Scientists at Hokkaido University have developed a device that employs both magnetic and electronic signals, which could provide twice the storage capacity of conventional memory devices, such as USB flash drives.
Conventional USB flash drives are electronic data storage devices. They store information by using millions of small gates that process information into "words" consisting of various combinations of the numbers 0 and 1.
A team of researchers from the Iowa State University in Ames, IA has demonstrated a proof-of-concept three-dimensional paper-based microbial fuel cell (MFC) that could take advantage of capillary action to guide the liquids through the MFC system and to eliminate the need for external power. Their report appears in the forthcoming issue of the journal TECHNOLOGY.
RESEARCH by a University of Huddersfield scientist could aid the development of new strains of wheat that yield higher quantities of extra-nutritious flour.
Professor Grant Campbell is a leading expert in cereal process engineering and is based in the University's School of Applied Sciences. The milling of wheat and the complexities of its kernel are central to his work. Now his latest co-authored article analyses the different breakage characteristics of hard and soft wheats.
COLUMBIA, Mo. - Soil and nutrient loss and runoff from agricultural fields are major problems environmentally and economically in the U.S. and globally. After heavy spring rains, soil and water runoff containing fertilizer and pesticides is washed downstream, carrying the sediment and chemicals to the Gulf of Mexico. This process creates a large oxygen-starved area which is toxic to aquatic organisms and damages the commercial fishing and tourism industries. Tree-based buffers are an effective method for preventing runoff, however they can negatively affect crop yields.
It's difficult to convince yourself to go out to that party when you won't know anybody there and your couch is so comfortable and your Xbox is sitting right there, begging to be played.
And while it's easy to justify taking the easy way out of an uncomfortable social situation and spending a night in playing *insert violent video game here*, a new study suggests that avoiding one party to play violent video games will make it even less likely that you'll go to the next.
When a team of researchers began listening in on seven sperm whales in the waters off the Azores, they discovered that the whales' characteristic tapping sounds serve as a form of individual communication. But what are they actually saying?
"They clearly have something on their minds - but to be perfectly honest, we haven't the faintest idea what that might be."
Is quantum technology the future of the 21st century? On the occasion of the 66th Lindau Nobel Laureate Meeting, this is the key question to be explored today in a panel discussion with the Nobel Laureates Serge Haroche, Gerardus 't Hooft, William Phillips and David Wineland. In the following interview, Professor Rainer Blatt, internationally renowned quantum physicist, recipient of numerous honours, Council Member and Scientific Co-Chairman of the 66th Lindau Meeting, talks about what we can expect from the "second quantum revolution".
Graphene, an allotrope of carbon, discovered more than a decade ago has led to myriad research that seeks to unlock its vast potential. Zeolites, commonly used microporous solid catalysts in the petrochemical industry, have recently attracted attention in the field of material science as a template for carbon synthesis. Each individual crystal is distinguished by its unique 1 nanometer (nm) sized pore structure, this structure facilitates the accommodation of carbon nanotubes inside the zeolite.
How can a gecko move across a ceiling upside down? Two mechanisms are responsible: Adhesion via billions of extremely fine hairs on its feet, which enable it to stick to ceilings and walls. And as soon as the gecko moves, it relies on stiction. However, any change of adhesion and stiction at macroscopic level is expressed on the nanometer scale through the change in the forces exerted between atoms and molecules.
How a drop of water touches a honeycomb structure
Global patterns of adoption spreading are induced by local adoption cascades initiated by multiple spontaneous adopters arriving at a constant rate, amplified by a large number of adoptions induced by social influence, and controlled by individuals who are immune to the actual adoption.
PROVIDENCE, R.I. [Brown University] -- One of the most basic components of any communications network is a power splitter that allows a signal to be sent to multiple users and devices. Researchers from Brown University have now developed just such a device for terahertz radiation -- a range of frequencies that may one day enable data transfer up to 100 times faster than current cellular and Wi-Fi networks.
When raindrops fall into bodies of water, milk is added to a cup of coffee, and in other mixing and rinsing processes, you might wonder how one liquid is absorbed by the other. Small droplets can be absorbed so fast that our minds perceive it to be instantaneous. However, in reality, there is much more to the process than first meets the eye.
Manufacturers of feminine hygiene products, including tampons and sanitary products, could dedicate a part of their revenues to support public health programmes that prevent violence against women, argues an expert in The BMJ this week.
Physical and sexual violence is a public health problem that affects more than one third of all women, equivalent to at least a billion women globally, according to a World Health Organization (WHO) study.
A small, squishy vehicle equipped with soft wheels rolls over rough terrain and runs under water.
Future versions of the versatile vehicle might be suitable for search and rescue missions after disasters, deep space and planet exploration, and manipulating objects during magnetic resonance imaging (MRI), according to its creators at Rutgers University.
Forget mousetraps -- today's scientists will get the cheese if they manage to build a better battery.
An international team led by Texas A&M University chemist Sarbajit Banerjee is one step closer, thanks to new research published today (June 28) in the journal Nature Communications that has the potential to create more efficient batteries by shedding light on the cause of one of their biggest problems -- a "traffic jam" of ions that slows down their charging and discharging process.
