New brain study reveals speech learning works differently than we thought

A new study suggests that learning and remembering speech relies more on how the brain processes sounds and sensations than on the areas that control mouth and face movements. The discovery could reshape speech therapy and help improve future brain-based communication technologies.

Meteorite reveals a lost moon-sized world from the dawn of the solar system

A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision. The discovery suggests some early planets formed from dramatically different materials than Earth and Mars, rewriting part of the solar system’s origin story.

Future astronauts could walk across rocks from deep inside the Moon

A colossal ancient collision may have left some of the Moon’s deepest secrets surprisingly close to future Artemis landing sites. By recreating the impact that formed the giant South Pole-Aitken basin—the Moon’s largest and oldest crater—scientists found that a low-angle strike from a large, iron-cored object blasted material from deep inside the Moon, including mantle rocks.

T. rex took 40 years to reach full size, scientists find

Tyrannosaurus rex may have been a much slower grower than scientists realized. A new study of 17 tyrannosaur fossils found that the giant predator likely took about 40 years to reach its full size of roughly eight tons, extending previous estimates by 15 years.

As lakes turn brown, trout and bass decline while pike and walleye thrive

Freshwater lakes across North America and Europe are becoming noticeably browner, reducing underwater visibility and reshaping fish populations. Research found that several popular sport fish, including trout, bass, perch, and whitefish, tend to decline in darker waters. Meanwhile, walleye and northern pike often become more abundant because they are better adapted to low-visibility conditions. The shift could change both lake ecosystems and the fishing experience for millions of anglers.

Think human anatomy is finished? Scientists say think again

Despite centuries of study, scientists are still finding new details and even overlooked structures within the human body. As researchers explore anatomical differences between individuals, it’s becoming clear that the body is far more complex—and less fully understood—than textbooks suggest.

The first primates may have evolved in the cold, not the tropics

A surprising new study suggests the earliest primates didn't originate in tropical forests but in cold, dry parts of North America. Some may have even survived seasonal Arctic conditions by slowing their metabolism or hibernating. Researchers found that dramatic climate shifts, rather than warmth, played a major role in driving primate evolution and expansion. The discovery reshapes our understanding of how our own lineage began.

This giant tropical fruit could help reverse gum disease damage

A new biomaterial made from jackfruit latex, pomegranate peel, and simvastatin could transform the treatment of severe gum disease. Early tests suggest it not only combats infection and inflammation but may also help rebuild lost bone and tissue around teeth.

Black hole winds may be robbing giant galaxies of their future stars

Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe’s biggest galaxies seem to have far fewer stars than expected. Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found strong evidence that supermassive black holes can unleash powerful winds that blow away the raw material needed to make new stars.

Scientists discover an earthquake gate as California faults reach their highest stress levels in 1,000 years

A new study suggests Southern California's major fault system is more stressed than at any point in the last 1,000 years. Researchers found that the Cajon Pass, where the San Andreas and San Jacinto faults meet, could act as an “earthquake gate” that determines whether a future rupture spreads across both faults. Current conditions resemble those that preceded some of the region’s largest historical earthquakes.

Could cosmic memory explain dark matter, dark energy, and black holes?

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this cosmic memory could help solve some of the biggest puzzles in physics, from black holes to dark matter and the universe’s ultimate fate.

On the brink of extinction, the vaquita gets a digital lifeline

Scientists have digitally preserved the world’s most endangered marine mammal by creating highly detailed 3D models of a vaquita skeleton using advanced imaging technology. The virtual archive provides an unprecedented look at the species and could help inspire conservation efforts before the tiny porpoise disappears forever.

Scientists say most of what’s in your food is still a mystery

Scientists are beginning to explore a hidden world of thousands of food chemicals that go far beyond the nutrients listed on nutrition labels. This “nutritional dark matter” may hold the key to understanding disease risk, healthy aging, and why different diets affect people in dramatically different ways.
