Submission + - Weyl Fermions Found, a Quasiparticle That Acts Like a Massless Electron (ieee.org) 1

An anonymous reader writes: After an 85-year hunt, scientists have detected an exotic particle, the âoeWeyl fermion,â which they suggest could lead to faster and more efficient electronics and to new types of quantum computing.

Electrons, protons, and neutrons belong to a class of particles known as fermions. Unlike the other major class of particles, the bosons, which include photons, fermions can collide with each otherâ"no two fermions can share the same state at the same position at the same time.

Whereas electrons and all the other known fermions have mass, in 1929, mathematician and physicist Hermann Weyl theorized that massless fermions that carry electric charge could exist, so-called Weyl fermions. âoeWeyl fermions are basic building blocks; you can combine two Weyl fermions to make an electron,â says condensed matter physicist Zahid Hasan at Princeton University.

Grad Student Project Uses Wikis To Stash Data, Miffs Admins 268

Anonymous writes "Two graduate students at the Ivy League's Brown University built a P2P system to use abandoned wiki sites to store data. The students were stealing bandwidth from open MediaWiki sites to send data between users as an alternative to BitTorrent. There was immediate backlash as site operators quickly complained to the University. The project appears to be shutdown, but many of the pages still remain on the web. The project homepage was also taken down and the students posted an apology this afternoon." The same submitter links to two different forum discussions on the project.
