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.
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.
UArizona is ranked No. 95 overall, No. 48 among U.S. institutions and No. 25 among public colleges and universities in the annual Center for World University Rankings.
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.
Using the James Webb Space Telescope, astronomers observed detailed features, including roiling clouds of dust, in the atmosphere of a brown dwarf planet 40 light-years away.
Imagine a home computer operating 1 million times faster than the most expensive hardware on the market. Now, imagine that being the industry standard. UArizona physicists hope to pave the way for that reality.
Mapping a large coastal glacier in Alaska revealed that its bulk sits below sea level and is undercut by channels, making it vulnerable to accelerated melting in an already deteriorating coastal habitat.
Future space missions likely will send robots to scout out underground habitats for astronauts. UArizona engineers have developed a system that would allow autonomous vehicles to explore caves, lava tubes and even oceans on other worlds.
More environmentally friendly agriculture practices are needed to keep the farming industry strong in Arizona, a report from the university's Southwest Center finds.
