Let’s take a closer look at this protein structure determined using AlphaFold2. This protein structure is part of a huge molecular structure in the human body. More than a thousand proteins form a pore through the membrane surrounding the cell nucleus. Animation: ©Terezia Kovalova/The Royal Swedish Academy of Sciences #NobelPrize

This is a bacterial flagellar motor … one of nature’s most sophisticated molecular machines - a rotary motor embedded in the cell membrane consisting of ~25-30 protein types totaling 20,000-50,000 atoms in a multi-part structure of rotor, stator, drive shaft, and propeller. Operating at 100-300 Hz (6,000-18,000 RPM) with some species reaching 1,700 Hz (~100,000 RPM) at nearly 100% efficiency, this nanoscale engine features rotor proteins FliG/FliM/FliN forming the C-ring, MotA/MotB stator complexes, FlgG rod protein drive shaft, FliC flagellin propeller filament, and FlgE hook proteins acting as a universal joint, all powered by proton or sodium flow across the membrane generating torque through conformational changes in the stator complexes.

🚨 BREAKING: Particles don’t “choose” a path. They follow structure. In the double-slit experiment, matter behaves like a wave… until measured. But what if nothing is “collapsing” at all? What if: reality is a structure observation changes the structure and particles just follow the new path Not randomness. Not magic. Just systems rebalancing. So maybe the question isn’t: “Why does the wave collapse?” It’s: What changed the structure? Follow this changes everything.

🟢The crystal structure of the green fluorescent protein, GFP! 🟢 The chromophore is yellow. The protein rigidizes the chromophore to release energy as fluorescence. 🎥I made the movie with UCSF Chimera & 1EMA.pdb. #FluorescenceFriday #FluorescentProtein #GFP #SciComm

I wrote this fun interactive article explaining Isomap, a classic non-linear dimensionality reduction technique. Isomap captures the local similarity structure of data through a graph and computes an embedding that preserves this structure. Check it out! Link below.

🌌🛣️ James Webb Found a Cosmic Highway. Using the James Webb Space Telescope, scientists have observed a huge structure — a chain of around 20 galaxies stretching millions of light-years across the early universe. This structure is likely part of the cosmic web, where dark matter guides the formation of galaxies along filaments. The light from these galaxies has traveled for over 13 billion years, revealing how the universe began organizing itself into large-scale patterns. This discovery gives us a glimpse of the universe’s early “skeleton” — the framework that shaped everything we see today.

🚨 Scientists may have found a hidden shortcut to Mars using asteroid orbits. A new study suggests asteroid orbital geometry could cut Mars round trips to 153 days shaving hundreds of days off conventional missions. The idea: Use the geometry of small-body orbital planes like gravitational “corridors” through the Solar System. Not brute force. Structure. Navigation through celestial resonance. Sometimes progress isn’t pushing harder through space it’s discovering the path space already allows. Mars may be closer than we thought. Follow me I track where physics becomes structure.

Check out my new work with Frank Noe where we answer if the structure of different protein conformations really can be predicted. Also try the Colab to see if your protein has different conformations:

Check out the structure of this supercell in a conditionally volatile environment for tornadic storms but in a tipping point state. A few degrees warmer at the surface, a tickle more surface convergence, or lift and would have had big problems
