There's bad news for the Camembert and Bree lovers out there.

According to the French National Center for Scientific Research,

some of our beloved soft cheeses are at risk of extinction.

They're concerned that the microbial diversity needed to make these cheeses is dwindling

dramatically and therefore we may have trouble making them in the future.

It's Tuesday, February 20th, but,

mon Dieu! Today is Science Friday.

I'm Cyphrary producer Kathleen Davis.

As with many foods, consumers expect the cheese that they buy

to be consistent over time.

We want the brie that we buy today

to look and taste like the brie that we bought three months ago.

But there's a downside to this uniformity, and it's making it harder to create the cheeses that we know and love.

We'll get to that story in just a bit, but first what feathers can teach us about the evolution of flying dinosaurs.

Not all birds can fly. I'm looking at you penguins ostriches and kiwis. Now it's pretty easy to figure out if a living bird can fly, but what about extinct birds or say bird ancestors like dinosaurs?

Remember, all birds are dinosaurs, but not all dinosaurs evolved into birds.

So scientists wanted to figure out if there was a way to tell if a

dinosaur could fly or not. They found out that the number and symmetry of flight

feathers are reliable indicators of whether or not a bird or a dinosaur

could lift off the ground. Pretty interesting, isn't it? Joining me now to talk more about their

research and how it might help us better understand how

dinosaur flight evolved.
