The Science of Microplastics. What exactly are microplastics and why should we care? Are microplastics making us sick? Can science save us from microplastic pollution?

In Episode 14 Emmaline and Kincaid break down the science of microplastics. 1. What is the extent of the current plastic waste problem?  2. Does plastic pollution increase your risk of cardio vascular disease or dementia?  3. What technology is being developed to tackle plastic pollution?  Find out the answers and more in this episode! Summary: In this episode of the Science Tapes, hosts Kincaid and Emmaline explore the dangers of plastic pollution. They dive into how plastic waste is one of the top threats to the planet, how plastic is potentially causing disease, and what technologies are being designed to clean up and prevent plastic waste. They interview Dr. Joseph Pennycook to explore how genetically modified organisms (GMOs) can be used to our benefit in the battle against plastic waste! They discuss the ecological considerations of introducing GMOs into the environment. The episode concludes with a reflection on the future of plastic and the importance of sustainability in addressing environmental challenges. Takeaways: Plastic waste pollution is a serious and concerning problem. Innovative solutions are emerging to tackle plastic waste. Microbes may offer a way to solve environmental problems. Health impacts of microplastics are still being studied. Technology is playing a crucial role in addressing plastic waste. Ecological balance must be considered with GMOs. The environment is constantly changing and evolving. Public awareness and action are essential in combating plastic pollution. Sustainability is key to future environmental health. References: 1.

The Science of Rewilding. What is rewilding? What are the most successful rewilding projects?

In Episode 13, Emmaline and Kincaid are joined by PhD student Mia Arundel to explore the science and practice of rewilding.   1.    What exactly is rewilding? 2.    What are some of the most successful rewilding projects? 3.    Are childhood stories negatively affecting our opinions on rewilding? 4.    What can we all do to help with the rewilding efforts? Find out the answers and more in this episode!   Summary: In this episode, they discuss the concept of rewilding, its significance in restoring biodiversity and the challenges associated with reintroducing species in the UK. Mia shares the importance of creating ecosystems that can thrive with minimal human intervention and the complexities involvedin rewilding efforts. The discussion highlights the importance of predator-prey dynamics and the necessity of public acceptance for successful conservation efforts. They share successful rewilding stories and tips on how everyone cancontribute to rewilding in their everyday lives.   Takeaways: 1.    Rewilding aims to restore natural ecosystems and biodiversity. 2.    The UK is one of the most nature-depleted countries in the world. 3.    The reintroduction of apex predators can reshape ecosystems 4.    Successful rewilding requires social acceptance and ecological feasibility 5.    Planting native wildflowers can enhance local biodiversity.   Want to learn more?

The Science of the Night Sky. What causes the northern lights? How can you photograph the cosmos from light-polluted cities?

In Episode 12, Emmaline and Kincaid break down the science of the night sky.  1. What’s behind nature’s most stunning light show: the Northern Lights? 2. Why have we seen such strong Auroras in the last year? 3. How do you take images of the night sky from light polluted cities? Find out the answers and more in this episode! Summary: In this episode we explore the mysteries of the night sky. We discuss the science behind the aurora borealis, how light pollution is on the rise, and how to image the night sky from light polluted cities. We are joined by expert deep sky astrophotographer Lee Pullen, who captures images of the cosmos from his back garden in Bristol. Check out Lee's incredible images here: https://urbanastrophotography.com/ Takeaways: 1. Auroras are formed as charged particles from the Sun collide with our atmosphere. 2. Auroras form on other planets, not just Earth. 3. The Northern Lights are best seen through photos due to the increased exposure time. 4. Light pollution is getting worse each year. 5. Capturing the night sky from light polluted cities is possible. 6. Astronomical darkness cannot be achieved in the summer, making imaging a little more challenging.  Want to learn more?
