The fossilized remains include the most intact skull of the bird to be discovered, which helps scientists to better understand the bird's behavior, appearance and evolution.

Paleontologists Uncover Rare Skull of 500-Pound 'Thunder Bird' in Australia

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

A partially dried bed of Lake Pátzcuaro in Michoacán, Mexico. Rising temperatures and decreased rainfall are contributing to droughts in the area.

Mexico City's Reservoirs Are at Risk of Running Out of Water

Amid climate change, drought and aging infrastructure, the largest metropolitan area in North America is struggling to conserve water in a major reservoir system

A blue-eyed cicada that's on exhibit at the Field Musum in Chicago. Four-year-old Jack Bailey found the bug in his yard, and his family donated it to the museum.

People Are Spotting Rare, Blue-Eyed Cicadas Around Illinois

As two broods of periodical cicadas emerge across the U.S. this spring, people have discovered a few of the bugs that don’t have their trademark red eyes

A helicopter photographs lava and ash from the May 29 eruption in Iceland. The surrounding area has been evacuated.

Another Volcanic Eruption Hits Iceland, Launching Lava More Than 160 Feet Into the Air

It's the fifth eruption near the town of Grindavik since December, signaling a new era of volcanic activity for the region

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

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

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

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

German cockroaches took advantage of human globalization to spread all over the world.

DNA Reveals How German Cockroaches Came to Dominate the World

A new paper looks at the genes of the most common cockroach species, tracing its historical journey alongside humans, from Asia to the Middle East, Europe and beyond

Ed Dwight celebrates after landing back on Earth following Sunday morning's ten-minute flight to space.

Ed Dwight, the First Black Astronaut Candidate in the U.S., Finally Travels to Space at 90 Years Old

The former Air Force pilot trained to become an astronaut in the 1960s but was never selected by NASA. On a Blue Origin flight Sunday, he became the oldest person to go to space

Rangers clear deceased birds from Staple Island in England, where avian flu had a devastating effect on a seabird colony.

Four Important Questions About Bird Flu, Answered

The virus has killed tens of millions of birds and infected hundreds of species of animals, including dairy cattle in the United States. Here’s what you should know about it

The environment surrounding the galaxy system where the two black holes are merging. The event is occurring in the distant universe, around 13 billion years ago.

James Webb Telescope Detects Earliest Known Black Hole Merger, Just 740 Million Years After the Big Bang

The new observations could help explain how black holes became so massive in the early universe

An artist's rendering of a feathered dinosuar in the snow. Feathers would have allowed dinosaurs, ancestors of birds, to trap their body heat in cold climates.

Some Dinosaurs Evolved to Be Warm-Blooded 180 Million Years Ago, Study Suggests

Researchers studied the geographic distribution of dinosaurs to draw conclusions about whether they could regulate their internal temperatures

Tourists cool off in front of a fan in Rome, Italy on July 18, 2023. Temperatures in the area at the time surpassed 104 degrees Fahrenheit.

Last Year, the Northern Hemisphere Had Its Hottest Summer in 2,000 Years

Researchers used tree ring data to compare temperatures from as far back as 1 C.E. to 2023 temperatures

Runners compete in the Marathon des Sables, a 250-kilometer race in the Sahara Desert in Morocco, in 2022. Humans have a number physiological adaptations, such as slow-twitch muscle fibers and the ability to sweat a lot, that help with endurance running.

Long-Distance Running May Have Evolved to Help Humans Chase Prey to Exhaustion

Scientists found hundreds of recent examples from around the globe of hunters using "endurance pursuits" to tire out their prey, furthering the debate over the hunting technique

From Latourell, Oregon, the northern lights appear as ribbons of color in the night sky on May 11.

See 12 Breathtaking Images of the Northern Lights, Spotted in Shocking Places Over the Weekend

A period of unusually strong solar activity meant the colorful aurora borealis could be seen much farther south than normal

A map of excitatory neurons from the new research. The team cataloged around 57,000 cells and 150 million connections between neurons.

Scientists Imaged and Mapped a Tiny Piece of Human Brain. Here's What They Found

With the help of an artificial intelligence algorithm, the researchers produced 1.4 million gigabytes of data from a cubic millimeter of brain tissue

An artist's concept of 55 Cancri e and its sun. The star is much closer to its sun than any planet in our solar system, so it is too hot to support life.

Astronomers Discover an Atmosphere on a Hot, Rocky Exoplanet With an Ocean of Magma

It's the best evidence yet of an atmosphere on a rocky planet outside our solar system, researchers say, and studying the distant world could provide insight into Earth’s early days

An MRI of a brain of a person with Alzheimer's disease. A new study suggests having two copies of a genetic variant called APOE4 is a cause of the disease, not just a risk factor for it.

Almost All People With Two Copies of This Genetic Variant Develop Signs of Alzheimer's Disease, Study Finds

The research focused on a variant called APOE4 and largely looked at people of European ancestry—risk levels are different for other groups, the authors say
