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

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

Freeze the Fat

Injecting an icy saline slurry into fat deposits could be a new fat-reduction technique
Injecting an icy saline slurry into fat deposits could be a new fat-reduction technique

It sure sounds like a pop-up ad you’d see online, but scientists have created and tested a new treatment that melts away belly fat. The new technique, developed by researchers from Harvard and the Massachusetts General Hospital (MGH), involves injecting an icy saline solution directly into fat deposits to shrink them by half. 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

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

A Cheaper High-End Turntable?

I guess “cheaper” is relative.

Mark Levinson offers audiophiles a cheaper high-end turntable

The Mark Levinson № 5105 turntable is due for release by mid-2020

Mark Levinson has been in the audio business for nearly 50 years, and if you’re not familiar with the company from its hi-fi gear, then you may have heard the Harman brand’s sound systems in cars like the Lexus RC350. The company launched its first turntable at CES 2017, and has now returned to Las Vegas with its second – № 5105. 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
