The ponderosa pine is one of the most ubiquitous conifer species in western North America. In the American Southwest, winter snowmelt and summer rains play a critical role in ponderosa forests' survival, but the 23-year megadrought may have these semi-arid trees at the end of their rope, according to new research by UArizona scientists.
NASA's James Webb Space Telescope has uncovered an unexpected bounty of full-fledged galaxies at a time when the universe was just getting started. Researchers learned that these galaxies went through bursts of star formation.
UArizona researchers studied the impact of grief on heart function and found that severe grief can cause a marked rise in blood pressure. The findings suggest that grief could be a risk factor for cardiac events.
Symptoms of long COVID include fatigue, brain fog and dizziness that last for months or years after a person is initially infected. A study of nearly 10,000 Americans found that long COVID may be more common and severe in those infected before the 2021 omicron variant.
Flandrau Science Center & Planetarium's newest exhibit, "Undersea Discovery," takes visitors on a journey from the ocean shore to its rarely seen depths, providing a look at the colorful animals and plants that make up the vast waters of the world.
The grant, from the U.S. Department of Education's Developing Hispanic-Serving Institutions Program, will fund activities focused on the U.S.-Mexico borderlands, including a student internship program, first-year writing curriculum and faculty fellowships.
Artificial intelligence-powered medical treatment options are on the rise, but more than 50% of people don't fully trust them, a new study finds. However, many put faith in AI if it's monitored and guided by human touch.
Scientists at the UArizona Lunar and Planetary Laboratory have created an online portal that allows members of the public to help discover asteroids hurtling through our solar system.
Researchers harnessed the power of artificial intelligence to identify causes of Alzheimer's disease and potential drug targets. They looked deep into the brain to map the changes healthy neurons undergo as the disease progresses.
A new Webb Space Telescope image of the bright, nearby star Fomalhaut reveals its planetary system with details never seen before, including nested concentric rings of dust. These belts most likely are carved by the gravitational forces produced by embedded, unseen planets.
