Here are a few items that have caught my (and NeuWrite member Sammy Katta's) eye on the interwebs in the last week and a half.
To start us off, the bright world of ethology-based science.
The Sloth's Busy Inner Life
Over at the NY Times, an article covering recent research on why sloth's come down from their trees to defecate. Previously, the proposed reason was because they were attempting to fertilize the tree they live in. The new hypothesis: so that the hundreds of moths that live in their fur can lay their eggs. Having a large resident moth population is critical for the sloth, because when the moths die, their bodies (and the nitrogen byproduct of decomposition) feed the algae that also inhabit the sloths fur. And the sloths eat the algae, to supplement their nutrition-poor leaf diet.
So sloths = algae farmers. Awesome.

Second, from the always entertaining Ed Yong, a story of 2 Southern Pacific rattlesnake populations. These groups, located 2 hours away from each other, use radically different venom strategies: one population uses haemotoxic venom, and the other uses neurotoxic venom.

Now that I've cheered you up, something depressing.
A wild misogynist is spotted ... writing a Nature Editorial
For the story, I'll leave you in the capable hands of Kelly Hills (@rocza):
And for a follow-up, Hope Jahren (@HopeJahren) discusses her decision to turn down a scheduled Q&A with Nature Magazine, following the publication of the editorial in question.
On a less unimaginably frustrating note...
Egg shells - stronger than you think.

The GMO Debate
Panic-Free GMOs, over at Grist.org
[A] really excellent series covering the sources of disconnects between the various sides of the GMO debate. There's a whole lot of articles, but I recommend reading at least a few (regardless of which side you fall on) to get some insight into why the other side might think as they do.
The most recent post, as of last week, does a good job of capturing the heart of the reason this controversy continues to turn people against each other. It's actually very applicable to people on both sides of most of these kinds of controversies, and if you take a moment to think about it, you might find it applies to you too.
