Everybody poops, including panda bears. (See about 0:35 in the above video for evidence.) But panda poop could turn out to be quite a bit more important than your average animal excrement. That's because scientists are "mining" it for bacteria that could help make better biofuel.
The key problem with biofuel today is that the stuff that's actually economical to produce — i.e., corn ethanol — isn't really that great for the environment. Corn farming uses a lot of fertilizer, water, and herbicide. Using corn that was previously grown for food to make fuel, instead, can lead to deforestation as people clear land to make up for the lost food farming. Some models of carbon dioxide emissions suggest that, by the time you factor in things like fossil-fuel derived fertilizers and the deforestation, a gallon of corn ethanol might not be any better for climate change than a gallon of gasoline. Not all the models agree on that. But even if corn ethanol produces fewer carbon emissions than gas, you still have to deal with the fact that growing nutrient-hungry corn on the same patch of ground over and over and over is really bad for local soil and water quality.
Cellulosic ethanol could be a much better alternative — particularly cellulosic ethanol made from native, perennial plants that don't require heavy inputs to thrive and actually improve the health of the land they're grown on. The problem: Converting those plants into fuel is, so far, a lot more expensive. Cellulose — the plant fiber that makes up things like stalks of bamboo and tall prairie grasses — is tough stuff and hard to break down.
That's where panda poop comes in. Pandas process tons of cellulose every day, right in their guts. Maybe the bacteria that work for them could work for us, too.

Fascinating, now gimme a double latte. (AsapSCIENCE)
Since its publication in late 2015, science writer Oliver Morton’s The Planet Remade: How Geoengineering Could Change the World has swept many “best book” (best science book, best business book, best nonfiction book) and with good reason: though it weighs in at a hefty 440 pages and covers a broad scientific, political and technological territory, few science books are more important, timely and beautifully written.
After years of speculation and wrangling over his remains, Kennewick Man turns out to be closely related to contemporary, local Native Americans after all. Discovered near Kennewick, Wash., in 1996, the skeleton ended up in a tug of war between tribes in the pacific northwest who wanted to bury the remains, and scientists who wanted […]
White hat hackers get paid to find holes in their own employers’ online systems, and plug those holes before they become serious security risks. It’s a job that pays handsomely…mostly because few job candidates, even experienced IT professionals, have the skills to scamper over firewalls and infiltrate the deepest recesses of a battle-tested network. But […]
Why buy one of those expensive and confusing universal remotes, clogged with enough buttons to launch a space shuttle, when you could accomplish the same electronic control right on your favorite mobile device? The Blumoo Universal Remote, now just $52.99 in the Boing Boing Store, harnesses the audio power of all your household equipment right […]
You may not love Microsoft Word, but you’ve definitely used it. Other than being one of the most ubiquitous programs on the planet, it’s been the go-to word processing system for more than a quarter-century because it’s as basic as it gets. But occasionally, you’ve got assignments that beg for a lot more options than simple […]
