"We found that if you have the key spatial (location) information on fish, you can put the Marine Protected Areas in the right places, thus increasing conservation and making the fisheries more profitable," said Christopher Costello, economist and professor with UC Santa Barbara's Bren School of Environmental Science & Management.
Information on fish, from spawning habits to oceanographic models that show currents, gives the experts the data needed for both conservation and increased fishing, according to Costello, who published an article on the topic this week in the Proceedings of the National Academy of Sciences.
"You can have conservation and increased fisheries at the same time," he said. "That will be surprising to a lot of people. We tend to think that it's either the economy or the environment and that you can't have both. This is a case where you can have both, but you need that spatial information in order to achieve it."
Costello has served on two recent Science Advisory Teams for the development of California's Marine Protected Areas (MPAs), and is now on a third team, for the design of MPAs in Northern California. The state is in the process of developing MPAs from Point Conception south to the Mexican border. Northern MPAs will be next.
He explained that he and his team of co-authors studied the location of fish by looking at what ecologists call "sources" and "sinks." In source areas, the ocean is very productive and lots of fish spawn there. Larvae are produced and they are swept over to the sink and never leave.
"What you'd really like to do is close the source to fishing and only fish in the sink," said Costello. "It turns out you get a much higher economic value and much better conservation when you do that. But if you don't know where the sources and sinks are, you can't do that, so that is where the information comes in."
He explained that in Southern California the experts have that information and are using it to set up the new MPAs. "However, in many parts of the world, we don't yet have the information," said Costello. "Until this article came out, there was a vague idea that yes, we want better information –– but it wasn't clear why or how we would use it."
The article asserts, "spatial information has the potential to change management approaches."

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.
