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.
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.
