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

Europe saw at least 30,000 excess deaths across a blistering summer of back-to-back heat waves and drought that scientists have blamed on man-made climate change, according to provisional figures.

A simple yeast-based food supplement may help restore the immune system’s ability to fight cancer, according to new research in mice. Scientists found that yeast beta-glucan reprogrammed early immune cells in the bone marrow, leading to stronger, longer-lasting cancer-fighting re

Soccer ticket crackdowns and price hikes are excluding traditional fans and more — today's student signal.

The new season of the English Premier League is almost ready to kick off, and with it comes another annual cycle of the national game. Each August brings hope and expectation for supporters, with an opportunity to start anew. But rather than excited anticipation, frustration, ang

Long polymer chains are everywhere: in synthetic materials, soft matter, biological systems such as chromosomes, and mathematical models of filaments and knots. When many such chains are densely packed, they form what physicists call a polymer melt. In this crowded environment, e

Sacramento River winter-run Chinook salmon are California's most endangered salmon, with a single surviving population and an average of a few thousand returning fish in recent decades. Shasta Dam blocks their original habitat in cold mountain rivers draining Mount Shasta, leavin

Many people are aware that the Large Hadron Collider (LHC) at CERN smashes tiny subatomic particles together at nearly the speed of light to test foundational laws of physics and discover new fundamental particles, but some experiments also help scientists better visualize the ac

Women are more likely to form close-knit friendship groups at work, a Durham University Business School study suggests. The findings are published in the journal Social Networks.

Young Bewick's swans only survive their first spring migration if they stay with their parents long enough. If they lose their parents in winter, they leave later and are unable to keep up with the rest of the population. As a result, there is a greater chance that they will die

Loughborough University physicists and an international team have demonstrated that a grain-of-rice-sized microchip can be used to produce a spectrum of precisely spaced frequencies of light, which is then converted into multiple high-frequency electromagnetic signals known as mi

A University of Staffordshire Ph.D. student has received national recognition for research that could transform how bloodstain evidence at crime scenes is analyzed. Emma Hook has been awarded the Science & Justice Review Award by the Chartered Society of Forensic Sciences for the

What a record-breaking El Niño could mean for the world and more — today's student signal.

Ammonia is one of the most important chemicals produced in the world, ranking second only to sulfuric acid in the total volume produced each year. It is used mostly to make fertilizer, which is essential to feeding the world's population. Yet its production accounts for up to 2%

Biomolecular nanomachines, such as enzymes and molecular motors, are the workhorses behind the synthesis and organization of complex materials in life. Powered by chemical energy, they build, transport and organize biomolecules, allowing living systems to create and maintain high

The surface of Mars is home to some of the most breathtaking and awe-inspiring landscapes in the solar system. This is primarily because the Red Planet lacks several resurfacing processes that Earth possesses, including plate tectonics, volcanism and flowing water.

As autumn gives way to winter across the Arctic, the ground doesn't immediately freeze solid. Instead, soils often linger near the freezing point for days or even weeks in a phase called the zero curtain. In a new NASA-led study, researchers produced high-resolution maps of the A

Europe saw at least 30,000 excess deaths across a blistering summer of back-to-back heat waves and drought that scientists have blamed on man-made climate change, according to provisional figures.

Precise activation of tens of thousands of genes is critical for healthy development and growth. Specialized segments of our DNA are responsible for carefully orchestrating genetic sequences that result in the production of enzymes, hormones, proteins and other crucial components

With Gulf turmoil slashing Suez Canal traffic, shipping firms are tempted to try the Arctic for quicker trips between Europe and Asia—but commercial prospects are unlikely to match countries' strategic ambitions for the North Pole.

Sometimes science throws up the unexpected. When a team of researchers set out to model river erosion in Canada's High Arctic, they did not expect the findings to defy common sense.

More than 6,500 years ago, someone carefully drilled a hole in a human tooth, strung it on a cord and likely used it as a necklace. Found during field surveys at the Vinča cultural site of Jablanica in Serbia, the human tooth was originally misidentified as an animal tooth bead u

Now it's the moon's turn to pull a disappearing act. After being shut out of this month's total solar eclipse, the Americas will have the best seats in the celestial house when Earth's shadow briefly envelops the moon. Almost the entire lunar surface will be masked Thursday night

People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier and becoming highly fluent were also linked to a stronger effect.

A human, an octopus, and a coral could hardly look more different—yet deep inside their cells, their chromosomes still carry recognizable pieces of a genome inherited from an animal ancestor that lived more than 600 million years ago. Since then, their chromosomes have fused, spl
