New Double Helix Visualization Revises What We Know About DNA

By using an advanced microscopy technique, researchers have collected the most precise measurements to date of DNA's tangled structure. Their results showed significant variations to the well-known double helix — variations that are offering fresh insights into the inner workings of this life-bearing molecule. » 5/16/14 3:20pm 5/16/14 3:20pm

Science and everyday life cannot and should not be separated

Today we celebrate the birthday of Rosalind Franklin, the unsung heroine who discovered DNA's double helical structure. To that end, we present the following quote, taken from a letter to Rosalind's father, wherein she weighs in on the perennial debate over science and its ability to either elevate or diminish our… » 7/25/13 2:42pm 7/25/13 2:42pm

Quadruple helix DNA found in living human cells — and it may be linked to cancer

The double helix DNA structure is about as iconic as its gets. But geneticists have long speculated about the potential for a quadruple helix to exist — a four-stranded DNA structure. And indeed, computer models and lab experiments have suggested that it's theoretically possible. » 1/21/13 8:00am 1/21/13 8:00am

Scientists snap a picture of DNA’s double helix for the very first time

For the last 60 years, scientists have known that DNA's structure is composed of a spiraling corkscrew. They know this thanks to molecular theory and and an old-time technique called X-ray crystallography, where patterns of dots are converted into an overarching image using mathematics. But now, using an electron… » 11/29/12 9:45am 11/29/12 9:45am
