Declining Insects, Sunny Day Flooding, Liquid Rules. Feb 15, 2019, Part 2

That once vibrant forest has gotten quieter and emptier, as many of the insects— and the animals that depend on them—have disappeared. In a worldwide report card on the state of insects in the journal Biological Conservation, the conclusion is dire: “This review highlights the dreadful state of insect biodiversity in the world, as almost half of the species are rapidly declining and a third are being threatened with extinction.” We discuss the consequences of the "insect apocalypse."

By 2035, scientist have predicted that over a hundred U.S. coastal communities could experience more than 26 days of low level floods. Researchers at Stanford University determined the economic impacts of this type of flooding in the tourist area of Annapolis, Maryland. Climate risk scientist Miyuki Hino, an author on the study, talks about the impacts of these small-scale effects of climate change.

Fluids are all around you, of course—but how often do we take a moment to think about how liquids work? What makes one slippery and another sticky? Why does one make a good salad dressing, but another a good rocket fuel? Materials scientist Mark Miodownik tackles those questions in his book Liquid Rules.
