(Lancaster University) An international team of researchers has discovered a new material made from manganese hydride that would be used to make molecular sieves within fuel tanks - which store the hydrogen and work alongside fuel cells in a hydrogen powered 'system'.The material would enable the design of tanks that are far smaller, cheaper, more convenient and energy dense than existing hydrogen fuel technologies, and significantly out-perform battery-powered vehicles.

(Arizona State University, Center for Global Discovery and Conservation Science) According to a new study published today in the journal Proceedings of the National Academy of Sciences, airborne surveys show that, on a large scale, the spatial arrangement of savanna trees follows distinct patterns that can be described mathematically regardless of variation in environmental factors.

(University of Plymouth) The way humans use land across the British Isles has changed beyond recognition during the past 8,000 years. But what impact has that had on biodiversity and are there lessons from the past that could enhance conservation practices now and in the future?

(Skolkovo Institute of Science and Technology (Skoltech)) The collaborative effort of researchers from Skoltech, SB RAS Nikolaev Institute of Inorganic Chemistry, and RAS Institute for Problems of Chemical Physics translated into the development of advanced lead-free semiconductors for solar cells, based on complex antimony and bismuth halides. The results of their study were published in the Journal of Materials Chemistry A and showcased on the journal's cover page.
