Indiana University researchers have shown how to identify tens of thousands of genes all at once by using tiny semiconductor crystals that dazzle in ultraviolet light. The technique works like a bar ...

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location ...

For decades, biologists have known that the instructions for life are written in DNA, yet the vast majority of those letters seemed to sit in the dark, doing little that was obvious. Now a new ...

Visualize, if you will, a group of bacteria cells. They are kind of silly looking, when you get right down to it: shaped like a sphere or a pill, sometimes covered in tiny hairs or spikes. While ...
