A microbe's fountain of youth

The yeast S.pombe is one of the best-studied microbes in the world. First isolated from East African millet beer over a century ago, it's been used as a model organism in molecular and cell biology for the past sixty years. ...

Biologists simulate a cell in action

(Phys.org) —The inner workings of a cell involve hundreds of thousands of discrete molecules, engaged in a repeating cycle of interactions that sustain life.

Single cells: Same same but different

(Phys.org) —If half of a cell population were coloured white and the other half were coloured black, scientists should think all cells are grey. Conventional methods average over thousands of cells, overlooking any cell-to-cell ...

Biologists identify proteins vital to chromosome segregation

New York University biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division. Their findings shed new light on genome ...

Membrane fusion a mystery no more

The many factors that contribute to how cells communicate and function at the most basic level are still not fully understood, but researchers at Baylor College of Medicine have uncovered a mechanism that helps explain how ...

Lessons learned from yeast about human leukemia

The trifecta of biological proof is to take a discovery made in a simple model organism like baker's yeast and track down its analogs or homologs in "higher" creatures right up the complexity scale to people, in this case, ...

Cancer drug cisplatin found to bind like glue in cellular RNA

An anti-cancer drug used extensively in chemotherapy binds pervasively to RNA -- up to 20-fold more than it does to DNA, a surprise finding that suggests new targeting approaches might be useful, according to University of ...
