University of Leicester researchers suggest a turning point for the planet and its resources
Human beings are pushing the planet in an entirely new direction with revolutionary implications for its life, a new study by researchers at the University of Leicester has suggested.
The research team led by Professor Mark Williams from the University of Leicester's Department of Geology has published their findings in a new paper entitled 'The Anthropocene Biosphere' in The Anthropocene Review.
Professor Jan Zalasiewicz from the University of Leicester's Department of Geology who was involved in the study explained the research: "We are used to seeing headlines daily about environmental crises: global warming, ocean acidification, pollution of all kinds, looming extinctions. These changes are advancing so rapidly, that the concept that we are living in a new geological period of time, the Anthropocene Epoch - proposed by the Nobel Prize-winning atmospheric chemist Paul Crutzen - is now in wide currency, with new and distinctive rock strata being formed that will persist far into the future.
"But what is really new about this chapter in Earth history, the one we're living through? Episodes of global warming, ocean acidification and mass extinction have all happened before, well before humans arrived on the planet. We wanted to see if there was something different about what is happening now."
The team examined what makes the Anthropocene special and different from previous crises in Earth's history. They identified four key changes:
In total, the team suggests that these changes represent a planetary transformation as fundamental as the one that saw the evolution of the photosynthetic microbes which oxygenated the planet 2.4 billion years ago, or that saw the transition from a microbial Earth to one dominated by multicellular organisms half a billion years ago.
Professor Williams added: "We think of major changes to the biosphere as the big extinction events, like that which finished off the dinosaurs at the end of the Cretaceous Period. But the changes happening to the biosphere today may be much more significant, and uniquely are driven by the actions of one species, humans."
The team includes Professor Mark Williams and Jan Zalasiewicz (University of Leicester), Peter Haff (Duke University, USA), Christian Schwägerl (Aßmannshauser Strasse 17, Berlin, Germany), Anthony D Barnosky (University of California, USA) and Erle C Ellis (University of Maryland, Baltimore County, USA).

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
