Microwave ovens and common viruses

This publication addresses using a standard microwave oven (Sharp R-772(W)M - 900 Watts) to destroy several types of virus:

Infectious bronchitis (IBV)

Avian pneumovirus (APV)

Newcastle disease virus (NDV)

Influenza virus (AIV)


Replicate swabs were dipped in each virus suspension and allowed to dry. They were then returned to their sheaths without sealing and placed either in the autoclave or microwave oven. Six swabs each were treated at intervals of 5, 60, 120, 180 or 240 sec.


Microwave treatment from as little as 5 sec was effective in eliminating virus infectivity for APV, IBV and NDV, but 20 sec was needed for AIV.


The results obtained from the experiments reported here showed that autoclave treatment using the standard conditions was sufficient to kill APV, IBV, NDV and AIV, which was to be expected. However, it was also shown that very short exposure to a domestic microwave was equally effective in inactivating these viruses. Despite this, both types of treatment allowed the survival of nucleic acids of APV and IBV so they could be detected by RT-PCR. It seems probable that PCR products of NDV and AIV would also have been detectable under these conditions, but that was not the purpose of the work.

Microwave treatment, in particular, has the advantage of convenience, since we have shown that inactivation can be done with a simple domestic microwave oven and the treatment time required is very short. Furthermore, this treatment does not involve the use of unpleasant inactivating fluids, so that the samples can be dispatched dry, with consequently simpler and safer packaging.

Didn't take much math? A visual introduction to what "exponential" really means

If you didn't take a whole lot of math, but you are handy with a ruler, this is what exponential actually means. The word gets abused a lot in casual conversation, but it's become clear that many more people can say the word, but may not have learned what it means in any real sense.

Have a look at this graph:

Because it shoots up so much, it is best visualized on graph paper where each vertical tick is a factor of ten:

It becomes a straight line. A straight line is a lot easier to understand.

Notice that the time it takes to go from one factor of ten to the next factor of ten is the same for each factor of ten.

In other words, you go from 10 to 100 in roughly the same amount of time as from 100 to 1000, etc.

Now, deaths lags behind cases by several days. In other words, you don't go from being a "case" to being "dead" instantly. So, even if everyone were in perfect solitary isolation, there would be no impact on the death rate for a fair way into the incubation period for the disease.

So, we can do the same visualization for deaths.

From this:

To this:

Anywho, if you mosey on over to https://www.worldometers.info/coronavirus/country/us/ you can get a regular reality check on what "exponential" means, and why so many people you hear these days are completely full of crap.

Louisiana - notice it climbing the chart

Worldometer watchers no doubt have noticed the after-effect of Mardi Gras by now.

If for some crazy reason, you are ever passing through Dover, Delaware...

Delaware gets a lot of traffic through a northern sliver of the state along I-95, but there's little reason for most people to drive the length of it - all 110 miles or so. You can, of course, ride your bike across it, since it's about 25 miles wide at some parts.

But, NASCAR fans do drop into Dover once in a while, and just south of Dover is the Dover Air Force Base, home of the 436th Airlift Wing.

And you can't miss that if you spend any time in the area, since they seem love doing touch-and-go's all day long in their amazing C-5 Galaxy transport aircraft - the largest transport aircraft the US has.

It's hard to visualize just how freaking huge they are, and how much they can hold. But, you don't have to imagine since, just south of the base, is the Air Mobility Museum. Among their collection of historical transport aircraft is a decommissioned C-5 that you can walk into and get a feel for just HOW FREAKING CAVERNOUS they are inside.

The nose of that monster on the right flips up, and you could play football in there:

If I was the Commander-in-Chief of the US military, and I had a hankering to get a whole bunch of something from one place to another, I think I'd give Dover a call.

Notice that asymptomatic Rand Paul got a test

He doesn’t meet the criteria for a test, but got one anyway.

See how that works, groundlings?

Dumb Rumor in Philadelphia

So, here's an old picture of Drexel University ROTC students on a "ruck" (a loaded march) in Philadelphia:

This picture is recognizable to longtime residents of Philly as being in the vicinity of the Philadelphia Zoo.

So, instead of a perfectly normal picture of ROTC students on an exercise, it is being deployed on social media to "prove" the "military mobilization" that certain social media elements are using to stir up anxiety.

Fortunately, sharp-eyed investigators have figured out the REAL story.

They are, in fact, time travelers from the future trying to figure out who is behind a plot to free the zoo animals at the start of a plague outbreak in 2020!
