Disease Detection Gets Boost from Keck’s New Brain Reference Map
A research team used diffusion magnetic resonance imaging (MRI) scans from more than 54,000 people to chart how the brain’s communication pathways develop, mature, and decline across the lifespan. The post Disease Detection Gets Boost from Keck’s New Brain Reference Map appeared first on GEN - Genetic Engineering and Biotechnology News.

Scientists stunned as bacteria rewire DNA machinery to shape cells
Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once used to separate DNA has been repurposed into something entirely different: a structure that shapes the cell itself.

Boosting the blood-brain barrier could avert brain damage in athletes
The neurodegenerative condition chronic traumatic encephalopathy appears to be driven by damage to the blood-brain barrier due to repetitive head injuries, like those that occur in boxing. This suggests that drugs that strengthen this barrier could prevent or slow the condition
