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. read more

15 Awesome Things I Saw At The Massive U.S. Gun Show Only Insiders Can Attend

15 Awesome Things I Saw At The Massive U.S. Gun Show Only Insiders Can Attend

Two days surrounded by guns, ammunition, Navy SEALs, military dogs, tactical gear, camouflage, and American flags restored my faith in America.

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. read more

World’s Fastest Spinning Object

Using a high-powered laser, researchers at Purdue University have made a microscopic "dumbbell" the fastest spinning object ever created

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. read more

  • USS Little Rock will receive a laser weapon during an upcoming deployment.
  • The new laser is five times more powerful than the first laser, deployed five years ago.
  • The laser is probably strong enough to seriously damage small vehicles but is dependent on atmospheric conditions. read more

Super-Human Cells Deliver Drugs

Researchers have developed a technique that allows red blood cells to be filled with drug molecules and then returned to a body to home in on a specific location

Researchers from McMaster University have developed what they are calling “super-human red blood cells.” The technique they’ve developed loads normal red blood cells with synthetic drug molecules to create a powerful hybrid cell designed to deliver drugs to targeted locations in the body. read more

Medicine, soft robotics and wearable electronics are just a few of the fields that could benefit from a new hydrogel that’s applied to the body. The transparent material can sense when it’s being touched, bent, heated, or otherwise manipulated.

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. read more

Weapon Wednesday: Effective Underwater Bullets

The narrow corridor of air the CAV-X bullets create for themselves through supercavitation is the secret to how they go through water so easily

DSG

Regular bullets decelerate so quickly in water that they only make it a few feet, which is why diving into a conveniently located pool or waterway when under fire from assassins can be such a good idea.

Although many people routinely pinch their belly in order to see how fat they’re getting, that’s really only a measure of their subcutaneous “under the skin” fat. The Bello device goes deeper, using light to measure visceral fat. read more

DipStick Ice Fisherman’s Cooler

The DipStick

Although it may be hard to believe, ice fishermen do enjoy a cold drink or two while they’re sitting outside in the winter. The DipStick was designed for such anglers, as it keeps those beverages chilled – but not frozen – in the lake water under the ice. read more
