When I have done workshops for aspiring science journalists/writers, I have three pieces of advice. The first is: Don't defend science. It doesn't need defending.

But it's easier said then done. If you spend some time in science media culture, you will invariably find a person saying something pithy like "Science: It works, bitches" but then raging about some attack on science and defending it with shrill verbage and name-calling and conspiracy theories.

If science works, you don't need to defend it with claims that Big Oil is funding climate denial or that homeopaths and Big Organic fund vaccine and GMO denial.
Here's an intellectual puzzle; which is more real, the viability of wind power as anything more than a sustainable gimmick or Wind Turbine Syndrome?
While former Energy Secretary Stephen Chu is a fine scholar, he seemed to be lost when it came to drafting a federal energy policy that was evidence-based.

It's easy for an academic to postulate that $9 a gallon gas will be 'good' for us but when it comes to managing a national constituency, including a lot of people who will be ruined by expensive gasoline, there has to be some real thought before actions are taken. Government is not a sandbox.

On a per capita electricity production basis, environmentalists are winning the war on energy

Electricity for all, which was once considered the goal of technological progress, is now treated like a giant step on the road to an ecological Apocalypse. As a result, we've increased regulation and decreased generation and the price per kilowatt-hour has gone up and supply per capita has gone down. We can thank a confluence of bad ideas, chiefly subsidies for inefficient and expensive green alternatives, penalties for coal and natural gas, and a war on nuclear science.

I understand why someone living in the city might get a slice of pizza - they don't want to carry a box of pizza back to the office, and there is something nice about sitting down and having a quick bite.

But I have never understood why anyone buys a medium pizza, much less a small. If you understand what a circle is, and you understand what a dollar is, it makes no sense.

First, the dollar. The economics should be obvious; like buying any food in bulk, you can see there are fixed costs. A small pizza or a large has someone making it, it has an oven in a shop. Those costs are fixed regardless of which pizza you get. The actual ingredient differences between a small and a large are not a big cost.

Human exposure to bisphenol A (BPA) has recently been linked to negative health claims, like a decline in reproductive function in adults and stunted neurodevelopment in children, and so people consumed with the 'natural' fallacy have been up in arms about it.  It hasn't quite become 'BPA causes autism' hysteria, like they did with vaccines, but it is getting close. 

Naturally, companies have listened to the nocebo worries of the natural-obsessed and dutifully created BPA-free products and charged more money for them.
