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

The intestines rely on different strategies to rebuild themselves in response to diet changes versus infections, according to a new Cornell study—a finding that can shed light on how gut health adapts to harsh conditions, flourishing ecosystems of microbes and variable diets.

Hundreds of previously overlooked seismic events have been detected beneath Antarctica, including 245 near the marine edge of the Thwaites Glacier. Many appear to be glacial earthquakes caused when huge icebergs break off, capsize, and collide with the glacier. The surge in activ

Strategic irrigation stress can lift lucerne seed yield and returns and more — today's student signal.

CAR T-cell therapy dramatically reduced disease activity in six people with severe rheumatoid arthritis that had resisted other treatments, with three achieving medication-free remission. The treatment may work by clearing out harmful immune cells and effectively rebooting part o

More water does not necessarily produce more alfalfa seed. A five-year trial near Keith, South Australia, found that strategically delaying irrigation until plants showed early signs of leaf drop generally increased seed yield and consistently delivered the highest gross margin.

A major new analysis challenges recent claims that the universe's expansion is slowing, finding that the evidence for cosmic acceleration remains strong. The findings preserve the leading role of dark energy, while leaving scientists with the enduring mystery of what this strange

Researchers have discovered that Western Australia’s iron-rich rocks can naturally generate hydrogen and that the process may be boosted to produce much larger amounts. If it can be scaled up, the vast formations beneath the Pilbara could become a major new source of low-emission

Earlier swathing opens a new pathway for subterranean clover seed harvest and more — today's student signal.

Subterranean clover's ability to bury its seed supports pasture persistence but makes commercial seed harvesting difficult. The industry relies on aging Horwood-Bagshaw (HB) suction harvesters, which collect seed from fully dry crops after repeated tillage and raking.

SpaceX has pulled off its biggest salvage operation yet, recovering its most recently launched Starship from the Indian Ocean.

The evolutionary histories of Earth and Mercury differ fundamentally. The smallest planet, closest to the sun, likely began cooling early on, much like a setting pudding: As early as about 1 billion years after its formation, Mercury's volcanic activity came to a halt, and a soli

Female humpback whales off the coast of Brazil now have their pick of mates, who slap the water with their tails and jostle for attention—a scene that would have been unthinkable a few decades ago.

Humans have been observing the sky for thousands of years. Our ancestors were undoubtedly fascinated by it, but observing the heavens also had practical uses: It helped people measure time, both over the course of the day and through the changing seasons, and became especially im

For generations, wheat planting has followed predictable seasonal patterns. But this year, unseasonably warm weather in March and April accelerated wheat growth, pushing the crop into a vulnerable growth stage when widespread freezing temperatures hit.

Restructuring a molecule without rebuilding it from scratch is an increasingly important goal in modern organic chemistry. Skeletal editing is an approach that helps chemists explore new chemical structures and simplify the synthesis of molecules with potential pharmaceutical app

When high or low tide occurs, the water does not necessarily rise and fall uniformly along the entire coastline. In fact, the height of the tide in a bay can vary by up to one meter (3 feet) from one location to another just a few kilometers away.

A new study suggests that El Ninos—the natural climatic chaos agent that pops up periodically and spikes global temperatures—are getting stronger because of human-caused climate change.

The intestines rely on different strategies to rebuild themselves in response to diet changes versus infections, according to a new Cornell study—a finding that can shed light on how gut health adapts to harsh conditions, flourishing ecosystems of microbes and variable diets.

Tropical Storm Karina strengthened into a hurricane in the Pacific Ocean on Sunday and could become a major storm this week, forecasters said. The cyclone's center was at far out sea and was not threatening land.

NASA's newest crown jewel blasted off Sunday to hunt for planets around other stars, explore secret dark energy and survey the cosmos like never before.

Researchers from Tokyo Metropolitan University have created a new system to test magnetohydrodynamic aerobraking for spacecraft reentering the atmosphere. Their platform generates intense magnetic fields with a powerful electromagnet as a miniature vessel is hit with a shock wave

Ancient footprints in Kenya reveal that eight Paranthropus boisei may have traveled together 1.4 million years ago, with some individuals reaching surprisingly large, human-like body sizes. The tracks offer a rare glimpse of their social behavior and suggest these extinct human r

Physicists have mathematically captured a bizarre “spacetime crystal” that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely many dimensions, potentially giving rese

On the surface, posting online reviews looks like a win-win activity. It helps both businesses we like and people who might frequent them. But although posting reviews can benefit others, it can also put us all at risk, according to new research from the McCombs School of Busines
