Tranexamic acid modestly reduces bleeding after cesarean delivery in women

Giving tranexamic acid to women with placenta praevia (when the placenta covers the cervical opening) undergoing cesarean birth leads to a significant yet modest reduction in severe bleeding after delivery with no evidence of an increase in serious adverse events, finds a trial from China published by The BMJ today.

Brain-controlled hearing aid concept helps solve the cocktail party problem

Researchers developed a real-time brain-controlled hearing system that uses neural signals to identify and amplify the speaker a listener is focusing on in noisy, multi-talker environments. Using intracranial brain recordings, the system improved speech intelligibility, reduced listening effort, tracked attention shifts, and provided a benchmark for future brain-guided hearing aids.
