Experiment provides indications of an extragalactic component of cosmic rays
It is obvious from the data of the KASCADE-Grande experiment at the Karlsruhe Institute of Technology (KIT) that the so-called "knee" of the cosmic rays, a bend in the energy spectrum at high energies, is ...
Power-generating knee strap hints at end for batteries
Battery-powered devices could soon be a thing of the past thanks to a group of UK researchers who have created a novel energy harvester to power some of the latest wearable gadgets.
Gravity-beating ultrasonic tweezers provide a sound route to bio-engineering
Pioneering 'tweezers' that use ultrasound beams to grip and manipulate tiny clusters of cells under electronic, push-button control could lead to life-changing medical advances, such as better cartilage implants ...
New coating for hip implants could prevent premature failure
Every year, more than a million Americans receive an artificial hip or knee prosthesis. Such implants are designed to last many years, but in about 17 percent of patients who receive a total joint replacement, ...
On the horizon: Implants with built-in sensors that can shake off infection?
(Phys.org) —Keat Ghee Ong envisions a new generation of implantable biosensors. Not only could they signal if all is well (or not) after surgery, they would do it with no batteries and no computer chips. ...
A smart prosthetic knee with in-vivo diagnoses
The task was to develop intelligent prosthetic joints that, via sensors, are capable of detecting early failure long before a patient suffers. EPFL researchers have taken up the challenge.
Germany-based Turk takes knee-strain out of praying
A Turkish man living in Germany has invented a Muslim prayer mat that takes the strain off the knees which, he said Friday, he hoped to now sell worldwide.
Rare white tiger has knee surgery in Japan
