When cicada nymphs emerge from the ground, a certain percentage of them—between 2 and 5 percent—will acquire a fungal infection. The parasite rapidly grows inside these unlucky insects, eventually destroying whole sections of their body. But while the fungus has been known to science for a century, recent research published in the journal Nature Scientific Reports […] More
With their arresting size, cunning, and athleticism, Africa’s big cats—like lions, leopards, and cheetahs—get plenty of attention as avatars of carnivory. But the swiftest death on the sun-baked savanna comes from an animal that doesn’t look all that different from the lovable mutt snoring on your couch. African wild dogs (Lycaon pictus) are among the […] More
As our planet gets warmer, more species are being brought closer together than ever as climate bands shift polewards and key resources move along with them. When the species are closely related, the increased interaction can result in cross-breeding—as is the case between polar bears and grizzlies. But the opposite response can also be true. […] More
The coldest time of year can be a bitter inconvenience for humans, but for many species, surviving winter temperatures means wielding evolved biological tricks that appear to cheat Death itself — all of which make grumbling about donning a hat and extra layers a little trivial, in retrospect. From frozen frogs to butt-breathing turtles, here […] More
As humanity becomes increasingly interconnected across the globe, the unintentional spread of non-native species into vulnerable habitats is creating a growing crisis. Wherever they go, invasive species have the potential to wreak havoc on ecosystems and economies alike, occasionally swelling to scourge status in the absence of native predators or meaningful restrictions on their reproduction. […] More
When it comes to snakes, most of the attention goes to highly venomous varieties (like cobras and vipers) and constrictors (like boas and pythons.) This makes sense since many of these species are either quite dangerous to humans or, at least, perceived to be. But there’s a remarkable diversity of snakes and their lifestyles—and some […] More
As global temperatures rise, ecosystems and the species they harbor are adjusting in response. Many habitats are either shifting their boundaries polewards—or disappearing altogether—sending wildlife into new regions, where they interact with resident creatures in surprising and often unprecedented ways. When this geographic collision is between two closely related species, they sometimes cross-breed, leading to […] More
Every feathered thing — from the hummingbirds flitting near your feeder to the falcons that haunt lonely cliffs — has something in common, and it’s not just that they’ve got wings. Today’s modern birds descended from a single, surviving line of carnivorous, theropod dinosaurs that became small, delicate, covered in feathers, and were gifted with […] More
Thanks to tens of thousands of years of increasingly complex tools and technology at our disposal, humans have become the most apex of apex predators on this planet, doing what our hominid ancestors could not: keep ourselves from becoming food. Well, mostly. As clever as we are, humans are still very much considered morsels by […] More
When most of us think of venomous animals, we probably picture cold-blooded creatures — reptiles like vipers or cobras, deadly spiders, or maybe a tropical fish festooned with stinging spines. But there are a select few venomous mammals that also deserve recognition for their chemical weaponry. Some more famous examples include the male platypus — […] More
The word “yeti” conjures up a specific image in the folklore of Nepal and Tibet — a massive, shaggy, distinctly ape-like beast that wanders the frigid and desolate Himalayan snowscape. It certainly doesn’t evoke anything that looks like it’s about to impart wisdom about stopping forest fires. But, according to a recent study published in […] More
For humans, the allure of experimenting with intense, mind-altering substances is probably as old as our species. While certain drugs have had varying levels of legality and taboo status in some cultures, it’s hard to deny that our proclivity for taking our brains on a brief sojourn above the stratosphere is an old part of […] More
