Yeast models of cell death and survival mechanisms

European scientists investigated differences in the genomes of various distantly-related yeast and their effects on cell survival. Results may provide insight into cell death induced by free radicals.

Reproductive isolation driving evolution of species

Evolution of species remains a hot topic since Darwin’s theory of natural selection. A European initiative addressed the issue of speciation from the viewpoint of reproductive isolation.

Salamanders spell out evolution in action

Lungless salamanders (Ensatina eschscholtzii) live in a horseshoe-shape region in California (a 'ring') which circles around the central valley. The species is an example of evolution in action because, while neighboring ...

Getting a step ahead of pathogens

A recent article in the journal Chaos examines the possibility of using epistasis to predict the outcome of the evolutionary processes, especially when the evolving units are pathogens such as viruses.

Genetic mismatch keeps yeast species distinct

How species form and what keeps them distinct from each other, even though they can interbreed, is a key question in evolution. Researchers from Taiwan, led by Dr. Jun-Yi Leu, an Assistant Research Fellow from the Institute ...

Little E/Z changes make a big difference

The coming of summer brings promise for humans and insects alike. The farmer planted maize for a bountiful harvest, but the European Corn Borer (ECB) is looking for a good meal right away. The caterpillars of this pest bore ...

How important is geographical isolation in speciation?

A genetic study of island lizards shows that even those that have been geographically isolated for many millions of years have not evolved into separate species as predicted by conventional evolutionary theory. Professor ...
