New Material Steals and Stores Oxygen from Air

Researchers from the University of Southern Denmark have synthesized crystalline materials that can bind and store oxygen in high concentrations.The stored oxygen can be released again when and where it is needed.

Depending on the atmospheric oxygen content, temperature, or pressure, it takes...

'Cloaking' Device Uses Ordinary Lenses to Hide Objects

Inspired perhaps by Harry Potter’s invisibility cloak, scientists have recently developed several ways to hide objects from view. The latest effort, begun at the University of Rochester, not only overcomes some of the limitations of previous devices, but also uses inexpensive, readily...

Motion Analysis Detects Joint Degeneration

If joints do no longer work as usual, humans tend to compensate this by unconsciously adapting their motions. In the case of knee arthrosis, or excessive joint wear, they shift the weight to the healthy leg. This relieves the worn knee joint, but also delays the pain that would indicate the start of...

HeartBeatID – Heart Electrical Actions as Biometric Indicia

One or more biometric indicia, such as fingerprints, voice prints, retinal scans, and facial features, are often used to identify or authenticate the identity of a user seeking access to a given resource. Cardiac muscle is myogenic and is capable of generating an action potential and...

Cryogenic Grinding for Mechanical Abrasion for Hardy Endospores

A comparative analysis was carried out between an emerging cryogenic grinding method and a conventional wet-chemistry/bead-beating endospore disruption approach. After extensive trial and error, it was determined that a regimen of three cryogenic grinding cycles of 2 minutes each...

Prosthetic Arm Controlled by Imagining a Motion

Controlling a prosthetic arm by just imagining a motion may be possible through the work of Mexican scientists at the Centre for Research and Advanced Studies. First, it is necessary to know if there is a memory pattern in the amputee's brain in order to know how the arm moved. The pattern is then...

Secret of Eumelanin’s Ability to Absorb Broad Spectrum of Light Uncovered

Melanin — and specifically, the form called eumelanin — is the primary pigment that gives humans the coloring of their skin, hair, and eyes. It protects the body from the hazards of ultraviolet and other radiation that can damage cells and lead to skin cancer. But...

'Active' Surfaces Control How Particles Move

Researchers at MIT and in Saudi Arabia have developed a new way of making surfaces that can actively control how fluids or particles move across them. The work might enable new kinds of biomedical or microfluidic devices, or solar panels that could automatically clean themselves of dust and...

Prediction of Visual Acuity from Wavefront Aberrations

Visual acuity (clearness of vision) usually is measured by an eye doctor using an eye chart. It measures the smallest letters that can be reliably identified by the patient at a specified distance. The traditional test requires the patient to look and report which letters they see.
