Vapotherm, a privately held manufacturer of respiratory care devices for hospital and home use, announced today that its Precision Flow® system has been validated by Ikaria, Inc. and cleared by the FDA for the administration of nitric oxide via high flow nasal cannula. The product is part of Vapotherm's High Flow Specialty Gas Program for optimal conditioning of breathing gases.

3D-Metal Forming of Holland can manufacture complex aircraft components, like a cockpit fuselage, but recently demonstrated their explosive forming technology in a successful R&D-project for Airbus. The technology was developed to manufacture components for fusion reactors.
Social welfare is an unconvincing argument to most - you what you pay for is a time-honored fact. But sometimes a product is the same whether you pay a lot or a little. Or nothing at all.
A forthcoming paper in Marketing Science identifies the social-welfare benefits of open source software, despite the existence of free-riding.
In the first moments after a mining accident, first responders work against the clock to assess the situation and save the miners. But countless dangers lurk: poisonous gases, flooded tunnels, explosive vapors and unstable walls and roofs. Such potentially deadly conditions and unknown obstacles can slow rescue efforts to a frustrating pace.
To speed rescue efforts, engineers at Sandia National Laboratories have developed a robot that would eliminate some of the unknowns of mine rescue operations and arm first responders with the most valuable tool: information.
Tiny particles made of polymers hold great promise for targeted delivery of drugs and as structural scaffolds for building artificial tissues. However, current production methods for such microparticles yield a limited array of shapes and can only be made with certain materials, restricting their usefulness.
Robotics Trends, a division of EH Publishing, today unveiled robonexus.com, a new website designed to serve people interested in robots and robotics technologies and want to learn about them.
Decades after the bullets have stopped flying, wars can leave behind a lingering danger: land mines that harm civilians and render land unusable for agriculture. Left over minefields are a danger throughout the world but now researchers in Scotland have designed a new device that could more reliably sense explosives, helping workers to identify and deactivate unexploded mines.
Optical cloaking devices that enable light to gracefully slip around a solid object were once strictly in the realm of science fiction. Today they have emerged as an exciting area of study, at least on microscopic scales. A new twist on this technology can now be "seen" in the field of acoustics.
A team of researchers from the Universitat Politecnica de Valencia and the Universidad de Valencia have created a prototype of an acoustic cloak by using a 2-D mathematical model.
A new computer model that describes the evolution of the Internet's architecture suggests that a process similar to natural evolution took place to determine which protocols survived and which ones became extinct. Understanding the evolution may help the designers of future Internet architectures - as long as you believe you can guide evolution, that is.
Risø DTU has made its eighth report in the series: 'Nuclear power and Nuclear Safety', which gives a global overview of nuclear energy with a focus on safety and preparedness. This year's report is a bit delayed because of the accident in Fukushima, which is also mentioned in the report that would normally cover only the year 2010.
The change in energy policy has been decided; Germany needs more green energy. From Sep. 5-9 in Hamburg, everything will revolve around our biggest energy supplier: the sun. At the European Photovoltaic Solar Energy Conference, in Hall B4G, Stand C12, Fraunhofer researchers will present new methods for making solar cells cheaper and more efficient.
Two Lehigh physicists have developed an imaging technique that makes it possible to directly observe light-emitting excitons as they diffuse in a new material that is being explored for its extraordinary electronic properties. Called rubrene, it is one of a new generation of single-crystal organic semiconductors.
One of the earliest lessons in science that students learn is that a ray or beam of light travels in a straight line. Students also learn that light rays fan out or diffract as they travel. Recently it was discovered that light rays can travel without diffraction in a curved arc in free space. These rays of light were dubbed “Airy beams,” after the English astronomer Sir George Biddell Airy, who studied what appears to be the parabolic trajectory of light in a rainbow.
MINNEAPOLIS / ST. PAUL (08/11/2011) —Computer science researchers in the University of Minnesota’s College of Science and Engineering are leading a team that has confirmed a substantial gender gap among editors of Wikipedia and a corresponding gender-oriented disparity in the content. The team’s research will be presented at the 2011 WikiSym conference, the seventh annual International Symposium on Wikis and Open Collaboration, in California this fall.
Face recognition software of the kind incorporated into biometric identification tools, photo-gallery applications and social media websites can be very useful but the technology raises privacy concerns, given the seeming ease with which faces in photos can now be tied to an individual. Researchers in Russia and Poland hope to take face recognition technology an important step forward with the even more powerful software they have developed.
