Welcome to Breakthroughs with Pfizer UK, the podcast where Pfizer invites experts from across the pharmaceutical industry to discuss the most pressing healthcare topics.

Approximately 5% of the red disease is estimated to be about 7,000 that exist. Only 5% of them have treatments.

Because of the really small patient numbers, you can't have your giant trials that give shoes statistical power.

This is Scientific Americans, 60-Second Science. I'm Karen Hopkins.

Some things are so adorable. We say they're cute as a bug's ear. Of course, bugs don't have ears.

But a new study shows that orb-weaving spiders can use their webs to detect sounds.

The findings are unfurled in the proceedings of the National Academy of Sciences.

Any animal that makes sounds is likely to have an ear.

Ron Hoy studies neurobiology and behavior at Cornell University in Ithaca.

Ranging all the way from tiny crickets and flies that are even smarter than crickets all the way through to humans, of course.

It's also pretty interesting that great many animals don't have ear drums, but they still hear.

That's Ron Miles. The two Ron's here.

Ron Miles, who's been collaborating with Ron Hoy for 30 years, is an engineer at Binghamton University.

Critters lacking ear drums receive audio input via very fine hairs.

If you look at many insects and spiders are covered with hairs.

Because these whispy little filaments can float freely in the breeze, they're great at sensing the air currents that comprise sound waves.

We were kind of wondering, you know, how would you make something that could sense sound the way some of these small animals do?

A possibility appeared during an afternoon stroll.

So my graduate student, Jen Zo, he was walking in our campus nature reserve one day.

And he noticed that when the wind blew, if you look at a spider web, it moves with the wind.
