A masterful and comprehensive effort here from respected Comet Research Group co-author, Bill Mahaney. Much of the discipline-specific text is hard for the Tusk to fully grasp, and I have had no time to properly review, but I have asked Bill to provide a layman's summary of...

Last month a little noted but fascinating journal article was published providing empirical, genetic evidence for a central claim of the Comet Research Group since 2007: A dramatic loss of life due to the rain of comet fragments.

The Tusk had one of those "Holy Moley!" moments with the Younger Dryas Impact Hypothesis this weekend. Not a new paper, or even an entire show on a global communication platform, but rather a massive compilation of hard data on the YDIH -- and associated analysis framework --...

As the Taurid meteor season wanes on the approach of Thanksgiving, I thought it was relevant (and economical) to share a couple of recent videos which present the Taurid phenomena from different, but mutually informative contexts. The first is a ‘live shot,’ and the second is...

In wake of Halloween last week a very, very scary scientific paper was published. "Widespread glasses generated by cometary fireballs during the late Pleistocene in the Atacama Desert, Chile," creates a rebuttable presumption that horrific cosmic airbursts -- without leaving...

A comprehensive study of the Taurid meteor stream released last week confirms a central understanding of astronomer Dr. Bill Napier and the Comet Research Group, one which was incorporated into the YDI hypothesis from the start. From Discover Magazine: The longest-studied...

It has been proposed that the Younger Dryas period/GS-1 was initiated by a cosmic impact, for which there is indirect and debated evidence in a large number of sites in the NH surrounding the North Atlantic region (Kennett et al., 2015). A very significant Platinum (Pt) spike...

The Tusk recalls keeping the YDIE a secret in 2006 and 2007, so as not to threaten the publication of what became the seminal paper in 2007. Today the secret is most assuredly OUT. Hundreds of hours of podcasts, videos, and plain old lectures are spilling forth from people...

An extensively covered journal article by Sun et al. in Science Advances concludes that volcanoes -- not a fragmenting comet -- caused the Younger Dryas. Sun provides an invaluable trove of data, but less than 72 hours after the publication their interpretation is suffering.
