"After the Hiroshima, Fukushima, and Chernobyl nuclear disasters, fields of sunflowers were planted across the affected landscapes to help absorb toxic metals and radiation from the soil.

"Beavers are known for their ability to transform ecosystems by building dams and creating wetlands. In Nevada, beavers have been instrumental in restoring the desert river ecosystem by creating a series of dams that slow the flow of water and allow it to spread out, which helps to replenish groundwater and create areas of wetland habitat. These wetlands can support a variety of wildlife, even during times of drought, and play a crucial role in maintaining the overall health of the ecosystem. The work of beavers in creating these wetlands can have far-reaching positive impacts on the local environment, including providing habitat for various species and improving water quality."

"They’re called crinkle crankles. A single leaf wall over that distance would need brick piers approx every 1.5-2m if it was a retaining wall it would need to be at least 9” wide (2 bricks). The crinkle crankle has more strength due to it’s curved nature so can be 4” wide or a single leaf of bricks. For the maths if we can assume they’re true semi-circles then each semi circle would be 1/2piD or 1.57D whereas a double leaf wall would be 2D for the same length D Therefore using 21.5% less bricks than a double leaf wall hope that clears things up"

"A village in the Italian Alps is finally basking in winter sunlight thanks to a giant mirror installed on a mountain top to reflect the sun’s rays into the main square.

Viganella, with a population of less than 200, lies in a valley so steep that each year from November 11 to February 2 it hardly receives any sunshine.

That was until Mayor Pierfranco Midali decided to do something about it.

Now a 5-metre (16-foot) high, 8-metre (26-foot) wide mirror tracks the sun’s movement and reflects its rays into Viganella’s historic piazza.

The mirror, which cost around 100,000 euros (67,000 pounds), was unveiled on Sunday to the delight of the inhabitants."
