Tuesday Open Thread

Welcome to your Thursday open thread. I’m traveling this week, I’m in West Virginia. So you’ll have to play nice by yourselves. I’m sorry I’ll be missing tomorrow’s Carney-Urquhart debate (7:30 PM at University of Delaware).

Scientific American published a very interesting article on the link between cell phones and brain cancer.

This application of the precautionary principle is the wrong mistake to make. Cell phones cannot cause cancer, because they do not emit enough energy to break the molecular bonds inside cells. Some forms of electromagnetic radiation, such as x-rays, gamma rays and ultraviolet (UV) radiation, are energetic enough to break the bonds in key molecules such as DNA and thereby generate mutations that lead to cancer. Electromagnetic radiation in the form of infrared light, microwaves, television and radio signals, and AC power is too weak to break those bonds, so we don’t worry about radios, televisions, microwave ovens and power outlets causing cancer.

Where do cell phones fall on this spectrum? According to phys i cist Bernard Leikind in a technical article in Skeptic magazine (Vol. 15, No. 4), known carcinogens such as x-rays, gamma rays and UV rays have energies greater than 480 kilojoules per mole (kJ/mole), which is enough to break chemical bonds. Green-light photons hold 240 kJ/mole of energy, which is enough to bend (but not break) the rhodopsin molecules in our retinas that trigger our photosensitive rod cells to fire. A cell phone generates radiation of less than 0.001 kJ/mole. That is 480,000 times weaker than UV rays and 240,000 times weaker than green light!

Even making the cell phone ra di a tion more intense just means that there are more photons of that energy, not stronger photons. Cell phone photons cannot add up to become UV photons or have their effect any more than microwave or radio-wave photons can. In fact, if the bonds holding the key mole cules of life together could be broken at the energy levels of cell phones, there would be no life at all because the various natural sources of energy from the environment would prevent such bonds from ever forming in the first place.

I love how the article explained how the principles of physics say that a link is not possible. Not that this will stop people from continuing to say they’re linked.

Think Progress put together a video of Republicans trying and failing to find spending to cut.

In interview after interview, journalists have pushed, and even begged, GOP leaders for specifics, always to no avail. When pressed, they hem and haw, often appearing uncomfortable — and in the case of Sen. Judd Gregg (R-NH), visibly angry — but can offer nothing more than cop-out answers like repealing unsent stimulus money or an “across the board” cut on all spending. ThinkProgress has compiled some of the more embarrassing of these moments:

One question was “what painful choice are Republicans prepared to make?” They can’t name one – that’s because they’re not serious.
