Yeah, it sounds a little Calvin & Hobbes, but riding around with corrugated cardboard on your head can actually be safer than the plastic and Styrofoam concoctions you get at the bike store. The Kranium cardboard bike helmet absorbs four times more impact energy than equivalent polystyrene. One helmet was smashed five times in a row and still had enough muscle to pass a standard safety test. And yeah, it's waterproof.
Man, is this ad from 350.org ever edgy! First, it has a big picture of Scott Brown -- granted, just his face, not even his pecs or anything, but you know what's implied by a picture of a congressman. Rowr! And just look at those naked facts, parading themselves around so shamelessly. No wonder the Massachusetts Bay Transportation Authority refuses to post it on trains.
If you live west of D.C. and east of Omaha, there's a good chance you're pretty close to one of the 25 dirtiest coal plants in the U.S. Twenty of them are 50 to 100 miles away from major urban areas, according to Climate Progress.
Bourbon's birthday was yesterday, but if you're anything like me, you're still celebrating. So you'll be glad to know that whisky -- we'll go with the Scottish spelling, because this is happening in Scotland -- is the newest addition to the Unlikely Biofuels Club. Helius Energy is building a 7.2-megawatt plant in Scotland that will run off of waste from whisky distilling. Isn't that so much classier than powering your car with Four Loko?
Spanish design firm Play Studios asked kids to describe what they thought cities would look like in the future, then animated the kid-rendered cities in pop-up book form. There's plenty of fantasy here, but these budding urbanists also have an eye for connected, sustainable, eco-friendly living. Check out the monorails running between buildings in Boscopolis, or the cars in Bright City that run on fallen leaves.
What would the world be like if we could build houses out of bacteria? For starters, the story of the Three Little Pigs might have ended very differently. But biomanufactured bricks, made of a mixture of sand and non-pathogenic bacteria, could also help house people in developing countries while saving almost 800 million tons of CO2 every year.
K.C., who writes the blog A Girl and Her Bike, is a girl with a bike. She's also a District of Columbia police officer. But the second part's not so obvious when she's riding on a Capital Bikeshare bike, out of uniform and just trying to get home from work. Which is probably why some jackasses stopped behind her at a red light decided it would be fun to bump her bike with their car. At very least, they probably thought it wouldn't get them arrested. Suckers! Instead, the bumper bump turned the Girl on a Bike into a Pissed-Off Police …
The Environmental Working Group has released an updated list of the Dirty Dozen, the fruits and vegetables with the worst pesticide levels. Drumroll please: Apples Celery Strawberries Peaches Spinach Nectarines (imported) Grapes (imported) Sweet bell peppers Potatoes Blueberries (domestic) Lettuce Kale/collard greens If you can, it's worth shelling out a little extra for the organic versions of these. You can offset it by pinching your pennies on the Clean Fifteen, the produce with the lowest pesticide levels: Onions Sweet Corn Pineapples Avocado Asparagus Sweet peas Mangoes Eggplant Cantaloupe (domestic) Kiwi Cabbage Watermelon Sweet potatoes Grapefruit Mushrooms
Need at-a-glance visual evidence of that "scientific consensus on climate change" we keep talking about? Skeptical Science has put together an interactive visualization of 4,000 peer-reviewed climate science papers. You can drag the year slider around to see how research changes over time. And it gets even more interactive! The site also lets you see information about the papers, or in some cases the papers themselves — here's the first one indexed, from 1836. Plus, you can contribute to making the crowd-sourced project more comprehensive by adding links to papers you encounter. (The whole thing is still in development, and …
