Swings and misses with Jeremy Veenstra-VanderWeele
A careful clinician who prizes evidence, Jeremy Veenstra-VanderWeele is happy to embrace trial failures, as long as he learns from them.
Ruth Carper: Imaging the aging brain in autistic adults
Few studies have tracked how brain structure and function change across adulthood in people with autism. Carper and her colleagues are collecting data to fill this gap.

Modern AI is simply no match for the complexity likely required for harboring consciousness, says Jaan Aru
He argues that our brain’s computations are of a completely different nature than any artificial intelligence because they take place across many spatial and temporal scales and are inextricably entwined with biological materials.
