A quick green screen for biorefinery enzymes

Wheat harvest

Cellulose and chitin are the most abundant polymers on Earth and their potential is vast for the biofuel industry. Cellulose is the major component of plant cell walls and its degradation into sugars is at the core of biofuels production. Chitin forms much of the shells of crustaceans, exoskeletons of insects and even butterfly wings… Read more »

Blood – Crystal (Crystl) from Bloomington, USA

Written by Dr Ivana Samarzija, University of Zagreb, Croatia Epigenetic processes have been unequivocally linked to cancer and other complex diseases. DNA methylation, a major epigenetic mechanism, is perturbed in cancer tissue in the way that global hypomethylation appears at the same time as hypermethylation at gene promoters. In addition to epigenetic studies on tumor… Read more »

Is cancer preventable? The role of diet and obesity

Applecells_2014_all-green_small1

Cancer is a metabolic disease. So asserts a growing body of evidence, supported by twin pillars. On one hand is strong data from population studies showing that those with metabolic disorders, such as obesity and diabetes, have altered risks of specific types of cancer. Elio Riboli, Director of the School of Public Health at Imperial… Read more »
