3 Self-Powered Nanotech (10分)
Nanosize machines need still tinier power plants
By Zhong Lin Wang
The watchmaker in the 1920s who devised the self-winding wristwatch was on to a great idea: mechanically harvesting energy from the wearer’s moving arm and putting it to work rewinding the watch spring.
Today we are beginning to create extremely small energy harvesters that can supply electrical power to the tiny world of nanoscale devices, where things are measured in billionths of a meter. We call these power plants nanogenerators. The ability to make power on a minuscule scale allows us to think of implantable biosensors that can continuously monitor a patient’s blood glucose level, or autonomous strain sensors for structures such as bridges, or environmental sensors for detecting toxins — all running without the need for replacement batteries. Energy sources are desperately needed for nanorobotics, microelectromechanical systems (MEMS), homeland security and even portable personal electronics. It is hard to imagine all the uses such infinitesimal generators may eventually find.
In Brief
★Nanotechnology has huge potential — but those minuscule devices will need a power source that is better than a battery.
★ Waste energy, in the form. of vibrations or even the human pulse, could provide sufficient power to run such tiny gadgets.
★ Arrays of piezoelectric nanowires could capture and transmit that waste energy to nanodevices.
★ Medical devices will likely be a major application. A pacemaker’s battery could be charged so it would not need replacing, or implanted wireless nanosensors could monitor blood glucose for diabetics.

4. Finding Early Signs of Mad-Cow Disease(5分)
Disease damage: This microscopy image shows brain tissue damaged by Creutzfeldt-Jakob (可不译，照搬) disease. Researchers have made a list of blood proteins that act as early indicators of a group of diseases including bovine spongiform. encephalopathy (BSE), also known as mad-cow disease. The human form. of BSE, a fatal degenerative neurological disorder, called Creutzfeldt-Jakob disease
Biotech pioneer: Leroy Hood, president and cofounder of the Institute for Systems Biology, in Seattle, invented several tools, including the automated DNA sequencer that helped make it possible to sequence the human genome. Now, biotech pioneer Leroy Hood explains how Systems Biology will impact medicine.
