LangmuirNew process could advance use of healthy cells or stem cells to treat disease In a discovery that may help speed use of "cell therapy" -- with normal cells or stem cells infused into the body to treat disease -- scientists are reporting development of a way to deliver therapeutic human cells to diseased areas within the body using a simple magnetic effect. Their report appears in ACS' journal Langmuir. Contact: Michael Bernstein

Monitoring food with millimeter waves We may be able to see through glass, water and air, but not packing paper, plastic or cardboard. What remains hidden from the human eye is made visible by a new millimeter-wave sensor: Unlike x-ray scanners, it can see through non-transparent materials without sending out harmful rays.

Nature NanotechnologyBoron nanoribbons reveal surprising thermal properties in bundles Researchers looking at the thermal conductivity of bundles boron nanoribbons have found that they have unusually high heat-transfer capabilities. Contrary to past experiments with similar nanomaterial bundles, the study shows that the thermal conductivity of a bundle of boron nanoribbons can be significantly higher than that a single nanoribbon. Experimental results indicate that the geometry of the ribbons is responsible for the higher conductivity and point to potential method for creating a thermal switch.

NanotechnologyResearchers measure nanometer scale temperature Illinois researchers have developed a new kind of electro-thermal nanoprobe that can independently control voltage and temperature at a nanometer-scale point contact. It can also measure the temperature-dependent voltage at a nanometer-scale point contact.

NatureAalto University researchers demonstrate an almost noiseless nanomechanical microwave amplifier Physicists in Aalto University, Finland, have shown how a nanomechanical oscillator can be used for detection and amplification of feeble radio waves or microwaves. A measurement using such a tiny device, resembling a miniaturized guitar string, can be performed with the least possible disturbance. The results were recently published in the most prestigious scientific arena, the British journal Nature.

BiomaterialsNanoparticles help researchers deliver steroids to retina Hitching a ride into the retina on nanoparticles called dendrimers offers a new way to treat age-related macular degeneration and retinitis pigmentosa. A collaborative research study among investigators at Wayne State University, the Mayo Clinic and Johns Hopkins Medicine shows that steroids attached to the dendrimers targeted the damage-causing cells associated with neuroinflammation, leaving the rest of the eye unaffected and preserving vision.

Nature NanotechnologyThe smallest conceivable switch For a long time miniaturization has been the magic word in electronics. A team of physicists at the Technische Universitaet Muenchen, have now presented a novel molecular switch in the journal Nature Nanotechnology. Decisive for the functionality of the switch is the position of a single proton in a porphyrin ring with an inside diameter of less than half a nanometer. The physicists can set four distinct states on demand.
