Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

This is Scientific American's 60-second science. I'm Christopher in Taliatta.

If you've ever watched a moth flutter clumsily around a light on your porch, the insect might

seem like a sad match for a predatory bat. The flying mammal is practically a fighter jet in

comparison, with its sophisticated sonar and acrobatic maneuvers. But some moth species have evolved high-tech tricks of their own.

For example, their wings have long dangling tails.

So that they're fluttering in space and they're twisting behind the moth as the moth flies,

creating an alternative echoic target that the bat perceives as a target that it can actually attack.

Rubin and her team investigated that phenomenon by experimentally altering the wings of moths.

With some moths, they snip the hind wing lobes and tails.

With other moths, they glued on extra bits of wing.

And then they tethered the differently shaped moths, one at a time, in a padded,

darkened chamber, a sort of claditorial ring for bats on the hunt, and observed the battle with

high-speed video and ultrasonic microphones. By the way, that echo-locating sound has been

slowed down ten times so we can hear it.

Turns out it was the moths with longer hind wings or wing tails that lived to fly another day because the bats often wound up with just a mouthful of tail.

And of course these tail ends do not have a nutritional value essentially

and would not be a wise place for the bat to attack if it really
