Humans are not alone in creating ‘signposts’ to help them find their way, according to new research published in the open access journal BMC Ecology. Wood mice, say scientists, move objects from their environment around using them as portable signposts whilst they explore.
The finding is significant as this is the first time such sophisticated behaviour has been identified in any mammal except humans. According to the authors,
“This is precisely how a human might tackle the problem of searching efficiently in a homogeneous environment – for example by placing a cane in the ground as a reference point from which to search for a set of keys dropped on a lawn.”

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
