Thanksgiving is almost here and, perhaps, you're planning to brave the deep fryer.

You've got the oil. You've got the pan. You've got the fire. You should be good to go, right?

But, how do you know the oil is ready?

Researchers in the field of fluid dynamics have a trick – use your ears.

The scientists were inspired by a classic kitchen hack, used to test tempura-frying oil. You wet the pointy end of a wooden chopstick, stick it into the oil, and listen.

Scientists have found something strange has been happening among sensitive bird species in the Brazilian Amazon in recent years.

Not only were the birds declining in number, but their bodies were also shrinking in size.

"We found that size is not only shrinking for those sensitive species — it was declining for everyone," said researcher Vitek Jirinec of Louisiana State University.

Jirinec's findings are contained in a new study published in the journal Science Advances last Friday.
