WRITER FUEL: New Algorithm Could Help AI Read Thoughts in People With Aphasia

brain network - deposit photos

Scientists have made new improvements to a “brain decoder” that uses artificial intelligence (AI) to convert thoughts into text. Their new converter algorithm can quickly train an existing decoder on another person’s brain, the team reported in a new study. The findings could one day support people with aphasia, a brain disorder that affects a … Read more

Writer Fuel: NASA Rover Discovers Liquid Water ‘Ripples’ Carved Into Mars Rock

Mars water ripples - NASA

Scientists have discovered evidence that liquid water was once exposed to the air in ancient, shallow lakes on Mars. The finding is evidence that not all water on the Red Planet was covered in ice, as some Martian climate models suggest. Planetary geologists and astronomers studying Mars have known for decades that water was once … Read more

Writer Fuel: Some Older Generative AI Models Show Signs of Cognitive Decline

AI / Artificial Intelligence - deposit photos

People increasingly rely on artificial intelligence (AI) for medical diagnoses because of how quickly and efficiently these tools can spot anomalies and warning signs in medical histories, X-rays and other datasets before they become obvious to the naked eye. But a new study published Dec. 20, 2024 in the BMJ raises concerns that AI technologies … Read more
