The convenience, affordability, and flat-out fun of e-bikes and e-scooters are undeniable. But as their popularity grows, the rate of accidents involving e-bikes and e-scooters is climbing. So how do we minimize risks for accidents?

People reckoning with problem drinking choose different paths, including two well-known self-help organizations built around peer support: Alcoholics Anonymous and SMART Recovery. Researchers questioned people participating in these programs, or no program, about their approach.

In 2022, the largest known outbreak spread to nearly 100,000 people in more than 100 countries. Now, a new outbreak of mpox has put it back in the news. What should you know - and do - about this latest international health emergency?

People often aren't aware of the full range of conditions that physical therapy (PT) can effectively treat. PT can be used not only after surgery or injury, but also for stroke, brain injuries, balance problems, neuromuscular conditions, spinal cord injuries, and more. PT is also done to help people avoid falls, as well as for pelvic floor dysfunction and vertigo. People participating in PT work with physical therapists to determine goals and plan a course of treatment to meet those goals by improving mobility, strength, and flexibility.

People with anemia have an abnormally low number of red blood cells. Those are the cells that pick up oxygen from the lungs, deliver oxygen throughout the body, and return to the lungs with a load of carbon dioxide and other gases to be exhaled. Without enough red blood cells, the organs and tissues don't get a sufficient amount of oxygen. That can cause nonspecific symptoms, such as fatigue, headache, or wooziness, which are often attributed to other causes. As a result, anemia often goes undiagnosed.

Artificial intelligence (A.I.) has made an astonishing breakthrough in our understanding of certain biological processes. A.I. has now determined the structure of nearly all proteins in humans, plants, and animals and is exploring the way they interact with each other and with other molecules. This understanding is considered the key to biological medicine, a code that scientists have never been able to crack completely. These advances are expected to speed the development of many potent medicines, vaccines, and cures for some diseases.

The combination of drinking alcohol and sleeping while on a plane puts a big strain on the body, especially the cardiovascular system. This is because blood oxygen normally drops slightly when flying high above sea level, sleeping, or consuming alcohol. The more contributors to low blood oxygen there are, the harder the body has to work to compensate by breathing faster and increasing heart rate. There's even more strain if someone has heart or lung disease, which places the person at a higher risk for a heart attack or stroke.

Online hearing tests help detect if someone has hearing loss. The tests involve answering questions or listening to a series of tones or spoken words. The tests are not as comprehensive as tests conducted by an audiologist, but they are convenient and might help identify mild, moderate, or severe hearing loss; problems hearing particular pitch ranges; or differences in hearing ability in one ear compared to the other (asymmetry). A test might need to be followed up with a visit to an audiologist.
