Research That Is Unraveling the Puzzle of Obesity Showcased in January Issue of AACC’s Journal Clinical Chemistry

Laboratory medicine experts are using genomics, metabolomics, and other cutting-edge clinical testing methods to advance the understanding of obesity. A special issue of AACC’s journal Clinical Chemistry, “Obesity: Innovative Approaches to Overcome Obstacles,” highlights the latest innovations in the field that could lead to more effective public health policies to curb this epidemic.

Researchers Discover Higher Environmental Impact From Cookstove Emissions

Millions of Asian families use cookstoves and often fuel them with cheap biofuels to prepare food. But the smoke emitted from these cookstoves has a definite, detrimental environmental impact, particularly in India. New research from Washington University in St. Louis offers a clearer picture of the topic’s true scope.

Silver Nanoparticles Take Spectroscopy to New Dimension

As medicine and pharmacology investigate nanoscale processes, it has become increasingly important to identify and characterize different molecules. Raman spectroscopy, which leverages the scattering of laser light to identify molecules, has a limited capacity to detect molecules in diluted samples because of low signal yield, but researchers in India have improved molecular detection at low concentration levels by arranging silver nanoparticles on silicon nanowires. They describe their work in this week’s Journal of Applied Physics.

Locating the Precise Reaction Path: Methane Dissociation on Platinum

So far, the search for catalysts even better than transition metals has been largely based on trial and error, and on the assumption that catalyzed reactions take place on step edges and other atomic defect sites of the metal crystals. An international research team has combined experiments using advanced infrared techniques with quantum theory to explore methane dissociation reactions in minute detail. They report their findings this week in The Journal of Chemical Physics.

Research shows that missense mutations in a cluster of just five codons in the NF1 gene are an important risk factor for severe symptoms of the genetic disease neurofibromatosis type 1. Such information is vital to help guide clinical management and genetic counseling in this complex disease.

Meet the Tiny Machines in Cells that Massacre Viruses

When viruses infect the body’s cells, those cells face a difficult problem. How can they destroy viruses without harming themselves? Scientists at University of Utah Health have found an answer by visualizing a tiny cellular machine that chops the viruses’ genetic material into bits.

Molecular Mapping Made Easy

Every day, every inch of skin on your body comes into contact with thousands of molecules — from food, cosmetics, sweat, the microbes that call your skin home. Now researchers can create interactive 3D maps that show where each molecule lingers on your body, thanks to a new method developed by University of California San Diego and European Molecular Biology Laboratory (EMBL) researchers.
