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

Most people underestimate how much light a pair of sunglasses blocks out. A typical dark pair removes around 80% to 90% of the visible light reaching the eye.

The North Dakota Agricultural Weather Network—known as NDAWN—isn't just measuring precipitation amounts and temperatures across the state. It's also playing a role in developing tools for crop disease management.

The Amish, a Christian denomination and a three-century-old ethnic group of German migrants known for its strict lifestyle standards, are one of the fastest-growing minority populations in the U.S. For more than a century, the number of Amish people—whose American lineage traces

The adult brain may be far better at repairing itself than scientists once believed. In mice, researchers discovered a special group of support cells called astrocytes that respond to damaged brain tissue by rebuilding lost cellular networks. Rather than simply moving into the in

The Western U.S. is experiencing periods of increasingly intense drought, and higher temperatures are exacerbating the issue by drawing even more moisture from plants and soils into the atmosphere. The results can be seen in the ever-expanding wildfire footprint, with many of the

Total solar eclipse to spellbind Europe and more — today's student signal.

Millions of Europeans will contemplate the sky in awe on Wednesday as a rare total solar eclipse crosses part of the continent and plunges a swath of Spain into eerie daytime darkness.

Emergency workers attempting to rescue survivors after a recent earthquake in Kyushu, Japan, also had to cope with extreme summer heat.

What does it mean when brown patches show up in a perfectly healthy lawn? The truth is, it could be anything from drought to dog urine, fungal diseases, pests or too much fertilizer. But many homeowners automatically blame grubs.

When social media arrived on the scene, there were high hopes that they would improve—or even "democratize"—communication about climate change by, for instance, lowering access barriers, creating a more direct channel between science and the public, and giving more voices from ci

A University of Kansas physicist played a leading role in a CERN study showing that two rival explanations for how gluons behave inside atomic nuclei can now be experimentally distinguished.

New research introduces a contactless way to see how mirror-image materials respond differently to circularly polarized light, without first building them into a complete electronic device. The researchers developed a novel method based on light-induced charge separation that all

Fourth-year veterinary students matched—and experienced clinicians outperformed—an AI-enabled digital stethoscope in diagnosing heart murmurs and arrhythmias in cats and dogs, according to a new study from North Carolina State University. The study emphasizes the importance of hu

Modern biomedicine increasingly relies on enormous amounts of image data. Although computers can do part of the analysis work, biologists often still need to look through the images themselves. This takes time.

For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe spacecraft caught the object in a bright X-ray flare. In a

University of Bristol–led researchers have identified a naturally occurring gut molecule that could strengthen chickens' immune response against a wide range of bacterial infections. This development, published today, Aug. 12, in The Journal of Immunology, offers a major step for

Online conflict tends to advance social movements rather than undermine them, according to new research from McGill's Desautels Faculty of Management.

Signals ride on waves of one kind or another: light, sound, radio. But new carriers are needed to relay information in next-generation devices. Disturbances or waves in magnetic materials called magnons could be an efficient option—if scientists can tame them.

Place-based decarbonization schemes designed to help communities become more sustainable must involve local people earlier and consider the range of different community responses in their development if they are to be successful and gain fuller community support, researchers have

Most people underestimate how much light a pair of sunglasses blocks out. A typical dark pair removes around 80% to 90% of the visible light reaching the eye.

The use of nanoparticles in drug delivery offers key advantages: they can enable targeted drug delivery, protect active ingredients from premature degradation, extend their duration of action in the body and reduce side effects. However, as soon as nanoparticles come into contact

Before tropical cyclones can significantly strengthen, they generally must first become vertically aligned, with their rotating centers stacked through the atmosphere. New research using nearly three decades of NOAA Hurricane Hunter observations identifies four features that can

River and canal ships generate roughly a quarter of the world's shipping carbon dioxide emissions, according to new research published in Nature Climate Change. And that's despite the fact that these bodies of water make up less than 1% of Earth's total navigable waterways.

From the American West to Europe, droughts are drying up rivers, fueling destructive fires and reshaping ecosystems. They are also changing the spread of infectious diseases, leading to surges in illnesses like cholera and West Nile virus around the world.
