science news 3.4.2020

Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary in italics in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without italics if I have any.

From the news media:

On the Saturday 14.3. I travelled back from Germany and was shocked to find that in the UK mass events like the Cheltenham Festival were still going ahead in spite of the virus already spreading out of control, and the science already suggesting that it is also spread by people who don't show symptoms. Now, as the Guardian reports, the impact of Cheltenham is seen in the case stats. In a week, it will be seen in the death stats, which are more reliable. I am keeping the link to the article here mainly because it provides a handy reference of other events that still went ahead on that weekend and shouldn't have, including a Champions League game enabling the spread from Spain to the UK.

On a related note, I read the article in Der Spiegel about how the Austrian ski resort Ischgl became a superspreading centre of COVID-19 mainly because I happen to know the place. Found it both very educational and shocking to read how the relevant people in Iceland spotted the problem on March 1st, and went on to alert other European countries. It took 2 weeks until the place was shut down. English version of the article is here. German original was in the issue 14 page 58.
