Researchers have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and premature aging.

A new study shows that ocean acidification is changing the mix of microbes in coral reef systems, which can be used to assess ecosystem health.

Researchers have created a urine-based test that detects pieces of DNA fragments released by head and neck tumors. The test could potentially facilitate early detection of this cancer type, which currently does not have a reliable screening method.

Researchers who created 'family trees' for nearly 10,000 fish found that first-generation, wild-born descendants of hatchery-origin Chinook salmon in an Oregon river show improved fitness.

Arctic and boreal latitudes are warming faster than any other region on Earth.

In an approach they call 'nanostitching,' engineers used carbon nanotubes to prevent cracking in multilayered composites. The advance could lead to next-generation airplanes and spacecraft.

Scientists have found a way to transform metal waste into a highly efficient catalyst to make hydrogen from water, a discovery that could make hydrogen production more sustainable.

A recent breakthrough study has shown potential to improve therapeutic outcomes for patients suffering from lung cancers.

By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.

A massive new analysis of high seas salmon surveys is enhancing the understanding of salmon ecology, adding details about where various species congregate in the North Pacific Ocean and their different temperature tolerances. The project integrates numerous international salmon studies from the North Pacific dating back to the 1950s.

Researchers have advanced the understanding of how the cerebral cortex develops by tracing the lineage of certain brain cells.

Gender stereotypes mean that girls can be celebrated for their emotional openness and maturity in school, while boys are seen as likely to mask their emotional distress through silence or disruptive behaviors, according to a recent study.

Researchers develop breakthrough technology for wide-ranging and ultra-sensitive active nano-spectral sensor, surpassing current limitations.

Aiming to shorten fracture recovery times, a research group is focusing on plasma irradiation as a treatment method to speed up bone healing.

Young male blue tits are less successful in fathering offspring outside their breeding pair, not because of a lack of experience, but because they are outcompeted by older males, researchers report.

Fires that devastate wildland-urban interface areas are becoming more common around the globe, a trend that is likely to continue for at least the next two decades, new research finds. Such fires are especially dangerous, both because they imperil large numbers of people and because they emit far more toxins than forest and grassland fires.

Tagging marine animals with sensors to track their movements and ocean conditions can provide important environmental and behavioral information. Existing techniques to attach sensors currently largely rely on invasive physical anchors, suction cups, and rigid glues. While these techniques can be effective for tracking marine animals with hard exoskeletons and large animals such as sharks, individuals can incur physiological and metabolic stress during the tagging process, which can affect the quality of data collection. A newly developed soft hydrogel-based bioadhesive interface for marine sensors, referred to as BIMS, holds promise as an effective, rapid, robust, and non-invasive method to tag and track all sorts of marine species, including soft and fragile species. The BIMS tagging, which is also simple and versatile, can help researchers better understand animal behavior while also capturing oceanographic data critical for helping to better understand some impacts of climate change and for resource management.

Simulations on the Stampede2 supercomputer of the Texas Advanced Computing Center (TACC) are helping scientists engineer solutions to overheating of grid transformers -- a critical component of the electric grid.

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.

Scientists using neutrons set the first benchmark (one nanosecond) for a polymer-electrolyte and lithium-salt mixture. Findings could boost power and safety for lithium batteries.
