Diamonds have always been alluring, but now a team of scientists has made them truly magnetic -- on the nanoscale.
In a paper published in the Aug. 26 issue of Physical Review Letters, the researchers report a technique to make magnetic diamond particles only 4-5 nanometers across. The tiny diamond magnets could find use in fields ranging from medicine to information technology.
Ferromagnetism has been historically reserved for metals, but scientists are becoming increasingly interested in the prospect of creating metal-free magnets, particularly from carbon-based materials. Diamond is a naturally occurring crystalline form of carbon.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
