VIDEO: Watch a humpback whale do a headstand
Scientists have captured an incredibly rare sight of a humpback whale doing a “headstand” off the coast of Hawaii. It was captured by a research drone by the Office of National Marine Sanctuaries’ Collaborative Center for Unmanned Technologies during a field operation earlier last week. In it a female humpback whale can be seen swimming vertically and doing a “headstand and drifting with her tail out of the water” while its calf swims around. The scientific name for the behaviour is “tail-saili..>> view originalAstronomers discover the biggest object in the Universe so far - the BOSS Great Wall
As if staring up at the night sky didn’t make us feel small already, astronomers have recently announced the discovery of the BOSS Great Wall, a group of superclusters that span roughly 1 billion light-years across and represents the largest structure ever found in space. The BOSS Great Wall, which sounds aptly named for its size but actually stands for the Baryon Oscillation Spectroscopic Survey, is a string of superclusters connected by gases lying roughly 4.5 to 6.5 billion light-years away..>> view original'True shocker': February spike in global temperatures stuns scientists

Pi Day is upon us again, for those who note today’s date in the format 3/14 (March 14). But rather than talk about Pi Day itself, as I did last year, this year I want to talk about Pi and mathematical notions of beauty. How better to do so than to talk about the 18th century European scholar Leonard Euler’s famous formula: Often described as “the most beautiful formula in mathematics”, Euler seems never to have actually written it down – naming conventions in mathematics are a bit dodgy.
