San Francisco Decrees Cell Phone Radiation Transparency
Two days ago, San Francisco mandated that all cell phones bear a new label: amount of radiation emitted. A sort of calorie-labeling for health-conscious tech consumers. The science is arguably not set in stone, but the watchdog organization Environmental Working Group (EWG) released a study earlier this year, citing cell phone radiation as being very likely linked to two types of brain tumor, one malignant, one not. (Click here for the three safest and three most dangerous phone models, radiation-wise). EWG and many consumers fear cell phones will turn out to be the cigarette of the 21st century – we’ve all shifted gleefully and without hesitation over to wireless, and may discover too late that our handhelds have been killing us gently.
For me, one of the most compelling reasons to take precautionary action at this point, while the science works itself out, is that cell phones have only really been prevalent for 10 years. When did you get your first? Did you use one as a kid? If you’re a parent, do your children now use cell phones? We just haven’t been using these life-changing gizmos long enough to know – statistically speaking – if they’re taking lives.
A side-note that didn’t get attention in the New York Times’ coverage of Mayor Gavin Newsom’s forward-thinking decision: headsets, headsets, headsets.
For those who can’t afford to splash out on a new low-radiation phone, or who just don’t want to create unnecessary e-waste by chucking a perfectly good phone, a headset may be a good option. Not just any headset, though. Some cut down significantly on the amount of radiation that makes it into the user’s brain, and some don’t.
I use a Blue Tube headset, which is exactly what it sounds like: a headset that connects to your ear by a blue plastic tube (as opposed to continued electric wire). That blue tube conducts sound waves, but not radiation, keeping your brain safe and, ah, sound.

It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
