Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades - YouTube - 0 views

  •  
    The short film opens with two questions: "So what determines how many species live in a given place? Or how many individuals of the species can live somewhere?" The research that provided answers to these questions was set in motion by key experiments by ecologists Robert Paine and James Estes. Robert Paine's starfish exclusion experiments on the coast of Washington state showed that removing starfish from this marine ecosystem has a big impact on the population sizes of other species, establishing the starfish as a keystone species. James Estes and colleague John Palmisano discovered that the kelp forest ecosystems of the North Pacific are regulated by the presence or absence of sea otters, which feed on sea urchins that consume kelp. These direct and indirect effects of sea otters on other species describe a trophic cascade. These early studies were the inspiration for hundreds of investigations on other keystone species and trophic cascades, as well as ongoing studies into the regulation of population sizes and species numbers.

Transforming Ocean Trash Into Beautiful Art - YouTube - 0 views

  •  
    In the past, sailors on whaling ships would carve whale teeth into works of art in a process called scrimshaw. These pieces would be brought home to loved ones as mementos of the voyage. Design incubator Studio Swine is attempting to recycle found materials and turn this aged art form into a more sustainable practice. In this short film, travel to remote parts of the ocean, where "the closest people are in a space station," and watch as the process of collecting ocean trash and transforming it into beautiful treasure unfolds.

Cancer Discovery Activities | HHMI BioInteractive - 0 views

  •  
    Students begin by watching the online video clip and completing a worksheet. After that assignment, instructors can decide which of the two activities (or both!) to use in class. In Activity 1, students identify the locations on chromosomes of genes involved in cancer, using a set of 139 "Cancer Gene Cards" and associated posters. In Activity 2, students explore the genetic basis of cancer by examining cards that list genetic mutations found in the DNA of actual cancer patients. Small-group work spurs discussion about the genes that are mutated in different types of cancers and the cellular processes that the affected genes control. The Activity 1 and 2 Overview document provides short summaries of the two activities along with key concepts and learning objectives, background information, references and rubrics, and answers to students' questions. Both cancer discovery activities are appropriate for first-year high school biology (honors or regular), AP and IB Biology. Activity 2 is also appropriate for an undergraduate freshman biology class.

Your Microbiome Extends in a Microbial Cloud Around You, Like an Aura - 0 views

  •  
    In short, you have an aura, except it isn't made of purplish light; it's your personal cloud of dead skin cells, fungus and many, many microbes. And researchers are learning to be able to identify you by it.

Overweight mothers give birth to biologically older babies | New Scientist - 0 views

  •  
    Women who are overweight while pregnant are more likely to have babies who are biologically older than those born to women of a healthy weight. This could put the babies at a higher risk of developing chronic diseases later in life, and may reduce their life expectancy. Our biological age is linked to the length of our telomeres - bits of DNA that cap the ends of our chromosomes. Our telomeres shrink every time our cells divide, and continue to shorten throughout life. "Short telomeres have been associated with cardiovascular disease, type 2 diabetes and atherosclerosis," says Tim Nawrot at Hasselt University in Belgium.

NOVA: Gross Science Collection | Classroom Resources | PBS LearningMedia - 0 views

  •  
    Why do we smell different when we're sick? Why does cheese smell like feet? Why don't vultures get sick from eating rotting meat? Science is filled with stories: some of them are beautiful and some of them are gross. Really gross. Gross Science, a YouTube series hosted by Anna Rothschild, tells bizarre stories from the slimy, smelly, creepy world of science. In this collection, you'll find original short-form videos and DIY experiments from Gross Science, which is produced by NOVA and PBS Digital Studios. Learn about amphibians that eat their mother's skin, strange uses for bacon, how poop can be used to cure an infection, and more gross science topics.

The Dangers of Deicing - National Center for Case Study Teaching in Science - 0 views

  •  
    Loss of species richness is often due to anthropogenic activity. The global decline of amphibians is one such example. This case study examines the impact of road deicing agents on amphibians living near bridges and roads treated heavily with salt during the winter months. Concepts explored in this case include changes to the aquatic environment as a result of road deicing applications, bioaccumulation, osmoregulation in amphibians living in clean freshwater, and the impact of increased aquatic salinity levels on the ability of amphibians to adequately osmoregulate in an environment for which they are not adapted. Three short videos created by the author can be shown in class or assigned for viewing in advance for a "flipped" classroom approach. Originally developed for a general education/introductory biology course, the case could also be used with introductory level animal anatomy and physiology courses as part of a deeper exploration of the renal system.

Introduction to the Characteristics of life - YouTube - 0 views

  •  
    "A short 3.6 minute visually stunning introductory trailer choreographed to powerful music that introduces the viewer/student to the characteristics that all life on Earth shares. I made this for use by teachers of Biology and the Life Sciences as a motivational introduction to the wonders of life and the amazing characteristics that we all possess. As a High School Biology teacher myself, I have found these videos a great way to capture student interest immediately."

When a Gene Turned Off Is a Matter of Life or Death - National Center for Case Study Te... - 0 views

  •  
    When Jordan is diagnosed with brain cancer (glioblastoma multiform), his college plans are unexpectedly put on hold. This scenario is presented in order to teach students about gene regulation, as the efficacy of the drug Jordan receives for post-surgical treatment is dependent upon the activity level of a gene encoding a protein involved in DNA repair. This "flipped" case study requires students to prepare in advance outside of class by watching several short videos that have been selected to teach the basics of how cancer forms as well as the role of epigenetics in gene silencing. Inside of class, the case is delivered using progressive disclosure format in which students gradually receive additional information to answer a series of directed questions. To determine a treatment plan for Jordan, students analyze data from a research study involving patients treated for his specific type of cancer. The case is designed for advanced high school biology classes as well as lower-level undergraduate general biology courses for non-majors and majors.
