The Lab at azcentral

azcentral.com

In each new season, the bioscience team at azcentral.com examines a new element of scientific research to show you what it means for how we live today.  Season one is all about “weird science.” You’ll find fish that swim in the desert, tiny insects in cage matches and robots that talk to plants. It all sounds pretty strange.  But behind some of their weirdest scientific experiments, researchers are learning some things that are life-and-death serious. The changing climate, the future of degenerative neurological diseases, the future of human life itself ... some of it might someday depend on these weird cases.

    How can pollen solve a crime?

    Maybe when you think of pollen, you think of bees, or a commercial for allergy medicine.  But what about cracking cold cases? It might sound like a Sherlock Holmes story, but this is real life: unlike some other forms of evidence, pollen sticks around on hair, clothes and objects for a long time. And the unique shapes of pollen grains under a microscope can reveal geographic clues that help detectives track down everything from missing persons to counterfeit goods. In this episode, you’ll meet the only three forensic palynologists (AKA pollen-science sleuths) in the country. You’ll also meet an ASU researcher working on mathematical models that could make it easier for investigators to pinpoint where pollen samples are coming from. Along the way, you’ll learn the surprising ways that environmental change and crime-solving technology intersect – and how two species of cedar trees helped catch a killer. So grab your magnifying glass, put on your trench coat, and follow us into The Lab for the last episode of Season 1. Content note: This episode is about how scientists use pollen to help solve crimes. We won’t go into graphic detail, but we will discuss some of those crimes, including a case involving the death of a child. If you ever find yourself in possession of a microscope and an unknown type of pollen, this guide could help you figure it out. (It also has lots of cool images illustrating the shapes of different species’ pollen grains.) Learn more about forensic palynology and Daoqin Tong’s mathematical modeling research in this piece from ASU. Read about how U.S. Customs and Border Protection is using pollen as a forensic tool in this CBP magazine from 2016.

    Why are they raising fish in the desert?

    On family trips to San Diego, George Brooks used to collect hermit crabs and sea stars and bring them back to Phoenix. What followed was a lifetime of raising fish in the desert. He, and others in Arizona, aren’t just doing it for the love of all things scaly, shiny and gilled.  Researchers and community leaders like Brooks see big potential in these small creatures, to solve local problems that have global implications.  In this episode, you’ll hear about prawns in kiddie pools and zebrafish revealing the secrets of the human genome. You’ll also hear about the promise of aquaculture (that’s basically agriculture + water) to bring food systems closer to home while preserving the ocean far from our landlocked state. How? Come – or swim – along, and let’s find out. Read more about Phoenix aquaculture pioneer George Brooks in this 2020 story: https://www.azcentral.com/story/news/local/arizona-environment/2020/08/10/arizona-aquaponics-pioneer-george-brooks-preaches-edible-landscapes/5532656002/  Watch George Brooks’s TED Talk: https://m.youtube.com/watch?v=Yb495LDRNs4 Learn more about Benjamin Renquist’s genetics-based aquaculture technology company, GenetiRate: https://www.genetirate.fish  Take a deeper dive into the state of global fisheries and aquaculture with this interactive summary from the Food and Agriculture Organization of the United Nations: https://www.fao.org/state-of-fisheries-aquaculture/en/.

    What are the plants saying?

    When scientists are talking to plants, they’re trying to ask them questions. What do you need to grow more effectively? To produce crops more efficiently? And sometimes, they’re asking something else: Now that you’re in a drought, and you’re not getting any water, how are you going to react? Yes, they’re asking questions, and they’re getting answers. But the answers are about something bigger than next year’s crop.  In our second episode about talking to plants, you’ll go to a desert farm field and a humid rainforest. You might not believe this, but both of them are in Arizona.  And you’ll hear from one person who isn’t talking to plants at all. She’s talking about the climate they’re living in – the one we’re all living in.  Join us in the Lab, to hear what the plants – and the people – have to say. Our exploration of plants, and the people who talk to them, really started when we looked at the people taking genes from succulents and using them to help other kinds of crops save water.  We said the story of the original research at Biosphere 2 would probably need to be its own podcast. Our colleagues at The Arizona Republic give you a little taste of why, here, and here.  Laura Meredith, who gave us the tour of Biosphere 2 along with her colleague Joost van Haren, worked on the drought experiment there. That research was published in the journal Science.  Antonieta Cadiz, who told us about her family’s encounter with climate change, is an advocate for the group Climate Power.
