The most complete skull of the extinct, flightless bird ever found has revealed adaptations that might have made the creature well-adapted for a life near water

The fern Tmesipteris oblanceolata, which scientists just discovered has the longest known genome of any organism. Ferns are known among scientists for having particularly large genomes.

This Tiny Fern Has the World's Largest Known Genome

The plant's genome has about 50 times as many base pairs as a human's, and its DNA from a single cell would stretch longer than a football field

Bufoceratias wedli, a deep-sea anglerfish

Bizarre Sex Helped Anglerfish Diversify and Dominate the Deep Sea, Study Suggests

Some of these fish perform obligate parasitism, in which males attach to—and then fuse bodies with—the much-larger females

The researchers used drone footage and tracking devices to analyze the behavior of 11 orcas in the northern Pacific Ocean.

Between Dives, Orcas Take Only a Single Breath

A new study finds the black-and-white marine mammals tend to make shorter, shallower dives compared to humpback and blue whales, making orcas the "sprinters" of the ocean

The sympathetic nervous system was thought to have evolved with jawed vertebrates. But lampreys—jawless, parasitic fish that suck out the blood of their hosts—have a simple one, per recent research.

Eerie Lampreys Hint at the Origins of Our 'Fight-or-Flight' Response and Sympathetic Nervous System

The jawless, parasitic fish largely haven't changed over the last 340 million years, but they might be better sources for studying our own evolution than thought, a recent study suggests

Measuring more than five and a half feet long and three inches thick, the fragment represents almost an entire wall of the sarcophagus.

Ramses II's Long-Lost Sarcophagus Has Finally Been Identified

An Egyptologist recently concluded that a fragment of an overlooked granite coffin bears the great pharaoh's name

Scientists trained three carrion crows to produce one, two, three or four vocalizations based on various visual or auditory cues.

Crows Can 'Count' Up to Four Like Human Toddlers, Study Suggests

Three carrion crows engaged in a simplified version of counting when prompted, and the birds showed signs of planning out their responses

A computer-generated model of Sif Mons, a volcano on Venus. The new study found evidence of recent volcanic activity at Sif Mons and the Niobe Planitia region.

Venus Might Still Have Active Volcanoes, as Recent Lava Flows Suggest 'Ongoing' Eruptions

Astronomers have again discovered evidence of recent volcanic activity on Earth's sister planet in data from the 1990s

Electrodes, placed above and below the injury, provide electric stimulation during rehabilitation, in this artist's rendering of the new Arc-Ex device.

New Device Delivers Electric Pulses to Help Patients Regain Movement After Spinal Cord Injuries

Alongside physical therapy, the electric stimulation helped patients with tetraplegia improve mobility in their arms and hands in a small trial

A greater spotted eagle soars through the sky.

Imperiled Eagles Are Altering Their Migration Routes to Avoid the War in Ukraine

Researchers found that greater spotted eagles migrated longer distances and made fewer rest stops following Russia's invasion of Ukraine in 2022, compared to previous years

An orange tributary of the Kugororuk River.

Alaska's Rivers Are Turning Orange as Thawing Permafrost Releases Metals Into Waterways

A new study identifies at least 75 Arctic streams where minerals, especially iron, are staining water with a rusty hue

Euclid’s new image of star-forming region Messier 78, a nebula that lies in the constellation Orion.

See Five Dazzling New Images of the Cosmos, Captured by Europe's Space Telescope

With its visible and infrared photography, Euclid—known as the "dark universe detective"—is helping astronomers better understand dark matter and dark energy

The soldiers fought in replicas of a suit of armor found near the ancient site of Mycenae in Greece.

Soldiers Put an Ancient Greek Suit of Armor to the Test, and It Passed

Researchers outfitted Greek marines in replicas of a Mycenaean suit and simulated combat to see if the armor was usable in its day

An illustration of the sun's magnetic fields overlaid on an image of the sun captured by NASA's Solar Dynamics Observatory in 2016.

Researchers Trace the Origin of the Sun's Magnetic Field, Shedding Light on Space Weather and Solar Cycles

In a new study, scientists suggest the sun's magnetic field originates much closer to the star's surface than previously thought, a finding that could boost predictions of solar activity

View of Jiigurru, where the pottery fragments were found

Oldest Known Aboriginal Pottery Discovered in Australia

Found on the island of Jiigurru, the 82 shards predate the arrival of Europeans by centuries, dating to between 2,000 and 3,000 years ago

The Black Death killed tens of millions of people in the mid-1300s, but scientists and historians are still trying to figure out how it spread.

Did Body Lice Spread Bubonic Plague? Research Suggests the Parasites Are Better Vectors Than Thought

These blood-sucking insects are capable of transmitting the bacteria that caused the Black Death, according to a laboratory study

Within 72 hours of a patient being admitted with a severe traumatic brain injury, doctors often ask family members to make a difficult choice about whether to continue life support.

After Brain Injuries, Doctors and Families Should Take More Time With Life Support Decisions, Research Finds

A small study suggests some severe traumatic brain injury patients can later recover a level of independence or return to their pre-injury lives

Color-enhanced transmission electron microscope images of adenovirus, which is a common cause of respiratory illnesses. Researchers identified adenovirus remnants, as well as herpesvirus and HPV, in Neanderthal remains in a new study.

50,000-Year-Old Neanderthal Bones Have Remains of Human Viruses, Scientists Find

The preliminary analysis is a first step in testing the theory that infectious diseases played a role in Neanderthals' extinction
