World's first 3D-printed ribeye steak is unveiled

The world's first laboratory grown rib-eye steak has been created - and it's as 'tender and juicy' as the real thing. Israeli company Aleph Farms created the 3D bioprinted ribeye with real cow cells, meaning it is completely cruelty and slaughter-free. Scientists took swabs from two cows, cultivated them in a lab, and pieced them all together to form a replica steak. Aleph Farms says the harvesting of cells is no more painful or invasive than a human doing a cheek swab. Aleph claims the lab-grown meat offers the same delicious and juicy attributes as an authentic ribeye bought from a butcher. Aleph has created 3D bioprinting technology which allows it to precisely organise various cellular structures on top of one another to form the steaks. The company has two incubators, named Alberto and Gertrude, at its Tel Aviv facility which are named after the two donor cows. Every single steak made by Aleph is technically either from Gertrude or Alberto. The two incubators mimic the conditions inside a cow to produce the most accurate cells possible. Four different cells are created - support cells, fat cells, blood vessel cells and muscle cells - which then become the 'ink' in a custom-built 3D bioprinter.

Denmark to construct world’s first energy hub on artificial island

Denmark is building the world's first wind energy hub on an artificial island in the North Sea in an effort to provide cleaner energy. The Scandinavian nation currently provides the most oil among all European countries, but it has promised it will be stopping fossil fuel production within the next three decades. The island will be as big as 18 football pitches (120,000sq m), but there are hopes to make it three times that size. It will serve as a hub for 200 giant offshore wind turbines. It's the biggest construction project in Danish history, costing an estimated 210bn kroner. Situated 80km (50 miles) out to sea, the artificial island would be at least half-owned by the state but partly by the private sector. It will not just supply electricity for Danes but for other, neighbouring countries' electricity grids too. Although those countries have not yet been detailed, Prof Jacob Ostergaard of the Technical University of Denmark told the BBC that the UK could benefit, as well as Germany or the Netherlands.
