An extra robotic thumb let wearers unscrew a bottle cap with one hand, holding the bottle steady while their fingers twisted the cap in laboratory tests. @arxiv https://t.co/7l5YFzREQh

[TechXplore @TechXplore_com]

A beam cast in sewn fabric used about one-third the concrete and half the steel of a conventional beam designed for the same load—without a concrete 3D printer or machine-carved mold. @MIT https://t.co/GpNQ63s78A

Across four U.S. grids, data centers paid just 38% of infrastructure costs tied to their 2025 growth, leaving the rest largely to residents—with rural and lower-income households disproportionately burdened. @cornell @NatureEnergyJnl https://t.co/aAAuVNbAQN

[TechXplore @TechXplore_com]

AI-assisted robot updates increased sorting capacity in tests by over 15,000 packages per robot annually, with changes now deployed across 30% of a U.S. warehouse robotics fleet. @arxiv https://t.co/wcNLNz4do2

[TechXplore @TechXplore_com]

Winter could cut electric air taxi range by up to 22% compared with spring, simulations suggest, even for the same aircraft flying the same mission. @OsakaMetUniv_en https://t.co/o4X9NEFSun

A nonflammable gel membrane carries fluoride ions at room temperature, avoiding the preheating earlier fluoride-ion batteries needed to operate at around 100–150°C. https://t.co/1duXpq5RqN

[TechXplore @TechXplore_com]

Ferroelectric domains smaller than one square nanometer have been observed in zirconia, with calculations suggesting their atomically thin boundaries could become memory-storage components. @wustl @advmater @sciencemagazine https://t.co/YsHShVrPzt

A hybrid analog–digital system computes 65,536-point Fourier transforms, compared with 128 points in earlier analog chips, extending signal processing to much larger inputs. @NatureElectron https://t.co/Jt1EfsdKI7

[TechXplore @TechXplore_com]

Roughly 10 minutes of AI assistance left people performing worse unaided and giving up sooner in one study. @ConversationEDU @arxiv https://t.co/SO9hg5Yibd

[TechXplore @TechXplore_com]

Three new techniques remove or mitigate hidden AI backdoors without major performance losses, targeting malicious triggers that can go unnoticed while models behave normally. @ncstate @arxiv https://t.co/WNFfdDZH8i
