Study: Low Carb Diet May Prevent, Reverse Age-Related Effects Within the Brain
The news in brief: 1) Brain changes associated with aging become visible much earlier than would be expected, in the late 40's. 2) This is hypothesized to result from neurons’ loss of energy; if so, researchers may have found a way to prevent or reverse these effects. 3) This can be done with diet, by

Six works of Computer Science-Fiction (2015)
Computer Science-Fiction 1 is not actually fiction. Instead, these are books of computer science and/or programming that when you read them you can’t quite believe that what they claim is reality. Indeed, very often works of Computer Science-Fiction push the limits of your understanding of just what constitutes the…

It took two days to develop Moderna’s vaccine
As the first crop of SARS-CoV-2 vaccines are being rolled out, we can start to see the light at the end of this pandemic tunnel. Still, in the US alone there will probably be another 200,000 deaths before we reach herd immunity. Further, as fast as this vaccine development and deployment was, it's not clear
