It’s hard to think of a more challenging environment for an automotive battery than the surface of the Moon, and preparations for NASA’s Artemis program give us a chance to contrast the pioneering technology of the 1970s with where we are 50 years later.

Nearly 3,000 growing chasms have opened up in dozens of towns, swallowing up roads and houses in their path. Known as urban gullies, these destructive forces of nature are increasing rapidly and now threaten to displace more than 3.2 million people.

Nautical disruptor Sharrow Marine has been hard at work fast-expanding its lineup of innovative twisted-loop propellers, releasing tweaked models for new applications while also ramping up overall production. A year ago, that work saw it launch the MX-A propeller for smaller outboards, effectively cutting pricing by more than half compared to previous launches. Now it's doing it again with the AX, smashing downward through the four-figure floor for the first time with a propeller designed for even smaller outboards and kicker motors. Buyers seeking to put the company's striking, efficiency-boosting loop-blades to work can now do so for well under $1K.

Scientists have been working for the last few years on enhancing concrete – arguably the most common construction material on the planet – to store energy. That includes researchers at Massachusetts Institute of Technology (MIT), who found a way to combine cement, water, and carbon black to create a 'supercapacitor' for this purpose back in 2023.

A protein notorious for its role in Alzheimer’s disease may hold the key to supercharging the aging immune system, according to new research. Scientists have found that a byproduct of amyloid-beta rejuvenates T cells, boosting their tumor-fighting power and dramatically reducing cancer risk.

Australia's Stockman Products got its start in what it calls Pod trailers, small, space-maximizing cargo trailers with tub-like plastic covers. It then expanded into some of the sharpest teardrop campers we've ever seen. It's now growing once again, with its largest trailer yet. The all-new Trekka debuts as a smooth-edged dual-axle trailer with a complete camper interior, two kitchens, and dedicated, secure interior space for ebikes, surfboards or other adventure gear.

Convolutional neural networks, or CNNs, are the workhorses behind many of AI's greatest hits, like spotting faces in photos, reading handwriting, or translating languages. They're masters at pattern recognition, scanning raw data with tiny filters (called kernels) to pick out meaningful features, kind of like a digital magnifying glass that highlights what matters.
