NMR Investigates Natural Antibiotics
Solid-state NMR spectroscopy can provide researchers with a detailed image of antimicrobial peptides and how they sit in the cell membrane. At the annual Biophysical Society meeting in Baltimore, researchers reported investigating the peptides produced by the immune system in most animals, including frog's skins and human lungs.

FRET-ing over Mad Cow
Take the first look at unfolded yeast prions which form the compound amyloid, a fibrous protein aggregate associated with neurodegenerative diseases such as Alzheimer's disease and variant Creutzfeldt-Jacob disease (the human version of Mad Cow Disease). It was obtained by researchers using a combination of single-molecule fluorescence resonance energy transfer, fluorescence correlation spectroscopy, and single molecule fluorescence coincidence.

Modern Liquid Chromatography
Modern liquid chromatography captivated a standing-room-only technical session at Pittcon, held in March. LCGC North America reports on the papers from this session. High performance liquid chromatography talks included "New 'Fused-Core' Particles for Very Fast HPLC Separations" (by using very small particles) and "Temperature Selectivity in RP-HPLC."

Hot and Cold Chromatography Software
Laura 3, a chromatography data collection and analysis package originally designed for 'hot' radiochromatography, has been extended to work with 'cold', non-radiolabelled applications. Laura interfaces with many popular high performance liquid chromatography and thin-layer chromatography systems, and more than 80 pumps, autosamplers, column ovens, detectors, and other support devices.

Single Atom Spin Microscopy
Using a scanning tunnelling microscope to look at two adjacent cobalt atoms adsorbed at a copper surface, German scientists measured how their spins interact, depending on the distance between them. This could be used to probe the quantum nature of magnetic phenomena and to explore the physical limits of magnetic data storage.

Multispectral Imaging Gets the Goods
By performing both conventional and fluorescent imaging in the visible, UV, and IR, archeologists at Ohio State University can decipher clues about dyes and pigments used in ancient textiles, say the researchers. Art museums have used multispectral imaging to investigate paintings in the past, as have forensic crime investigators.

It Lives!
When a disease-causing organism is found in the air, the next question is whether it is viable — in other words, can it infect people? Usually, if the detected sample cannot be grown in culture, we assume that it isn't viable. But culturability is different from viability, shows new research.

Cellular MEMS Measures Change
An instrument that measures the mechanical properties of a living cell has been developed by researchers at the National Institute of Standards and Technology (NIST). The microelectromechanical system (MEMS) stretches cells. Many diseases change the mechanical flexibility of cells — for example, malaria increases the stiffness and stickiness of red blood cells.

Konica Minolta, Sensing Americas, Inc
Spectrophotometer
Two features distinguish the CM-3600d (from Konica Minolta Sensing Americas, Inc.) from most other benchtop instruments available. First, it performs faster and more accurate measurements of samples with gloss differences. Second, the CM-3600d instrument offers instantaneous numerical ultraviolet adjustment for samples which contain a UV-absorbing light component, such as fluorescing dyes, pigments, and optical brighteners.

Calibrating Instruments with Celestial Bodies NASA scientists asked for the sun and moon to calibrate their instruments aboard the STEREO-B spacecraft — and got them. To measure the dark current of the four extreme-UV cameras, they imaged the moon as it passed between the spacecraft and the sun. The images were taken from space, because the moon appears much smaller from the spacecraft than from Earth's surface.
