A new study focuses on the process that occurs when cancer cells interact with healthy cells in order to migrate around the body during metastasis. Scientists know that cancer cells recruit healthy cells and use them to travel long distances, but how this process takes place and how it could be controlled to design new …
Over the last six years, several teams of scientists have successfully treated people with a rare inherited eye disease by injecting a virus with a normal gene directly into the retina of an eye with a defective gene. Despite the invasive process, the virus with the normal gene was not capable of reaching all the …
The discovery of a Higgs-like boson with mass near 126 GeV, at the LHC, has reignited interest in future energy frontier colliders. We propose here a proton-proton (pp) collider in a 100 km ring, with center of mass (CM) energy of ~100 TeV which would have substantial discovery potential for new heavy particles and new …
Introducing the latest moonshot from Google[x]: balloon-powered Internet access. Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural and remote areas, help fill in coverage gaps and bring people back online after disasters. Many of us think of the Internet as a global community. But …
The theory underlying Mach effects – fluctuations of the restmasses of accelerating objects in which internal energy changes take place – and their use for propulsion is briefly recapitulated. Experimental apparatus based on a very sensitive thrust balance is briefly described. The experimental protocol employed to search for expected Mach effects is laid out, and …
Nextbigfuture covered the Metzger et al plan for Affordable, Rapid Bootstrapping of the Space Industry and Solar System Civilization back in April 2012. NASA has been talking about the plan. A fully functioning, remote system of robotic excavators and simple machinery still is years away from reality, and much research on asteroids needs to be …
China’s May exports rose 1 percent from a year earlier, down from 14.7 percent in April, while imports dropped 0.3 percent from a year earlier. The median estimates of analysts were for 7.4 percent export growth and 6.6 percent import gains. The $20.4 billion trade surplus compared with forecasts for $20 billion. The slowdown in …
Arxiv – A note on QUBO instances defined on Chimera graphs Dwave indicates Selby and Dash solved different problems Geordie Rose (CTO of Dwave Systems) indicates that the author of this paper solved the wrong problems. Neither Selby nor Dash were actually solving the problems the hardware solved, which is the source of the speed-ups …
If shale oil, shale gas and synthetic biofuels were to rapidly scale and significantly lower the price of oil this would have interesting geopolitical impacts on Russia. The Iran, Saudi Arabia impacts would also be interesting but a weaker Russian economy would matter more for geopolitics. 20-25% of Russia’s GDP is tied to the oil …
Rising wages in China are causing factories to shift to Taiwan and other parts of Asia. An increasing number of Taiwanese shifting at least some of their operations away from China – either to South East Asia or Taiwan – and adjusting their investment strategies in the mainland. One of the main reasons is a …
