Dark matter finds new home in old gold mine

Lead is a town of about 3,100 residents, about a half-hour from the Wyoming border. Nestled nearly 5,000 feet beneath the earth, is a laboratory that could help scientists answer some pretty heavy questions about life, its origins and the universe. Yes, we’re talking about dark matter. Regular matter — people and planets, for example — make up about 4 percent of the total mass-energy of the universe, he said. Dark matter makes up about 25 percent. Dark matter is too sensitive to detect in normal laboratories, but one so far underground would help shield it from pesky cosmic radiation. Also, the LUX detector (Large Underground Xenon, the world’s most sensitive dark-matter detector) is submerged in water, further insulating it. The article published on the Herald Tribune provides more details about this experience which could lead to unexpected results!



One day, we will use a neutrinophone, like in Star Trek

This is the kind of news I like. If you thought your new mobile phone was the best ever made, you’re wrong. What about a phone using neutrinos? What about a neutrinophone? Jeff Nelson is the Cornelia B. Talbot Term Distinguished Associate Professor of Physics at William & Mary and in this article, he explains that the neutrinophone demonstration was a side project stemming from neutrino research at the Fermi National Accelerator Laboratory. About the neutrinos: Neutrinos are mysterious subatomic particles emitted in unimaginable numbers by nuclear reactions. Despite their high numbers, scientists are just now learning about the characteristics of neutrinos. William & Mary’s physicists are involved in several large multinational collaborations aimed at learning about the properties of neutrinos. In addition to MINERvA and the other Fermilab experiments, William & Mary researchers are involved in other neutrino investigations, most notably the Daya Bay initiative in China. How it works: The beam of neutrinos  travels through hundreds of meters of rock on the way to the MINERvA detector, which Nelson explains is designed to study neutrino interactions in detail. For communication over the neutrinophone, the physicists used a simple 1-0 binary code. “If you saw neutrinos, it was a zero;…



Space Exploration Technologies (SpaceX) has launched!

Yesterday I have seen something amazing whike orbit Earth: Space Exploration Technologies (SpaceX) successfully launched its Falcon 9 rocket carrying a Dragon spacecraft to orbit in an exciting start to the mission that will make SpaceX the first commercial company in history to attempt to send a spacecraft to the International Space Station. I have seen the SpaceX’s Falcon 9 rocket and if you don’t know yet what SpaceX is about, here is the press release: At a press conference held after the launch, SpaceX CEO and Chief Designer Elon Musk began, “I would like to start off by saying what a tremendous honor it has been to work with NASA. And to acknowledge the fact that we could not have started SpaceX, nor could we have reached this point without the help of NASA… It’s really been an honor to work with such great people.” The vehicle’s first stage performed nominally before separating from the second stage. The second stage successfully delivered the Dragon spacecraft into its intended orbit. This marks the third consecutive successful Falcon 9 launch and the fifth straight launch success for SpaceX. “We obviously have to go through a number of steps to berth with the Space…
