We’ve already heard about experimental self-healing concrete, that can repair cracks within itself. Now, scientists have gone a step further, utilizing bacteria to create building materials that can be grown on-site – and that regenerate when broken.

More than 65,000 people gathered in Las Vegas, Nevada this week for the nation’s largest annual gun industry convention, SHOT Show 2020. Organized by the National Shooting Sports Foundation (NSSF), SHOT Show brings together the world’s best in shooting sports, law enforcement, hunting, and armed forces to share their products and businesses, but more importantly, to shoot the globe’s latest and greatest firearms in the Nevada desert.
Back in July 2018, researchers at Purdue University created the world’s fastest-spinning object, which whipped around at 60 billion rpm – and now that seems like the teacup ride at Disneyland. The same team has now broken its own record using the same technique, creating a new nano-scale rotor that spins five times faster.
Who’s heard this? “You really should eat organic. It’s much healthier and better for the planet.”
Sure it is.
But maybe it isn’t, and maybe you don’t really even know what you’re eating.
As many know, I am a full blown skeptic of the “organic” lifestyle. I personally think it’s a crock. But hey, if that’s the way you want to live, and waste your hard-earned money, knock yourself out.
But are you really? Are you heading home from Whole Foods, with an electric car filled with life saving organics, or did you just throw you cash away on a scam.
That is the question. And here may be the answer.

Missouri charmer led double life, masterminded one of the biggest frauds in farm history
To be “certified organic” farmers in the U.S. must follow rules spelled out in the USDA National Organic Program.
Like all the best con artists, Randy Constant was a charmer, hard not to like.
Big hearted. Good listener. You’d never have guessed that the father of three, grandfather of five was a liar, cheat and serial philanderer who masterminded one of the biggest and longest-running frauds in the history of American agriculture.
Particle accelerators could be incredibly useful for medicine – if they weren’t so huge. The SLAC accelerator, for example, is almost 2 mi (3.2 km) long, while CERN’s Large Hadron Collider (LHC) runs for a stunning 16.7 mi (27 km). Now, scientists at Stanford have managed to shrink the tech down to fit on a computer chip, which could lead to more precise cancer radiation therapies.
