In a recent study published in the zoology journal Crustaceana, scientists working in Silent Valley National Park reported a new variety of the crab that exhibits both male and female traits. Our new crab friends, of the species Vela carli, are freshwater dwellers that hang out in the streams of the Western Ghats in India.

The new work was less notable for showing that we had found these bases in Ryugu than for solving a previous mystery: earlier studies had failed to detect them there, despite their presence in many other asteroid samples.

In Project Hail Mary, Ryland Grace, played by Ryan Gosling, wakes up in space with no memory of how he got there, highlighting the film's intriguing premise.

The tilt of the Earth's axis as it orbits around the sun causes seasons. Different parts of the world receive different amounts of sunlight depending on that angle. In the Northern Hemisphere, we experience winter from December to March, while the Southern Hemisphere soaks up the sun.

In the 1950s through the 1980s people thought of quantum effects as occurring in very small things and as a source of noise-you had to understand quantum theory to build transistors. People thought of quantum mechanics as a nuisance. He and Brassard discovered methods-like quantum coin-tossing and quantum entanglement-that turned the perceived handicaps of quantum reality into a powerful tool.

A pale spike resembling the decaying finger of a buried giant pushes up from the earth until it towers 10 feet above the ground. A massive petal-like structure unfurls to form a blood-red cape around the finger. The smell of rotting flesh fills the air. Then, some 36 hours later, the bloom is over.

The National Center for Atmospheric Research, or NCAR, provides a home for interdisciplinary and collaborative research focused on anything atmospheric. Many of the country's leading academic researchers in the field have spent time working there or have been involved in collaborations that involve NCAR.

Witnesses in Pittsburgh reported seeing what appeared to be a burning object streaking through the sky, describing it as 'a rocket or something like a meteor.' One local wrote online: '911 calls in the city. I have relatives who heard the boom from Hinckley, Ohio, all the way to Sandusky.'

A meteoroid-a small body moving through space-is called a meteor when it encounters a planet's atmosphere and subsequently produces a bright streak of light. This occurs because the meteoroid is traveling many times faster than the speed of sound.

The researchers at Eon Systems have taken several pre-existing components: a fruit fly brain scan, a tool for modelling neurons, a model of some of the fly's muscles and body, and a very simple virtual environment, connected them together and ran it. The team claims that the result displays some of the behavior of the real insect.

Cortical Labs in Melbourne taught a dish of lab-grown neurons to play Pong in 2022. Now it has built what it describes as the world's first code-deployable biological computer, running on living human tissue rather than silicon chips, which is happily playing the 1993 shooter Doom. At first it didn't know how to move, aim or shoot. Then it would shoot two enemies and stop. So it's definitely learning.

We have deployed several types of cooling systems here, each one used depending on climatic conditions. The system, created millennia ago but updated for the 21st century, works by cooling water underground in the naturally low temperatures at night. To cool water more quickly, some is also sent to the roof via solar-powered pumps and sprayed out of nozzles in a thin layer through a method known as a falling film, before draining back down underground.

The closest supermassive black hole pair, in NGC 7727, was discovered in 2021. Just 89 million light-years away, these 154,000,000- and 6,300,000-solar-mass black holes are just 1,600 light-years apart. Approximately 0.1% of young quasars are expected to be doubles, with typical separations of ~10,000 light-years.

The Titanic was one of a trio of similar White Star Line ships completed in the early nineteen-tens. In the video above, Bill Hammack, known on YouTube as Engineerguy, tells the story of not just the Titanic, but also the Olympic and the HMHS Britannic. An engineering professor at the University of Illinois, he found in the campus library issues of the journal The Engineer published between 1909 and 1911 that contain detailed photographs of the construction of both the Titanic and Olympic, sister ships that were built side-by-side.

Colossal Biosciences, valued at $10.2bn after raising hundreds of millions of dollars in funding from investors including celebrities spanning from Tiger Woods to Paris Hilton, has provoked a stampede of acclaim as well as denunciation after announcing last year it had made the dire wolf, a species lost from the world for more than 10,000 years, de-extinct via the birth of three new pups.

A core question we want to understand is where did matter come from. And then, if you know about antimatter, it's natural to ask, why is that not here? The process is not understood and we are hunting for clues as to why it happened, says Dr Christian Smorra, a physicist on the Baryon Antibaryon Symmetry Experiment (Base) at Cern.

Pi is an infinitely long decimal number that never repeats. How do we know? Well, humans have calculated it to 314 trillion decimal places and didn't reach the end. At that point, I'm inclined to accept it. I mean, NASA uses only the first 15 decimal places for navigating spacecraft, and that's more than enough for earthly applications.

Last month, scientists in Australia reported that they had taught neurons grown on a silicon chip how to play the game. The phrases 'Can it run Doom?' and 'It runs Doom' have become a popular Internet meme.

The park's namesake cave runs more than 400 miles under the earth's surface-and that's just the part that has been explored and mapped. Inside the aptly named Mammoth Cave, you'll find tube-like passageways, great rooms with sparkling walls, slot canyons, huge domes, and even a dripstone that resembles a frozen waterfall.

Superluminous supervnovae are 10 to 100 times brighter than expected, and while different theories exist, no-one is quite sure how that's possible. Now the wobbling signal from one of these super bright explosions has provided a possible answer.

The eruption generated significant heat and ash, USGS said, with some six inches of tephrabits of volcanic material, ranging from glasslike particles to rocks and ashaccumulating on a nearby golf course. Some glassy material, called Pele's hair for its strandlike structure, traveled as far as the city of Hilosome 30 miles away by car, USGS said.

The fragile-looking filaments of cooled lava known as Pele's hair can form when pockets of bubble-rich lava pull apart rapidly, experiments suggest.

The momentum enhancement factor for DART's impact was about two, meaning that the debris loss doubled the punch created by the spacecraft alone. The new study shows the impact ejected so much material from the binary system that it also changed the binary's orbital period around the Sun by 0.15 seconds.
