More people on the East Coast are acquiring a taste for snakehead, an exotic fish that's moved here from Asia. But the fish are still multiplying and spreading.
Snakehead came to Maryland almost 10 years ago. The so-called "Frankenfish" looks like its namesake and has multiple rows of teeth. Someone released it here — and then there was a documentary and an unbelievably bad movie.
I'm standing in the Manhattan office of Andrew Farnsworth, a research associate at Cornell University's ornithology lab. Farnsworth is using meteorological data, radar data, crowd-sourced eBird data and acoustic data from the flight calls of migrating birds to predict where birds are going and when they'll be there.
Fossil-hunting scientists are coming to grips with a new discovery that could change forever how we think of dinosaurs. What they've found is that dinosaurs may well have been tortured by large, flealike bloodsucking insects.
Yes, it appears that the greatest predators that ever roamed Earth suffered just as we mammals did — and as we still do. Fleas were thought to have evolved along with mammals — they like our soft skins and a diet of warm blood.
