Single nanotube makes world's smallest radio
November 2, 2007 12:07 PM - UC Berkeley News Service
Berkeley, California – Physicists at the University of California, Berkeley, have built the smallest radio yet -- a single carbon nanotube one ten-thousandth the diameter of a human hair that requires only a battery and earphones to tune in to your favorite station.The scientists successfully received their first FM broadcast last year -- Derek & The Dominos' "Layla" and the Beach Boys' "Good Vibrations" transmitted from across the room. In homage to last year's 100th anniversary of the first voice and music radio transmission, they also transmitted and successfully tuned in to the first music piece broadcast in 1906, the "Largo" from George Frederic Handel's opera "Xerxes."

Diet, growth are major cancer causes: report
November 1, 2007 09:23 PM - Maggie Fox, Health and Science Editor
WASHINGTON (Reuters) - What people eat and how fast they grow are both significant causes of cancer, but many Americans still incorrectly believe that factors such as pesticides on food are bigger causes, experts reported on Wednesday.
Breastfeeding reduces the risk of cancer for mother and child, and tall people have a higher risk of cancer than shorter people, the report found.
"We need to think about cancer as the product of many long-term influences, not as something that 'just happens,'" Dr. Walter Willett, a nutrition expert at the Harvard School of Public Health in Massachusetts, told a news conference.

Fluorescence discovered in key marine creature
November 1, 2007 01:01 PM -
Fluorescent proteins found in nature have been employed in a variety of scientific research purposes, from markers for tracing molecules in biomedicine to probes for testing environmental quality. Until now, such proteins have been identified mostly in jellyfish and corals, leading to the belief that the capacity for fluorescence in animals is exclusive to such primitive creatures. Green fluorescent proteins were discovered in amphioxus, a fish-like animal found in coastal areas. Scientists at Scripps Institution of Oceanography at UC San Diego have discovered fluorescent-light emitting features in an evolutionarily important marine organism and say such a capacity may be much more prevalent across the animal kingdom than previously believed.
Privacy groups seek "do not track" Web list
November 1, 2007 12:25 PM - Reuters
WASHINGTON (Reuters) - Nine privacy and consumer organizations asked the Federal Trade Commission on Wednesday to create a "do not track" list for Internet users who don't want their online activities tracked, stored and used by advertising networks. Such a list would function much like the FTC's "do not call" registry that consumers can join to prevent telemarketing phone calls, according to the groups, which include the Center for Democracy and Technology, Electronic Frontier Foundation and the Consumer Federation of America. Internet advertising companies and marketers increasingly are collecting information about individuals' Web activities and preferences so as to tailor their advertising messages.
Cat's eye view of DNA sheds light on human disease
November 1, 2007 09:58 AM - Maggie Fox -Reuters
The first full genetic map of a cat -- a domestic pedigreed Abyssinian -- is already shedding light on a common cause of blindness in humans and may offer insights into AIDS and other diseases, researchers reported on Wednesday. And the cat genome shows some surprising qualities that cats and humans appear to have uniquely in common, the researchers report in the journal Genome Research.

Google phone could be tough sell to U.S. carriers
October 31, 2007 01:22 PM - Sinead Carew - Analysis
NEW YORK (Reuters) - Google Inc, which is used to dominating the Web search advertising business, may find negotiating its way into the cell phone market a tougher task. Dealing with America's largest mobile companies, which keep control of devices and features, could force the Web search leader to make concessions that cut into future revenue from wireless, an area Google has long said would be key to growth. So far no U.S. carrier has confirmed working with Google on a new mobile platform. No. 2 U.S. carrier Verizon Wireless is in active talks about putting Google applications on phones it offers, people familiar with the matter told Reuters.
