Scientists from the University of Minnesota demonstrated yields of corn and soybeans were only minimally reduced when organic production practices were utilized as compared with conventional production practices. After factoring in production costs, net returns between the two production strategies were equivalent.
More than 80% of corn and soybeans produced in the United States is grown in the Midwest, the vast majority with conventional production practices in a corn-soybean rotation requiring annual synthetic fertilizer and pesticide application. This corn-soybean rotation is practiced on over 100 million acres.
Organic production practices, in compliance with standards defined by the United States Department of Agricultures National Organic Program (NOP), offer an alternative production system to conventional practices. The study of the influence of rotation length on yield of corn and soybean when grown utilizing organic and conventional production practices is published in the March-April, 2003 issue of Agronomy Journal, a publication of the American Society of Agronomy.

Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix. Until today, the question about the exact anatomical origin of these fibroblasts has not been answered. In order to find potential ways of influencing the scarring process, the team of Dr. Yuval Rinkevich, Group Leader for Regenerative Biology at the Institute of Lung Biology and Disease at Helmholtz Zentrum München, aimed to finally find an answer. As it was already known that all scars derive from a fibroblast lineage expressing the Engrailed-1 gene - a lineage not only present in skin, but also in fascia - the researchers intentionally tried to understand whether or not fascia might be the origin of fibroblasts.

Research from a leading international expert on the health of the Great Lakes suggests that the growing intensity and scale of pollution from plastics poses serious risks to human health and will continue to have profound consequences on the ecosystem.

Conventional light microscopes cannot distinguish structures when they are separated by a distance smaller than, roughly, the wavelength of light. Superresolution microscopy, developed since the 1980s, lifts this limitation, using fluorescent moieties. Scientists at the Max Planck Institute for Polymer Research have now discovered that graphene nano-molecules can be used to improve this microscopy technique. These graphene nano-molecules offer a number of substantial advantages over the materials previously used, making superresolution microscopy even more versatile.
Microscopy is an important investigation method, in physics, biology, medicine, and many other sciences. However, it has one disadvantage: its resolution is...
