0:00.0 | Hi, I'm Wendy Zuckerman and you're listening to Science Verses. |
0:05.1 | Today on the show, the unprecedented and sometimes rather strange things that have been happening to science in the US recently. |
0:20.8 | Milkshakes bring all the boys to the yard, so they say. |
0:25.1 | But recently they've also been courting some controversy. |
0:28.5 | Rose Rimlet, senior producer at Science Verses, tell us about the milkshakes. |
0:33.3 | Okay, so this all started a couple months ago. |

1:11.0 | So what the scientists at the NIH wanted to see was whether drinking a milkshake could cause |
1:17.1 | someone's brain to send out a big whoosh of dopamine in the same way that you might see with |
1:22.9 | addictive drugs, right? Like that happens with cocaine, for example. So was the milkshake? |
