Native plant gardening for species conservation
Declining native species could be planted in urban green spaces. Researchers from the German Centre for Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg (MLU), Leipzig University and other institutions describe how to use this great potential for species protection. In their most recent study, published in the journal Nature Sustainability, they recommend practical conservation gardening methods in a bid to restructure the horticultural industry and reverse plant species declines.

In Germany, this includes 70 percent of all plant species, with almost a third (27.5 percent) threatened, and 76 species are already considered extinct. Much of this loss can be attributed to the decline in natural habitats, in part due to increasing urbanization. Ten percent of the total area of Germany, for example, is settlement area.
However, it is precisely these settlement areas that hold enormous—albeit untapped—potential for nature conservation. After all, these areas include millions of private gardens, balconies and green roofs, as well as parks and other public green spaces. Researchers from iDiv, the Universities of Halle and Leipzig and other institutions propose using these potentially available areas for conservation gardening.
Joel Simon — Evolving Floor Plans
Evolving Floor Plans is an experimental research project exploring speculative, optimized floor plan layouts. The rooms and expected flow of people are given to a genetic algorithm which attempts to optimize the layout to minimize walking time, the use of hallways, etc. The creative goal is to approach floor plan design solely from the perspective of optimization and without regard for convention, constructability, etc. The research goal is to see how a combination of explicit, implicit and emergent methods allow floor plans of high complexity to evolve. The floorplan is ‘grown’ from its genetic encoding using indirect methods such as graph contraction and emergent ones such as growing hallways using an ant-colony inspired algorithm….
The results were biological in appearance, intriguing in character and wildly irrational in practice.

Russian scientists prepare to explore the most alien lake on Earth
Buried over two miles beneath the East Antarctic Ice sheet lurks Lake Vostok — an isolated body of subglacial water, removed from the rest of the world for more than twenty million years. Now, Russian researchers are just a few meters of ice away from entering an environment unlike any we’ve ever seen… at least, not here on Earth.

‘Time cloak’ hid event in experiment, physicists say – The Washington Post
A team of physicists at Cornell University has created a wrinkle in time. Actually, it’s more like a teeny tiny moth hole in time. Inside it things can occur that are entirely undetectable, at least to ordinary observers. It’s as if they never happened.
This phenomenon, known as “temporal cloaking,” is the latest addition to a world that once existed only in children’s literature and science fiction — a place where objects are invisible and events are unrecorded.
