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.

A 2024 analysis found that many people without heart problems are taking daily low-dose aspirin therapy, even though it might have more health risks than benefits. Some of them have not consulted with a doctor about whether daily aspirin is safe for them.

In 2024, RSV vaccinations are recommended for infants and young children; everyone ages 75 and older, regardless of health; and people ages 60 to 74 at increased risk for severe RSV, such as people with lung or heart disease or those who live in nursing homes.

A 2024 study of more than 215,000 people (ages 37 to 73) found a link between consuming a sodium-rich diet and increased risks of having eczema, an eczema flare-up, or severe eczema.

Compared with people who eat out frequently, people who eat meals made at home tend to weigh less, have healthier cholesterol and blood sugar values, and are less likely to develop diabetes. Lack of time, not lack of skills, may be the biggest barrier. Tips for creating healthy, home-cooked meals include smart ways to stock a pantry, fridge, and freezer with legumes and whole grains. For example, people can use an electric pressure cooker to make a dozen or more half-cup servings of brown rice that can then be stored in the freezer. This technique, called batch cooking, can be used with dried beans as well as with flavor enhancers such as minced garlic and ginger.

Small animals like turtles, iguanas, and frogs are often chosen as first-time pets for children, but it may be best to avoid them because they can carry bacteria that can make people sick. Here's what to know about this illness.
