Building a DNA nanoparticle to be both carrier and medicine

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 could someday have jaw-dropping medical ...

Using computer-engineered DNA to study cell identities

All the cells in our body have the same genetic code, and yet they can differ in their identities, functions and disease states. Telling one cell apart from another in a simple manner, in real time, would prove invaluable ...

Newly identified protein helps flowers develop properly

Flowers rely on a newly identified protein to develop properly with all of their organs, according to the research team who made the discovery. The team, led by Penn State biologists, identified the protein in the model plant ...
