Mass Spectrometry IDs Dinosaur Protein
A mass spectrometry technique provided the sequence of a 68 million-year-old protein and thus identified it. The protein was recovered from the bone of a T. rex. When a researcher demineralized the ancient bone, she found that a collagen matrix remained, according to a report in the April 13 issue of Science.

Making Hay While the Sun Shines
Researchers used 2D electronic spectroscopy, which allows one to follow the flow of light-induced excitation energy through molecular complexes with femtosecond temporal resolution, to unravel the mystery of how photosynthesis can be so efficient. Green plants and cyanobacteria convert sunlight into chemical energy with nearly 100% efficiency.

New Car Smell Nontoxic
Feel free to breathe that new car smell: those volatile organic compounds may not be so bad after all. Samples from new cars were analyzed by a gas chromatography-mass spectrometry system equipped with a carbon dioxide oven cooling system, a HP-5 capillary column, a flame-ionization-detector (FID), and a mass selective detector. The VOCs showed no detectable toxicity.

Imaging MS
Three microscopic imaging techniques: sum frequency generation, two-photon-excitation fluorescence, and coherent anti-Stokes Raman scattering can be used simultaneously to learn about the molecular mechanisms of multiple sclerosis. The combined imaging method shows how MS causes an overproduction of astroglial filaments and degrades the myelin sheaths over nerves.

Chem-Analysis for Pharmaceuticals
A near-infrared chemical imaging system won an Innovation Award, a new award instituted by the technical journals PROCESS, PharmaTEC, and Schüttgut. The SyNIRgi system won in the Materials Analysis and Characterization section. Chemical imaging is being used increasingly by the pharmaceutical industry. The system was introduced this year at Pittcon.

Untangling Metallic Messes
How do dissolved metal ions interact in solution? It's a question that can affect how we clean up toxic messes ranging from industrial to nuclear waste. When researchers applied X-ray scattering techniques to the problem, they were able to see ion structures in solution as well as reveal interactions with other ions.

Bacteria Tip the Balance
A mosquito-sized biosensor can detect amazingly small amounts of disease-causing E. coli bacteria in food in a single-step process taking only minutes. The sensor incorporates a tiny vibrating cantilever, coated with antibodies for E. coli, anthrax, or specific proteins. Antigens that bind to the antibody alter the frequency of the vibration.
