New microscopy method breaks color barrier of optical imaging

Researchers at Columbia University have made a significant step toward breaking the so-called "color barrier" of light microscopy for biological systems, allowing for much more comprehensive, system-wide labeling and imaging ...

Scientists use light to control the logic networks of a cell

Proteins are the workhorse molecules of life. Among their many jobs, they carry oxygen, build tissue, copy DNA for the next generation, and coordinate events within and between cells. Now scientists at the University of North ...

The spark that created life

Evolution by Darwinian natural selection is immensely powerful—both in nature and within laboratories. Using 'laboratory evolution', we can take an enzyme which combines random mutations and functional selection, and improve ...
