Death does not make DNA disappear. Long after the heart has stopped and the brain has lost function, genetic material can remain inside cells and tissues. What changes is the environment around it: ...

How do bacteria adapt when resources run low? ISTA researchers have found that, under starvation stress, E. coli can use ...

More than two decades after scientists first sequenced the entire human genome — all 3 billion “letters,” or base pairs, of DNA code — the meaning of much of this code remains a mystery. While an ...

Why do human brains vary in size and shape, and how did our brains expand over evolutionary time to give us our enhanced ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

A record player-like microscope and computer simulations solve a longtime mystery, showing that metal ions bridge DNA strands ...

Ancestry DNA testing turns genetic science into an engaging English lesson, explaining how DNA comparisons can reveal family ...

Why a study of 1.14 million people produced opposite headlines from the same paperAt the beginning of September, a paper was ...

A study found 55 DNA methylation regions differed in pediatric MS, with Epstein-Barr virus infection emerging as the top-ranked pathway.

Chemosynthetic bacteria have been documented in various marine environments and in association with invertebrate hosts such ...

Genetic features known as transposons make up a large portion of many mammalian genomes, including humans', and they are now known to play a variety of roles. Some transposable elements (TEs) could be ...
