Science magazine, the primary journal of the American Association for the Advancement of Science, had a really interesting article on the latest work being done on trying to figure out where Covid-19 came from. While occasionally dense it’s worth reading.
This post is based on a fascinating article from the July 29, 2021 issue of Nature. I like to say I studied molecular biology back in the Dark Ages, aka the 1970s. At the time what I was taught was cutting-edge, representing the beginning of insights into how the laws

As a class, these basically give you the ability to send (and sometimes receive) SMS/text messages by way of orbital satellite networks. Which
I had no idea that one of the most iconic images of the 20th Century was seen and captured on film by accident. Check out this link: https://www.youtube.com/embed/dE-vOscpiNc Borman’s quote about what he saw is famous. But when I see that image of the Earth coming over the dead lunar
There’s a new apartment building going up on Walnut Street in San Carlos, just north of San Carlos Avenue. That in and of itself isn’t unusual…but the way it’s being built is, at least for San Carlos. That’s because it’s being assembled out of modules that are built off-site and
