If you don’t exercise, just do 3x1 minute bursts of intense movement daily (rush up the stairs, walk briskly, bike hard, etc) In a UK Biobank study, this was associated with a 40% reduction in mortality

Scientists boosted a single protein in aging mice and the results were wild. Stronger muscles. Denser bones. Sharper cognition. All linked to Klotho, often called the “longevity protein.” It is only mice, and humans are more complex. But if Klotho proves out in people, we may…

Beautiful paper. Scientists solved the structure of myosin—the protein that forms contractile filaments in muscle cells—in multiple configurations using Cryo-EM. They captured the entire power stroke action (where myosin pulls on actin to shorten the muscle) at4.4 Å resolution.

AI can't "solve" all diseases for the simple reason that all diseases were solved by computational chemistry in 1985, by high throughput screening in 1995, by genomics in 2000, by RNAi in 2004, by stem cells and nanotechnology in 2005, before being solved by CRISPR in 2015.…

Extremely clever new NGS tech from Roche 🧬 If it's hard to discriminate between nucleic acids accurately with a nanopore, why not synthesize a new polymer off a DNA template that is easier to sequence? It's an intuitively simple idea, but took *a ton* of creative nucleic acid…

Crystal structures are *not* God-given truth. They approximate, w/ flaws & errors, X-ray diffraction data. AlphaFold etc. have been trained on structures, not data. SFCalculator now differentiably connects structures to diffraction data. What does this enable? 🧵 1/4

Beyond troubling racial implications @MIT @NeurIPSConf, the quote do NOT represent Chinese education or culture, which emphasize morality, virtue and doing the right thing. rely on hearsay and broadly paint Chinese or Chinese students in a negative category is simply unacceptable

1/3 Today, an anecdote shared by an invited speaker at #NeurIPS2024 left many Chinese scholars, myself included, feeling uncomfortable. As a community, I believe we should take a moment to reflect on why such remarks in public discourse can be offensive and harmful.

Most MIT profs who I know are extremely honest and morally upright. I hope this is an exception.

It's like when a journalist asks Ted Bundy why he's a serial killer, and he says it's because American society didn't teach him morals and values, so the journalist concludes that American society won't teach morals and values.
