Multi-axis 3D printing with curved layers! 🖨️ Researchers from the The University of Manchester introduced a neural network-based computational pipeline as a representation-agnostic slicer for multi-axis 3D printing. Traditional 3D printing works like stacking pancakes, flat layers on top of each other. 🥞 This often requires temporary support structures that get thrown away after printing, wastes material, and creates weaker parts. Multi-axis 3D printing can print along curved paths that follow the object's natural shape. This eliminates support structures and makes stronger parts. But figuring out these curved paths is mathematically complex, you need to avoid collisions, respect what the printer can physically do, and optimize for strength. The neural network solves this automatically. It learns to create a "field" around the object, then extracts curved printing paths from this field. Because the entire process is differentiable (translation for non-math specialists, meaning you can optimize it end-to-end), the AI can directly optimize for manufacturing goals like "no support structures needed" and "make it as strong as possible." Here's the project: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

A metal origami! 🪭 This method is called Hyperbolic Metal Forming and is hypnotizing to watch. Instead of shaping metal with slow mechanical force, HMF uses controlled shockwaves to form complex geometries at extreme speed, often without the need for heavy dies or post-processing. The result is stronger, lighter parts with shapes that are almost impossible using traditional stamping. That’s why you see it popping up in aerospace, automotive structures, and defense components. Think of it like metal origami, but driven by high-energy pulses instead of presses. A small reminder that some things in manufacturing come from physics, not just automation. ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

🚨🇷🇺 Russian scientists find way to make aircraft and ship parts stronger and cheaper Researchers at Cherepovets State University have discovered that adjusting the annealing temperature of aluminium-magnesium alloy sheets can significantly alter its strength and plasticity, ending the need for costly rare metals or further processing 🔸 Heating the alloy to 330°C reduces plasticity by the formation of secondary-phase particles — making it stronger 🔸 Heating it further to 370°C triggers recrystallisation, restoring plasticity for more flexible parts 🔸 The same alloy can be tuned for different applications: rigid for load-bearing structures or flexible for shaped components 🔸 The AA5056 alloy is widely used in aviation and shipbuilding for its resistance to low temperatures and corrosion The breakthrough allows manufacturers to tailor material properties from the start — reducing production time, cutting costs and strengthening Russian self-sufficiency in critical materials

Turning + Gravity = smart low cost automation‼️ sponsored Smart turning replaces complex drives with the simplest force available: GRAVITY In high-speed production lines, active product manipulation often introduces unnecessary mechanical stress and energy costs. 💡 The technical approach: By combining a calculated incline CNC-machined internal geometries, products are rotated passively. This eliminates the need for additional motors while ensuring 100% reproducible alignment. ✅ Key Technical Benefits: ➡️ Custom Geometric Contours: The internal glide path is an exact negative of your product, providing stabilized guidance even for asymmetrical shapes. ➡️ Advanced Tribology: High-performance plastics minimize friction coefficients, protecting sensitive surfaces and reducing wear. ➡️ Simplified Maintenance: A solid-block design reduces joints and dead spaces, allowing for rapid, tool-free format changes. Leveraging gravity reduces system complexity + maximizes OEE by making physics do the work.

What is the 4-step cricothyrotomy method? This method uses 4 steps: Scalpel-finger-bougie-tube 1. Scalpel to the cricothyroid membrane 2. Finger insertion into the trachea with downward traction 3. Insertion of a bougie into the track with the finger it in feeling for the tracheal rings 4. Insertion of the tube over the bougie It is a simplified method for performing the procedure that eliminates steps such as the use of trach hook. While this procedure was popularized by the US military through the Tactical Combat Casualty Care guidelines, it has been described for many years before the recent wars in Iraq and Afghanistan. There's obviously no RCT data on this method in humans, but cadaver, mannequin, and case series data demonstrate reliability and efficiency.

Using vDISCO tissue clearing, and a new ultrabright chemical labeling strategy, this Neuron paper introduces LINCS, a powerful method for rapid 3D connectivity mapping in large tissue samples, from whole brains to whole bodies. A very nice advance for scalable circuit mapping, especially by combining strong, uniform labeling with sparse single-neuron reconstruction. Outstanding work by the Rui Lin lab.

Jayden Daniels has such an uncanny feel for space Combine his speed/agility with movement efficiency, and he is so uniquely dangerous Hopefully we see decision-making grow to help support health/longevity... the feel for space to avoid contact shows up on a lot of reps.

🚀New paper out - We present Video-MSG (Multimodal Sketch Guidance), a novel planning-based training-free guidance method for T2V models, improving control of spatial layout and object trajectories. 🔧 Key idea: • Generate a Video Sketch — a spatio-temporal plan with background, foreground, and motion in the pixel space. • Encode this structure directly into the latent space of the diffusion model during generation, which does not require fine-tuning or additional memory during inference. 🧵

Today may have been long and exhausting, but I am deeply happy to have rescued the library of the Palestinian Centre for Policy and Development. It is a profound honor to know that these books were once read by Dr. Refaat Alareer. We have saved over 1,000 specialized books covering Palestinian, Zionist, and Israeli studies. We need your support to print more books for the Phoenix Library | مكتبة العنقاء . We are still in need of a larger collection. The cost of paper and printing is extremely high in Gaza, as the occupation continues to block the entry of paper and books. Please continue to support us through the link.

“Our crew’s nothing special.

By managing all aspects of production, they’ve built the first self-sufficient hempcrete model of its kind in the US. And they’re building safer, more resilient and energy-efficient homes that stand up to Minnesota’s humid summers and freezing winters. Watch “The Green Buffalo” at

The U.S. Food and Drug Administration (FDA) has officially rejected the approval of MDMA-assisted therapy for treating post-traumatic stress disorder (PTSD). The regulatory agency issued a Complete Response Letter to Lykos Therapeutics, refusing to approve the application in its current form. FDA officials are requesting additional late-stage, phase 3 clinical trials to further evaluate the treatment's safety and efficacy. This decision aligns with an independent advisory committee vote in June, which raised serious concerns about trial design, safety data, and "functional unblinding" during the studies. This major roadblock delays the introduction of the first psychedelic-assisted therapy in the U.S. and highlights ongoing challenges in approving mind-altering compounds for medical use.

In 1935, quarry workers in Porthmadog, North Wales, used a unique method for descending from the top of the quarry without additional energy. They employed a specially designed board with wheels, including a large wheel beneath it and two smaller wheels at the front, along with an outrigger arm. To control the descent speed and prevent collisions, a brake system was implemented, where workers collectively regulated the speed by placing their hands on a lever connected to a braking mechanism.
