Oldest Evidence of Life on Earth Possibly Found in Australian Rocks. Ancient rocks found in a remote stretch of Western Australia may contain the world's oldest known evidence of life on land, a new study finds.
The 3.48-billion-year-old rocks are part of an area known as the Dresser Formation, located in Pilbara, Australia. During Earth's early years, the region might have been a volcanic caldera (a volcanic crater often resulting from an eruption) on a small island dotted with hot springs and ponds that were teeming with microbial life, said study lead author Tara Djokic, a doctoral candidate in geosciences at the University of New South Wales in Australia. Djokic and her colleagues found signs of microbial life embedded in rocks that form around hot springs, as well as in deposits in the ancient hot springs themselves.

The brain of a sperm whale is about 60% larger in absolute mass than that of an elephant. Recently, Manger  made the controversial claim that cetacean brains are large because they contain an unusually large number of thermogenic glial cells whose numbers increased greatly to counteract heat loss during a decrease in ocean temperatures in the Eocene-Oligocene transition. Earth - Tardigrades return from the dead. Earth - Plants talk to each other using an internet of fungus. It's an information superhighway that speeds up interactions between a large, diverse population of individuals.
It allows individuals who may be widely separated to communicate and help each other out. But it also allows them to commit new forms of crime. No, we're not talking about the internet, we're talking about fungi. Saihō-ji (Kyoto) Golden Pond, in the center of the moss garden.

No one would have believed in the last years of the nineteenth century that a rubbish dump being created would, in the space of a century, become a protected area.
Yet that is exactly what happened to what has come to be known as Glass Beach, just outside Fort Bragg in California. The residents there had no refuse collection so, with the sea so close by the solution seemed obvious – throw the garbage over the edge of the cliffs above their local beach. The burgeoning population of the town proceeded, with abandon reckless if not gleeful (after all, it must have been more fun than the usual taking out of the garbage) to do just that. 2016 Grow Wild seed packet give-away.
