New Republic: At a Thursday budget hearing in the Senate Space, Science, and Competitiveness subcommittee, Ted Cruz--long known as an informed, astute scientific observer, specifically regarding climate--insisted that NASA "get back to the hard sciences". In his mind, that means the agency should focus on more space exploration and less Earth science. [T]here are a lot of people studying Texas soil, youve got a whole Department of Agriculture that spends a lot of time and energy studying the soil in Texas and...
Scientists precisely control gold-coated nanoparticles with lasers
2015-03-13 21:30:19| Extremetech
Among the many kinds of materials used to create new nano- and micro- technology, gold has emerged as the premier element primarily because of its unique opto-electronic properties. Researchers from Munich have recently used this 'plasmonic gold' to build what they are calling a microscale elevator, although the implications for significantly more far-reaching.

Nature World: It has long been suggested that our impact on the planet is so substantial that it grants its own new geological epoch - known as the Anthropocene. While the beginning of this new era has been heatedly debated, one group of scientists believes it has finally pinpointed the exact date of when humans began to dominate the Earth. The year was 1610, when the effects of the collision between the New and Old Worlds, which occurred a century earlier, were first felt around the globe. That is, there was...
Where have all the soil scientists gone?
2015-03-11 21:05:00| Corn & Soybean Digest
I have been an educator of soils at the University of Minnesota Extension for 18 years. I have watched soil scientist retire, leave to other positions or pass away. Due to tight budgets or changes in priorities, many are not replaced. So please help me cultivate the next generation of soil scientists. There are websites with creative and scientific resources for teaching soils. Give it a try. Remember: Soil is not a dirty word! read more
