On Tuesday Saarland became the first German region to ban campaigning by foreign politicians. Several German local councils had called off planned Turkish ministers’ campaign meetings on technical grounds, such as fire safety.
Yet expectations for the summit meeting on Tuesday are low, with no sign of any political breakthrough that would lead to more ambitious efforts. Scientists say emissions must peak within the next few years, and then begin to decline, if the world is to have any hope of keeping global warming to an upper limit that countries agreed on five years ago. So far, no plans are in place that would come close to achieving that.
But researchers this year came up with a new method that makes flexible, realistic ears out of real cells. Those cells come from rats and cows, and they form a collagen gel that can take the shape of any mold. When placed in a mold of a human ear—a mold assembled using a 3-D printer—the gel forms an ear in less than an hour. The artificial ear then just needs a few days growing in nutrients before it's ready to be implanted in a subject.
