At the cosmic big-picture level, io9 blog’s “Ask A Physicist” feature follows the same basic structure as the Elmo’s World “Ask a Baby” routine that so amused you as a preschooler. That leads to this week’s fascinating question: Do we live in a multiverse, and if so, does that mean that somewhere out there in an alternative reality, you have an evil double who’s just waiting to kill you and take your place?

Wired Science tells us that the world’s most intense X-ray laser also may now become the fastest strobe flash for a camera ever, capable of flashing for intervals as short as a quadrillionth of a second. That’s fast enough to image atomic bonds breaking and proteins taking shape. The trick is doing it without blowing up the particles.
NanoWerk says that GE is exploring the use of nanotechnology to capture carbon emissions from burning fossil fuels. If that works, it could be huge.

The RealClimate blog reports that the Times UK has retracted a January story proclaiming that UN climate officials’ assertions about the effect of climate change induced shifts in precipitation on the Amazon forests were bogus. In fact, the paper now admits, that assertion was based on solid, peer-reviewed scientific studies.
