Life-like cells are made of metal PDF Print E-mail

Could living things that evolved from metals be clunking about somewhere in the universe? Perhaps. In a lab in Glasgow, UK, one man is intent on proving that metal-based life is possible.

He has managed to build cell-like bubbles from giant metal-containing molecules and has given them some life-like properties. He now hopes to induce them to evolve into fully inorganic self-replicating entities.

"I am 100 per cent positive that we can get evolution to work outside organic biology," says Lee Cronin at the University of Glasgow. His building blocks are large "polyoxometalates" made of a range of metal atoms – most recently tungsten – linked to oxygen and phosphorus. By simply mixing them in solution, he can get them to self-assemble into cell-like spheres.

Giant ocean whirlpools puzzle scientists PDF Print E-mail

US scientists discovered two giant whirlpools in the Atlantic Ocean, off the coast of Guyana and Suriname. It became a sensational discovery because this part of the ocean has been studied thoroughly, and no one expected anything like that to appear in the area.
More importantly, no one can understand where the whirlpools came from and what surprises they may bring to people.

Saturn's moon Enceladus is giant heat source PDF Print E-mail
zondag, 13 maart 2011 13:32
Saturn's ice-shrouded moon Enceladus is pumping out more heat from its southern pole than all the hot springs at Yellowstone, and scientists are at a loss to explain it.
The prodigious outpouring of energy significantly boosts the likelihood that an ocean of liquid is sealed beneath the moon's icy surface. Water, in turn, is considered a key ingredient for life. The new data isn't enough to nail down how large an ocean might exist on Enceladus, or its location beneath the ice.
