Scientists see solution to critical barrier to fusion
sciencedaily.comFusion occurs when plasmas become hot and dense enough for the atomic nuclei contained within the hot gas to combine and release energy. But when the plasmas in experimental reactors called tokamaks reach the mysterious density limit, they can spiral apart into a flash of light. "The big mystery is why adding more heating power to the plasma doesn't get you to higher density," said David A.

No one understands exactly why. The phenomenon leaves physicists to ponder the molecular question of whether glass is a solid, or merely an extremely slow-moving liquid.

Who Goes There? Verifying Identity Online
sciencedaily.comThe researchers explain that in their novel network structure users do not have identities. Users are contacted by searching for their pseudonyms, which they change frequently. Authentication is done by the users themselves, not by the certification of a central authority. In this network, as there is no identity, there is no identity theft.
