Herd Immunity - MIT Answers our Corona Virus Questions


Silverfiddle Rant!

MIT has a free website where they provide factual, non-sensational, information about COVID-19:

Technology Review - Coronavirus

Below are a few excerpts:


What is herd immunity and can it stop the coronavirus?
There are basically three ways to stop the Covid-19 disease for good.
One involves extraordinary restrictions on free movement and assembly, as well as aggressive testing, to interrupt its transmission entirely. That may be impossible now that the virus is in over 100 countries.
The second is a vaccine that could protect everyone, but it still needs to be developed.
A third is potentially effective but horrible to consider: just wait until enough people get it.
If the virus keeps spreading, eventually so many people will have been infected and (if they survive) become immune that the outbreak will fizzle out on its own as the germ finds it harder and harder to find a susceptible host. This phenomenon is known as herd immunity.

Breaking News: A Neanderthal tooth discovered in Serbia reveals human migration history - News Paper

Gambar
In 2015, our Serbian-Canadian archaeological research team was working at a cave site named Pešturina, in Eastern Serbia, where we had found thousands of stone tools and animal bones. One day, an excited Serbian undergrad brought us a fossil they had uncovered: a small molar tooth, which we immediately recognized as human. A 3D recreation of a recently discovered Neanderthal tooth [Credit: Joshua Lindal] A single tooth may not seem like much, but a lot of information can be drawn from it. We knew it was about 100,000 years old , because the layer it was found in had previously been dated. We were able to build a high-resolution 3D model to study the shape of the crown, roots and internal structure. We made detailed measurements and performed statistical analyses which are published in the June 2019 issue of the Journal of Human Evolution . The results of our analysis are clear: our little tooth belonged to a Neanderthal. Neanderthal fossils have been found in Croatia...

Breaking News: Stephen Moore’s failed Federal Reserve Board nomination, explained - News Paper

A charlatan whom the conservative movement pretends is an expert. Stephen Moore, the conservative think tanker and television pundit who Donald Trump had tapped for a position on the Federal Reserve Board of Governors, has withdrawn from consideration according to a presidential tweet early this afternoon. Steve Moore, a great pro-growth economist and a truly fine person, has decided to withdraw from the Fed process. Steve won the battle of ideas including Tax Cuts.... — Donald J. Trump (@realDonaldTrump) May 2, 2019 Coming just a couple of hours after Moore proclaimed himself “all-in” on the quest for confirmation, Moore’s withdrawal is part of the same slipshod process that led Trump to name him in the first place. The larger story, however, is that President Trump would like the Federal Reserve to keep interest rates low to help the economy grow faster and help him win reelection. He also thinks underqualified would-be flunkies such Moore and former Godfather’s Pizza impre...

News Today: 'You're Going to Get It, or I'm Going to Die Trying, B*tch': Alex Jones Issues Stunning Threat to Mueller — And Pantomimes Shooting Him

Gambar
Click here for reuse options! The conspiracy theorist ended a deranged rant about pedophilia by threatening the special counsel. Conspiracy theorist Alex Jones threatened special counsel Robert Mueller during a Monday episode of his InfoWars show, miming a shooting and saying he would "die trying" to take Mueller down. Jones began by making unfounded claims about Mueller and Jeffrey Epstein, who was convicted of solicitation of a minor for prostitution in 2008. "That's the thing, is like, once it's Mueller, everyone's so scared of Mueller, they'd let Mueller rape kids in front of people, which he did," Jones said. "I mean, Mueller covered up for a decade for Epstein kidnapping kids, flying them on sex planes, some kids as young as seven years old reportedly, with big perverts raping them to frame people." "That's a demon I will take down, or I'll die trying," Jones continued. Jones made repeated shooting g...
