The study brings scientists a step closer to achieving the sophisticated molecular organization found in nature and could eventually open new possibilities for the development of advanced functional materials.
In living organisms, molecules such as proteins reliably fold into specific shapes according to information encoded in their molecular sequences. Replicating this level of structural control in synthetic systems has remained a major challenge.

Antarctica's Doomsday Glacier is melting twice as fast as we previously thought - The Weather Network
The collapse of Antarctica's Thwaites Glacier is already a major concern as the world continues to warm, but new research has revealed that ocean water is eating away at the underside of the glacier far faster than we previously thought. Along Antarctica's west coast, there are a number of glaciers that extend as ice shelves out over the Southern Ocean. Due to its size, one of the most important is Thwaites. At 120 kilometres across, it is the widest glacier in the world, with a total area close to 200,000 square kilometres. That's big enough to cover all of Nova Scotia, plus the islands of Newfoundland and Prince Edward Island, along with a quarter of New Brunswick, in kilometre-thick ice. Thwaites, itself, contains so much ice that, in the unlikely event of it completely collapsing into the ocean, global sea levels would rise by around 65 centimetres. Add to this the fact that Thwaites holds back a substantial chunk of the main West Antarctic ice sheet, enough to add another 2.4 metres to ocean levels, and it's easy to see why it has been nicknamed the Doomsday Glacier.
