Researchers at the Institute of Food Research have tested a new technique to ensure fresh produce is free of bacterial contamination. Plasmas are a mix of highly energetic particles created when gases are excited by an energy source. They can be used to destroy bacteria but as new research shows, some can hide from its effects in the microscopic surface structures of different foods. Eating fresh fruit and vegetables is promoted as part of a healthy lifestyle, and consumers are...

April Flowers for redOrbit.com - Your Universe Online Thermalization is the process of particles reaching thermal equilibrium through mutual interaction. We see this process around us every day. Take for example, ice cubes dropped into a pot of hot water. The cubes melt and cannot remain stable. Well-ordered ice crystals turn into a disordered liquid as the molecules of the ice and the molecules of the water reach thermal equilibrium, ending up at the same temperature. Research at the...

Researchers reproduce plasma loops to help understand solar physics In orbit around Earth is a wide range of satellites that we rely on for everything from television and radio feeds to GPS navigation. Although these spacecraft soar high above storms on Earth, they are still vulnerable to weather–only it's weather from the sun. Large solar flares–or plasma that erupts from the sun's surface–can cause widespread damage, both in space and on Earth, which is why researchers...

Researchers at a recent worldwide conference on fusion power have confirmed the surprising accuracy of a new model for predicting the size of a key barrier to fusion that a top scientist at the U.S. Department of Energy´s Princeton Plasma Physics Laboratory (PPPL) has developed. The model could serve as a starting point for overcoming the barrier. “This allows you to depict the size of the challenge so you can think through what needs to be done to overcome it,” said...

Magnetic Turbulence Could Cause Solar Wind Temperature Rise
2012-08-19 06:44:46

redOrbit Staff & Wire Reports - Your Universe Online Magnetic turbulence is most likely the reason that solar wind moving away from our sun and our solar system is hotter than it theoretically should be, according to new research from scientists at the University of Warwick. As solar wind leaves the sun and expands beyond the solar system, it should begin to cool off due to the lack of particle collisions to dissipate energy, the university explained in a Friday press release. That...

Extreme Plasma Theories Are Being Put To The Test
2012-08-07 13:20:41

The first controlled studies of extremely hot, dense matter have overthrown the widely accepted 50-year old model used to explain how ions influence each other's behavior in a dense plasma. The results should benefit a wide range of fields, from research aimed at tapping nuclear fusion as an energy source to understanding the inner workings of stars. The study also demonstrates the unique capabilities of the Linac Coherent Light Source (LCLS) X-ray laser at the U.S. Department of Energy...

Cluster Examines Thin Current Sheets In The Magnetosphere
2012-08-02 05:08:15

April Flowers for redOrbit.com - Your Universe Online The Universe is filled with plasma, a charged gas consisting of ions and electrons. Thin sheets, or boundaries, with currents separate large plasma regions. These boundaries are where most of the exciting action in space happens. Scientists at the Swedish Institute of Space Physics (IRF) have measured the fundamental properties of one of the waves mixing and accelerating plasmas within these sheets. These thin current sheets are...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Solar Prominence -- Solar prominences are large arch-shaped structures observable in the solar corona. These often have a twist and occasionally become unstable, ejecting plasma and magnetic flux out from the sun. The physics of solar prominence instability is believed to be governed by magnetic forces and magnetic helicity issues. It is thought that instability occurs when a magnetic flux tube becomes excessively twisted. ----- Click here to learn more on this topic from eLibrary:

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
