Part of the "Branches on the Tree of Life" series. Phylum Arthropoda is the most luxuriant branch on the tree of life. Covers phylum characteristics and three major arthropod classes: Crustaceans (copepods, waterfleas, branchiopods, decapods, and barnacles), Chelicerates (scorpions, pseudoscorpions, spiders, ticks, and mites), and Uniramians (centipedes, millipedes, and insects). Focuses on adaptations, life cycles, and evolutionary relationships in each section.

With recent advances in genetic and reproductive technology, couples can now rely on science to avoid giving birth to children with various genetic conditions. Explores the medical and ethical dilemmas that two couples face as they plan the birth of a child who may inherit their own genetic condition (dwarfism in one case, cystic fibrosis in the other). Bioethicists question the use of technology to ensure parents give birth only to a healthy child. NOTE: Includes footage of a baby being born via Caesarian section.
The Standard Deviants start off with the concept of heat transfer. Students learn how much energy it takes to raise the temperature of a substance. This episode also discusses how matter changes state. Part of the "Standard Deviants School: Physics" series.
Part of the "Inside the Living Cell" series. Illustrates the mechanisms of photosynthesis and cellular respiration. Introduces adenosine triphosphate, or ATP, the universal energy carrier molecules that supply energy-hungry reactions. Also outlines the structure and function of chloroplasts and mitochondria, energy transforming organelles. Overviews ATP and chemical energy, mitochondria, aerobic respiration, chloroplasts, and the reactions of photosynthesis.
Algae play a vital role in the marine ecosystem. They provide food for all sorts of species, but in rare instances, they can also do harm. Harmful algal blooms occur when colonies of certain types of algae grow out of control and produce toxins that enter the food chain through fish and shellfish. Eventually, the toxins can kill larger marine animals like sea lions, manatees, turtles, and dolphins. It also makes shellfish unsafe for human consumption.
Psychiatrist and author Dr. Norman Doidge travels across North America to meet some of the pioneering researchers who made revolutionary discoveries about the plasticity of the human brain. He also visits with people, once thought to have had incurable brain injuries, who are now living normal lives. Known in scientific circles as "neuroplasticity," this radical new approach to the brain provides an incredible way to bring the human brain back to life.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the crew explores the extreme environment of a shallow salty sea. Their mission is to discover the chemical conditions of a living microbial mat. Part 13 of Microscopic Monsters Series.
This video introduces science lab safety guidelines. Some topics covered include discussions on proper lab attire, importance of proper disposal of materials, and precautions when heating substances. Part of "The Amoeba Sisters" series.
In this episode, host Emily Graslie learns the proper techniques for pinning an insect. Gracen Brilmyer, a research assistant at the museum, provides Graslie with step-by-step instructions from collecting the best specimen to showcasing anatomical structures. Part of "The Brain Scoop" series.
The connections between neurons in the brain are involved in everything humans do, and no one’s pattern is the same. Imagine the medical breakthroughs if doctors understood more about the brain’s circuitry. With support from the National Science Foundation, neuroscientist and psychiatrist Karl Deisseroth and his multidisciplinary team at Stanford University have developed a new imaging technology that essentially makes the brain transparent. They can then generate detailed 3-D images that highlight specific neuronal networks. Deisseroth has named this process “CLARITY.” Part of the National Science Foundation Series “Science Nation.”
What happens in your brain when you get lost or forget something? Johns Hopkins University Neuroscientist Amy Shelton believes she can find the answer. With funding from the National Science Foundation, she’s testing human spatial recognition. Study subjects learn and recall their way around a virtual maze while an MRI scans their brains. By analyzing MRI images of blood flow in the human, Shelton can get a picture of how the brain learns and recalls the spatial world outside the body. By understanding those processes, she believes she can develop techniques that will help improve human memory.
Researchers around the world can compare notes on one of the most powerful tools available for imaging human brain function, the fMRI, thanks to support from the National Science Foundation (NSF). The project, called OpenfMRI, allows scientists to share their data easily and securely in a standardized format. The advantages are clear to Stanford neuroscientist Vinod Menon, who researches brain development and is using OpenfMRI to validate his research. Menon says as more studies are added to OpenfMRI, it becomes a powerful tool for diagnosing and treating neurological disorders. Part of the National Science Foundation Series “Science Nation.”
Neuroanatomist Jacopo Annese is looking for 1,000 brains. The Director of the Brain Observatory at the University of California, San Diego is on a quest to collect, dissect, and digitize images of the human brain for the Digital Brain Library, which was launched with support from the National Science Foundation. Annese and his team look for connections, mapping brain structure and connecting it to human behavior. He believes that with a large enough catalog of brains preserved as virtual models, scientists can explore the organ in ways unheard of, revealing new insights into what makes the brain tick.
Host Emily Graslie travels to the Denver Museum of Nature & Science, and she explores the health sciences collection. Dr. Nicole Garneau is the curator for the exhibit, and Graslie becomes the newest addition to the DNA collection. Part of "The Brain Scoop" series. Please note: This title shows donated human anatomy to the museum collection.

The heart is the most symbolic organ of the human body. Across history, it has been seen as the source of emotions and the center of human existence. However, by the seventeenth century, scientific understanding overturned historical ideas, and the heart was recognized merely as a mechanical pump. More recently, Professor David Paterson from the University of Oxford has been doing extensive research that challenges this view. He has discovered that the heart has millions of specialized neurons just like those that are in the brain. Neurons are the cells that give humans the ability to think. So what does their presence in the heart mean?
As shown on the History Channel. Gold dates from the time of the supernova explosion that gave birth to the building blocks of our solar system. When it was created, the Earth included a tiny percentage of gold atoms, and over the aeons geologic processes have concentrated it into various nooks and crannies around the globe. The best of it is in the ancient Precambrian rocks in South Africa, where the deepest mines in the world extract it. In other regions of the world, gold can be gathered from younger sedimentary rocks that have been eroded off older Precambrian rocks. The American gold rush was this type of deposit. Now in Nevada, sedimentary rocks are leached on a truly vast scale to extract the gold.
The Center for Remote Sensing of Ice Sheets (CReSIS) is a Science and Technology Center established by the National Science Foundation (NSF) with the mission of developing new technologies and computer models to measure and predict the response of sea level change. CReSIS provides students and faculty with opportunities to pursue exciting research in a variety of disciplines; to collaborate with world-class scientists and engineers in the US and abroad; and to make meaningful contributions to the ongoing, urgent work of addressing the impact of climate change.

As shown on the History Channel. In the remote wastes of Siberia buried under snow are the remains of one of the greatest catastrophes that the Earth has endured. 250 million years ago, huge volumes of lava spewed out onto the surface--so much that it would have buried the whole of Texas under one mile of lava. At first the temperature dipped but then the greenhouse gases that escaped from the depressurized lava caused a massive global warming. It wreaked havoc, and 95% of the species on Earth became extinct. Yet life hung on and in time this disaster paved the way for the next phase of life on earth--the age of the dinosaurs.
