    New Satellite Engine Could Use Earth's Atmosphere as Fuel●New Satellite Engine Could Use Earth's Atmosphere to Stay in Orbit IndefinitelyYhnScienceSpace Policy66just now

    Researchers have unveiled an air-breathing electric propulsion engine that scoops up molecules of Earth's upper atmosphere and uses them as propellant, potentially letting satellites in very low orbit refuel themselves and operate indefinitely without carrying limited fuel supplies. The concept could reshape how low-orbit missions are designed, extend satellite lifetimes dramatically, and reduce the cost of Earth observation and communications operations.

    New Cryo Microscope Reveals Living Antarctic Fish Cells●Researchers engineered a novel microscope capable of operating near 0 degrees Celsius, enabling the first-ever high-resoMmastodonScienceBiology8just now

    Researchers have engineered a microscope that can operate near 0 degrees Celsius, allowing the first high-resolution observations of living cells in Antarctic fish. The work aims to uncover how these animals' cells function and survive in extreme cold, a question that has long been difficult to study because conventional microscopes cannot maintain such freezing conditions while keeping specimens alive. Findings are expected to inform cell biology and cryobiology research.

    DARPA Plans Repair Robot for Satellites in Geosynchronous Orbit●Inside DARPA’s Mission to Send a Repair Robot to Geosynchronous Orbit✉newsTechnologyRobotics6 min ago

    DARPA is developing a robotic spacecraft designed to service and repair satellites in geosynchronous orbit, roughly 36,000 kilometers above Earth. The program, detailed by IEEE Spectrum, would extend the lives of expensive communications and military satellites that currently cannot be fixed once deployed. Interest is focused on the engineering challenges of robotic repair at such extreme distances and its implications for space operations.

    Motorless microscale robots fly and steer using sound waves●Engineers build motorless microscale robots that fly and steer using sound waves✉newsSciencePhysics2 min ago

    Engineers have developed tiny robots that can fly and steer without any motor or onboard propulsion, instead using sound waves to control their movement. The approach removes the need for conventional moving parts at very small scales, where fitting motors and power sources is a major obstacle. Researchers say acoustic control could open the door to swarms of miniature flying robots for use in medicine, sensing and inspection tasks.

    Mistral CEO Arthur Mensch says AI can be controlled▼CEO of Mistral: AI is software. It can be controlledYhnBusinessEconomy889 min ago

    Mistral AI chief executive Arthur Mensch argues that AI is fundamentally software and can therefore be controlled, according to an interview with Le Monde. The French start-up boss is pushing back against fears that advanced AI systems are unpredictable or beyond human oversight, framing the technology as an engineering discipline like any other that can be governed through proper design.

    Tesla Targets 20,000 Optimus Robots a Week, Hands Remain a Hurdle●Tesla Wants to Build 20,000 Optimus Robots a Week. First It Has to Figure Out Hands✉newsTechnologyRobotics6 min ago

    Tesla says it aims to produce 20,000 Optimus humanoid robots per week, but the company still has to solve major engineering challenges with the robots' hands, which are among the most complex parts to build. Commentators are weighing the gap between the ambitious production target and the current state of the hardware, with many treating the hands as the key bottleneck for the program.

    Quantum Memory Breakthrough Enables Random Access Across Seven Cells●Random access quantum memory lets one processor select among seven storage cells✉newsSciencePhysics2 min ago

    Researchers have demonstrated a random access quantum memory system in which a single quantum processor can select among seven storage cells, rather than reading stored quantum information sequentially. The result matters for scaling quantum networks and modular quantum computers, where fast, selective retrieval of quantum states is a key engineering hurdle. Details on the research team and the specific physical platform used were not included in the available report.

    ANYmal inspection robots can now pass security checks●Industrial inspection robots ‘ANYmal’ can now pass security checks✉newsTechnologyRobotics6 min ago

    ANYmal, the four-legged industrial inspection robot developed by Swiss company ANYbotics, has been cleared to pass security checks, according to a report by Interesting Engineering. The quadruped robots are used for autonomous inspection in industrial facilities such as plants and refineries. Clearance through security screening removes a practical barrier to deploying the robots across sites and during transport, and is being noted as a step toward wider adoption in industry.
