When dark energy turned on (Update)

(PhysOrg.com) -- Some six billion light years distant, almost halfway from now back to the big bang, the universe was undergoing an elemental change. Held back until then by the mutual gravitational attraction of all the matter it contained, the universe had been expanding ever more slowly. Then, as matter spread out and its density decreased, dark energy took over and expansion began to accelerate.

Denmark announces plans to produce 100% of its energy from renewable sources by 2050

Here at Inhabitat, we are big fans of Denmark. Not only did they give the world Lego, but they have been innovative green designers and supporters of renewable energy. This week, the Danish government once again threw down the energy gauntlet by pledging to supply 35% of its total energy from renewables by 2020 and 100% by 2050.

Runaway planets zoom at a fraction of light speed

Seven years ago, astronomers boggled when they found the first runaway star flying out of our galaxy at a speed of 1.5 million miles per hour. The discovery intrigued theorists, who wondered: If a star can get tossed outward at such an extreme velocity, could the same thing happen to planets?

Liquid-like materials may pave way for new thermoelectric devices

In the continual quest for better thermoelectric materials -- which convert heat into electricity and vice versa -- researchers have identified a liquid-like compound whose properties give it the potential to be even more efficient than traditional thermoelectrics.
