Researchers at Johns Hopkins Medicine have shown that a type of echocardiogram, a common test to evaluate whether a person's heart is pumping properly, may be useful in predicting which patients with COVID-19 are most at risk of developing atrial fibrillation -- an irregular heartbeat that can increase a person's risk for heart failure and stroke, among other heart issues.

A new study led by WCS-India documents how a big cat deity worshipped by Indigenous Peoples facilitates coexistence between humans and leopards.

New paper by federal, state and academic researchers from across the United States offers guiding principles for deciding whether to resist, accept or direct ecosystem changes like sea-level rise, desertification and lake warming.

Researchers at Harvard's Wyss Institute and John A. Paulson School for Engineering and Applied Sciences (SEAS) have developed a biomaterial-based infection vaccine (ciVAX) approach as a solution that could be broadly applied to challenges in infection medicine.

Proactive, frequent rapid testing of all students for COVID-19 is more effective at preventing large transmission clusters in schools than measures that are only initiated when someone develops symptoms and then tests positive, Simon Fraser University researchers have found.

Feeling anxious about health, family or money is normal for most people--especially during the COVID-19 pandemic. But for those with anxiety disorders, these everyday worries tend to heighten even when there is little or no reason to be concerned.

For the first time, Princess Margaret researchers have mapped out where and how leukemia begins and develops in infants with Down syndrome in preclinical models, paving the way to potentially prevent this cancer in the future.

As tectonic plates slip past each other, the rivers that cross fault lines change shape. The shifting ground stretches the river channels until the water breaks its course and flows onto new paths. In a study published July 9 in Science, researchers at UC Santa Cruz created a model that helps predict this process. It provides broad context to how rivers and faults interact to shape the nearby topography.

The Large High Altitude Air Shower Observatory (LHAASO) has accurately measured the brightness over 3.5 orders of magnitude of the standard candle in high-energy astronomy, thus calibrating a new standard for ultra-high-energy (UHE) gamma-ray sources. The standard candle is the famous Crab Nebula, which evolved from the "guest star" recorded by the imperial astronomers of China's Song Dynasty.

In a small study of gymnasts with ulnar (elbow) collateral ligament injury, orthopedic sports medicine researchers found that the athletes can be treated successfully and can return to competition. The research was presented at the American Orthopedic Medicine Society- Arthroscopy Association of North America Combined 2021 Annual Meeting.

A new study shows that individuals with bipolar disorder who are exposed to significant trauma may be at greater risk for suicide death, suggesting that a diagnosis of post-traumatic stress disorder (PTSD) or genetic predisposition to PTSD could be important factors in suicide prevention.

This research provides a broad perspective on the use of PVBs in Ontario, and on the use of nerve blocking treatments in general. There has been a concern for several years about the over use of these procedures; however, this is the first study to systematically document the impact on health care utilization and opioid use.

People who get type 2 diabetes need to gain control of their blood-sugar levels -- fast. The years immediately after diagnosis are strikingly critical in terms of their future risk for heart attacks and death. This is shown by a joint study from the Universities of Gothenburg and Oxford.

A new University of Central Florida study indicates that smaller loggerhead and green sea turtles are nesting on Florida beaches than in the past; however, researchers aren't sure why. The findings, published this month in the journal Ecosphere, give clues to the status of the turtles, which is important to researchers who are monitoring the population health of the threatened species.

Rude behavior is a common form of insensitive and disrespectful conduct that harms employees' performance in the workplace. In a new study, researchers examined the impact of rude behavior on how individuals make critical decisions. The study found that in certain situations, these behaviors can have deadly consequences.

A new study suggests that better reporting of adverse effects in drug trials would help inform the public of any potential harms.

Researchers from the University of Sussex have determined the structure of a tiny multi-protein biological machine, furthering our understanding of human cells and helping to enhance research into cancer, neurodegeneration and other illnesses.

If you've ever been to an eye doctor, there's a good chance you've felt the sudden puff of air to the eye that constitutes a traditional test for glaucoma. It's no one's favorite experience, but the puff is non-invasive and harmless. Scientists use a similar method to test learning and memory in animals and humans.

When it comes to what users share on Twitter, women and users who never attended college voluntarily disclose more personal information than users from other socioeconomic and demographic backgrounds -- potentially making these populations more susceptible to online privacy threats, according to a recent study led by the Penn State College of Information Sciences and Technology.

Throughout the pandemic, air sensors watched during lockdowns as air pollution fell in residential and commercial areas, and then as pollution rose again with reopenings. The changing levels, the researchers found, which behaved differently in residential and commercial parts of the city, show where pollution is coming from and how it might change in the future under different policies.
