The colossal kauri trees prevent landslides on landslide-prone slopes. This is the conclusion of Dutch-funded researcher Lieven Claessens, who developed a model for predicting landslides in the Waitakere Ranges Regional Park in New Zealand.
Claessens has discovered that the kauri trees in New Zealand prevent landslides. When these enormous conifers reached a certain age, they stabilise areas prone to landslides. This maximises the benefit the trees gain by living far longer than other tree species.
At present the slopes are drained and large concrete structures are placed to prevent the landslides and the associated mud flows. According to Claessens planting kauri trees is a natural and in the longer-term possibly better solution for this problem.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
