Biology papers be like "The nucleus is part of the cell and contains a lot of DNA. Polycomb Repressive Complex 2 (PRC2)-mediated deposition of H3K27me3 establishes domains of facultative heterochromatin, silencing gene expression in a developmentally regulated manner."

There have been thousands of generations of humans, and you are alive to witness the first photo of a Sunset on another World. This is a real photo of the sunset on Mars.

Top 5 advances in medicine this week (🧵) 1. Gene therapy provided sight to children born blind The 4 children had a rare form of blindness, caused by mutations in the retina gene, AIPL1 A functional copy of this gene was introduced, in one eye per patient, using the other eye

In 20 years, NIH leadership and universities have done literally nothing to address this issue. If you just try to recreate experiments. You can only do it 10 -40% of the time. No one stood up for reproducible science

The hardest part about recovering from many months in space isn't the physical part (that is relatively easy). It is the administrative and paperwork things! getting my bills paid, safety inspection on car (I got a ticket), lawn cleaned up etc.

The whole “dire wolf resurrected” thing is super misleading. It’s an edited gray wolf genome (20 edits at 14 loci) based on variants associated with dire wolf phenotypes.

In a medical milestone, a customized base editor was developed, characterized in human and mouse cells, tested in mice, studied for safety in non-human primates, cleared by U.S. FDA for clinical trial use, manufactured as a complex with an LNP, and dosed into a baby with a severe,

Huh. Looks like Plato was right. A new paper shows all language models converge on the same "universal geometry" of meaning. Researchers can translate between ANY model's embeddings without seeing the original text. Implications for philosophy and vector databases alike.

Spanish oncologist Mariano Barbacid's team achieved complete elimination of KRAS-mutated pancreatic tumors in mice using a low-toxicity trio of drugs (gemcitabine, ATRA, and neratinib), as detailed in a January 27, 2026, PNAS study.

We worked with Ginkgo Bioworks to connect GPT-5 to an autonomous lab, so it could propose experiments, run them at scale, learn from the results, and decide what to try next. That closed loop brought protein production cost down by 40%.
