Researchers design first artificial ribosome

Researchers have engineered a tethered ribosome that works nearly as well as the authentic cellular component, or organelle, that produces all the proteins and enzymes within the cell. The engineered ribosome may enable the production of new drugs and next-generation biomaterials and lead to a better understanding of how ribosomes function.

Bracing up DNA

Researchers have revealed the mechanism of action of the 'back brace' proteins that stabilize single strands, protect them and prevent them from folding back into a double-helix structure that can inhibit subsequent DNA processing.

New material forges the way for 'stem cell factories'

Scientists have discovered the first fully synthetic substrate with potential to grow billions of stem cells. The research could forge the way for the creation of 'stem cell factories' - the mass production of human embryonic (pluripotent) stem cells.

Light-gated control of cell division

Chemists have developed photoresponsive derivatives of an antimitotic drug, which permit light-dependent control of cell division. The new agents could provide the basis for precisely targeted tumor therapies, free of side-effects.

Can scientists hack photosynthesis to feed the world as population soars?

Scientists attending a workshop at Cold Spring Harbor Laboratory slipped the leash of scientific caution and tried to imagine what they would do if they could redesign plants at will. The ideas they dreamed up may make the difference between full bellies and empty ones in the near future when population may outrun the ability of traditional plant breeding to increase yields.

New cell division mechanism discovered

Researchers have discovered that chromosomes play an active role in animal cell division. This occurs at a precise stage - cytokinesis - when the cell splits into two new daughter cells.
