0:00.0 | Understanding the human body is a team effort. That's where the Yachtel group comes in. |
0:05.8 | Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years. |
0:11.0 | Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program. |
0:19.6 | To learn more about Yachtolt, visit yawcp.co.j.jot.com.j. That's Y-A-K-U-L-T-C-O-J-P. |
0:28.4 | When it comes to a guide for your gut, count on Yacolt. |
0:33.7 | This is Scientific American's 60-second science. I'm Christopher in Taliatta. Got a minute? |
0:39.5 | Ten years ago, a bacterial disease began to eat away at the Florida citrus crop. It's called |
0:44.8 | Huang Longbing, or citrus greening, and it causes misshapen bitter green fruits, and eventually |
0:50.7 | dead trees. Since 2005, the infections estimated to have caused billions of dollars in damage. |
0:57.4 | And the microbe did all that damage with the unwitting help of a tiny winged insect, |
1:02.2 | the citrus cillid, which spreads the bacterium as it feeds. |
1:06.2 | But now researchers at the USDA and the University of Florida have come up with a pesticide-free way to battle the insect, |
1:12.6 | by disrupting its ability to find a mate. |
1:15.6 | When male sillids are looking for love, they beat their wings, sending vibrations along a tree's branches. |
1:21.6 | Nearby females pick up that signal and send back one of their own, |
1:25.6 | which tells males to come hither. |
1:28.3 | The researchers eavesdropped on that duet with a microphone, rigged to an electronic microcontroller, |
1:33.3 | and when the controller identified a male's call, it sent out a decoy female response, |
1:38.3 | more quickly than real females could respond. |
1:41.3 | And that imposter's call actually lured males to the device, where instead |
1:45.9 | of a mate, they found flypaper. The researchers presented the results at a meeting of the |
1:50.8 | Acoustical Society of America in Jacksonville, Florida. The technique isn't ready for the limelight |
