Researchers genetically engineer Salmonella to eat brain tumors

by Andrew Tarantola, Engadget

This is the first time you’ll actually want a case of food poisoning

Salmonella has earned its bad reputation. It is responsible for more than a million cases of food poisoning every year, of which nearly 400 people die. But a team of researchers from Duke University have recently engineered the bacteria to not attack the human gastrointestinal tract, but rather the most aggressive form of brain cancer known to man.

Neural Stem Cells Serve as RNA Highways Too

by Duke University, Neuroscience News

Scientists visualize potential mechanisms driving formation of new neurons in the brain

Duke University scientists have caught the first glimpse of molecules shuttling along a sort of highway running the length of neural stem cells, which are crucial to the development of new neurons.

This new view has given them an intriguing clue that a protein deficient in Fragile X syndrome, an autism-related disorder that causes intellectual disability, is responsible for moving at least some of this molecular cargo up and down the stem cells. The findings appear online Dec. 1 in Current Biology. Continue reading Neural Stem Cells Serve as RNA Highways Too
