vortex multiplication in a quantum fluid
2014-03-26 03:00:39

University of Cambridge Researchers have developed a new mathematical framework capable of describing motions in superfluids – low temperature fluids that exhibit classical as well as quantum behavior. The framework was used to lift the veil of mystery surrounding strange objects in superfluid helium (detected ten years ago at Brown University). The study, conducted by an international collaboration of researchers from the UK, Russia and France is published today in the journal...

A University of Maryland research team provides visual evidence confirming computer simulations of a special type of ripple that dissipates energy in extremely cold liquid helium. The research could lead to advances in superconductors. College Park, MD (PRWEB) March 24, 2014 Draining the water from a bathtub causes a spinning tornado to appear. The downward flow of water into the drain causes the water to rotate, and as the rotation speeds up, a vortex forms that obeys the laws of...

Oxygen’s Different Shapes Described By Researchers
2014-03-14 14:31:07

North Carolina State University Oxygen-16, one of the key elements of life on earth, is produced by a series of reactions inside of red giant stars. Now a team of physicists, including one from North Carolina State University, has revealed how the element’s nuclear shape changes depending on its state, even though other attributes such as spin and parity don’t appear to differ. Their findings may shed light on how oxygen is produced. Carbon and oxygen are formed when helium burns...

Gas giant Jupiter
2014-03-12 05:09:27

April Flowers for redOrbit.com - Your Universe Online An international team of researchers recently got a sneak peek deep into the lower atmospheric layers of gas giant planets such as Jupiter or Saturn using Deutsches Elektronen-Synchrotron's (DESY) X-ray laser FLASH. The team's observations, led by Dr. Ulf Zastrau of the University of Jena, demonstrate how liquid hydrogen becomes a plasma. The findings, published in Physical Review Letters, also provide information on the material's...

Two Sources Of Helium Produced By Ancient Yellowstone Activity

[ Watch the Video: Yellowstone Releasing Ancient Helium ] Lawrence LeBlond for redOrbit.com - Your Universe Online As one might expect, Yellowstone National Park’s hot springs, geysers and other hydrothermal vents release gases stored deep below the Earth, including carbon dioxide and methane. Another gas has also been discovered to be squeaking out of Yellowstone’s vents, and while it is a common gas released from volcanic rocks, in this region, most of it comes from a much...

Grand Canyon May Not Be As Old As Once Thought
2014-01-27 08:50:13

[ Watch the Video: How Old Is The Grand Canyon? ] Brett Smith for redOrbit.com - Your Universe Online Previous theories have pegged the age of the Grand Canyon at 70 million years ago, but a new study published by Nature Geoscience has found that the American icon was completely formed 5 to 6 million years ago when shorter segments of canyon united to form an expansive chasm. “I think we’ve resolved the 140-year-long debate about the age of the Grand Canyon,” Karl Karlstrom, a...

Helium-Filled Hard Drives Faster Cooler Bigger
2013-11-04 10:42:43

Michael Harper for redOrbit.com - Your Universe Online Last September, Hitachi Global Storage Technologies (HGST) announced that they planned to revolutionize hard drive storage by building hermetically-sealed disk drives filled with helium. The theory behind this change is that the lighter-than-air gas will create less friction as the plates of the drive spin and allow memory to be accessed more quickly. Today HGST, a subsidiary of Western Digital, is shipping the worlds-first...

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...
