Science, engineering, and discovery — the research and breakthroughs that matter.

The cuts of meat in a supermarket case can look perfectly fresh even as bacteria are already multiplying inside the package. Is there a way to know before you open it?

Understanding the formation and evolution of the centers of galaxies is one of the most intriguing challenges in astrophysics. The new study aims to unveil the physical processes that led to the formation of two striking features surrounding the black holes at the centers of most

When UC Berkeley postdoctoral researchers Maya Zomer and Lucia Layritz first drove through burned portions of Mojave National Preserve in Southern California, the sight stunned them. "It looks like a pretty dystopian landscape," Layritz said.

The recent confirmation of an atmosphere around a rocky exoplanet called LHS 1140b has created a wave of interest within the astronomy community. The planet orbits within the habitable zone around its parent star—a red dwarf located some 48 light-years from Earth.

As consumers, we are constantly making choices about things like what to eat at a restaurant, what clothing to buy at a store and the type of car we'd like to purchase, and so much more. Savvy producers of such goods look to economists to help estimate what products people want a

The explosion of new data centers being proposed and built around the U.S. has increased demand for energy to keep them powered and cooled. The Electric Power Research Institute estimates that data centers could consume up to 9% of U.S. electricity generation annually by 2030, up

Researchers from Kiel University and Trier University have shown, for the first time, that a widely used deworming product for grazing animals doesn't just harm individual plants and insects but also alters entire networks of ecological relationships. The active ingredient invest

One of the hallmarks of Alzheimer's disease is the accumulation of a peptide in the brain known as amyloid beta. A new study published in Nature Communications on July 22 has uncovered the atomic structure of the peptide in its harmful form.

A model developed by Washington State University researchers could someday help communities determine how best to motivate homeowners to prepare their properties for possible wildfires.

A new study led by Southwest Research Institute (SwRI) provides evidence that liquid nitrogen is rising to Pluto's surface through cracks at the northern edge of Sputnik Planitia, part of the massive heart-shaped glacier on the dwarf planet's surface. This is the first evidence o

Pacific islands alarmed by Trump-backed push for deep-sea mining and more — today's student signal.

A Pacific island leader says there were "no consultations" before the U.S. announced swaths of nearby ocean could be auctioned for deep-sea mining exploration, telling AFP the industry faced strong opposition among his people.

Many parents have mixed feelings about the unrestricted use of artificial intelligence (AI) for schoolwork. They are concerned about the potential impact on their child's ability to learn but also don't want them to be left behind if other young people are using AI.

If you ask Vijay Parashar, associate professor of medical and molecular sciences (MMSC) at the University of Delaware College of Health Sciences, human bodies are bags of bacteria. "It sounds gross, but not all bacteria are bad; most of them are good. The trouble starts when the

Supercontinuum light sources—often called "white lasers" because they emit a broad, continuous rainbow of colors—are essential tools for everything from advanced medical imaging to environmental gas detection. However, researchers have historically faced a frustrating trade-off:

People in communities thousands of miles apart have described the same strange experience after eating a mysterious mushroom: vivid visions of tiny humans moving through and interacting with the physical world around them. Known as Lilliputian hallucinations—a reference to the 6-

The cuts of meat in a supermarket case can look perfectly fresh even as bacteria are already multiplying inside the package. Is there a way to know before you open it?

The Sloan Digital Sky Survey V (SDSS-V) has announced its 20th public data release (DR20), delivering a dramatic expansion of the Milky Way Mapper (MWM) scientific survey—the most detailed spectroscopic map yet assembled of stars in and around our home galaxy.

Scientists have long known that ant colonies sometimes seem to move as one. A nest that appears quiet can suddenly erupt into activity, with workers throughout the colony springing into motion almost simultaneously before settling back into stillness.

A new study by ancient DNA researchers at the University of California, Santa Cruz, used paleogenomics to create a genetic roadmap to help guide the restoration of another iconic species once on the brink of extinction: the North American bison.

Researchers have demonstrated a solid-state organic laser microcavity fabricated entirely by solution processing. The device operates in the strong light–matter coupling regime, where light and matter form hybrid states called polaritons. This makes the platform not only a new ty

For the first time, scientists have observed a three-dimensional woven structure forming naturally inside a crystal, revealing a previously unknown way in which matter can organize itself.

Agriculture covers more than 40% of Earth's habitable land and plays a central role in both climate change and biodiversity loss. Yet the impact of agriculture is far from evenly distributed across space.

When Pepper the social robot was given the chance to try its hand as a teaching assistant, it showed that it can be even better than a human teacher at motivating pupils and helping them learn.
