Spin-polarised electrons on demand
Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Different...
Opinion: The benefits of an intercontinental energy grid
An electricity grid that stretched from Australia to China could collect and carry all of the renewable energy generated in between, and would represent a huge advance in the battle...
Next-generation cloaking device demonstrated
A device that can bestow invisibility to an object by "cloaking" it from visual light is closer to reality. read more
Spallation Neutron Source Gets Initial Go-Ahead on Second Target
The U.S. Department of Energy has given its initial approval to begin plans for a second target station for the Spallation Neutron Source, expanding what is already the world's most...
Surprising New Health and Environmental Concerns About Tungsten
Surprising new scientific research is raising concerns about the potential health and environmental hazards of tungsten -- a metal used in products ranging from bullets to light bulbs to jewelry...
Opinion: Converging technologies for biosecurity
The transmission of information and converging of technologies is an essential component of biosecurity, write Greg Tegart and Stephen Prowse.
Robot Inspects Wind Energy Converters
The material of wind energy converters must withstand intense forces. Are rotor blades damaged? A new robot inspects wind energy converters more precisely than a human ever could. It detects...
Silicon Chip Manufacture: Flat Fixtures For EUV Exposure
Exposing silicon wafers to light during chip manufacture requires special fixtures called chucks. Novel electrostatic chucks made of glass ceramics are incredibly flat. This prevents structural distortions on the exposure...

Inexpensive solar cells, vastly improved medical imaging techniques and lighter more flexible television screens are among the potential applications envisioned for organic electronics. Recent experiments may bring these closer thanks...
Lack Of Thermoelectric Effect Is Cool Feature In Carbon Nanotubes
Metallic carbon nanotubes have been proposed as interconnects in future electronic devices packed with high-density nanoscale circuits. But can they stand up to the heat?
Freezing water and what it can do: FAQs
Unlike most other substances, water expands when it freezes. This is due to its unique molecular structure, where one oxygen atom bonds with two hydrogen atoms.
Fate of The Source by Circuit City unclear as U.S. parent to close
Circuit City Stores Inc. will liquidate its 567 remaining U.S. stores, leaving the future of the company's Canadian subsidiary unclear.
