A study of seven tropical forests around the world has revealed that nature encourages biodiversity by favoring the growth of less common trees. The landmark study, conducted by 33 ecologists from 12 countries and published in the Jan. 27 issue of the journal Science, conclusively demonstrates that diversity matters and has ecological importance to tropical forests. Helene Muller-Landau, an assistant professor of ecology in the University of Minnesotas College of Biological Sciences, is a co-author of the study, which supports previous research by her colleague David Tilman, a Regents Professor of Ecology, into the causes and value of biodiversity.
"This research has the surprising finding that biodiversity in tropical rain forests and Minnesota prairies arises from the same kinds of underlying processes. It brings us a step closer to understanding the causes of the worlds amazing biodiversity," Tilman said.
Muller-Landau contributed quantitative skills for analyzing and interpreting the data.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
