Growth in the sea comes down to a struggle for iron

...ut into a long, narrow strip. The major night-time task was to steam in crisscrossing transects to re-do the map of the patch because of this rapid change," says Wells. The two vessels worked together in the patch for 12 days but operated independently most of the time. New security guidelines prohibit s...

New binding target for oncogenic viral protein

...controls. Simian virus 40 (SV40) accomplishes this task by producing the highly oncogenic large T antigen. This protein corrupts the cellular checkpoint mechanisms that guard cell division and the transcription, replication and repair of DNA. T antigen also inactivates some of the most important proteins ...

Timing is everything: First step in protein building revealed

...ery what,when, where, why, who and how is no small task -- roughly 27 bits likeeIF1 play a role at one point or another. To tackle the problem, Lorschand his colleagues move between "timing" studies of the ribosome'smolecular comings and goings, and genetic studies that create mutantribosome parts, which ...

Scientists rid stem cell culture of key animal cells

...w and sustain stem cells through the tedious daily task of generating mouse feeder cells from mouse embryos. Feeder cells, or fibroblasts, are connective tissue cells that form the matrix upon which stem cells grow. The mouse feeder cells were an important ingredient in the mix of culture materials requi...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

... them with a huge amount of data, and the daunting task of deciphering what it means in terms of how genes function. For that part of the project, they teamed with investigators from the Broad (pronounced to rhyme with "road") Institute. "The human genome still has many surprises lurking within it," comm...

MSI releases 'moleculizer' - a new approach to simulation of intracellular biochemical networks

Tiny scaffolding allows stem cells to become working fat cells

...t, the cells were able to absorb lipids a hallmark task of fat cells. Researchers were able to extract RNA from the cells, just as they can from naturally occurring fat cells, and from that proved that the cells expressed the normally expected array of genes, and subsequent proteins and did so as well as...

Agilent Technologies releases automated literature search tool for biology researchers
