Ketamine use among electronic dance music party-goers is much higher than previously thought. And unintentional use appears to play a role, a new study finds.
Ketamine is known as Special K on the party scene. The operating room anesthetic was approved by the U.S. Food and Drug Administration in 2019 as a treatment for depression. But it has long been used as a club drug.
Having fewer liquor stores in cities may lead to lower murder rates, a new study suggests.
The implication of alcohol zoning regulations can have life-or-death consequences -- at least in Baltimore, according to study author Pamela Trangenstein, of the University of North Carolina at Chapel Hill, and colleagues.
"There is an ongoing violence epidemic in Baltimore, with recen...
Whether you're stopping at a casual fast-food place or sitting down to eat in a full-service restaurant, eating out is an easy way to fill up when you're hungry. But those meals may not deliver much nutritional value, a new study suggests.
The researchers found that 70% of fast-food meals consumed in the United States were of poor nutritional value. For full-service restaurants, ...
Young school-aged children with behavior problems may have different bacteria in their guts than their well-behaved peers, new research suggests.
The study also noted that parents may play a key role in development of the particular bacteria in their child's gut (collectively known as the microbiome). That role even extends beyond the type of foods parents give their children, resear...
There's more evidence that the canine-human bond is a tight one: New research finds that stray dogs pick up on human commands, even though they haven't been trained.
Of the untrained dogs in the study, 80% went to the place a person pointed to. This suggests dogs understand complex gestures by watching humans, which might be a clue to reducing conflict between stray dogs and peop...
U.S. cancer survivors have surprisingly high rates of alcohol use, researchers say.
"This study highlights the prevalence of current alcohol use among cancer survivors, including an increase in alcohol intake over time and higher rates among younger cancer survivors," said Dr. Crystal Denlinger, chief of GI Medical Oncology at Fox Chase Cancer Center in Philadelphia.
People who love their green tea may also enjoy longer, healthier lives, a large new study suggests.
Researchers found that of more than 100,000 Chinese adults they tracked, those who drank green tea at least three times a week were less likely to suffer a heart attack or stroke over the next seven years.
Tea lovers also had a slightly longer life expectancy. At age 50, they ...
Teenagers who've experimented with opioid painkillers are likely to be taking other health risks, a new study finds.
In a national survey of U.S. high school students, 14% said they had ever "misused" a prescription opioid such as Vicodin, OxyContin or Percocet. And those teenagers were much more likely than their peers to admit to taking a range of risks -- from abusing other dru...
You made your resolution -- this year was finally going to be the year you lost weight. But then your neighbor stopped by with a plate of cookies, and well, your resolve didn't even last a day. Maybe next year?
But instead of looking at your resolutions as a sweeping year-long project, what if you concentrated on making healthy changes every Monday? That way, if you slip up and dive ...
As electronic-cigarette use has soared among America's teens, so too has the number vaping marijuana, two new reports indicate.
A team from the University of Nebraska found youth use of pot in e-cigarettes rose from 11% in 2017 to 15% one year later. And University of Michigan researchers found that in 2019, 14% of 12th graders reported marijuana vaping in the prior month...
Children diagnosed with attention deficit hyperactivity disorder (ADHD) tend to lag behind their peers long after they leave school, earning less as adults and living with their parents longer, a new study finds.
This is often true even if the hallmark symptoms of the disorder -- including inability to focus, hyperactivity, fidgetiness and impulsivity -- appear to have abated.
Only a few people seem able to decipher what most people consider unreadable expressions on cats' faces, researchers find.
These "cat whisperers" can discern subtle differences on feline faces that reveal their mood. Women and people in the veterinary field, but not necessarily cat lovers, are most likely to have this ability.
"The ability to read animals' facial expressions...
Skyrocketing prices and insurance limits are driving many people with diabetes to seek medications and supplies from an underground supply chain, a new study found.
"The cost of insulin, which is required in type 1 diabetes and a subset of type 2 diabetes, has increased substantially over the last decade. As the price of insulin rises and insurance premiums and deductibles go up, too...
More Americans are having trouble falling and staying asleep, and smartphones and technology are probably to blame, researchers report.
Their analysis of data from nearly 165,000 adults nationwide showed that the number who reported difficulty falling asleep at least once a week was up 1.4% between 2013 and 2017, and those who had trouble staying asleep rose 2.7%.
Making the decision to live healthier often involves important steps such as losing weight and exercising more. These are significant goals and everyday lifestyle habits that you should commit to. But there's another type of "makeover" that can benefit you in equally important ways.
That's changing your general outlook on life by boosting positivity. This mental tweak will put you in ...
After the University of California, San Francisco, banned sales of sugary drinks, employees started downing less liquid sugar -- and their waistlines showed it.
In a before-and-after study, researchers found that the ban, begun in 2015, cut employees' intake of sugary drinks by almost 50%. And within 10 months, their collective waist size had shrunk by almost an inch.
Children with an autism spectrum disorder may be twice as likely to experience pain as kids without autism, a new study suggests.
"Pain is a common but under-recognized experience for children with autism," said researcher Danielle Shapiro. She is an assistant professor of clinical psychology at the University of Michigan, in Ann Arbor.
Research has long shown how psychological disorders lead to poor physical health. Now scientists are learning more about the flip side of emotions, how living a purposeful life may have as many physical benefits as inspirational ones.
Having purpose in life is simply believing that your life has meaning and that you live according to goals you set for yourself.
Dealing with the agitation, anxiety and aggression that often come with dementia is one of the most challenging aspects of caring for someone with this brain disorder. But new research suggests that massage and other non-drug treatments may be more effective than medications.
Even just taking people with dementia outdoors can help, said study author Dr. Jennifer Watt, a geriatrician ...
Historically, black teenagers in the United States have had lower suicide rates than whites. But a new study finds that more black teens have been attempting suicide in recent years -- and experts are not sure why.
Researchers at New York University found that between 1991 and 2017, there was an increase in the number of black teenagers who said they'd att...
How do you make healthy food more popular? Start by giving it a yummy-sounding name, researchers say.
People are much more likely to choose good-for-you foods like broccoli or carrots if labeled with names that emphasize taste over nutritional value, according to Alia Crum, an assistant professor of psychology at Stanford University, and her colleagues.
College kids who get good shuteye may stand a better chance of making the Dean's list, a new study finds.
"The fact that there was a correlation between sleep and performance wasn't surprising, but the extent of it was," said researcher Jeffrey Grossman. He's a professor in the department of materials science and engineering at Massachusetts Institute of Technology (MIT).
Attention-deficit/hyperactivity disorder (ADHD) is in the news a lot, and now newer research has prompted a leading pediatricians' group to update its guidelines for diagnosing and treating the disorder for the first time since 2011.
Dr. Mark Wolraich, lead author of the guidelines, noted that there weren't any dramatic differences between these and previous guidelines. But, he said,...
