Realizing quantum bits

In computers of the future, information might be stored in the form of quantum bits. But how can a quantum bit be realised?

Asymmetrical magnetic microbeads turned into micro-robots

Janus was a Roman god with two distinct faces. Thousands of years later, he inspired material scientists working on asymmetrical microscopic spheres—with both a magnetic and a non-magnetic half—called Janus particles. ...

Tuning the magnetic properties of multi-functional iron nanowires

Smart nanomaterials that respond to an external stimulus are a new breed of material that could shake up almost every area of science from healthcare to heavy industry. A research team led by King Abdullah University of Science ...

Unique nano-capsules promise the targeted drug delivery

Scientists have been engaged with drug delivery systems for a long time. Many "nano-carriages" for drug delivery to the desired location have been created, but many challenges remain, including preventing the medicine from ...

Magnetic nanoparticles may reveal early traces of cancer

Nanoscale magnets offer a new way to find faint, early traces of cancer in patients, according to Rice University students working on a method to capitalize on the magnets' properties. Three Rice computational and applied ...

Physicists discover flaws in superconductor theory

University of Houston physicists report finding major theoretical flaws in the generally accepted understanding of how a superconductor traps and holds a magnetic field. More than 50 years ago, C.P. Bean, a scientist at General ...
