An extensive study on the Indo-Pacific coral reefs, about to be published in the 2nd of March issue of the journal Nature challenges the present conservation protocols for these organism and calls for important changes in the way that protected areas are being established all over the world, in order to be able to stop the present (fast) rate of extinction observed in coral reefs.
A major ongoing discussion in ecology is what determines the biodiversity (which species and in what abundance) of a community. To the Darwinian theory of natural selection, in order to co-habit, different species have to occupy different living environments (also called ecological niches). Because, if they compete, for example, for space or food, inevitably only one of the species will survive – this is known as the “survival of the fittest”. However, some ecosystems, like coral reefs, have such an incredibly large biological diversity that is difficult to be explained by the “niche” model.
The Neutral Theory of Biodiversity is a controversial and exciting new ecological model that tries to explain how these high diversity ecosystems can occur, and which claims that co-habitation of different species in a particular environment is simply the result of a random migration into the same habitable region. According to this model, differences between similar groups of species living in an ecological community can be considered "neutral" or irrelevant to their success. This means that, if for example one species of bird seems to be better suited to a particular environment, this should not increase its odds to survive in that environment in comparison to another bird species. In this way, biodiversity results solely from random fluctuations in processes such as migration, birth rate, death, etc.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
