Using machine learning and simulations of giant impacts, researchers found that planets residing in the inner solar system were likely born from repeated hit-and-run collisions.
Shell beads found in Morocco are at least 142,000 years old. Archaeologists say they're the earliest known evidence of a widespread form of human communication.
UArizona astronomers used massive galaxy clusters as natural magnifying glasses to discover strange galaxies that stopped making stars before their time.
New research suggests winged critters with a penchant for overripe fruit may hold a secret to understanding gene function and autoimmune disorders such as lupus.
Borrowers whose writing is more readable, positive and truthful are less likely to default on a loan and tend to be charged lower interest rates, researchers have found.
Analyzing observations of an X-ray flare and fitting the data with theoretical models, astronomers documented a fatal encounter between an unlucky star and a black hole.
Funded by the NSF Convergence Accelerator Program, the Quantum Sensors project aims to make space and terrestrial navigation far more sensitive, accurate and affordable.
By drilling deep into the Greenland ice sheet, researchers reconstructed the jet stream's past and found that climate-caused disruptions are likely to have drastic weather-related consequences.
New research suggests that the volume of salty water 2 to 10 kilometers (6.2 miles) beneath the Earth's surface is double previous estimates. The water could store waste fluids, sequester carbon and direct our search for extraterrestrial life.
A new UArizona-led study uses big data to assess why the diversity of species varies across the globe. What researchers learned changes our understanding of future diversity in a warming world.
