The Universe in 3D, and more...

What's in the Universe? Talk about the biggest project ever! The Sloan Digital Sky Surveys, conducted over the past decade and still in progress, created a huge 3D map of part of the universe. Not only does the color map provide visual information of what galaxies are where, but their arrangement provides clues to the location and arrangement of dark matter. They looked at the brightness of 900,000 luminous galaxies (most of them ancient red galaxies), as observed at five different wavelengths by the Baryon Oscillation Spectrographic Survey. This allowed the researchers to measure the galaxies' redshift, and infer the location of dark matter based on the clumping of luminous matter.   ATS 300GM Fluorometer Detects Uranium at 0.1ppb Advanced Technical Services GmbH For All Your Scientific Supply/Equipment Needs Cynmar Corporation The ATS300GM Fluorometer (originally the Jarrell-Ash G-M Fluorometer) is a versatile laboratory analyzer re-engineered for precision, convenience and speed.

The Cary 630 FTIR offers permanently aligned optics that increase uptime with snap and go modules that improve testing. Download the new Agilent Cary 630 FTIR kit for product brochure, overviews, and application notes.
Spectroscopy & Chromatography . . . Learn More One-molecule Spectroscopy Swiss researchers demonstrated the simplest, smallest spectroscope ever: a single molecule absorbing a single photon. The experiment in quantum engineering was challenging, not only because the light needed to be at a compatible energy with the molecule, and with sufficient brightness, but also because the light had to be routed to the location of the molecule. Signs of Ancient Smoking Researchers determined that theresidue in a 1300-year-old Mayan flask was nicotine, and products of nicotine oxidation. A short Scientific Americanpodcast explains how the researchers combined gas chromatography, liquid chromatography, and mass spectroscopy to identify tobacco residue from inside the uncleaned container. Based on images, archeologists assumed that the Mayans smoked tobacco: now we have proof. Microscopy & Imaging . . . Learn More Chemical Imaging of Cells A new twist on nanospray desorption electrospray ionization (nano-DESI) with mass spectrometry lets researchers keep track of where molecules originate on the sample, with spatial resolution down to an area about 10 µm in diameter. Researchers can build chemical images of the surface, based on nano-DESI with resolution about an order of magnitude better than other online liquid extraction techniques. Imaging Whole Brains Faster By automating both the tissue sectioning and fluorescence imagingrequired for 3D whole-brain imaging, researchers hope to speed up the process and make it available to more users. The Serial Two-Photon Tomography system showed half-micron resolution with the deep penetration typical of two-photon excitation. The developers used the method for several mouse-brain imaging experiments.   Hiden Analytical Celebrates 30 Years Hiden Analytical LiquiPhysics Excellence Mettler-Toledo, Inc.

Learn More Sorting Carbon Nanoparticles It's simple to create a whole range of carbon nanoparticles, but trickier to sort the graphene from the fullerenes. The high surface activity that makes nanoparticles so interesting becomes a problem when trying to apply separation processes. Researchers recently showed that anion-exchange chromatography can divide carbon nanoparticles based on their negative charge, which corresponds to size and composition. The group is scaling up production now. Better Eye Diagnostics Better resolution from a confocal adaptive optics technique bringsindividual retina rods into focus, as well as cones. Previous instruments used adaptive optics to correct for astigmatism, but they couldn't see the smaller light-sensing cells. Higher-resolution images will aid ophthalmic clinicians, but image processing and interpretation remain as challenges. Metrology & Calibration . . . Learn More Nanothermal Analysis Tackles Hard Surfaces Nanoscale metrology on hard surfaces just acquired a new tool. The temperature-dependent properties of soft materials at scales below 100 nm can be revealed using nanoscale thermal analysis (nanoTA), an atomic force microscope-based technique. But stiff surfaces have not been easy to measure. A group of researchers has refined the technique using magnetic actuation to move the tip. Nanocrystallography by SEM Crystal phase information from tiny crystals is hard to obtain but has major effects on material properties. In March, a Journal of Microscopy paper will detail ways to obtain a roughly 10-fold improvement in the ability to measure the crystal structure of nanoparticles and extremely thin films, with only a slightly modified standard scanning electron microscope (SEM).   Ultrameter III Features Portable Lab-accurate Titrations Myron L Company Color HPLC Columns — Only Available Here!
