Neck band made to protect the brain

When we think about avoiding concussions, we tend to think of helmets. The problem is, concussions are typically caused by the brain suddenly "sloshing" within the skull, knocking itself against the inside of the cranium. Helmets help reduce the likelihood of that happening by absorbing impact energy, but they're not 100 percent effective – that's why concussions can sometimes occur even without a hit being delivered directly to the head. Help may be on the way, however, in the form of a simple neck band.Read More

Liquid metal runs through new flexible circuits

Before things like touch-sensitive robot skin or prosthetics skin can become commonplace, we first need to develop robust and reliable flexible electronics. Researchers from Switzerland's EPFL research institute have taken a big step toward that goal, by developing circuits that remain functioning while being stretched by up to four times their original length.Read More

Telescoping bike changes shape to fit the rider

While getting a bicycle hand-built to your exact dimensions can indeed ensure a custom fit, it can also be quite expensive, plus that bike will be made mainly with one type of riding in mind. That's part of the reason that UK frame-builder Mike Hickman created the Hickman Bike. The idea behind it is that using an "off-the-rack" bike, riders will still be able to get that exact fit, and will also be able to adapt it for different types of riding.Read More

A really big bike for vertically-gifted riders

If you're an exceptionally tall cyclist, then you'll know that finding a bicycle that fits can be quite the challenge. Some manufacturers place a sort of teetering high-rise frame on regular wheels, but according to Santa Cruz-based frame builder David Folch, that setup doesn't result in proper handling or ergonomics. That's why he's created the ginormous DirtySixer.Read More

3D-printed titanium offers new possibilities for bike builders

Road bikes made from a mix of titanium and carbon fiber are already pretty special, and even more so if they're made to order. The folks at Australia's Bastion Cycles, however, are taking things even further. Their recently-announced first model features filament-wound carbon tubes, joined to one another with titanium lugs that are 3D printed to fit the buyer.Read More

Bicycle sports its own full weather station

We've already seen bikes that double as a talk show set, coffee shop and pizza-serving bar, but a full-size weather-monitoring station? That's a new one. It's also exactly what University at Buffalo architect Nicholas Rajkovich created, however, to collect fine-scale weather data around Cleveland and area. Over 50 lb (23 kg) of gear was added to an existing touring bike, which Prof. Rajkovisch rode throughout the city over the course of a summer.Read More

Electronic system takes the guesswork out of respiratory diagnoses

Listening to a patients' breathing is certainly a key part of diagnosing their respiratory problems. However, doctors' individual observer bias certainly comes into play, plus it can be difficult to make a diagnosis when there's a lot of background noise. That's why scientists at Hiroshima University have created an electronic system that objectively matches lung sounds to specific maladies.Read More
