Researchers Reconfirm Original Tetrahedral Model Of Water Molecules
2013-02-13 04:45:42

Lee Rannals for redOrbit.com - Your Universe Online For all those who worried back in 2004 that the sky was falling because the original model of the molecular structure of water toppled out, have no fear, because things can go back to the way they used to be. Johannes Gutenberg University Mainz (JGU) researchers confirmed the original tetrahedral model, after an international research group challenged the model nine-years ago, claiming that water molecules form bonds only with two...

Quantum Smell May Exist
2013-01-28 19:48:08

Brett Smith for redOrbit.com — Your Universe Online The majority of the scientific community has embraced the idea of different smells being based on the olfactory receptors´ ability to detect various shapes of odor molecules. However, a new study in the open access journal PLOS ONE has given credence to a less popular theory; that the sense of smell is based on the molecules´ different vibrations, not their shapes. The idea of a quantum, or vibration, basis for...

Molecular Matter Is The Same As 7 Billion Years Ago
2012-12-13 14:29:50

Lee Rannals for redOrbit.com - Your Universe Online Researchers reported today in the journal Science Express that the ratio of the proton's mass to that of the electron has hardly changed over the past seven billion years. This fundamental constant of nature has changed by a maximum of one hundred thousandth of a percent over cosmic history. Scientists from VU University Amsterdam and the Max-Planck-Institut für Radioastronomie (MPIfR) used the Effelsberg 100-m radio...

What Sparked The Origin Of Life
2012-11-27 06:45:21

April Flowers for redOrbit.com - Your Universe Online Scientists have questioned how life began on a molecular level for a very long time. And now, an international team of researchers has presented evidence that sheds light on a possible mechanism by which life may have gotten a foothold in the chemical soup that existed early in the Earth's history. Several competing theories have been previously proposed for how life got its start even before the first genes or living cells emerged....

No Assembly Required - Microparticles That Self-assemble
2012-10-31 15:46:47

Harvard University Scientists have created new kinds of particles, 1/100th the diameter of a human hair, that spontaneously assemble themselves into structures resembling molecules made from atoms. These new particles come together, or "self-assemble," to form structures in patterns that were previously impossible to make and hold promise for manufacturing advanced optical materials and ceramics. The method, described in the latest issue of the journal Nature, was developed by a team of...

Molecular Bond Issue Forced
2012-09-06 09:18:06

New and Improved Model of Molecular Bonding from Researchers at Berkeley Lab´s Molecular Foundry Material properties and interactions are largely determined by the binding and unbinding of their constituent molecules, but the standard model used to interpret data on the formation and rupturing of molecular bonds suffers from inconsistencies. A collaboration of researchers led by a scientist at the U.S Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley...

New Device Can Weigh Molecules One At A Time
2012-08-27 09:40:58

Caltech-led physicists create first-ever mechanical device that measures the mass of a single molecule A team led by scientists at the California Institute of Technology (Caltech) have made the first-ever mechanical device that can measure the mass of individual molecules one at a time. This new technology, the researchers say, will eventually help doctors diagnose diseases, enable biologists to study viruses and probe the molecular machinery of cells, and even allow scientists to...

Scientists have discovered that a space inside a special type of carbon molecule can be used to imprison other smaller molecules such as hydrogen or water. The nano-meter sized cavity of the hollow spherical C60 Buckminsterfullerene – or bucky ball – effectively creates a 'nanolaboratory', allowing detailed study of the quantum mechanical principles that determine the motion of the caged molecule, including the mysterious wave-like behaviour that is a fundamental property of...

Study Properties Of Smallest Water Droplets Known
2012-08-16 10:48:49

Brett Smith for redOrbit.com - Your Universe Online Using computer modeling, researchers at the University of California, San Diego and Emory University have revealed new details surrounding hexamer structures that are considered to be the smallest droplets of water. "Ours are the first simulations that use an accurate, full-dimensional representation of the molecular interactions and exact inclusion of nuclear quantum effects through state-of-the-art computational approaches,”...

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)...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
