Oxygent is an intravascular oxygen carrier ("blood substitute") designed to temporarily augment oxygen delivery in patients at risk of acute tissue oxygen deficit due to either transient anemia, blood loss, or ischemia (inadequate oxygenation resulting from blood flow abnormalities). Oxygent is compatible with all blood types, has a shelf-life of up to two years, is sterilized, and is produced in Alliance's commercial-scale manufacturing facility using an economical, efficient, proprietary process. Phase 3 clinical (human) studies have been completed in Europe and are ongoing in the U.S. [ more | discuss ]

Lightweight optoelectronic systems built around advanced image sensors and display panels have been proposed for making selected objects appear nearly transparent and thus effectively invisible. These systems are denoted "adaptive camouflage" because unlike traditional camouflage, they would generate displays that would change in response to changing scenes and lighting conditions.

Despite recent advances, most of the existing rapid prototyping processes are quite expensive and many of them generate substances such as smoke, dust, hazardous chemicals, etc., which are harmful to human health and the environment.

Researchers at the University of Missouri-Rolla have developed an experimental rapid freeze prototyping system for building three-dimensional parts out of ice. [ more | discuss ]

The Foresight Institute, a nonprofit educational organization formed to help prepare society for anticipated advanced technologies, primarily focused on nanotechnology, has joined the weblog revolution. [ more | discuss ]

The ThinkQuest Internet Challenge is an international program for students ages 12 through 19 that encourages them to use the Internet to create information-rich Web-based educational tools and materials. Students form teams with their colleagues from around the world and are mentored by teachers or other adult coaches. [ more | discuss ]

Living systems can be used to produce microscopically small components of uniform size that potentially can be used to build electronic devices, according to researchers at The University of Texas at Austin.

"Viruses were chosen by whatever material they naturally 'stuck' to the best and, consequently, only tend to 'stick' to that particular material. We used evolutionary tools to select proteins that can control these technologically important materials, with the goal of building next-generation devices" [ more | discuss ]

The chief obstacle to superconducting electronics has been the lack of a 3-terminal device which can switch and amplify current. Now, Norman Booth of Oxford and Antonio Barone of the University of Naples and their colleagues have overcome this problem. [ more | discuss ]

COLOUR displays that can be made using a simple "printing" process will provide ultra-cheap video screens for the next generation of cellphones and palmtops, say British researchers.

A polymer called PPV will emit light when a voltage is applied to them. Because PPV molecules contain benzene rings, which allow electrons to move through the molecule, the polymer can act as a semiconductor--and form the basis of a light-emitting diode. [ more | discuss ]

A list of mathematical mistakes made over and over by advertisers, the media, reporters, politicians, activists, and in general many non-math people. These come from many sources, which will appear in parenthesis. Paul Cox makes an attempt try to find an actual example of each type of mistake for learning purposes. [ more | discuss ]

A new breed of photonic switches—of which at least a dozen are on the way to market— skip the step of converting light into electrons to switch the beams, and, unlike electronics, all-optical devices can deftly redirect even the most complex light streams. All the approaches being tried rely on shrinking the switch components. But after that, it’s a technology free-for-all. [ more ]
