cremeglace writes with this excerpt from ScienceNOW: "You've heard the controversy. Particle physicists predict the world's new highest-energy atom smasher, the Large Hadron Collider (LHC) near Geneva, Switzerland, might create tiny black holes, which they say would be a fantastic discovery. Some doomsayers fear those black holes might gobble up the Earth — physicists say that's impossible — and have petitioned the United Nations to stop the $5.5 billion LHC. Curiously, though, nobody had ever shown that the prevailing theory of gravity, Einstein's theory of general relativity, actually predicts that a black hole can be made this way. Now a computer model shows conclusively for the first time that a particle collision really can make a black hole." That said, they estimate the required energy for creating a black hole this way to be roughly "a quintillion times higher than the LHC's maximum"; though if one of the theories requiring compact extra dimensions is true, the energy could be lower.

ruphus13 writes "Nmap has a new release out, and it's a major one. It includes a GUI front-end called Zenmap, and, according to the post, 'Network admins will no doubt be excited to learn that Nmap is now ready to identify Snow Leopard systems, Android Linux smartphones, and Chumbies, among other OSes that Nmap can now identify. This release also brings an additional 31 Nmap Scripting Engine scripts, bringing the total collection up to 80 pre-written scripts for Nmap. The scripts include X11 access checks to see if X.org on a system allows remote access, a script to retrieve and print an SSL certificate, and a script designed to see whether a host is serving malware. Nmap also comes with netcat and Ndiff. Source code and binaries are available from the Nmap site, including RPMs for x86 and x86_64 systems, and binaries for Windows and Mac OS X. '"

hollywoodb writes "The first carbon tax to reduce the greenhouse gases from imports comes not between two nations, but between two states. Minnesota has passed a measure to stop carbon at its border with North Dakota. To encourage the switch to clean, renewable energy, Minnesota plans to add a carbon fee of between $4 and $34 per ton of carbon dioxide emissions to the cost of coal-fired electricity, to begin in 2012 ... Minnesota has been generally pushing for cleaner power within its borders, but the utility companies that operate in MN have, over the past decades, sited a lot of coal power plants on the relatively cheap and open land of North Dakota, which is preparing a legal battle against Minnesota over the tariff."
