Tegra 3 is comprised of a quad-core primary CPU complex with a 5th companion core for lower-end processing requirements and power management. The chip can scale up to 1.4GHz on a single core and 1.3GHz on up to four of its cores, while the companion core operates at 500MHz.

Submission + - High-Tech Gas Drilling Is Fouling Drinking Water (sciencemag.org)

Submitted by sciencehabit
sciencehabit writes: Drilling for natural gas locked deep in a shale formation--a process known as fracking--has seriously contaminated shallow groundwater supplies beneath far northeastern Pennsylvania with flammable methane. That’s the conclusion of a new study, published today in the Proceedings of the National Academy of Sciences. The analysis gives few clues, however, to how pervasive such contamination might be across the wide areas of the Northeast United States, Texas, and other states where drilling for shale gas has taken off in recent years.
