Researchers from Lanzhou University in China have shown that the slime mold Physarum polycephalum is able to solve the Traveling Salesman Problem, a combinatorial test with exponentially increasing complexity, in linear time. Using focused light stimulus as negative feedback to maintain the criteria of the task, the authors demonstrated that this model was able to reliably output a high-quality solution. — Sci-News.com
Through observing physarum polycephalum, nicknamed the "many-headed slime", researchers have used its natural network formation to help solve many spatial design problems. Slime mold has shown itself capable of recreating rail systems, solving mazes, and now, the Traveling Salesman Problem—a... View full entry

In the 18 months or so since dockless bike-share arrived in the US, the service has spread to at least 88 American cities. (On the provider side, at least 10 companies have jumped into the business; Lime is one of the largest.) Some of those cities now have more than a year of data related to the programs, and they’ve started gleaning insights and catering to the increased number of cyclists on their streets. — MIT Technology Review
Technology Review writer Elizabeth Woyke looks at ways how city planners in Seattle, WA and South Bend, IN use the immense stream of user-generated location data from dockless-bike-sharing programs to improve urban mobility — and how hackers could potentially access and abuse this (supposedly...
