You Could Have a Secret Twin (But Not The Way You Think)
While searching for a kidney donor, Karen Keegan stumbled upon a mystery. After undergoing genetic testing, it turned out that some of her cells had a completely different set of genes from the others. And this second set of genes belonged to her twin sister— who had never been born. How did this happen? Kayla Mandel Sheets explores the condition known as chimerism.
Why Y Chromosomes Won’t Be Around Forever
We're generally taught that chromosomes determine an animal's sex, but it is way more nuanced than that.
We Skipped Flu Season. That's Bad
Some experts feared we were in for a "twindemic" during the 2020-2021 flu season. That didn't happen, which might mean that there will be more people susceptible to getting sick this year.
How Humans Became (Mostly) Right-Handed
No other placental mammal that we know of prefers one side of the body so consistently, not even our closest primate relatives. But being right-handed may have deep evolutionary roots in our lineage. And yet, being a leftie does seem to come with some unexpected advantages.
The Curious Case of Pigeon Beaks
Centuries of interbreeding taught early pigeon fanciers that beak length was likely regulated by just a few heritable factors. Yet modern geneticists have failed to solve Darwin’s mystery by pinpointing the molecular machinery controlling short beaks—until now.
How Neanderthal Are You? Tracing Our Genetic Ancestry
Scientists examining the evolutionary history recorded within our DNA are uncovering the global human story in greater detail. Watch the film to discover what DNA analyses taught six well-known figures, Maggie Aderin-Pocock, Clive Anderson, Bill Bailey, Kevin Fong, Alice Roberts and Sian Williams about their genetic ancestry.
The Island of the Last Surviving Mammoths
The Wrangel Island mammoths would end up being the final survivors of a once widespread genus. In their final years, after having thrived in many parts of the world for millions of years, the very last mammoths that ever lived experienced what’s known as a mutational meltdown.
Can CRISPR Cure Sickle Cell Disease?
Sickle cell disease is one of the most common genetic conditions worldwide, with more than 6 million people living with the disease. This video discusses the potential of CRISPR–Cas9 gene editing as a tool to cure this chronic condition.
NEW CentoXome - Turning Years Into Days
It takes approx. 7 years to diagnose a patient with a rare disease. With NEW CentoXome®, we can turn those years into days
Meet Dragon Man, Humans’ Possible New Relative
In a bone-filled week, a rediscovered cranium from China might represent an entirely new species of human that's possibly our closest evolutionary relative. And, while studying a 5,000-year-old skeleton, scientists found evidence of what might be the earliest plague infection.
