"Molecular biologist's dream"


"Molecular biologist's dream" is a phrase coined by Gerald Joyce and Leslie Orgel to refer to the problem of emergence of self-replicating RNA molecules, as any movement towards an RNA world on a properly modeled early Earth would have been continuously suppressed by destructive reactions.[47] It was noted that many of the steps needed for the nucleotides formation do not proceed efficiently in prebiotic conditions.[48]

"White supremacists/Antifa rioting"? Show me the videos

A lot of people on Facebook, as well as the President, Mayors and others, have been claiming that most of the destruction was caused by White Supremacists or Antifa. If this is true there should be many photos and videos of it happening.  I searched Google images for the last week for "white supremacists riot". There isn't much to see. So this is probably today's Fake News. Don't spread it. If you believe it, find evidence.  I looked at the first 20 hits. I looked for whites committing violence . Is that "racial profiling"?

2 radical conservative changes to the police--

These are radical changes but in accord with conservative principles. There is an alternative to making the Federal government even more powerful.  1. Local control. Control by a city of 3 million, more people than were in the whole United States in 1789, is not that local. It is quite reasonable that neighborhoods want to choose police that reflect their values and priorities. And even their ethnic group. I don't support affirmative action in any other case, but I do here. A precedent--Candidates for the military academies like West Point are not chosen only by merit. They are nominated by each congressman. The Founding Fathers wanted the military to be representative of the people. Let different neighborhoods choose their police, make the rules, and own the hard choices between public safety and respecting the rights of suspects. 2. Reduce the power of police unions.   (Aside to fellow conservatives: think about police unions the way you think about oth...

   The gas station at Sawtelle and National in Los Angeles has long exhibited interesting trucks and sometimes tanks. For instance there was a very modern European Mercedes semi-tractor, and an old fire engine with a little thermometer built into the radiator cap. I heard the owner is a collector.  In the last 6 months he has been building up military equipment (inspired by Ukraine war?) and now has 3 different tanks (and not all Shermans) , a half-track, and more.  Look for captions at the bottom of the pictures.  Pictures: click link:  Tanks at gas station
