Scientists at CSHL uncover new RNA processing mechanism and a new class of small RNAs

A very small fraction of our genetic material--about 2%-- performs the crucial task scientists once thought was the sole purpose of the genome: to serve as a blueprint for the production of proteins, the molecules that make cells work and sustain life. This 2% of human DNA is converted into interm...

Scientists at CSHL discover mobile small RNAs that set up leaf patterning in plants

Cold Spring Harbor, N.Y. -- A key item in the developmental agenda of a plant leaf is the establishment of an axis that makes a leaf's top half distinct from its bottom half. This asymmetry is crucial for the leaf's function: it ensures that the leaf develops a flattened blade that is optimized fo...

Senescence in liver cells is found by CSHL scientists to help limit acute tissue damage

Although post-reproductive life in humans is often associated with decline and a loss of powers, an analogous state in certain cells -- called senescence -- is proving to be one of ironic potency.
