Genetics

The existence of orange cats dates back to the 12th century, but the DNA driving this color has been a mystery – until now. Scientists have solved the puzzle, finding a surprise variant that triggers ginger fur, one not seen in any other orange animal.

Why do elephants, one of the biggest animals on the planet, paradoxically experience unusually low rates of cancer? The question has led scientists to discover these remarkable mammals carry unique genetic variants that reduce their risk of tumors.

Researchers have genetically modified spiders for the first time using the CRISPR gene-editing process. Adding a single gene to unfertilized eggs resulted in the creation of a spider that could produce red, fluorescent silk.

Like a plot mashup of Jurassic Park meets Game of Thrones, John Hammond meets Jon Snow, scientists at Colossal Biosciences claims to have pulled off the world's first de-extinction event. It's brought back the dire wolf.

You don't often find crowds flocking to take in the pungent scent of rotting flesh, yet that's just what happens when a corpse flower blooms at a public garden. But this iconic endangered plant is now facing a new threat – our aversion to paperwork.

A long-term trial has found that a discontinued drug halved the onset of a genetic form Alzheimer's, from all but 100% to 50%. Buoyed by the results, scientists are now trialing anti-amyloid medication as a preventative for all types of the disease.

Researchers at the University of Cambridge have identified a bunch of genes linked to obesity in dogs – and found the very same ones in humans predisposed to putting on weight too.

Scientists have identified new gene modifications that can make tomatoes and eggplants grow bigger, which could help boost yields in developing countries.

The quest to resurrect the woolly mammoth has taken another step forward, with the creation of the Colossal Woolly Mouse. The lab-made rodents have been genetically altered to possess key physical traits of the extinct beasts – in fur and fat, at least.

Scientists in the UK have successfully used gene therapy to restore some vision to legally blind children with an inherited retinal condition. All 11 children in the clinical trial saw improvements within weeks of a single surgical treatment.

Built to be carnivorous, giant pandas spend up to 16 hours a day on their backsides eating bamboo. But contrary to all the panda jokes, it's not because they're lazy or too dumb to know better. It's far more fascinating – and it may help humans, too.

Spinal muscular atrophy is a debilitating genetic condition that’s usually fatal by a few years of age. But an intriguing case study might demonstrate a simple new treatment, with a child showing no signs at all two and a half years after birth.
