Scientists have tracked down an elusive 'tangled knot' of DNA

It's DNA, but not as we know it. In a world first, Australian researchers have identified a new DNA structure—called the i-motif—inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside ...

Programming DNA to deliver cancer drugs

DNA has an important job—it tells your cells which proteins to make. Now, a research team at the University of Delaware has developed technology to program strands of DNA into switches that turn proteins on and off.

What is CRISPR gene editing, and how does it work?

You've probably read stories about new research using the gene editing technique CRISPR, also called CRISPR/Cas9. The scientific world is captivated by this revolutionary technology, since it is easier, cheaper and more efficient ...

Biophysicists unravel exact folding of a single gene

The way genes are folded determines their activity in our body. Leiden University biophysicists are now the first to unravel this structure molecule-by-molecule. Publication on December 1st in Nature's Scientific Reports.

Expanding DNA's alphabet lets cells produce novel proteins

Scientists are expanding the genetic code of life, using man-made DNA to create a semi-synthetic strain of bacteria—and new research shows those altered microbes actually worked to produce proteins unlike those found in ...

Chromosome organization emerges from 1-D patterns

The DNA in a human cell is 2 yards (1.83 meters) long and wraps around millions of bead-like histone proteins to fit inside the cell's nucleus. Researchers at Rice University and Baylor College of Medicine showed that examining ...

Secrets of the amazing tardigrades revealed by their DNA

New genome sequences shed light on both the origins of the tardigrades (also known as water bears or moss piglets), and the genes that underlie their extraordinary ability to survive in extreme conditions. A team of researchers ...

New technique enables safer gene-editing therapy using CRISPR

Scientists from The University of Texas at Austin took an important step toward safer gene-editing cures for life-threatening disorders, from cancer to HIV to Huntington's disease, by developing a technique that can spot ...
