South American marsupials discovered to reach new heights

There have long been speculations that the mouse-sized marsupial monito del monte climbs to lofty heights in the trees. Yet, no previous records exist documenting such arboreal habits for this creature. Researchers set motion-sensing camera traps to capture photographic evidence confirming the high-climbing theories surrounding this miniature mammal. from Latest Science News -- ScienceDaily https://ift.tt/2ysOEN3

Working lands play a key role in protecting biodiversity

Diversifying working lands -- including farmland, rangeland and forests -- may be key to preserving biodiversity in the face of climate change, says a new review article. These changes could extend the habitat of critters like bats, but also much larger creatures like bears, elk and other wildlife, outside the boundaries of protected areas, while creating more sustainable, and potentially more productive, working lands. from Latest Science News -- ScienceDaily https://ift.tt/2NSVaBO

Genetic breakthrough will aid whitebark pine conservation efforts

Neo-colonial attitudes to security in war-torn nations out-of-date and unhelpful

Developed countries imposing their own Security Sector Reform (SSR) processes onto nations recovering from war often rely on entrenched colonial attitudes with no guarantee of success. Researchers looked at the Democratic Republic Congo and Nepal contrasting their outcomes and examining the reasons for success or failure of SSR policies based on Europe.

Extremely small magnetic nanostructures with invisibility cloak imaged

In novel concepts of magnetic data storage, it is intended to send small magnetic bits back and forth in a chip structure, store them densely packed and read them out later. The magnetic stray field generates problems when trying to generate particularly tiny bits. Now, researchers were able to put an 'invisibility cloak' over the magnetic structures. In this fashion, the magnetic stray field can be reduced in a fashion allowing for small yet mobile bits. from Latest Science News -- ScienceDaily https://ift.tt/2ystj6p
