We have some incredibly powerful telescopes that have given us spectacular views of the cosmos and allowed us to look back to the early days of the universe. These observatories, such as the James Webb Space Telescope (JWST), are amazing feats of engineering that have required billions of dollars and decades of work. But what … Read more
Scientists have discovered that common AI models express a covert form of racism based on dialect — manifesting chiefly against speakers of African American English (AAE) In a new study published Aug. 28 in the journal Nature, scientists found evidence for the first time that common large language models including OpenAI’s GPT3.5 and GPT-4, as … Read more
Archaeologists in Norway have discovered a Viking Age treasure that had remained “untouched” for more than 1,000 years. The four silver bracelets had been buried nearly 8 inches (20 centimeters) in the ground on a mountainside in Årdal, a village in southwestern Norway, according to a translated statement from the University of Stavanger. “This is … Read more
Memories evolve throughout our lifetimes, changing as we learn and experience new things and as we recall a memory repeatedly. And then, memories degrade as we age. Previously, scientists thought that this malleability was the result of changes in the brain cells that originally encoded the memory, and they believed these cells stored just one … Read more
The human body does not age at a constant rate throughout adulthood — instead, it accelerates dramatically around ages 44 and 60, a new study finds. The new research, published Aug. 14 in the journal Nature Aging,involved measuring more than 11,000 molecules in the adult body over time, and it revealed that 81% of them … Read more
Researchers plan to accelerate the development of artificial general intelligence (AGI) with a worldwide network of extremely powerful computers — starting with a new supercomputer that came online in September. Artificial intelligence (AI) spans technologies including machine learning and generative AI systems like GPT-4. The latter offer predictive reasoning based on training from a large … Read more
Microscopic wormholes may be driving the accelerated expansion of the universe, scientists say. These tiny wormholes are constantly being born from the vacuum of space due to subtle quantum effects. If confirmed through experiments and observations, the wormholes could become a valuable source of information on quantum gravity — a theoretical unification of the fundamental … Read more
Vivid clouds swirl across Jupiter’s skies like colorful brushstrokes across a painting in a new photo from NASA’s Juno spacecraft. The image, taken during the spacecraft’s 61st close flyby of Jupiter on May 12, 2024, hones in on activity in the planet’s northern hemisphere. Juno was approximately 18,000 miles (29,000 kilometers) above Jupiter’s cloud tops … Read more
Scientists in China have discovered water molecules trapped in lunar rocks, upending past assumptions that the moon’s surface is dry. The rock samples, collected from the moon’s surface and brought back to Earth by China’s Chang’e 5 mission in 2020, contain crystals filled with “hydrated molecules,” according to the Chinese Academy of Sciences. Samples brought … Read more
Wild strawberries are deliciously sweet snacks, as long as you don’t mind their gritty little seeds. But why are these “seeds” on the outside, given that the seeds of many fruits — like apples, oranges, kiwis and mangos — are on the inside? It’s actually a trick question, said Aaron Liston, professor and herbarium director … Read more
