A paper in Nature Medicine presents a device platform that converses with patients to help them manage their epilepsy. In a small test, patient feedback helped the system improve seizure detection, cutting false alarms by about 80 percent. go.nature.com/489Oo5X #medsky 🧪

How does the brain represent symbolic integers and fractions? This study shows that educated adults process both integers and fractions within a shared, topographic map, indicating that the brain integrates numerical concepts to compare magnitudes. 🧪 #NeuroSky #math #numerosity plos.io/4jveiIp

"I spent the months of March, April, May & June last at No. 4161, Riva dei Schiavoni, where I had a little fourth floor, the view so divine (...) & the situation so convenient, that it was a very tolerable situation. I wrote there the larger part of my last novel." - Henry James

Indeed they did. This is an important change that will make biomedical science like cancer and dementia research worse, by allowing newly political roles (program officials now under Schedule F/P/C and IC directors chosen by politicals) free rein to choose projects to fund.
