Four protrusions appear to be arranged in pairs, each consisting of two connected branches surrounding a central depression. We really don't understand what any of these features represent anatomically.
Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.
Climate breakdown is occurring more rapidly with the heating rate almost doubling, according to research that excludes the effect of natural factors behind the latest scorching temperatures. It found global heating accelerated from a steady rate of less than 0.2C per decade between 1970 and 2015 to about 0.35C per decade over the past 10 years.
Marine fossils have been discovered on mountain ranges around the world, including the Himalayas, Andes and Rocky Mountains, which scientists say were once covered by ancient seas before being pushed upward as continents collided and mountains formed.
The remote military range near the town of Tonopah is not primarily used for nuclear detonations, but it has long been linked to US nuclear weapons programs. The site is used to test how nuclear weapons would be delivered, including experiments where aircraft drop non-nuclear versions of bombs to study their performance.
Although Kansas has no active volcanoes, the region marks the southern reach of the Midcontinent Rift System, a massive tectonic event that nearly split North America apart in Earth's distant past. When magma forced its way through the crust during that period, it left behind hardened igneous rock and deep fractures that remain buried thousands of feet underground.
The body is a shifting landscape transformed by surfaces and sensations. Each look captures a different tactile world: the heat of blood, the cool weight of metal, the yielding drift of water. The result is a sculptural study of how the elements carve, shield, and release the self. The materials we embody become the emotions we carry, and the body becomes a materialised exhibition of our emotions, from the pulse of Blood to the discipline of Metal to the surrender of Water.
It's a little-known fact that Columbia University, in Manhattan, was home to the first mining school in America-the School of Mines-founded in 1864. For the past three decades, the university's program has been mothballed. Parts of its curriculum were subsumed into the more fashionable subjects of earth and environmental engineering. But next fall, Columbia University will offer a bachelor of science degree in mining engineering once again.
The 1993 erotic thriller Sliver should have ended differently: Zeke, played by William Baldwin, was scripted to fly a helicopter towards an active volcano, after Sharon Stone's character, Carly, reveals she's the killer. The pilot, Craig Hosking, had been tasked with flying low over Hawaii's Kilauea volcano, accompanied by the director of photography, Mike Benson, and his assistant Christopher Duddy, to film the bubbling lava and white plumes of smoke escaping from the Puu Oo vent.
To capture the biological impact of this extreme environment, I used a comprehensive suite of sensors and biomarker analyses. I wore a wireless electroencephalograph (EEG) system to monitor brain activity, sleep stages and neural signatures of stress and adaptation; the Oura Ring to continuously track sleep patterns, heart-rate variability and circadian-rhythm shifts; and the glucose monitor to follow metabolic responses in real time.
Land is one of those things that can disappear even as you see it. It falls away beneath you, becoming merely the ground under your feet, because you're thinking about where you're going, or a place slowly blurring out of focus from the airplane window. Land is a primal word, primordial even, like lava. And it is a loaded word if, say, you're Indigenous or descend from a people whose land was taken from them.
For example, reader David Erickson had this on his mind: If there were aliens 66 million light-years from Earth, how big a telescope would they need to see dinosaurs? Ha! I love this question. I've thought of it myself but never worked out the mathexcept to think, Probably pretty big, which turns out to dramatically underestimate the actual answer.
During a rare break in the weather, the NYT says helicopters airlifted the researchers and their equipment 19 miles to their planned outpost site on top of the glacier. The two helicopters involved flew a dozen total loads of cargo from the icebreaker ship to the camp site, while glacial scientists and engineers erected a small tent city, complete with bathrooms, generators, and a mess hall.
My father was a petroleum geologist. A lot of my childhood, he was gone, away on oil rigs in the Powder River Basin and remote parts of Wyoming, living in man camps long before cellphones. We had to wait days to talk to him. When he went into the nearest town to shower, he'd find a payphone and call us. I was always breathless with news.

A team of geologists has found for the first time evidence that two ancient, continent-sized, ultrahot structures hidden beneath the Earth have shaped the planet's magnetic field for the past 265 million years. These two masses, known as large low-shear-velocity provinces (LLSVPs), are part of the catalog of the planet's most enormous and enigmatic objects. Current estimates calculate that each one is comparable in size to the African continent, although they remain buried at a depth of 2,900 kilometers.
Now, in a recent study published in Geology, retired University of New Mexico geologist Karl Karlstrom and his colleagues conclude that the asteroid's impact shook Marble Canyon hard enough to dislodge great chunks of stone and send a landslide tumbling into the river. The debris formed a natural dam that backed up the Colorado for over 50 miles to near present-day Lees Ferry.
The population of super-Earths and sub-Neptunes, and the origin of the radius valley that separates these two classes of planets, is best explained by cores that are made of an Earth-like composition without a substantial amount of accreted ice8,9,10,11. For sub-Neptunes, the hydrogen-rich envelope overlies the rocky core for billions of years, whereas for super-Earths, the envelope may be retained for about 100 Myr (refs. ).
With a major winter storm about to blast pretty much every US state east of the Rocky Mountains, many are scrambling to prepare for the cold, ice, and snow. And according to popular meteorology influencer Max Schuster, there's yet another winter-weather hazard to watch out for: trees exploding in the frigid air. On a viral post on X-formerly-Twitter, Schuster - who holds a meteorology degree
