Laser frequency combs–extraordinarily precise tools for measuring frequencies (or colors) of light–have helped propel advances in timekeeping, trace gas detection and related physics research to new heights in the past decade. While typical lasers operate at only a single or handful of frequencies, laser frequency combs operate simultaneously at many frequencies, approaching a million for some combs. These combs have very fine, evenly spaced "teeth," each a specific frequency,...

Head lice shrivel in study as device hits the market Four years after the LouseBuster prototype made headlines when research showed the chemical-free, warm-air device wiped out head lice on children, a new study reveals that a revamped, government-cleared model is highly effective. "For a louse, it's like sticking your head out a window at 100 miles an hour; they're going to get dried out," says University of Utah biology Professor Dale Clayton, senior author of the study and a founder of...

Optical frequency combs could tame quantum bits Physicists at the University of Maryland have found a way to turn a precision measurement device into a versatile tool for manipulating quantum bits (qubits). The researchers adapted a device known as an optical frequency comb in their novel approach to performing the sorts of quantum data operations that will be vital for future quantum computers. The research appears in this week's issue of Physical Review Letters and is described in a...

Finally, an optical frequency comb that visibly lives up to its name. Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) in the United States have built the first optical frequency comb"”a tool for precisely measuring different frequencies of visible light"”that actually looks like a comb. As described in the Oct. 30 issue of Science,* the "teeth" of the new frequency comb are separated enough that when viewed with a...

On Monday, the daily Haaretz reported that combing your hair throughout the day could lead to hair loss. The researchers, led by Alexander Kirdman of the Hebrew University of Jerusalem, said that 14 women were tested for daily hair loss and combing habits. The team found that those combing more often were losing more hair. "The women who combed twice a day lost three times more hair than those who combed once a day," Kirdman said. "I was surprised by the results, as in medical circles the...

EASTCHESTER, N.Y., March 17 /PRNewswire/ -- FRIED LICE: "You don't have to be such a nitpicker" now has new meaning. Lice Safe, a progressive upstart manufacturing company, is set to introduce the latest in delousing technology. The technology uses the standards set at The Center for Disease Control "CDC" website. The guidelines are clear in stating: "to kill lice and their eggs/nits you must use heat in excess of 130 degrees." Lice Safe was able to adapt a design and secure it with the...

By Wes Woods II SAN DIMAS - Modernization efforts of local schools were detailed with photos and presentations Wednesday night at the Bonita Unified School District board of education meeting. Two schools, Allen Avenue and Gladstone Elementary schools, were two weeks behind schedule, but the board and project managers did not appear concerned. Board president Chuck Coyne said he was not concerned and told project manager Roy Combs of Bernards that "we've seen you catch up two weeks"...

Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. The same NIST group also has shown that this type of laser, when used as a frequency comb"”an ultraprecise technique for measuring different colors of light"”could boost the sensitivity of astronomical tools searching for other Earthlike planets as...

The cockscombs are edible and ornamental plants named for their brightly colored flower heads, comprising the genus Celosia of the family Amaranthaceae (subfamily Amaranthoideae). They are similar in appearance and uses to the amaranths. Silver cockscomb is grown as a leaf vegetable and pseudo-cereal, especially in West and Central Africa and Southeast Asia. It is also the most important leaf vegetable of southern Nigeria. The crested cockscomb is a common garden ornamental plant in...
