Researchers at the University of Pittsburgh have invented a new type of electronic switch that performs electronic logic functions within a single molecule. The incorporation of such single-molecule elements could enable smaller, faster, and more energy-efficient electronics. “This new switch is superior to existing single-molecule concepts,” said Hrvoje Petek, principal investigator and professor of physics …
Two talks at the 100 Year Starship conference held the key to the future, in the opinion of Adam Crowl. Adam Crowl is a designer on the Icarus Project. Project Icarus is a theoretical design study with the aim of designing a credible interstellar probe that will serve as a concept design for a potential …

Fossil fuel subsidies were $312 billion in 2009 and were $558 billion in 2008 The Fossil fuel consumption subsidies increase with higher oil prices. If oil subsidies were removed then oil demand would be 4.7 million barrels per day lower in 2020. China’s electricity demand is projected to triple from 2008 to 2035. China and …
From the Bulletin of the Atomic Scientist: The long-term ratio between the real price of oil and the real price of natural gas has constantly varied between 1 and 2 with the long-term average hovering at 1.6. Since January, however, that ratio has jumped to more than 4 to 1, which is unprecedented and has …
The 1000 meter helicopter supperted vertical raceway is now ready and waiting for the space elevator teams. More information on the upcoming schedule coming your way soon. Full altitude integrated tests were performed this past weekend. They performed a series of measurements in order to correlate helicopter positions and lasing angles. The trick is to …
P values were calculated by the log-rank test. Four per cent of the control mice and three per cent of rapamycin-assigned mice were removed from the experiment for technical reasons. Only five animals (three controls, two rapamycin) were removed after the start of rapamycin treatment at 600 days. Thus, there were no significant differences between …
The USA has the Very High Temperature Gen IV reactor candidate, which could have deep burn [65% of the nuclear material would be used instead of about 1% for current reactors] and temperatures up to 1000 degrees. High temperatures is efficient for providing heat for many industrial applications. The difference between the US and China …
The Chinese economy expanded a revised 13% in 2007 from a year earlier, up from an original estimate of 11.9%, the National Bureau of Statistics said in a statement on its Web site.
