Zachary Gagnon, Jill Mazur, and Hsueh-Chia Chang We introduce a method for improved dielectrophoretic (DEP) discrimination and separation of viable and nonviable yeast cells. Due to the higher cell wall permeability of nonviable yeast cells compared with their viable counterpart, the cross-linking agent glutaraldehyde (GLT) is shown to selectively ...

By combining Fourier transform spectroscopy with two frequency-shifted combs and cavity ring-down spectroscopy, scientists demonstrate a powerful new tool for ultrahigh sensitivity spectroscopy. The scheme can measure broadband, high-resolution spectra in tens of microseconds, does not require detector arrays and may allow tuning from terahertz to ultraviolet frequencies.

Nanoscience has the potential to play an enormous role in enhancing a range of products, including sensors, photovoltaics and consumer electronics. Scientists in this field have created a multitude of nano scale materials, such as metal nanocrystals, carbon nanotubes and semiconducting nanowires.

Yesterday I attended a last-minute session at which NIH folks presented potential new changes to the way FOAs are released, the idea being that shorter, simpler applications deserve shorter, simpler funding announcements.

In his report in Science Magazine, MIT Professor of Mechanical Engineering and External Professor at Santa Fe Institute Seth Lloyd reports on his findings which show that a quantum-physics property called entanglement can be harnessed to make detectors--similar in principle to radar systems used to track airplanes in flight or ships at sea--that are as much as a million times more efficient than e

H. Y. Lv, H. J. Liu, L. Pan, Y. W. Wen, X. J. Tan et al. The electronic properties of (SbBi)Te compound are examined by using the full-potential linearized augmented plane-wave method. The transport coefficients are then calculated within the semiclassical Boltzmann theory, and further evaluated as a function of chemical potential assuming a rigid band pi ... [Appl. Phys.

We developed an enhanced green-emitting luciferase (ELuc) to be used as a bioluminescence imaging (BLI) probe. ELuc exhibits a light signal in mammalian cells that is over 10-fold stronger than that of the firefly luciferase (FLuc), which is the most widely used luciferase reporter gene.

New twist on powerful analytic method makes it much more useful

One of the attractions in studying oxide heterostructures is the unusual physical phenomena that they enable. It is now demonstrated that the enforced cation ordering in thin oxide superlattices leads to significantly enhanced magnetic ordering temperatures.

Current imaging modalities lack sufficient sensitivity and specificity for the noninvasive staging of lymph nodes in genitourinary cancers. In this Review, Mouli and colleagues from Northwestern University discuss the potential role of lymphotropic nanoparticles—which selectively accumulate in benign lymph nodes—in enhancing the MRI detection of nodal metastases.

Geochemical analyses and climate modelling suggest that 2.5 billion years ago much of the nitrogen now stored in the solid Earth was in the atmosphere, and that the higher atmospheric nitrogen levels would have increased the efficacy of greenhouse gases, thus warming the Earth.

D. an der Brugge and A. Pukhov It is shown that when a few-cycle, relativistically intense, p-polarized laser pulse is obliquely incident on overdense plasma, the surface electrons may form ultrathin, highly compressed layers with a width of a few nanometers. These electron nanobunches emit synchrotron radiation coherently. We ca ... [Phys. Plasmas 17, 033110 (2010)] published Wed Mar 31, 2010.

The U.S. Army Research Development and Engineering Command (REDCOM) have ordered 660 Enhanced Night Vision Goggles (ENVG) from three manufacturers for testing, toward massive fielding of new ENVGs in upcoming years. The awarded companies are ITT, L-3 Insight Technology and DRS Systems.

We introduce a new method for purifying recombinant proteins expressed in bacteria using a highly specific, inducible, self-cleaving protease tag. This tag is comprised of the Vibrio cholerae MARTX toxin cysteine protease domain (CPD), an autoprocessing enzyme that cleaves exclusively after a leucine residue within the target protein-CPD junction. Importantly, V. cholerae CPD is specifically activated by inositol hexakisphosphate (InsP6), a eukaryotic-specific small molecule that is absent from the bacterial cytosol.

Small, controllable, highly accessible quantum systems can serve as probes at the single-quantum level to study a number of physical effects, for example in quantum optics or for electric- and magnetic-field sensing. The applicability of trapped atomic ions as probes is highly dependent on the measurement situation at hand and thus calls for specialized traps. Previous approaches for ion traps with enhanced optical access included traps consisting of a single ring electrode or two opposing endcap electrodes. Other possibilities are planar trap geometries, which have been investigated for Penning traps and radiofrequency trap arrays. By not having the electrodes lie in a common plane, the optical access can be substantially increased. Here, we report the fabrication and experimental characterization of a novel radiofrequency ion trap geometry.
