Many ways to approach the Riemann Hypothesis have been proposed during the past 150 years, but none of them have led to conquering the most famous open problem in mathematics. A new paper in the Proceedings of the National Academy of Sciences (PNAS) suggests that one of these old approaches is more practical than previously realized.
Virtual Reality takes over ever more areas of our lives so it is important that virtual worlds offer high usability. Until now, the only way to check was to conduct tests with volunteers -- time-consuming and cost-intensive. Dr Patrick Harms from the Institute of Computer Science at the University of Göttingen developed technology that automatically detects many problems with user-friendliness and usability in the virtual environment. The results appeared in 'ACM Transactions on Computer-Human Interaction'.
Researchers have identified how the human brain is able to determine the properties of a particular object using purely statistical information: a result which suggests there is an 'inner pickpocket' in all of us.
A new study in Journal of Applied Ecology equips scientists to more accurately predict whether, and when, a species will go extinct by being more realistic about how long it takes populations to establish each new generation.
Researchers have developed a new framework for deep neural networks that allows artificial intelligence (AI) systems to better learn new tasks while 'forgetting' less of what it has learned regarding previous tasks. The researchers have also demonstrated that using the framework to learn a new task can make the AI better at performing previous tasks, a phenomenon called backward transfer.
Reproducible scientific results are not always true and true scientific results are not always reproducible, according to a mathematical model produced by University of Idaho researchers.
SUTD researchers have developed a novel approach to untangle the centralization phenomena in blockchain mining by employing the rich economic theory of Oceanic Games. The application of this theory in the blockchain ecosystem unveiled incentives for both active and newly entering miners to merge and act as single entities and provides an alternative justification of the centralization and concentration of power in the mining process of major cryptocurrencies.
A new type of money that allows users to make decisions based on information arriving at different locations and times, and that could also protect against attacks from quantum computers, has been proposed by a researcher at the University of Cambridge.
As the data boom continues to boom, more and more information gets filed in less and less space. Even the cloud will eventually run out of space, can't thwart all hackers, and gobbles up energy. Now, a new way to store information could stably house data for millions of years, lives outside the hackable internet, and, once written, uses no energy. All you need is a chemist, some cheap molecules, and your precious information.
To better understand whether rapidly growing cities are hosting the same species, a team from the California Academy of Sciences analyzed an immense volume of data gathered by citizen scientists during the four-day global City Nature Challenge. Study findings suggest that despite similarities across cities, urban biodiversity still strongly reflects the species that are native to a region. However, observations of shared 'cosmopolitan' species like pigeons, white-tailed deer, and dandelions were more numerous than locally occurring species.
