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

Molecular memory: How a mother's age echoes in her offspring's cells and more — today's student signal.

In humans and many other animals, a mother's age can affect the physical and behavioral characteristics of the next generation. Scientists call these changes maternal age effects, and while they are widespread across the animal kingdom, researchers still don't fully understand ho

China's dominance of key green technologies is helping to subsidize the global transition to a low-carbon economy, but trade tensions could make it harder for other countries to meet their climate targets, according to a new report led by researchers at The University of Manchest

Scientists studying three artisan British cheeses found that the microbes responsible for their distinctive flavors may also offer surprising benefits for gut health. As the cheeses matured, helpful bacteria transformed their aromas and textures while potentially producing compou

Researchers have uncovered rainforest communities previously hidden within the rugged gullies of the Greater Blue Mountains World Heritage Area that are protecting vegetation not known to grow anywhere else.

Students around the world are increasingly turning to artificial intelligence tools such as ChatGPT to find answers to questions about physics, according to a new study led by researchers at Bar-Ilan University.

New research suggests that no matter what we eventually determine the last common ancestor of humans and chimpanzees to be, we'll learn it was a primate that climbed trees.

The complete genome of the tuberculosis bacterium was sequenced and published in 1998. Since then, scientists have deciphered about two-thirds of TB's genes. Or have they?

Billions of federal dollars are invested in public transportation each year, but those investments may yield greater ridership gains in smaller and midsize transit systems, particularly in the South and West, than in the nation's largest metropolitan areas, according to a new stu

"Students are funneled into echo chambers, lured into extremist content through innocent avenues such as gaming and workout videos, then exposed to extreme misogyny, racism, homophobia and transphobia." That's how one Australian teacher described what they're seeing in their clas

Humpty Dumpty had all the king's horses and all the king's men, but it wasn't enough to put him back together again. This raises the question: How many horses and men did he actually need?

A breakthrough in AI-driven crop disease detection is set to reduce harvest losses and chemical-related health risks, thanks to a first-of-its-kind tomato leaf dataset comprising almost 9,000 images.

Biologists, zoologists and psychologists have been trying to trace the origins of human language for centuries. One well-known theory, known as the social brain hypothesis, suggests that increasingly complex social lives prompted primates to evolve increasingly larger brains, whi

What if the secret to drought-resistant crops isn't how much water plants use, but when they use it? A new study identifies a daily window that could help breeders develop tomatoes that better withstand drought without sacrificing yield.

"WHALE AT ONE O'CLOCK!" Eager cruise passengers zipping around New York's southern shores rush to the starboard bow: A humpback whale is up for air, a breathtaking sighting set against Manhattan's iconic skyline.

The two largest reservoirs in the United States have fallen to record lows as a severe drought grips the country's West, according to data released over the weekend.

Borneo in Indonesia, home to pristine rainforest and protected species, is burning. Meteorologist Safillah Anggie Wahyuni hopes a solution lies in the clouds.

The threat that rising temperatures fueled by climate change pose to the health of older people has been dramatically underestimated, according to a U.S. modeling study published Tuesday.

An unstable mountain rock formation looming above the Swiss village of Kandersteg threatens a landslide that could rival the disaster that destroyed nearby Blatten last year, a collapse scientists linked to thawing permafrost and glacier dynamics.

A magnetar’s colossal magnetic field may have revealed a quantum effect predicted by Werner Heisenberg nearly 90 years ago, in which seemingly empty space alters the behavior of light. If confirmed, the discovery could offer the first direct evidence of vacuum birefringence and o

Einstein’s abandoned cosmological constant made a spectacular comeback when astronomers discovered that the universe’s expansion is accelerating. It now sits at the heart of our best cosmological model—a model that works extraordinarily well, yet may still be wrong.

Childhood criticism can leave people carrying a fear of failure long into adulthood, but new research suggests those emotional patterns may be surprisingly flexible. Young adults who revisited painful memories through imagery-based therapy showed lasting reductions in fear, guilt

The Theban Necropolis, opposite Luxor, consists of more than 400 tombs. In a new Frontiers in Environmental Archaeology study, researchers in Spain examined part of one of these tombs—chamber three in tomb TT 209—to reconstruct how this burial space was used and reused between it

People's ability to successfully navigate career changes depends on their adaptability and flexibility—skills that can be developed through training transition "muscles," according to Sarah Wittman, assistant professor of management at Costello College of Business and of industri
