It might seem like researchers give animals drugs just to make a good headline, but these experiments have taught scientists a lot.

Can we change the blueprints of life? This week we are exploring that question with genetic engineering. We’ll discuss how selective breeding can improve agricultural practices, and the potential DNA-level engineering could have on other...

In this enlightening, funny talk, Marlene Zuk shares just some of the ways that insects are truly astonishing -- and not least for the creative ways they have sex.

Join the Amoeba Sisters as they explain gene and chromosome mutations, and explore the significance of these changes. This updated video has improved audio and images! Codons and the amino acids they code for is represented by standard...

Paul Andersen explains how reproductive isolation can eventually lead to speciation. Three main barriers to gene flow are included: geographic, pre-zygotic and post-zygotic. Both allopatric and sympatric speciation are discussed. A...

Birds fly, and fish swim. We learn this when we are children. But not everything in nature is quite so simple… Meet Limacina helicina, an artic-dwelling sea butterfly that flies through the water.

This week, Dr. Shini Somara goes toe to toe with Hank in a battle of wits about fluid dynamics and life in space.

Sometimes trail blazers of science aren't famous like Darwin or Pasteur. Sometimes they're humble Abbots, just growing peas in the back of their Abbey. This is the story of Gregor Mendel and how his work was done, lost, then found again.

Paul Andersen explains aspects of genetics that were not covered by Gregor Mendel. He begins with the following topics; incomplete dominance, codominance, epistasis, multiple alleles, and multiple genes. He then explains how linked...

Scientists have learned more about why royal jelly makes queen bees, and we peek at the tiny and terrifying mandibles of trap-jaw ants.

Paul Andersen explains how linked genes behave and how linked genes were discovered. He shows how linked genes would be reflected in a dihybrid cross using a fruit fly simulator. He uses chromosome-based punnett squares to explain why...

Howcast - Don’t throw out that banana peel—or that overly ripe banana. Put them to good use around your house instead.

We can all agree that insects have heads, right? But what exactly do they have rattling around inside there? Do insects have brains like humans? Or is it just a bunch of nerves and goo? Well join Inés and Alie to get the answers and to...

This week on Nature League, Brit discusses the concept of model organisms and offers some arguments for and against their use. Get your Critically Endangered Sharks poster here! Only on sale through May 30th.

Syracuse University biologists are now able to study previously unobservable events tied to sexual selection. That's because they were able to genetically alter fruit flies so that the heads of their sperm were fluorescent green or red....
