This set of Review and Commentary articles comes on the heels of a recent collaboration between Cell Press and the reality competition "Top Chef" and covers the latest research on such topics as the biology underlying molecular gastronomy, our perception of food, the future of growing crops, how to tackle obesity, and the interplay between diet and the circadian clock. "The multifaceted ways in which food factors into biological, social, and political issues seem to only be getting more complex," says Cell Scientific Editor Joo Monteiro. "This special issue, 'The Biology of Food,' explores the science behind food, nutrition, and metabolism. Like any great menu, it offers plenty of options that we hope will first tantalize and then satisfy each individual's palate." The science of molecular gastronomy "It is a sad reflection on our civilization that while we can and do measure the temperature in the atmosphere of Venus, we do not know what goes on inside our souffls," remarked Nicolas Kurti in 1969.

In biology, materials science and the energy sciences, structural information provides important insights into the understanding of matter. The link between a structure and its properties can suggest new avenues for designed improvements of synthetic materials or provide new fundamental insights in biology and medicine at the molecular level. During standard X-ray solution scattering experiments, molecules tumble around during X-ray exposures, resulting in an angularly isotropic diffraction pattern because of the full orientational averaging of the molecules that scatter X-rays. When X-ray snapshots are collected at timescales shorter than a few nanoseconds, such that molecules are virtually frozen in space and time during the scattering experiment, X-ray diffraction patterns are obtained that are no longer angularly isotropic. These measurements, called fluctuation X-ray scattering, are typically performed on an X-ray free electron laser or on an ultra-bright synchrotron and can provide fundamental insights into the structure of biological molecules, engineered nanoparticles or energy-related mesoscopic materials not attainable via standard scattering methods. A group of scientists from the Lawrence Berkeley National Laboratory recently presented an intuitive view of the nature of fluctuation X-ray scattering data and their properties. The scientists have shown that fluctuation scattering is a natural extension of traditional small-angle … Continue reading →
