@EricTopolWatermarking AI-generated proteins, with preservation of their function, to establish provenance. A needed innovation. In today's @Nature by @pushmeet and colleagues @GoogleDeepMind https://www.nature.com/articles/s41586-026-10965-y https://www.nature.com/articles/d41586-026-03033-y
@demishassabisBiosecurity is one of the most urgent challenges for the AI era. Bringing SynthID to biology so AI-generated proteins can be watermarked is a critical step - and we’re open sourcing SynthID Bio tools so the research community can build on this work. Published in @Nature today, congrats to the team! https://www.nature.com/articles/s41586-026-10965-y
@NewsfromScienceDesigning novel proteins isn’t the slog it used to be. The rise of AI in biomedicine has made it substantially easier to create original sequences of amino acids that fold into functional proteins—prompting fears bad actors could exploit the technology to make new toxins or other harmful agents. Now, scientists with @GoogleDeepMind propose a partial solution. They describe a way to denote a protein’s AI origin by subtly altering the probability of amino acids chosen for its sequence. The resulting pattern acts as a statistically detectable stamp, or watermark, while preserving the protein’s structure and function. Learn more: https://scim.ag/4rItBj9
@_mordn_DeepMind quietly shipped something more interesting than today's frontier model: SynthID Bio. Watermarks AI-designed proteins in the structure itself — the signature survives synthesis, so a physical protein traces back to the model that designed it. https://deepmind.google/blog/introducing-synthid-bio/
@SkyeSharkie"I'm sorry, you appear to have SynthID watermarked protein levels of above 50%, that means you don't qualify for our human rights package!"
