A novel device simply and conveniently traps, detects and manipulates the single spin of an electron, overcoming some major obstacles that have prevented progress toward spintronics and spin-based quantum computing.
Scientists suspect that iron accumulation plays a role in neurodegenerative processes such as Parkinson‚??s disease, but its distribution in neurons has never been observed because of the lack of techniques to do so. Until today.
Researchers have created the first nanoparticle capable of detecting and imaging trace amounts of hydrogen peroxide in animals. The nanoparticles, thought to be completely nontoxic, could someday be used as a simple, all-purpose diagnostic tool to detect the earliest stages of any disease that involves chronic inflammation, including cancer, Alzheimer's disease, heart disease, and arthritis.
By linking gold nanorods to an antibody that binds to tumor cells, researchers have found that gold nanorods will align themselves in an ordered fashion on the surface of cancer cells, further intensifying the optical signal the nanorods produce and providing a unique optical signature for tumor cells.
As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy from the environment.
The French Atomic Energy Commission (CEA) has given its backing to the European Charter for Researchers and the Code of Conduct for the Recruitment of Researchers, agreeing to apply their principles to its human resources management for researchers and scientific employment.
Using enzymes from E. coli bacteria, Duke University chemists and engineers have introduced a hundred-fold improvement in the precision of features imprinted to create microdevices such as labs-on-a-chip.
The Jaap Schijve Award has been established and is sponsored by the Dutch National Aerospace Laboratory (NLR) and Delft University of Technology in the Netherlands. This prize of 5000 Euro is awarded to a young researcher who has made an outstanding contribution to scientific progress in fatigue and damage tolerance as applied to aerospace.
With the help of a device capable of depositing metals an atom at a time in the materials used in computer chips, a team of engineers has successfully blended modern semiconductor technology and nanomachines.
