Errors on Viking sun compass hint at alternative purpose
Fabric circuit boards that can take bending, washing, stretching and bullets fired at them
Researchers suggest Vikings used crystals with sun compass to steer at night
Shipwreck find could be legendary 'sunstone'
An oblong crystal found in the wreck of a 16th-century English warship is a sunstone, a near-mythical navigational aid said to have been used by Viking mariners, researchers said on Wednesday.
How can we protect our information in the era of cloud computing?
Private information would be much more secure if individuals moved away from cloud-based storage towards peer-to-peer systems, where data is stored in a variety of ways and across a variety of sites, argues ...
Study finds a natural impediment to the long-term sequestration of carbon dioxide
Carbon sequestration promises to address greenhouse-gas emissions by capturing carbon dioxide from the atmosphere and injecting it deep below the Earth's surface, where it would permanently solidify into ...
Better forecasts for sea ice under climate change
University of Adelaide-led research will help pinpoint the impact of waves on sea ice, which is vulnerable to climate change, particularly in the Arctic where it is rapidly retreating.
Small islands may amplify tsunamis
Small islands, long thought to be natural tsunami barriers for coast-dwellers, may in fact amplify the waves they are supposed to break, researchers warned Wednesday.
Adding uncertainty to improve mathematical models
Mathematicians from Brown University have introduced a new element of uncertainty into an equation used to describe the behavior of fluid flows. While being as certain as possible is generally the stock and ...
Mathematicians analyse new 'racetrack memory' computer device
(Phys.org) —Competition to create the smallest, lightest and cheapest laptop on the market is motivating the ongoing search for a better computer-memory device then the current, conventional 2D hard-disk ...
Discovery is key to metal wear in sliding parts (w/ Video)
Researchers have discovered a previously unknown mechanism for wear in metals: a swirling, fluid-like microscopic behavior in a solid piece of metal sliding over another.
When does a physical system compute?
Can physical systems from bacteria to black holes act as a computer? A University of York computer scientist and colleagues from the universities of Oxford and Leeds address this question in newly published research which ...
