A new study suggests that the asteroid that killed the dinosaurs may have originated from the outer parts of the solar system. And, invasive spotted lanternflies often lay eggs on vehicles and shipped goods. Now researchers are training dogs to sniff them out before they hatch.
Asteroid That Killed The Dinosaurs Was A Carbon-Rich RockAround 66 million years ago, an asteroid slammed into the Earth, blasted debris everywhere, plummeted the planet into cold darkness, and ended the age of dinosaurs. (Though birds survived, of course.)
It might be the most famous disaster in our planet’s history, but scientists still have plenty of questions about it. Like, what was the asteroid made of? And where did it come from? A new study in the journal Science offers up some long-awaited answers.
Guest host Rachel Feltman speaks with study author Dr. Mario Fischer-Gödde, a geochemist at the University of Cologne in Germany.
Training Dogs To Stop The Spread Of Spotted LanternfliesIn 10 years, the spotted lanternfly has gone from non-existent in the U.S. to being established in at least 16 states. They’re quite distinct: The adults measure about an inch long, they’ve got striking red and black markings, and are, as the name suggests, spotted. And they’ve got a worrisome tendency to chow down on certain plants, including grapevines, and some fruit and hardwood trees.
Spotted lanternflies are able to spread so effectively in part because they tend to lay eggs on things that travel from state to state: shipping supplies, vehicles, and lumber.
There’s a new tactic to detect spotted lanternfly eggs before they can hatch: training dogs to sniff them out. Guest host Rachel Feltman speaks to two researchers behind this project: Dr. Nathan Hall, director of the Canine Olfaction Research and Education Laboratory at Texas Tech in Lubbock, and Dr. Erica Feuerbacher, associate professor of applied animal welfare and behavior at Virginia Tech in Blacksburg, Virginia.
