Ever since the dawn of powered flight, it has been necessary for all aircraft to carry onboard fuel — whether in the form of batteries, fuel, solar cells, or even a human "engine" — in order to stay aloft.
With a laser beam centered on its panel of photovoltaic cells, the lightweight model plane makes the first flight of an aircraft powered by a laser beam inside a building at NASAs Marshall Space Flight Center in Huntsville Ala. (Tom Tschida, NASAs Dryden Flight Research Center)
But a team of researchers from NASAs Marshall Space Flight Center in Huntsville, Ala., NASAs Dryden Flight Research Center at Edwards, Calif., and the University of Alabama in Huntsville is trying to change that.
They have now chalked up a major accomplishment… and a "first." The team has developed and demonstrated a small-scale aircraft that flies solely by means of propulsive power delivered by an invisible, ground-based laser. The laser tracks the aircraft in flight, directing its energy beam at specially designed photovoltaic cells carried onboard to power the planes propeller.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
