Emerging protein-design competitions aim to sift out the functional from the fantastical. But researchers hope that the real prize will be a revolution for the field. Illustration: Ibrahim Arafath On a Saturday morning in mid-August, Alex Naka embarked on what he describes as “a little hackathon” in his girlfriend’s kitchen. Powered by his laptop, some...

AI scans RNA ‘dark matter’ and uncovers 70,000 new viruses
Newly-discovered viruses live in hydrothermal vents and other extreme environments. Credit: Alexis Rosenfeld/Getty Researchers have used artificial intelligence (AI) to uncover 70,500 viruses previously unknown to science1, many of them weird and nothing like known species. The RNA viruses were identified using metagenomics, in which scientists sample all the genomes present in the environment without having...

Using a generative AI assistant to interpret pharmacogenetic test results
by Molly Chiu, Baylor College of Medicine Credit: Pixabay/CC0 Public DomainGenetic test results can be hard to understand and interpret for people without a background in genetics. Investigators at Baylor College of Medicine’s Human Genome Sequencing Center are studying whether an artificial intelligence (AI) assistant could be beneficial in answering questions about these results for...

AI Model Can Help Determine Where a Patient’s Cancer Arose
Predictions from the OncoNPC model could enable doctors to choose targeted treatments for difficult-to-treat tumors. For a small percentage of cancer patients, doctors are unable to determine where their cancer originated. This makes it much more difficult to choose a treatment for those patients, because many cancer drugs are typically developed for specific cancer types. A...
