Researchers at McMaster University have peered into the most intimate moments of sexually active women and men across Canada to ask if they're using condoms, all in an effort to gather data that could inform decisions around public health and sex education.

What's emerged is a blended picture of trends in the use of condoms to prevent sexually transmitted infections and pregnancy.

CHICAGO--February 20, 2020--Patients who have taken antidepressants for years should consider coming off the medication. However, researchers say they will likely face difficult and even dangerous withdrawal symptoms due to a physical dependence.

The best process is to follow a tapering schedule while consulting with a physician, according to research in The Journal of the American Osteopathic Association. Stopping medication outright is almost never advisable.

RIVERSIDE, Calif. -- Researchers at the University of California, Riverside, have completed a cross-sectional human study that compares biomarkers and metal concentrations in the urine of e-cigarette users, nonsmokers, and cigarette smokers.

They found that the biomarkers, which reflect exposure, effect, and potential harm, are both elevated in e-cigarette users compared to the other groups and linked to metal exposure and oxidative DNA damage.

AURORA, Colo. (Feb. 19, 2020) - A novel, four-week parenting rotation designed for pediatric residents has dramatically increased the amount of time resident parents can spend at home with their babies, according to a study by researchers at the University of Colorado Anschutz Medical Campus.

The elective, created in 2010 by physicians at the University of Colorado School of Medicine, was set up to address the lack of maternity leave for doctors in residency programs, a time when many get pregnant.

Using mindfulness training as a cognitive enhancement tool, two new studies from University of Miami researchers show that firefighters and soldiers who participated in short-form mindfulness training programs tailored for their respective professional contexts, benefited from improved attention and resilience. These benefits, the researchers argue, better equip these professionals to manage stressors on the frontlines of their high-demand occupations.

A study of teenage girls' selfie-taking behaviors found that taking and sharing selfies on social media is not linked to poor body image or appearance concerns.

However, when adolescent girls spend too much time agonizing over which photo of themselves to post, or rely heavily on editing apps to alter their images, there may be cause for concern.

On April 13, 2029, an icy chunk of space rock, wider than the Eiffel Tower is tall, will streak by Earth at 30 kilometers per second, grazing the planet's sphere of geostationary satellites. It will be the closest approach by one of the largest asteroids crossing Earth's orbit in the next decade.

Exposure in the womb to phthalates, a group of endocrine-disrupting chemicals present in cosmetics and other common household products, was associated with autistic traits in boys, ages 3 and 4, but not in girls, according to a new study led by a University of Massachusetts Amherst environmental epidemiologist.

Fertility doctors in France have announced the birth of the first baby to be born to a cancer patient from an immature egg that was matured in the laboratory, frozen, then thawed and fertilised five years later.

Let's assume we are dancing on a meadow, quickly spinning about our own axis. At some point we hop on a rotating carousel. We may end up hurting ourselves when both rotations add up and angular momentum is transferred. Are similar phenomena also present in quantum mechanical systems?

An auditory illusion thought to synchronize brain waves and alter mood is no more effective than other sounds, according to research in adults recently published in eNeuro. The effect reported in other studies might be a placebo but could still have helpful effects for some people.

Accountable Care Organizations -- or ACOs -- formed for the first time in 2011, designed to combat rising medical costs and provide more coordinated care to Medicare patients. But the savings have been inconsistent nationwide.

A new Portland State University study looked at what's driving those inconsistencies and what ACOs might do to resolve the issue. The study was published in the February issue of Health Affairs by OHSU-PSU School of Public Health Assistant Professor Sunny Lin.

In 1988, a 6.9 magnitude earthquake struck near the northern Armenian city of Spitak. The temblor destroyed cities and is estimated to have killed between 25,000 and 35,000 people, many of whom were schoolchildren.

The latest findings from a long-term, UCLA-led study reveal that children who survived the quake and received psychotherapy soon after have experienced health benefits into adulthood.

BOSTON - E-cigarettes have been sold for more than a decade, seemingly without incident, but in the summer of 2019 serious lung injuries began appearing among some e-cigarette users -- especially adolescents and young adults. By last January of 2020, the Centers for Disease Control and Prevention reported more than 2,700 hospitalizations for EVALI, or e-cigarette or vaping product use-associated lung injury, and confirmed 60 deaths in 27 states with more under investigation.

The Chinese puzzle ball is an ornate decorative artwork consisting of several concentric shells that move independently of each other. In the recent decade, Chinese scientists provided a universal method for the fabrication of a conceptually similar micronanoscale structure, called the hollow multishell structure (HoMS).
