I founded Science 2.0® in 2006 and since then it has become the world's largest independent science communications site, with over 300,000,000 direct readers and reach approaching one billion. Read More »

When it was fashionable to do so, Germany claimed they were scuttling their nuclear power plants. Their energy companies, bolstered by billions of Euros in government subsidies, rushed to replace nuclear energy with solar and other alternative energy schemes.

But the projected increases in efficiencies never came to pass - companies that rely on subsidies are not in any rush to make technology better. And Germany has seen the US send its CO2 emissions from the energy sector drop back to early 1990s levels, and from dirty coal back to early 1980s levels, using natural gas - so now policymakers have decided they want to be a part of it.
In the introduction to Science Left Behind, I wrote about a bizarre effort by MoveOn.org-sponsored (think Tea Party, but of the left) progressives who helped gain control of Congress in the 2006 election to make good on their promises to Make America Green - and how in order to do so, they latched onto every pseudoscientific fairy tale they could, like replacing spoons in the Congressonal cafeteria with the kind made from corn. 
Comic book heroes get into all kinds of crazy situations, everything from alien invaders to losing their powers. Most often, though, might simply makes right -  but what happens when the thing you are fighting gets stronger from being hit? How do you defeat something like that?

It actually happened in "The Mighty Thor" #140 from 1967.

Comics were a lot different in 1967; fantastic, supernatural events were routine plot devices, but even then Marvel was the more 'scientific' of the two large superhero comics companies. Marvel loved genetic mutations and scientists were often heroes or villains but decades ago the resolution of the plot was going to be fast and likely something of a letdown.
There's no greater feel-good fallacy than the belief that organic food is somehow superior to conventionally farmed food. In reality, organic food isn't more environmentally responsible, it is worse, it isn't better for your health, it is worse and, for the most part, it isn't even grown by small farmers, it is giant conglomerates who, like with gluten-free, fat-free or any other food fad, encourage proponents and the mythology of health benefits because they can charge more money.
Dr. James Hamblin at The Atlantic takes a skeptical look at the recent demonizing of gluten and grain and sugars and renewed calls for something resembling a paleo diet. I have been beating the gluten-free horse for a while, of course, to much derision and scorn from people who were not Celiacs but insisted gluten was bad for everyone anyway.
Given the flakiness and rush of shipping at this time of year, if you intend to order something online, you really need to do it today. Sure, you can take a flyer on next week but if you have Amazon Prime and its two-day free shipping, today is the way to go and remain drama free. 

With that in mind, here are some cool science gifts, if you are still stumped:
