A team of researchers at the University of Colorado at Boulder has taken another step in the quest to build a compact, tabletop x-ray microscope that could be used for biological imaging at super-high resolution.
By firing a femtosecond laser - a laser that generates light pulses with durations as short as 100 trillionth of a second - through a gas-filled tube called a waveguide, they were able to create more efficient "laser-like" beams in regions of the spectrum that were previously inaccessible.
The wavelength region over which they generate this "soft" x-ray light efficiently is called the "water-window" region, an important region for biological imaging, according to physics Professor Margaret Murnane. She also is a fellow of JILA, a joint institute of CU-Boulder and the National Institute of Standards and Technology.

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...

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...
