Soil is the linchpin of the environment, where atmosphere, biosphere, and hydrosphere meet. Despite that, many students see soil as “just dirt” – a place to grow plants, but nothing more. Soil science educators are challenged with the task of helping students and the public recognize the critical importance of soil in the environment.
A collaborative project by soil science and earth science teachers at University of Nebraska-Lincoln, Oregon State University-Cascades, Colorado State University-Fort Collins, Trinity College, and University of Minnesota explored the development and dissemination of soil e-lessons. By harnessing technology, the instructors created learning tools that could reach beyond their classroom walls to teach other students and public audiences about soils as well.
The project, which is featured in the 2009 edition of the Journal of Natural Resources and Life Sciences Education (JNRLSE), aimed to develop and promote the use of online lessons to educate college students and the public about role of soil in addressing food, energy, and environmental issues. To engage learners, the developers focused on the inclusion of active learning strategies, interactive Flash animations, experiential learning activities, transfer problems, embedded questions, images, and text as primary instructional elements. All activities were contained in a web-based format to make them easy to use and share. Development of the e-lessons was supported by a National Science Foundation Course, Curriculum, and Laboratory Improvement Program Award.
The University of Nebraska-Lincoln’s “Plant and Soil Sciences eLibrary” showcases lessons developed for the program. It features activities on topics such as rocks and minerals, weathering processes, soil forming factors, processes of soil profile development, and soil taxonomy and geography. The lessons cover the fundamentals of why soils are what they are, and how they came to be that way. Developers believe these basic lessons will spark further interest in soil, and help learners recognize soil as an essential part of the environment.
The e-lessons can be readily accessed through the University of Nebraska’s Plant and Soil Sciences eLibrary, under the section entitled “Soil Genesis and Development” at: http://plantandsoil.unl.edu/croptechnology2005/soil_sci/

Today's educators are looking to the Journal of Natural Resources and Life Sciences Education, http://www.jnrlse.org, for the latest teaching techniques in the life sciences, natural resources, and agriculture. The journal is continuously updated online during the year and one hard copy is published in December by the American Society of Agronomy.
The American Society of Agronomy (ASA) www.agronomy.org, is a scientific society helping its 8,000+ members advance the disciplines and practices of agronomy by supporting professional growth and science policy initiatives, and by providing quality, research-based publications and a variety of member services.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
