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

MDMA, also called molly or ecstasy.

MDMA Moves Closer to Approval for PTSD Treatment After New Clinical Trial

If endorsed by the FDA, the drug would become the first psychedelic approved for mental health treatment in the United States

A quarry in the Cerro Blanco Forest in southern Ecuador, which is facing threats from construction and deforestation.

Many reports of Unidentified Anomalous Phenomena (UAP) are later discovered to be some type of balloon.

NASA Report Finds No Evidence of Extraterrestrial Origin for UFO Sightings

However, no explanation can be ruled out, per the agency, which also appointed its first director of research into the subject

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

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

Dimorphos, a moonlet orbiting the asteroid Didymos, as seen by NASA's DART spacecraft 11 seconds before impact from 42 miles away.

The Asteroid Hit by NASA Seems to Be Moving Strangely, High School Students Find

After the DART spacecraft made contact with Dimorphos last year, the space rock's orbit is declining more than expected, according to preliminary research

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

The Gans' egg-eater swallows a quail egg far larger than its head.

How a Small Snake Can Eat Meals Many Times Larger Than Its Head

The egg-eating African reptile uses its stretchy jaw skin to swallow huge prey, a feat that not even a python can match

A remotely operated vehicle measured environmental conditions around the octopus nest site, including temperature and oxygen levels.

Why 'Hot Springs' Draw the World's Largest Gathering of Deep-Sea Octopuses

Some 20,000 octopuses congregate near an inactive underwater volcano off California's coast, using heat from thermal springs to hatch their eggs faster

An X-ray microcomputed tomography scan of a male Eucera bee mummified inside a cocoon.

Paleontologists Discover Mummified Bees Preserved in Their Cocoons for 3,000 Years

Some kind of "catastrophic" event, such as a sudden freeze or flood, likely killed all the young adult bees at once, according to a new study

A team including research scientists at Smithsonian's National Zoo and Conservation Biology Institute became the first in the world to successfully cryopreserve coral using a technique called isochronic vitrification.

Scientists Cryopreserve and Revive Coral Fragments in a World First for Conservation

The new freezing technique could reinvigorate corals suffering from warming oceans—or even preserve human organs in the future

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

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
