Cellphone radiation raises concerns

Better to be safe than sorry.
You’ve heard that expression a million times.
Given that it’s Breast Cancer Awareness Month, Dr. Paul Michael, of Comprehensive Cancer Centers of Nevada, wants you to hear it again in relation to cellphones and the disease that still strikes more than 230,000 women each year.
Even though he stresses serious research on cellphone radiation and breast cancer is in its infancy and there is no conclusive evidence linking the two, the former American Cancer Society board member says “it’s not a good idea” for anyone concerned about getting the disease to risk doing what many young women consider hip today — tucking an active cellphone into their bra while they drive, jog, shop or sit in movie theaters.
For years, he said, scientists have been studying — basically in relation to brain cancer — the form of energy given off by cellphones known as radiofrequency waves, a type of nonionizing radiation that the International Agency for Research on Cancer has classified as “possibly carcinogenic to humans.”
Because all expert agencies agree that evidence of a possible link between cellphones and cancer is limited and more research is needed to look at possible long term effects — a kind of “maybe” conclusion that often becomes easy for some to dismiss — Michael suggested that warnings by cellphone manufacturers themselves should make women more cautious about where they carry and use cellphones.
“They put in their instruction manuals that people shouldn’t have the phones touching them,” he said.
It’s in the fine print, but it’s there. An Apple iPhone 4 warning reads: “When using iPhone near your body for voice calls or for wireless data transmission over a cellular network, keep iPhone at least 15 mm (5/8 inch) away from the body, and only use carrying cases, belt clips or holders that do not have metal parts and that maintain at least 15 mm (5/8 inch) separation between iPhone and the body.”
If that distance isn’t kept, the warning continues, “guidelines for self-exposure can be exceeded.”
(Apple spokesmen have consistently noted that the iPhone’s radio-frequency energy is well within the limits set by the Federal Communications Commission and governing agencies of other countries.)
Motorola warns W180 phone users to keep the active device one full inch away from their body, if not using a company approved “clip holder, holster, case or body harness.”
What has caused cancer prevention activists to start looking more at possible linkage between cellphones and breast cancer is the work of Devra Davis, the founding director of the center for environmental oncology at the University of Pittsburgh Cancer Institute as well as the founder of Environmental Health Trust and the author of “DISCONNECT: The Truth About Cellphone Radiation.”
“Experimental studies show that cellphone radiation accelerates the growth of breast cancer cells,” she wrote.
Davis supports women using a headset or speakerphone with a cellphone, which the American Cancer Society says substantially reduces radiation exposure, as does holding a cellphone away from the body.
As she pushes for more research, Davis shares the stories of women, including Tiffany Frantz of Pennsylvania, who says she developed breast cancer at a spot where she kept her cellphone in her bra against her bare skin 12 hours a day. At 21, she underwent a mastectomy on her left breast.
Though he admits that what he calls “anecdotal evidence” can be powerful, medical oncologist Michael won’t allow himself to say there is a definite linkage between breast cancer and cellphones carried in bras.
That connection, he said, can only be definitively made with a study that follows many women.
Still, in the absence of scientific proof, Michael understands that what happened to Frantz and others like her may cause parents to caution their daughters about where they’re carrying their cellphones.
That, he said, would be a good thing.
“I don’t know if cellphones carried next to the breast cause cancer,” he said. “Not all radiofrequency waves cause cancer. But I do know from a recent study that young women are getting more aggressive and larger tumors than older women. Is that because of diet, pollution, cellphones or whatever? I don’t know. But we also know the people who make cellphones say they shouldn’t be carried that way. I think we know enough about this to say it’s better to be safe than sorry when it comes to where you’re carrying your cellphone.”

Paying with a fingerprint on Feb. 15, 2013.
FIDO Alliance claims that the first biometric scanners, designed to eliminate the need for traditional web and app passwords, are expected to make their debut on Android handsets within the next six months.
A group of leading companies that includes Lenovo, PayPal and Google in its ranks, the FIDO Alliance is on a mission to make web authentication far more secure without making the process of logging on needlessly complicated. In February it set out on a mission to create a scalable open standard that any manufacturer or web-based service can integrate that will replace the text-based password with a biometric alternative. Eight months on, it looks as if the initiative is bearing fruit.
In an interview with USA Today, FIDO's president and former chief information security officer for PayPal Michael Barrett revealed that the alliance's growing power and support means that the first step towards safer, more secure internet use is just six months away, meaning that soon he'll be able to swipe a finger across a smartphone in order to access his online accounts.

Barrett makes no secret of his hatred of the traditional password and its frailties. During a keynote address at Interop Las Vegas in May, he declared all-out war on it. "Our intention is to really obliterate, within a certain number of years, both passwords and PINs and see the whole Internet -- including internally in enterprises -- obliterate user IDs and passwords and PINs from the face of the planet," he said.
Apple's latest flagship phone, the iPhone 5S, already sports a fingerprint scanner that the company calls Touch ID and which is currently limited to the locking and unlocking of the phone's screen and as a way of authenticating the owner when making iTunes and App Store purchases. However, a number of analysts believe that Apple's leap of biometric faith will help pave the way for other device makers to follow suit and push the technology into the mainstream.
"What Apple has done with Touch ID is to improve the usability of identity verification on mobile devices -- to make it more convenient," said Alan Goode, MD of analyst firm GoodeIntelligence.com and long-time biometrics champion, "I believe that the main driver for adoption of biometrics into consumer electronic devices is the mass adoption of smart mobile devices and the challenges this poses for strong authentication and identity verification -- in other words how do we securely prove identity on a mobile device without affecting the user experience. Passcodes and One-Time-Passwords are not the most convenient way to prove identity on a mobile device, especially when we are on the move."
And while Bennett too is happy to see Apple upping its security game, he points out that the company is not currently a FIDO member (unlike its arch rival Google) and therefore Touch ID is not currently compatible with FIDO's own biometric technology. "Our view is that it's possible Apple might choose to start using FIDO, but that's probably a couple of years out," he told USA Today.
And while consumers should rejoice that the traditional password's days are finally numbered, they shouldn't expect an overnight revolution. Adoption will take time, bugs will have to be ironed out and new user habits will have to be learned.
As fellow FIDO member and CEO of Nok Nok Labs, Phil Dunkelberger, says in the same interview: "We didn't create the current authentication mess overnight, so it's going to take us a while to fix it. We need to educate the marketplace that it is possible to make things more secure for business and easier for consumers, while still ensuring that legitimate privacy concerns are respected."
For now, the best option for security-conscious consumers is to consider a password manager, such as Last Pass or 1password. They create fiendishly difficult, impossible-to-remember, and most importantly, unique passwords for each web service a consumer accesses and stores them all behind a master password. When arriving on a log-in page, the password manger, if activated, will automatically fill in all security fields.

Nexus5_Service_Manual
Well there it is. What could be the service manual for the Nexus 5 has surfaced. It confirms a lot of what we were already assuming along with some interesting notes. Hence its presumed name, the screen will be nearly 5-inches with a 1080p display (IPS TFT, too). On the inside, the new Nexus will be no slouch. Powering it is the Snapdragon 800 processor clocked at 2.3GHz and 2GB of RAM to manage tasks. Hit the break for more details, highlights from the manual, and the full manual itself.
An area of concern is the battery life as the service manual shows a 2300mAh size. While this would be enough for the average user, others are worried that they would burn right through it. Other minor details include an OIS camera like the LG G2 (which the device is modeled after), a micro SIM slot, and wireless charging.
Highlights from manual:
  • 4.95″ 1080p display (IPS TFT)
  • 32GB internal storage (unknown if there are other sizes), 2GB RAM
  • Snapdragon 800 at 2.3GHz (MSM8974)
  • 8MP OIS rear camera, 1.3MP front camera
  • 2300mAh battery
  • Micro SIM slot
  • Wireless charging
  • NFC
  • Bluetooth 3.0 (likely to be 4.0 since this is a draft version)
  • UMTS/GSM/CDMA/LTE compatibility
