Researchers Show Influence of Nanoparticles on Nutrient Absorption
Researchers Show Influence of Nanoparticles on Nutrient Absorption
Mar 09, 2012 09:00 AM E
Nanoparticles are everywhere. From cosmetics and clothes, to soda and snacks. But as versatile as they are, nanoparticles also have a downside, say researchers at Binghamton University and Cornell University in a recent paper published in the journal Nature Nanotechnology. These tiny particles, even in low doses, could have a big impact on our long-term health.

2 for 1: Simultaneous Size and Electrochemical Measurement of Nanomaterials
Mar 08, 2012 16:07 PM E
Researchers at the National Institute of Standards and Technology (NIST) have done a mash-up of two very different experimental techniques-neutron scattering and electrochemical measurements-to enable them to observe structural changes in nanoparticles as they undergo an important type of chemical reaction.
Searching for Transforming Neutrinos
Experiment Observes Elusive Neutrino Transformation
Mar 08, 2012 16:01 PM E
An international team of physicists-including several from the California Institute of Technology (Caltech)-has detected and measured, for the first time, a transformation of one particular type of neutrino into another type. The finding, physicists say, may help solve some of the biggest mysteries about the universe, such as why the universe conta...

Ultrafast Sonograms Shed New Light on Rapid Phase Transitions
Mar 08, 2012 14:01 PM E
An international team of physicists has developed a method for taking ultrafast 'sonograms' that can track the structural changes that take place within solid materials in trillionth-of-a-second intervals as they go through an important physical process called a phase transition.

Long-delayed effort by EIA will quantify a decade of energy efficiency gains and focus decision-makers around higher standards. By Maria Gallucci, InsideClimate News The recent explosion of efficiency efforts across the country has slashed energy use in U.S. buildings, but by how much, exactly? After fits and starts, a federal statistics agency is finally poised to begin finding out.
Researchers Capture First-Ever Images Of Atoms Moving In A Molecule
Researchers Capture First-ever Images of Atoms Moving in a Molecule
Mar 08, 2012 11:39 AM E
Using a new ultrafast camera, researchers have recorded the first real-time image of two atoms vibrating in a molecule. Key to the experiment, which appears in this week's issue of the journal Nature, is the researchers' use of the energy of a molecule's own electron as a kind of "flash bulb" to illuminate the molecular motion.

Proposed Nuclear Clock may Keep Time with the Universe
Mar 08, 2012 11:22 AM E
A proposed new time-keeping system tied to the orbiting of a neutron around an atomic nucleus could have such unprecedented accuracy that it neither gains nor loses 1/20th of a second in 14 billion years - the age of the Universe.

Discovery of a New Kind of Neutrino Transformation
Mar 08, 2012 10:17 AM E
The Daya Bay Reactor Neutrino Experiment, a multinational collaboration operating in the south of China, today reported the first results of its search for the last, most elusive piece of a long-standing puzzle: how is it that neutrinos can appear to vanish as they travel? The surprising answer opens a gateway to a new understanding of fundamental ...

Elusive Higgs Boson in Sight?
Mar 07, 2012 16:46 PM E
After 40 years of searching, physicists have the elusive Higgs boson in their sights. Wade Fisher, Michigan State University assistant professor of physics, presented the team's results today at a physics conference in La Thuile, Italy.

Nanotrees Harvest the Sun's Energy to Turn Water into Hydrogen Fuel
Mar 07, 2012 15:19 PM E
University of California, San Diego 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. Reporting in the journal Nanoscale, the team said nanowires, which are made from abundant natural materials like silicon and zinc oxide...
Antimatter Trapped
The First Spectroscopic Measurement of an Anti-atom
Mar 07, 2012 14:18 PM E
The ALPHA collaboration at CERN in Geneva has scored another coup on the antimatter front by performing the first-ever spectroscopic measurements of the internal state of the antihydrogen atom. Their results are reported in a forthcoming issue of Nature and are now online. Ordinary hydrogen atoms are the most plentiful in the universe, and also ...

Was Einstein Wrong - or was the Cable Loose?
Mar 07, 2012 08:34 AM E
The world of science was upended last year when an experiment appeared to show one of Einstein's fundamental theories was wrong - but now the lab behind it says the result could have been caused by a loose cable.

Scientists at U.S. Lab Detect Hints of Elusive Particle
Mar 07, 2012 08:20 AM E
Scientists said they have gotten even closer to proving the existence of the elusive Higgs boson, the so-called "God particle" that supplies mass to matter and would complete Albert Einstein's theory of the universe.
