Researchers from the University of Texas (UT) Austin recently announced the discovery of a new aetosaur species. These prehistoric relatives of modern crocodiles, which ruled the world before dinosaurs, came in many shapes and sizes. The heavily armored creatures went extinct around 200 million years ago. However, their fossils can still be found on every continent except Antarctica and Australia....

This past weekend, the Sun let its presence be felt by unleashing a series of massive solar flares. The resulting auroras were visible across the Northern Hemisphere and even parts of the Southern Hemisphere, treating stargazers to a rare and breathtaking spectacle....

A Sumatran orangutan named Rakus has stunned researchers by treating a cheek wound with a medicinal plant. The male primate, believed to be about 35 years old, lives in Gunung Leuser National Park in northern Sumatra, Indonesia. The protected rainforest is home to over 750 animal species, including 150 orangutans....

Sixteen US states, stretching from Maryland to Oklahoma and Illinois to Alabama, are bracing for the arrival of trillions of noisy cicadas. What makes the event especially rare is that two broods are emerging simultaneously. Brood XIX, comprising four species that surfaces every 13 years, and Brood XIII, consisting of three species that appears every 17 years. This unusual coincidence last occurred 221 years ago, in 1803, and won't happen again until 2245....

On April 21, 2024, the 10.5-mile-wide (17 km) Comet 12P/Pons-Brooks, also called "Devil Comet," will make its closest approach to the Sun. As it comes near the star, the comet will brighten significantly and be visible in the western sky an hour after sunset. The icy rock will appear as a fuzzy glowing patch with a faint tail streaking behind....

Humans and chimpanzees share 98.8 percent of their DNA, so it's not surprising that they display similar behaviors and traits. They include communicating through gestures and vocalizations, and using tools to complete tasks. Now, new research reveals that chimpanzees employ human-like military tactics to evaluate risk and expand their territories....

Here is some exciting news for those who missed the solar eclipse on April 8, 2024. Between now and September, NASA predicts an even rarer celestial event — a nova outburst. Unlike the eclipse, this phenomenon can be observed from anywhere on Earth without using any special equipment....

In a world first, doctors at the Massachusetts General Hospital (Mass General) in Boston have successfully transplanted a genetically modified pig kidney into a living person. The March 21, 2024, announcement came just months after the successful completion of similar transplants in deceased individuals. The historic four-hour surgery took place on March 16, 2024. The 15-member transplant team included experts who had spent their entire careers working on organ research....

On April 8, 2024, millions of people across Central and North America will be treated to a spectacular total solar eclipse. The celestial event comes seven years after the "Great American Eclipse" of August 21, 2017 — the first total solar eclipse visible from coast to coast since June 8, 1918. For those who miss the April 2024 show, the next chance to see the spectacle will be August 12, 2045....

In the summer of 2023, Lohit Y.T. and his team at the World Wildlife Fund-India traveled to the foothills of the Western Ghats in Karnataka, India. They hoped to research the area's amphibians and reptiles, which often emerge during the humid monsoon season. While documenting a cluster of about 40 Rao's intermediate golden-backed frogs near a small pond, the naturalists noticed something unusual. One of the amphibians had a mushroom sprouting from its side!...

What if you could transform the plastic spoon you used at lunch into a cup for your water and then change it back to a spoon? That is precisely what researchers at the University of Chicago's Pritzker School of Molecular Engineering had in mind when they created "pluripotent plastic."...

A novel gene therapy is bringing hope to children born with a specific type of hereditary deafness. On January 25, 2024, researchers at China's Fudan University and Harvard Medical School (HMS) announced that the groundbreaking treatment had restored the hearing of five of the six test patients....

Methuselah, a female Australian lungfish at San Francisco's Steinhart Aquarium, has always been a favorite with locals. But she has achieved global fame since September 2023, after scientists announced that she was at least 93 years old, making Methuselah the world's oldest living aquarium fish. The title was previously held by Grandad, an Australian lungfish who lived at Chicago's Shedd Aquarium. He was believed to be between 109 and 115 years old when he died in 2017....

As far as anatomy goes, there have been few animals as puzzling to researchers as the starfish. Most animals have easily identifiable heads, bodies, and legs. However, starfish bodies are made up of five identical arms with a layer of "tube feet," to help them propel forward. The lack of a discernable head led some to even suggest they did not have one. But, a new study asserts that the opposite is true. The sea star's body is just one big head and no tail!...

Adult Chinstrap penguins love their naps. A recent study found that the flightless birds take as many as 10,000 naps a day when nesting! Each snooze lasts about four seconds, adding up to a total of 11 hours. But at no point do the penguins fall into deep sleep....

Evaporation has long been thought to happen only when a liquid absorbs enough heat to turn into vapor. However, researchers at the Massachusetts Institute of Technology (MIT) recently found the process can also occur in the presence of just light....

About 4.5 billion years ago, a Mars-sized planet smashed into the newly-formed Earth. The collision ejected a large amount of planetary debris into space. Scientists believe that due to the energy from the impact, the debris was initially molten. It solidified over time as the material cooled and eventually became the Moon. However, how quickly that happened is up for debate....

On January 8, 2024, the world witnessed a remarkable effort by NASA and Pittsburgh-based Astrobotic Technology to land a spacecraft on the Moon. It was the first US attempt at the lunar surface since the Apollo 17 mission in 1972. The Peregrine Lunar Lander was launched into Earth's orbit without a hitch. Its final destination was an unexplored area on the western rim of the Moon's largest impact crater....

When it comes to brainpower, bottlenose dolphins are second only to humans. The intelligent animals are known to use tools, help fellow dolphins in distress, and even prepare their food to make it more palatable. Now, a new study has found that just like humans, dolphin moms change their voices when "talking" to their young ones....

In a medical breakthrough that could save thousands of lives, surgeons at NYU Langone Health reported that a pig-to-human kidney transplant had worked for two months. This is the longest period a genetically modified pig kidney has functioned in a human....

2023 was a remarkable year for dinosaur fossil finds. Paleontologists across the globe unearthed a myriad of well-preserved remains, providing new insights into the ancient giants that roamed Earth millions of years ago. Here is a short list of some of the amazing and important finds made in 2023....

With the days getting increasingly shorter and colder, it may appear that winter is already upon us. However, the astronomical start of the chilly season in the Northern Hemisphere will not be until December 21, 2023. Often referred to as the winter solstice, it marks the shortest day and the longest night of the year. Conversely, Southern Hemisphere residents will celebrate the summer solstice on this day. They will enjoy the longest day and shortest night of 2023....

There are over 30 meteor showers throughout the year. But most of them pale in comparison to the Geminids. Nicknamed the "900-pound gorilla of meteor showers" by NASA, they outweigh other dust streams by factors of between 5 to 500! The "shooting stars" are also easier to see because they go through the skies at about 22 miles (35 km) per second. This is almost half the speed of the Perseid meteors, which zip past at 37 miles (60 km) per second....

Anti-bird spikes are commonplace in urban cities. The sharp pins and poles fitted on rooftops are meant to prevent birds from perching or nesting on buildings. But in an ironic turn of events, some intelligent birds are ripping out the metal rods and using them to build nests....
