Waves come from the wind so tsunamis, which are basically bigger waves, must come from more wind, right? Not exactly. This cute animation explains that though normal waves are formed from above, tsunamis come from below from volcanic eruptions, landslides and earthquakes. They're the real monsters of the sea.
It may just be a Dodge ad celebrating 100 years of the company but, when 106-year-old Ethel Preston and her cronies look you in the eye and say you should do whatever the hell you want to do, you can tell they really mean it. Life is too damn short, even when you get to be one hundred years old. "Be a bad boy!" Indeed Ethel, indeed.
- Artificial human blood could be mass produced someday soon, providing a nearly limitless supply of type-O blood. This process could solve a lot of medical problems, but it could also bring out the vampires.... [url]
- The DNA laser printer can print custom strands of DNA -- to arbitrary lengths and with 100% accuracy. It doesn't quite match the sophistication of biological DNA synthesis, but being able to (cheaply!) create long stretches of custom DNA will make some biological studies a bit easier to do. [url]
- Surprisingly, it's not that difficult to obtain pluripotent stem cells from mice. Putting blood cells from a young mouse in a mildly acidic solution for about 30 minutes seems to do the trick -- but researchers are still trying to figure out exactly how this trick works so that they might be able to do it with adult human cells.
