Each Cell-Phone Tower Creates 18 Babies?! The Difference Between Causation & Correlation

phone-towerThose people living in areas with higher numbers of mobile phone towers have more children, new research is showing (spreadsheet).  Matt Parker at The Guardian’s Notes & Theories blog did the analysis of publicly available data and found the correlation:

Could it be possible that mobile phone radiation somehow aids fertilisation, or maybe there’s just something romantic about a mobile phone transmitter mast [aka tower] protruding from the landscape?

The data show that there is a very strong correlation between the number of cell phone towers and the birth rate in communities. For every additional phone tower, there are 17.6 more babies than the national average, Parker writes in his blog post:

When a regression line is calculated it has a “correlation coefficient” (a measure of how good the match is) of 98.1 out of 100. To be “statistically significant” a pattern in a dataset needs to be less than 5% likely to be found in random data (known as a “p-value”), and the masts-births correlation only has a 0.00003% probability of occurring by chance.

With all that fancy math talk, this sounds pretty conclusive, huh? But read on.

Pregnant Women Need Fear No Cell Phone Radiation: Belly Armor Is Here!

prego phoneIf requiring stores to label their cell phones with radiation-output levels wasn’t enough, San Francisco has found a new way to revel in cell phone hysteria: Now one of its trendy maternity boutiques sells radiation-shielding maternity clothes.

These clothes are specifically designed to shield their little unborn hipster babies from computer and cell phone radiation. Radiation-shielding maternity clothing has been popular in China for years, but a young company is now marketing its line of Belly Armor directly to San Francisco’s expectant mothers.

The clothing, which start at $59 for a T-shirt, is made by a company called RadiaShield, whose website encourages expectant mothers to “protect their child within” from the radiation of daily lives. Fact check: most of the radiation that a cell phone emits is actually a low-frequency, non-harmful type of radiation called non-ionizing radiation. It doesn’t contain enough energy to remove electrons from an atom, unlike higher-energy, higher-frequency, known-to-be harmful radiations like x-rays and UV light.

Can Chatting on Your Cell Phone Cause It to Recharge? Researcher Says Yes

cell-phone-pic.jpgTired of running out of cell phone juice in the middle of a conversation? A professor at Texas A&M University may have just the answer for turning your chatter into power.

Chemical engineering professor, Tahir Cagin is using piezoelectrics, a material made of either crystals or ceramics, to generate electricity. Piezoelectrics were used in World War I in sonar devices. Today, they’re found in microphones, inkjet printers, and even cigarette lighters. The Defense Advanced Research Projects Agency is making a shoe with piezoelectrics that can change the energy created by walking into electric power for charging soldiers’ equipment. Some European clubs even use them to transform the dance power from late night partiers into power to light up the club.

Cagin discovered that when piezoelectrics are small and thin (between 20 and 23 nanometers to be exact), twice the amount of energy is created. By finding the ideal length, he was able to convert the mechanical energy it creates into electric power.
