Surface tessellations are an arrangement of shapes which are tightly fitted, and form repeat patterns on a surface without overlapping. Imagine the pattern of a giraffe's fur, the shell of a tortoise and the honeycomb of bees -- all form natural tessellations. A global team of computer scientists has developed a new, alternate model for replicating these intricate surface designs, veering away from classical, multi-step approaches to a more efficient, streamlined algorithm.
An indicator to measure plant conservation shows a wide range of wild plants used for food, medicine, shelter, fuel, livestock forage and other valuable purposes are at risk. These include wild populations of firs used for Christmas trees, the original types of kitchen-cupboard staples like vanilla, chamomile, cacao and cinnamon, wild relatives of crops like coffee, and non-cultivated plants used by bees to make honey.
Army scientists have found a novel way to safeguard quantum information during transmission. This finding has the potential to lead to more secure and reliable communication for warfighters on the battlefield.
Economic conditions can shape the decisions that adults make about their families, such as whether and when to have children. A recent Journal of Marriage & Family analysis of US women aged 20 to 44 years found that higher unemployment rates were associated with a lower likelihood of unintended pregnancy.
In recent years, cities have asserted themselves as relevant actors in efforts to address global climate change. The announcement by the United States of their intent to withdraw from the Paris Agreement has generated more attention than ever for what cities and other subnational authorities can do in this field.
Chile is currently undergoing a renewable energy boom. Today, it's the second largest market for renewable energies in Latin America, and in 2016 Chile was the top-scoring renewable energy producer in the Americas and second in the world, beaten only by China. Two decades ago, when this process started, this transformation was unthinkable.
Total US investment in medical and health research and development (R&D) in the US grew by 27 percent over the five-year period from 2013 to 2017, led by industry and the federal government, according to US Investments in Medical and Health Research and Development, a new report from Research!America. Industry accounted for 67 percent of total spending in 2017, followed by the federal government at 22 percent.
Computer scientists from the Georgia Institute of Technology and Google Brain, Google's artificial intelligence research arm, have devised a novel computational method, driven by machine learning techniques, to successfully and realistically simulate the multi-step process of putting on clothes. The new method will be presented at SIGGRAPH Asia 2018
New research by the Work Foundation finds that while businesses increasingly recognize employee benefits as vital in the global race for talent, many are failing to maximize their value for low earners amongst their workforce.
Changes to the media environment have increased polarized voting in America through both addition and subtraction. We argue that the decline of local newspapers has contributed to the nationalization of American politics: as local newspapers close, Americans rely more heavily on available national news or partisan heuristics to make political decisions.
