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

If you've ever felt overwhelmed by menu options at a restaurant, cereal varieties at the grocery store or potential partners while scrolling through dating apps, you've experienced choice overload.

Dark matter could be a type of matter in the universe that does not emit, absorb or reflect detectable light and appears to interact very weakly with regular matter. Although physicists have observed gravitational effects attributed to dark matter, they have not yet been able to

When you swim through the azure waters of the Great Barrier Reef, there is one creature on the seafloor that's almost impossible to miss: the giant clam. Its huge, fluted shell frames a soft mantle shimmering with electric blue, green and gold.

As Ted Schuur stepped along the edges of Smith Lake, a bubble surfaced from the muck underfoot. And then another. They're bubbles of methane, a potent heat-trapping gas made from decomposing plants and animals that had once been stuck in Alaska's frigid permafrost. But that froze

Deep in Peru's Acarí Valley lie the ruins of Tambo Viejo, an Inka provincial center where excavations have uncovered tasseled sacrificial llamas and brightly adorned guinea pigs. But save for a few seeds and some stored leaves, evidence of how the Inka used one of their most sacr

Tiny magnetic fields created shortly after the Big Bang may help explain the long-running disagreement over how fast the universe is expanding. Detailed simulations show that these primordial fields could have changed the formation of hydrogen in the early universe, affecting the

When light travels through a strongly scattering material, such as biological tissue or other disordered opaque media, it follows many different paths and produces a seemingly random speckle pattern. Wavefront shaping makes it possible to control this complex interference and foc

A UCLA study links faster brain aging to specific gut bacteria and chemical byproducts, with older-looking brains also associated with poorer memory, focus, and mood. The findings suggest that biological signs of brain aging may appear decades before obvious symptoms and could ev

The picturesque Lac des Brenets between France and Switzerland has dried up after a record-breaking hot summer, leaving locals crying out for help to save the lake.

How can the same El Niño cause drought in one part of the world and floods in another? and more — today's news signal.

A vitamin D analog may help break down pancreatic cancer’s protective defenses, potentially making tumors more vulnerable to chemotherapy and immune attack. A small clinical trial found encouraging responses, especially in patients whose tumors had high levels of the vitamin D re

The Pacific Ocean is warming unusually quickly, and this year's El Niño has already surpassed previous records. Forecasters expect it to strengthen even further before approaching its usual peak around December.

Recently, spatial omics has become a powerful tool, enabling researchers to see not only what molecules are present in a tissue, but also where they are located and how they are organized across cells, tissue structures and local microenvironments. This spatial context has deepen

A systematic review of informal businesses published in the International Journal of Entrepreneurship and Small Business argues that they should be treated as part of the larger entrepreneurial ecosystem rather than as a peripheral feature of the economy.

Students in a new study were neither clearly positive nor negative about more climate-friendly school meals. Whether the food tasted good, was filling and felt familiar played an important role. Students were somewhat more positive about reducing the amount of meat in recipes tha

An international team of astronomers, including researchers from the Department of Physics and the Hong Kong Institute for Astronomy and Astrophysics (HKIAA) at The University of Hong Kong (HKU), has discovered a previously hidden phase of high-energy activity following the merge

Saturn's icy moon Enceladus hides a global ocean beneath its frozen surface. From fractures near its south pole, material from this ocean is ejected into space as a plume of water vapor and ice particles. These particles offer scientists a rare opportunity to investigate an extra

The U.S. prison population is declining at an accelerating rate, and prison admission rates are predicted to fall an additional 50% within the next two decades, according to new research from University at Albany professor Shawn Bushway.

A meteor crater buried beneath Oklahoma has turned out to be nearly 100 million years younger than scientists thought. Zircon crystals show the Ames impact occurred about 370 million years ago, meaning it was not part of the mysterious Ordovician bombardment once linked to a poss
