One bit of digital information stored on a hard disk currently consists of about 3 million magnetic atoms. Researchers from Karlsruhe, Strasbourg, and Japan have now developed a magnetic memory with one bit per molecule. By an electric pulse, the metal-organic molecule can be switched reliably between a conductive, magnetic state and a low-conductive, non-magnetic state. This novel correlation for molecules is now reported in the Nature Communications journal. (doi: 10.1038/ncomms1940)...

Scientists Take Picture Of Atom's Shadow
2012-07-04 04:52:53

Lee Rannals for redOrbit.com - Your Universe Online The art of microphotography just got a little smaller this week, as researchers announced they were able to snap a photo of a single atom for the first time. A Griffith University research team reported in the journal Nature Communications that they were able to successfully take a picture of the image. "We have reached the extreme limit of microscopy; you can not see anything smaller than an atom using visible light," Professor...

Scientists Make Strides Toward Quantum Computing
2012-07-04 04:33:58

Lee Rannals for redOrbit.com - Your Universe Online Harvard scientists claim that they have solved a problem faced in quantum computing by using diamonds. One challenge quantum computing has faced is creating quantum bits that exist in a solid-state system at room temperature. Most systems rely on complex and expensive equipment designed to trap an atom or electron in a vacuum, and then cool the entire system to nearly absolute zero, or –459.67° Fahrenheit. The Harvard team...

A Kansas State University-led quantum mechanics study has discovered a new bound state in atoms that may help scientists better understand matter and its composition. The yet-unnamed bound state, which the physicists simply refer to as "our state" in their study, applies to three identical atoms loosely bound together -- a behavior called three-body bound states in quantum mechanics. In this state, three atoms can stick together in a group but two cannot. Additionally, in some cases, the...

Google I/O Conference, Chrome, iOS
2012-06-29 05:07:30

Michael Harper for redOrbit.com — Your Universe Online Google´s very own developer conference, Google I/O, runs through the end of the week as the internet search team continues to give us something to talk about. On Thursday they announced the long-awaited iOS version of their popular Chrome browser, marking yet another alternative to the native mobile Safari browser. They also introduced an iOS-friendly version of their Google Drive online storage service, reports Laura...

Mapping The Nuclear Landscape
2012-06-28 04:15:29

An Oak Ridge National Laboratory and University of Tennessee team has used the Department of Energy's Jaguar supercomputer to calculate the number of isotopes allowed by the laws of physics. The team, led by Witek Nazarewicz, used a quantum approach known as density functional theory, applying it independently to six leading models of the nuclear interaction to determine that there are about 7,000 possible combinations of protons and neutrons allowed in bound nuclei with up to 120 protons (a...

Key experiment in nuclear physics Stable tin, as we know it, comprises 112 nuclear particles — 50 protons and 632 neutrons. The neutrons act as a kind of buffer between the electrically repelling protons and prevent normal tin from decaying. According to the shell model of nuclear physics, 50 is a "magic number" that gives rise to special properties. Tin-100, with 50 protons and 50 neutrons, is "doubly magic," making it particularly interesting for nuclear physicists. Shooting...

A team of chemists at the University of Geneva have finally demonstrated the utility of the rare halogen bond which acts as a anions transporter Professor Stefan Matile does not mention whether, as a child, he was a big fan of Lego. However, as an adult, he is fascinated by the game of molecular construction. Using the rules of chemistry, it is possible to artificially assemble all kinds of molecules and even nanomachines. However, chemists in this area feel their creativity constrained...

Black Holes Could Help Detect Hypothetical Particle
2012-06-19 05:48:11

Lee Rannals for redOrbit.com Scientists have determined that previously undetected particles could be seen as they accumulate around black holes. Vienna University of Technology scientists have discovered a method to prove the existence of hypothetical "axions," which are particles with a very low mass. “The existence of axions is not proven, but it is considered to be quite likely”, Daniel Grumiller, a researcher on the project, said in a press release. Grumiller,...

Ongoing saga of building a better fuel cell catalyst goes holistic The design of a nature-inspired material that can make energy-storing hydrogen gas has gone holistic. Usually, tweaking the design of this particular catalyst -- a work in progress for cheaper, better fuel cells -- results in either faster or more energy efficient production but not both. Now, researchers have found a condition that creates hydrogen faster without a loss in efficiency. And, holistically, it requires the...
