One of the fifteen parts of the "Farm to Market" series. Consumed by both people and animals, corn and rice are two of the most important food crops in the world. Shows how they are grown and harvested. Talks about different types of corn, such as popcorn. Planting rice in flooded fields from the perspective of a person in a rice-seeding plane is overviewed. Also shows how these crops have alternative and environmentally friendly uses, such as rice straw and fuel.

The evolution of the uses of corn coincides with some significant historical events. Throughout history, it has been a staple in the human diet, but in the 1950’s, it became the main ingredient in the meat industry. Farmers used corn to shrink the growth periods of cattle to meet the demand of the consumer. Corn syrup was born from the Cuban Embargo. Today, genetically engineered corn is seen in nonfood products.
Ten thousand years ago, corn didn’t exist anywhere in the world, and until recently scientists argued vehemently about its origins. Today the crop is consumed voraciously by humans, by livestock, and as a major part of processed foods. So where did it come from? Evolutionary biologist Neil Losin tells the story of the genetic changes involved in the transformation of a wild grass called teosinte into corn. Evidence from genetics supports archeological findings pinpointing corn’s origins to a very particular time and place in Mexico.
Corn is king. It can be found in other foods, in the ink for pens, and in gas for cars. Indeed, it's one of the most versatile substances on the planet. Today, it is a very different product than the one that once grew wild across North America. In this episode, Dr. Joe Schwarcz traces the evolution of corn. Part of the "Science to Go With Dr. Joe Schwarcz" series.
Cornell geophysicist Katie Keranen traveled to Oklahoma to study the increased occurrences of earthquakes. During her research, she discovered the increase in seismic activity is linked to the disposal of wastewater from fracking.
Sea star wasting syndrome is the largest marine disease event ever seen. Microbiologist Ian Hewson shares what inspires him to study oceanic ecosystems, and how scientists from Cornell University are solving this ecological mystery.
The business world has forced agricultural researchers and producers to improve production systems by either increasing the quality of the product, size, or growth process. All these issues are part of the concept of Biotechnology.
Nourish is an educational initiative designed to open a meaningful conversation about food and sustainability, particularly in schools and communities. In this clip, author Michael Pollan defines monocrops and how these crops have changed agriculture. Part of the Nourish Short Films Series.
In this chapter, the scientists will try to find the best corn to make the biggest popcorn. They will also have a lot of fun with optical illusions. And finally they will show how eyeglasses gather light by using lasers. Part of the House of Science Series.

In this episode, host Dianna Cowern races against the clock to complete 20 physics experiments in five minutes. Feel free to try them at home but note that some require adult supervision. Part of the "Physics Girl" series.

Argentinean agriculture has one of the world’s highest productivity rates and is known for its soybean, corn and sunflower crops. However, the industry is also a significant contributor of greenhouse gas emissions. These climatic changes could in turn affect the productivity of the agricultural sector as well as impact economic aspects of the farmers’ lives. Chapter 3 of Air: Climate Change Series.
Breakfast cereal was the birth of the health food movement. Before that, breakfast was usually a fatty and vein-clogging combination of bacon, fried eggs, flapjacks, and a mound of butter. The advent of corn flakes, oatmeal, and other quick-to-prepare breakfast foods changed the way people start their day. Part of the "Science to Go With Dr. Joe Schwarcz" series.

A chart of exponential growth shows that some things change faster over time. Back in 1798, Thomas Malthus noticed that not everything grows this way. This caused people to worry, and they were sure it would lead to massive death, starvation, and famine. However, the Green Revolution kept this from happening, and scientists are currently working to produce enough food for the current exploding population. Part of the “It’s Okay to Be Smart” series.
With today's high fuel costs, it is time to start looking beyond petroleum and into renewable resources to power vehicles. Ethanol is a clean-burning fuel derived from plants, primarily corn. It is combined with gasoline to produce a cleaner fuel that doesn't emit as many greenhouse gases as pure gasoline. Pure ethanol has not yet been approved to fuel vehicles, but it is the fuel of choice for racecars. By mixing gasoline with ethanol, fuel supply can be extended. Explores the production of ethanol and highlights the importance it holds in the "green power" movement.
At first, the back room of plant physiologist Edgar Spalding's lab at the University of Wisconsin-Madison might be mistaken for an alien space ship set straight out of a Hollywood movie. It's a room bathed in low-red light with camera lenses pointing at strange looking entities encased in Petri dishes. A closer inspection reveals the Petri dishes contain nothing alien at all, but rather very down-to-earth corn seedlings. They're grown in red light for optimal growth. They're just one of the plants featured in thousands of time-lapse movies Spalding has created over the past five years. The goal is to figure out how to grow crops optimally.
Explains the names and functions of different parts of the human eye. Shows how the eyes and brain work together to see color and light. Tells how tears help keep eyes clean and healthy. Describes ways that a person's age affects their sight.
Welcome to the North Carolina State University (NCSU) Phytotron, a singular facility for growing plants under various combinations of strictly controlled environmental conditions. Scientists are able to conduct all types of plant research here, from studies of disease-resistant crops to drought-proof grasses to new biofuels. The NCSU Phytotron was built in the 1960s with support from the National Science Foundation (NSF), and was used a decade later to help prevent a collapse in the U.S. corn crop from fungal disease. Now, after more than a generation of such research breakthroughs, the Phytotron has received additional support from NSF for a 21st century makeover. The renovations include a new Biosafety Level 3 (BSL-3) lab with a greenhouse that houses high security research, such as experiments with viral and bacterial pathogens. Part of the National Science Foundation Series “Science Nation.”
