Some researchers think mitochondria could be hiding the key to Alzheimer's disease. And we may have a new strategy to fight the threat that the global banana industry has been facing for decades.

The Gros Michel banana lost the battle with fungus in the 1950s, but was replaced by the Cavendish. This time we might not have a new banana to come to the rescue. Could this be the end of bananas? Hosted by: Hank Green

Paul Andersen explains how variation is created within a cell. He starts by showing how molecular variation can increase fitness at the local level. He explains how an additional chlorophyll molecule allows plants to absorb more light...

Welcome back to SciShow Quiz Show, where Hank goes head-to-head with Craig Benzine, better known as WheezyWaiter.

More detailed brain scans reveal that the brain is more complicated than we thought! And cloned sheep might be healthier than we thought!

Is the science of Orphan Black realistic? Could we clone humans, or engineer them to have customized traits? We take a look at today's genetic engineering technologies to find out if designer babies and human cloning is, or should be, a...

Salps are more than just strange balls of goo drifting through the sea—in fact, they’re more closely related to us than they are to jellyfish, and play a huge role in marine ecosystems and the global carbon cycle as the “vacuum cleaners...

At SciShow, we ask the tough questions. Today we explore the answer to the question "if identical twin brothers married identical twin sisters, would their offspring be identical?"

Hank gets into why sex is the preferred method of reproduction for most species - and it's not for the reasons you're thinking.

Fruit trees are unpredictable and grow slowly, and consumer tastes are fickle, so successful new varieties of fruit are rare

Paul Andersen starts with a brief description of asexual and sexual reproduction. He explains how meiosis ensures variation in the next generation. He describes the important structures in the male and female reproductive system. He...

In this video Paul Andersen explains how variation is created in a population over time. Variation in offspring is caused by genetic recombination, mutations and environmental effects. Parental DNA is recombined using the process of...

It sounds like something out of a sci-fi movie: a new crayfish population made entirely of asexually reproducing, all-female clones. But is it a new species?

We know how to clone animals, so why aren't we saving endangered species by cloning their populations?

If we were to write a fable to get this moral across, it would have to star the freshwater cnidarian called the hydra. Because in the hydra, the question of butts connects to the ambiguities of immortality, which in turn relates to the...

This video discusses the concept of cloning, explaining the different types of cloning and providing examples of cloned animals. It also addresses the misconception that clones always look identical, highlighting that while clones are...
