Habitable Planets With Earth-Like Biospheres May Be Much Rarer Than Thought
Short form : Earth-sized planets made out of the right amounts of the right stuff might exist in their bajillions, comfortably orbiting within their stars habitable zones. But the majority of stars out there are smaller and cooler than the sun. Normally this has the problem of tidal locking the planet tot he star, but if the planet escapes that fate (by having a moon, or orbiting a large-enough small star to avoid tidal locking) there’s another problem. Cooler stars put out a different spectrum of light. Even if the watts-per-square-meter of light is the same as on Earth, if the spectrum is wrong, photosynthesis using known systems might not work. Consequently, if life arises on a planet orbiting a red dwarf, it might not evolve adequate photosythetic systems to transform the planet, as life on Earth took a few billion years to do.
This might also mean that an Earth-like world could be located and terraformed and seeded with Earth-life… only to have the plants sicken and keel over.
Genetic modification might or might not fix this, depending on whether or not photosynthesis using redder spectrums can be made practical. Another approach: if humanity has the ability to cross the gulf between the stars, we can do lots of other stuff. This should include parking fusion reactors in orbit and using the generated power to create the biologically necessary frequencies of light. A giant UV flashlight in the sky, parked in geostationary orbit right in front of (or next to) the sun.
No, not having motorcyclists identify as bicyclists, but getting the spectators involved:

“Trigger warning” is now politically incorrect. As is “picnic.” And “rule of thumb.” “She,” “he,” “you guys,” “walk-in,” “African-American,” “no can do,” “transgendered,” “people of color,” “victim,” “survivor,” “spirit animal,” “addict,” “mentally ill,” “prostitute,” and more.
Exclusive: Harry and Meghan rejected Earl of Dumbarton title for Archie for containing word ‘dumb’
They’re afraid that their offspring will get bullied for being the “Earl of some place with ‘Dumb’ in the name.”
Oh, the travails of scions of vast wealth and talentless Hollywood hackery. Yeah, I’m sure your kittle kiddums will be just teased mercilessly for that. For *that.*
This would be more impressive with nukes:
Full Ship Shock Trials – Event 1
The aircraft carrier USS Gerald R. Ford (CVN 78) completes the first scheduled explosive event of Full Ship Shock Trials while underway in the Atlantic Ocean, June 18, 2021. The U.S. Navy conducts shock trials of new ship designs using live explosives to confirm that our warships can continue to meet demanding mission requirements under harsh conditions they might encounter in battle.
Ummm…

Biden touts new crime prevention strategy focused on gun control
“Those who say the blood of Patriots, you know, and all the stuff about how we’re gonna have to move against the government,” Biden said. “If you think you need to have weapons to take on the government, you need F-15s and maybe some nuclear weapons.”
Considering that the whole point of the Second Amendment is to make sure the people can take on a tyrannical government, Biden just admitted that the National Firearms Act is unconstitutional. I *really* hope that this gets before the USSC.
I’d love to see “the Biden Act” get passed that wipes away all the nonsensical gun control laws and restores the Constitutional rights of the citizenry. The downside of that would be that the ammo shortage we’ve got now would be *nothing* compared to what it will be when people can go to WalMart and get themselves a full auto MP5, go to the gun range and blow through a few hundred rounds in under a minute. All thanks to one demented old kiddysniffer accidentally speaking some truth…

Huge Spike In Americans Buying F-15s After Biden Suggests You’ll Need Them To Overthrow Government
The nation scrambled to buy F-15s and nuclear weapons after President Biden said in a speech Wednesday that you’ll never beat a government unless you have the fighter jets and intercontinental ballistic missiles.
All over the nation, American citizens were seen parking their brand-new F-15s in their driveways and garages. Some wealthier Americans purchased the F-22, while less fortunate citizens were forced to buy the F-35 joint fighter. But no matter what craft they chose, American citizens said they were just glad to finally be protected against a tyrannical government.
