Frog 

Scientists in the United States claim to have created the world’s first living robots using stem cells from frog embryos. The tiny hybrids, designed on a supercomputer at the University of Vermont (UVM) and then assembled by biologists at Tufts University, are “entirely new life-forms” known as xenobots. “These are novel living machines,” said Joshua Bongard, a computer scientist and robotics expert at the UVM who co-led the research. “They’re neither a traditional robot nor a known species of animal. It’s a new class of artefact: a living, programmable organism.”

Lowline Underground Park

An abandoned subway terminal in New York City is being pitched for redevelopment into a sunlit, subterranean park -- replete with 60,000 square feet of flowers, ponds and trees. Located in Manhattan's trendy Lower East Side, the vast underground space -- which is about the size of a football field -- has remained untouched since the terminal was discontinued back in 1948.  Now, a group of entrepreneurs are proposing an elaborate green makeover, in which sunlight would be "harvested" above ground and channeled into the vaults below via a network of fiber-optic cables -- creating an environment apparently filled with natural light and, in theory, ripe for growing all the foliage of a typical city park.

But nothing is headed for a landfill. Instead, what’s next is a process that could revolutionize recycling.

Single Le Tres Chic Toilette 

The public urinal that turns pee into compostIt may be better known as the city of light and of love, but Paris is also – and all too often – the city of pee, and consequently of pong. But the French capital has a new weapon in its longstanding battle against les pipis sauvages, or wild peeing, the time-honoured if technically prohibited practice of urinating in the street, and its unsavoury accompanying odours.
