DNA

Scientists have not just found a new way that aging cells drive inflammation, but have also blocked it from happening with an existing FDA-approved drug. This opens the door to an entirely new way to shield the body from age-related health decline.

One of the world's oldest turds has been given the royal science treatment, with ancient Arctic ground squirrel droppings offering a smorgasbord of DNA from other animals and plants dating back up to 700,000 years.

The rules of biology have been torn up by a small fish in the Pacific that steals light-producing molecules it from its food to make it bioluminescent, providing an "invisibility cloak" it needs for protection. It's the only example of kleptoproteinism we know of.

Your next favorite true crime podcast might have some new forensics jargon to make sense of. Researchers in Australia have developed a new way to identify humans – similar to how we do with DNA – that could come in handy while investigating crimes.

For the first time, scientists have demonstrated how tanning beds cause fundamental DNA damage across almost the skin's entire surface that results in a threefold risk of developing melanoma. It puts beyond doubt the dangers of using these devices.

Most pet dogs carry a little wolf inside them; tiny snippets of wolf DNA that slipped into dog genomes after domestication. Now a new study has found almost two-thirds of dog breeds have a small amount of wolf genes, including some breeds you wouldn't expect.

See how scientists can now watch DNA repair in real time. A new glowing sensor developed at Utrecht University reveals how cells fix double strand breaks live.

After two decades in the making, scientists have cracked the code on a drug that can repair DNA, setting the scene for a new class of therapeutics that can fix tissue damage that occurs through heart attack, inflammatory disease and other conditions.

Scientists have sequenced RNA from a nearly 40,000-year-old woolly mammoth leg, the oldest ancient RNA ever recovered. These fragile molecules could reveal which genes were active in the animal’s final hours.

An ambitious plan to generate sequence genomes for 1.85 million species on our planet is underway. It's a major undertaking that'll dramatically enhance our understanding of biology, and inform conservation efforts. Thankfully, AI is lending a hand.

A new gene-editing technique from the University of Texas at Austin uses bacterial retrons to replace entire sections of dangerously mutated DNA with healthy genetic code. It could "reno" multiple mutations simultaneously.

One of the first events to signal the collapse of Napoleon's reign was his crushing defeat after an invasion of Russia in 1812. Researchers have long thought that the disease typhus played a role, but modern DNA analysis paints a different picture.
