In preparation for building better running robots, researchers have made useful discoveries about some of nature's most energy efficient bipeds – running birds.The forces at work when a turkey hops over an obstacle(Oregon State University)Running birds have an impressive ability to run while minimizing energy cost, avoiding falls or injuries, and maintaining speed and direction. Researchers at Oregon State University have been trying to discover exactly how the birds do it."Birds appear
Fellow blogger Derek Lowe normally writes a pretty good post, but on more than one occasion - especially when it is something related to polymers - he falls short. Today he wrote:"...even good old IR, which no one uses much any more..." It's not the first time he has bashed IR. Consider "Fellow chemists, raise your hands: Who's taken an IR spectrum in the last six months?" or "I know, for example, that hardly anyone takes IR spectra any more." or "It still does some things very well...but as
Today I came across a new very interesting paper published in Ecological Indicators. An international group of researchers used established metabarcoding protocols to compare soil and leaf-litter samples with malaise trap samples in southern China and to compare leaf-litter samples with canopy-fogging and morphologically identified spider samples in central Vietnam.For those that are not so familiar with the term metabarcoding here a text fragment from my most successful blog post ever (sic!):
Scientific discoveries across all fields just keep coming and coming. Here’s a small assortment of goodies from the past couple of weeks. How do you form planets around stars in triple systems?...
