Starfleet or barchan?

leave a comment »

Doesn’t this crescent-shaped dune look like the Starfleet logo?   There’s a scientific explanation  for it,  but it’s more fun to imagine that it’s a relic from a Star Trek shoot.   Live long and prosper everywhere!

Astronomer or alchemist?

leave a comment »

I expect you’ve heard of the Kepler Space Telescope launched by NASA  in 2009 to discover Earth-size planets orbiting other stars.   It is retired now,  but it was named after astronomer and mathematician Johannes Kepler,  who was an important figure in the 17th-century scientific revolution.

A chemical  analysis of pages  from Kepler’s manuscript about the moon has found high levels of metals like gold,  silver,  mercury and lead.   He wasn’t known to study alchemy,  but it was still practised in the 16th and 17th centuries,  and a close friend of his did study the ancient  branch of natural philosophy.   Truth be told,  most scientists of the era at least dabbled in that area.

Life below…

If you were to go onboard a Chinese manned submersible more than a mile deep in the ocean,  this is  the sort of exotic and strange sea life you might see.

Beer from shards…

leave a comment »

If you discovered some 3,000 year-old yeast,  would you use it?   If so,  for what?  Bread?   Israeli scientist had to revitalize six ancient strains of yeast, but once they had accomplished that,  they used it to  brew ancient  types of beers. 

This is the first time that living yeast were actually extracted,  identified and recreated from ancient pottery vessels and may lead to some other useful  —  and enjoyable —  techniques.  L’Chaim!

Earth Day 2019…

leave a comment »

It is embarrassing that Earth Day celebrations have been held for nearly 50 years on Vladimir Lenin’s birthday.   It is embarrassing how long so many people have accepted the  unhealthy brew of junk science,  politics,  and fundraising.   Instead,  they should all be thanking the USA for its leadership in cleaning up its environment.  Reliable,  affordable energy is the critical enabler of innovation,  and we are the only populous nation in the world  to meet  the World Health Organization’s standards for particulate matter.

We achieved this while the country’s population,  energy consumption, vehicle miles traveled,  and gross domestic product also grew dramatically.   Thank the free market and a society which values the individual instead of the government.   You’re welcome.

UPDATE:  I neglected to include  this sterling  piece,  which should be stapled to the nose of every climate hysteric,  beginning with AOC.

Spectacular lightning…

leave a comment »

I often bash California because it is so poorly run by arrogant know-nothings who make citizens suffer and welcome illegals with open arms.  In this instance I am neither bashing nor praising that deteriorating state, but pointing to  the wonders  of nature.

Most of us have witnessed a few flashes of lightning during thunderstorms,  but this  sustained flurry of bolts will take your breath away.   Our thanks to the photographers who brought us such beauty and who hopefully stayed safe.

Ghost hunt…

leave a comment »

No,  I don’t mean wraiths floating about haunted places.  I’m referring to the scientific search for ghost species,  because human DNA suggests strongly some of our  ancestors are  missing.

When I was in school we learned about Neanderthals, but no one had ever heard of Denisovans,  despite the fact that some living humans can trace as much as 5% of their ancestry to them.

What I find cool  is that the researchers are using deep learning to track down these missing populations resulting from breeding amongst other human species.  This is a type of artificial intelligence in which algorithms are designed to work as an artificial neural network,  or a program that can process information the same way a mammalian brain would.

It’s fascinating work,  as you can see from the charts.
