June 7, 2023 Ponderosa forests struggle in the face of Southwest megadrought 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.
June 5, 2023 Infant universe teemed with full-fledged galaxies crackling with bursts of star formation 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.
June 1, 2023 Grief can increase risk of heart problems, study finds 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.
May 30, 2023 Study provides deeper insight into long COVID 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.
May 25, 2023 A new method for creating 3D images Using computational imaging tools, optical sciences professor David Brady has developed a novel technique called sparse holography that creates three-dimensional images from two-dimensional holograms. The work earned him the Emmett N. Leith Medal from Optica.
May 22, 2023 UArizona researcher at the forefront of Indigenous data sovereignty Stephanie Russo Carroll, associate director of the Native Nations Institute, encourages institutions to adopt policies and practices that recognize Indigenous Peoples' right to control data on their communities, lands and cultures.
May 19, 2023 Would you trust an AI doctor?

However, many put faith in AI if it's monitored and guided by human touch.
May 15, 2023 Scientists use AI to identify likely drug targets in search for Alzheimer's cure 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.
May 8, 2023 UArizona engineers lead $70M project to turn desert shrub into rubber The project, funded by the U.S. Department of Agriculture and Bridgestone, focuses on growing and processing guayule (pronounced why-OO-lee), a hardy, perennial shrub that could be an alternative source of natural rubber.
May 8, 2023 Nearby planetary system seen in breathtaking detail 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.
