Hear and Now: Chemtrails, Canines and, Well, Venus HowStuffWorks

Greetings and salutations! Here's a preview of the three stories you'll hear about in this week's episode of the HowStuffWorks Now podcast.

If you're one of the 54.4 million U.S. households with a dog in the mix, you'll be happy to hear about this study that Robert Lamb tracked down from Emory University. The study found that your dog might love praise from you at least as much or more than he or she loves food. Admit it: You've always kind of wondered, haven't you?

So how did the researchers figure that out? Well, it involved 13 canines, a lot of patience, a functional MRI machine and a Y-shaped maze, among other things. Listen to the embedded podcast or watch the video at the end for more details on the methodology and the overall experiment.

Jonathan Strickland alerted us to a new study that solidly debunks the fringe theory of chemtrails. Not sure what those are? They're those cloud-like trails that jets flying at high altitudes leave behind them and that some people think are made of chemicals.

Researchers asked 77 different geochemists and atmospheric scientists what they made of data that conspiracy theorists frequently cite as evidence supporting the chemtrail hypothesis. Exactly how many of them said that the data weren't suitable evidence? Jonathan has the finer details in the podcast and video.

Host Lauren Vogelbaum steered us toward another planet in our solar system that may have been habitable at one point: Venus! (Sorry, Mars, we know you're accustomed to hogging all the headlines in that regard.) Of course, if you were to drop onto Venus right now, you might feel like you were being simultaneously cooked to a crisp and crushed to death by the crazy dense atmosphere, but things weren't always so dire. For almost half of its 4.5 billion years, Venus may have been more welcoming to life. At least, that's the idea that NASA climate-modelling science has introduced. You can find the study here.

That's our trio for the HowStuffWorks Now podcast this week, which we've embedded for your listening pleasure in this article. If you like what you hear, please subscribe
