The controlled organization of inorganic materials into multi-dimensional addressable arrays is the foundation for logic and memory devices, as well as other nonlinear optical and sensing devices. Many of these devices are currently fabricated using...

A concept for a unique zero-g condensing heat exchanger that has an integral ozone-generating capacity has been conceived. This design will contribute to the control of metabolic water vapor in the air, and also provide disinfection of the resultant condensate, and the disinfection of the...

A life support system generates oxygen in low oxygen and/or hazardous environments such as mining, chemical/biological attacks, nuclear fallout, or space exploration. Based on proven technology, this O2/CO2 control system has the potential to significantly reduce the mass of the...

Monitoring colon health and transformation into a diseased tissue, including inflammation and cancer, is difficult using conventional techniques, as individuals are required to undergo invasive procedures. However, by using exfoliated cells, it is...

Stanford Biodesign fellows are testing two tiny devices that stimulate natural tear production. The technologies deliver micro-electrical pulses to the lacrimal gland.

Touch feedback, known as haptics, has been used in entertainment, rehabilitation, and even surgical training. University of Bristol researchers, using ultrasound, have developed an invisible 3D haptic shape that can be seen and felt.Led by Dr Ben Long and colleagues Professor Sriram Subramanian, Sue Ann Seah, and...

When a person is interviewed, some of the answers may be inaccurate, or even deceptive, because the person may have either incomplete information, is telling only part of the truth, or is fabricating a false answer, or a combination of all three. When the person is habitually making...

Knowledge of a patient’s cardiac age, or “heart age,” could prove useful to both patients and physicians for encouraging lifestyle changes that are potentially beneficial for cardiovascular health. This may be particularly true for patients who exhibit symptoms, but who test negative for cardiac...

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.

Researchers at the University of Granada have designed a new imaging system capable of obtaining up to twelve times more color information than the human eye and conventional cameras, which implies a total of 36 color channels. The important scientific development will facilitate the easy...

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 seconds,...

New York, NY – Contour Crafting, a computerized construction method that rapidly 3D prints large-scale structures directly from architectural CAD models, has been awarded the grand prize of $20,000 in the 2014 "Create the Future" Design Contest. Contour Crafting...

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...

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...

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 was...
