Wave energy integration costs should compare favorably to other energy sources
A new analysis suggests that large-scale wave energy systems developed in the Pacific Northwest should be comparatively steady, dependable and able to be integrated into the overall energy grid at lower costs ...
New seismic survey technique could save dolphins' hearing
Conventional seismic imaging transmits sound energy into the ground and builds a picture of the underlying geology by analysing how the energy waves are reflected back to the receiver.
Comet landing named Physics World 2014 Breakthrough of the Year
The first ever landing of a man-made probe onto a comet has been named Physics World Breakthrough of the Year for 2014.
Tidal turbine success signals buoyant future for marine-based energy
A scaled down floating tidal turbine has been successfully put to sea off the Orkney Islands in Scotland, an achievement that represents a significant milestone in the development of a viable European marine-based ...
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.
Unravelling the mystery of gamma-ray bursts
A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space 'microphones'.
Researchers develop new acoustic sensor for chemical and biological detection
Testing for ovarian cancer or the presence of a particular chemical could be almost as simple as distinguishing an F sharp from a B flat, thanks to a new microscopic acoustic device that has been dramatically ...
Researchers create and control spin waves, lifting prospects for enhanced info processing
A team of New York University and University of Barcelona physicists has developed a method to control the movements occurring within magnetic materials, which are used to store and carry information. The breakthrough could ...
POLARBEAR seeks cosmic answers in microwave polarization
An international team of physicists has measured a subtle characteristic in the polarization of the cosmic microwave background radiation that will allow them to map the large-scale structure of the universe, ...
Laser physics upside down
At the Vienna University of Technology a system of coupled lasers has been created which exhibits truly paradoxical behaviour: An increase in energy supply switches the lasers off, reducing the energy can ...
Dancing beads on surface waves cluster in surprising ways
(Phys.org) —FOM researchers have discovered that objects floating on surface waves behave differently than expected. If a small number of floating objects is present on a water surface, these will drift ...
Team uses unused iPhone energy for case lights
How plants adapt: Calcium waves help the roots tell the shoots
For Simon Gilroy, sometimes seeing is believing. In this case, it was seeing the wave of calcium sweep root-to-shoot in the plants the University of Wisconsin-Madison professor of botany is studying that ...
Pioneering research offers new insight into improved wave energy testing
Pioneering research could provide a significant boost in the vital quest to harness wave power as a viable renewable energy source for the future.
