Most microscopes can only illuminate objects down to a certain size before tiny features blur together. This blurring is known as the diffraction limit of light. Super-resolution imaging techniques, ...

Scientists often describe life as a series of chemical reactions. Pallav Kosuri, Ph.D., describes life as movement. Chemical ...

Thymine modified polymer for delivering DNA into cells. A thymine modified compound, poly (ethylene glycol) (PEG), is bound to DNA through an annealing process, then delivered by intramuscular ...

Among the toughest animals ever discovered is a creature so small that a dozen could line up across the width of a grain of ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

In one sentence: DNA origami is a self-assembly technique that folds a long single-stranded DNA molecule into precisely defined nanoscale shapes using hundreds of short, computer-designed staple ...

In 1952, Alfred Hershey of Cold Spring Harbor Laboratory and his lab technician, Martha Chase, wanted to confirm that DNA was the carrier of genetic information. They tagged the protein coating of ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...
