Diverse landscapes are more productive and adapt better to climate change
Ecosystems with high biodiversity are more productive and stable towards annual fluctuations in environmental conditions than those with a low diversity of species.

Approach enables experts to look beyond IP in cyber security investigations
A technique which enables digital forensic investigators to assess an individual's internet use rather than simply focusing on traffic through Internet Protocol (IP) addresses has been developed by cyber security experts at the University of Plymouth and is outlined in a study published in the September 2017 issue of Computers & Security.

The figure rises to one in four during the dark winters in Ireland, while the research also points to rising age, smoking, living alone, and living in a lower socioeconomic background as factors associated with deficiency.

Humans learn complex grammatical patterns even in extremely challenging circumstances
A large-scale study of languages shows that the grammar of creoles -- which emerged in multilingual situations of extreme social upheaval, like colonial slaveries -- are composed from the grammars of other languages that preceded them rather than being innovated from scratch.
