The sun is putting on a show. On Sunday the star unleashed several strong and bright solar flares, including one of the most powerful eruptions seen in decades. Far from the steadily glowing orb we sometimes picture, the sun's surface is made up of roiling plasma thrown about by twisting magnetic fields. When these fields snap, they can throw out huge bursts of energy and charged particles into spacea solar flare.

Last week AES Andesa subsidiary of the AES Corporation, an American energy companyannounced it had scrapped its plans for a sprawling, city-size renewable energy project in Chile's Atacama Desert. The Atacama offers some of the world's darkest, clearest skieswhich is why it also hosts several of Earth's most important ground-based telescopes, including those of the European Southern Observatory's (ESO's) Paranal Observatory, which could've been within a mere five kilometers of the green-energy facility, according to earlier plans.

Our iron giant is a deep space radio telescope, with an antenna dish measuring forty-six metres across, the largest instrument of its kind in Canada. Starting in the 1960s, the Algonquin Radio Observatory performed a number of cutting-edge scientific projects, including joining SETI's early efforts, in the 1970s and 1980s, to find signatures of alien life-spectrum emissions from water molecules, artificial transmitter signals. No luck.

We knew that if you inject these nanoparticles into an animal model, the nanoparticles get taken up by antigen presenting cells and this resulted in increased regulatory T-cells and decreased inflammatory disease. However, we did not know how this happens,

The Hubble Space Telescope displayed what the Universe looks like. Its successor, JWST, now reveals how the Universe grew up. Galaxies formed and grew massive swiftly: requiring under 300 million years. Larger-scale, more massive structures, like galaxy clusters, take longer. The earliest mature, fully-fledged cluster is CL J1001+0220. Simulations predict such clusters to appear late: after 2-3 billion years. However, proto-clusters, or still-forming galaxy clusters, appear far earlier.

On May 5, 1961, Alan Shepard became the first American in space. However, three months earlier NASA had launched "Number 65" on a mission that helped pave the way for Shephard's momentous flight. Number 65 was a male chimpanzee born in 1957 in the French Cameroons in West Africa. After being captured by trappers, he was sent to a rare bird farm in Florida.

Jan. 31 marks the day Ham, a chimpanzee, was launched into sub-orbital space in a Mercury capsule aboard a Redstone rocket to become the first great ape in space. On May 5, 1961, Alan Shepard became the first American in space. However, three months earlier NASA had launched Number 65 on a mission that helped pave the way for Shephard's momentous flight.

How the most massive objects in the universe first formed is one of the biggest headscratchers in astrophysics. With more advanced telescopes, astronomers have found fully formed galaxies and colossal black holes earlier and earlier in the cosmos, just a few hundred million years after the Big Bang. This shouldn't be enough time for these structures to reach their incredible size; to astronomers, it's like stumbling on a fully-grown oak tree that's only a year old.

Ever notice how the loudest person in the room often gets credited as the smartest? We've been conditioned to equate intelligence with quick comebacks, perfect grades, and the ability to dominate every conversation. But here's what psychology tells us: true intelligence often operates in the background. It shows up in the way you question things, how you process emotions, and even in those moments when you feel like you don't know enough.

CATL says its new 5C batteries will retain 80% of their capacity after 1,400 charge-discharge cycles at 140F (60C). With a theoretical range of 372 miles (600 km) per cycle, that works out to a total of 522,000 miles (840,000 km) in what CATL describes as Dubai summer heat. At a milder ambient temperature of 68F (20C), which is closer to the ideal operating temperature for lithium-ion batteries,

Specifically, I take people around downtown Seattle to explore the stone that makes up our buildings. On the corner of Second Avenue and Cherry Street is an elegant six-story structure built with two-foot-tall blocks of rough-hewn sandstone, about 44 million years old, quarried in Tenino, Washington. The building rose soon after much of downtown Seattle burned to the ground in 1889, and the jagged stone gives it a feeling of rugged permanence, certainly what the city needed after the great fire.

I don't know who invented this crazy challenge, but the idea is to put someone in a carved-out ice bowl and see if they can get out. Check it out! The bowl is shaped like the inside of a sphere, so the higher up the sides you go, the steeper it gets. If you think an icy sidewalk is slippery, try going uphill on an icy sidewalk. What do you do when faced with a problem like this? You build a physics model, of course.

It did so with the blessing of engineers at NASA's Jet Propulsion Laboratory (JPL), who decided to delegate the meticulous work of route planning to Anthropic's AI model. This involves consulting orbital and surface imagery of Mars in order to set a series of waypoints to guide the rover's movements. Once plotted, this data gets transmitted about 140 million miles or 225 million kilometers - the average distance from Earth to Mars - where it's received by Perseverance as a navigational plan.

On Thwaites itself, part of the team will try today to drop a fiber-optic cable through a 3,200-foot borehole in the ice, near the glacier's grounding line, where the ocean is eating away at it from below. Sometime in the next week, another part of the team, working from the South Korean icebreaker RV Araon, aims to drop another cable, which a robot will traverse once a day, down to a rocky moraine in the Amundsen Sea.

The Milky Way - and in fact our entire galactic neighborhood known as the Local Group - appear to be lodged in a vast, extended "sheet" of dark matter flanked on each side by cosmic voids, new research suggests. The findings, described in a new study published in Nature Astronomy, could help explain the puzzling motion exhibited by our nearby galaxies, which seems to defy the gravitational influence of neighboring realms.

A US-led research team has verified the first Mediterranean mass grave of the world's earliest recorded pandemic, providing stark new details about the plague of Justinian that killed millions of people in the Byzantine empire between the sixth and eighth centuries. The findings, published in February's Journal of Archaeological Science, offer what researchers say is a rare empirical window into the mobility, urban life and vulnerability of citizens affected by the pestilence.

Since 2021, NASA's Perseverance rover has achieved a number of historic milestones, including sending back the first audio recordings from Mars. Now, nearly five years after landing on the Red Planet, it just achieved another feat. This past December, Perseverance successfully completed a route through a section of the Jezero crater plotted by Anthropic's Claude chatbot, marking the first time NASA has used a large language model to pilot the car-sized robot.

Brain drain refers to circumstances in which highly trained experts from underdeveloped and overexploited countries migrate to wealthier international job markets. Such loss of human capital can be catastrophic for a nation's development, as a shortage of trained workers tends to strain critical sectors like healthcare and education. Now the United States government - which once fielded as many as 281,000 scientists and engineers - is experiencing a similar phenomenon.

Intensely cold air is scouring the central and eastern U.S. again and will send temperatures plummeting all the way to the tip of Florida. Along with this new Arctic incursion, a major bomb cyclone storm is strengthening off the coast of the Carolinas, potentially bringing rare blizzard conditions to the region. Some areas haven't seen this amount of accumulating snow in over 30 years, wrote the National Weather Service's office in Wilmington, N.C., on Facebook.

That seemingly paradoxical dynamic results from several factors. Foremost among them is the rebound of land beneath the Greenland Ice Sheet, a mile-thick body of glacial ice that covers 80 percent of the island and is being lost to melting at a rate of roughly 200 billion tons each year. As the ice sheet loses mass, the land beneath rises.

Sauropodshumongous reptiles with a long neck and tail and thick, elephantlike legsplayed a starring role in the dinosaur ecosystem, according to a new study. These massive dinosaurs are the largest creatures to ever walk on land. But they also played a crucial part in the food chain, the study authors write, acting as ecosystem engineers. The research was published on Friday in the New Mexico Museum of Natural History and Science Bulletin.

The reason we can gracefully glide on an ice-skating rink or clumsily slip on an icy sidewalk is that the surface of ice is coated by a thin watery layer. Scientists generally agree that this lubricating, liquidlike layer is what makes ice slippery. They disagree, though, about why the layer forms. Three main theories about the phenomenon have been debated over the past two centuries. Last year, researchers in Germany put forward a fourth hypothesis that they say solves the puzzle.
