Denmark will kill its 15 million caged minks — and not save the furs — because it's found a mutated version of the coronavirus.
The coronavirus evolves constantly and, to date, there is no evidence that any of the mutations pose an increased danger to people. But Danish authorities were not taking any chances. “Instead of waiting for evidence, it is better to act quickly,” said Tyra Grove Krause, head department at Statens Serum Institut, a government agency that maps the spread of the coronavirus in Denmark....
Instead of waiting for evidence, it is better to act quickly. A scary adage, but probably the right attitude for this specific problem. You can't individually test 15 million Danish minks and wait for the results. By the way, there are 5.8 human beings in Denmark, so there are nearly 3 minks per person.
The pelts of the mink will be destroyed and Danish fur farmers have said the cull, which is estimated to cost up to 5 billion kroner ($785 million), may spell the end of the industry in the country.
Speaking of weasels, the NYT reports: "A nasal spray that blocks the absorption of the SARS-CoV-2 virus has completely protected ferrets it was tested on, according to a small study released on Thursday by an international team of scientists." It's the animals that might infect us that are useful for tests.
The nasal spray science is interesting:
The spray attacks the virus directly. It contains a lipopeptide, a cholesterol particle linked to a chain of amino acids, the building blocks of proteins. This particular lipopeptide exactly matches a stretch of amino acids in the spike protein of the virus, which the pathogen uses to attach to a human airway or lung cell.
Before a virus can inject its RNA into a cell, the spike must effectively unzip, exposing two chains of amino acids, in order to fuse to the cell wall. As the spike zips back up to complete the process, the lipopeptide in the spray inserts itself, latching on to one of the spike’s amino acid chains and preventing the virus from attaching.
“It is like you are zipping a zipper but you put another zipper inside, so the two sides cannot meet,” said Matteo Porotto, a microbiologist at Columbia University and one of the paper’s authors.
