The idea of a "digital divide" -- describing those who can or cannot get on the Internet -- has been around since the 1990s. Although, it used to refer mostly to access, now it often also means the quality and speed of Internet access -- and the skills to make use of the technology.
A shortage of auto parts and other components after Japan's earthquake has stirred unease about two pillars of manufacturing: the country's role as a crucial link in the global supply chain and "just in time" production.
The film tells the story of two ordinary people who are taken into a top-secret military hibernation experiment that goes awry, and awaken 500 years in the future. They discover that the world has degenerated into a dystopia where advertising, commercialism, and cultural anti-intellectualism run rampant and dysgenic pressure has resulted in a uniformly stupid human society devoid of individual responsibility or consequences.
Coating concrete destined to rebuild America's crumbling bridges and roadways with some of the millions of tons of ash left over from burning coal could extend the life of those structures by decades, saving billions of dollars of taxpayer money, scientists reported here today at the 241st National Meeting & Exposition of the American Chemical Society. They reported on a new coating material for concrete made from flyash that is hundreds of times more durable than existing coatings and costs only half as much.
The authors of a recent Perspectives piece in the journal Nature Climate Science say it is not enough to intuit the success of climate communications. They contend the evaluation of climate communication should be met with the same rigor as climate science itself. Here, someone uses the 220 megapixel HiPerWall display at the University of California, San Diego to discuss 10 time varying Intergovernmental Panel on Climate Change simulation runs.
After six years of intensive effort, scientists are reporting development of the first commercially viable nanogenerator, a flexible chip that can use body movements - a finger pinch now en route to a pulse beat in the future - to generate electricity. Speaking here today at the 241st National Meeting & Exposition of the American Chemical Society, they described boosting the device's power output by thousands times and its voltage by 150 times to finally move it out of the lab and toward everyday life.
Ranchers in the central Great Plains may be using some of their winter downtime in the future to rehearse the upcoming production season, all from the warmth of their homes, according to U.S. Department of Agriculture (USDA) soil scientists.
The environmental concern is great when considering the role of toxic contaminants in the plant-soil relationship. Understanding plant's absorption and accumulation of these contaminants from the soil would be incredibly beneficial.
Japan relies on nuclear power for about 30% of its electricity. It has few natural resources and imports large quantities of coal, gas and oil at an ever increasing cost. Some Japanese people are not in favor of nuclear power, but when the dust settles the nation might not have any real choice, writes Professor George Dracoulis.
Perhaps lost in the recent debates related to the earthquake and tsunami in Japan is that natural disasters and not nuclear energy should be the focus, says Oak Ridge National Laboratory's John Sorensen, an emergency preparedness expert.
Researchers are testing the biofuel on a NASA DC-8 to measure its performance and emissions as part of the Alternative Aviation Fuel Experiment II, or AAFEX II. The fuel is called Hydrotreated Renewable Jet Fuel.
North and South Korea held talks on Tuesday about a potential volcanic threat from the peninsula's highest mountain, in a rare interlude of cooperation after months of confrontation.
Labeling products with information on the size of the carbon footprint they leave behind could help both consumers and manufacturers make better, environmentally friendly choices.
Researchers at Mount Sinai School of Medicine have found that patients with Alzheimer's disease have lower glucose utilization in the brain than those with normal cognitive function, and that those decreased levels may be detectable approximately 20 years prior to the first symptoms of Alzheimer's disease. This new finding could lead to the development of novel therapies to prevent the eventual onset of Alzheimer's. The study is published online in the journal Translational Neuroscience.
EU commissioner for Transport Sim Kallas gestures during his press conference on the white paper on the future transport at the EU Headquarters in Brussels. Europe's transport network will need a 1.5-trillion-euro private sector overhaul to meet the demands of a post-oil, post-emissions world, the European Commission said Monday.
Warmer air is only part of the story when it comes to Greenland's rapidly melting ice sheet. New research by scientists at Woods Hole Oceanographic Institution (WHOI) highlights the role ocean circulation plays in transporting heat to glaciers.
The largest continuous expanse of forest in the world, found in the country's cold northern regions - is undergoing an accelerating large-scale shift in vegetation types as a result of globally and regionally warming climate. That in turn is creating an even warmer climate in the region, according to a new study published in the journal Global Change Biology and highlighted in the April issue of Nature Climate Change.
Original theories were that, while sleeping, our minds were essential empty slates with little neurological activity. However, this recent study provides evidence that during sleep, our body replays the cognitive and motor skills learned throughout the preceding day. Providing evidence of this 'replay' hypothesis was the goal of this study.
