Why Are Giant, Ancient Tropical Trees Dying?

Scientists from an international project are racing to figure out what kills these anchors of their ecosystems—before it's too late to save them

A woman stands behind a model of a Neanderthal at the Natural History Museum in London. Contrary to the narrative that early humans left Africa roughly 50,000 years ago, a new study finds our species migrated from the continent on multiple occasions.

Early Humans Migrated Out of Africa Several Times, DNA Study Suggests

Homo sapiens interbred with Neanderthals as early as 250,000 years ago and may have ultimately bred them out of existence, according to new research

Scotty, the largest T. rex specimen on record, is on display at the Royal Saskatchewan Museum in Canada.

The Largest T. Rex Could Have Been 70 Percent Heavier Than Fossils Suggest

Two scientists used modeling to predict how big the giant carnivores could have really grown, making a point that fossils likely don't represent the largest or smallest individuals of a species

A team of archaeoastronomers suggests the Pyramid of the Moon in Teotihuacán, Mexico, may have been constructed to align with the movement of the sun.

Ancient Mesoamerican 'Pyramid of the Moon' May Align With Summer and Winter Solstices

New research suggests the monument in Teotihuacán, along with the larger Pyramid of the Sun, were designed based on astronomical movements

A coating of iron on Komodo dragons' teeth could help keep them sharp for tearing into prey, as well as protect them from digestive acids.

Komodo Dragons Have Iron-Coated Teeth, Study Finds

New research provides the first evidence of the adaptation in a carnivorous reptile, and it might hold clues to understanding the teeth of dinosaurs

In the future, blood tests could aid in shortening wait times for people seeking care for cognitive symptoms.

Alzheimer's Blood Test Outperforms Standard Diagnostics in New Study

The blood test accurately diagnosed Alzheimer's around 90 percent of the time, compared to 73 percent for specialists and 61 percent for primary care physicians

An artist's impression of the shrew-like Krusatodon kirtlingtonensis, which a new study suggests lived long and matured slowly, in contrast to modern small mammals.

Two Rare Jurassic Skulls Could Help Unlock the Secrets of Mammals' Evolutionary Success

Fossils reveal a prehistoric, mouse-like creature matured slower and lived longer than similar mammals of today

An illustration of the taco-shaped Odaraia, which researchers say likely swam upside-down and trapped prey in its spine-covered legs.

Taco-Shaped Creature Had a 'Major Edge' in Evolution—and 30 Pairs of Spiny Legs

This shrimp-like arthropod was among the first to have a mandible, and it used a complex feeding mechanism during the Cambrian explosion, according to a new study

Gerard Barron, chairman and CEO of The Metals Company, holds a nodule retreived from the seafloor in the Clarion Clipperton Zone of the Pacific Ocean in 2021. The company plans to mine for these nodules, which researchers suggest produce oxygen underwater.

Scientists Discover 'Dark Oxygen' on the Ocean Floor Generated—Surprisingly—by Lumps of Metal

Researchers found that electric currents from polymetallic nodules are behind this alchemy—the same minerals that deep-sea miners are targeting

Dogs are highly attuned to the emotions of humans, according to the results of a new study about stress.

The Smell of Human Stress Leads Dogs to Make More Pessimistic Decisions, Study Suggests

Canines that smelled the sweat of anxious people were less likely to approach a bowl that might have contained food, indicating humans' emotions can affect dogs' behavior

Project leader Laura Cinti visited the Wood's cycad at Royal Botanic Gardens, Kew, in London.

The 'World's Loneliest Plant' Could Soon Find a Mate With a Little Help From A.I.

The only known wild Wood's cycad was discovered in 1895, and it has since been cloned into many male trees. Now, researchers are scouring a forest in South Africa for an elusive female specimen

The Brazilian sharpnose sharks were purchased from fishers between September 2021 and August 2023.

Thirteen Sharks Test Positive for Cocaine Off the Coast of Brazil

All of the wild Brazilian sharpnose sharks tested in a new study had the drug in their bodies, but many questions remain about cocaine's effects on aquatic creatures—and the humans who eat them

Two chimpanzees at the Budongo Conservation Field Station in Uganda

Chimpanzees Take Turns in Fast-Paced Conversations, Just Like Humans Do

A new study finds the average chimpanzee response time in gestured conversations is 120 milliseconds, which isn’t that far from the human average of 200 milliseconds

A thin slice of the ancient rocks collected from Gakkel Ridge near the North Pole, photographed under a microscope and seen under cross-polarized light

Geologists Uncover Remnants of Earth’s Mantle That Have Lasted Over 2.5 Billion Years

New research suggests that a discrepancy in rocks shows they endured extreme heat, and reveals more about an ancient part of our planet’s history

Researchers experimented with venom from red spitting cobras (pictured here), as well as black-necked spitting cobras.

Common Blood Thinners Could Combat Snakebites, Preventing Tissue Damage and Amputations, Study Finds

An estimated 400,000 people per year are permanently disabled because of snake venom, which can cause lesions and necrosis at the bite site

A heat map of brain activity shows stable patterns before and after taking psilocybin in blue and green, while temporary changes are shown in red, orange and yellow.

See How the Brain Responds to Psychedelic 'Magic Mushrooms'

A new study mapped large, temporary changes in brain areas related to introspection and one's sense of self, after participants took a dose of the drug psilocybin

The ruins of Pompeii with Mount Vesuvius in the background. The city was destroyed during an infamous volcanic eruption in 79 C.E., and new research suggests an earthquake may have contributed to the damage and death toll.

Amid Its Volcanic Eruption, Pompeii Was Also Rocked by an Earthquake, Study Suggests

Researchers uncovered skeletal remains of two people in the ancient city that seem to have been killed by a building collapse caused by seismic activity

A reconstruction of a giant armadillo in the collection of paleontology at the Museo de La Plata in Buenos Aires, Argentina

Was This Giant, Armadillo-Like Animal Butchered by Humans in Argentina 21,000 Years Ago?

The creature's bones show evidence of cutting with stone tools, adding to a series of findings that suggest humans were present in the Americas earlier than thought

A pit in the Sea of Tranquility, captured by NASA's Lunar Reconnaissance Orbiter.

Scientists Find an Underground Cave on the Moon That Could Shelter Future Explorers

Such caves could serve as lunar bases during upcoming missions, protecting astronauts against cosmic radiation and extreme temperatures

A prototype of the system for collecting the astronauts' urine. In the future, astronauts may go on longer spacewalks that will require them to carry more drinking water.

Spacesuit Prototype Turns Pee Into Drinking Water

The system is inspired by the stillsuits for collecting moisture in the science fiction epic <em>Dune</em>
