Researchers at the University of Tokyo’s Rekimoto Lab built a backpack that turns ordinary jumps into something closer to a slow-motion bounce across the lunar surface. Called Lunavity, or Augmented Jump in the formal paper, the system straps a multi-rotor aircraft to your back and uses constant upward thrust to lighten your body so you can jump higher, stay airborne longer, and come down more gently.
Storage always fills up faster than expected. Games grow larger, video files push higher resolutions, and phones or handhelds run out of room just when you need them most. A regular microSD card keeps working in those situations, yet the time spent waiting for transfers and loads starts to add up. SanDisk’s 256GB microSD Express card, priced at $58.99 (was $74), changes that equation with speeds that feel closer to a basic portable SSD than a traditional memory card.
Nigel Braun, better known as NileRed, first got the idea back in 2019. Air holds water vapor and carbon dioxide. Those two compounds already contain the hydrogen, carbon, and oxygen atoms that make up ethanol. No sugar or yeast, just the stuff floating around us every day. He set out to pull those pieces apart and put them back together as drinkable alcohol.
Kasquez just released a complete fan recreation of Donkey Kong Land that runs natively on Windows. The 1995 Game Boy original from Rare now exists as a standalone PC build with visuals, audio, and movement drawn straight from the style of Donkey Kong Country. Over thirty full-sized levels wait, along with the usual banana collecting, secret hunting, and a fresh trip to reclaim the hoard from King K. Rool.
iFixit recently opened up two pairs of Chinese smartglasses to test a common industry claim. Manufacturers often say devices this small and water-resistant simply cannot offer user-replaceable batteries. The team bought a Quark AI Glasses S1 and a set of Rokid Glasses to see if that held up. Both models pack an internal battery plus a separate external pack that attaches for longer runtime. Both run on a Qualcomm Snapdragon AR1 Gen 1 processor with 32 GB of storage and use micro-OLED projectors to put information in front of the wearer’s eyes. Their internal layouts, however, tell two very different stories.
