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.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
