A new fresco discovered at Pompeii further muddies the already murky history of pizza and the age-old art of putting toppings on flatbread. Found in an atrium buried under a collapsed ceiling and layers of pumice and volcanic ash, the painting shows a round bun loaded with toppings and condiments next to a massive vessel of wine.Does this 2,000-year-old food item count as an early pizza?A statement from the Archaeological Park of Pompeii, which oversees the site, says that “Whilst it looks lik ...read more

Picture a giant, duck-billed, camel-backed, feathery omnivore that weighs a massive 7 tons.It may sound like a hybrid creation straight out of the Jurassic World franchise — but this creature actually roamed the Earth some 70 to 66 million years ago, during the Late Cretaceous period.  “Deinocheirus was a peculiar, humpbacked dinosaur with a duckbill-like skull that grew to Tyrannosaurus size,” says Yuong-Nam Lee, a professor at Seoul National University who helped describe new research o ...read more

The first signs of the disease are so subtle that they can be tricky to catch. Sometimes, they come in the form of rude remarks or an occasional out-of-character comment. Sometimes, they appear as a struggle to stay organized or an increase in impulsive spending. And sometimes, wrong words and slurred sentences are the initial indications. Though these symptoms can seem small, frontotemporal dementia worsens with time, transforming the way that people act and communicate. Destroying the brain fr ...read more

Rusty-patched bumble bees (Bombus affinis), are crucial pollinators of wildflowers and crops, like apples and cranberries. Named after the reddish patch on its back, the insect was listed as federally endangered in 2017.Experts estimated that numbers have declined by 87 percent in the last two decades. Before its population declined, rusty-patched bees were found in prairies, woodlands, farms, gardens and parks across the eastern U.S., the upper Midwest and parts of Canada.In a recent study publ ...read more

Researchers in Australia recently discovered a new species of demon catshark – a dusky deepwater shark with striking white eyes – by following a trail of some odd-looking eggs. Years ago, Brett Human, then a volunteer at the Western Australian Museum, came across an odd, yolk-yellow shark egg in the museum’s collection that had deep T-shaped ridges. Female catsharks incubate the eggs in their bodies for a while before sticking them to the sea floor, where they can take many months to hatch ...read more

Wild honeyguide birds and humans have hunted for honey together in Africa for centuries, if not longer. In some parts of the continent, the process starts when a hunter makes a loud, trilling “brr-hm” sound to attract the dull brown birds. They hop from tree to tree and chatter eagerly as they lead the honey hunter to a beehive in a baobab or other tree. After the human has looted the honey, the honeyguide dines on the beeswax left behind.A new study has found evidence that the famously reso ...read more

We’ve known about the colossal squid for nearly 150 years. Zoologist Japetus Steenstrup first reported on the species in 1857 after reading reports of it washing up on ocean shores. But there’s still a lot that we don’t know about it because it’s so hard to study. Its reproductive patterns, mating and hunting patterns are still largely unknown because we hardly ever see it in action. Nonetheless, ever since Twenty Thousand Leagues Under the Seas, we’ve been captivated by this supersiz ...read more

In the realm of insects, where the buzz of translucent wings and the patter of tiny feet reign, something troubling is unfolding: these small animals are quickly vanishing from the world. But how do scientists detect insects’ often silent disappearances? Because they’re tiny and often well hidden, detecting and preventing extinctions is no easy feat, explains Eliza Grames, a postdoctoral researcher at University of Nevada, Reno. “There are so many different things contributing to insect d ...read more

As Antarctica plunges deeper and deeper into winter at this time of year, the frigid continent’s surrounding lid of floating sea ice should be expanding rapidly. But this year, sea ice has been growing at an agonizingly sluggish pace that has been setting records day after day. “In the midst of its winter growth phase, Antarctic sea ice has reached a record smashing-low extent for this time of year,” according to the National Oceanic and Atmospheric Administration. “Sea ice extent is app ...read more

Sauropods that tower above treetops and tyrannosaurs that make the Earth tremble beneath their weighty footsteps are two iconic dinosaur images. These prehistoric giants have fascinated us for centuries, igniting our imagination and curiosity about the world that existed long before we set foot on this planet. Among the myriad of questions that arise when we ponder these magnificent creatures, two stand out. Why were some dinosaurs so big? How did their environment play a role in their size?� ...read more
