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

War destroys laboratories and instruments. It also severs the human networks through which science reproduces itself. It disrupts mentorship, collaborations and informal ties that turn students into researchers.

Certain chemical substances, broadly called luminogens, have an inherent ability to emit light. Most fluorescent molecules emit light in solution but lose their emission in the solid state, where the molecules aggregate.

AI can now control fusion plasma faster than humans can react and more — today's student signal.

Princeton researchers have tested an AI system that can monitor and control fusion plasma in milliseconds, reacting far faster than a human operator. In one experiment, it predicted a damaging instability about 200 milliseconds before it appeared and adjusted the plasma to stop i

A study led by the University of Jyväskylä in Finland evaluated, for the first time, an ecological threshold for the amount of clearcutting in boreal forests. According to the results, maintaining populations of bird species specialized in old-growth forests requires either a for

Narwhals have nature's only straight tusk, a single tooth up to three meters (10 feet) long, so strange they were sold as magical unicorn horns during the Middle Ages.

An orangutan mother and her baby, threatened by wildfires encroaching on their habitat in Indonesia, were rescued earlier this week, authorities said in a statement Saturday.

Deadly floods of 2021—Researchers identify gaps in hazard mapping and more — today's student signal.

The catastrophic flooding in July 2021 claimed the lives of more than 200 people in Germany and Belgium. The high death toll makes it clear that hazard mapping and risk communication must be improved urgently. Researchers at the University of Potsdam, the Helmholtz Centre for Geo

The Etruscan painted tombs in Tarquinia, Italy, date to the first millennium BCE and are known for their vivid scenes of music, feasting, processions and the afterlife. While these tombs have been extensively studied, archaeologists have typically looked at the paintings as image

Researchers at the University of Illinois Urbana-Champaign have developed a fast, simple way to turn lignin, a plentiful plant-based byproduct of the papermaking industry, into potentially more valuable renewable chemicals.

Animals fulfill a wide range of roles in human society. They provide food, contribute to scientific research, live alongside people as companion animals, and play important roles in education, conservation, research and public engagement through zoos.

War destroys laboratories and instruments. It also severs the human networks through which science reproduces itself. It disrupts mentorship, collaborations and informal ties that turn students into researchers.

Toiling around the clock, haggard Indonesian firefighters on the island of Borneo cannot keep up with the blazes devouring landscapes and shrouding communities in a cloying haze.

When rescue dog Chloe is not tumbling across the grass on a farm outside India's tech capital, Bengaluru, she is learning to sniff human breath for cancer with a little help from AI.

About 1 million young people in the UK are not in education, employment or training (NEET). The consequences for their health and income can be significant and long-lasting, with costs to the economy as well.

A routine blood sample contains a diverse collection of immune cells that can reveal important clues about health and disease. These cells, known as peripheral blood mononuclear cells (PBMCs), are widely used to study infections, autoimmune disorders, cancer and the immune system

A large study involving more than 270,000 people has linked higher blood levels of the amino acid tyrosine to a shorter lifespan in men. Using both observational data and genetic analysis, researchers found that elevated tyrosine could potentially reduce male life expectancy by n

While the highly virulent avian influenza strain has only recently been discovered on Australian shores, researchers at Deakin University have been working behind the scenes for years, anticipating what an outbreak might look like.

Certain chemical substances, broadly called luminogens, have an inherent ability to emit light. Most fluorescent molecules emit light in solution but lose their emission in the solid state, where the molecules aggregate.

Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study published in the journal JGR Solid Earth, a group of scien

With their slender bodies and long front legs, Miracinonyx trumani—often nicknamed the "American cheetah"—was long thought to be a North American analog of the African big cat. But in a new study published in the journal Current Biology, researchers reveal that the extinct cat wa

As the electronics in our technology keep shrinking, traditional silicon-based chips are approaching their fundamental physical limits. Yet the wires connecting them might be able to shrink beyond conventional dimensions, as scientists have created one of the longest single-atom

The Pantone color of the year for 2026 is white. It's called Cloud Dancer, which is described as a "lofty white." This choice reflects a growing trend away from color in our visual world.
