Interesting Stuff: Early December 2009

I’m preparing a quiz on the history of science since 1950, for use at my Dad’s 60th birthday. Here are some links to useful timelines I found: [1, 2, 3, 4, 5].

(These sometimes contradict each other, but of course, when assembling a trivia quiz it’s vital to seek independent verification.)

And now, the rest of my links for this installment.

Astronomy:

  • A study of rocks that Jupiter protects us from and what rocks it only makes more dangerous.
  • Evidence that quasars can help stars to form.
  • Explaining the asymmetry of lakes on Titan.
  • Speculation that super earths might be more suitable for life than Earth.

Biology:

  • In Australia we’re used to the idea of foreign species invading us, but not to the idea that our species might do the invading. Redback spiders in Japan are an exception.
  • Humans inadvertently split one species of bird into two groups.
  • Confirmation that proteins traverse DNA helically.
  • Amputee controls robotic hand as his own.

    Found the redback story fascinating. Given our history of invasions, it’s surprisingly difficult to imagine Aussie species getting a foothold elsewhere, isn’t it?

    Yeah, I think I’ve heard something about certain Australian trees becoming weeds in parts of America, but other than that I can’t think of any more examples.
