PyTorch Hub is an awesome new step forward in research reproducibility for machine learning and artificial intelligence. Makes it super easy to publish your pre-trained research models and for others to download them and test them. I was shocked how uncommon it was for people to publish their models when I first started reading machine learning papers.
This was a metagenomic study that identified two enzymes that may help convert A and B blood to O increasing the supply of blood available.
This is a cool ArXiv access point with upvoting and down voting, ability to save notes, see twitter commentary on paper and more.
