Graph Networks for Materials Exploration
We share the discovery of 2.2 million new crystals – equivalent to nearly 800 years’ worth of knowledge. We introduce Graph Networks for Materials Exploration (GNoME), our new deep learning tool that dramatically increases the speed and efficiency of discovery by predicting the stability of new materials.

AI system self-organises to develop features of brains of complex organisms
Cambridge scientists have shown that placing physical constraints on an artificially-intelligent system – in much the same way that the human brain has to develop and operate within physical and biological constraints – allows it to develop features of the brains of complex organisms in order to solve tasks.

Nanoplastics promote conditions for Parkinson's across various lab models
DURHAM, N.C. – Nanoplastics interact with a particular protein that is naturally found in the brain, creating changes linked to Parkinson’s disease and some types of dementia. In a Duke-led study appearing Nov. 17 in Science Advances, the researchers report that the findings create a foundation for a new area of…

Open, rigorous and reproducible research: A practitioner’s handbook (2021)
Even though many scientists are expected to abide by the principles of open, rigorous and reproducible research, few scientists actually receive formal training in this. Indeed, there is no collection written by working scientists for working scientists about the principles of transparent, rigorous and reproducible…
