Galton analyzed hundreds of estimates and found that while individual guesses varied wildly, the median of the entries was surprisingly accurate and within one percent of the ox's real weight. When Galton published his results, he ushered the theory of collective intelligence, or the "wisdom of crowds," into the public conscience.

Mathematics Tue, 02 Jan 2018 12:50:29 EDTnews434119821Statistical test relates pathogen mutation to infectious disease progressionNucleic acid sequencing methods, which determine the order of nucleotides in DNA fragments, are rapidly progressing. These processes yield large quantities of sequence data—some of which is dynamic—that helps researchers understand how and why organisms function like they do. Sequencing also benefits epidemiological studies, such as the identification, diagnosis, and treatment of genetic and/or contagious diseases. Advanced sequencing technologies reveal valuable information about the time evolution of pathogen sequences. Because researchers can estimate how a mutation behaves under the pressure of natural selection, they are thus able to predict the impact of each mutation—in terms of survival and propagation—on the fitness of the pathogen in question. These predictions lend insight to infectious disease epistemology, pathogen evolution, and population dynamics.

When carrying a liquid, common sense says to walk slowly and refrain from overfilling the container. But when commuters rush out the door with coffee in hand, chances are their hastiness causes some of the hot liquid to slosh out of the cup. The resulting spills, messes, and mild burns undoubtedly counteract coffee's savory benefits.

The model can replicate patterns of melanoma cell growth seen in laboratory experiments by controlling the 'exclusion area'—the amount of space required—around two types of simulated cells as they grow and spread. A paper describing the model and experiments appears in a recent issue of the journal Scientific Reports.
