3D Electrons Viewed At High Speed
2012-09-18 13:57:25

Lee Rannals for redOrbit.com - Your Universe Online A team of researchers at MIT are trying to unlock the mysteries of a promising material for future electronic devices. Scientists have managed to create three-dimensional "movies" of electron behavior in a topological insulator (TI), which were first discovered a few years ago. TIs are considered to hold great promise for new kinds of electronic devices, and having a better understanding of the unusual behavior within the material...

Neutrinos Can Alter Exploding Star Physics
2012-08-22 10:27:27

April Flowers for redOrbit.com - Your Universe Online Within the heart of exploding stars, sparse halos of neutrinos exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent events. Neutrinos are one of the fundamental particles that make up the Universe. Although neutrinos are similar to the electron, they have one important difference; they carry no electrical charge. Being electrically neutral, they are not...

In Neutrino-less Double-beta Decay Search

Pocar, Kumar and the team of 60 scientists using an instrument called the EXO-200 detector, succeeded in setting a new lower limit for the half-life of this ephemeral nuclear decay; though no one has yet seen it, important progress was made Physicists Andrea Pocar and Krishna Kumar of the University of Massachusetts Amherst, part of an international research team, recently reported results of an experiment conducted at the Enriched Xenon Observatory (EXO), located in a salt mine one-half...

Scientists from the UK's National Physical Laboratory have developed a nano-device which could change the way we define electrical current A team of scientists at the National Physical Laboratory (NPL) and University of Cambridge has made a significant advance in using nano-devices to create accurate electrical currents. Electrical current is composed of billions and billions of tiny particles called electrons. NPL scientists have developed an electron pump — a nano-device —...

Stubborn Electron Problem Knocked Out With New Method
2012-07-04 10:57:15

A newly published article in Physical Review Letters eliminates one of the top unsolved theoretical problems in chemical physics as ranked by the National Research Council in 1995. Scientists now can more accurately predict the dynamic behavior of electrons in atoms and molecules in chemical reactions that govern a wide range of phenomena, including the fuel efficiency of combustion engines and the depletion of the atmospheric ozone. The paper by David Mazziotti, professor in chemistry at...

CERN Confirms Neutrinos Not Faster Than Light
2012-06-11 06:29:34

Einstein´s Theory Of Relativity Preserved Physicists working at the European Center for Nuclear Research (CERN) in Switzerland on Friday concluded once and for all that neutrinos are definitely not faster than the speed of light, preserving Einstein´s Theory of Special Relativity that was challenged by earlier experiments. The challenge was first made last year when researchers published results of an experiment that seemed to indicate that neutrinos were moving about 3.7...

Physicists Make Closest Measurement Of Neutrinoless Double-Beta Decay Yet
2012-06-05 03:43:51

Physicists searching for a hypothetical and rare process involving radioactive decay of atomic nuclei have gotten their most sensitive results to date, suggesting that these mysterious particles behave like other elementary particles at the quantum level. If such a discovery can be made, the researchers said the process could have profound implications for how scientists understand the fundamental laws of physics and could help solve some of the biggest mysteries of the universe. The...

A strong laser beam can remove an electron from an atom — a process which takes place almost instantly. At the Vienna University of Technology, this phenomenon could now be studied with a time resolution of less than ten attoseconds (ten billionths of a billionth of a second). Scientists succeeded in watching an atom being ionized and a free electron being "born". These measurements yield valuable information about the electrons in the atom, which up until now hasn't been experimentally...

The behavior of some of the most elusive particles in the known universe can be simulated using three atoms in a lab, researchers at the Centre for Quantum Technologies (CQT) at the National University of Singapore have found. Principal Investigator Dimitris G. Angelakis and his group members Changsuk Noh and Blas Rodriguez-Lara have devised a scheme that uses the quantum states of three charged ions to simulate the 'oscillations' of neutrinos. The proposal is published in the March issue...

New Experiments Find Neutrinos Did Not Travel Faster Than Light
2012-03-17 04:37:23

Neutrinos that appeared to travel faster than the speed of light during an experiment last year actually travelled at exactly light speed, new research from the European Organization for Nuclear Research (CERN) has revealed. According to CNET reporter Stephen Shankland, the controversy began in September 2011, when the members of a CERN experiment team known as Opera fired neutrinos from the organization's underground particle accelerator near Geneva to the Gran Sasso National Laboratory...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
