GERDA sets new limits on extremely rare decay Neutrinos are the most elusive particles having extremely weak interactions with all other particles. They have rather unusual properties and are even expected to be identical with their own antiparticles. So far this property is, however, not experimentally verified even though many studies of neutrinos over the last 60 years have already boosted our understanding of elementary particle physics. Now scientists of the GERDA collaboration...

Dark Matter Detector Gets Helping Hand From Livermore Team
2012-11-16 05:58:38

April Flowers for redOrbit.com - Your Universe Online Nearly a mile underground beneath the Black Hills of South Dakota, scientists from Lawrence Livermore National Laboratory (LLNL) are using a tank to make key contributions to a physics experiment that will look for one of nature's most elusive particles, "dark matter." The Large Underground Xenon (LUX) experiment located at the Sanford Underground Research Facility in Lead, SD is the most sensitive detector of its kind to look for...

Neutrino Experiment Installation Underway
2012-09-07 07:20:12

April Flowers for redOrbit.com - Your Universe Online The first block of what will be the largest, most advanced neutrino experiment in North America is now being installed in Minnesota. On track to come online in 2013, the NuMI Off-Axis Appearance experiment — NOvA for short — will study the properties of neutrinos, such as their masses, and investigate whether they helped give matter an edge over antimatter after both were created in equal amounts in the Big Bang....

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
2012-07-19 11:32:15

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...

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...

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...

Image 1 - Researchers Send Neutrino Message Through Solid Stone
2012-03-16 03:44:13

For the first time, a team of U.S. researchers have successfully used a beam of neutrinos--extremely low mass particles that can travel at the speed of light--to transmit a message through an obstacle. According to a Wednesday article from Ars Technica reporter Casey Johnston, the scientists, who were representing the University of Rochester and North Carolina State University (NC State), fired the neutrinos through roughly 780 feet of solid bedrock. When the particles emerged on the other...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
