The Sun emitted a strong solar flare on May 3, 2022, peaking at 9:25 a.m. EDT. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

In the Sierra Nevada, midwinter "rain-on-snow" events occur when rain falls onto existing snowpack, and have resulted in some of the region's biggest and most damaging floods. Rain-on-snow events are projected to increase in size and frequency in the coming years, but little guidance exists for water resource managers on how to mitigate flood risk during times of rapidly changing snowpack. Their minute-by-minute decisions during winter storms can have long-lasting impacts to people, property, and water supplies.

Researchers from the University of Washington and the University of California, Berkeley have conducted experiments that measured the physical limits for the existence of liquid water in icy extraterrestrial worlds. This blend of geoscience and engineering was done to aid in the search for extraterrestrial life and the upcoming robotic exploration of oceans on moons of other planets.

Black employees face a host of subtle verbal, behavioral and environmental slights related to their physical appearance, work ethic, integrity and more, causing job dissatisfaction and burnout, according to a new study from Rice University.

We all must play the game of life with the cards we're dealt, so the common aphorism goes. In biology, this means organisms must compete through natural selection with the genes and anatomy they were born with.

Scientists at NASA's Goddard Space Flight Center in Greenbelt, Maryland, recently received samples of the lunar surface that have been curated in a freezer at NASA's Johnson Space Center in Houston since Apollo 17 astronauts returned them to Earth in December 1972.

Scientists at Scripps Research have unveiled a new software tool for studying RNA (ribonucleic acid) molecules, which have a host of critical roles in organisms. The open-source app, "Pytheas," described May 3, 2022, in Nature Communications, speeds up the process of characterizing and quantifying RNAs in basic research and drug-development settings.

New research from Center for BrainHealth at The University of Texas at Dallas demonstrates that professional development with a focus on neuroscience equips teachers with the tools and confidence to reduce learning gaps in eighth grade students, as measured by State of Texas Assessment of Academic Readiness (STAAR) performance.

The Dung Beetle Ecosystem Engineer (DBEE) project reached a major milestone last month—the arrival of a new dung beetle species, Gymnopleurus sturmi, on Australian shores. It is the third and final dung beetle species imported to Australia as part of the DBEE project.

Word of an extraordinarily inexpensive material, lightweight enough to protect satellites against debris in the cold of outer space, cohesive enough to strengthen the walls of pressurized vessels experiencing average conditions on Earth and yet heat-resistant enough at 1,500 degrees Celsius or 2,732 degrees Fahrenheit to shield instruments against flying debris, raises the question: what single material could do all this?

Companies incorporated in tax havens are often considered more opaque regarding their finances, which could make them risky investments. But a recent study from North Carolina State University finds that many of these companies are actually more transparent than their counterparts in countries that are not tax havens.

Online social networks (OSN) like Facebook and Twitter have created a space for people to easily express their opinions, which can encourage open dialogue and stimulate plenty of disagreements. Research now reveals that just like in face-to-face relationships, intellectually humble behavior, like admitting when you are wrong, leads to better impression formation online.

Are astronauts more likely to develop blood clots during space missions due to zero gravity? That's the question NASA is trying to answer with help from UNC School of Medicine's Stephan Moll, MD, professor in the UNC Department of Medicine. A new publication in Vascular Medicine shows the results of an occupational surveillance program spurred by the development of a deep vein thrombosis (DVT) in the jugular vein of an astronaut, which is described in detail in a New England Journal of Medicine publication from 2020.

A new study published today in Animal Behaviour shows for the first time that brilliant iridescence and gloss found in some animals can have a protective function by working as a form of deceptive warning coloration, and that it is the key feature of iridescence, its changing colors, that is important for this effect.

People who violate their supervised release—a period of community supervision after release from prison—by committing new crimes are punished not only for their crimes, but also for violating their supervision. In a new paper to be published in the Virginia Law Review, Jacob Schuman, assistant professor of law, Penn State, conducted the first comprehensive examination of how revocation of supervised release for new criminal conduct contributes to mass incarceration—a term referring to the high rates of incarceration in the United States.

An online portal developed by the UK Centre for Ecology & Hydrology (UKCEH) will enable forecasters in West Africa to provide communities with earlier and more reliable warnings about large storms.

A new study from the University of Sussex Business School reveals the technologies and academic disciplines that are being overlooked by research funders in the global fight against climate change.

In the coming decade, NASA and China plan to send the first crewed missions to Mars. This will consist of both agencies sending spacecraft in 2033, 2035, 2037, and every 26 months after that to coincide with Mars opposition (i.e., when Earth and Mars are closest in their orbits). The long-term aim of these programs is to establish a base on Mars that will serve as a hub that accommodates future missions, though the Chinese have stated that they intend for their base to be a permanent one.

A wild fox that breached an enclosure at Washington's National Zoo killed 25 flamingos and one duck before escaping, the facility said Tuesday, one month after a rabid fox went on a biting spree near the Capitol.

Researchers at the University of Oklahoma, with the National Renewable Energy Laboratory, the University of North Texas, the NASA Glenn Research Center and several collaborators within the space power community, have recently published a paper in the journal Joule that describes the optimal conditions for testing perovskite solar cells for space.

Sometimes things are fine—until they're not. A boat capsizes. A bridge collapses. The stock market takes an extreme turn.

A study into the management and attitudes of key stakeholders operating in the Great Barrier Reef region has found that past and current approaches do not adequately address climate change threats to the reef or likely losses of species, habitats and processes.

University of the Sunshine Coast researchers and wildlife rescuers have joined forces as they deal with a large increase in stranded, sick, and deceased marine turtles from recent floods and the discovery of a mystery disorder that is eating away at turtle shells.

If there are so many galaxies, stars, and planets, where are all the aliens, and why haven't we heard from them? Those are the simple questions at the heart of the Fermi Paradox. In a new paper, a pair of researchers ask the next obvious question: How long will we have to survive to hear from another alien civilization?

Sometime around 14,000 years ago, the first humans crossed the Bering Strait to North America with canines, domesticated dogs they used for hunting, by their side.
