A mutation on the spike protein of the virus that causes COVID-19 could help it infect the brain by forcing it to use a cellular "back door."

ChatGPT's medical diagnoses are accurate less than half of the time, a new study reveals.

Scientists asked the artificial intelligence (AI) chatbot to assess 150 case studies from the medical website Medscape and found that GPT 3.5 (which powered ChatGPT when it launched in 2022) only gave a correct diagnosis 49% of the time.

"Examinations commonly use either free-response (FR) or multiple-choice (MC) response formats, each with its advantages and disantvantages.

"aimed to investigate how test takers´ characteristics and behavior - particularly test anxiety, risk propensity, conscientiousness, lecture attendance, and study time - impact test scores in exams with FR and MC format."
