Some "brutal" weather was bearing down on California on Tuesday, with forecasters warning torrential rain and widespread flooding this week could prove deadly.

Walter Cunningham, the last surviving astronaut from the first successful crewed space mission in NASA's Apollo program, has died. He was 90.

If an underground explosion occurs anywhere in the world, there is a good chance that a seismologist can pinpoint it. However, they won't necessarily be able to tell you what kind of explosion had occurred—whether it is chemical or nuclear in nature. New research from Pacific Northwest National Laboratory (PNNL) scientists makes detecting nuclear explosions easier.

Before any physical conflict, people assess their opponent's features to determine if the ideal tactical response is to fight, flee or attempt to negotiate.

From 2004 to 2014, private high schools opened in more than 200 rural villages in one large Indian state. In a new study, researchers have compared student outcomes in these villages with outcomes in several thousand villages with no private schools.

When the state's wildlife department flung the first handful of lettuce to a starving manatee in the Indian River a year ago, it was an act of desperation driven by a catastrophic die-off and violating an environmental golden rule that animal behavior should not be messed with that way.

Omnipresent fireworks displays won't be the only lights in the sky over the next few nights: There will be natural spectacles, too.

Crouching low among rocky tidepools nearly completely covered with sharp-shelled mussels, California State Parks interpretive manager Robyn Chase gave out a sharp cry.

As the New Year begins, California's Sierra is closing in on the second-largest snowpack we've seen at this time of year in the last two decades, with more snow expected to pummel the mountain range in the coming days.

A new study has found that a plume of per- and polyfluoroalkyl substances (PFAS) from an industrial source has made its way into Green Bay, Lake Michigan, through the movement of groundwater.

A new North Carolina State University study shows the potential for using Twitter and online news articles to track the timing and location of invasive insect spread in the United States and around the globe. Researchers say these sources are promising for filling in gaps when official data are not widely available.

Lasers find applications across several fields ranging from telecommunications and remote sensing to medicine. There are many ways in which one can generate laser emission, or lasing, from a device or material. Consequently, there are many types of lasers with different principles of operation.

The ability to transmit and manipulate, with minimal loss, the smallest unit of light—the photon—plays a pivotal role in optical communications as well as designs for quantum computers that would use light rather than electric charges to store and carry information.

A new study investigates a novel process for lessening the negative environmental impact of coal mine drainage and extracting rare-earth elements from it, precious minerals needed to manufacture many high-tech devices.

Coprolites (fossil feces) from around 30,000 years ago have been used to identify the presence of bearded vultures (Gypaetus barbatus) at the Paleolithic site of Lagar Velho (Portugal). A comparison of the coprolites found in the excavations with the feces of present-day lammergeyers has confirmed the presence of these animals in the past. The research study, published in the journal Scientific...

Researchers at North Carolina State University have developed a stretchable strain sensor that has an unprecedented combination of sensitivity and range, allowing it to detect even minor changes in strain with greater range of motion than previous technologies. The researchers demonstrated the sensor's utility by creating new health monitoring and human-machine interface devices.

Antibiotics are being used less and less in fattening animals. This is the result found by the report, "Treatment Frequency and Antibiotic Consumption Quantities 2018–2021: Trends in Cattle, Pigs, Chickens and Turkeys Kept for Meat Production," by the German Federal Institute for Risk Assessment (BfR). The BfR is tasked with evaluating the data on antibiotic use provided by the German federal...

In dual-earner couples, working from home may be a better deal for husbands than wives in some ways, according to two related studies of workers in China and South Korea.

A large volcanic outburst was discovered on Jupiter's moon Io by Jeff Morgenthaler of the Planetary Science Institute using PSI's Io Input/Output observatory (IoIO).

ABC transporters constitute a major class of multidrug resistance proteins, e.g., in cancer cells. Membrane lipids have been long known to influence the structure and functional dynamics of these proteins. However, previous structural and biochemical studies on ABCG2 are limited either by their static description or low spatial resolution to provide a microscopic view of the dynamics of the drug...

A study carried out at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) heralds a paradigm change in the field of mechanobiology. The study reveals that cells respond to forces of differing strength using use two distinct mechanisms, one mediated by minute, cup-like invaginations on the cell surface called caveolae and the other by newly discovered large membrane depressions the...

Salmonella are food-borne pathogens that infect millions of people each year. To do so, these bacteria depend on a complex network of genes and gene products that allow them to sense environmental conditions. In a new paper, researchers have investigated the role of small RNAs that help Salmonella express their virulence genes.

Researchers at Queen Mary University of London have shown that zebrafish can provide genetic clues to the evolution of social behaviors in humans and domesticated species.

Scientists have discovered a way to train healthy immune cells to acquire the skills of some tumor cells—but for a good purpose—to accelerate diabetic wound healing. This remarkably promising finding, recently published in EMBO Molecular Medicine, may open up a brand new avenue for regenerative medicine.
