Engineers at MIT have devised a framework for identifying key patterns that precede an extreme event. The framework can be applied to a wide range of complicated, multidimensional systems to pick out the warning signs that are most likely to occur in the real world.
Nature Communications today published research by a team comprising Scottish and South African researchers, demonstrating entanglement swapping and teleportation of orbital angular momentum 'patterns' of light. This is a crucial step towards realizing a quantum repeater for high-dimensional entangled states.
When a fluid or a gas experiences a sudden disturbance, it often gives rise to a phenomenon known as an undular bore, which consists of a series of rapid oscillations that propagate and spread. But how to describe what transpires? New mathematics research brings us closer to finding an answer.
UZH researchers have taught drones how to fly using an eye-inspired camera, opening the door to them performing fast, agile maneuvers and flying in low-light environments. Pos-sible applications could include supporting rescue teams with search missions at dusk or dawn.
How do multilingual people solve arithmetical tasks presented to them in different languages? The question will gain in importance in the future, as an increasingly globalized job market and accelerated migration will mean that ever more people seek work and study outside of the linguistic area of their home countries. This question was investigated by a research team led by Dr Amandine Van Rinsveld and Professor Dr Christine Schiltz from the Cognitive Science and Assessment Institute (COSA) at the University of Luxembourg.
A pioneering method, developed at Chalmers University of Technology, has demonstrated its potential in a large study, showing that metabolic fingerprints from blood samples could render important new knowledge on the connection between food and health. The study finds that diet is one of the strongest predictors of type 2 diabetes risk in older women.
The era of fully fledged quantum computers threatens to destroy internet security as we know it. Researchers are in a race against time to prepare new cryptographic techniques before the arrival of quantum computers, as cryptographers Tanja Lange (Eindhoven University of Technology, the Netherlands) and Daniel J. Bernstein (University of Illinois at Chicago, USA) describe today in the journal Nature. In their publication they analyze the options available for this so-called post-quantum cryptography.
Scientists compared the data on the coordinates of quasars obtained by Gaia and VLBI and suggested a method for revealing structure indirectly by means of combining the data from existing telescopes. Moreover, the precision they've got is superior to what is possible with ordinary optical telescopes and even with Hubble.
Programmers from ITMO University created a computer algorithm that allows tourists to find places of interest that are most popular with locals based on their instagram posts. To test the algorithm, the team analyzed Instagram photos taken in Saint Petersburg and compiled a list of museums, cafes, streets, and event venues preferred by the residents of Russia's northern capital, thus providing local suggestions to tourists.
Researchers at the Helmholtz Zentrum München have developed a new method for reconstructing continuous biological processes, such as disease progression, using image data. The study was published in 'Nature Communications'.
