Genetics

Ever been caught in the crossfire of a wet dog firing droplets of water away from their fur with a mad shake? Well, they can't help it. Scientists have identified the innate sense-motor function mechanism that drives dogs to twist and spout.

Spanning nearly 100 laboratories in 45 countries, a landmark study has, for the first time, shown an association between genetic brain shape and size and the prevalence of neurological conditions such as Parkinson's disease and ADHD.

Treatment for irritable bowel syndrome, IBS, often includes restricting certain foods, such as carbohydrates, but that doesn’t work for everyone. A new study found that genetics might be the reason for this, opening the door to genetically tailored diets to treat IBS.

Gut bacteria that have been disrupted in infancy can lead to greater aggression later in life, including causing changes to aggression-related genes, according to a new study. It warrants further research into the link between the gut and brain.

A new gene therapy for Duchenne muscular dystrophy (DMD) has shown promise in not only slowing the progression of the disease but potentially even reversing the muscle damage, with human trials set to begin within two years.

Scientists have assembled the most complete woolly mammoth genome in 3D, thanks to an incredible “freeze-dried” specimen. With its DNA preserved in a glass-like state, chromosomes were found for the first time, and even gene expression patterns.

An amphibian has lived up to its name, swapping out its usual green coloring for bright blue, in the first-ever record of a magnificent tree frog with this appearance. It's stunned scientists, who know they're unlikely to see this again.

In pre-clinical trials, a small molecule effectively regrew neurons, reduced inflammation, and improved memory, speed, coordination, grip strength, and more. The finding could have a profound impact on aging and the diseases that accompany it.

Since Neanderthals' whole genome was sequenced, there’s been growing interest in how their genetics influences our health. New research has found that genetic variations derived from our ancient relatives are associated with an increased susceptibility to autism.

New research uncovering the DNA-damaging mechanism by which a mutated gene causes a rare, fatal disease may have repercussions for the treatment of many other diseases linked to aging, including heart disease, autoimmune disorders, and cancer.

Scientists have discovered the organism with the largest known genome. At 160 billion base pairs, it's 50 times bigger than the human genome, and the organism it’s describing is a tiny fern you wouldn’t even notice if you tripped over it on a hike.

The world's first human trial of a drug that can regenerate teeth will begin in a few months, less than a year on from news of its success in animals. This paves the way for the medicine to be commercially available as early as 2030.
