Leading AI models struggle to identify genetic conditions from patient-written descriptions

Researchers found large language models are more accurate with concise, textbook-like medical questions than patient-written summaries. The models achieved higher accuracy when using standardized language, but struggled with variable phrasing and format of patient write-ups.

Climate model biases in global monsoon: Insights from interhemispheric energy transport

A new study reveals that climate models exhibit pronounced biases in simulating the global monsoon, with the dry and wet biases found in earlier models persisting. However, CMIP6 models show significant improvements over CMIP5, attributed to reduced dry biases and better representation of energy transport.

New research identifies early sensorimotor markers for autism spectrum disorder

A study published in iScience has uncovered significant findings related to the early sensorimotor features and cognitive abilities of toddlers who are later diagnosed with Autism Spectrum Disorder (ASD). The research suggests that a higher IQ may confer resilience to atypical sensorimotor functioning, highlighting the need for more pr...
