dynamical systems analysis to understand the logic that governs the evolution of neural activity across large populations of neurons.

If you’re up there in age and feel like you can coast as a couch potato, you may want to reconsider. A new study suggests, for the first time in women over age 70, that working up a sweat can reduce the influence one’s genes have on obesity.
