Mobiles Eclipse Landlines As the Voice of the Land
The year ending looks like it will go into the books as the first year in which Americans spent more money on cellphone services than traditional landlines, the industry reports. Combination Of Technologies Works Best Against E. Coli
No one weapon in the food-safety arsenal will take out E. coli 0157:H7, a nasty little pathogen that's becoming far too familiar to Americans, say University of Illinois scientists Scott Martin and Hao Feng. And they should know because they work on this problem in their labs every day. The food science professors work with ozone, high-intensity ultrasound, electrolyzed water, irradiation, and temperature, and they say no treatment singlehandedly can reduce the number of pathogens sufficiently to meet the standards set by the FDA. Scientists Link Genetic Pathway To Development Of Hearing
New research findings detail how sensory hair cells in the ear develop unique shapes that enable the perception of sound. The development of cochlea and hair cells is dependent on a genetic pathway called the PCP (planar cell polarity) pathway. What Determines Sky's Colors At Sunrise And Sunset?
The colors of the sunset result from a phenomenon called scattering. Molecules and small particles in the atmosphere change the direction of light rays, causing them to scatter. Scattering affects the color of light coming from the sky, but the details are determined by the wavelength of the light and the size of the particle. IPods Can Help People Who Stutter
Compared to advancements in modern medicine over the past 70 years, there have been few new treatment options for people who stutter. That's one reason a $50 digital device under development is drawing attention. In contrast, a typical digital speech device costs approximately $5,000. The researcher also determined that many people who stutter may only need an external source of speech initiation to address their problem. Google Cheat Sheet
A quick reference guide to the most popular special operators for Google, including Boolean and adjacency operators, definitions, mathematical calculators, date search, site "info,"and more. [Unlikely] Hotel Guest Pays Bill After 24 Years
After putting up with pangs of conscience for 24 years, a Norwegian finally settled a hotel bill he skipped out on in 1980. Studies Of Population Genetics, Evolution Are An Exercise In Bad Taste
Scientific studies of why foods such as Brussels sprouts and stout beer are horribly bitter-tasting to some people but palatable to others are shedding light on a number of questions, from the mechanisms of natural selection to understanding how our genes affect our dietary habits. Hot Ice To Lubricate Artificial Joints
A recent simulation has shown that thin layers of ice could persist on specially treated diamond coatings at temperatures well above body temperature, which could make ice-coated-diamond films an ideal coating for artificial heart valves, joint replacements, and wear-resistant prosthetics. Genetic Marker Predicts Pig Litter Size
Bigger is often better where litter size is concerned, especially when it comes to piglets. Scientists with the Agricultural Research Service's (ARS) U.S. Meat Animal Research Center in Clay Center, Neb., have identified a genetic marker that could help pig breeders select animals for increased uterine capacity and litter size. This genetic discovery could give swine breeding a boost in efficiency.
