OTD in 1912, Alfred Wegener delivered a lecture propounding the theory that our modern continents were formed by the splitting and drifting apart of an ancient supercontinent, which he named Pangea.
Due to his failure to offer a plausible mechanism, he was widely ridiculed.

Great to see a natural history collection growing in an era when the expansion of barriers to such growth is inexorable.
Great news article about the Tulane University Biodiversity Research Institute's Royal D. Suttkus Fish Collection and our recent accessions of specimens from the DEEPEND Consortium and the University of Louisiana at Monroe.
There are 8 million fish in a World War II bunker outside New Orleans. More arrive soon.
Hidden in a World War II bunker near New Orleans, Tulane stores more than 8 million preserved fish — and the collection is still growing.

We are undergoing unprecedented loss of freshwater across the planet
Rising temperatures are causing water to evaporate and driving humans to extract more groundwater, which is moving freshwater from the land to the seas and creating a "continental drying" trend
