LEONARDO, also called LEO, was built by researchers at Caltech’s Center for Autonomous Systems and Technologies. Its full name means LEgs ONboARD drOne. The idea is simple but unusual: • Build a small biped robot • Give it drone-style thrust • Use the legs for ground contact • Use the propellers for balance and lift • Combine walking, hopping and flying in one system LEO is basically a hybrid between a walking robot and a flying drone. How it was built: • Two lightweight legs • Three actuated joints in each leg • Four propeller thrusters near the shoulders • A lightweight body • Leg motors for ground movement • Propellers for balance, lift and aerial control • Real-time control software that synchronizes the legs and propellers How it walks: • The legs move the robot forward • The feet touch the ground like a normal biped • The propellers constantly correct balance from above • The robot can stay upright even in unstable situations • The thrust reduces the risk of falling during difficult motions How it flies: • The legs stop being the main locomotion system • The four propellers generate lift • The robot behaves more like a drone • It can take off, fly over obstacles and land back on its legs What makes it different: • It does not walk like a normal humanoid • It does not fly like a normal drone • It blends both systems • The legs handle contact with the ground • The propellers act like fast stabilizers • The control system decides how much help comes from the legs and how much comes from thrust That is why LEO can: • Walk • Hop • Fly over obstacles • Ride a skateboard • Balance on a slackline The key idea is walking with aerial stabilization.

I created a dance movement sheet by using a reference image to animate every 16 panels from the reference image I provided. GPT Image 2 + See Dance 2.0 on Yapper Tutorial Below Prompt Here’s every step with the text under each heading: 1. Basic Stance Stand with your feet shoulder-width apart. Relax your knees. Keep your upper body relaxed. Get ready. 2. Step to the Right Step to the right. Move your body in the direction of the step. Keep your knees soft. Keep your gaze forward. 3. Step to the Left Step to the left. Move your body in the direction of the step. Keep your knees soft. Return to the starting position. 4. Two Steps Take two steps in sequence. Step to the right first. Then step to the left. Connect smoothly. 5. Body Wave Start the wave from your chest. Move through your ribs and hips. Finish with your lower body. Make the motion smooth like a wave. 6. Hip Sway Move your hips side to side. Shift your weight with the motion. Use your body naturally. Keep your upper body relaxed. 7. Arm Swing Swing your arms wide. Step to beat with your feet. Coordinate your arms and steps. Return your arms to center. 8. Turn Preparation Prepare for a turn in place. Cross one foot over the other. Use your core to maintain balance. Spot in the direction of the turn. 9. Right Turn Turn to the right. Keep your core engaged. Pivot on the ball of your foot. Spot forward after the turn. 10. Left Turn Turn to the left. Keep your core engaged. Pivot quickly. Keep your posture upright. 11. Jump Up Bend your knees and jump up. Reach your arms overhead. Land softly on your feet. Connect to the next move. 12. Kick Pose Kick your leg forward. Keep your supporting leg stable. Engage your core for balance. Control your landing. 13. Side Lunge Step wide to one side. Bend one knee and lower your body. Keep the other leg straight. Show the direction of your strength. 14. Freeze Pose Hit a strong pose on the beat. Freeze your body momentarily. Create a powerful shape. Show your presence. 15. Finishing Pose Finish the dance gracefully. Keep your balance. Show your confidence. End with a clean, sharp pose. 16. Whole Flow Connect from the basic stance to the finishing pose. The steps, waves, and turns flow naturally together. Express your own style.

👀Connecting your coaching eye to your clinical reasoning! Observe the leg cycle of the leg closest to the camera on each drill. Can you see small medium then big elliptical on the right limb and very limited ones on the left? What does limb movement and synergies say about muscle properties and pelvic structure ? Does “technique” matter? Well only if you want to load specific tissues and create protective system tension. We had a really interesting 10.6 sprinter with repeated right side hamstring strains over the past year join our hamstring workshop. UPMC Sports Surgery Clinic 💪🏾Isokinetic tests have him really really strong on both limbs. 🔋Emg told a story of right side dominance and good lateral to medial hamstring balance whilst the left side was far more imbalanced with medial hamstrings dominating action that we assumed the lateral would. 🧐When we went on to the track, we saw similar things. 🚩Notably a reluctance to open up into late swing phase, avoiding long lever eccentric stress on the distal hamstrings…. ON THE LEFT LEG! Well this was noticed across a range of exercises velocities and complexities. 🏃🏾‍♀️ Drills with speed and locomotion, static fast drills as well as static slow drills. 🧐Movement illuminates structural qualities. 🧐Can you spot the difference in these two leg cycles? Could it be that the right side is repeatedly hurt due to the deficit in the left side. After all, if you can’t integrate late swing phase, then you will have poor negative foot speed. You will be able to accelerate…. But all the work will be on the right side the deeper you get into a sprint. Ed Mias Sportsmith

Is strength important for speed development? Here’s my take ⤵️⤵️ For context — this is me cleaning 295 lbs at 167 lbs body weight and I credit my abilities in the weight room largely for helping my collegiate career flourish the way it did However… We can’t lift at the expense of speed training and development What that means is when we enter the weight room we can’t do so with blinders on acting as if the only thing in the world that matters is that weight training session or improving your 1RM YES… you need force to move your body through space YES… that force needs to be high relative to your body weight BUT… you must be a skilled mover to apply said force in the right positions, at the right times, with the right vectors for it to mean anything While important to holistic athletic development, we’ve got to stop acting like strength is the ultimate differentiator in speed Lot of “weak” athletes will blow your doors off in sprints Lot of “strong” athletes get folded in speed & power sports Go into the weight room with the idea that you’re complementing your speed and athletic development… not superseding it If your legs are so beaten and broken down from lifting heavy you can’t train for 2-3 days without excessive risk, you’re doing it all wrong. Just some perspective from someone who once pursued 1RMs to no end while my track times stagnated… and then was enlightened by world class coaches who lifted within the context of my sport to take me from a college tryout to D1 All American What’re your thoughts? Let’s discuss in the comments!

sorry, they just did WHAT someone gave a machine one disease name, the leading cause of blindness in the developed world with 1.5 million americans already in its path, and it came back pointing at a drug that has sat in pharmacies for years under a different label: 551 papers read in 30 minutes against the 294 hours a human would have needed, and the loop that did it is public on GitHub most agent setups answer one question at a time, so the ceiling on the work is the quality of the question you happened to think of this one was handed a single question and wrote the second one itself. turns out that follow-up is where the real find was: a target called ABCA1, upregulated threefold, in an experiment no human ordered i read the whole paper looking for the trick, and the trick is structural. that is the second question, and it is the gap between an assistant and a factory: - hand the loop a field rather than a task: it was given a disease, and choosing the mechanism was part of its job - make it rank before it spends: 151 papers in, ten candidate mechanisms out, scored against each other before anything touched a bench - split reading from judging, so the agent that forms the theory is a different agent from the one grading it - close every cycle on physical reality: the verdict was an experiment, and another model's opinion was never allowed to stand in for one - feed each result back as the next question rather than a log line, which is the step almost nobody builds - search what already passed inspection first: the winner was an approved compound with a safety file already on record - write down what the round learned before opening the next one, so round two starts where round one stopped my read, and i think it is the uncomfortable one: reading was the entire bottleneck in that field, and everybody spent the decade optimising the writing. people ran every physical experiment here, the analysis agent needs a domain expert writing its prompts, and the authors decline to call this the leap it resembles. the thinking got replaced, and the hands did not so the question i cannot answer for my own setup: which step of your loop still stops dead until you sit down and type something bookmark this one. the four parts that turn one model into a line that runs like this, the queue, the rooms, the write permissions and the gate, are built file by file in the piece below ↓

AI has had exactly two scaling axes that worked so far, and the second one is starting to look finite too the first one was pretraining: with scaling parameters and data, we got world knowledge (i.e. ChatGPT had read enough to know things), but it started saturating a while ago the second one was RL, and people had been doing RL the whole time before that: RLHF is RL but it never scaled far because it was trying to control the exact output, which tokens come out, how the text reads, but you can only push that so far before you’re just polishing RLVR dropped that constraint: giving the model a task, then checking whether the final answer is right, and ignoring everything in between -- so the model does whatever it wants in the middle and only the endpoint gets graded, and that’s much closer to actual RL and it’s what bought us planning and reasoning (arguably, tool use sits around 2.5 on this list -- while useful, it's not a different kind of thing) so one axis gave knowledge, the other gave reasoning, and both of them are one model working alone the next axis is how many models you can get working on the same problem, which is a different kind of axis than the previous two we know that multi-agent RL has always been the harder problem: I spent years in that literature and the gap between single-agent and multi-agent is definitely not incremental -- it’s a whole different class of difficulty! which is also why the derivatives are steep at the start, nobody has picked the easy wins yet... and the thing that gates this multi-agent coordination is communication: models can only coordinate as well as they can exchange information, and right now they do that by writing sentences to each other imagine what could we possibly achieve if we properly open that third axis development by letting models to exchange information in their native "language" without loosing any computational data that they produce during inference

BEIJING JUST BECAME THE MOST DANGEROUS ROOM ON EARTH. HERE'S WHAT COMES NEXT, STEP BY STEP: Xi just hosted Trump. Then, before the ceremonial trappings were even cleared, Putin walked through the same door. That sequence is not coincidence. It's a message. Here's what comes next, step by step: 🔴 Step 1 — Xi positions China as the indispensable power Trump came first. Putin came second. Beijing received both. That's not diplomacy. That's leverage. Xi is telling Washington and Moscow simultaneously: you need me more than you need each other. 🔴 Step 2 — Putin and Xi sign 40+ documents on energy, trade, and security China is already Russia's largest oil and gas buyer — Europe's pipeline imports collapsed to their lowest levels since the mid-1970s after sanctions. These deals deepen that dependence and lock in the economic architecture of the anti-Western bloc. 🔴 Step 3 — They publish the multipolar declaration The joint statement on "establishing a multipolar world" and a "new type of international relations" is the diplomatic language for one thing: the formal announcement that the U.S.-led order is being replaced. In writing. Signed by both. 🔴 Step 4 — Trump's Beijing visit produces nothing to counter it No major breakthrough on trade. No agreement on Iran. No movement on Ukraine. Trump left with photo ops. Xi immediately invited the man fighting the war Trump couldn't stop. 🔴 Step 5 — The 25-year treaty anniversary becomes a relaunch moment Putin's visit also marks the 25th anniversary of the 2001 Treaty of Good-Neighborliness. They're not just renewing it. They're upgrading it — with energy corridors, military coordination, and a shared ideological framework for the next 25 years. 🔴 Step 6 — Washington's traditional alliance architecture cracks further The back-to-back visits signal that Beijing no longer needs to choose sides. It hosts both. It extracts from both. And it shapes the outcome of both conflicts — Ukraine and Iran — without firing a single shot. 🔴 Step 7 — The real question is what Xi told each of them about the other Xi reportedly told Trump that Putin might regret invading Ukraine. Days later, he welcomed Putin with 40 documents and a joint declaration. One of those statements was for the cameras. The question is which one. The question is not whether this shifts the balance of power. The question is how fast. Are you positioned for what comes next? Follow and turn notifications on.
