FRIDAY, March 11, 2022 -- Sick people seeking lifesaving care in the United States could fall victim to a hidden part of Russia's war on Ukraine -- vicious cyberattacks aimed at sowing disruption, confusion and chaos as ground forces advance.

Cybersecurity experts warn that attacks launched against Ukrainian institutions have the potential to spill over into America's health care systems,...

It's crucial to keep preschoolers away from screens and other sources of light in the hour before bedtime if you want them to get a good night's sleep, researchers say.

That's because even a little bit of light exposure can trigger a sharp drop in the sleep-promoting hormone melatonin, according...

A robot performed challenging keyhole surgery on pigs without any human help in what could be a major step toward fully automated surgery on people.

"Our findings show that we can automate one of the most intricate and delicate tasks in surgery: the reconnection of two ends of an intestine," said senior study author Axel Krieger. He is an assistant professor of mechanical engineering at J...

The pandemic has made Zoom meetings a daily reality for millions. For many, having to watch their own face in a meeting is the worst part.

But that's not true for everyone, new research shows.

"Most people believe that seeing yourself during virtual meetings contributes to making the overall experience worse, but that's not what showed up in my data," said study author Kristine Kuh...

Chatting with your doctor via video about your health issues works just as well as an in-person office visit, at least when it comes to managing chronic illnesses, a new review suggests.

Replacing office visits with video checkups delivered results that were just as effective for patients being treated for conditions like diabetes, respiratory illnesses, chronic pain, heart problems and n...

Children and teens who use livestreaming gaming platforms may be bombarded with influencer-endorsed ads for energy drinks, junk food and alcohol, new research shows.

"This type of marketing can normalize high-fat, high-sugar and high-sodium foods at a time in young viewers' live...

The misconception that girls are less interested than boys in computer science and engineering begins at a young age in the United States.

And it's one reason for the gender gap in those career fields, according to a new study.

In surveys of more than 2,200 U.S. children and teens in grades 1 through 12, researchers found that half -- 51% -- believed girls are less...

Call it the great pandemic sit-down.

As COVID-19 turned daily commutes into shuffles between rooms at home, and Netflix replaced time spent at the gym or playing sports, Americans have been sitting a lot more. Now a new study suggests it may be putting their mental health at risk.

"We knew COVID was going to affect our behavior and what we could do in lots of weird, funky ways that ...

Modern Americans get much less physical activity than their forebearers did 200 years ago, and increasing reliance on technology is a major reason why.

That's the finding from researchers who used data on falling body temperature and changing metabolic rates in the United States to measure de...

Even in normal times, getting regular exercise and spending less time on screens can be good for kids. So it should come as no surprise that researchers discovered that kids who exercised more and used technology less during the pandemic had better mental health outcomes.

"Both as a pediatrician and as a mother, it was obvious that the circumstances of the pandemic -- school closures, res...

In a health emergency, social media giants like Facebook can be both quagmires of misinformation and sources of social support and reliable guidance, a small, new study suggests.

Researchers surveyed 32 Facebook users weekly for eight weeks. All were asked about their online experiences during March and April 2020, when COVID-triggered lockdowns unfolded.

The Facebook users -- ...

Whether you're a kid or a college student, you'll learn more with interactive activities, discussions, movement and even AI-enhanced technologies than you will just sitting still and listening, a new study suggests.

Learning methods that work best are hands-on, as well as what the researchers called "minds-on" and "hearts-on," using emotional and social support, the findings showed.

Artificial intelligence (AI) might be able to spot the next virus to jump from animals to humans, Scottish researchers report.

Identifying diseases before they become a threat to humans is challenging, because only a few of the nearly 2 million animal viruses can infect humans. By developing machine learning models, researchers can analyze genetic patterns of viruses that might infect peo...

An artificial intelligence tool could help radiologists spot breast cancer on ultrasound images and reduce the need for extra testing, new research suggests.

"Our study demonstrates how artificial intelligence can help radiologists reading breast ultrasound exams to reveal only those that show real signs of breast cancer, and to avoid verification by biopsy in cases that turn out to be be...

Radiologists still outperform artificial intelligence (AI) when it comes to breast cancer screening, a new paper shows.

Many countries have mammography screening programs to detect and treat breast cancer early. However, examining mammograms for early signs of cancer means a lot of repetitive work for radiologists, which can result in some cancers being missed, the authors explained.

Take a work break: A small, new study suggests that getting out of your chair every half hour may help improve your blood sugar levels and your overall health.

Every hour spent sitting or lying down increases the risk for metabolic syndrome and type 2 diabetes, the study authors said. But moving around during those sedentary hours is an easy way to improve insulin sensitivity and reduce t...

Want to see a temperamental tween or teen act happier?

The formula is simple, a large international study suggests.

"Screen time should be replaced by 'green time' for optimizing the well-being of our kids," said study author Asad Khan, an associate professor in biostatistics and epidemiology at the University of Queensland in Brisbane, Australia.

That advice stems from survey...
