  • Split image of aerial view of city blocks next and a smiling person. Caption: It's the legacy of an evolutionary balancing act

    Human ancestors in Africa likely had dark skin, which is produced by an abundance of the pigment eumelanin in skin cells. In the high ultraviolet (UV) environment of sub-Saharan Africa, darker skin offers protection from the damaging effects of UV radiation. Dr. Jablonski explains that the variation in skin color that evolved since human ancestors migrated out of Africa can be explained by the tradeoff between protection from UV and the need for some UV absorption for the production of vitamin D.

  • Diagram of the upper body of a human exposing the skeleton, circulatory system, and lungs. Caption: The breastbone protects the heart and lungs.

    Students learn and explore the major features of the skin, skeletal, and muscular systems. Special attention is given to the care and maintenance of skin, skeletal, and muscular systems. Concepts and terminology include: integumentary system, layers of skin, sweat glands, bone, osteocytes, periosteum, marrow, cartilage, ossification, types of joints, ligaments, types of muscle tissue, and voluntary and involuntary muscle.

  • Closeup of the outside of a human brain. Caption: It's here that we take a flow of nerve impulses

    Presents sensory receptors that depend on contact with the immediate world: taste buds, touch sensors, and olfactory cells. These receptors lie in the skin, the largest organ of the body, which also senses heat, pain, and pressure. Re-creates the complex world of the skin through realistic models and photographs.

  • Squid with a white body speckled in reddish brown. The color of the head matches the color of the speckles on the body. Caption: His brain has total control over what his skin is doing.

    When the nerve cells of squid suffer an injury, something unexpected happens with the tiny pouches of colored pigment, called chromatophores. A MIT scientist discusses this phenomenon, and how it can be used and modeled on the computer with some surprisingly simple rules. Part of the "Science Out Loud" series.

  • A biological skin and a bioinspired e skin. The e skin consists of synthetic layers instead of biological layers. Caption: work together to give our hands their extraordinary sensitivity.

    New research reveals that loss of sleep leads to increased anger. Researchers are now studying the link between loss of sleep and aggressive behavior. Other segments include bacteria that consume greenhouse gases, a handy robot glove, and drones mapping marine megafauna. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.

  • Young person sitting on an examination table with leg extended while someone looks at it. Spanish captions.

    When Brandon was 10 he was diagnosed with psoriasis. At first, he was very ashamed due to the visible patches on his skin. However, five years after his diagnosis, with adequate treatment, he lives with the disease and has a normal life.

  • Grape fruit. Two grape pulps with their skin peeled are zoomed in. Caption: because they are fermented with the grape skins.

    Wine making has become a sophisticated scientific process, from the grafting of two different types of vines, to making growing possible anywhere in the world, to the technology used to create a red or a white. Every step is precisely thought out. Part of the "Science to Go With Dr. Joe Schwarcz" series.

  • Young person in a dentist's chair. Caption: Tooth decay, skin acne, and body odor

    Where do bacteria live, and how long have they been here? How can you tell them apart? What do they do to people and the environment? Answers these and other questions in this overview. Examines the fundamental structure of the bacteria cell, types of bacteria, and their importance to humans and the environment.

  • Person wearing a jumpsuit with a NASA logo holds a flame to an inflated balloon. Caption: that it takes the heat away from the skin of the balloon

    This demonstration uses a water balloon to show how Earth's oceans are absorbing most of the heat in the atmosphere. The trapped heat in the ocean is warming the planet. Part of the “DIY Space Classroom Activities” series.

  • A specimen of a wild cat. Caption: It's a sculpted animal that the skin is then glued to.

    Host Trace Dominguez learns about taxidermy and how museums ensure specimens in collections are preserved. He interviews a taxidermist, and she discusses some of the techniques and procedures used to ensure that the specimen will not decay and remain as realistic as possible.

  • Computer screen with a closeup image of an area of a person's body. Corresponding area is outlined on a diagram of the body. Caption: used to examine suspect skin conditions.

    Today's optoelectronic engineers are developing extremely thin glass that is both durable and scratch-resistant. Telecommunications systems require speed and accuracy, and glass is proving to be important in developing semiconductors, optical fibers, and multiplexing. Precisely engineered glass is also used in terrestrial and extra-terrestrial telescopes.

  • Closeup of a mosquito with proboscis piercing human skin. Caption: When a mosquito infects a person with dengue virus,

    Viruses are tiny agents that can infect a variety of living organisms, including bacteria, plants, and animals. The Dengue virus is a mosquito-borne viral disease occurring in tropical and subtropical areas. Scientists at the University of California, Berkley have identified a key culprit responsible for the severe symptoms related to Dengue fever.
