Humans are a diverse lot. We can look distinctively different. But is that because of race or ethnicity?

Nearly every living cell is made of DNA, and every chromosome contains exactly one molecule of DNA. But not all cells are made of the same number of chromosomes.

It's easy to equate "Caucasian" with "white." But that one word — Caucasian — touches on issues much deeper than skin color.

Superhuman powers are rare, but some do exist. But what if scientists used gene manipulation to create humans with super strength and abilities in the future — like super soldiers?

What happens when twins are reunited decades later? And how in the world can you explain separated twins giving their firstborn son or their family dog the same exact name?

A NASA study of astronaut Scott Kelly showed that spending time in space altered the expression of some of his genes. But does being on a mountain cause similar effects?

In addition to the double-stranded spiral, a four-stranded tangle, known as an i-motif, has been shown to exist throughout our genetic material.

Tetragametic chimerism occurs when a single organism has two genetically distinct types of DNA.

Scientists in China successfully cloned the first-ever primates using the same method that created the world's most famous sheep — a method called somatic cell nuclear transfer.
