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

People watch Thursday's volcanic eruption in Iceland. The Icelandic Meteorological Office said Friday afternoon local time that there were no more signs of eruptive activity.

Iceland Volcano Erupts Again, Cutting Off Hot Water From Towns and Spewing Fountains of Lava

This marks the third eruption since December in a region that, prior to 2021, hadn't seen volcanic activity for centuries

A house in the Beverly Crest neighborhood of Los Angeles was pushed off its foundation by a mudslide on Monday morning. No one was in the house when the mudslide occurred. Recent storms caused at least 475 mudslides in the Los Angeles area.

California Hammered by Heavy Rains, Mudslides in Devastating Atmospheric River Storms

Some areas received as much as 13 to 15 inches of rain over a five-day period as storms felled trees, destroyed homes and killed nine people

People march in Grand Rapids, Michigan, in 2021, after police in Louisville, Kentucky, killed Breonna Taylor, a Black woman, the year before. Tawanna Gordon, Taylor's cousin, leads the march.

After Police Kill Unarmed Black People, Black Americans Lose Sleep, Study Finds

New research draws a link between unequal exposure to police violence and lack of sleep for Black adults

An entire neighborhood in Tacloban, Leyte, Philippines, destroyed by Typhoon Haiyan in 2013. More than 6,500 people died during the storm, which had maximum sustained winds of 195 miles per hour. Winds of those speeds would be above the threshold for a hypothetical Category 6 for tropical cyclones proposed by researchers.

Do We Need a Category 6 Designation for Hurricanes?

Global warming is leading to more intense storms well above the threshold for Category 5 hurricanes, scientists write in a new paper

The 23 pairs of human chromosomes. People who inherit two tall X chromosomes (bottom right) are much more susceptible to autoimmune diseases than people with one X and one short Y chromosome.

Why Do Women Get More Autoimmune Diseases? Study of Mice Hints at Answers

Four in five people with an autoimmune disease are women. New research points to an RNA molecule involved in silencing one of their X chromosomes as a potential culprit

A great white shark cruises through Atlantic waters.

Fifty Years After ‘Jaws,’ We’ve Learned a Lot About Great Whites

Though sport fishing tournaments and other activities led to population declines in the 1970s and 1980s, more recent science and conservation efforts have helped the sharks rebound

A sea otter basks in the water with some kelp. Sea otter populations plummeted as they were killed for their pelts in the 18th and 19th centuries.

Hungry Sea Otters Help Prevent Erosion on California's Coast

The marine mammals, which were once hunted nearly to extinction, feed on crabs that would make the land more susceptible to erosion by digging holes in the soil and eating roots
