STEVENSVILLE, Md., Oct. 27, 2011 /PRNewswire-USNewswire/ -- Vapotherm announced today receiving FDA clearance for Precision Flow® Heliox, a high flow humidification system designed specifically for use with blended helium oxygen gas mixtures (Heliox). The product is part of Vapotherm's High Flow Specialty Gas Program for optimal conditioning of breathing gases. Heliox is used in a variety of respiratory applications such as upper airway obstruction, asthma, croup and...

The Star That Should Not Exist

  A team of European astronomers has used ESO´s Very Large Telescope (VLT) to track down a star in the Milky Way that many thought was impossible. They discovered that this star is composed almost entirely of hydrogen and helium, with only remarkably small amounts of other chemical elements in it. This intriguing composition places it in the “forbidden zone” of a widely accepted theory of star formation, meaning that it should never have come into existence in the...

STEVENSVILLE, Md., Aug. 24, 2011 /PRNewswire-USNewswire/ -- Vapotherm, announced today receiving CE marking for Precision Flow® Heliox, a high flow humidification system designed specifically for use with blended helium oxygen gas mixtures (Heliox). The product is part of Vapotherm's High Flow Specialty Gas Program for optimal conditioning of breathing gases. Due to helium's lower density as compared to nitrogen, the primary gas in room air, breathing with heliox results...

LEHIGH VALLEY, Pa., Aug. 15, 2011 /PRNewswire/ -- Effective September 1, 2011, or as contracts permit, Air Products (NYSE: APD) will be implementing a price increase of 15 percent for liquid and bulk helium gases in North America. The pricing adjustment is the result of several factors including the continued strong demand over the past year for helium and significant reductions in supply. The helium market has been tight across the globe with product allocations implemented by the...

It has been 100 years since the discovery of superconductivity, a state achieved when mercury was cooled, with the help of liquid helium, to nearly the coldest temperature achievable to form a superfluid that provides no resistance to electrons as they flow through it. During that century, scientists have struggled to find a precise mathematical explanation of why and how this strange fluid behaves as it does. Liquid helium-4 itself becomes a superfluid when cooled to within a few degrees of...

Researchers at the University of Warwick have found a unique feuding double white dwarf star system where each star appears to have been stripped down to just its helium. We know of just over 50 close double white dwarfs but this was only the second ever eclipsing close white dwarf pair to be found. The University of Warwick astronomers Steven Parsons and Professor Tom Marsh were able to use the fact that the stars eclipse each other when seen from Earth to make particularly detailed...

Alternative explanation for exotic state of matter posited in new Science paper The long-held, but unproven idea that helium-4 enters into an exotic phase of matter dubbed a "supersolid" when cooled to extremely low temperatures has been challenged in a new paper published recently in Science. Los Alamos National Laboratory researchers Alexander Balatsky and Matthias Graf joined Cornell University physicist J.C. S©amus Davis and others in describing an alternative explanation for...

In a four-decade, Holy Grail-like quest to fully understand what it means to be in a "supersolid" state, physicists have found that supersolid isn't always super solid. In other words, this exotic state of frozen helium appears to have liquid-like properties, says a new paper published in the journal Science (May 13, 2011). Why is this important? Understanding supersolid helium brings us closer to understanding its close cousins superconductivity and superfluidity. Physicists had long thought...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
