Workplace gossip is often viewed as negative, but research from The James & Gail Ellis School of Business Leadership has shown that it can play a more complex role in organizational relationships.
A better understanding of how earthquakes occur and what happens during a rupture is important for assessing seismic risk. Small earthquakes, which are more frequent than large ones, are a tempting data set, but they're hard to study, in large part because their energy is
The Draconids and Orionids both peak this month
In early 2024, laboratory-grown neurospheres (i.e. clusters of neural stem cells) were sent to the International Space Station (ISS) to be exposed to microgravity. The return trip was delayed several times due to bad weather in the landing zone. As a result, the cells were
Artificial intelligence is making it easier than ever to create convincing fake political content and harder to tell what's real. Now, a University of Missouri expert is helping voters navigate that changing information landscape ahead of this year's midterm elections.
Evidence for hypernovae, theorized to be the most powerful explosions in the universe, has been disputed in two papers by University College London (UCL) researchers.
Findings recently published in The Quarterly Journal of Economics provide, according to the study's authors, the clearest cause-and-effect evidence to date that noncompete agreements reduce worker mobility and earnings—while offering no measurable benefits in protecting
This summer broke records around the U.K. for maximum temperatures and dry weather. According to the U.K.'s Met Office, while it was rare to hit 35°C (95°F) in the 20th century, that temperature has been surpassed in six out of the past 10 years. And temperatures are only
The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit the solar system multiple times. Using the Gemini North telescope, an international team co-led by
