Trees Can Help Beat City Heat

Politics Race Health Environment Climate Change Human Impacts Class Plants Conservation Air Pollution Natural Resources

Low-income urban neighborhoods are often hotter than wealthier neighborhoods in the same city. This is problematic, especially during heat waves, when residents’ health and even their lives could be at risk. One of the reasons poorer areas get hotter is because they tend to have fewer trees. Listen to learn how trees keep communities cool and why they are more prevalent in some neighborhoods than others.

Edible Art Garden

Environment Engineering Arts Nutrition Plants

When a vacant lot in Sacramento was up for sale, one neighbor had an idea for what it could become. She envisioned an urban farm, so she bought the lot and invited a local nonprofit group to help turn it into an “edible art garden” after gathering input from other community members. Listen to learn what this once bare lot looks like today and how it benefits the neighborhood surrounding it.

Changing Consumers' Minds About "Ugly" Produce

Environment Climate Change KERA Human Impacts Agriculture Nutrition Plants Business Industry Conservation

Would you eat a scarred, lumpy carrot or an apple that is oddly shaped? Grocery stores do not typically sell these types of “ugly” produce, but some new companies aim to reduce food waste by selling fruits and vegetables that are rejected by stores. Listen to learn about the benefits of these efforts and find out what else you can do to reduce food waste.

Modifying Plant DNA with a Nano-Needle

Technology Engineering Genetics Plants Biology

Would you like to eat apples that never turn brown? Scientists hoping to genetically modify plants for crop development think they may have found a solution to a major problem they have been facing. The cell walls of plants make it difficult to insert genetic material into plant cells to change how those plant cells work. The solution–carbon nanotubes–was discovered by accident. Listen to learn about the discovery and implementation of this nanotechnology solution and how it could change the way scientists breed new crop varieties.

Hacking Photosynthesis

Life Science Genetics Nutrition DNA Biotechnology Plants Biology

Photosynthesis is the process that is foundationational for all life, in which plants use sunlight to change water and carbon dioxide into food and oxygen. Scientists have now genetically modified plants to perform that process more efficiently, thereby increasing agricultural productivity. Listen to this story to learn how researchers “hacked photosynthesis” and why it matters.

Learning to Garden and Cook in School

Life Science Health Nutrition Plants

Many schools now have gardens where students grow and harvest food that they cook themselves in class. The “Let's Move Initiative,” a program created by former First Lady Michelle Obama in 2010, has generated awareness about school gardens and teaching cooking skills that enable students to learn about healthy lifestyle habits in an effort to fight the national obesity epidemic. Listen to learn more about how a gardening and cooking project at a school in Maine is a rewarding way to learn about nutrition and healthy lifestyle skills through hands-on class activities.

Stores Lack Biodiversity in Apples

Life Science Nutrition Plants

The apples we are used to seeing in the supermarket are the same basic size and shape and they have familiar flavor profiles. But there are more apple varieties than you might imagine. There's a whole world of biodiversity in apples, but these apples don’t make it to the supermarket. Listen to learn more about America’s history with apples and the apple Renaissance taking place today!

Artificial Photosynthesis Produces Fuel

Life Science Engineering Biotechnology Plants

While humans need food and water to survive, plants are able to get their energy from the sun through a process known as photosynthesis. Engineers are now trying to replicate this process of converting sunshine to power through artificial photosynthesis. They are trying to create an artificial leaf. Listen to learn how these problem solvers are approaching the challenge step by step.

Heirloom Seeds Bring Back Diversity

Life Science Plants Ecology

Heirloom seeds are more than 50 years old and are not genetically modified. Jere Gettle, author of "The Heirloom Life Gardener," is particularly fascinated by heirloom seeds and he noticed they were being dropped by seed catalogs in the 1980s. The plants they produce are typically different from what we see in the grocery store. Listen to learn more about Gettle’s fight to bring heirloom plants back to our dinner tables.

Fungi Sustain Ecosystems

Life Science Ecosystems Nutrition Plants

Fungi play a crucial role in decomposition. As they follow this process, fungi release nutrients that the trees around it absorb. Eventually, the fungi attach itself to the roots of the nature around them and begin the cycle of giving and getting to keep the environment in balance. Listen to learn how fungi first colonized land and what would happen if fungi were not able to spread.
