A team of 27 U.S. marine scientists beginning an intensive program of exploration at the Lau Basin in the South Pacific has discovered a new cluster of hydrothermal vents along a volcanically active crack in the seafloor. About a mile and a half down, the basin could hold answers to questions about the origin of life on Earth, say the scientists, whose plans for their "South Pacific Odyssey" include an unprecedented number of research expeditions to this geologically unique "back-arc basin" during the next two years.
"This major undertaking will require the coordinated efforts of dozens of large research groups, numerous research expeditions, and the deployment of a wide array of specialized deep-sea research tools," said Penn State Professor of Biology Chuck Fisher, chair of the NSF-funded Ridge 2000 research initiative, which is behind this effort. “Because of the unusual properties of the ocean crust in the Lau Basin, we can expect to discover new species there--species that perhaps will hold new and unique secrets to share with us," Fisher said. "The microbes at sites like these--thriving in super-hot temperatures--likely have their own remarkable biochemical pathways and capabilities that we are only beginning to appreciate."
"The Lau Basin is a candy store of scientific problems, and this is the first time there’s been a regional-scale perspective of hydrothermal activity in an entire back-arc basin," said Charlie Langmuir of Harvard University, a marine geologist who is the chief scientist of the current cruise and a veteran of over 20 deep-sea expeditions in the last two decades. "If we’re successful, it will also be the first time that a systematic exploration and discovery of hydrothermal vents over hundreds of kilometers has been achieved."

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.
