Biodegradable fruit wash removes pesticides and keeps grapes fresh for 15 days
UBC researchers developed a biodegradable, starch-based fruit wash using iron and tannic acid that binds and removes 86–94% of surface pesticides and then forms an edible, breathable coating that slows oxidation and moisture loss, keeping grapes firm for up to 15 days at room temperature and suggesting a low-cost option for both households and food processors pending regulatory approval.

LEGO-powered motor reaches 4,000 RPM with minimalist parts
A YouTuber builds a fully working electric motor from LEGO bricks, magnets, a hand-wound copper coil, a sensor coil, a transistor, and a 9-volt battery. Without a microcontroller or complex electronics, a sensor coil detects rotor magnets and triggers timed power bursts to the driving coil, producing self-timed rotation. The project illustrates core electromagnetism and feedback control, with rotor configurations claimed to reach up to 4,000 rpm and varying speeds/torques that can drive a small LEGO car.
China unveils ultrafast holographic 3D printing at 0.6 seconds
Researchers at Tsinghua University have introduced Digital Incoherent Synthesis of Holographic light fields (DISH), a holographic-based volumetric 3D printing method that can fabricate millimeter-scale objects in 0.6 seconds with 12‑micrometer precision. By projecting holographic light from multiple angles in a resin, without moving parts or layered drying, the system achieves about 333 cubic millimeters per second and could enable rapid, high-resolution production for biomedicine, nanotechnology, micro-robotics, and flexible electronics.
NASA’s Athena hits 20 petaflops, boosting rockets, aircraft, and AI
NASA has unveiled Athena, its most powerful supercomputer to date, delivering over 20 petaflops at the Ames Research Center to run complex rocket and aircraft simulations, train large AI models, and analyze vast mission data with a hybrid on-site and cloud approach; the system is available to NASA researchers and external scientists, as Artemis II preparations continue.
Hair-thin fiber chips turn garments into microcomputers
Researchers at Fudan University have created fully flexible fiber chips that embed complete electronic circuits inside hair-thin strands, forming fiber integrated circuits (FICs) with high transistor density capable of processing digital, analog, and neural-style computing; these fibers survive thousands of bending cycles, washing, and heat, enabling self-contained computing in smart textiles and wearables, with early scalable manufacturing and publication in Nature.
Wood-based smart window tunes daylight and blocks UV without power
Researchers created a wood-based transparent window that passively adjusts visible light with temperature, blocks nearly all UVA rays without electricity, and offers insulation far better than glass, enabling energy-efficient buildings and new uses like smart greenhouses and health-monitoring skins.
Under-$1 3D-printed optics enable nanoscale super-resolution imaging
Researchers show that consumer-grade 3D printers, silicone molding, and UV-curable resin can create low-cost, multi-element lenslets for a multifocal structured illumination microscope, achieving about 150 nanometers resolution comparable to commercial systems and potentially democratizing access to high-performance imaging.
