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
Robots smaller than most bacteria could deliver drugs right to the site of a brain aneurysm, preventing a devastating stroke, a new animal study suggests. The new technology has been tested only in rabbits so far. But with further study, it could become an alternative to the stents and coils that are currently used to … Read more
Believe it or not, debris from Mars has frequently made its way to Earth after powerful impacts hit the Red Planet’s surface and launch it into space. There have been at least 10 of these meteorite-forming events in Mars’ recent history. When these massive impacts occur, meteorites can be flung away from the Red Planet … Read more
There are more than 70 species of salps worldwide, with Salpa fusiformis being the most common. Salps can be found from the ocean surface down to around 2,600 feet (800 meters) deep. They are barrel shaped, ranging from 0.08 inches (0.2 centimeters) at birth to about 4 inches (10 cm) in adulthood. They can join … Read more
Researchers have developed a hair-thin battery that can power robots no larger than the dot at the end of this sentence. The zinc-air battery captures oxygen from its surroundings and oxidizes miniscule amounts of zinc, a reaction that can create up to 1 volt. This energy can then power things like sensors or a tiny … Read more
Data from India’s recent Chandrayaan-3 mission supports the idea that an ocean of molten rock once covered the moon. Scientists from the mission have published their new findings in the journal Nature. On August 23 2023, a lander called Vikram successfully touched down on the lunar surface. Controllers then deployed a rover called Pragyan, which … 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
Researchers have made a breakthrough in the race to save the world’s bananas from a devastating disease that could wipe them out, according to a new study. The bananas we eat, called Cavendish bananas, are threatened by a plant-killing disease called fusarium wilt. This disease has already wiped out other banana varieties, and it devastated … 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
