Dogs curl their tongue under to form a ladle:

YouTube - Time Warp - Dog Drinking

On the same (Discovery) show that clip is from, they made one of the cameramen lap water, for comic contrast, and replayed it in slow motion. It was pretty funny: our tongues are relatively rigid and slow, so the best we can do is 'flick' the water foreward and (inadequately) upward, in big messy heaves--kinda like using a spade--with the result that most of it winds up in the nose rather than the mouth.

I hope this freaks people the fuck out more about climate change, although it's probably irreversible at this point.

Scientists capture antimatter atoms in particle breakthrough - CNN

Scientists have captured antimatter atoms for the first time, a breakthrough that could eventually help us to understand the nature and origins of the universe.

Researchers at CERN, the Geneva-based particle physics laboratory, have managed to confine single antihydrogen atoms in a magnetic trap.

This will allow them to conduct a more detailed study of antihydrogen, which will in turn allow scientists to compare matter and antimatter.

Understanding antimatter is one of the biggest challenges facing science -- most theoretical physicists and cosmologists believe that at the Big Bang, when the universe was created, matter and antimatter were produced in equal amounts.

NASA press conference tomorrow:
NASA Astrobiology Press Conference: Have They Made Breakthrough In Search For Extraterrestrial Life?

Has NASA made a breakthrough in the search extraterrestrial life? That's what some are speculating after NASA sent out a curious press release announcing a news conference on Thursday, Dec. 2, to discuss an "astrobiology finding that will impact the search for evidence of extraterrestrial life."

(Not that the agency has ever been politicized but timing an interesting discovery certainly would help them when it comes to the inevitable budget slashing that is at hand in the government.)

That's it.

NASA - NASA-Funded Research Discovers Life Built With Toxic Chemical

Researchers conducting tests in the harsh environment of Mono Lake in California have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism substitutes arsenic for phosphorus in its cell components.

"We know that some microbes can breathe arsenic, but what we've found is a microbe doing something new -- building parts of itself out of arsenic," said Felisa Wolfe-Simon, a NASA Astrobiology Research Fellow in residence at the U.S. Geological Survey in Menlo Park, Calif., and the research team's lead scientist. "If something here on Earth can do something so unexpected, what else can life do that we haven't seen yet?"

However, I wouldn't mind having one of those.

If you don't want to be replaced by a robot, then don't act like a robot !

The title may be a bit misleading. This is just electrolysis.

YouTube - Science experiment:Homemade hydrogen fuel

We tried it once back in school. Used a 12V power source and also kept container covered for about 15 minutes. And with an elaborate mechanism to drop a piece of burning paper into it, we achieved a pretty decent explosion.

My brother and I used to do that growing up. Lots of fun. Amazingly, neither of us ever got hurt.

I found a toy rocket kit that uses electrolyzed water (obviously hydrogen) as its fuel. I should dig that out and try it.

[Just_Boy]

^ Yeah, great fun. The hardest part was to learn the art of taking out those pencil leads. coz here we use pens right from kindergarten.

My cousin had one of those toy rockets. But it was not that simple. It required citric acid crystals for the hydrogen generator to work and the electronics in the ignition system were pretty complex.

I think it's funny that my mom never questioned how many big, 12V lantern batteries we went through. If we could have gotten a car battery we would have, but then we'd have been exposed.
