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 ...

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 ...

Software lets researchers create tiny rounded objects out of DNA. Here’s why that’s cool. DURHAM, N.C. -- Marvel at the tiny nanoscale structures emerging from research labs at Duke University and ...

Johnson and Alistar competed as finalists in CU Boulder’s 2025 Lab Venture Challenge where their technology generated much interest from industry leaders. Access to DNA is crucial in many branches of ...

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 ...

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 ...
