Were Hopewell people 2,000 years ago smarter than us? Experts debate on World Heritage Day The accomplishments of the Hopewell people who lived here and visited here more than 2,000 years ago beg the question, "Were they smarter than us?"

β€œThey worked in huge numbers completely cooperatively without an authoritarian leader. In that sense, they’re smarter than us because we haven’t figured out how to do that."

In the latest issue of the Journal of Ohio Archaeology, Rob Cook and I review the history of the amazing Serpent Mound, and address how this history has been ignored or distorted by people with varying agendas that are all tied to the racist Moundbuilder Myth.

Saturn Gains 128 New Moons, Bringing Its Total to 274 (Gift Article) The objects around the ringed planet are tiny, but some of them may have formed relatively recently in the solar system’s history.

"There may be even more moons around Saturn awaiting discovery, potentially in the thousands."

It seems like this situation is getting out of hand.

Science is political The value of scientists who are willing to speak out on political issues is only increasing

"Expecting scientists to refrain from political discourse ... undermines the societal impact of their work and neglects the ethical responsibilities inherent in their scientific endeavours."
