A paper in this weeks journal Nature, building on radically new ecological theory by University of Georgia professor Stephen Hubbell, challenges half-century-old ideas about how natural plant and animal communities are put together.
The paper in Nature includes research by physicists Jayanth Banavar and Igor Volkov of Penn State University and Amos Maritan of the International School for Advanced Studies in Trieste, Italy, along with Hubbell.
Conventional ecological theory says that species coexist with one another by being different and the best competitors in their own ecological niches (functional roles) in the community. Hubbell challenged this theory in a widely acclaimed but controversial 2001 book called "The Unified Neutral Theory of Biodiversity and Biogeography." In it he argued that many of the ecological patterns we see can be more simply and often better explained if competing species are treated as if they were essentially identical.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
