Lab Team says that they've released a mod called qCraft to enable kids (and adults) to play around with blocks that exhibit behaviors like quantum entanglement, superposition and observer dependency. qCraft obviously isn't a perfect scientific simulation, but it's a fun way for players to experience a few parts of quantum mechanics outside of thought experiments or dense textbook examples. The team doesn't know the full potential of what you can make with the mod, but they are excited to see what Minecraft's players can discover."
Tusentals rumäner demonstrerade i dag mot planerna på att amerikanska Chevron ska leta skiffergas i landets östra del, och mot ett kanadensiskt företags planer på att öppna en stor guldgruva i landet.
Hugh Pickens DOT Com writes "Rachel Oswald reports that the Union of Concerned Scientists, an independent science advocacy organization, says that the United States should cancel plans to build a multi-billion dollar plutonium research facility in New Mexico and criticizes Obama administration plans for nuclear facilities and weapons. They argue that the plans to build new fissile-material handling plants are unnecessarily ambitious given the expected future downward trajectory of the U.S. nuclear arsenal. The proposed Chemistry and Metallurgy Research Replacement plant (CMRR) building at Los Alamos would replace a Cold War-era site at a cost of $6 billion. It is intended to assist in ensuring new and existing plutonium pits are in working order absent a return by the country to nuclear-weapons testing. The 81-page UCS report, 'Making Smart Security Choices,' (PDF) says if the U.S. carries out limited reductions of its nuclear arsenal over the next-quarter century — as President Obama has said he would like to do — current facilities at Los Alamos can produce sufficient plutonium cores to maintain the warhead stockpile. The CMRR complex is designed to have the capacity to produce between 50 and 80 plutonium pits annually even though no more than 50 cores are needed yearly and Los Alamos currently has that production capability, says report co-author Lisbeth Gronlund. 'The idea that you would need to produce up to 80 [cores] is not warranted,' says Gronlund. 'We think it's time just to cancel the whole thing.'"
