Some researchers say that "bringing back" woolly mammoths could help protect frozen tundras by slowing the melting of permafrost.

Scientists Grow Elephant Stem Cells in Key Step Toward Woolly Mammoth 'De-Extinction'

The team's lofty goal of "resurrection" is still far from reality, but scientists say the advancement in understanding cells could help with elephant conservation

A view of the Korolevo archaeological site. Researchers used the decay of isotopes in rocks dug up from the site to determine the age of the stone tools.

Stone Tools Found in Ukraine May Be the Oldest Evidence of Early Humans in Europe

The 1.4-million-year-old rocks may have belonged to Homo erectus, and they shed light on migrations of human ancestors, a new study suggests

Scientists conduct sampling at Crawford Lake in Ontario, Canada, in April 2023. Last summer, a working group chose the lake as a representative location for the influence of human activity on the planet due to the history recorded in its sediment.

Scientists Reject Proposal to Define the Anthropocene, a Geological Age Marked by Human Activity

Experts had suggested a new epoch started in the mid-20th century, but the recent vote demonstrates how tough it is to pinpoint when humans' impact on the planet began

An artist's rendition of the Europa Clipper mission, set to launch to Europa in October. The mission could provide new insights about the life-supporting potential of the moon, which hosts a massive saltwater ocean beneath its icy surface.

Jupiter's Moon Europa May Have Less Oxygen Than Previously Thought

The new findings could have implications for whether Europa's vast ocean contains the conditions necessary to support life

An orca hunting sea lion pups on an Argentinian beach in 2006. Before the recent study, killer whales had only been observed hunting white sharks in groups.

Single Orca Spotted Killing a Great White Shark for the First Time Ever

In less than two minutes, the marine mammal attacked a juvenile white shark and ripped out its liver in an encounter off the coast of South Africa last year

NASA SpaceX's Crew-8 from left to right: Roscosmos cosmonaut Alexander Grebenkin and NASA astronauts Michael Barratt, Matthew Dominick and Jeanette Epps. Set to launch to the ISS on Saturday, the crew will not be impacted by the leak, NASA says.

A Leak on the International Space Station Is Growing, but It Poses No Threat to Crews, NASA Says

The leak, which is at the end of a Russian service module, will not affect the upcoming launch of Crew-8 to the station

An image showing the Odysseus lander on the moon's surface. A piece of a landing leg has broken off on the left of the image. The gear still protected Odysseus as it touched down.

Odysseus Moon Lander Is Powering Down After 'Very Successful' Mission

The history-making spacecraft landed on its side, but it spent nearly a week sending data and images back from the moon—and engineers may try to make contact again after the lunar night is over

A Brazilian flea toad sits on a Brazilian real. The coin is 27 millimeters across.

The World's Smallest Vertebrate Is a Tiny Brazilian Frog, Study Finds

Adult male Brazilian flea toads are just over 7 millimeters long on average, and females measure about 8.15 millimeters

An illustration of the DART spacecraft next to the asteroid, Dimorphos, and the larger asteroid it orbits, Didymos.

Asteroid Hit by NASA Spacecraft Was Reshaped by the Collision, Study Finds

Instead of forming a crater, the agency's intentional DART crash redistributed massive amounts of the asteroid and shot large quantities of rock into space

An adult humpback whale and calf. In the new study, the researchers blew air into the larynxes of three deceased whales, including a humpback, to learn how the the organ makes sound.

Scientists Discover How Some Whales Can Sing While Holding Their Breath Underwater

Baleen whales have evolved unique voice boxes essential for song, a new study finds—but these low-frequency vocalizations must compete with the noise of humans' ships

Flaco, a Eurasian eagle-owl, sits in a tree in Central Park. The bird roosted and hunted in the park during the year following his escape, becoming popular with local birders, before his death on February 23.

Flaco, the Famous Owl That Escaped the Central Park Zoo, Dies After Hitting a Building

The Eurasian eagle-owl had been living free in New York City after someone cut the wires on his zoo cage last year

Odysseus passes over the near side of the moon after entering into lunar orbit on Wednesday. The spacecraft successfully landed on the moon Thursday evening Eastern time.

An American Spacecraft Successfully Lands on the Moon for the First Time Since 1972

After a tense touchdown process with last-minute changes, U.S.-based company Intuitive Machines received a signal from its uncrewed Odysseus lunar lander on Thursday evening

Short attention spans could be helpful for foragers, since switching quickly between food sources when exploring could lead to a higher yield, researchers suggest.

ADHD Traits Might Have Helped Hunter-Gatherers Collect More Food While Foraging, Study Suggests

Participants who self-reported ADHD behaviors were better at an online berry-picking game than those who did not report such traits

An artist's rendering of the quasar that set the record for the universe's brightest object, with its black hole at its center.

Astronomers Discover the Brightest Known Object in the Universe, Shining 500 Trillion Times as Bright as the Sun

The quasar—a glowing, active core of a galaxy—has a black hole at its center that consumes more than a sun’s-worth of mass each day

Natural gas flaring emits methane, a powerful greenhouse gas, into the atmosphere. The majority of atmospheric methane comes from human activity, with the agricultural sector and the oil and gas sector contributing the most from human activities.

New Satellite Will Track Methane Emissions From Space and Pinpoint Their Sources With A.I.

The mission, set to launch next month, comes as countries and fossil fuel companies pledge to reduce emissions of the powerful greenhouse gas

An example of the cave art found in northwestern Patagonia, Argentina. Researchers dated the paintings to as early as 8,200 years ago.

This Ancient Cave Art Passed Survival Information Across 130 Human Generations in Patagonia, Study Suggests

Dating to as early as 8,200 years ago, the paintings may have maintained collective memories during an extremely dry period in history

The proposed changes to isolation guidelines would bring the CDC's approach to Covid-19 closer to California's and Oregon's. Both states amended their isolation guidance within the last year.

CDC Considers Dropping Five-Day Covid Isolation Guideline

While no official decision has been made, symptomatic patients might be able to stop isolating if they are fever-free for 24 hours and are beginning to feel better under the proposed change

University of Nebraska engineer Sean Crimmins loads the robotic arm into its case. A surgeon on Earth will remotely guide the robot through a surgical simulation while it is on the International Space Station.

This Remotely Controlled Robot Will Conduct a Simulated Surgery on the International Space Station

Robot surgeons could treat astronauts on long space missions—but they could also be used on Earth in places where surgeons aren't present, such as rural areas or war zones

Cats can be infected with plague by flea bites or by eating infected rodents.

Oregon Resident Catches Rare Case of Plague, Likely From Their Cat

The patient was treated during the earlier stages of disease, so the community faces little risk, according to health officials

Babies might start learning the words for objects at around six to nine months old. In a new study, an A.I. was also able to match some objects to their names after getting trained on video recordings from a headcam worn by a young child.

A.I. Learns Words From a Human Baby's Perspective, Using Headcam Footage

With only limited training, the model could correctly identify certain objects, suggesting some elements of learning language are not innate to humans
