Researchers have identified elusive DNA switches in brain support cells that influence genes tied to Alzheimer’s disease. When people think about DNA, they often picture genes that determine our ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ...

Researchers analyzed 333 Italian centenarians and compared their genetic composition to 103 ancient genomes to investigate ...

Polar bears are changing at a genetic level in response to climate change. This is what it means for the rest of the Arctic.

Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple loop at the cell’s center. A giant microbe called Thiovulum imperiosus has now ...

Structures long blamed for blocking genes actually help them turn on, according to the Cornell Chronicle. Cornell scientists found that nucleosomes — the spools that package DNA — relieve twisting ...

Now, researchers at UNSW Sydney have discovered a group of these switches that help control how brain cells called astrocytes ...

Estrogens, the main female sex hormone, although they also perform some functions in men, are involved in a myriad of processes, which is why the body changes so much during menopause. This is because ...

Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to ...

In genetics, scientists must analyze the genomes of millions, if not billions, of people, each carrying millions of variants. It’s an unfathomable amount of data. Which leads us to another central ...

It's a common storytelling trope: the stubborn foe who is eventually revealed to be a much-needed friend. Biology has its own ...

Rare case shows a man living virus free for years after stopping treatment, raising new questions about how the immune system ...
