A meteor or comet impact near Quebec heaved a rain of hot melted rock along North America’s Atlantic Coast about 12,900 years ago, a new study claims.
Scientists have traced the geochemical signature of the BB-sized spherules that rained down back to their source, the 1.5-billion-year-old Quebecia terrane in northeastern Canada near the Gulf [...]

Surovell, et. al 2009 has another serious challenge here.
Challengers to Clovis-age impact theory missed key protocols, new study finds
EUGENE, Ore. — (Sept. 18, 2012) — An interdisciplinary team of scientists from seven U.S. institutions says a disregard of [...]

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 to see here.
Well, well. A cat just leapt from the bag.
I don’t have an “as published” copy yet (despite being a co-author). But I will post one just as soon as I do.
