If there was a tougher moment over the last 40 years to be a leader in the American environmental movement, it would be hard to put your finger on it.
New results from a look into the split second after the Big Bang indicate the universe is 80 million years older than previously thought but the core concepts of the cosmos — how it began, what it’s made of and where it’s going — seem to be on the right track. The findings released Thursday…
A 5,500-year-old tomb possibly belonging to a Stone Age chieftain has been unearthed at a megalithic monument in the shape of a ship called the Ale’s Stenar (Ale’s Stones). The tomb, in Sweden, was likely robbed of stones to build the Viking-era ship monument. “We found traces — mostly imprints — of large boulders,” said…
U.S. astronomers say they’ve observed a young star with a rotating dust disk considered the youngest still-forming planetary system ever found. The infant star surrounded by a swirling disk of dust and gas is more than 450 light-years from Earth in the constellation Taurus, the National Radio Astronomy Observatory reported. While just one-fifth the mass…
Department Of Energy chief Steven Chu says research will reshape the future of energy, enabling electricity grids that run on renewable energy and batteries and vehicles that are both more efficient and powerful.
A new view of the solar system’s early days proposes that the first two kinds of solid materials — the precursors of space rocks and ultimately planets — both formed at the same time. When the sun was born about 4.6 billion years ago, it was surrounded by a cloud of gas and dust that…
The “uncrackable codes” made by exploiting the branch of physics called quantum mechanics have been sent down kilometres of standard broadband fibre. This “quantum key distribution” has until now needed a dedicated fibre separate from that used to carry data. The technique, reported in Physical Review X, shows how to unpick normal data streams from…
