Lead Ingots From Shipwrecks Being Used To Hunt For Dark Matter
2013-12-02 08:18:12

Gerard LeBlond for redorbit.com - Your Universe Online A Roman vessel carrying ingots of lead, which was removed from the Sierra of Cartagena, sank more than two thousand years ago off the coast of Sardinia. Now, more than a hundred of these lead bricks have been used to build the ‘Cryogenic Underground Observatory for Rare Events’ (CUORE), an advanced detector of almost weightless subatomic particles (neutrinos) and is located at the Gran Sasso National Laboratory in Italy....

Search For Dark Matter: XENON100 Search Sets Record Limits
2012-07-19 06:09:01

Scientists from the XENON collaboration announced a new result from their search for dark matter. The analysis of data taken with the XENON100 detector during 13 months of operation at the Gran Sasso Laboratory (Italy) provided no evidence for the existence of Weakly Interacting Massive Particles (WIMPs), the leading dark matter candidates. Two events being observed are statistically consistent with one expected event from background radiation. Compared to their previous 2011 result the...

Faulty Wire To Blame For OPERA’s Speed Of Light Experiment Results
2012-02-23 10:14:01

A claim by scientists working at CERN that neutrinos had traveled faster than light in a September experiment has been proved untrue, after further investigation led them to find a faulty wire connection between a timer and a computer. The US journal Science reported on Wednesday that the 60-nanosecond discrepancy that led physicists to believe neutrinos were traveling faster than the speed of light was in fact the conclusion of a bad connection in a fiber optic cable connecting a GPS...

Fast Than The Speed Of Light? Not So Fast Scientists Say
2011-11-21 09:22:37

Italian scientists who had seemingly found further evidence that neutrino particles were in fact traveling faster than the speed of light based on experiments have been dealt a major blow over the weekend by another team working at the Gran Sasso laboratory in Italy that claims the evidence must be flawed, according to a recent Reuters report. An announcement in September by a team of scientists working on the OPERA (Oscillation Project with Emulsion-tracking Apparatus) experiment claiming...

An International team of scientists in the XENON collaboration, including several from the Weizmann Institute, announced on Thursday the results of their search for the elusive component of our universe known as dark matter. This search was conducted with greater sensitivity than ever before. After one hundred days of data collection in the XENON100 experiment, carried out deep underground at the Gran Sasso National Laboratory of the INFN, in Italy, they found no evidence for the existence of...

An international team including scientists from Princeton University has detected subatomic particles deep within the Earth's interior. The discovery could help geologists understand how reactions taking place in the planet's interior affect events on the surface such as earthquakes and volcanoes. Someday, scientists may know enough about the sources and flow of heat in the Earth to predict events like the recent volcanic eruption in Iceland. The finding, made by the Borexino Collaboration at...
