vanstinator writes "Today Dropbox has released a revised Terms of Service agreement due to the controversy caused by their recent update. This new version clarifies their position on data ownership and makes it very clear that you, and only you, have a right to your data. This is welcome news to any serious Dropbox user." On the downside, though, NorbMan writes that a company called FilesAnywhere.com is "suing Dropbox, Inc. for trademark infringement. The complaint alleges that FilesAnywhere has been using the term 'DROPBOX' since 2004 as part of its service, and that Dropbox, Inc. has also closely duplicated one of its logo designs."

Science News reports on a paper to be published in Physical Review Letters in which an international team of researchers describes their computer simulation of the most violent collision imaginable: two black holes colliding head-on at nearly light-speed. Even in this extreme scenario, Roger Penrose's weak cosmic censorship hypothesis seems to hold — the resulting black hole (after the gravitational waves have died down) retains its event horizon. "Mathematically, 'naked' singularities, or those without event horizons, can exist, but physicists wouldn't know what to make of them. All known mechanisms for the formation of singularities also create an event horizon, and Penrose conjectured that there must be some physical principle — a 'cosmic censor' — that forbids singularity nakedness ..."
