Description
A Kid for the Wild is a playlist of 11 ecology music videos created by Judy Lehmberg, a former college biology, zoology and botany teacher, now filmmaker. The majority of songs are by the late Walkin' Jim Stoltz, a singer songwriter, poet, photographer, painter and long distance hiker from Big Sky and Helena, Montana. Jim hiked over 28,000 miles through the wilderness of North America – a true mountain man who experienced the wonder and wisdom of...

See how the cognitive changes of aging relate to the biological changes discussed in the previous lectures. It turns out that regions of the brain associated with processing speed, executive function, and episodic memory are more susceptible to aging, which may explain why these cognitive functions are particularly susceptible to decline.

Take a tour through the 20 amino acids that link together in different combinations and sequences to build proteins. Besides water, proteins are the most abundant molecules in all known forms of life. Also the most diverse class of biological molecules, proteins make up everything from enzymes and hormones to antibodies and muscle cells.

Algae have sustained life on this planet since they were first modified by the atmosphere with photosynthetic by-products over two and a half billion years ago. From the microscopic to giant seaweeds, over 30,000 different forms exist today. In this program researchers discover how algae can transform, from life supporting to life threatening. Learn how we've depended on algae in the past and see the new ways we are putting them to use in cancer research,...

RNA is more than simply a copy of the DNA blueprint. Focus on the synthesis of RNA, covering how it differs from DNA replication. Also learn how human cells shuffle their genetic code to make about 100,000 different proteins using fewer than 30,000 coding sequences. Finally, see how knowledge of transcription occurring after death helps forensic scientists establish the time of death accurately.

Explore the controls that determine which genes are expressed at a given time, where in the body, and to what extent. Controls that act over and above the information in DNA are called epigenetic, and they can be passed on to offspring for a generation or two. Consider the case of honeybees, where a special food affects which genes are expressed, turning an ordinary larva into a queen bee.

Advance into the last third of the series, where you cover molecular biology, which deals with the biochemistry of reproduction. Zero in on DNA and how its double-helix structure relates to its function. Then look at the single-stranded RNA molecule, which is a central link in the process, "DNA makes RNA makes protein."_x009d_ Also consider how viruses flourish with very little DNA or RNA.

A metabolic pathway is a series of biochemical reactions, where the product of one serves as the substrate for the next. Biochemists compare these pathways to road maps that show the network of reactions leading from one chemical to the next. Follow the metabolic pathway called glycolysis that breaks up glucose and other sugars. Then trace the route for fatty acid oxidation.

Roughly 10,000 human diseases may be caused by mutations in single genes. Review the nature of genetic disorders, such as cystic fibrosis, hemophilia, and Alzheimer's. Also examine diseases that emerge from mutations in mitochondrial DNA. Finally, assess the challenges of using gene therapy and other technologies to treat genetic diseases.

Nitrogen is a key component of amino acids, DNA, and RNA, yet animal and plant cells are unable to extract free nitrogen from air. See how bacteria come to the rescue. Then follow the flow of nitrogen from bacteria to plants to us. Also look at strategies for reducing our reliance on environmentally unsound nitrogen fertilizers by exploiting the secret of 16-feet-tall corn plants found in Mexico.

Probe the biochemistry of sugars that provide us with instant energy, feed our brains, direct proteins to their destinations, and communicate the identity of our cells. On the other hand, when present in large quantities, they can lead to Type 2 diabetes, and the wrong sugar markers on transfused blood cells can even kill us.

Study how plants use sunlight and reduction reactions to build carbohydrates from carbon dioxide and water. This synthesis of food from air and water occurs in a series of reactions called the Calvin cycle. While humans exploit plants for food and fiber, we also utilize a multitude of other plant molecules called secondary metabolites. These include flavors, dyes, caffeine, and even catnip.

Cells go to great lengths to prevent mutations. Luckily, these measures are not quite perfect, since nature relies on mutations to drive evolution. Study the methods that cells use to minimize alterations to their DNA. Find that DNA repair can interfere with cancer treatment, when the malignant cells survive medical therapy by repairing their DNA faster than the treatment can halt the repair.
