Host Emily Graslie meets with Dr. Ryan Felice to discuss the 3-D surface scanner, which he uses to create digital representations of skeletal anatomy. He visits various museums and scans their collections hoping to help preserve research findings. Part of "The Brain Scoop" series.

Take a tour of the moon's surface. Images and topographic maps show craters, rocks, mountains, basins, and valleys found on the moon. These maps help improve scientific understanding of how Earth's moon and other rocky planets in the solar system evolved.
Tour three Martian landscapes and find out how erosion and water has affected the surface of Mars. Flyover images show the structure and composition of the landscape of Mars and focus on Candor Chasma, part of a canyon system of Mars.
Jupiter's moon Europa may have an ocean more than twice the size of Earth's oceans combined. Why do scientists think so? A spacecraft collected evidence that revealed Europa's surface is mostly made of water. It also showed lots of cracks and ridges, but not many craters, which may indicate a large hidden ocean.
On January 14, 2005, the European Space Agency's “Huygens” probe made its descent to the surface of Saturn's hazy moon, Titan. Carried to Saturn by NASA's “Cassini” spacecraft, “Huygens” made the most distant landing ever on another world and the only landing on a body in the outer solar system.
Gravity and erosion are major factors in changing the shape of the surface of Earth. The different types of erosion and the effect of gravity on objects is discussed in this video. Other topics covered include folding, faulting, deposition, creep, mass movement, landslide, surface runoff, alluvial fan, delta, stream erosion, beach erosion, ice erosion, wind erosion, dune, glaciers, and glacial deposits.
Shows how the brain coordinates functions to make simple but lifesaving decisions. Provides an overview of how the cortex assesses incoming information, sends outgoing messages to the muscles, and stores "maps" of the world and the body. Also outlines how circuits of nerve cells operate in the brain and how individual nerve cells function.
Organics are carbon-based molecules and key ingredients to life. Scientists want to know if organics can be found on Mars. However, finding organics is difficult because they easily break down when exposed to harsh things like extreme radiation and chemical oxidants. These broken down particles give the Martian surface its rusty color. Part of the “Mars in a Minute” series.
In the last few years, the Red Planet has yielded up many new clues that life may have once existed there...and may even exist there today. There is now proof that water once flowed on the surface, that Mars once had lakes, and that the frozen poles are mostly water. Mars has snow--an aurora--and lightning generated by dust storms. Most intriguing of all are the seasonal plumes of methane that just may point to bacteria living below the surface.
The species of Goby fish, Sicyopterus stimpsoni, also known as the inching climber, thrives in the waters off Hawaii. To reach the safe haven of its freshwater spawning area, this Goby must scale a waterfall, or at least the rock behind it, using suction cups on its body. With support from the National Science Foundation, scientists at St. Cloud and Clemson Universities study these extraordinary fish to better understand how they’ve adapted and evolved in order to achieve such vertical feats. Part of the National Science Foundation Series “Science Nation.”
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.
Tongue taste areas The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication, and is used in the act of swallowing. It is of importance in the digestive system and is the primary organ of taste in the gustatory system. The tongue's upper surface (dorsum) is covered in taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva, and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. A major function of the tongue is the enabling of speech in humans and vocalization in other animals. The human tongue is divided into two parts, an oral part at the front and a pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of fibrous tissue (the lingual septum) that results in a groove, the median sulcus on the tongue's surface. There are two groups of muscles of the tongue. The four intrinsic muscles alter the shape of the tongue and are not attached to bone. The four paired extrinsic muscles change the position of the tongue and are anchored to bone. Do you have good taste? In this video segment, Dr. Linda Bartoshuk explores the sense of taste in humans - why we have it, and what happens when we lose it. Learn why the sense of smell is also important to our experience of food. Footage from NOVA: "Mystery of the Senses: Taste".

Highlights the limited information scientists have about the many moons in our solar system. Presents theories of origin and composition. Mixes graphics with pictures taken from spacecrafts.
Saturn has twenty-one moons, and each one has its own physical composition and location. From the Kool Books series narrated by Hector Bonilla.
Host Alex Dainis discuses the science behind striking a match. She explains how the chemical components of matches and the striking surface work together to produce fire.
Patrick Sanan, who studied mathematics at UC San Diego, explains how he combined geometry and physics to create the virtual tiger in the Oscar award-winning motion picture "Life of Pi."
In this episode, host Dianna Cowern discusses the physics behind vortex rings. She uses some food coloring in a swimming pool to demonstrate the creation of vortices. Part of the "Physics Girl" series.
Cutter is a young Atlantic spotted dolphin. When he was found in a busy harbor in Key West, he was dehydrated and malnourished. A team rescues and rehabilitates him.
Introduces physics concepts as they relate to mechanics, optics, and electricity. Supports the learning of these concepts in tandem with the textbooks also offered by the publisher. Encourages hands-on activities.
Though manned space flight began in 1961, any kind of off-earth colonization remains a dream. Astronauts and scientists speculate about the possibilities, dangers, and problems to be overcome.
