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.
I guess “cheaper” is relative.
Mark Levinson offers audiophiles a cheaper high-end turntable
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.
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.
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.
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.
