Science Daily reports on an interesting new application of Radiocarbon dating:
From the end of World War II and up until about 1960, the superpowers of the Cold War era, conducted nuclear tests, detonating bombs into the atmosphere. These detonations have affected the content of radioactive trace materials in the air and created what scientists refer to as the C-14 bomb pulse. From the first nuclear detonation and, until the ban on nuclear testing was evoked, the quantity of C-14 in the atmosphere doubled. Since 1960, it has only slowly decreased to natural levels.
This sudden curve has left an impression in the food chain and therefore also in the lens crystallins of the eyes, which have absorbed the increased carbon content through food stuffs. Since the crystallins remain unchanged once they have been created, they reflect the content of C-14 present in the atmosphere at the time of their creation. An event occurring shortly after birth. Using a large nuclear accelerator, physicists at Aarhus University can now determine the amount of C-14 in as little as one milligram of lens tissue and thereby calculate the year of birth.
The research behind the article appears in PLoS ONE (A wag of the finger to Coturnix for not giving me a heads up on this). I haven’t read the PLoS paper yet so I won’t comment further.

Vol 33 of the Four Stone Hearth is up at Greg Laden’s Blog. There was an excellent turn out by the anthropology blogosphere. Check it out!

I have made a guest appearance at Orac’s blog along with ERV and Bad. I’m just hoping we are not all redshirts…

The more things change the more they stay the same. I mention this because I was perusing a book on creationism published in 1876. The book was written by Thomas Wharton Jones and is called Evolution Of The Human Race From Apes and Of Apes From Lower Animals A Doctrine Unsanctioned By Science. The quote below is from the “advertisement”:

Channeling Mel Gibson in Mad Max Luskin goes into attack Pinto mode, unfortunately his intended victim is a friend of ERV’s. ERV is not happy. As an afterthought, although the DI types don’t like, say, PZ and Wesley and some of the other Panda’s Thumbites they really save their scorn for Eugenie Scott and, to an even greater extent, Barbara Forest. Based on her output in the last year, I fully expect ERV to join that illustrious company in the near future, and I hasten to add, that is great company to be in. Maybe the NCSE should recruit her.

Well, it’s not really a contest because there are no prizes other than an honorable mention on my sidebar – next to Pough. I’m not planning on replacing my banners, but I would like to add several more to the rotation (I’m thinking three). Since I’m not very proficient at Photoshop, I thought I would throw myself on the mercy of my readers and ask you to design me some new banners. They should be 756 x 93 pixels max. They should also be appropriate for an anthropology blog and have “afarensis: Anthropology, Evolution, and Science” somewhere on them. You can email them to me at:
The minor blog change consists of me moving my blogroll, which was getting quite long, to a tab at the top of my blog.

I don’t know how I missed this, but National Geographic has an interesting article concerning archaeological excavations at Mt. Lykaion – one of the birthplaces of Zeus (the other being Mt. Ida in Crete, but we know what Epimenides thought of the Cretans). According to the article, excavations reveal that sacrifices took place at Mt. Lykaion a full 1,000 years before Zeus made an appearance:
