Lithium in the brain Experiments with neutrons at the Technische Universität München (TUM) show that the antidepressant lithium accumulates more strongly in white matter of the brain than in grey matter. This leads to the conclusion that it works differently from synthetic psychotropic drugs. The tissue samples were examined at the Research Neutron Source Heinz Maier-Leibnitz (FRM II) with the aim of developing a better understanding of the effects this substance has on the human psyche....

The Largest Magnetic Fields In The Universe

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Gamma-ray bursts (GRBs) are thought to be the most powerful, energetic events in the Universe. They can release as much energy in one second as an entire galaxy expels in an entire year. But while astronomers have some solid theories on what drives these events, many of the details are still widely debated. One of the complicating matters comes from the fact GRBs appear to fall into two separate classes: long and short burst...

Evidence Of New Phase In Neutron Stars Discovered
2013-06-14 13:48:03

Lee Rannals for redOrbit.com — Your Universe Online University of Alicante researchers have discovered the first evidence of a new phase in neutron stars. The scientists wrote in the journal Nature Physics that they have detected what may be the first observational evidence of existence of a new exotic phase of matter in what is known as the "inner crust" of neutron stars, or pulsars. "This may be the first observational evidence of existence of the phase of nuclear...

H2O Reveals New Secret

Carnegie Institution Using revolutionary new techniques, a team led by Carnegie's Malcolm Guthrie has made a striking discovery about how ice behaves under pressure, changing ideas that date back almost 50 years. Their findings could alter our understanding of how the water molecule responds to conditions found deep within planets and could have implications for energy science. Their work is published in the Proceedings of the National Academy of Sciences. When water freezes into ice,...

WASHINGTON, May 29, 2013 /PRNewswire-USNewswire/ -- Astronomers using NASA's Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, yielding clues they can use to understand these extremely dense objects. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) A neutron star is the crushed core of a massive star that ran out of fuel, collapsed under its own weight, and exploded as a supernova. A neutron star can spin as fast as 43,000 times per minute and...

NASA X-Ray Observatory Reveals Magnetars More Common Than Thought
2013-05-24 14:42:15

Lee Rannals for redOrbit.com — Your Universe Online NASA's Chandra X-ray Observatory has revealed that some of the most extreme objects in the universe may be more common than previously thought. Magnetars are the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation. When a massive star runs out of fuel its core collapses to form a neutron star. Most neutron stars spin rapidly, but a small fraction have a relatively low spin rate while also...

Dark Lightning And Visible Lightning May Be Connected

Watch the video "Scientists Detect Dark Lightning Linked To Visible Lightning" Brett Smith for redOrbit.com - Your Universe Online Discovered in 1991, dark lightning is an electrical phenomenon that occurs deep within a thunderhead and is responsible for producing a powerful burst of radio waves and gamma rays. Now, new research from an international team of scientists has found that dark lightning and visible lightning may be connected, according to a report in Geophysical...

A research team from Birkbeck, University of London, Royal Holloway University and Uppsala University in Sweden, have helped explain how ozone causes severe respiratory problems and thousands of cases of premature death each year by attacking the fatty lining of our lungs. In a study published in Langmuir, the team used neutrons from the Institut Laue-Langevin in Grenoble and the UK's ISIS Neutron Source to observe how even a relatively low dose of ozone attacks lipid molecules that line...

To increase the neutron detection efficiency of Bulk-Micromegas (MICRO-MEsh GAseous Structure) neutron detectors, researchers from Lanzhou University (China), IRFU-CEA (France), and the University of Tennesse-Knoxville (USA) have proposed three novel converters. When validated using Monte Carlo simulations, the design results in a threefold increase in neutron detection efficiencies. This work is described in detail in SCI CHINA: Tech. Sci. 2013, 43(3). The team have now made a...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...
