Researchers from Japan and Indonesia have pioneered a new method for more accurately estimating the source of weak ground vibrations in areas where one tectonic plate is sliding under another in the sea. Applying the approach to Japan s Nankai Trough, the researchers were able to estimate previously unknown properties in the region, demonstrating the method s promise to help probe properties needed for better monitoring and understanding larger earthquakes along this and other plate interfaces.
An international research team led by chemist Prof. Thomas Heine of TU Dresden has discovered a new two-dimensional material with unprecedented properties: regardless if it is strained or compressed, it always expands. This so-called half-auxetic behavior has not been observed before and is therefore very promising for the design of new applications, especially in nano-sensorics.

Tiny photonic devices could be used to find new exoplanets, monitor our health, and make the internet more energy efficient. Researchers from Chalmers University of Technology, Sweden, now present a game changing microcomb that could bring advanced applications closer to reality.
A microcomb is a photonic device capable of generating a myriad of optical frequencies - colours - on a tiny cavity known as microresonator. These colours are uniformly distributed so the microcomb behaves like a ruler made of light . The device can be used to measure or generate frequencies with extreme precision.

Japanese researchers have developed a simulation method to theoretically estimate the performance of heterogeneous catalyst by combining first-principles calculation (1) and kinetic calculation techniques. Up to now, simulation studies mainly focused on a single or limited number of reaction pathways, and it was difficult to estimate the efficiency of a catalytic reaction without experimental information.
Atsushi Ishikawa, Senior Researcher, Center for Green Research on Energy and Environmental Materials, National Institute for Materials Science (NIMS), performed computation of reaction kinetic information from first-principles calculations based on quantum mechanics, and developed methods and programs to carry out kinetic simulations without using exp

A team of scientists from the University of Cologne (Germany) and the University of Uppsala (Sweden) has created a model that can describe and predict the evolution of antibiotic resistance in bacteria. Resistance to antibiotics evolves through a variety of mechanisms. A central and still unresolved question is how resistance evolution affects cell growth at different drug concentrations. The new model predicts growth rates and resistance levels of common resistant bacterial mutants at different drug doses. These predictions are confirmed by empirical growth inhibition curves and genomic data from Escherichia coli populations. The study has been published in the journal
