    Atomic-scale secrets: What really happens inside your battery

    Electrochemical cells – or batteries, as a well-known example – are complex technologies that combine chemistry, physics, materials science and electronics. More than power sources for everything from smartphones to electric vehicles, they remain…

    Study Finds Link between Low Vitamin D Levels and Increased Risk of COVID-19 Hospitalization

    In a new analysis of data from the UK Biobank, vitamin D deficiency was associated with an increased risk of COVID-19 hospitalization but showed only a weak association with infection risk.

    Monroy-Iglesias et al. performed a nested…

  • Decades of chemistry rewritten: A textbook reaction just flipped

    Decades of chemistry rewritten: A textbook reaction just flipped

    Speeding up chemical reactions is key to improving industrial processes or mitigating unwanted or harmful waste. Realizing these improvements requires that chemists design around documented reaction pathways. Now, a team of Penn State researchers…

    Trapped by moon dust: The physics error that fooled NASA for years

    When a multimillion-dollar extraterrestrial vehicle gets stuck in soft sand or gravel — as did the Mars rover Spirit in 2009 — Earth-based engineers take over like a virtual tow truck, issuing a series of commands that move its wheels or…

    Maggots may have been on the Neandertal menu

    The original paleo diet might have included fewer succulent steaks and more juicy maggots.

    Neandertals are often depicted at the top of the food chain for their time, consuming as much meat as lions or hyenas. But maggots growing on…
