One of the top worries about telehealth is that it will drive up the use of tests and scans that patients don't need, wasting money and resources. In fact, a new study shows, low-value care didn't rise faster at primary care practices that used telehealth the most. Read more ›

Higher temperatures caused by anthropogenic climate change turned an ordinary drought into an exceptional one that parched the American West from 2020--22. A study has found that evaporation accounted for 61% of the drought's severity, while reduced precipitation accounted for 39%. The research found that since 2000, evaporative demand has played a bigger role than reduced precipitation in droughts, which may become more severe as the climate warms. Read more ›

Research sheds light on how coyotes, North America's most successful predators, are responding to various environmental pressures, including human development, hunting and competition with larger carnivores. Surprisingly, the study's findings suggest that human hunting practices may actually contribute to increasing the number of coyotes. Read more ›

When Mount St. Helens erupted in 1980, lava incinerated anything living for miles around. As an experiment, scientists dropped gophers onto parts of the scorched mountain for only 24 hours. The benefits from that single day were undeniable and still visible 40 years later. Read more ›

New collaborative research has shown that using a fan in hot and humid weather reduces cardiac strain in older people, contradicting recommendations from the Centers of Disease Control and Prevention in the US. The study looked at the efficacy of different low-cost cooling strategies -- such as electric fans with and without spraying water on the skin -- for older adults, who are known to be at a heightened health...

Scientists have identified 16 genes that breast cancer cells use to survive in the bloodstream after they've escaped the low-oxygen regions of a tumor. Each is a potential therapeutic target to stop cancer recurrence, and one -- MUC1 -- is already in clinical trials. Read more ›

Exhaled breath contains chemical clues to what's going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses -- and improve patients' prospects. Researchers report developing ultrasensitive, nanoscale sensors that in small-scale tests distinguished a key change in the chemistry of the breath of people with lung cancer. Read more ›

Gamma radiation can convert methane into a wide variety of products at room temperature, including hydrocarbons, oxygen-containing molecules, and amino acids, reports a research team. This type of reaction probably plays an important role in the formation of complex organic molecules in the universe -- and possibly in the origin of life. They also open up new strategies for the industrial conversion of methane into high value-added products under mild... Read more ›

The cost of childbirth and postpartum health care results in significant, ongoing financial hardship, particularly for lower-income families with commercial insurance. About half of people who give birth in the United States are covered by commercial health insurance, which typically requires cost-sharing in the form of deductibles, copayments, and coinsurance.

A team of bioengineers has developed a mathematical model that clarifies why interleukin-12 (IL-12) -- a potent immune-boosting protein that holds promise for cancer treatment -- loses effectiveness over time when used as an immunotherapeutic. The research challenges long-held assumptions about IL-12 s behavior in the body and offers a path toward safer and more effective dosing regimens. Read more ›
