This animation depicts the CRISPR-Cas9 method for genome editing - a powerful new technology with many applications in biomedical research, including the potential to treat human genetic disease. Feng Zhang, a leader in the development of this technology, is a faculty member at MIT, an investigator at the McGovern Institute for Brain Research, and a core member of the Broad Institute. Further information can be found on Prof. Zhang's website at http://zlab.mit.edu .

Want to know how much bacteria we host within our body and how many we encounter on a daily basis well check out this clip from Life On Us where we will see the different types of bacteria that inhabit us like Demodex Folliculorum which is a face mite...

4:51 video What's tasty, abundant and high in protein? Bugs! Although less common outside the tropics, entomophagy, the practice of eating bugs, was once extremely widespread throughout cultures. You may feel icky about munching on insects, but they feed about 2 billion people each day (Mmm, fried tarantulas). They also hold promise for food security and the environment. Emma Bryce makes a compelling case for dining on bugs.

Would you rather be bitten by a venomous rattlesnake or touch a poisonous dart frog? While both of these animals are capable of doing some serious damage to the human body, they deliver their dangerous toxins in different ways. Rose Eveleth sheds light on the distinction between poison and venom (and why you shouldn't treat either one like you've seen in the movies).

4:43 video Cancer usually begins with one tumor in a specific area of the body. But if the tumor is not removed, cancer has the ability to spread to nearby organs as well as places far away from the origin, like the brain. How does cancer move to these new areas and why are some organs more likely to get infected than others? Ivan Seah Yu Jun explains the three common routes of metastasis. 

It's hard to escape childhood without racking up a few scars. Why do these leftover reminders of a painful cut or crash look different from the rest of our skin? And why do they stick around for so long after the incident that caused them? Sarthak Sinha explains how scars form.

Hear from some of the country's leading scientists and medical experts who talk about why animal research is critical for medical progress and the advancement of both human and animal health.

This 22 min video provides insight into the benefits of bioscience research and the important role laboratory animals play in the scientific process. It introduces viewers to four people age 55 and older who have benefited from medical advances made possible by years of animal-based research. Viewers also meet four scientists who are helping make these advances a reality

4:32 video Dr. Debbye Turner Bell profiles one 7-year-old Virginia boy who has found a creative way to improve the lives of countless Epilepsy patients and seizure sufferers.

Behind every fart (and poop) is an army of gut bacteria undergoing some crazy (and crazy useful) biochemistry. Learn what they have in common with beer brewing, and why we'd want to know about this science anyway...

A simple animation explaining what Turner Syndrome is, how it is caused, the symptoms, and how it is diagnosed and treated. We hope this video will be useful to you and those around you.

You've always been told sugar is bad for you, but how bad is it really? Find out in this science music video - researched, written, sung, directed, shot, and edited by 8th graders from The Nueva School in California. This song is a science parody of "Sunday Candy" by Donnie Trumpet & The Social Experiment, featuring Chance the Rapper and Jamila Woods.

7:41 Explores classification in biology as well as taxonomy hierarchy: domain, kingdom, phylum, class, order, family, genus, and species with The Amoeba Sisters! This video also discusses the importance of scientific names and why classification can have major changes due to DNA and cell structure evidence.

Analogy of organizing music for taxonomy, then works through classification for humans.

New research shows our DNA is absolutely loaded with... NOTHING. 98 percent of our DNA plays no role in our development. But as Trace learns, the findings may not be so black and white.

We've harnessed electricity, sequenced the human genome, and eradicated smallpox. But after billions of dollars in research, we haven't found a solution for a disease that affects more than 14 million people and their families at any given time. Why is it so difficult to cure cancer? Kyuson Yun explains the challenges.

The Amoeba Sisters explain enzymes and how they interact with their substrates. Vocabulary covered includes active site, induced fit, coenzyme, and cofactor. Also the importance of ideal pH and temperatures for enzymes are discussed.

2:00 video It's not the Y chromosome itself that determines whether a baby is male or female, but rather a particular region called the SRY gene.

I'm sure you've probably heard of at least a few invasive species. Maybe you've heard of the Cane Toad. It's one of the classic introductions of invasive species gone wrong. It was introduced to eat pests in cane fields and then turned into a plague of epic proportions in Northern Australia. But here is the question. Now that these species are here, is it worth fighting their spread, or should we spend time and effort on other things. It's worth asking, and not just for the ethical implications. We live in a modern world and I think there is a real financial element to this as well. See if you can follow my logic through this video short. Do you agree with my thoughts? Should we keep fighting? Do you have any personal experience with an invasive species?
