New study forecasts sharp increase in world oil production capacity, and risk of price collapse
(Phys.org) -- Oil production capacity is surging in the United States and several other countries at such a fast pace that global oil output capacity is likely to grow by nearly 20 percent by 2020, which could prompt a plunge ...
Renewables can fill 80 percent electricity demand in U.S. in 2050
New twist on old chemical process could boost energy efficiency
Chemical reactions on the surface of metal oxides, such as titanium dioxide and zinc oxide, are important for applications such as solar cells that convert the sun's energy to electricity. Now University of ...
Carbon dioxide emissions reach record high
Emissions of heat-trapping carbon dioxide reached an all-time high last year, further reducing the chances that the world could avoid a dangerous rise in global average temperature by 2020, according to the International ...
Two new excited states of the Lambda-b beauty particle observed by LHCb
In beautiful agreement with the Standard Model, two new excited states of the Λb beauty particle have just been observed by the LHCb Collaboration. Similarly to protons and neutrons, Λb is composed of three qua ...
Graphite enters different states of matter
(Phys.org) -- For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second).
Spain the dunces in international science test
Spaniards came bottom of the class in an 11-nation science test and nearly half of them could not name a single important scientist in history, a survey showed Tuesday.
US greenhouse gases back up after decline
US emissions of greenhouse gases blamed for climate change rose in 2010, ending a brief downward turn as the world's largest economy gradually recovers from recession, official data showed Monday.
US grabs lead over China in clean energy race
The United States has regained the lead in the clean energy race, investing $48 billion last year to surpass China, which held the world's top spending spot since 2009, said a study Wednesday.
Generating first-ever controlled ultrafast radiation, using a plasma
To observe ultrarapid phenomena such as the motion of electrons within matter, researchers need sources capable of producing extremely fast and energetic light radiation. Although devices capable of emitting ...
Dance like a neutrino: Quantum scheme to simulate neutrino oscillations
The behaviour of some of the most elusive particles in the known universe can be simulated using three atoms in a lab, researchers at the Centre for Quantum Technologies (CQT) at the National University of Singapore have ...
