esiegel | June 4, 2012"Life exists in the universe only because the carbon atom possesses certain exceptional properties." -James Jeans
Here on Earth, every living thing is based around four fundamental, elemental building blocks of life: hydrogen, oxygen, nitrogen and, perhaps most importantly, carbon.

From diamonds to nanotubes to DNA, carbon is indispensable for constructing practically all of the most intricate structures we know of. Most of the carbon in our world comes from long-dead stars, in the form of Carbon-12: carbon atoms containing six…
gregladen | February 26, 2011How old is the earth?
Short answer: 4,540,000,00/H30 Earth-years, plus or minus 1%.
Long answer: We don't know exactly because direct dating of the earliest material on the surface of the Earth will only tell use a minimum age; Prior to that, the Earth's surface was probably molten, and even after that, it may be that the earliest non-molten material has been recycled into the planet's interior by tectonic processes. Also, the earth is a big round ball of stuff that condensed into this shape from part of a large disk-shaped blob of stuff known as the Solar Nebula. When exactly, given this,…

In the OkCupid post on response rates and race & sex there are two charts which show how males and females respond to inquiries of the opposite sex by race. So, you can see that black women on OkCupid respond positively to men in general, while women respond positively in particular to white men. In fact for many racial minorities women respond more positively to inquiries from white men than they do co-racialists (the same is not true of men). I suspect some of this has to do with the excess of men on OkCupid, combined with selection effects in terms of who joins OkCupid. OkCupid is…
razib | October 13, 2009It's been a few weeks, but I thought I would point you to an interesting post on OkCupid's blog about race and dating. They report an interesting trend of preference for white men among all groups of females, as well as lots of other interesting nuggets. Of course, as many have noted the core demographic of OkCupid is a bit different than the general population, and might be especially so when it comes to racial minorities. I did think though that the stated racial preferences of the sample are interesting in light of other data which suggest women are more racialist than men.
In all classes…
grrlscientist | June 22, 2009tags: What's Wrong with Philip, comedy, humor, funny, streaming video
This video is a touching vignette about the difficult moment where a woman breaks up with her beau, Philip. As you'll notice in this video, Philip suffers from a common problem: he doesn't listen. However, that said, I sure wish I had a Philip to deal with my parents and family .. although I could do without his farting [2:45]

cwilcox | January 18, 2009The estrogen hormone oestradiol is associated with just about every aspect of female beauty. As well as serving as a growth hormone for female reproductive organs, it's associated with having a symmetrical face, large breasts and a low waist-to-hip ratio. Now, the hormone is credited with one more association: it makes women serial monogamists.
Her relationships explainedby her body cheimstry?
For those who may not have heard of this term, let me explain. A serial monogamist is a person who has sequential relationships, and who tends not to spend much time alone in between partners. While…
esiegel | April 24, 2008Even creationists have said that if you find something that's alive now that's over 6000 years old, it would prove to them that the Earth is at least that old.
Previously, the oldest tree in the world was thought to be a Bristlecone Pine in California, known as the Methuselah tree, at 4,840 years old (as of 2008).
It's huge! But you can also date a tree not by its trunk, but by its root structure. And as The Log Blog reports, Swedish researchers have found a tree on Fulu Mountain that is over 9,000 years old! Although it looks puny because its trunk dies every few hundred years or so and it…
sb admin | September 5, 2007I haven't read the study— it would take some digging to find, after all!— only the CNN Article, but the title sums up half of the results: "Men want hot women, study confirms."
In a nutshell, the study found that in a speed-dating test, men, despite what they said they were looking for, almost always went for the most physically attractive women (measured I am not sure how). Women, meanwhile, went for a man whose "desirability" (again, measured I am not sure how) matched their own assessment of how attractive they are.
The conclusion the article claims is that humans, despite high-minded…
