A new technology enabling tiny machines called micro electromechanical systems to "self-calibrate" could make possible super-accurate and precise sensors for crime-scene forensics, environmental testing and medical diagnostics.
It turns out that watching paint dry might not be as boring as the old adage claims. A team led by Yale University researchers has come up with a new technique to study the mechanics of coatings as they dry and peel, and has discovered that the process is far from mundane.
Researchers have taken one more step toward understanding the unique and often unexpected properties of graphene, a two-dimensional carbon material that has attracted interest because of its potential applications in future generations of electronic devices.
Under the microscope, the bacteria start dividing normally, two cells become four and then eight and so on. But then individual cells begin "popping," like circus balloons being struck by darts.
This phenome...
Thin layers of oxide materials and their interfaces have been observed in atomic resolution during growth for the first time by researchers at the Center for Nanophase Materials Sciences at the Department of Energy's Oak Ridge National Laboratory, providing new insight into the complicated link between their structure and properties.
Spin ice can be used to examine exotic properties of magnetic systems. Surprising observations have been made by physicists working with Prof. Dr. Hartmut Zabel at the Ruhr-Universität, using magnetic islands only micrometres in size that are placed on a periodic lattice with honeycomb symmetry.
An international team of scientists led by groups from the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany, and from the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley has used ultrashort flashes of laser light to directly observe the movement of an atom's outer electrons for the first time.
The Optical Society (OSA) announced today the launch and publication of the first issue of its newest monthly journal, Biomedical Optics Express. With a focus on biomedical optics and photonics, Biomedical Optics Express joins OSA's diverse portfolio of 14 peer-reviewed optics journals.
Scientists hoping to understand how cells work may get a boost from a new technique to tag and image proteins within living mammalian cells.
The new technique, developed by a research team led by University of Illino...
An innovation that can help scientists observe a reaction moving at greater than 10 meters per second, with a few nanometers spatial resolution, is a feat some would say is nearly impossible.
