A Sample of Ancient Asteroid Dust Has Landed Safely on Earth

NASA's OSIRIS-REx mission retrieved bits of rock and dust from the asteroid Bennu, which could help scientists uncover the origins of life on our planet

The excavation team uncovering the wooden structure. It was unearthed along the Kalambo River in Zambia at a site called Kalambo Falls.

Archaeologists Uncover Notched Logs That May Be the Oldest Known Wooden Structure

The interlocking pieces, found near a waterfall in Zambia, date to 476,000 years ago—before Homo sapiens evolved

A Tasmanian tiger at the Hobart Zoo in Tasmania. The last known living Tasmanian tiger died at the zoo in 1936.

Scientists Collect First RNA From an Extinct Tasmanian Tiger

No other RNA has ever been extracted from an extinct species, so the breakthrough opens doors to understanding the biology of long-gone organisms

Study participants experienced cardiac arrest while in the hospital and received CPR in an attempt to resuscitate them.

Scientists Search for Near-Death Experiences of Cardiac Arrest Patients

Through survivor interviews and brain scans during CPR, researchers looked for evidence of awareness when people's hearts had stopped

Engravings at the study site depict animal tracks.

Stone Age Engravings of Animal Tracks Reveal New Details in Namibia

Indigenous tracking experts determined the species, sex, age group and leg of depicted animals in hundreds of carvings of footprints

Marc Abrahams, creator of the Ig Nobel Prizes, speaks at the 2003 ceremony. The first ceremony was held in 1991.

Smart Toilets and Licking Rocks: Ig Nobel Prizes Celebrate Strange Scientific Achievements

Winning research projects reanimated dead spiders and examined how anchovy sexual activity influences ocean mixing

A potential polar ring galaxy called NGC 4632. The composite image combines a capture of the galaxy's main disk, taken with the Subaru Telescope, with radio wave data of the hydrogen ring, which has been digitally colorized as white.

'Spectacular' Polar Ring Galaxies May Be More Common Than Thought, Study Suggests

Astronomers have found two candidates for this rare type of galaxy, surrounded by a halo of hydrogen gas—and they could provide insights about dark matter

Frank Rubio poses in front of a window on the International Space Station looking out to Earth below. Rubio has been stationed on the ISS since September of last year.

NASA Astronaut Sets Record for Longest Trip to Space by an American

When Frank Rubio returns from the International Space Station on September 27, he will have spent 371 consecutive days in space

A wild boar in Bavaria, Germany. Levels of radioactive contamination in the animals have not declined significantly since the Chernobyl disaster of 1986.

Why Germany's Wild Boars Are Radioactive

Fallout from nuclear tests conducted in the mid-20th century may contribute to the high levels of radiation seen in the animals today, a new study finds

An artist's rendition of exoplanet K2-18 b and the dwarf star it orbits. New observations from the James Webb Space Telescope support the idea that the world, discovered in 2015, has a hydrogen-rich atmosphere and water ocean.

This Exoplanet May Be a Distant Ocean World, James Webb Telescope Finds

The observatory detected evidence of methane and carbon dioxide—and tentatively observed a molecule that, on Earth, is only made by living things

Comet Nishimura, as imaged on September 7. On Tuesday, the comet will pass within 78 million miles of Earth, the closest it will get for more than 400 years.

Newly Discovered Green Comet Is Passing By Earth This Week

Comet Nishimura, which appears only once every 435 years, is on track to approach the sun and shoot into deep space

Scientists inserted human stem cells in pig embryos that couldn't develop kidneys, then let these embryos gestate in sows for several weeks. The experiments resulted in kidneys partly made of human-derived cells.

Scientists Grow Part-Human Kidneys in Pig Embryos for Nearly a Month

The new work is a "big step forward" in finding new ways to generate viable organs for human transplants, but it comes with some ethical considerations

An artist's rendering of the X-Ray Imaging and Spectroscopy Mission. The satellite will measure X-rays to deepen science's understanding of the universe. 

Japan Launches X-Ray Satellite and Lunar Lander to Space

The satellite will study large bodies in the cosmos, while the lander will attempt to land at a precise location on the moon's surface

Onlookers watch as a rocket carrying the Aditya-L1 spacecraft launches. The mission will study the sun's outer layers and the influence of solar activity on the solar system.

India Launches Mission to Study the Sun and Space Weather

The Aditya-L1 spacecraft will examine the star's outer layers and aim to shed light on its violent—and potentially damaging—storms

Smoke from wildfires in Canada blankets the New York City skyline in a haze in July 2023.

New Satellite Tracking Air Pollution Releases Its First Images

The instrument, called TEMPO, will make hourly measurements of pollutants over North America that could help reduce exposure to unhealthy air

Ann, 47, suffered a stroke that caused paralysis in 2005. The interface in the new study aims to help people who are unable to speak to communicate verbally.

Woman With Paralysis Can Speak By Thinking With a Brain Implant and A.I.

The experimental interface allows the patient to communicate through a digital avatar, and it's faster than her current system

Hogfish can change their color in less than a second to blend in with their surroundings.

How Color-Changing Hogfish Use Their Skin to 'See' Themselves

Light-sensitive proteins in the fish's skin could play a role in monitoring how they camouflage, researchers theorize in a new study

People in New Delhi celebrate India's successful landing of a spacecraft near the moon's south pole on Wednesday.

India Lands a Spacecraft Near the Moon's South Pole, a First in Lunar Exploration

No other mission has successfully touched down in this scientifically interesting moon region, which contains water ice in lunar craters

Researchers took stem cells from the healthy eyes of patients who had suffered a chemical burn in their other eye. They then transplanted the stem cells into the injured eye.

Scientists Treat Severe Injuries in One Eye With Stem Cells From the Other

Patients' own stem cells could help them recover from chemical burns that damaged a single eye, a small, preliminary study suggests

Neptune, captured by the Voyager 2 spacecraft. A new study finds a link between the planet's cloud coverage and solar activity.

Neptune's Clouds Have Disappeared, and the Sun Might Be Responsible

Scientists have linked shifts in the distant planet's cloud coverage to the ever-oscillating solar cycle, which is due to peak soon
