The First Wave Extinction, which accompanied the spread of the foragers, was followed by the Second Wave Extinction, which accompanied the spread of the farmers, and gives us an important perspetive on the Third Wave Extinction, which industrial activity is causing today.  Don't believe tree-huggers who claim that our ancestors lived in harmony with nature.  Long before the Industrial Revolution, Homo sapiens held the record among all organisms for driving th emost plant and animmal species to their extinctions.  We have the dubious distinction of being the deadliest species in the annals of biology.
--Yuval Noah Harari in Sapiens: A Brief History of Humankind, 2015, p74.

When I go on a trip, I keep three lists.  GIB, WIH, and DN are abbreviations for the lists: Glad I Brought, Wisht I Had, and Didn't Need.  Based on these lists I am able to refine my packing for that actvitiy or destination.  I'm going to share with you what I learned about packing for a trip to Kauai, Hawaii in December.  If you use this system, you will clarify your own packing lists.

If you want to build a ship,
don't drum up the men to gather wood, divide the wood and give orders.
Instead, teach them to yearn
for the vast and endless sea.
--Antoine de Saint-Exupery

We went to the Mission last night to hear about Viruses from Hell, and it turns out the speaker was a PhD professor who is into viruses that come from acidic hotsprings. He looks a lot like my friend Gordon who is also a brilliant academic--something about that jutting forehead must allow for extra brains. Ken Stedman is a professor at Portland State University who has made a career of viruses. His research has mostly involved examining the genomes of extremophile viruses and comparing them. It was faintly interesting to me--genetics is interesting, and yet I am so homocentric. I really want to know about bacteriophage therapy for healing horrible infections. I want to hear about the evolution of the flu. But his research wasn't about this and his talk was about the questions that will ensure that he gets grants and funding in the future. I couldn't help but to think of the right wing perspective that academics are parasites on society and perform no useful function other than keeping themselves in priuses. There is truth it that, though it is also true that there is nothing more important for our future than to keep investigating our world and what is in it. Scientists have specialized training that makes it possible for them to think of things that I don't have words or concepts for. There is so much more of the world to know about. I am learning this narrow fraction that is medicine, and it is more than I can ever take in. Within that sea I must pick a drop.

Circling back to VIRUSES, I did bring home a few interesting factoids. I call things factoids until they've been demonstrated beyond the shade of MY doubt. He defines viruses in several ways but my favorite was "a capsid encoding organism", also known as a phage. He told us that the major reservoir of viruses on the planet is in seawater, though they infect everything else that lives. Some 5% of the oxygen in our atmosphere is produced by bacteria that are infected with viruses. The viruses increase the oxygen-production of these microbes. I learned that 10% of the human genome is viral---and this is just the ones that have been demonstrated beyond a shade of HIS doubt. Professor Stedman said that up to 43% of the human genome could be viral, and that many of the genes we got from viruses are important ones, without which we would not be here. Apparently all placental mammals share one particular viral gene so it got in there a long time ago.

One of the main points that Professor Stedman made was how much of the world is made up of viruses, and how small they are. He said that if you put all the Earth's viruses end to end the lineup would reach to the Andromeda Galaxy. And they'd weigh more than some huge number of whales, and so on.

One nice thing about going to science pubs is being around people for whom evolution just is, instead of having to debate about it. It makes me realize how much energy I put into defending a basic scientific mindset. Too many groovy spiritual people and homeopaths in my life. They stress me out.

For today my mantra is "it is OK to do nothing" and I have been enjoying it. I need to take breaks more often. And journal. Just for me.

Or in other words, they are a natural part of our immune defense! New science suggests that mucus in our body is full of viruses that attack bacteria! Those viruses don't hurt us, in fact, they protect us. Commensal viruses....

Don't forget to breathe while watching this. I would have passed out if I didn't remind myself to take a deep breath every now and then. THIS is why the ocean frightens me. Big water on the river is still itty bitty teeny weenie compared to this.

Wikipedia: It was only in 1998, at the Gotcha Tahiti Pro, that Teahupo'o became widely recognized as having some of the heaviest waves in the world. ...Teahupo'o translates roughly to "place of skulls" or "to sever the head". It is a shallow reef break located in the South Pacific, off the southwest coast of Tahiti in French Polynesia.

I know nothing of it and just watched it for the first time. This is the Kokoro dance. Not safe for work due to nudity, however, it is nonsexual. ( Cut for suggestive image on youtube window. )

Made by dolphins, whales, people, volcanoes, nukes. Very interesting visuals, mostly camera footage, some explanatory graphics.
