Molecule stops DNA replication in its tracks

The process is akin to unzipping a zipper: The sliding clamp works its way along the DNA double helix while a network of proteins work together to unwind the two strands. Proteins known as polymerases then add, in assembly-line fashion, nucleotide bases — the building blocks that make up DNA — t...

Study specifies chemical pathways for ions through cell membrane

Life ultimately depends on the traffic of tiny charged particles through porous proteins studding the membrane surrounding every cell. In research published in Nature, scientists at The Rockefeller University have for the first time mapped a stepping-stone pathway of amino acids that these charge...

Newly identified cells make fat

To understand where fat comes from, you have to start with a skinny mouse. By using such a creature and observing the growth of fat after injections of different kinds of immature cells, Rockefeller University scientists have discovered an important fat precursor cell that may in time explain how...

Scientists identify a molecule that coordinates the movements of cells

Even cells commute. To get from their birthplace to their work site, they sequentially attach to and detach from an elaborate track of exceptionally strong proteins known as the extracellular matrix. Now, in research to appear in the October 3 issue of Cell, scientists at Rockefeller University s...

A DNA-based vaccine shows promise against the avian flu

Though it has fallen from the headlines, a global pandemic caused by bird flu still has the United States’ Centers for Disease Control and Prevention on high alert. Yet, to date, the only vaccines that have proven even semi-effective are produced in chicken eggs, take five to six months to prepar...

New formula predicts how people will migrate in coming decades

Nearly 200 million people now live outside their country of birth. But the patterns of migration that got them there have proven difficult to project. Now scientists at Rockefeller University, with assistance from the United Nations, have developed a predictive model of worldwide population shift...
