Front-wheel-drive KerVelo bike eliminates the chain

Recumbent bicycles may offer a more comfortable riding position, but they typically also have pretty long chains. After all, power has to be transmitted from the pedals at the front to the drive wheel at the back. Norway-based inventor Marc Le Borgne, however, has created an alternative. His KerVelo recumbent has an 18-speed gearhub transmission built into the front wheel.Read More

A-Gear exoskeletons keep users' arms useful

Affecting approximately 1 in 5,000 boys, Duchenne muscular dystrophy causes the victim's muscles to shrink throughout their lifetime, often to the point that the arms and legs can't be used at all. That's why the european Stichting Flextension (Flextension Foundation) started up the A-Gear project four years ago. The multi-partner effort is designing two arm-worn exoskeletons, intended to help Duchenne patients retain the use of their arms.Read More

NutriRay3D uses laser light and your phone to count calories

There are already plenty of apps that let people estimate how many calories are in the foods they're eating. However, most of these programs require users to either guess at their portion sizes, or actually weigh the food. That's where the University of Washington's NutriRay3D comes in. It's a smartphone device/app combo, that uses lasers to ascertain how many calories are sitting on the plate.Read More

FAROS drone climbs the walls to find fires

Fires in high-rises can be particularly deadly. This is partially because of the buildings' "chimney" effect, along with the fact that it's just plain difficult for firefighters to reach the flames. With that in mind, researchers at the Korea Advanced Institute of Science and Technology (KAIST) have created the flying, wall-climbing, fire-resistant FAROS quadcopter. It's designed to ascertain the source of a fire as soon as possible, along with the locations of people trapped within the building. Read More

MRIs could soon be quicker and safer

While MRI scans may not expose patients to the ionizing radiation found in X-rays, they still are potentially harmful. This is because the increased radiofrequency energy absorption associated with newer high-field and ultra-high-field MRI scanners can heat body tissue. Thanks to research being conducted at the Australian National University, however, that may soon no longer be an issue – additionally, scans could be quicker and produce higher-quality images.Read More

Painless electrical zaps may replace dental anesthesia needles

As much as some people fear getting dental fillings or root canals, what many of them are really afraid of is the needle that delivers the anesthetic into the mouth tissue. Even though the skin in the "jabbing area" is usually pretreated with a topical anesthetic, it can still hurt. Before long, however, a shot of electricity could make that topical treatment deep-acting enough that the needle isn't even needed.Read More
