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 ...

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 ...

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 ...

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 ...

AMES, Iowa – Scientists have been making nanoparticles out of DNA strands for two decades, manipulating the bonds that maintain DNA’s double-helical shape to sculpt self-assembling structures that ...

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 ...

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 ...

Researchers at the University of Geneva have built a molecular system that can tell the difference between a cancer cell and a healthy one, then selectively destroy the tumor cell while leaving normal ...
