“The first news summary of the morning —the most comprehensive I’ll receive all day— and the last thing I read before going on air.” — Hugh Hewitt, host of The Hugh Hewitt Show.

Thanksgiving Holiday Schedule: (1) News Items WILL be distributed tomorrow (Wednesday, 27 November). (2) News Items WILL NOT be distributed on Thursday (11/28) through Sunday (12/1). (3) It will resume distribution on Monday, 2 December. We will distribute a Thanksgiving Prayer on Thursday morning.

Happy Thanksgiving to one and all and thank you for your support. We’re a going concern because of it.

1. Abstract:

With a vocabulary of just four nucleotides, the language of DNA encodes the fundamental information needed to orchestrate all layers of regulation in a cell, from DNA to RNA and proteins. These instructions direct the function of each cell and transmit information between generations. Changes in the genomic sequence drive evolution, enabling organisms to adapt to their environments through natural selection of advantageous DNA sequences. Therefore, comparing DNA sequences across evolutionarily diverse genomes could enable a large language model to learn the grammar of DNA, which has eluded models trained on single genomes (1). On page 746 of this issue, (Eric) Nguyen et al. (2) present Evo, a foundation model trained on 2.7 million evolutionarily diverse prokaryotic and phage genomes. Having learned genomic logic, Evo can decode natural genomes; enable predictions and design tasks across DNA, RNA, and proteins; and generate DNA at the whole-genome scale.
