DNA

Sequencing mammoth DNA has already helped scientists map out how these Ice Age giants evolved, migrated, and survived. But there's a hidden layer of history still waiting to be decoded – the microbes that lived inside them.

A groundbreaking discovery reveals how HIV integrates its genetic material into human DNA, exposing a key viral vulnerability that could lead to new therapies and bring the world closer to a functional HIV cure.

In a groundbreaking study, scientists have mapped the most detailed genetic blueprint yet of frailty – the age-related decline that affects around 40% of people aged 65 and over. It provides new hope for developing precision anti-aging therapies.

A species loved by scientists has a new trick under its wings – a "time out" in youth that leads to significantly slower aging throughout life. This discovery, which shows that biological aging isn't fixed, is a breakthrough in human longevity science.

A groundbreaking study has revealed that white sugar doesn’t just feed bacteria in the gut – it rewires them. Consuming sugar can trigger physical flips in bacterial DNA, setting off a chain reaction that alters immune responses and gut health.

Humans have been getting infected by ancient bacteria and viruses for at least 37,000 years. Now, for the first time, pathogen DNA has uncovered a pivotal disease "turning point" that happened 6,500 years ago, which would forever change our lives.

Taking a vitamin D supplement can knock years off your biological aging, according to the results of a large, long-term study. This may not seem like a lot, but it's a significant amount as you become increasingly susceptible to disease as you age.

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.

A new study is presenting a radical new theory of aging, suggesting two competing theories are actually intertwined. And even more controversially, the billions of dollars being invested in anti-aging treatments may be targeting the wrong mechanism.

Researchers at UCSF have developed a single genomic test that can quickly detect virtually any kind of pathogen in a patient. This allows for much quicker diagnoses, enables targeted treatment to begin sooner, and could lower healthcare costs.

Gathering genetic material from treetops in tropical rainforests would be a near-impossible task to perform safely by hand. That's why scientists have developed a system that allows a drone to do the job, without even touching the trees itself.

Bizarre clumps of organic matter found buried alongside Bronze Age mummies in China have now been identified as cheese. New DNA analysis has finally solved a long-standing mystery, and it makes it the oldest cheese ever found, dating back 3,600 years.
