A new watermarking technology based on a system akin to the permutation rules used to solve the numeral puzzles known as Sudoku has been developed by computer scientists in Malaysia. Writing in the International Journal of Grid and Utility Computing the team reports how their system could resist attempts to "crop" the watermark in more than nine times out of ten cases.
Drought shriveled crops in the Midwest, massive wildfires raged in the West and East Coast cities sweltered. The summer of 2012 was a season of epic proportions, especially July, the hottest month in the history of U.S. weather record keeping. And it's likely that we'll continue to see such calamitous weather.
Researchers in the College of Engineering at Oregon State University have made a significant advance in the function of metal-insulator-metal, or MIM diodes, a technology premised on the assumption that the speed of electrons moving through silicon is simply too slow.
Researchers from the universities in Mainz, Frankfurt, Hamburg, and Ulm have proposed a new platform for quantum simulation. In a theoretical paper recently published in Physical Review Letters, they show that a combined system of ultracold trapped ions and fermionic atoms could be used to emulate solid state physics.
Scientists at UC San Francisco are reporting that they have found a way to reverse some of the negative effects of aging on the brain, using a video game designed to improve cognitive control.
A team of researchers from the University of California, Riverside's Bourns College of Engineering have solved a problem that previously presented a serious hurdle for the use of graphene in electronic devices. Scanning electron microscopy image of graphene device used in the study. The scale bar is one micrometer. The UCR logo next to it is implemented with etched graphene.
It’s been a long weekend, and you might have what I call a vacation hangover. If you’re feeling a little foggy, you might assume you read that headlines wrong, but you didn’t.
A NASA-led team of scientists has uncovered strong evidence that soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age.
The research, published Sept. 3 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate.
A collaborative project involving a Kansas State University ecologist has shown that the Clean Air Act has helped forest systems recover from decades of sulfur pollution and acid rain.
Although greenhouse gases and aerosols have very distinct properties, their effects on spatial patterns of rainfall change are surprisingly similar, according to new research from the University of Hawaii at Manoa's International Pacific Research Center (IPRC) and Scripps Institution of Oceanography. The study is published in the September 1 online issue of Nature Geoscience.
Nanosatellites are smartphone-sized spacecraft that can perform simple, yet valuable, space missions. Dozens of these little vehicles are now tirelessly orbiting the earth performing valuable functions for NASA, the Department of Defense and even private companies.
The disappearance of a legion of North American large animals 12,900 years ago may be attributed to the impact. The results may have forced man's ancestors to move from hunting to a hunter-gather society, the first indications of an argicultural society thus being a direct consequence of this cataclysmic event.
A person's intensity of Facebook use can be predicted by activity in a reward-related area of the brain, according to a new study published in the open-access journal Frontiers in Human Neuroscience.
If you're eating better and exercising regularly, but still aren't seeing improvements in your health, there might be a reason: pollution. According to a new research report published in the September issue of The FASEB Journal, what you are eating and doing may not be the problem, but what's in what you are eating could be the culprit.
Data from a NASA airborne science mission reveals evidence of a large and previously unknown canyon hidden under a mile of Greenland ice. The canyon has the characteristics of a winding river channel and is at least 460 miles (750 kilometers) long, making it longer than the Grand Canyon.
Engineering plastics possess superior mechanical, chemical and thermal properties along with light weight and high strength characteristics that allow these plastics to replace metals and glass in many applications. The use of light weight engineering plastics in the automotive applications in lieu of heavier steel not only reduces vehicle weight but also increases fuel efficiency.
The ancient closest relatives of mammals – the cynodont therapsids – not only survived the greatest mass extinction of all time, 252 million years ago, but thrived in the aftermath, according to new research published today in Proceedings of the Royal Society B.
The radioactive ocean plume from the 2011 Fukushima nuclear plant disaster will reach the shores of the US within three years from the date of the incident but is likely to be harmless according to new paper in the journal Deep-Sea Research 1.
Research by environmental scientists at the Harvard School of Engineering and Applied Sciences (SEAS) brings bad news to the western United States, where firefighters are currently battling dozens of fires in at least 11 states.
If you are an Arsenal supporter that goes without saying, but judging by this first person/robot view at the recent Robocup, our robot overlords will need the next thirty years to catch up to us humans.
You can dive into the science and plenty of action from the last five years that the B-Human team, featured here, has been trying to bend it like Beckham.
