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.

Kyren Paris has hit .157 with 7 HR’s in his first 217 big league at bats…. Albert Pujols hit .354 with 20 HR’s in his first 217 big league at bats… Kyren Paris hits with the muscles of motor tract 5 on his right side… Albert Pujols hit with the muscles of motor tract 1 on his right side…. MT1 uses the pec major to internally rotate the humerus towards contact… MT1 uses 5 uses the latissimus dorsi to medially rotate the humerus towards contact… Watch their rear shoulder/chest area at front foot heel strike and you will see just how different they are moving.

Scientists are baffled by this. The Bacterial Flagellum is composed of 20-30 unique parts. Combined, they total over 30,000 parts that make this little motor run. It can hit rotation speeds of up to 100,000 RPM, then stop & reverse direction in a quarter of a turn. It can propel a bacteria up to 20 lengths per second, which when scaled up is about equal to 225mph in a car. But this motor only works when all those parts are perfectly engineered and working together. Take away just one of those 30 pieces, and it stops functioning. That means it can't evolve gradually. None of the pieces do anything outside the system, and the system only works with all the pieces. Bacteria require this motor to move - without it, they would quickly die. How can anyone see something like and still deny that Life is Divinely Designed?

Skin color is the least significant biological difference between the races. The far more significant differentiator is PSYCHOLOGICAL. Different races have dramatically different hardware in their brains, which leads to different types of cultures and societies being built by those people. For this reason among many others, #Multiculturalism will never work. It will ALWAYS end in conflict, as different racial tribes with different genetic wiring will always want different things, and prefer different social structures that support their cultural desires. #Nationalism is about giving all of these different groups their own sovereign nations where they can live peacefully amongst their own kind, and pursue their tribal destiny together without the constant stress of needing to fight clashing values or demographic dilution from foreign outsiders. It's the clear best path forward for all parties involved.

System identification (sysid) is the process of finding the physical parameters that make a simulation match reality. If you're training an RL locomotion policy in simulation, the accuracy of your motor model directly affects how well the policy transfers to the real robot. A recent git commit by Kevin Zakka added a sysid toolbox to MuJoCo which automates this process: you provide recorded motor data and a MuJoCo model, and it optimizes the model parameters to minimize the difference between simulated and real trajectories. For my RobStride Dynamics RS02 QDD motors (17 Nm peak, 7.75:1 gear), I built a Rust tool that sends multi-sine torque excitation at 1 kHz and records position/velocity feedback. I then feed this data into MuJoCo's sysid optimizer.

In Eldoret, Kenya, a disturbing incident captures the harsh reality of African mistreatment at the hands of foreign exploiters. Inside a blacksmith shop owned by a Chinese businessman, a Kenyan worker is violently attacked and publicly humiliated by his Chinese employer as he flees without resistance. The scene starkly highlights how Africans are being degraded on their own soil—stripped of dignity, silenced by fear, and subjected to abuse by those who see them as lesser in their own homeland.

Done for the day, back again tomorrow 9AM for more videos. Woody: "I don't get my sleep Judge, can I come back at 10 or 11?" (By the way, Young Thug is regularly forced to wake up before 6 AM for transport since he's jailed in a different county 😐)

🇺🇸🇮🇷‼️ US TO START BOMING IRAN AGAIN! There is no way there is a permanent peace deal by end of June … emphasis on PERMANENT peace deal. Maybe a ceafire which will be broken soon again. The odds at 31% are too high in my opinion!

This is one of the most viral videos I’ve ever seen, with 7.4 million Likes The reason it’s so viral is because people think this cookie is haunted It breaks off camera, then in the middle of explaining what happened it mysteriously breaks again. The girl screams in fear Here’s what’s actually happening, This is Dalgona candy. It’s breaking on its own because of its brittle structure and internal stress, not anything supernatural Dalgona is made by mixing sugar with baking soda, creating a honeycomb texture. It’s extremely prone to cracking. During cooling, different parts of the candy shrink at slightly different rates. This builds up stress, which eventually releases by causing a crack We need a better education system

For your baby, play and learning are one and the same. And here’s a great example. This little one, shared to IG by aylinkababy, is exploring cause and effect. As she opens and closes her hand, she flicks the heart shaped bead - causing it to spin on its axis. It’s not just a lesson on how the toy itself works, but a lesson in agency. She’s learning how her own actions can make things happen in the world. (It’s also providing a fantastic opportunity to develop her fine motor skills, as she’s required to strike her fingers against the toy in just the right place to achieve her desired spinning result.) Developmentally, children typically begin exploring cause and effect at around 4 months. And cause and effect toys are a great option, beginning around this age. While this video highlights the spinning bead at its center, note that this toy offers several such opportunities. Shaken it will make a rattling sound. And because of its clear plastic tubing, the balls inside will roll in the direction the toy is shifted. All great opportunities for baby to explore the effects of her actions.

Your baby is a natural born dancer. (And so are you.) Music simultaneously activates multiple regions of the brain, not least of which the motor cortex which guides rhythm and movement. This is especially true of uptempo music, which matches or exceeds your baby’s heart rate. Here you’re likely to see your baby react, from even the earliest stages of development. Check out this little guy, shared to IG by ernhanatha24, who’s moved to dance in response to a song improvised by his mom. We can’t see her off screen, but my bet is that she is modeling some of these very same dance moves as she sings. Either way, little man’s got the beat!

I’ll be right there… I’m new at this! One of the most amazing things about being a parent is that there are new and special moments at every stage of development (right into adolescence and adulthood). But what a special time it is when babies emerge into toddlerhood - developing motor and language skills all at once. This little one, shared to IG by jamesandersonw10, is hitting these developmental milestones right and left, taking some of her first tentative steps while using language (which sounds very much like “coming!” - but could well be an effort to mimic dad’s “come on”), to cheer herself on. Talk about putting it all together! 🧩

This is Shahed drone but not the same ‘world famous’ Delta wing Shahed. This is Shahed-101, a loitering munition drone that attacked the fuel storage site in Erbil. Shahed-101 struck a Castrol linked warehouse at Sardar Group facility. How is ‘101’ different from ‘136’? Shahed-101, a 26 KG drone uses electric motor, so it does not make noise like ‘136’ or Arash drones. It can go upto 1500 km with 8 KG warhead. On the other hand, a 200 KG Shahed-136 uses a piston engine and it can go upto 2500 km with 50 KG warhead. So Shahed-101 is a new weapon in this war with low cost saturation tactics against million dollar interceptors. They can hit Israel.

It's been incredible to see neural networks working so well on our humanoid robots Humanoids are crazy complex - an individual motor can rotate 360 degrees and you have 40+ joints. If you do the math, that means more possible robot states than atoms in the universe Figure has our own AI model called Helix that we've designed in-house. A single Helix neural network now outputs both manipulation and navigation, end-to-end from language and pixel input Every leap in machine learning has come from massive, diverse datasets. At Figure, we’re currently building the largest pretraining dataset for humanoids in history - excited to see what this unlocks

⚠️🚨 𝗔𝗧𝗧𝗘𝗡𝗧𝗜𝗢𝗡 𝗣𝗥𝗢 𝗪𝗥𝗘𝗦𝗧𝗟𝗜𝗡𝗚 𝗙𝗔𝗡𝗦🚨⚠️ If you're at a show and wrestlers start breaking fluorescent light tubes in the ring, GET OUT IMMEDIATELY. These tubes release toxic mercury vapor posing serious health risks; especially in enclosed spaces like gyms. Mercury is a neurotoxin, meaning it can have damaging effects on the brain and nervous system. Here’s how mercury exposure, especially from inhaling mercury vapor, can impact the brain: 1. Cognitive Decline: Mercury can damage neurons and impair brain function, leading to memory loss, concentration issues, and a decline in overall cognitive abilities. 2. Mood and Behavioral Changes: Chronic mercury exposure is linked to mood swings, irritability, anxiety, and depression. Historically, the phrase "mad as a hatter" came from hat-makers who experienced mercury poisoning from chemicals used in hat production. 3. Motor Coordination Problems: Mercury exposure can damage areas of the brain responsible for motor control, leading to tremors, muscle weakness, and coordination issues. 4. Developmental Risks: In children and developing fetuses, mercury can severely impact brain development, leading to learning disabilities, lower IQ, and problems with motor skills, attention, and language. 5. Sensory Impairments: High levels of mercury exposure may lead to impaired vision, hearing, and speech. Mercury's effects on the brain are particularly severe because it can accumulate over time and cross the blood-brain barrier, meaning even small exposures can lead to long-term damage with repeated exposure. PS: Now we know why the leftist IWC are so freaking stupid.
