New insight into mammalian stem cell evolution

The genes regulating pluripotent stem cells in mammals are surprisingly similar across 48 species, Kyoto University researchers report in the journal Genome Biology and Evolution. The study also shows that differences among ...

Evolutionary conflicts predicted

Evolution seems to be an unpredictable process. However, predicting the constraints of evolution is possible. Researchers from AMOLF and the French ESPCI have demonstrated this using their mathematical method, followed by ...

Making systems robust

The human body keeps the calcium concentration in the blood constant, similarly to an aircraft's autopilot keeping the plane at a constant altitude. What they have in common is that both the body and the autopilot employ ...

Can you evolve while being robust?

It was long thought that DNA, together with the genes encoded in it, determined genetic destiny. But equally important is coordinating when genes are turned on and off. In fact, the regulation of gene expression defines life ...

The origin of flower-making genes

Flowering plants have evolved from plants without flowers. It is known that the function of several genes, called MADS-box genes, creates shapes peculiar to flowers such as stamens, pistils and petals. Plants that do not ...

Using networks to understand tissue-specific gene regulation

Researchers at Brigham and Women's Hospital have discerned that different tissue functions arise from a core biological machinery that is largely shared across tissues, rather than from their own individual regulators. In ...
