Data from the Hubble Space Telescope unveils new information about this mysterious visitor

Golden apple snails and humans have similar eyes with related structures. Understanding how the snails can regrow them could help scientists heal human eyes.

This Snail Can Regrow Its Eyes—and Understanding How May One Day Help Humans With Injuries

Researchers pinpointed a gene related to eye development in golden apple snails, which can regenerate amputated eyes within about a month

An illustration of E. coli. Scientists have been racing to shrink the genetic code of this bacterium.

Scientists Rewrite the Genetic Code of E. Coli, and It’s Drastically Different From Anything Found in Nature

The synthetic bacteria contain a shorter genetic code with 57 codons rather than 64, freeing up space for further edits that might lead to new drugs or virus-resistant microbes

Australia’s major skink (Bellatorias frerei) has evolved to combat snake venom with the same mutation found in honey badgers, according to a new study.

Scientists Discover Australian Lizards Have Mutations to Resist Snake Venom—and One Day, That Could Help Humans

A new study looking at how skinks have evolved to block venom from reaching their muscles could guide development of new antivenoms

The study found that regular exercise, along with other lifestyle changes, can slow cognitive decline in older adults.

Cognitive Decline Can Be Slowed Down With Lifestyle Changes, From Diet to Exercise and Social Time, New Study Suggests

A 2,100-participant clinical trial found that structured and self-guided lifestyle changes can improve cognitive capabilities in older, at-risk adults

After seeing a picture of the stick insect on social media, the researchers spent days trying to find and collect it for further research.

Gigantic ‘Walking Stick’ Discovered in Australia Might Be the Continent’s Heaviest Insect

Scientists identified the elusive new species from a female found in a high-altitude rainforest’s canopy

A fateful meeting between ancestors of tomatoes and potatoes allowed for the growth of tubers, the edible part of potatoes today, according to a new study.

The Potato May Have Evolved From a Tomato Ancestor Nine Million Years Ago, Genetic Study Suggests

A genome analysis indicates wild tomatoes and a potato-like plant called Etuberosum hybridized to create the modern potato

Seeing a potentially infectious person might kickstart the body's immune system, according to a new study.

The Mere Sight of Someone Sick Triggers an Immune Response, Study Suggests

Researchers equipped study participants with virtual reality headsets and observed how their brains and immune systems reacted to avatars with signs of illness

Scientists filmed the way killer whales hunt together. These images show one of the animals turning toward the other after a tail slap delivers a shock to herring.

Killer Whales Hunt Fish in Highly Coordinated Pairs and Perfect Their Movements With Practice, Drone Videos Reveal

Footage taken off the coast of Norway reveals that orcas team up to maximize their prey, according to a new study

Researchers found fragments of fossils representing prehistoric mollusks, crustaceans and worms among rocks at the Grand Canyon.

Trove of Fossils Uncovered in the Grand Canyon Offers a Rare Glimpse Into Cambrian Life, With Toothy Worms and Slug-Like Mollusks

Rocks found along the Colorado River in Arizona turned out to contain fossilized fragments of soft-bodied creatures, suggesting the site may have been an “evolutionary hotbed”

The Perseid meteor shower in 2023. Although the prolific shower is not currently at its peak, astronomers recommend catching a glimpse before the moon gets too bright.

How to Watch This Week’s Stunning Dual Meteor Shower and More Upcoming Celestial Events

You can catch meteor showers and a special lunar display early this week, and keep an eye out for the popular Perseids

Early detection cancer tests are showing signs of promise, but some researchers still have reservations.

Cancer DNA Can Be Detected in the Bloodstream Up to Three Years Before Diagnosis, Study Suggests

For a few individuals, scientists found genetic material from cancerous tumors in blood samples taken years before they were diagnosed through traditional methods

A screenshot from the CCTV footage reveals the moment when the ground moved.

CCTV Footage Captures the First-Ever Video of an Earthquake Fault in Motion, Shining a Rare Light on Seismic Dynamics

A clip recorded in Myanmar in March reveals a curved path of the fault slip, which can help scientists better understand the physics of such events

The ice cores were collected from East Antarctica's Dome C and are now being held in a freezer room at the British Antarctic Survey.

Scientists Will Melt the World’s ‘Oldest Ice’ to Reveal Its Secrets and Uncover a Climate Record of 1.5 Million Years

The ice cores could offer clues about a period known as the Mid-Pleistocene Transition that has long puzzled scientists

Scientists observed the faint companion star, shown in blue, by using a speckle imager mounted on the Gemini North telescope in Hawaii to capture several short exposures.

Astronomers Say They’ve Finally Spotted Betelgeuse’s Companion Star, Long Predicted to Exist but Never Seen

The discovery, if confirmed, could explain Betelgeuse’s mysterious six-year oscillations in brightness

The push and pull between the Earth and its moon impacts our planet's rotation.

Today Will Likely Be Shorter Than Usual, and It Will Happen Again in August. Here’s Why

Because of the moon’s position, Earth is rotating just over a millisecond faster than usual on a few days this summer

An artist's reconstruction of the giant ichthyosaur Temnodontosaurus (left), featured in the study, and researchers examining part of the creature's flipper at Sweden's Lund University (right).

Fossil Flipper Reveals Ichthyosaurs Hunted in Lethal Silence With Unique Adaptations for Stealth

An analysis of a roughly 180-million-year-old fossil fin reveals serrations and flexibility that might have served to dampen sound as the predator swam

The meteorites could open up a new avenue to understand Mercury, pictured, which is notoriously hard to study due to its proximity to the sun.

Scientists Have Never Confirmed a Meteorite From Mercury. Could These Space Rocks From the Desert Be the First?

Two meteorites found in the Sahara show tantalizing similarities to the innermost planet, and while researchers say they are likely not direct samples, “one cannot rule out” the idea
