Science News questions science

July 12, 2018

I was about ten when my mom bought a Science News subscription for the Tusk. Week after week the thin, frequent, small format publication filled my desk, and ultimately the floor of my room.

Chandra Wickramasinghe on the NASA Mars announcement

Panspermia increasingly vindicated

June 7, 2018

The Tusk is honored to maintain a digital acquaintance with distinguished Professor Chandra Wickramasinghe, who in the 1970’s with Sir Fred Hoyle established — and to my mind proved — the theory of Panspermia.

Tusk on Seven Ages Podcast

Seven Ages Audio Journal

May 20, 2018

I had a blast last week joining the hosts of my favorite new podcast: Seven Ages Audio Journal. Like the Tusk, veteran podcaster Micah Hanks and his science bros Jason Pentrail and James Waldo attempt the difficult balance between hard science, responsible speculation and perhaps some entertainment. I think they recognized me as a “fellow […]

The Tusk enjoyed that paper and was pleased to see Sweatman make a second contribution to our field; this […]

Black Mat in Turkey

Asia

March 23, 2018

This week Rick Firestone shared a little known 2009 paper with the Tusk and some others. I was unaware of it and enjoyed reading it. The authors find a unique spike in fire at Akgol, Turkey ~13,000 years ago which they attribute to a horrendous inferno in a marsh, of all places. They cite Firestone […]
