Washington DC (UPI) Oct 18, 2018
The Brazilian production of electricity from biomass, mostly produced from sugar cane material and then fed into the country's power grid, increased 11 percent during January-August from a year earlier. The country's association of sugar cane producers, know as Unica for its Portuguese acronym, said that the total biomass generation from January to August has reached 17,291 gigawatt-hou

Delft, Netherlands (SPX) Oct 19, 2018
A quantum internet may very well be the first quantum information technology to become reality. Researchers at QuTech in Delft, The Netherlands, have published a comprehensive guide towards this goal in Science. It describes six phases, starting with simple networks of qubits that could already enable secure quantum communications - a phase that could be reality in the near future. The dev

Santa Cruz CA (SPX) Oct 19, 2018
Scientists at UC Santa Cruz and Lawrence Livermore National Laboratory (LLNL) have reported unprecedented performance results for a supercapacitor electrode. The researchers fabricated electrodes using a printable graphene aerogel to build a porous three-dimensional scaffold loaded with pseudocapacitive material. In laboratory tests, the novel electrodes achieved the highest areal capacita

Shanghai (AFP) Oct 19, 2018
Three of China's top financial officials launched a coordinated attempt to shore up confidence in the country's stock markets and economic prospects on Friday in an unusual expression of top-level concern over what one of them called "abnormal" share price falls. The timing of the rare intervention by the heads of the central bank, securities commission and banking regulator - in interview

Washington (AFP) Oct 17, 2018
Beijing is not a currency manipulator but China's exchange rate practices and the yuan's recent decline are of "particular concern," US Treasury Steven Mnuchin said Wednesday. In putting Beijing and five other US trading partners on notice, the Treasury again refrained from escalating a fight over China's currency as US President Donald Trump had once pledged to do on the campaign trail.

Sydney (AFP) Oct 18, 2018
The trade spat between the world's two largest economies - China and the United States - is imperilling the entire Asia-Pacific, regional finance ministers have warned. In a statement, finance ministers meeting in Port Moresby said risks to the global economy had increased thanks to "heightened trade and geopolitical tensions", a veiled reference to the tit-for-tat trade dispute between W

Carbon fiber can store energy in the body of a vehicle

Gothenburg, Sweden (SPX) Oct 19, 2018
A study led by Chalmers University of Technology, Sweden, has shown that carbon fibres can work as battery electrodes, storing energy directly. This opens up new opportunities for structural batteries, where the carbon fibre becomes part of the energy system. The use of this type of multifunctional material can contribute to a significant weight-reduction in the aircraft and vehicles of the futu

Washington DC (UPI) Oct 18, 2018
Projections of $100 oil at the end of 2018 were the rage just a few weeks ago. It remains to be seen what will happen with U.S. relations with Saudi Arabia and whether sanctions against Iran will put a kink in global supplies next month. But for now, crude oil prices are retreating from September highs. WTI crude oil prices fell below $70 a barrel while Brent prices slipped below

Wissenschaftler aus Würzburg und Kairo untersuchen in einem neuen Forschungsprojekt eine mehr als 4.500 Jahre alte Pyramidenanlage in Ägypten. Unter den Überresten früherer Grabungen haben sie einen Verbindungsweg zwischen zwei Tempeln und der Pyramide des Pharao Sahurê freigelegt. Von der Untersuchung der den Weg säumenden Reliefsteine erhoffen sich die Forscher neue Erkenntnisse zur altägyptischen Wirtschaft und Verwaltung.
