The creation of Camp Century, from the outset, was an audacious scheme. Under the thick ice of Greenland, a scant 800 miles from the North Pole, the US military built a hidden base of ice tunnels, imagined as an extensive network of railway tracks, stretching over 2,500 miles, that would keep 600 nuclear missiles buried under the ice. Construction began in 1959, under cover of a scientific research project, and soon a small installation, powered by a nuclear reactor, nested in the ice sheet.

The island chain of Hawaii consists of several volcanoes, which are fed by a "hotspot". In geosciences a "hotspot" refers to a phenomenon of columnar shaped streams, which transport hot material from the deep mantle to the surface. Like a blow torch, the material burns through the Earth's crust and forms volcanoes. For a long time, it was assumed that these hotspots are stationary. If the tectonic plate moves across it, a chain of volcanoes evolves, with the youngest volcano at one end, the oldest at the other.

Cleaning up beaches could boost local economies in addition to preserving natural treasures and animal habitats.
In southern California’s Orange County alone, the economic benefits of beach cleanup could range from $13 per resident in a three-month period if debris were reduced by 25 percent to $42 per resident with a 75 percent drop in plastics and other trash along the oceanfront, according to a new study. That could mean up to a $46 million boost to the county’s economy in just one summer.

Researchers at the University of East Anglia have discovered a key gene for the synthesis of one of the world’s most abundant sulfur molecules.
Dimethylsulfoniopropionate (DMSP) is an important nutrient in marine environments with more than one billion tonnes produced annually by marine phytoplankton (microscopic plant-like cells), seaweed and bacteria.

New research published today in Nature Ecology & Evolution demonstrates the extraordinary value of Earth’s remaining intact forests for addressing climate change and protecting wildlife, critical watersheds, indigenous cultures, and human health. Yet the global policy and science communities do not differentiate among the relative values of different types of forest landscapes—which range from highly intact ones to those which are heavily logged, fragmented, burnt, drained and/or over-hunted—due in part to the lack of a uniform way of measuring their quality.
