In 1643, Johann Wirsung was shot and killed outside his home, but not before he named one of the men responsible. One rumor that has emerged over the years is the man was paid by one of Wirsung's former assistants, who claimed Wirsung...

In the search for the genes that make us human, some of the most important answers were hiding not in the genes themselves, but in what was once considered genomic junk.

Earlier this week, a team of researchers announced that they’d made a discovery about how we inherit mitochondrial DNA from our parents that could change what we know about not only disease inheritance, but human history as a whole.

Biologist Dan Gibson edits and programs DNA, just like coders program a computer. But his "code" creates life, giving scientists the power to convert digital information into biological material like proteins and vaccines. Now he's on to...

Inspired by an abalone shell, Angela Belcher programs viruses to make elegant nanoscale structures that humans can use. Selecting for high-performing genes through directed evolution, she's produced viruses that can construct powerful...

Paul Andersen shows you how to compare DNA sequences to understand evolutionary relationships. He starts with a brief introduction to cladograms and evolutionary relationships. He shows you how to classify DNA relationships using a...

Epigenetic inheritance is really weird, but is it real?

Mismatch repair (MMR) is a DNA repair mechanism that corrects base-pairing errors and small insertions or deletions that escape proofreading during DNA replication. A protein complex identifies the mismatch, excises a section of the...

The video contains tricks to easily remember point mutations

A group of South Korean scientists has developed an innovative DNA barcode system that can be sprayed onto consumer products, replacing traditional barcode stickers. This breakthrough technology provides a secure and tamper-proof method...

Evolution is the net change in organisms or a population over the span of many generations. This change in organisms or populations happens through DNA mutations and reconbination and is passed down to the next generation through...

Dr. Andy Feinberg and Dr. Steve Platts discuss the history and details behind the Twins Study. The experts reveal some of the findings from the multi-year endeavor packed with 10 different investigations. HWHAP Episode 87.

In this video, I will show you how to design primers to amplify the entire gene during a routine PCR.

This video explains one of the most basic forms of classification, which is the logistic regression model.
