PNAS Lexus lane? 46,000 hits!
In 2007, scientists proposed that the start of the Younger Dryas (YD) chronozone (10,900 radiocarbon years ago) and late Pleistocene extinctions resulted from the explosion of a comet in the […]
It is safe to say The Bos is becoming obsessed. Someone please count and let me know, but I believe he has four publications this year seeking to undermine the Younger Dryas Boundary Hypothesis. Over time he has published more than a dozen. Today he is back in PNAS — alone — […]

Where Lies the Younger Dryas Boundary Smoking Gun?
Nice sum up from a creationist blog

To a great degree the Tusk itself was a response to my frustration with Todd Surovell and Vance Holliday’s botched 2009 PNAS journal article, “An independent evaluation of the Younger Dryas extraterrestrial impact hypothesis,” published three months before this blog began.
Despite my early understanding of the sloppy work of the authors, however, I did […]

This appears to be the long hoped for independent, intentional, blind, professional and reproducible confirmation of the original 2007 findings of the Younger Dryas Boundary team.
Independent evaluation of conflicting microspherule results from different investigations of the Younger Dryas […]
I came across a well-researched and informative blog today summing up the recent findings and YDB science to date. I was so impressed by Abby Tabor’s post at Science Works Now, “New Evidence for Climate-Changing Cosmic Impact,” I have added a permanent link to her on the side-bar.
Tabor it seems was driven — shudder […]
These scientists have identified three contemporaneous levels more than 12,000 years ago, on two continents yielding siliceous scoria-like objects (SLO’s),” said H. Richard Lane, program director of National Science Foundation’s Division of Earth Sciences, which funded the research. “SLO’s are indicative of high-energy cosmic airbursts/impacts, bolstering the contention that these events induced […]

Distinguished Science writer Dr. Richard Kerr walked the plank this afternoon in response to this morning’s Knight Science Journalism Tracker inquiry of science writers.
Charles Petit’s casual post brought quick attention from the old-school dean of science writing. Kerr implored his press colleagues to, in effect: Move on, move on…There is nothing […]
