More than 100 hours of MIR scanning has generated an image of a whole human brain with unprecedented level of detail. Massachusetts General Hospital researchers and their colleagues used a 7 Tesla MRI machine, recently approved by the FDA, to scan the donated brain from a 58-year-old-woman. The image shows detail down to .1 millimeter. From Science News:
Before the scan began, researchers built a custom spheroid case of urethane that held the brain still and allowed interfering air bubbles to escape. Sturdily encased, the brain then went into a powerful MRI machine called a 7 Tesla, or 7T, and stayed there for almost five days of scanning...
Researchers can’t get the same kind of resolution on brains of living people. For starters, people couldn’t tolerate a 100-hour scan. And even tiny movements, such as those that come from breathing and blood flow, would blur the images...
These (new kinds of) detailed brain images could hold clues for researchers trying to pinpoint hard-to-see brain abnormalities involved in disorders such as comas and psychiatric conditions such as depression.

There’s been an explosion and fire at the Russian State Centre for Research on Virology and Biotechnology (Vector), a facility near Novosibirsk in Siberia that happens to hold live samples of smallpox. Vector officials say there’s currently no risk of contamination. Vector and the US Centers for Disease Control and Prevention are the only two […]
Ebola is now a treatable disease.
Between 2010 and 2016, the FDA approved 210 new medicines and every single one was produced at public expense, part of a $1T US government investment project in medical research. Despite this massive public subsidy, the pharma industry has only grown more concentrated and rapacious, raising prices and diverting the profits to their execs and […]
