The Producers\u27 Stake in the Bioeconomy: A Survey of Oklahoma Producers\u27 Knowledge and Willingness to Grow Dedicated Biofuel Crops

The study reported here found that producers were familiar with the biofuel industry through mass media channels and were willing to convert cropland to energy crops. Producers were motivated by patriotic reasons, but overall profitability was the greater motive for converting cropland to dedicated biofuel crops such as switchgrass. Barriers to energy crop production were a lack of markets (biorefineries) and information about biofuel crop production. It is recommended that an educational campaign regarding biofuel crop production best practices, especially cellulosic crops (switchgrass) and marketing, be implemented. A statewide leadership campaign to attract biorefineries to the state is also recommended

Using Wii Technology and Experiential Learning to Teach Newtonian Mechanics to Rural Middle School Students

This study looked at the effects of an experiential learning activity using the accelerometer in the Wii Remote to teach basic concepts of Newtonian mechanics, e.g., acceleration, to middle school students in a rural school district. A major prerequisite for students at the mid-level in biosystems engineering programs is that they have a good knowledge of basic science, including physics. Education in these concepts must begin before college, such as at the middle school level. Improvements in science education are vitally necessary to achieve essential learning outcomes for middle school students in the U.S. and to prepare these students for college and STEM careers. The experiential learning activity evaluated in this study used hands-on experiments involving Wii Remotes in conjunction with a classroom lesson to teach basic concepts of Newtonian mechanics: acceleration, gravity, force, velocity, friction, speed, and motion. This activity used readily available equipment and was integrated into the classroom curriculum so that it has been possible to continue the activity every year without further support from the program that sponsored this study. The specific objective of this study was to evaluate the efficacy of this experiential learning activity with regard to learning outcomes and interest generated in science and engineering. Ninety-two percent (92%) of the students improved their knowledge from pre-test to post-test during the activity. When the students were surveyed about the activity, the kinesthetic/hands-on aspects of the project were the parts they liked most. Fifty-four percent (54%) of the students also indicated that the activity made them more interested in science and engineering. The positive outcomes from the activity combined with the readily available equipment make similar activities an excellent option for biosystems and agricultural engineering departments looking for outreach opportunities at the middle school level. This study showed that experiential learning, in middle school science classes, is significant in increasing students‘ knowledge of acceleration and interest in science and engineering

Apps —An Innovative Way to Share Extension Knowledge

Extension professionals across the country are continuously seeking innovative ways to reach clientele and to disseminate timely, educational information. A new avenue to reach clientele includes the use of smartphone apps. The Machinery Sizing app, which was developed to ease the estimation of tractor horsepower to implement sizing for Extension clientele anytime, anywhere, is explained as a key example for Extension professionals to utilize apps in disseminating information to clientele. There are many benefits to using apps, including information availability wherever Internet service is available on the smartphone, ease of computations of equations, and automatic updates being sent to users

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder
