It's really equally about the sun's pull, btw. They're saying that weather changes correlate with moon phases--which are global--and not just due to the local, twice-daily lunar tidal effect. The alignments of sun + moon cause the moon phases (independent of the earth's daily rotation), and it only seems to be more of a moon than sun thing because the moon phase is such an obvious visual cue. (Ha, I'm having a hard time explaining this!)

If the correlation between moon phase and weather is only 1% or 2% at most, then it's hardly even worth knowing about (in terms of predicting local weather). How my girlfriend(s) and I felt during a full moon in the park and the fact that my dog howls at it tell me that the psychological effect of phases is even more interesting. :)

I know this article is couple of years old, but I still think it is very cool.

Calculating the speed of light at home

If we'd been allowed to go to the girls' school* to do physics experiments like this I'd probably be a science geek instead of IT.

*I went to a single-sex high school. The boys' school didn't have kitchens at the time so any 'sissies' had to go to the girls' college for home economics. I always wondered what was 'sissy' about being one of the only boys available to 1500 girls.

Adriana, on the censoring of science, see this piece today on PZ Myers's blog:

http://scienceblogs.com/pharyngula/2010/09/gagging_the_mississippi....

Scientists these days are having a hard enough time communicating the truth about sensitive (anti-corporate interest) issues without this kind of thing. In academia, no less!

California Academy of Sciences: Human Evolution -- Tool use by early humans started much earlier. The Academy's Zeray Alemseged reveals his latest discovery: human stone tool use dating back to 3.4 million years ago. Small-brained human ancestors used stone tools to whack into large mammals some 800,000 years earlier than previously thought.

- The earliest known evidence for stone tool use and meat eating among early humans is found.
- The evidence -- butchered, fossilized bones -- dates to roughly 3.4 million years ago.
- It's believed the ancestor Australopithecus afarensis (to which "Lucy" belongs) used the tools.

BBC News: Tool-making and meat-eating began 3.5 million years ago
Researchers have found evidence that hominins - early human ancestors
used stone tools to cleave meat from animal bones more than 3.2 million years ago. That pushes back the earliest known tool use and meat-eating in such hominins by more than 800,000 years.

Bones found in Ethiopia show cuts from stone and indications that the bones were forcibly broken to remove marrow. The research, in the journal Nature, challenges several notions about our ancestors' behaviour.

Previously the oldest-known use of stone tools came from the nearby Gona region of Ethiopia, dating back to about 2.5 million years ago. That suggests that it was our more direct ancestors, members of our own genus Homo, that were the first to use tools.

But the marked bones were found in the Dikika region, with their age determined by dating the nearby volcanic rock -- to between 3.2 million and 3.4 million years ago.

A battery of tests showed that the cuts, scrapes and scratches were made before the bones fossilised, and detailed analysis even showed that there were bits of stone lodged in one of the cuts.

Did Our Ancestors Practice Cannibalism?
By Margaret Aprison
Posted September 2, 2010
Moments of Science

Cannibalism may seem like a completely out of the ordinary practice today. Yet, scientists have discovered evidence that over one million years ago, our ancestors may have been cannibals.

Discovering Bones
A team, led by archaeologist Eudald Carbonell of Spain’s University of Rovira and Virgil, examined ancient bones left in a Spanish cave.

The bones had cut marks and butchering remains on them. This suggests that cannibalism could have been a popular activity.

Who Were Our Ancestors?
Scientists have learned that our “archaic” human ancestors, also known as Homo antecessor, possessed a brain two-thirds the size of modern humans.

The bones also suggest that cannibalism may have been just another way our ancestors stayed alive during famines. The study’s author suggests that this is one of the oldest documented cases of cannibalism.

Adriana: 17 years ago the doctors told me I had one year to live. I took that as a warning and didn't change a thing.

From Jerry Coyne's site:

Good news! According to a comment on Pharyngula, P.Z. has a new stent and is going home tomorrow.

Says the PeeZee, “I’m no longer sick,

Thanks to a spiffy new medical trick:

My aorta’s not bent

For I haz a new stent—

Now I’ll go back to being a dick!”
