Marine seismology reveals Hawaiian volcano’s past, sheds light on future dangers
The Hawaiian Islands are home to the largest documented shoreline collapse in history, an ancient seaward landslide that sent rocks from the island of Oahu to sites more than 100 miles offshore. The avalanche of debris from the northeast shore of Oahu probably occurred between 1.5 and 3 million years ago, and it undoubtedly created one of the largest tsunamis in Earths history, a wave large enough to inundate every coastline of the northern Pacific Ocean.
Today, geologists are studying whether seismic and tectonic forces are creating the potential for a similar disaster on the southeast shore of the big island of Hawaii, near Kilauea volcano. The worlds most active volcano, Kilauea is continually growing larger. At the same time, its seaward flank is moving toward the Pacific, currently at the rate of about 10 centimeters per year. Kilaueas movement takes several forms. Layers of lava and sediment atop the mountain are pulled down by the force of gravity. The entire mountain itself also moves slowly out to sea as magma derived from deep within the earths mantle intrudes into the core of the volcano.

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.
