In late October 2011, the Sunway BlueLight MPP made headlines as China’s first high-performance computer to harness the power of a homegrown chip, the ShenWei SW1600. And the Dawning 6000, scheduled to come on line in December 2011, will use another indigenous processor, the Godson-3B. These are supercomputers that China can truly call its own.

At press time, engineers were busy optimizing the Dawning 6000’s ability to run Linpack—the benchmark software library used to rank computers in the Top500 list. The Sunway BlueLight, a petaflops-level supercomputer, has already been put through its Linpack paces and claimed 14th place in the November Top500 ranking. But don’t be fooled: Neither machine is a speed demon. Consider them rather as steps toward technological independence.

The prototype patch in this research is shown in (a) on the left; on the right (b) is the kind of head rotation that can yield an electrical response from the patch.

Nelson Sepúlveda was sitting in the stands at Spartan Stadium, watching his hometown Michigan State players bash heads with their cross-state football rivals from the University of Michigan, when he had a scientific epiphany.

Perhaps the nanotechnologies he had been working on for years—paper-thin devices known as ferroelectret nanogenerators that convert mechanical energy into electrical energy—could help save these athletes from the ravages of traumatic brain injury.
