NOAA Fisheries Service published with the Federal Register today a proposed rule to list black abalone, a marine mollusk coveted by fishermen and gourmets alike, as endangered under the Endangered Species Act (ESA). The proposal comes after NOAA Fisheries Service considered the report of a scientific review team concluding that the species is at risk of extinction.
“The scientific review team reported major declines in the population of black abalone, especially in the areas around the Channel Islands off Southern California,” said Rod McInnis, Southwest Regional Administrator for NOAA’s National Marine Fisheries Service. “These proposed regulations seek federal protection for black abalone and request input from the public in determining what areas might be included as critical habitat for the species.”
Black abalone were once plentiful in the intertidal waters from Northern Baja California, Mexico, to Monterey, Calif., although there is some scientific debate about how far north the population once extended. The species was utilized by early California natives and peaked as a commercial fishery in the state in 1973 with almost two million pounds harvested.
Since the 1980s, black abalone abundance has plummeted primarily from a bacterial disease known as withering syndrome. Other causes of the rapid population decline are likely due to historical overfishing, poaching and natural predation. NMFS has considered recent preliminary evidence which suggests a small disease resistant population may exist at San Nicolas Island. Even with this possibility, the likelihood that black abalone populations will continue to decline towards extinction (within the next 30 years) is very high.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
