Your brain is structured to make the best possible decision given its limited resources, according to new research that unites cognitive science and information theory -- the branch of mathematics that underlies modern communications technology.
Newly identified bridge forms could enable significantly longer bridge spans to be achieved in the future, potentially making a crossing over the Strait of Gibraltar, from the Iberian Peninsula to Morocco, feasible. The new bridge forms -- identified by a team of researchers from the University of Sheffield and Brunel University London, working with long span bridge expert Ian Firth of engineering consultants COWI -- use a new mathematical modelling technique to identify optimal forms for very long-span bridges.
CNRS and EHESS researchers analyzed nearly 60 million political tweets posted during the 2017 presidential election in France. They noted that fake news flagged by the Le Monde Decodex fact-checking website accounted for only 0.1 percent of all Twitter content, and that 73 percent of the bogus information was spread by two political communities. Their findings are published in PLOS ONE.
Quantitative tools developed in math and physics to understand bifurcations in dynamical systems could help ecologists and biologists better understand -- and predict -- tipping points in animal societies.
MIT computer scientists have developed a system that learns to identify objects within an image, based on a spoken description of the image. Given an image and an audio caption, the model will highlight in real-time the relevant regions of the image being described.
A mobile app that guides pedestrians along the safest instead of quickest route to their destination is being developed by researchers at Cardiff University.
Historical bias is a key reason biomedical researchers continue to study the same 10 percent of all human genes whose sequences are known while ignoring many genes known to play roles in disease, according to a Northwestern University study. The bias is bolstered by research funding mechanisms and social forces. Well-meaning policy interventions to promote exploratory research result primarily in additional work on genes first characterized in the 1980s and 1990s, before completion of the Human Genome Project.
A new study suggests that defenses against extreme temperatures give E. coli bacteria an advantage in fending off certain drugs. The work could help doctors administer antibiotics in a more precise way.
RUDN University mathematicians simulated the work of a cellular network. In their model unmanned aerial vehicles are employed as additional transmitters. Most of the available communication systems give a flat coverage and do not take into account the difference in altitude, which results in the appearance of the so-called 'blind' zones. Flying drones will help in solving this issue. The work is published in the journal IEEE Transactions on Vehicular Technology.
Surf's up for microbes swimming beside red blood cells. New calculations and experiments model for the first time how spherical particles submerged in gooey liquid travel along a flexible rubber sheet; comparable conditions are common in the human body, such as blood cells flowing through a capillary or the journeys of self-propelled microbes. All these particles, it turns out, catch a wave.
