Tiny spectrometer offers precision laser calibration

05-10-2007 · EurekAlert!

A tiny device for calibrating or stabilizing precision lasers has been designed and demonstrated at NIST, and could replace table-top-sized instruments used for laser calibration in atomic physics research, could better stabilize optical telecommunications channels, and perhaps could replace and improve on the precision of instrumentation used to measure length, chemicals or atmospheric gases.

    11-30-2006 · EurekAlert!
    Using an ultra-stable laser to manipulate strontium atoms trapped in a "lattice" made of light, scientists at JILA (a joint institute of NIST and the University of Colorado at Boulder) have demonstrated the capability to produce the most precise "ticks" ever recorded in an optical atomic clock—techniques that may be useful in time keeping, precision measurements of high frequencies, and quantum computers using neutral atoms as bits of information.

  7. Gold nanoparticle probes may allow earlier cancer detection
    12-23-2007 · EurekAlert!
    Using tiny gold particles embedded with dyes, researchers have shown that they can identify tumors under the skin of a living animal. These tools may allow doctors to detect and diagnose cancer earlier and less invasively. Studded with antibody fragments called ScFv peptides that bind cancer cells, the gold particles grab onto tumors after their injection into a mouse. When illuminated with a laser beam, the tumor-bound particles send back a signal that is specific to the dye.

  9. Study of planarians offers insight into germ cell development
    04-24-2007 · EurekAlert!
    The planarian is not as well known as other, more widely used subjects of scientific study -- model creatures such as the fruit fly, nematode or mouse. But University of Illinois cell and developmental biology professor Phillip Newmark thinks it should be. As it turns out, the tiny, seemingly cross-eyed flatworm is an ideal subject for the study of germ cells, precursors of eggs and sperm in all sexually reproducing species.
