A reconstruction of land movements and changes in sea levels for three massive historic earthquakes in Alaska gives clues that may help scientists forecast future earthquakes and earthquake-triggered tsunami. To be published in this week’s Journal of Quaternary Science¹ the findings should help reduce losses from future catastrophic events.
Investigators Sarah Hamilton and Ian Shennan from the University of Durham, England, studied three earthquakes that occurred around 1400-1500 years ago, about 950-850 years ago, and in 1964 at Kenai, southern Alaska.
They found a pattern of change associated with each earthquake. Land in the area was generally rising, but subsided in the years immediately before each great earthquake. Such pre-seismic land subsidence may be one of the indicators that lead up to a great plate-boundary earthquake. Their data show that while earthquake-induced land subsidence was associated with each earthquake, the exact pattern of this subsidence varied during the different events.

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.
