Google AI Releases DeepPolisher: A New Deep Learning Tool that Improves the Accuracy of Genome Assemblies by Precisely Correcting Base-Level Errors
Google AI, in collaboration with the UC Santa Cruz Genomics Institute, has introduced DeepPolisher, a cutting-edge deep learning tool designed to substantially improve the accuracy of genome assemblies by correcting base-level errors. Its notable efficacy was recently demonstrated in advancing the Human Pangenome Reference, a major milestone in genomics research. The Challenge of Accurate Genome Assembly A reference genome is an essential foundation for understanding genetic diversity, heredity, disease mechanisms, and evolutionary biology.

An NIH training grant paid for my PhD. An NSF grant paid for my postdoc. More than 90% of the funding to my lab over last 16 years has been from NSF. A bleak outlook for young researchers.
2002. A cybercafe in Times Square, NYC. I apply for an NSF grad fellowship while teaching 10th grade biology and renting a single room in a brownstone with no Internet. I get it, letting me study & research frog immunity without having to support myself as a teaching assistant. #WithoutNSF [thread]

I just met with a researcher whose USDA grant was terminated. Does he study a DEI related topic? Climate change? Nope. His research is on reducing the spread of E. coli in poultry.

Do you (like me) create a bunch of conda environments, then later forget what they're for, when they were last updated, or which tools are in them?

If so, you might this little project: github.com/rrwick/conda...

Is this real, or is it excessive AI hype? New paper claims that an AI foundation model "achieves experimental-level accuracy in predicting gene expression even in previously unseen cell types." I'm reading the paper now, but I don't believe it for a second:
