For the first time, scientists have simulated the seismic signals that precede a volcanic eruption and created a 3-D visualization of those warning signs under controlled conditions. By performing tests on basalt rock from Sicily’s still-active volcano Mt. Etna, the team was able to record the seismic waves generated during the earthquakes that occur before volcanic eruptions.
"Nearly 500 million people live close enough to the planet’s 600 currently active volcanoes that they face serious harm, both physically and economically, should a major eruption occur. Being able to simulate the pressure conditions and events in volcanoes will greatly assist geophysicists in exploring the scientific basis for volcanic unrest. We cannot predict eruptions with total accuracy, but understanding these pre-eruption events better will help cities and towns near volcanoes know better whether they need to take the precaution of having people evacuate the area or not,” said Dr. Paul Young, Keck Chair of Seismology and Rock Mechanics as well as U of T’s Vice-President, Research.
Dr. Young noted that the information gathered through this investigation should also prove useful to other industries including mining and construction as well as to scientists studying other earth sciences phenomena
The international team of scientists involved in these ground-breaking experiments was Visiting Lassonde Institute Research Fellow, Dr. Philip Benson, who is also the Marie- Curie Research Fellow in Earth Sciences at University College London; Dr. Philip Meredith of the Rock and Ice Physics Laboratory, also from University College London; Dr.Sergio Vinciguerra of Rome’s National Geophysics and Volcano Institute; and Dr. Young. Their findings are published in a recent edition of the journal Science.For further information, please contact:

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.
