New tool could help reshape the limits of synthetic biology

Yeast geneticists report they have developed a novel tool - dubbed the 'telomerator' - that could redefine the limits of synthetic biology and advance how successfully living things can be engineered or constructed in the laboratory based on an organism's genetic, chemical base-pair structure.

Getting more out of nature: Genetic toolkit finds new maximum for crop yields

Scientists have found a new way to dramatically increase crop yields. The team has discovered a set of gene variations that boost fruit production in the tomato plant by as much as 100 percent. Plant breeders will be able to combine different gene variants to create an optimal plant architecture for particular varieties and growing conditions. The set will enable farmers to maximize yield in tomatoes and potentially other flowering plants, including crops like soybeans.

Cell division, minus the cells

Researchers have reconstituted cell division - complete with signals that direct molecular traffic - without the cell. Combining frog-egg extracts with lipid membranes that mimic the membrane of the cell, they built a cell-free system that recapitulates how the cleavage furrow is assembled.

The man with a thousand brains

Forty million people worldwide are living with Alzheimer's and this is only set to increase. But tiny brains grown in culture could help scientists learn more about this mysterious disease - and test new drugs.

Biology meets geometry

Architecture imitates life, at least when it comes to those spiral ramps in multistory parking garages. Stacked and connecting parallel levels, the ramps are replications of helical structures found in a ubiquitous membrane structure in the cells of the body.

A new method simplifies the analysis of RNA structure

Scientists have devised a simple and versatile method, based on the geometry of the RNA molecule, which proved to be highly promising for analysing and understanding the complex interactions that characterise these molecules.
