(University of Johannesburg) Fly ash generated by coal-fired power stations is a global environmental headache, creating groundwater and air pollution from vast landfills and ash dams. The waste product can be repurposed into geopolymer concrete, such as precast heat-cured structural elements for buildings. However, a critical durability problem has been low resistance to extreme alkali attack. UJ researchers found that high temperature heat-treatment at 200 degrees Celsius can halve this harmful mechanism in fly ash geopolymer concretes.

(Max Planck Institute for the Science of Human History) What makes our species unique compared to other hominins? High profile genetic, fossil and material culture discoveries present scientists working in the Late Pleistocene with an ever-more complex picture of interactions between early hominin populations. One distinctive characteristic of Homo sapiens, however, appears to be its global distribution. Exploring how Homo sapiens colonized most of the world's continents in a relatively short period could reveal the exceptional capacities of humans relative to other hominins.

(Max Planck Institute for the Science of Human History) Three 16th-century skeletons from a mass burial in Mexico City highlight the role of the transatlantic slave trade in introducing and disseminating new pathogens to the Americas. Researchers from the Max Planck Institute for the Science of Human History and Escuela Nacional de Antropología e Historia in Mexico analyzed skeletal features, genetic data and isotopes to explore the life history of three enslaved Africans and explore the wide-ranging impacts of massive forced migration.

(University of Chicago Press Journals) Extensive cooperation among biologically unrelated individuals is uniquely human. It would be surprising if this uniqueness were not related to other uniquely human characteristics, yet current theories of human cooperation tend to ignore the human aspects of human behavior. This paper presents a theory of cooperation that draws on social, cultural, and psychological aspects of human uniqueness for which current theories have little or no explanation.

(Universitat Pompeu Fabra - Barcelona) Expansions by groups of humans were common during prehistoric times, after the adoption of agriculture. Among other factors, this is due to population growth of farmers which was greater than of that hunter-gatherers. We can find one example of this during the Neolithic period, when farming was introduced to Europe by migrations from the Middle East.

(Perot Museum of Nature and Science) Published in PLOS ONE today, a study by an international team from the Perot Museum of Nature and Science in Dallas and Hokkaido University in Japan further explores the proliferation of the most commonly occurring duck-billed dinosaur of the ancient Arctic as the genus Edmontosaurus. The findings reinforce that the hadrosaurs -- dubbed 'caribou of the Cretaceous' -- had a geographical distribution of approximately 60 degrees of latitude, spanning the North American West from Alaska to Colorado.

Although the ill effects of these chemical reactions can be curtailed by antioxidants, creating a sturdy platform capable of providing prolonged antioxidant activity is an ongoing challenge.

(Purdue University) Researchers at Purdue University have discovered that male treefrogs reduce their attractiveness to predators and parasites by overlapping their mating calls with their neighbors.

(Arizona State University) Hydrogen is an essential commodity with over 60 million tons produced globally every year. However over 95 percent of it is made by steam reformation of fossil fuels, a process that is energy intensive and produces carbon dioxide. If we could replace even a part of that with algal biohydrogen that is made via light and water, it would have a substantial impact.

(University of Bonn) The extent to which Brazilian soy production and trade contribute to climate change depends largely on the location where soybeans are grown. This is shown by a recent study conducted by the University of Bonn together with partners from Spain, Belgium and Sweden. In some municipalities, CO2 emissions resulting from the export of soybean and derivatives are more than 200 times higher than in others.
