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

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

Mad-Max Lambo Goes to Auction

Before the Countach came along in the 1980s and defined the classic shape that’s underpinned nearly every Lambo since, the biggest selling Lamborghini was the Espada, made between 1968-1978. That’s not to say it was a high volume machine; only 1217 of this 4-seater grand tourer were ever built. Which makes this crazy rat rod even more special. read more

An Fully Autonomous Helicopter?

There is no shortage of aviation startups out to build self-flying aircraft from the ground up, but California-based Skyryse has adopted a slightly different approach. Its flight technologies are designed to be fitted to existing helicopters, and it has today shown off its full suite in action through what it describes as the world’s “first fully autonomous flight” of its type. read more

New “Unlimited” Underwater Air Supply

Fill your breathing tank by basic swimming motions

ExoLung

There’s a lot of ground between puttering around with your face strapped to a snorkel and managing the dangers, equipment, certification and expenses of scuba diving. Surface-supplied diving systems fill some of this space by strapping you to a breathing hose that plunges deeper than a snorkel but without some of the complications of scuba. Typically these systems rely on some form of compressed air, but a new prototype from Austria uses a more sustainable air supply: you. The ExoLung translates the diver’s swimming motions into air movement, keeping breathing air flowing so long as the diver keeps swimming.

Like other surface-supplied diving systems, the ExoLung has a buoy that floats on the surface of the water, serving both as a safety restraint and air intake. A hose connects the buoy with the water bell worn on the front of the torso. Inside the bell’s hardshell body, a collapsible water bladder is attached to leg straps that secure around the diver’s feet.

As the diver extends his or her legs, the straps pull the bladder, sucking in air as water is pushed out. Upon leg compression, the straps relax and water pressure fills the bladder back into the hardshell body, compressing the air for inhalation.

Other surface-supplied and portable breathing hardware that fills the gap between snorkelling and scuba diving is limited by the constraints of battery power or compressed air tanks. The Indiegogo-funded AirBuddy system advertises up to 45 minutes of lithium battery power, while the cylinder-supplied Scorkl breathing mask that hit crowdfunding around the same time in 2017 offers only 10 minutes.

Although Tasers are an effective alternative to the use of lethal force by police officers, getting shot by one is still quite a painful and potentially harmful experience. That’s where the BolaWrap 100 comes in – when fired at a “difficult” suspect, it simply ties them up. read more
