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

Canine sarcoptic mange (scabies) is a skin condition in which microscopic mites (Sarcoptes scabiei) infest dogs' skin. The condition is contagious and zoonotic and can be difficult to detect. If left untreated, it can cause bleeding sores, malnutrition, emaciation and secondary b

A recent National Student Safety Survey found that one in six students attending Australian universities had been sexually harassed and one in 20 had been sexually assaulted since starting university.

Scientists are increasingly relying on powerful data sources and tools that they often cannot fully understand, inspect or verify, according to a new study.

The false and the furious: We aren't just bothered by different beliefs—we're bothered when we think others are wrong and more — today's student signal.

Why do disagreements about vaccines, climate change or elections often feel so personal? Our research suggests it is not simply because other people have different beliefs. It is because we think those beliefs are mistaken.

Firefighters raced to save a 1,000-year-old monastery in northeastern Spain on Friday as a growing wildfire prompted the hasty removal of the bones of medieval monarchs buried there.

For centuries, scholars have read ancient documents describing the production of brass in 10th-century A.D. China. The problem was that the earliest physical evidence of brass production would be found nearly 600 years later, in the 16th century A.D.

Adjusting to a new time zone or work schedule can leave the body's internal clock out of sync for days, contributing to sleep disruption, metabolic changes and other health consequences. Researchers at Rice University and Northwestern University have developed an implantable cell

Respiratory infectious diseases and air pollution remain persistent global health challenges. Yet the tools used to monitor airborne threats are often expensive, power-hungry and difficult to deploy outside laboratories.

Iron is essential. Our cells need it to produce energy, carry oxygen throughout the body and power countless chemical reactions that sustain life. But this metal has a dark side. When too much of it is left free inside cells, it can trigger destructive reactions that break down D

Whether on lunch break or on the clock, many employees scroll through the news and social media during the workday. Researchers found that employees who "doomscroll" at work suffer hidden costs that extend beyond lost productivity.

Women who used estrogen-only hormone therapy later in life were less likely to develop dementia and showed fewer signs of Alzheimer’s disease in their brains, according to a large study of more than 21,000 participants. Hormone therapy use was linked to 39% lower odds of a dement

A recent National Student Safety Survey found that one in six students attending Australian universities had been sexually harassed and one in 20 had been sexually assaulted since starting university.

Tiny viruses that infect bacteria could one day help us tackle infections that antibiotics can no longer treat. But first, scientists need to understand how these viruses work, and artificial intelligence could provide them with a powerful way to do that.

When a dairy cow miscarries, a farmer loses far more than an unborn calf. Feed has been grown, land and water have been used, and greenhouse gases have been released during the cow's pregnancy, but milk production, a future animal and income are lost.

NASA is planning to send three small rovers to the moon with a single instruction: Work out among yourselves how to explore a patch of ground.

Canine sarcoptic mange (scabies) is a skin condition in which microscopic mites (Sarcoptes scabiei) infest dogs' skin. The condition is contagious and zoonotic and can be difficult to detect. If left untreated, it can cause bleeding sores, malnutrition, emaciation and secondary b

A new paper published in Physical Review Letters reveals that a leading dark matter candidate—the hypothetical "dark photon"—would not have heated the early universe as previously thought. The finding opens a vast region for experimental searches and could change the hunt for dar

Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all satellites orbiting the planet while orbiting retrograde

Fossils collected in Osaka more than 30 years ago have revealed a surprise hiding in plain sight: four previously unrecognized bones from a giant Cretaceous mosasaur. Among them is the first confirmed premaxilla—the frontmost bone of the upper jaw—ever identified in a Japanese mo

A widely available food-preservation chemical is emerging as a disturbing factor in rising UK suicide deaths, particularly among younger people and men. Researchers say the scale may be underestimated and are calling for urgent restrictions on access and harmful online informatio

Scientists have long thought an unusual genetic system helped ants, bees, and wasps evolve their extraordinary social colonies. A massive new analysis suggests that genetics alone can’t explain it—and the real secret may lie in other traits unique to these insects.

Fusion reactors, devices that generate energy by fusing light atomic nuclei at extremely high temperatures, could contribute to ongoing efforts aimed at producing electricity more sustainably. The extreme environment inside these devices, however, can damage materials that surrou

Over the past two decades, photonic-crystal surface-emitting lasers (PCSELs) have shown promise as a type of advanced semiconductor laser useful in defense- and aerospace-related applications. Typically, these devices are made with photonic crystal patterns that repeat across the
