    COVID-19 maybe not from China.

    There appear to be some evidence that the virus was present in Europe earlier in 2019. Here a study from France: https://link.springer.com/article/10.1007/s10654-020-00716-2

    New coronavirus variants could require updated vaccines

    We don't really know yet, so please take this info with a grain of salt. There are 3 known mutations of covid-19, called after the country where they were first spotted (which may not be the country they originate from): Britain, South Africa and Brazil. In Brazil in particular, the situation...

    Second Shot

    Is there going to be one and if not, how long before I get the second one will the first one hold? If I fail to get the second Moderna shot, can I wait the requisite 28 days then get a Johnson and Johnson?

    Got shot #1 today.

    #2 comes on Feb 5...sore arm, some queasiness in my tummy and a bit of fuzzy-headedness at the beginning. It was quick and easy.

    Scented candles review.

    A somewhat lighter post today. It is possible to build a scientific study on a shoestring, when one finds a way. Kate Petrova noticed that the reviews of scented candles on Amazon went down at the beginning of this year. Could it be the effect of covid-19, taking into account that one of the...

    This is the latest advert from the German government about covid-19. With English subtitles.

    Event 201

    You may already know about this, as it happened last year. The Johns Hopkins Center for Health Security in partnership with the World Economic Forum and the Bill and Melinda Gates Foundation hosted Event 201,[29] a high-level pandemic tabletop exercise on October 18, 2019, in New York, NY. The...

    The President and Covid

    Is it really within reason to think he could test in the morning and show symptoms that evening and leave the hospital the following Monday?

    France and Germany announced lockdown today. Irland, the desunited Kingdom, Spain, Poland, etc... have also announced various kinds of lockdown.

    How our immune system struggles with corona

    An interesting article from the Nieuwe Rotterdamsche Courant summarizing the present knowledge about covid-19. Fascinating read. The article (in Dutch) can be found here: https://www.nrc.nl/nieuws/2020/10/09/hoe-onze-afweer-worstelt-met-corona-a4015405 Readers should refer to this link if they...

    Dutch celebrities rebel over COVID constraints

    A group of Dutch celebrities have triggered both a sizeable backlash and a national debate after breaking cover on social media with the hashtag #ikdoenietmeermee, (I no longer participate). The central figure is the rapper and model Famke Louise, 21, who told her 1 million Instagram followers...

    The New York Times, Sunday 24th 2020

    The front page of The New York Timest lists a small fraction of those those who have died from Covid19 in the US alone.

    Covid 19 Lockdown

    The response to Covid 19 will prove to be a huge blunder. The only accomplishment has been the slowing of heard immunity and in the process put more elderly people at risk. They should have locked down the elderly but locked down the children instead.

    Potential Vaccine for Covid 19

    The University of Saskatchewan will start testing a potential vaccine for Coronavirus on animals next month! Come fall time they are planning testing on adults. They are one of a few facilities approved to work with this. A joint venture with others, not a race to be first, but a cooperative...

    Small Town Sensibilities

    With the doors shut permanently for now, this small town furniture store is finding ways to exploit social media in an effort to keep business rolling. Yesterday I noticed these huge symbols on their windows - covering every conceivable avenue customers might use to contact them. —————...

    Contact tracing app.

    Apple and google are jointly developing a contact tracing app that would tell people if they were near a infected people in the past 2 weeks. The underlying mathematics are interesting. How do the apps work? A naive approach would be to store the position of the whole population all the time...
