Can dogs be taught to help stop the spread of an invasive insect?

The dog is going to be sniffing at about 5 to 7 hurts, so that's breathing in and out 5 and 7 times within a second and that causes unique

airflow patterns. It's Thursday, September 5th and just like every day today is Science Friday. I'm Cyfry producer

Kathleen Davis. Spotted lantern flies are an invasive nuisance. They're quick

spreaders that love to chow down on certain plants, particularly fruit trees.

Scientists are training dogs to sniff out the eggs of these insects to help stop their spread.

We'll talk about that story in just a minute, but first

here's guest host Rachel feltman with new information on the asteroid that

killed the dinosaurs. Around 66 million years ago an asteroid slammed into the earth, spewed dust and rock everywhere,

plummeted the planet into cold darkness, and ended the age of dinosaurs. It might be the most famous natural 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.

Lead author Dr Mario Fisher Gouda is a geochemist at the University of Cologne in Germany.

Welcome to Science Friday.

Yeah, hi there, many thanks for having me.

So let's get into it.

Were you able to figure out what the asteroid was made of?

Yes, we definitely found an answer to this because we could show with our new study that

it was a carbonaceous type asteroid.

That's asteroids that formed further out in the solar system,

initially beyond the orbit of Jupiter.
