NASA sees second biggest flare of the solar cycle

Posted: 07 Mar 2012 03:51 PM PST

The leading edge of the first of two major coronal mass ejections will reach Earth at about 1:25 AM EST on the morning of March 8 (plus or minus 7 hours). Such a CME could result in a severe geomagnetic storm, causing aurora at low latitudes, with possible disruption to high frequency radio communication, global positioning systems (GPS), and power grids.

Communication technologies including smartphones and laptops could now be 1,000 times faster, new study suggests

Posted: 07 Mar 2012 01:28 PM PST

Many of the communication tools of today rely on the function of light or, more specifically, on applying information to a light wave. Thanks to research, a physical basis for terahertz bandwidth (THz, or 1 trillion cycles per second) -- the portion of the electromagnetic spectrum between infrared and microwave light -- has now been demonstrated.

First spectroscopic measurement of an anti-atom

Posted: 07 Mar 2012 11:54 AM PST

Scientists have captured and held atoms of antihydrogen, a single antiproton orbited by a single positron. Now, by measuring antihydrogen's hyperfine structure, they have achieved another first in antimatter science with the very first measurements of the energy spectrum of an anti-atom.

Researchers capture first-ever image of two atoms forming a molecule

Posted: 07 Mar 2012 10:22 AM PST

Using a new ultrafast camera, researchers have recorded the first real-time image of two atoms vibrating in a molecule. Key to the experiment is the researchers' use of the energy of a molecule's own electron as a kind of "flash bulb" to illuminate the molecular motion.

Players get more pleasure from motion-based video games

Posted: 07 Mar 2012 10:20 AM PST

The newest motion-based video games — which are more interactive than standard video game systems with gamepads — are more realistic, give a greater sense of "being there" and are more enjoyable, according to findings by communications studies researchers.

Nanomanufacturing using DNA origami

Posted: 07 Mar 2012 08:27 AM PST

In recent years, scientists have begun to harness DNA's powerful molecular machinery to build artificial structures at the nanoscale using the natural ability of pairs of DNA molecules to assemble into complex structures. While most researchers of "DNA origami" are working to demonstrate what's possible, scientists are now seeking to determine what's practical.

'Star comb' to aid quest for Earth-like planets

Posted: 07 Mar 2012 08:27 AM PST

If there is life on other planets, a laser frequency comb may help find it. Such a comb -- a tool for precisely measuring frequencies, or colors, of light -- has for the first time been used to calibrate measurements of starlight from stars other than the Sun. The good results suggest combs will eventually fulfill their potential to boost the search for Earth-like planets to a new level.

Market exchange rules responsible for wealth concentration, physicists say

Posted: 07 Mar 2012 08:26 AM PST

Physicists have shown that wealth concentration invariably stems from a particular type of market exchange rules -- where agents cannot receive more income than their own capital. The authors concluded that maximum inequalities ensue from free markets, which are governed by such seemingly fair rules.

Oxide thin films to create new field of oxide electronics

Posted: 07 Mar 2012 08:24 AM PST

Researchers have developed the first functional oxide thin films that can be used efficiently in electronics, making new high-power devices and sensors possible. This is the first time researchers have been able to produce positively-charged and negatively-charged conduction in a single oxide material, launching a new era in oxide electronics.

Nanotrees harvest the sun's energy to turn water into hydrogen fuel

Posted: 07 Mar 2012 08:23 AM PST

Electrical engineers are building a forest of tiny nanowire trees in order to cleanly capture solar energy without using fossil fuels and harvest it for hydrogen fuel generation. The team said nanowires, which are made from abundant natural materials like silicon and zinc oxide, also offer a cheap way to deliver hydrogen fuel on a mass scale.

Galaxies get up close and personal: Collisions in young galaxy cluster

Posted: 07 Mar 2012 06:44 AM PST

The VLT Survey Telescope (VST) at the European Southern Observatory's Paranal Observatory in Chile has imaged a fascinating collection of interacting galaxies in the Hercules galaxy cluster. The sharpness of the new picture, and the hundreds of galaxies captured in great detail in less than three hours of observations, attest to the great power of the VST and its huge camera OmegaCAM to explore the nearby Universe.

Cloud computing: The trustworthy cloud

Posted: 07 Mar 2012 06:43 AM PST

Not a week goes by without reports on security gaps, data theft or hacker attacks. Both businesses and private users are becoming increasingly uneasy. However, when it comes to technologies like cloud computing, trust and security are essential if we intend to use data and applications that are flexible, cost-effective and above all, mobile.

Elusive Higgs boson may nearly be cornered

Posted: 07 Mar 2012 05:36 AM PST

New measurements announced by scientists from the CDF and DZero collaborations at the U.S. Department of Energy's Fermi National Accelerator Laboratory indicate that the elusive Higgs boson may nearly be cornered. After analyzing the full data set from the Tevatron accelerator, which completed its last run in September 2011, the two independent experiments see hints of a Higgs boson.
