If Alcubierre warp drive was feasible there would be big radiation problems

Universe Today has the full 11 page article, The Alcubierre Warp Drive: On the Matter of Matter by the University of Sydney The region of space behind a superluminally travelling warp bubble is almost entirely devoid of forward travelling particles, however it contains a sparse distribution of particles with greatly reduced energy. Meanwhile the region …

Resource Efficiency and a Circular Economy could save up to 3.7 trillion

The new McKinsey report Resource Revolution: Meeting the world’s energy, materials, food, and water needs shows that the resource challenge can be met through a combination of expanding the supply of resources and a step change in the way they are extracted, converted, and used. Such resource productivity improvements, using existing technology, could satisfy nearly …

Swimming through the blood stream: Stanford engineers create wireless, self-propelled medical device

Engineers at Stanford have demonstrated tiny implantable devices that could travel through the bloodstream. This week, at the International Solid-State Circuits Conference, before an audience of her peers, Ada Poon demonstrated a tiny, wirelessly powered, self-propelled medical device capable of controlled motion through a fluid – blood, to be exact. The era of swallow-the-surgeon medical …

Pregnant mothers at risk from air pollution

A Californian-based study has looked in detail at air quality and the impact of traffic-related air pollution on premature birth. Published in BioMed Central’s open access journal Environmental Health, results from this study show that traffic-related air pollution, especially polycyclic aromatic hydrocarbons (PAH), is associated with up to a 30% increase in premature births, and …

Cheap drugs could save thousands of lives – in Sweden alone

A major new international study involving researchers from the Sahlgrenska Academy and Sahlgrenska University Hospital has revealed that aspirin, statins, beta blockers and ACE inhibitors are prescribed far too infrequently. They are cheap, preventive medicines that could prevent a huge number of deaths from heart attacks and strokes. The study identifies aspirin, statins (cholesterol-lowering medication), …

Different views of the tablet future for Android and Apple

Sasha Pallenberg from the specialist Internet site Netbooknews has repeated his prediction that sales of tablet computers using Android would surpass those of the iPad by the end of next year. This prediction seems to be for unit sales volume and depends upon the success of $100 and cheaper tablets and $200 tablets. Dollar volume …

Updated paper – metamaterial warp drive simulator

Example of a non-reciprocal bi-anisotropic metamaterial geometry, which explicitly violates spatial and time reversal symmetries. An elementary unit of the split ring-based “perfect magnetoelectric metamaterial” design is supplemented with a magnetized ferrite particle. The particle is magnetized and shifted along the x-direction with respect to the center of the split ring. The particle magnetization is …
