Provides new look at conservation of threatened coral species
An international research team has identified a family of corals found only in the Atlantic Ocean-a first for such classifications in that ocean-in a study that could transform how corals are viewed and classified. The scientists, who will publish their results in the Feb. 26 issue of the journal Nature, say the findings are also important for future decisions about coral conservation and the preservation of threatened biodiversity regions.
Led by Nancy Knowlton of the Scripps Institution of Oceanography of the University of California, San Diego, the study revealed significant flaws in the widely accepted taxonomy of Pacific and Atlantic corals. The team, which included researchers from the Smithsonian Tropical Research Institute in Panama, used DNA analysis to uncover a significant and previously undetected divergence between Pacific and Atlantic corals. Unexpectedly, the researchers found that about one-third of Atlantic corals, which had been conventionally classified in two distinct families found around the tropics, are in fact very closely related. But, the report says, the Atlantic corals are very different from Pacific corals assumed to be their close relatives. The two corals are so distinct, the scientists suggest the Atlantic variety constitutes its own family, making them the first such grouping unique to the Atlantic Ocean.

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...
