Einstein's general theory of relativity – the idea that gravity is matter warping spacetime – has withstood over 100 years of scrutiny and testing, including the newest test by University of Arizona astrophysicists from the Event Horizon Telescope collaboration.

When doing laundry at home, the Centers for Disease Control website said people can "launder items as appropriate in accordance with the manufacturer's instructions." But it recommends using the warmest water the fabric will allow and drying the items completely.

The OSIRIS-REx mission is gearing up for its first attempt to collect a sample from asteroid Bennu this month. But before even touching the surface, scientists are learning more than ever about the material that makes up the asteroid.

Jennifer Carlson, an author and an associate professor in the University of Arizona School of Sociology, writes about the variety of factors that have led to an increase in gun sales since March.

A recent standoff is the culmination of longstanding tensions over water between the United States and Mexico that have recently exploded into violence, pitting Mexican farmers against their own president and the global superpower next door. "These tensions, these tendencies, are already there, and they're just made so much worse by climate change," said Christopher Scott, a professor of water resources policy at the University of Arizona. "They are in a fight for their lives, because no water, no agriculture; no agriculture, no rural communities."

University of Arizona Heath Sciences researchers developed one of the most accurate COVID-19 antibody tests available and now have shown antibodies persist for months after infection, providing long-term immunity.

Many election experts have warned it might take days or even weeks after Election Day for a final outcome in the presidential race due to the unprecedented deluge of mail ballots amid the coronavirus pandemic. But the country could get major clues on election night even as counting continues in some key states. "I think the conventional wisdom of this thing taking weeks or many, many days is probably wrong," said Thomas Volgy, a political science professor at the University of Arizona.

U.S. coronavirus cases are rising again, driven by rapid transmission in Midwestern states and sparking fears that a forewarned wave of infections this fall and winter has begun. "My biggest concern is around the continued vigilance that prevention requires – the distancing, masking, avoidance of crowded indoor areas, etc. The fatigue factor sets in," said Saskia Popescu, an epidemiologist at the University of Arizona.
