Greenhouse gas measurements along polar ice cores provide important insight into the former composition of the atmosphere, its natural variations, and the responses to fast climatic changes in the past. We present high-resolution nitrous oxide (N2O)…
-
The response of nitrous oxide (N2O) emission rates and β-proteobacterial ammonia-oxidizing (AOB) communities to manipulations of temperature, soil moisture and nitrogenous fertilizer concentration were studied for 1620 weeks in a multifactorial…

Nitrogen (N) and phosphorus (P) availability limit plant growth in most terrestrial ecosystems. This review examines how variation in the relative availability of N and P, as reflected by N : P ratios of plant biomass, influences vegetation…
-
Nitrogen and phosphorus supply influences the rate of litter decomposition and nutrient dynamics during decomposition. Besides the total amount of N and P available to decomposers, their relative supply (N:P ratio) might be important, e.g. through…

The proto-oncogene c-myc governs the expression of a number of genes targeting cell growth and apoptosis, and its expression levels are distorted in many cancer forms. The current investigation presents an analysis by proteolysis, circular…

The combination of branched DNA molecules and 'sticky' ends creates a powerful molecular assembly kit for structural DNA nanotechnology. Polyhedra, complex topological objects, a nanomechanical device and two-dimensional arrays with. programmable…
-
The interface between nanosystems and biosystems is emerging as one of the broadest and most dynamic areas of science and technology, bringing together biology, chemistry, physics, biotechnology, medicine, and many areas of engineering. The…

First Paragraph... Biogenic minerals HN1 are generally those formed in the presence of biological cells (mainly bacteria; see the figure) and structures outside cells (1). These minerals, which come in a variety of types and shapes, are often small…
-
Methods based on self-assembly, self-organization, and forced shape transformations to form synthetic or semisynthetic enclosed lipid bilayer structures with several properties similar to biological nanocompartments are reviewed. The procedures…
