Research cruise provides new information on tsunami during survey of remote area
A summer voyage to investigate the causes of one of the most devastating tsunamis in United States history has uncovered new mysteries about biological and geological processes off Alaska. Probing the depths below one of the worlds most important fisheries, scientists with Scripps Institution of Oceanography at the University of California, San Diego, as well as Indiana State University and their colleagues, conducted the first exploration of deep seafloor biological communities in a sector of the Alaskan margin off the Aleutian Islands along the northern part of the Pacific Rim.
In addition to identifying previously undiscovered deep-sea habitats, the researchers have stirred debate about the causes and characteristics of a devastating 1946 tsunami. The Pacific Ocean-wide event led to more than 150 deaths and widespread destruction as it pounded shorelines from Alaska to Antarctica. The July research cruise, aboard the Scripps research vessel Roger Revelle, was sponsored by the National Oceanic and Atmospheric Administrations West Coast National Undersea Research Program.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
