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
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
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
Considered one of the most famous Neolithic monuments in England, this table-shaped dolmen consists of nine upright large stones that are topped by one massive capstone weighing approximately 28 tons (25 metric tons), according to English Heritage, a charity organization that oversees hundreds of historic sites in England. As early as the 13th century, people … Read more
Earth’s days once got more than two hours longer, thanks to the moon drifting thousands of miles farther away in its orbit over two periods, researchers have discovered. The extra hours of sunlight, in turn, may have led to oxygenation events that ushered in a period when life’s complexity exploded, the study researchers say. “Daylength … Read more
he world’s oceans are home to microscopic organisms invisible to the human eye. The tiny creatures, known as “prokaryotes”, comprise 30% of life in the world’s oceans. These organisms play an important role in keeping the oceans in balance. But new research by myself and colleagues shows this balance is at risk. We found prokaryotes … Read more
