Artificial DNA letters beyond A, T, G, C break a fundamental pairing rule to produce nanostructures with new shapes, far greater durability, and an unexpected ability to self-sort.

Using an atomic force microscope tip as a pen and different single-stranded DNA as inks, scientists at Northwestern University have demonstrated a technique that could lead to the ultimate ...

Scientists are turning DNA into tiny robots that can move, sense, and deliver drugs, pushing nanotechnology closer to ...

Big-picture patterns of DNA packaging, gene activation and mutations could hold the information needed to develop a blood-based biopsy for small cell lung cancer patients, according to new work ...

Marvel at the tiny nanoscale structures emerging from labs, and it's easy to imagine you're browsing a catalog of the world's smallest pottery: itty-bitty vases, bowls, and spheres. But instead of ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Brains are the quintessential decision-makers, gathering and weighing information before choosing a path forward. But in the natural world, many simpler systems accomplish similar tasks. Cells use ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...
