ECONOMY\nPaper growth\nIreland’s GDP grew by an impressive 7.8% in 2015. But the Central Statistics Office issued revised numbers that boosted it to an astounding 26.3%. The increase, however, is a result of “penmanship” rather than workmanship, reports Quartz. \nHow did it happen? Corporations, taking advantage of Ireland’s low corporate tax rate of 12.5%, rushed into “corporate inversions”: merging with entities already domiciled in Ireland, dramatically increasing Ireland’s capital asset base. At the stroke of a pen, property previously owned by foreign companies domiciled elsewhere suddenly became the property of “Irish” companies. \nDO-IT-YOURSELF\nCrossword aficionado\n\n\nWhen a 91-year-old woman saw what appeared to be a huge crossword puzzle on a wall accompanied by a sign saying “Insert words,” she obliged by filling in the blank spaces, reports The Telegraph.\nUnfortunately, the “puzzle” was located in the Neues Museum of Nuremberg and happened to be a 1977 work of art by Arthur Köpcke called “Reading-work-piece.” The lady had just filled in a “puzzle” valued at 80,000 euros.\nQuestioned by the police, the woman explained that she had simply followed the artist’s instructions and if the museum didn’t want people following the instructions, it should post other notices making that clear. Fortunately, restoring the work should cost only a few hundred euros, an expense the museum graciously agreed to cover.\nWHERE ON EARTH?\nNowhere to hide\nAnyone who thinks they can hide behind fake names on Twitter, Instagram and other portals had better think again. According to a report by researchers from Columbia University and Google, as reported in BuzzFeed News, digital traces left in apps can be easily turned into the equivalent of digital fingerprints. In fact, with geotagged posts from just two social media apps, it’s possible to identify a specific user. But even with geotagging turned off, a 2014 IBM algorithm showed a Twitter user’s location can still be determined with 58% accuracy.\nSUPERFOODS\n\nMove over krill, kale and spirulina. The new superfood contender could be cockroach milk, reports Science Alert, according to research published in IUCrJ, the journal of the International Union of Crystallography.\nOne species of cockroach feeds its offspring with a kind of “milk” that contains protein crystals that are reportedly four times more nutritious than cow’s milk. Packed with all the essential amino acids, plus fats and sugars, the substance has the added advantage of being time-released.\nDoes this mean apartment dwellers with cockroach infestations should rejoice? Maybe not. The milk is produced by only one type of cockroach, which bears live young.
