The search for a faraway planet that could support life has found the most promising candidate to date, in the form of a distant world some 120,000 billion miles away from Earth.
Scientists believe that the planet is made of rock, like the Earth, and sits in the "Goldilocks zone" of its sun, where it is neither too hot nor too cold for water to exist in liquid form – widely believed to be an essential precondition for life to evolve.
Not too hot, not too cold: could the 'Goldilocks' planet support life?
Winds could explain Biblical parting of the Red Sea
Computer simulations show how the movement of wind could have parted the waters of the Red Sea The parting of the Red Sea, as described in the Bible, could have been a phenomenon caused by strong winds, according to new computer simulations.
The account in the Book of Exodus describes how the waters of the sea parted, allowing the Israelites to flee their Egyptian pursuers. Simulations by US scientists show how the movement of wind could have opened up a land bridge at one location.
Tightened muzzle on scientists is 'Orwellian'
The Harper government has tightened the muzzle on federal scientists, going so far as to control when and what they can say about floods at the end of the last ice age.
Natural Resources Canada (NRC) scientists were told this spring they need "pre-approval" from Minister Christian Paradis' office to speak with journalists. Their "media lines" also need ministerial approval, say documents obtained by Postmedia News through access-to-information legislation.
Tiny solar cells fix themselves
Researchers have demonstrated tiny solar cells just billionths of a metre across that can repair themselves, extending their useful lifetime. The cells make use of proteins from the machinery of plants, turning sunlight into electric charges that can do work. The cells simply assemble themselves from a mixture of the proteins, minute tubes of carbon and other materials.
The self-repairing mechanism, reported in Nature Chemistry, could lead to much longer-lasting solar cells. The design and improvement of solar cells is one of the most vibrant areas of science, in part because sunlight is far and away the planet's most abundant renewable energy source.
New Mars tests find possible life ingredients
Thirty-four years after NASA's Viking missions to Mars sent back results interpreted to mean there was no organic material - and consequently no life - on the planet, new research has concluded that organic material was found after all.
The finding does not bring scientists closer to discovering life on Mars, researchers say, but it does open the door to a greater likelihood that life exists, or once existed, on the planet.
Chemical basis for first life theorized
It's a chicken-and-the-egg puzzle: How could the basic biochemicals like amino acids and nucleotides have come about when there were no catalysts, like proteins or ribosomes, around to create them? Now scientists propose that a third type of catalyst could have jumpstarted metabolism and life itself, deep in hydrothermal ocean vents, an article in The Biological Bulletin says.
The scientists' theory says molecular structures involving transition metal elements -- iron, copper, nickel, etc. -- and ligands -- small organic molecules -- could have catalyzed the synthesis of basic biochemicals, monomers, that acted as building blocks for more complex molecules, leading ultimately to the origin of life.
Stephen Hawking: God did not create Universe
There is no place for God in theories on the creation of the Universe, Professor Stephen Hawking has said. He had previously argued belief in a creator was not incompatible with science but in a new book, he concludes the Big Bang was an inevitable consequence of the laws of physics.
The Grand Design, part serialised in the Times, says there is no need to invoke God to set the Universe going. "Spontaneous creation is the reason there is something," he concluded.
