Ironically, use of this device might actually be leaving the user more prone to disease. Constant low-level of exposure to pathogens keeps the immune system primed. (Know any nurses? Ever see them down with a cold or flu?)

Unlike a mule, Big Dog follows directions to the letter, and can keep slogging along, non-stop, for as long as its fuel supply lasts. You'll notice at the end of the video where Big Dog was jumping across the yellow-bordered region, how precisely it placed its legs on landing. Further refinement may enable bots that are far more nimble than their slower carbon-based friends.

It could have acquired that much energy by being picked up in the tread of a semi or wedged between two tires, then flicked free at the radial velocity of the tire. A hunk of steel thrown at 80 mph might easily puncture a quarter-panel, especially if it's one of those mostly-plastic ones. It could have gained additional velocity if it had an elastic collision with another tire or sufficiently elastic surface traveling opposite it before hitting their quarter-panel.

I once worked in a building that was about 50 meters from an interstate highway. One morning, one of the developers found his window smashed and a rock the size of a chicken egg embedded in his wall. It was attributed to a semi having flung it.

I love kimchee too, but I have to wonder at the wisdom of consuming a vegetable somewhat famous for generating, um, "methane" in an enclosed environment. Seems like it might be a fire hazard, among other things.

I think they're misinterpreting the 'emotion' being felt. When I score a kill, I get a boost of aggression, spurring me on to the next kill. When I'm killed, I immediately relax, and am often surprised at how many muscle groups I had unconsciously tensed. Also, depending on how I was killed, I may mutter unprintable things about the person who just knifed me in the back or who was camping my spawn point.

Hmmm...until lately, we've all been perfectly content to simply roll the dice and accept random mutations as our method of coming up with useful new plants. No guarantees that a random mutation doesn't make a previously innocuous protein into a slow poison or carcinogen.

Now that we're able to work deterministically, at the level of the individual nuts and bolts of DNA, to incorporate tried-and-true desirable features from other species, folks are suddenly getting skittish? What's up with that?

One reason you're not allowed to run whatever you wish on hardware you believe you've purchased is that you didn't pay for all of it, so it isn't entirely yours. Game consoles are sold at a loss, to make them affordable for consumers. The games are more expensive than their PC counterpart, in part to subsidize the cheap console hardware, and in part to pay for the royalty paid by the software maker to the console maker for the privilege of selling to the market the console maker has created. By subverting the protection, users are increasing the risk that the console maker will be unable to recover the cash they risked by selling consoles at a loss. (But I'd bet a nickel Nintendo has made out okay on the Wii).

As others have pointed out, lard is not as unhealthy for you as, say, butter or margarine, and has about the same number of calories. Moreover, if you saute onions in some lard, then strain it into a suitable container and let it congeal, it makes a heavenly spread for crusty bread.

Also, BHA and propyl gallate appear to be far less carcinogenic than, say, peanut butter, basil or black pepper. See: http://potency.berkeley.edu/chempages/PROPYL%20GALLATE.html

Hmmm... But how many of those remaining days are likely to be useful toward his projects? As I finish my 50th lap around the sun, I'm already feeling the subtle, inevitable waning of ability that comes from old-age disease. Realistically, I suspect Mr. Kelly has only about 2000 days of fully useful days, followed by 6500 days of increasingly non-functional dotage.
