Consumers' credit cards are declined surprisingly often in legitimate transactions. One cause is that fraud-detecting technologies used by a consumer's bank have incorrectly flagged the sale as suspicious. Now MIT researchers have employed a new machine-learning technique to drastically reduce these false positives, saving banks money and easing customer frustration.
There's quite a story behind calaverite. Apart from its marked impact on the Gold Rush, the mineral has been a headache and a great paradox for crystallographers for decades. The deeper researchers dug into it, the more new questions came up. Scientists from Russia and Germany have succeeded in interlacing all the oddities of calaverite within a simple model, so experimenters can now hunt for the new compound they predicted, AuTe, unknown until now.
There are currently millions of heavily underutilized devices in the World. The storage, networking, sensing and computational power of laptops, smartphones, routers or base stations grows with each new version and product release. Why not put all those extra gigabytes of memory and those powerful processing units to work collaboratively and expand the services available to all of us?
"We used our data-driven tools to derive significant insight into how the process works that allows us to design the correct additives to get the desired outcomes," Sigman said. The results allow chemists to control which stereochemical product comes out of the reaction, simply by selecting the right ligand. It's more than just a laboratory convenience, though. The study also reveals much more about how this important chemical process works.
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.
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.
