Will America’s Power Grid Be Able To Keep Pace With Future Demand?
| Will America’s Power Grid Be Able To Keep Pace With Future Demand? America’s power grid today resembles the country’s canal system of the 19th Century. A marvel of engineering for its time, the canal system eventually could not keep pace with the growing demands of transcontinental transportation. |
| Bio-Nanomachines: Proteins As Resistance Fighters Friction limits the speed and efficiency of macroscopic engines. Is this also true for nanomachines? Researchers recently used laser tweezers to measure the friction between a single motor protein molecule and its track. The team found that also within our cells, motors work against the resistance of friction and are restrained in its operationEUR |
