But the last one warning in Samsung’s list is starting to get more attention:

Viewing in 3D mode may cause disorientation for some viewers. DO NOT place your television near open stairwells, cables, balconies or other objects that may cause you to injure yourself.

Bionic feet for amputee cat – “A cat that had its back feet severed by a combine harvester has been given two prosthetic limbs in a pioneering operation by a UK vet. The new feet are custom-made implants that “peg” the ankle to the foot. They are bioengineered to mimic the way deer antler bone grows through the skin…”

Energy is ubiquitous, which makes it a beautiful blog topic. Once you start thinking about energy as more than just oil or solar power, but rather as the input that powers all systems, a world of topics opens up for you. If you’re like me, you also start thinking about all the ways in which energy is lost. You just lost some reading this. I just lost some writing this.

For an amputee, all that lost energy can add up. Consider that people without prosthetic limbs dissipate a significant amount of energy while walking, mainly between strides, according to Steven Collins and Arthur Kuo, the developers of a micro-processor-controlled artificial foot they described in a February 2010 PLoS ONE paper.

I don’t know about where you are, but things have been pretty sweltering here in Atlanta. It’s been so hot, in fact, that we decided to chill things off a bit with this week’s podcast topics.

First, how about a little cold, cold wine? And don’t worry — we’re not going to hit you with the typical wine-making science. That stuff’s all fascinating in its own right, but we decided to approach the topic from jazzier directions. In this podcast, you’ll learn what to expect at a neuroscientist‘s wine tasting, what varieties of super wines come from Chinese laboratories and we’ll even discuss a couple of wine-related mysteries that only science can solve.
