Study suggests catalyst for human brain evolution

More than a million years ago, large chunks of the human genome were rearranged—a chance event during egg or sperm formation that led to the deletion, duplication, or reversal of sections of DNA. Those structural variants, ...

DNA packaging supports cell division, finds study

The DNA molecule is located in the cell nucleus as a densely packed complex of DNA and protein, known as chromatin. Wrapped in sections around a core of special proteins known as histones, the DNA forms so-called nucleosomes, ...

Euchromatin is not really open in living cells, shows study

DNA and associated proteins in active regions of the genome are condensed but behave like a viscous liquid at the molecular level. This finding greatly increases our understanding of the physical nature of expressed genome ...

One of sunken warship Vasa's crewmen was a woman

When the human remains found on board the Swedish warship Vasa were investigated, it was initially determined that the skeleton designated "G" was a man. New research now shows that the skeleton is actually from a woman.

Can investigators use household dust as a forensic tool?

A North Carolina State University-led study has found it is possible to retrieve forensically relevant information from human DNA in household dust. After sampling indoor dust from 13 households, the researchers were able ...

Researchers uncover the first steps driving antibiotic resistance

Antibiotic resistance is a global health threat. In 2019 alone, an estimated 1.3 million deaths were attributed to antibiotic resistant bacterial infections worldwide. Looking to contribute a solution to this growing problem, ...

Their stories were lost to slavery. Now DNA is writing them

In the 1700s, a boy was born into slavery in Colonial America. He spent his life working in the coastal city of Charleston, South Carolina. And when he died in middle age, he was buried alongside 35 other slaves.
