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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
