While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star's gas disk at impossibly high speeds. What's more, they believe the jet is caused by strong magnetic forces surrounding the star.

While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA)—an international observatory co-operated by the U.S. National Science Foundation's National Radio Astronomy Observatory (NRAO)—scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy.

Scientists say they have begun to decipher the symbols on Ice Age cave art  — and it all started with a hunch by an enthusiastic amateur...

Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way's stellar halo. The most distant of these stars is more than a million light years from Earth, almost half the distance to our neighboring galaxy, Andromeda, which is about 2.5 million light years away.

Edie Widder is one of the few people in the world who has been to the bottom of the ocean. She's a deep-sea ocean explorer, and among many discoveries, was the first person to ever capture a giant squid on camera.

If you lift your eyes to the sky Friday night, you can catch the first full moon of 2023—the wolf moon.

Heavy rain lashed water-logged California Monday, with forecasters warning of floods as a parade of storms that have killed 12 people battered the western United States.

Police investigating the murders of four University of Idaho students have said they used DNA to link evidence found at the crime scene to their suspect, 28-year-old Bryan Kohberger.

In today's digital age, computational tasks have become increasingly complex. This, in turn, has led to an exponential growth in the power consumed by digital computers. Thus, it is necessary to develop hardware resources that can perform large-scale computing in a fast and energy-efficient way.

The Los Angeles River roared to life this week as a series of powerful storms moved through the Southland. In Long Beach, 3 feet of water shut down the 710 Freeway in both directions, while flooding in the San Fernando Valley forced the closure of the Sepulveda Basin.

A 30-foot juvenile humpback whale washed up on the beach in Atlantic City on Saturday morning, the second time in 15 days a young whale has been swept ashore in the casino town.

A case study involving Europe's largest coal-fired power plant shows space-based observations can be used to track carbon dioxide emissions—and reductions—at the source.

Artificial food dyes have been linked to multiple health concerns, including hyperactivity in children, allergies, and certain cancers. The science isn't settled and the Food and Drug Administration says color additives are safe, but consumers are nonetheless clamoring for natural alternatives.

Mosquitoes spread several diseases, among them malaria and dengue virus. In 2020, about 241 million cases of malaria occurred worldwide, with a few more million cases occurring in 2021. Nearly half the world's population lives in regions where contracting dengue virus is a risk. Insects also destroy a third of agriculture.

As seasoned gardeners know, broccoli heads don't develop properly and can resemble cauliflower when grown in higher temperatures.

The new year brings challenges to Biden administration regulators: how to handle environmentally unfriendly riders inserted by lawmakers into the fiscal 2023 spending bill.

Two newly published articles by researchers at the University at Albany and Northwestern University show the extent to which civilians working to intervene in and de-escalate street violence face job-related violence themselves, as well as secondary trauma from that violence.

The 80th Golden Globe Awards this week kicks off Hollywood's annual awards season, which culminates with the Academy Awards in March.

The Orion space capsule from Artemis I has come full circle, having launched from Kennedy Space Center, traveled 1.4 million miles in space and around the moon, splashed back down to Earth in the Pacific Ocean, and now journeyed 2,500 miles over land for its return to Florida.

The U.S. Coast Guard was working with state officials Saturday to determine the cause of a large oil slick in the waters off Santa Barbara County.

New research by scientists at the University of California, Riverside, has potential in insect control through volatile repellents that could be applied on surfaces such as windowsills, eves of huts, house entryways, backyards, outside produce storage areas, entryways of livestock shelters, and next to crops in a field.

Climate change will reshape ecosystems through two types of events: short-term, extreme events -- or 'pulses' -- and long-term changes, or 'presses.' Understanding the effects of presses and pulses is essential as conservationists and policymakers try to preserve ecosystems and safeguard biodiversity. Researchers have discovered how different presses and pulses impacted Magellanic penguins -- a...

Save the ... parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn -- and that means not just fewer worms, but losses for the entire ecosystem.
