What are the differences between fish and shellfish? The scientists will explain their differences. The scientists also explore the rate that nails grow. Is it the same for everyone? Part of the House of Science Series.
In this episode, scientists try to uncover what makes 25 percent of individual corals tolerant of warmer water. Can these "super corals" be strategically planted to help reefs withstand climate change? Part of the "Super Corals" series.
Host Alex Dainis discusses GFP (Green Fluorescent Protein), and its importance in scientific studies. GFP is a green fluorescent protein found in jellyfish. Scientists use GFP in biology to mark particular genes in various experiments, and it provides a direct look into the inner workings of cells.
Part of the "The Biology Classics" series. Paramecia are a group of unicellular ciliate protozoa. Shows how paramecia move, feed, digest, assimilate nutrients, achieve water balance, deploy defensive weapons, reproduce, and engage in the sexual exchange of genetic material. Utilizes state-of-the-art microscopy techniques to present a compelling new picture of the life of paramecia.
Amy Battocletti is a Navy veteran who was awarded an NSF Graduate Research Fellowship in 2014. She’s a doctoral candidate in biology at Georgetown University, conducting research on the impact of genetic variation within plant species in salt marsh ecosystems. Part of the Scientists and Engineers On Sofas Series.
Figure 2.27 (OpenStax, Biology 2e) caption: These functional groups are in many different biological molecules. R, also known as R-group, is an abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule.

Research in biology would be impossible without a common framework for grouping and distinguishing species. Carl Linnaeus was the first to propose a classification system of organisms. His system developed into the organizational structure used in the life sciences today. Viewers also learn how new scientific names are created and how the existing system has been further refined using DNA studies.
Describes how coral reefs form and their importance to the sea life they sustain. Gives characteristics of hard and soft coral and shows examples, pointing out that both grow extremely slowly. Locates major coral reefs on a map and restates reefs' contributions to humans. Names several different threats that could destroy these wonderful phenomena.
An introduction to human biology-the subject of the most fascinating human study: ourselves. Shows a wide range of human activities and how the body enables us to live in diverse climates and perform diverse activities. Extraordinary close-up filming over the body's exterior and in its interior causes surface differences to fade away and shows the immensely complex and interactive systems that constitute the living body. NOTE: Contains some nudity.
Part of the "The Biology Classics" series. Hydra is a genus of simple fresh-water animals possessing radial symmetry. Observes feeding behavior of hydra, shows detailed microscopy of stinging cells used in capturing prey, and reviews two digestive processes: cellular and extracellular. Also covers locomotion, reproduction by budding, the development of sex organs, and symbiotic guests, both external and internal.
Part of the "Branches on the Tree of Life" series. Begins with a series of observations on Hydra, including habitat, structure, feeding, nematocyst discharge, locomotion (by looping), and its sexual and asexual reproductive strategies. Obelia illustrates the two-stage life cycle found in many cnidarians. Examining the biology of jellyfish (class Scyphozoa), sea anemones, and corals (class Anthozoa) rounds out the overview of phylum Cnidaria.
The Tennessee Aquarium in Chattanooga is a unique freshwater aquarium. Visitors learn how a river is formed, how fish live beneath its surface, and other fish facts. Showcases important world rivers and their fish. Introduces aquarium workers, food preparation, the quarantine area, and a control center. Notes the aquarium is a learning place from top to bottom.
The lionfish is invading the Atlantic and Caribbean waterways with catastrophic results. This non-native species has no local predators and is propagating at a rate that adversely impacts the coral reef habitats of the Eastern United States, Caribbean, and South America. This is a story of communities banding together to ensure the protection of native species. Scientists and citizens are monitoring the situation, and high school marine biology students are studying the feeding behavior of this voracious predator.
Are humans the accidental products of an uncaring universe? Or are they the beneficiaries of a cosmic order that was planned beforehand to help them flourish? This documentary explores growing evidence from physics, chemistry, biology, and related fields that our universe was designed for large multi-cellular beings like ourselves. Geneticist and author Michael Denton investigates the special properties of carbon, water, and oxygen that make human life and the life of other organisms possible.
In biology, a chimera is a single organism whose body is made from parts of two or more genetically distinct individuals of the same species. Biological chimeras were once thought to be rare, but modern genetics has shown that these genetic mashups are more common than previously thought. Part of the "It's Okay to Be Smart" series. Please note this title discusses human reproduction.
Science laboratories present a whole range of potential hazards to people's health and well-being, and it is critical that both teachers and students are fully aware of their responsibilities to ensure the learning environment is kept safe at all times. Aims at viewers who are not new to science laboratories. Covers a range of safety areas, including general safety in these laboratories and specific areas of potential risk in chemistry, biology, and physics labs.
Every cell in the body is a specific size. Host Trace Dominquez discusses some new scientific findings related to cell growth. A team of biologists has zeroed in on a previously unknown mechanism within the cell growth cycle that controls cell size. They made this fundamental finding by studying yeast cells, but it could provide insight to basic human biology. Part of the "Uno Dos of Trace" series.
In this episode, host Emily Graslie interviews conservation scientist Dr. Lesley de Souza. She is working with the people of Guyana to establish a new protected area. Their goal is to safeguard a watershed for animals like the arapaima, one of the largest freshwater fish in the world. Part of "The Brain Scoop" series.
