Virtual Brain Models Brain Tumor Progression, Effects of Surgery

Structural brain network in a brain tumor patient from the study. Different brain regions are depicted as spheres, whose size indicates the relative importance within the network. The strength and direction of the structural links between them is represented by different colors and width. The brain tumor, a large meningioma, is the orange mass.

Seeing Stress With Supercomputers


It's easy to take a lot for granted. Scientists do this when they study stress, the force per unit area on an object. Scientists handle stress mathematically by assuming it to have symmetry, but new supercomputer simulations show that at the atomic level, material stress doesn't behave symmetrically. The findings could help scientists design new materials such as glass or metal that doesn't ice up.


DeepMind's New AI Teaches Itself Chess, Beats Grandmaster


In late 2017 DeepMind introduced AlphaZero, a single system that taught itself from scratch how to master the games of chess, shogi (Japanese chess), and Go, beating a world-champion program in each case. Today, they announce the evalutation of AlphaZero, published in the journal Science, that confirms and updates those preliminary results.


Oligodendrocytes, Microglia and Astrocytes Linked to 'Chemo Brain'


Three types of cells in the brain’s white matter show interwoven problems during the cognitive dysfunction that follows treatment with the cancer drug methotrexate, Stanford neuroscientists have found.
