Maybe you remember the old Far Side cartoon with two jellyfish outhouses featuring (apparently) identical icons on their doors, the caption reading "Only they know the difference." I was reminded of that strip reading this paper about two closely-related goby species. As the paper details, humans can face challenges differentiating them without genetic analysis. The most diagnostic visual difference only emerges once the fish reach a certain size, making the identity of smaller fish more ambiguous. Yet the genetic … [Read more...] about Science Corner: Only They Know the Difference

Greetings, future friends! I'm writing to you from the past, before Election Day in the United States. I hope you were all able to vote as you deemed appropriate, and you were able to do so safely.

To that end, we may benefit from a body of … [Read more...] about Science Corner: Party People

She had a passion for science and pursued her investigations without the kind of institutional support we associate with modern science. We may need more Mary Annings going forward as that kind of … [Read more...] about Science Corner: Digging into Natural History
