San Francisco faces wireless industry in court over radiation warnings

The City of San Francisco will face off in court with the wireless industry today in a hearing that may determine if the local government will be allowed to force retailers selling cell phones within city limits to disclose possible health risks to consumers before they buy mobile devices.

In 2010, the San Francisco Board of Supervisors and then-mayor Gavin Newsom approved legislation that would require manufacturers to provide information about the potential health risks associated with using cell phones.

Specifically, the ordinance required retailers to put up posters in stores that sell cell phones warning of potential risks. It … Read more

The main perk of Starbucks-Square deal

Wednesday's top headlines are served with a low-fat triple shot of mobile news:

You may wonder why it matters that Square partnered with Starbucks. Customers could already pay for coffee by using the Starbucks app and show their phone screen to the barista. And how much time does that really save compared to taking out your wallet?

This deal is all about awareness. Seeing the Square logo in stores will help people get more comfortable with the idea of phones being a wallet replacement. Apple will also be pushing this concept in iOS 6 with the Passbook app that … Read more

U.S. report: FCC's cell phone radiation guidelines outdated

The Federal Communications Commission should review its cell phone radio-frequency (RF) exposure limit, which was set 15 years ago, because it does not include testing for potential harm from holding phones directly against the body or factor in the latest research, a government report recommended today.

When the RF exposure limit of 1.6 watts per kilogram specific absorption rate (SAR) was established in 1996, phones were bigger, bulkier, and carried in holsters outside of clothes and not in pockets, said Marcia Crosse, director of health care at the U.S. Government Accountability Office (GAO) and co-author of the report. … Read more

Amazon's got game (and textbook rentals)

Tuesday's top tech stories are out to disrupt your world:

Oh Amazon, what don't you do? Well cross off game development, as it just launched its own studio to make Facebook games and compete with Zynga. It also joined the textbook rental service to face off with eBay's Half.com and BookRenter.

YouTube will no longer be a pre-loaded default app on Apple devices. Apple is dropping the YouTube app for iOS 6, and Google will create a separate app you can download. It's all part of Apple's mission to distance itself from Google.

Congressman introduces new bill for cell-radiation warning labels

Rep. Dennis Kucinich, a democrat from Ohio, introduced a federal bill today that would put warning labels on cell phones and create a national research program to study cell phone radiation levels.

H.R. 6358, named the Cell Phone Right to Know Act, would also require the Environmental Protection Agency to update the standards for specific absorption rate, or SAR, the amount of radio frequency energy absorbed by the body when using a cell phone.

"It took decades for scientists to be able to say for sure that smoking caused cancer. During those decades, the false impression created by … Read more

Study links in-utero exposure to magnetic fields to child obesity

High electromagnetic field levels of household appliances (such as washing machines and hair dryers) and wireless devices (such as laptops and routers) may be at least partially to blame for the rise in childhood obesity in recent years, according to a 13-year study by Kaiser Permanente that followed hundreds of pregnant women and 733 of their children.

After controlling for several factors, including child gender, pre-pregnancy BMI, maternal age at delivery, race, education, breastfeeding, and smoking, researchers write in Nature's Scientific Reports that children exposed to high in-utero levels are nearly twice as likely to be overweight or obese … Read more

High-speed laser sets sights on cancer

Pew pew! From disc drives to sci-fi shooters, we live in a world full of laser beams. And a special laser made waves in the world of medical research this week. Developed by laser applications researchers from the University of Tennessee's Space Institute, it could one day find use as a weapon against cancer.

Known as a femtosecond laser, the high-speed light pulses at one-quadrillionth of a second; when fine-tuned, the powerful beam can be used by doctors to detect, map, and nullify cancerous tumors. … Read more

World's fastest camera detects elusive cancer cells

Modifications to the world's fastest camera are enabling the real-time identification of rare breast cancer cells in blood, with a record low false-positive rate of one cell in a million, according to new research out of UCLA.

"This technology can significantly reduce errors and costs in medical diagnosis," lead author Keisuke Goda, a UCLA program manager in electrical engineering and bioengineering, said in a school news release.

The team's approach could not only pave the way for earlier detection of cancer and monitoring of drug and radiation therapy but also prove useful in urine analysis, water … Read more

FCC to re-examine cell phone radiation standards

The Federal Communications Commission is planning to take a closer look at its standards for cell phone safety to see if the agency needs to revise the 15-year-old guidelines.

Later today, Chairman Julius Genachowski will circulate a notice of inquiry that will look at a series of questions surrounding whether the current standards need to be updated or whether the agency's testing practices should be altered, a source at the commission said. And the agency will also examine whether it needs to make improvements in how it communicates safety information to consumers.

The FCC hopes to get comments from … Read more
