Novel neural net recognizes spoken words better than human listeners

Researchers at USC created a machine system that recognizes spoken words better than humans, with the ability to distinguish words in vast amounts of random noise. The novel neural network architecture mimics the biological system's temporal dimension, allowing it to process information structured in time.

Treatments reduce strep-triggered symptoms of OCD and tics in some children

Researchers found that plasma exchange and IVIG relieve neuropsychiatric symptoms in children with tics and obsessive-compulsive disorder, with symptom improvements lasting up to a year. The study suggests these treatments may be effective for a subgroup of children with strep-triggered disorders, but not all cases.

Study: foreign-trained physicians vital to poor, under-served patients

A new study found that nearly a quarter of community health centers rely on foreign-trained physicians, who are often willing to accept lower salaries. If these doctors were no longer available, up to 57% of positions for foreign-trained doctors and almost 16% of all staff positions could go unfilled.
