Narwhals May Produce Signature Vocalizations For Communications
10-02-2006 · ScienceDailyScientists have found preliminary evidence that narwhals, Arctic whales whose spiraled tusks gave rise to the myth of the unicorn, produce signature vocalizations that may facilitate individual recognition or their reunion with more distant group members.

- Novel semiconductor structure bends light 'wrong' way -- the right direction for many applications
10-14-2007 · EurekAlert!
A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats.

- Ape gestures offer clues to the evolution of human communication
04-30-2007 · EurekAlert!
Researchers at the Yerkes National Primate Research Center, Emory University, have found bonobos and chimpanzees use manual gestures of their hands, feet and limbs more flexibly than they do facial expressions and vocalizations, further supporting the evolution of human language began with gestures as the gestural origin hypothesis of language suggests.

- Molecular 'signature' protects cells from viruses
10-12-2006 · EurekAlert!
Viruses are cunning little parasites: they breed by forcing the affected cells to do what they want. By fake commands they get them to produce new viruses. However, the cell often notices that there is something fishy going on. Researchers at the University of Bonn and Munich's Ludwig Maximilian University have now discovered why: cells are in a position to attach their "signature" to their commands, whereas viruses cannot. Their findings are published on October 12 in the prestigious journal Science.

- Fiber-based light source promises improvements in food inspection
03-15-2007 · EurekAlert!
A new light source based on fiber-optic technology promises to improve the inspection of food, produce, paper, currency, recyclables and other products. New research revealing this technology will be presented at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC), being held March 25-29 in Anaheim, Calif.

- Harnessing new frequencies
03-28-2007 · EurekAlert!
Modern technology uses many frequencies of electromagnetic radiation for communication, including radio waves, TV signals, microwaves and visible light. Now, a University of Utah study shows how far-infrared light -- the last unexploited part of the electromagnetic spectrum -- could be harnessed to build much faster wireless communications and to detect concealed explosives and biological weapons.

- Mother mice more attuned to pup sounds than others
06-11-2007 · EurekAlert!
Researchers have shown for the first time that the behavioral context in which communication sounds are heard affects the brain's ability to detect, discriminate and ultimately respond to them. Specifically, the researchers found that the auditory neurons of female mice that had given birth were better at detecting and discriminating vocalizations from mouse pups than the auditory neurons in virgin females.

- Ladybugs may be cute, but watch out when they get near wine
03-25-2007 · EurekAlert!
Ladybugs produce a foul-smelling liquid that can be inadvertently processed along with grapes and taint the aroma and flavor of wine. Researchers at Iowa State University say they have identified several compounds that are responsible for the noxious odor, a finding that could lead to new strategies to eliminate the offensive compounds and improve wine quality. The study will be presented in March at the American Chemical Society national meeting in Chicago.
