The hunt for life beyond Earth has taken an unexpected twist as President Barack Obama claims that aliens are real, but that he doesn't know where they are. The former president said in an interview that extraterrestrials were 'not being kept' in Area 51, a US Air Force base that has long featured in alien theories. Obama told interviewer Brian Tyler Cohen: 'There's no underground facility unless there's this enormous conspiracy and they hid it from the president of the United States.'
But on days when more staff are required to be in, office spaces can feel noticeably busier and noisier. Despite so much focus on getting workers back into offices, there has been far less focus on the impacts of returning to open-plan workspaces. Now, more research confirms what many suspected: our brains have to work harder in open-plan spaces than in private offices.
In Extended Data Fig. 8 of this article, a micrograph shown in the left column (panel AZD) was inadvertently duplicated during figure preparation. The intended image was meant to show phospho-ERK (P-ERK) levels in a MAP2K1-mutant patient-derived xenograft (PDX) exposed to the MEK inhibitor AZD6244 (AZD). However, this image was accidentally overlaid with a micrograph from Extended Data Fig. 10 (left column, panel PAN), which displays P-ERK levels in an EGFR-mutant PDX exposed to panitumumab (PAN).
The first time that University of Oxford astronomer Lyla Jung saw the cosmic configuration on her monitor, she almost didn't believe it was real. But it wasand Jung and her colleagues went on to identify one of the largest rotating structures ever found in space: a chain of galaxies embedded in a spinning cosmic filament 400 million light-years from Earth. The finding, published in Monthly Notices of the Royal Astronomical Society, may give astronomers new insights into galaxies' formation, evolution and diversity, Jung says.
The AMNH has one of the biggest dinosaur halls and exhibits-and they're iconic for a reason! The nearly complete Stegosaurus skeleton nicknamed Apex (one of the most complete ever discovered) has been on display and continues to draw crowds with its massive plates and spikes.
They are very territorial, so while it's a little early for breeding season, your little tapper could have already staked out his territory and is determined to protect it, even if he is protecting it from himself. Few creatures understand that the birds they are seeing in windows and other reflective surfaces are actually just their own reflection. So they do what's natural and peck at the intruder to scare them away.
The company is planning to launch a 1,100-pound satellite on a Falcon 9 rocket in October as part of an audacious proof of concept. The goal is to test water as the fuel for both electrical and chemical propulsion, processes that involve shooting out a stream of plasma with the use of a magnetic field and burning fuel at high temperature and pressure to generate thrust, respectively.
Argentina's deep sea holds more biodiversity than scientists previously thought. An expedition that traveled from the north of Buenos Aires province to Tierra del Fuego, the country's southernmost point, observed the world's largest known Bathelia candida coral reef, worms, sea urchins, snails, anemones, and a specimen that captured the public's attention: a rare phantom jellyfish that can grow as large as a school bus.
Men's four-person bobsledding made its Olympic debut in Chamonix, France, in 1924; women's two-person bobsledding didn't enter the Games until 2002 in Salt Lake City. Women's monobob arrived in 2022. While the earliest bobsleds were made of wood, the sport has been synonymous with steel for years, although in recent decades it has been replaced by carbon fiber, which provides greater lightness and strength.
It was the image that launched a cultural icon. In 1967, in the Northern California woods, a 7-foot-tall, ape-like creature covered in black fur and walking upright was captured on camera, at one point turning around to look straight down the lens. The image is endlessly copied in popular culture-it's even become an emoji. But what was it? A hoax? A bear? Or a real-life example of a mysterious species called the Bigfoot?
Formula 1's new era was always going to bring questions, but its first week of serious running has raised more than most. Preseason testing in Bahrain has offered flashes of performance and plenty of data, yet little in the way of firm answers about how the sport's new landscape is really shaping up. On track, the stopwatch has told a shifting story, with different teams looking quick at different moments and no clear benchmark emerging amid a game of smoke and mirrors.
The Ariane 64 flew with an extended payload shroud to fit all 32 Amazon Leo satellites. Combined, the payload totaled around 20 metric tons, or about 44,000 pounds, according to Arianespace. This is close to maxing out the Ariane 64's lift capability. Amazon has booked more than 100 missions across four launch providers to populate the company's planned fleet of more than 3,200 satellites. With Thursday's launch, Amazon has launched 214 production satellites on eight missions with United Launch Alliance, SpaceX, and now Arianespace.
After years of dismissing Earth's neighbor as a "distraction," the SpaceX CEO announced on X that the company has officially shifted its primary focus toward building a "self-growing city" on the moon. While Mars remains the ultimate goal, Musk now argues that the lunar surface offers a much faster "backup" for human consciousness. Musk pointed out that while the stars must align every 26 months for a six-month trek to Mars, the moon is available every 10 days and is only a 48-hour commute away.
The founder of Amazon, Jeff Bezos, does not often post on the social media site owned by his rival Elon Musk. But on Monday, Bezos did, sharing on X a black and white image of a turtle emerging from the shadows. The photo, which included no text, may have stumped some observers. Yet for anyone familiar with Bezos' privately owned space company, Blue Origin, the message was clear.
United Launch Alliance's Vulcan Centaur reached orbit on February 12 despite "a significant performance anomaly" that saw one of its four solid rocket boosters burn through its nozzle during ascent. Viewers of the launch from Cape Canaveral at 0422 EST (0922 UTC) were treated to some impressive fireworks as the part detached in a shower of fragments. It was the fourth launch of ULA's replacement for the Atlas V and Delta IV rocket, and the second in which an anomaly was noted with the booster.
On an empty beach at the bottom of the world, the waves that roll over the sand are midnight blue and lit by the stars and a waxing moon. I'm only vaguely familiar with the constellations that hang above Great Barrier Island, known for centuries to the Māori as Aotea, some 56 nautical miles northeast of Auckland, New Zealand. I'm not all that used to seeing them so clearly,
There is a profound, quiet magic in standing alone under a truly dark sky, but the experience becomes something else entirely when shared with a community of fellow explorers. Star parties are the heartbeat of this experience: communal, high-energy gatherings where everyone from veteran astronomers to total beginners can share a wide-angle view of the cosmos. It's a chance to level up your astrophotography skills, learn the latest in deep-space science from experts,
During viral infection and in the case of cancer, CD4+ helper T-cells release cytokines, or small signaling proteins, that activate and "give permission" to other immune cells to control and clear viral pathogens. In certain viral infections, such as lymphocytic choriomeningitis virus (LCMV), which is spread by infected rodents, CD4+ T-cells differentiate into different subpopulations, including one subset of progenitor CD4+ T-cells that replenish type 1 helper (Th1) and follicular helper (Tfh) T-cells.
Hosted at the Royal Institution, the lion, which died of old age and was then donated to science, will be dissected to demonstrate how animal biology works. Medical and veterinary students will be used to seeing such demonstrations, but doing the same for the voyuristic public might not seem very scientific, but it certainly does tick the classic idea of public demonstrations of science to educate the curious.
Cornell psychology researchers Gordon Pennycook and have won the 2026 Newcomb Cleveland Prize from the American Association for the Advancement of Science for their 2024 article about using AI to combat conspiracy theories. The association's oldest award, the prize is given to the authors of an outstanding research article published in the journal Science. " Durably Reducing Conspiracy Beliefs Through Dialogues With AI ," first published Sept. 13, 2024 in , showed that conversations with large language models can effectively reduce individuals' belief in conspiracy theories - and that these reductions last for at least two months.
"Join xAI if the idea of mass drivers on the Moon appeals to you," CEO Elon Musk proclaimed yesterday following a restructuring that saw a stream of former executives exit the AI lab. This is an interesting recruitment strategy after the company's merger with Musk's rocket maker, SpaceX, and the combined company's anticipated IPO. You might think that xAI employees ought to be fascinated with achieving AGI, using deep learning models to disrupt traditional software companies, or simply bad wordplay like "Macrohard."
