    Chemistry in Pictures: Shining Better Together

    via c&en: Before Yujie Tu crystallized this anthracene derivative, it hardly glowed at all. In the closely packed structure of the crystals, the molecules clumped together, locking down squirmy parts of the molecules that would otherwise absorb light and thus prevent fluorescence. Tu studies this phenomenon, called aggregate-induced emission, as part of his PhD work at Hong Kong University of Science and Technology. Finding organic molecules that glow when they clump together is useful in biological […]

  • Quantum Biology: Spooky, Mysterious, and Fundamental to Life Itself

    Quantum Biology: Spooky, Mysterious, and Fundamental to Life Itself

    via Interesting Engineering: As little as a decade ago, scientists were sure that the chemistry of life and the weird chemistry of the quantum world were completely separate things. Quantum effects were usually observed only on the nanometer scale, surrounded by hard vacuum, ultra-low temperatures, and a tightly controlled laboratory environment. Biology, however, is a macroscopic world that is warm, messy, and anything but controlled. It seemed elementary that a quantum phenomenon such as ‘coherence’, in […]

    Science Isn’t About ‘The Truth’ – It’s About Building Models

    via WIRED: YOU MIGHT THINK you can just leave the science stuff to scientists—but you can’t. We live in a world that is surrounded by science and we use toys that depend on science (like that fancy smartphone in your hand). Other issues, like climate change and vaccinations, can have a significant impact on any one of us. You don’t have to be science nerd, but you have to at least know the important parts of […]

  • Self-healing material can build itself from carbon in the air

    Self-healing material can build itself from carbon in the air

    via MIT News: A material designed by MIT chemical engineers can react with carbon dioxide from the air, to grow, strengthen, and even repair itself. The polymer, which might someday be used as construction or repair material or for protective coatings, continuously converts the greenhouse gas into a carbon-based material that reinforces itself. The current version of the new material is a synthetic gel-like substance that performs a chemical process similar to the way plants incorporate […]

  • Planet Earth Wobbles As It Spins, and Now Scientists Know Why

    Planet Earth Wobbles As It Spins, and Now Scientists Know Why

    via LIVESCIENCE: Humans are responsible for some of the wobble in Earth’s spin. Since 1899, the Earth’s axis of spin has shifted about 34 feet (10.5 meters). Now, research quantifies the reasons why and finds that a third is due to melting ice and rising sea levels, particularly in Greenland — placing the blame on the doorstep of anthropogenic climate change. Another third of the wobble is due to land masses expanding upward as the glaciers […]
