China's PLA opened four new colleges on September 30, one of them teaching drones, autonomous systems and AI-assisted decision-making. The schools around it suggest Beijing now treats unmanned systems as a permanent staffing need inside the army.
Reality
University of Manchester researchers made a pressure-sensitive paint that reacts to heat 25% less than the industry benchmark. Wind tunnel teams testing above Mach 5 still have to correct for temperature, only by a smaller amount.
Reality
Researchers put the azobenzene ethyl ammonium lead iodine film at roughly 0.04 watts per metre-kelvin and 700 to 10,000 times silicone's stiffness. Without a thickness figure an engineer cannot specify it.
Reality
Researchers at TU Delft mounted two artificial whiskers on a micro-drone and filtered out its own propeller wash, giving millimeter-precision depth readings in enclosures where cameras see nothing. The flight tests are published in Nature Communications.
Reality
Penn State walked the bromine-to-iodide ratio across six metal-halide films to aim the bandgap at indoor wavelengths. The stability run that followed was done under light many times brighter than an office ceiling.
Reality
A team publishing in Science reports 0.75 watts per square centimetre at 0.7 volts and 63 percent power retention after 30,000 stress cycles. The lab making the composite still turns out about 100 grams every three days.
Reality
Naval Air Systems Command's Silent Anvil request for information publishes the weight, length and diameter a bidder has to design inside, and it offers two ways to build it around a torpedo the Navy may supply itself.
Reality
Electrochemical strain microscopy can read probe contact as ion movement, so a KAIST team etched trenches into ion-blocking silicon to prove it. Their fix is an argon-beam polishing step, not a new microscope.
Reality
Nanjing University's cathode still holds 87.8 percent of its capacity after those 100 cycles, which is a genuine cell-level result and a very short record, and the report attaches no cost figure to the cheap-sodium case.
Reality
The JAMA Dermatology results published August 12 push an already-approved arthritis pill toward a new indication, which turns interesting science into a prior-authorization question about who counts as a responder.
Reality
China has put an electromagnetic catapult on an amphibious hull, which narrows the air wing to aircraft that cannot take off vertically. The GJ-21 is the candidate. Its public record is thin.
Reality
ElectroFlex enters production at 24.4% cell efficiency and roughly 73 watts per kilogram, which puts the buying decision with whoever owns the weight budget rather than the energy budget, at least until the certification data lands.
Reality
Tianmushan Lab and Tsinghua reported 602.5 Wh/kg from a lithium-rich manganese cathode, while the 180-cycle durability figure came from a lower-energy build. The second number is the one a fleet has to spec against.
Reality
The bottom-gate design lands threshold voltage within 0.1 V of target at 400C and still switches 1,000-to-1 at 600C. Those two numbers are 200 K apart.
Reality
China's airship-borne wind system ran a complete flight cycle at 4,000 metres, according to CCTV News. Judging it against tower turbines needs numbers the report does not carry.
Reality
ARL, VMI and West Point tuned iridium chromophores by calculation first, aiming at chemical-agent warning and fuel made on site. What they published is a method, not a device, and not a cycle time.
Reality
The state arms maker is showing a 90kg humanoid that copies an operator's motions in real time. The claim worth reading is not autonomy but a control layer that ports between bodies.
Reality
Korean researchers ordered platinum and nickel into a fixed lattice and ran it for four months. The result is a replacement-cost input, but the operating point behind it is missing.
Reality
Livermore's direct ink writing removes the assembly step at the core-cladding boundary. The output is still hundreds of milliwatts against a kilowatt ambition.
Reality
A Beijing Institute of Technology simulation puts wartime order fulfilment at 63.4% when demand triples. The binding constraint it finds is component supply, not airframe assembly.
