Sidhu Moose Wala explodes onto the Canadian music scene. His sound is a fusion of two worlds - hip-hop with the poetic language of rural Punjab, where he is from. After years of struggle he’s making it. But with the spotlight comes a dark side. As his fame grows, so do the threats. "We will kill you." Presented by broadcaster and DJ Bobby Friction and investigative journalist Ishleen Kaur. Season 8 of World of Secrets, The Killing Call, is a BBC Eye investigation for the BBC World Service.

The gang discusses two papers that look at the evolution of photosynthesis in different groups. The first paper looks at what might be the first fossil evidence of thylakoids, and the second paper finds evidence for photosynthesizing symbiotes in Devonian fossil corals. Meanwhile, Amanda is making a lasagna, James has a lot of opinions about lasagna (~10 minutes until we actually get to the paper), and Curt is all about those sponges.

Up-Goer Five (Curt Edition):

The friends talk about two papers that look at how some types of living things can make food from the sun. The first paper looks at these very very old things that are very very very small. Inside these things they find very very very small parts of things that are used today by some living things to help make food from the sun. This might be the oldest one of these things that we have ever found, and it makes it so that we can see how things might have gotten better at making food from the sun over time.

The second paper looks at old animals that live in the big blue wet thing that all live close together and make big hard parts that make walls in the water. These old animals are like the ones we see today but they are a group that is not around anymore. Groups today have friends that help make food from the sun for them. This paper looks to see if the old animals had those friends (or friends like them) too. They find that animals today keep some bits of things they do not usually want so that their friends can eat them. This can be seen in the hard parts they make. When they looked at the hard parts of the old group of animals, they saw that they were doing this too. This means that these animals were keeping food for friends just like that animals we see today.
