Published Giant fossil seeds from Borneo record ancient plant migration
(via sciencedaily.com) Original source Ancient fossil beans about the size of modern limes, and among the largest seeds in the fossil record, may provide new insight into the evolution of today's diverse Southeast Asian and Australian rainforests, according to researchers who identified the plants.
Published Halogen bonding for selective electrochemical separation, path to sustainable chemical processing demonstrated
(via sciencedaily.com) Original source A team has reported the first demonstration of selective electrochemical separation driven by halogen bonding. This was achieved by engineering a polymer that modulates the charge density on a halogen atom when electricity is applied. The polymer then attracts only certain targets -- such as halides, oxyanions, and even organic molecules -- from organic solutions, a feature that has important implications for pharmaceuticals and chemical synthesis processes.
Published Engineers bring efficient optical neural networks into focus
(via sciencedaily.com) Original source Researchers have published a programmable framework that overcomes a key computational bottleneck of optics-based artificial intelligence systems. In a series of image classification experiments, they used scattered light from a low-power laser to perform accurate, scalable computations using a fraction of the energy of electronics.
Published Millions of years for plants to recover from global warming
(via sciencedaily.com) Original source Catastrophic volcanic eruptions that warmed the planet millions of years ago shed new light on how plants evolve and regulate climate. Researchers reveal the long-term effects of disturbed natural ecosystems on climate in geological history and its implications for today.
Published Increasing solid-state electrolyte conductivity and stability using helical structure
(via sciencedaily.com) Original source Solid-state electrolytes have been explored for decades for use in energy storage systems and in the pursuit of solid-state batteries. These materials are safer alternatives to the traditional liquid electrolyte -- a solution that allows ions to move within the cell -- used in batteries today. However, new concepts are needed to push the performance of current solid polymer electrolytes to be viable for next generation materials.
Published Nature at risk in the hunt for the perfect selfie
(via sciencedaily.com) Original source The need for a dramatic selfie or the perfect landscape photo is proving detrimental to nature, a new research collaboration has found.
Published Electric bandage holds promise for treating chronic wounds
(via sciencedaily.com) Original source Researchers have developed an inexpensive bandage that uses an electric field to promote healing in chronic wounds. In animal testing, wounds that were treated with these electric bandages healed 30% faster than wounds treated with conventional bandages.
Published Turning unused signals such as Wi-Fi into energy for electronics

Published New report on Great Barrier Reef shows coral cover increases before onset of serious bleaching, cyclones
(via sciencedaily.com) Original source Coral cover has increased in all three regions on the Great Barrier Reef and is at regional highs in two of the three regions, according to a new report. But the results come with a note of caution.
Published Stacking molecules like plates improves organic solar device performance
(via sciencedaily.com) Original source Researchers found that how well light-converting molecules stack together in a solid is important for how well they convert light into electric current. A rigid molecule that stacked well showed excellent electricity generation in an organic solar cell and photocatalyst, easily outperforming a similar flexible molecule that did not stack well. This new way of improving the design of molecules could be used to pioneer the next generation of light-converting devices.
