There have been general assumptions that wealthy and urban people have small families. This is true for the hard working affluent. People who are upper middle class but have two working parents. Back in 2011, The New York Post wrote about the trend of large families in Manhattan, citing a study by the Council on …
A fundamental assumption of the study of economics is that human wants are unlimited. The economic problem is human wants are unlimited, but the means to satisfy human wants are scarce. The environmental problems the world faces are primarily because technologies of industry and energy are currently based on upgraded 18th and 19th century coal …
The United Nations (UN) recently released population projections based on data until 2012 and a Bayesian probabilistic methodology. Analysis of these data reveals that, contrary to previous literature, the world population is unlikely to stop growing this century. There is an 80% probability that world population, now 7.2 billion people, will increase to between 9.6 …
A new microscope system can image down to sub-nanometer resolution and will be able to reach 0.1 nanometer (angstrom) imaging of atoms. It works by boosting wavelength to ultra-high harmonics using an aperture reflection-mode microscope illuminated by a 30-nanometer source. Full-field images of 40-to-80 nanometer lateral resolution result an axial resolution of just six angstroms …
Demand for specialized integrated circuits for military electronics continues to surge exponentially with no end in sight. Systems that synchronize the activity of unmanned aerial vehicles; real-time conversion of raw radar data into tactically useful 3-D imagery; and instant access to high-resolution sensor feeds on the battlefield are only three examples of this reality. Despite …
Harnessing radical new tools—from ultrafast laser imagers to groundbreaking chemical synthesis approaches—DARPA’s Defense Sciences Office (DSO) is aggressively pursuing the development of novel materials with the potential to boost national security. One major challenge in developing new materials has been the difficulty of retaining and exploiting the unique characteristics that emerge in materials at the …
An Aug. 25 report in Beijing-based newspaper China Aviation News praised the engine division of Xi’an-based aeronautic and aerospace firm AVIC Qingan Group. The report mentions a planned project which would see the development of China’s first domestically-made turbofan-ramjet combined cycle engine, designed for an unnamed aircraft. The description of this engine suggests something resembling …
Over the next two decades the structure of world population and income will undergo profound changes. Global income inequality is projected to decline further in 2035, largely owing to rapid economic growth in the emerging-market economies. The potential pool of consumers worldwide will expand significantly, with the largest net gains in the developing and emerging-market …
Obesity is one of the biggest public health challenges of the 21st century. Affecting more than 500 million people worldwide, obesity costs at least $200 billion each year in the United States alone, and contributes to potentially fatal disorders such as cardiovascular disease, type 2 diabetes, and cancer. But there may now be a new …
Samsung SDI already had high capacity 2.9 Ah (29E) cells for E-bikes. High capacity cells such as 2.9 Ah improve the driving distance of the E-bike and provide convenience to the customers. Samsung SDI unveiled a 500Wh e-bike Li-ion battery pack that can run for 100 km on a single battery charge. Samsung SDI is …
Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and the University of California, Los Angeles have demonstrated a new, efficient way to accelerate positrons, the antimatter opposites of electrons. The method may help boost the energy and shrink the size of future linear particle colliders – powerful accelerators that could be …
