The adaptable pterosaur – the first flying vertebrate – lived in dark, polar conditions in what is now Australia, according to a new paper. The research identified two pterosaur bones more than 30 years after their initial discovery.The bones date to 107 million years ago, during the Cretaceous Period, when Australia formed a large southern landmass with Antarctica, New Zealand and South America. At that time, the Australian state of Victoria – where volunteers first found the fossils in t ...read more

The portrayal of a narcissist is everywhere in movies, books and even crime documentaries. Some of these archetypes are compelling. If you try to poll people on the streets on how they define a narcissist, they may come up with a string of flowery names such as self-centered, egotistic, vain, cocky and so on. In psychology, the term narcissism describes someone who has “an excessive love or admiration of oneself, often to the detriment of others,” says licensed psychotherapist Annie Wright � ...read more

Europeans had never seen a hummingbird when they first arrived in the Americas. Because of their petite size and vibrant, beautiful coloring, they called the birds Joyas voladoras — flying jewels. Delicate as they are, they don't let their small size get in the way of being bold and unique in the animal kingdom. Here are some interesting facts about the world's favorite J. voldoras. Types of Hummingbirds(Credit:Ondrej Prosicky/Shutterstock) Of the over 330 species of hummingbirds worldwid ...read more

Some 1.7 billion Tyrannosaurus rex dinosaurs once roamed the earth, according to a new paper. But that wasn’t all at once – the paper’s model estimates that only 19,200 were alive at any one time, a more fitting number considering their role as top predators.The study follows research from 2021 that pegged the total number of T. rex dinosaurs at 2.5 billion. But the new paper’s author, Eva Griebeler – an evolutionary ecologist at the Johannes Gutenberg University Mainz – revised key ...read more

The skip in the human footstep – the flexing of the arch with each step – does little to help carry the body forward, a new study has found. Instead, it serves to keep the ankle upright, so that we walk in the characteristic way of human beings and not like other apes.The finding overturns conventional wisdom and may help in the treatment of people whose arches have become rigid due to illness or injury.“We thought originally that the spring-like arch helped to lift the body into the next ...read more

The Paleozoic Museum in Central Park was sure to be spectacular. The 1868 plans for the museum imagined an immense and sophisticated space filled with fanciful dioramas of dinosaurs and other ancient animals, all intended to incite a passion for paleontology in its visitors.But in May 1871, the models that were made for the museum were destroyed by a band of sledgehammer-wielding workmen. The incident was one of the most strange and startling moments in the history of paleontology. And as the sm ...read more

The Moonrush has begun. Last year, NASA’s Artemis 1 mission flew to the Moon and back in a test of the technology that will take humans back to the surface in the next few years. The Artemis program will establish a space station called the Lunar Gateway in orbit and a base on the surface. There will be other visitors too — both Russia and China are planning crewed missions. And some 30 uncrewed missions are in various stages of completion by spacefaring nations and private companies.All tha ...read more

Imagine you're a leech in one of the lush rainforests of Southeast Asia (or Madagascar or mainland Africa) that you call home. Perhaps you're clinging to the underbelly of a low-lying plant or burrowed just below the surface in a patch of damp soil. Then, dozens of human tourists start marching through the terrain, providing countless opportunities for you and your companions to suction yourselves onto their boots, or drop down from the trees above. Surely, for the leeches, large groups of human ...read more

Snow leopards are so rare that many of the researchers who have studied them for decades have never even seen one in the flesh. These big cats may leave scat or even the occasional tuft of fur in a hair snare, but their passage is often ghostly — so much, in fact, that photographers are only just now capturing many aspects of their lives. In many areas, snow leopards still face conservation threats due to mining development, livestock herding and persecution from locals in their range.Snow Leo ...read more

In 1346, Tartar leader Khan Janibeg laid siege to a Genoese city in Crimea called Kaffa in hopes of removing the Italians from this central foothold. What happened next has become part-legend, part-historical record: As the Tartars waited outside Kaffa’s walls, the soldiers began to fall one by one to a terrible disease, the plague.Out of frustration, the Tartar leaders catapulted the disease-ridden bodies over the walls of the city, where the residents threw the bodies aside and fled in ships ...read more
