New Evidence Presented For Ancient Fossils In Mars Rocks 91

azoblue passes along a story in the Washington Post, which begins: "NASA's Mars Meteorite Research Team reopened a 14-year-old controversy on extraterrestrial life last week, reaffirming and offering support for its widely challenged assertion that a 4-billion-year-old meteorite that landed thousands of years ago on Antarctica shows evidence of microscopic life on Mars. In addition to presenting research that they said disproved some of their critics, the scientists reported that additional Martian meteorites appear to house distinct and identifiable microbial fossils that point even more strongly to the existence of life. 'We feel more confident than ever that Mars probably once was, and maybe still is, home to life,' team leader David McKay said at a NASA-sponsored conference on astrobiology."

Sorry, but I think you and many of the others here need to go back and read his question. He didn't say he wanted ideas for labs, he said he wanted his students to contribute to real science, as in, do things that lead to publications by professional physicists. While I did many of the experiments that you did and found them interesting and learned a lot from them, none of those produced publishable results. You made fun of Galaxy Zoo, but the work that the thousands of people did who participated in that experiment led to real publications in the astronomical literature. Astronomy in particular is a science where amateurs can contribute and I think he cited Galaxy Zoo not because he thought it was better than building a Foucault Pendulum, but because it has a different goal -- it is getting his students to put in their time as essentially free labor on science projects much larger than they could do in class. Although, maybe you know of a high school building a 3.5 meter telescope with a drift scan camera and multi-object spectrograph that is recording images and spectra for a million galaxies. Because at that school, kids could get the same experience the ones in his class got by participating in Galaxy Zoo.

Apple may be cutting corners in QA in response to the lower premiums they've been able to charge over the years.

I've had hardware problems with a PBook G4 17", an iMac G5, and an older iBook. When I mentioned this to my local Apple Service guy, he told me that he's noticed that as Apple has come down in price, they've been forced to use less expensive components with correspondingly higher failure rates.

True or not, I agree with another poster who pointed out they've been much more responsive to these issues. I had all three fixed for free, even post AppleCare warranty period.

Hackers of the world, unite!
