Brown cats are something of a rarity, but you may have something pretty close.

Hank talks about astrobiology - the study of and search for life in the universe off Earth. Right now, the field has more questions than answers, but all they all seek to answer that one fundamental query: are we alone in the universe?

Scientists are closely watching SARS-CoV-2 to track mutations and see if it's developed into different strains. So, has it?

Hank dishes out updates on the mutant flu virus and the James Webb Space Telescope, and gives us some new bits about new exoplanets, secret space planes, and a study that shows that music evolves according to Darwin's rules.

Energy drinks- you've had them, or at least you're well aware of their presence in today's culture. But what is actually in these things? Especially the mysterious ingredient TAURINE?

How did earth get the ingredients for life? A new discovery from Comet 67P might hold some answers. And learn where to find Mars in the night sky from 75 million kilometers away.

MSG, or monosodium glutamate, got a bad rap in the 1960s when people started complaining of "Chinese Restaurant Syndrome," but that bad reputation was fueled more by xenophobia than science. Turns out, it's just delicious.

Hank tells us how some gamers are outperforming sophisticated computer programs to help solve the puzzle of protein folding and to assist scientists in finding better treatments for HIV/AIDS, cancer, and Alzheimer's.

Join the Amoeba Sisters as they take a brisk "stroll" through their biology playlist! This review video can refresh your memory of major concepts, help you identify what you need to re-study, and reinforce vocab. Expand these details for...

After a polypeptide is produced in protein synthesis, it's not necessarily a functional protein yet! Explore protein folding that occurs within levels of protein structure with the Amoeba Sisters! Primary, secondary, tertiary, and...

How to Read a Codon Chart

Bacon and eggs aren’t a classic flavor combo for no reason, and the science behind why they taste so good together could help us make healthier foods more appealing to our palates.

Sugars aren’t just for munching and crunching, they also make up our genetic code! So what does it mean to find sugars INSIDE meteorites?

We are generally pretty confident when it comes to things that we know really well. But what if your brain is lying to you... tricking you into thinking you know everything, but you really know nothing?

Paul Andersen explains how biogeochemical cycling is used to move nutrients from the environment into living material and back again. He explains the water cycle, the carbon cycle, the nitrogen cycle and the phosphorus cycle. He also...

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 changes in the genotype of an individual can affect the phenotype. He begins with genotype:phenotype::letters:story analogy. He explains how mutations can be neutral, beneficial or harmful. He also explains...

Some of the animals you think of as just cute grass-eating creatures might actually be more interested in chomping on your meaty bones.

Hank talks about the molecules that make up every living thing - carbohydrates, lipids, and proteins - and how we find them in our environment and in the food that we eat.

Hank tells us the stories of three experiments in biology that, with creativity and luck, changed science & the world with it in their work to solve the mysteries of the universe.

Hank tackles another one of the internet's most-asked questions: What makes feet stink? And maybe more importantly, why do they sometimes smell like ... snack food?

Humans have relied on fertilizers to grow their plants for thousands of years. But the production of synthetic fertilizers also requires an immense amount of energy that comes primarily from fossil fuels and therefore contributes to...

Hank imagines himself breaking into the Hot Pockets factory to steal their secret recipes and instruction manuals in order to help us understand how the processes known as DNA transcription and translation allow our cells to build proteins.

You know what starvation is, but do you know what it does to you? Hank walks you through the three major metabolic phases of starvation, from burning sugars to, basically, self-cannibalism.
