Orcas know there is strength in numbers. The whales typically hunt in packs and ambush larger prey like seals, other whales, and sea lions. But, in an odd case, researchers have recently observed orcas hunting alone — and attacking the apex predator, the great white shark.An orca could attack great white sharks for their liver, which is rich in fats, as explained in a press release by Alison Towner, marine biologist and study author. Researchers have seen killer whales attack sharks before in ...read more

In January 2024, the tidy work of a Welsh mouse, caught on video cleaning the work bench inside a man’s shed, went viral.Night after night the mouse gathered up clothespins, corks, and other miscellaneous objects, stashing them inside a rectangular wooden box for safekeeping. Each time the man laid the items back out, the mouse had cleaned them up again by the following morning.While people across the world found the video adorable, many also asked the question: Why did the mouse keep doing th ...read more

Just over five years ago, on 22 February 2019, an unmanned space probe was placed in orbit around the Moon. Named Beresheet and built by SpaceIL and Israel Aerospace Industries, it was intended to be the first private spacecraft to perform a soft landing. Among the probe’s payload were tardigrades, renowed for their ability to survive in even the harshest climates. The mission ran into trouble from the start, with the failure of “star tracker” cameras intended to determine the spacecraft� ...read more

For a brief moment in February, the world collectively held its breath upon discovering the plight of an orca pod trapped in sea ice. The frantic scene unfolded near the town of Rausu, off the coast of Hokkaido, Japan’s northernmost prefecture. According to Japanese media organization NHK, a local fisherman first contacted the town’s Coast Guard station on the morning of Feb. 6, 2024 to report an orca stuck between sheets of ice. Footage from later that afternoon revealed more orcas — abo ...read more

Astronomers may have found a dark, primordial galaxy — an enormous, undisturbed mass of cold hydrogen gas that has yet to form any stars — sitting in the modern-day universe.If confirmed, the object could offer astronomers a look at an early stage of galactic evolution. “I’ve been in this field for quite a few decades, and we’ve wanted to find something like this for a very long time,” study leader Karen O’Neil, an astronomer at the Green Bank Observatory in West Virginia, tells As ...read more

Venturing into the ocean's depths unveils a world akin to science fiction. Encompassing seventy percent of our planet's surface, the ocean potentially harbors over two million species – most of which have yet to be discovered. Beneath the surface, in realms devoid of sunlight, the cold, high-pressure environment unveils an astonishing diversity of ecosystems and animals, each uniquely adapted to thrive in extreme conditions."Animals have evolved the ability to tolerate extreme conditions,” ...read more

As you may have heard, the El Niño that has been contributing to severe weather in California and elsewhere is expected to fade between April and June. Moreover, its sibling, La Niña — which also can have a big impact on our weather — stands a good chance of taking center stage in the fall.But does this means a significant change in weather patterns will be happening soon? That's what the Weather Channel recently told its viewers: “El Niño giving way to La Niña means a warmer than aver ...read more

An ancient stone circle sits on the summit of a mountain overlooking the Cajamarca Valley in Peru’s northern highlands. At first glance, it doesn’t appear particularly remarkable — just a circle about the size of a convenience store, with a smaller circle inside. Meanwhile, what remains of its borders are made up of standing boulders.But new research has revealed that this unassuming plaza dates back nearly five millennia, to an era that far preceded the Inca and their predecessors, like t ...read more

Think of a typical creepy crawler, and you’ll probably conjure up the image of a hairy, eight-legged tarantula: the go-to spider in horror, and for those unaware, also a favorite pet among spider lovers.About 900 different species of tarantulas populate virtually every continent of our globe, save for Antarctica. They range from the tiny to the titanic, the colorful to the plain. Here are some things to know about tarantulas, who are not as scary as you’d think – as long as you don’t bot ...read more

Volcanologists can't predict eruptions. There is no reliable and tested method that can say that a certain volcano will erupt on a certain day or at a certain time. You might see such things on YouTube and elsewhere on the internet, but they are mostly people making patterns where there are none.However, volcanologists have been getting much better at forecasting eruption likelihood. Now, that might sound a lot like prediction, but it is not. Instead, it is like the weather: they can offer the c ...read more
