I present a learning cycle that explores different biotechnologies using the process of in situ hybridization as a platform. Students are presented with a cyclopic lamb and must use biotechnology to discover the mechanism behind the deformity. Through this activity, students learn about signal transduction and discover the processes of polymerase chain reaction, gel electrophoresis, restriction enzyme digests and ligations, cloning, and transformation. Students also discover the nature of scientific inquiry and practice hypothetico- deductive reasoning. Copyright © 2010 by National Association of Biology Teachers. Source

Laboratory experiences are a vital component within science education. This paper is a report on the findings of a study conducted on undergraduate level laboratory science courses. A causal-comparative quantitative study was conducted with 150 learners enrolled at a 2-year community college, to determine the effects of simulation laboratory experiments on Higher-Order Learning, Critical Thinking Skills, and Cognitive Load. The treatment population used simulated experiments, while the non-treatment sections performed traditional experiments. Comparisons were made using the Revised Two-Factor Study Process survey, Motivated Strategies for Learning Questionnaire, and the Scientific Attitude Inventory survey, using a Repeated Measures ANOVA test for treatment or nontreatment. © Springer International Publishing Switzerland 2015.

In 1965, Gordon Moore predicted that the number of transistors on a chip would double every year for the next 10 years. Moore's law is still in effect today, with more than a billion transistors able to fit on a chip as of 2010. This article revisits Moore's law and the rise of microelectronics. © 2015 IEEE. Source

The increasing abundance of retrofit solutions for lighting, heating and other key building systems is allowing customers to benefit from increased energy efficiency – but without incurring the sometimes intimidating costs associated with entirely new installations, says Energys Group Managing Director Kevin Cox. The motivation for businesses – be they large, medium or small – to investigate measures designed to reduce energy consumption is now truly manifold. Not only is there a regulatory impulse from both national governments and European institutions, there is also a moral dimension that encourages companies to do all they can to reduce their carbon footprints as the impact of climate change becomes increasingly apparent. Then there is the potential cost-saving that can result from next generation systems – a reduction that can be in excess of 60% in the case of the latest LED lighting technologies. But while major corporates may be in a position to undertake dramatic overhauls of their technological infrastructures, the same cannot always be said of SMEs. Indeed, even some larger companies can struggle to make the case to shareholders in what remains an unpredictable economic period. In these instances, the argument for exploring the opportunities presented by retrofitting – whereby new technologies are applied to older, existing systems – becomes highly persuasive. Not only can they allow businesses to enjoy reduced energy consumption across lighting, heating and other core building systems, they can also deliver these benefits with far lower installation costs and a fraction of the disruption that may be encountered with entirely new fitouts. In addition, there are also a number of attractive financing options that can help businesses to achieve this transition. Here at Energys we have consistently targeted primary sources of energy waste to devise solutions that allow businesses to achieve financial ‘easy wins’. As their high profile in the energy management media would suggest, retrofit energy-efficient lighting systems can deliver dramatic results; for example, we offer a plug-in T5 adapter, Save It Easy, that allows replacement of old-style fluorescent lamps with more efficient equivalents in the existing light fittings. Impressively, energy savings resulting from such retrofits can be in the region of 65% – and then there are the proven long-term benefits for employee health and performance to bear in mind. But our findings suggest that fewer businesses have contemplated retrofits affecting other building systems such as heating and general power supply. A technology such as boiler optimisation – which allows the efficiency of a boiler to be improved without any detrimental effect on the temperature of the building – can be installed in just a few hours with a minimum of disruption. But the long-term knock-on effect can be substantial, with typical energy savings of 15-30% per year and payback on the entire project achieved in no more than 24 months. Similarly, there is now an abundance of solutions aimed at overall power optimisation. These typically involve devices that are situated between the electricity supply and lighting distribution board, with the effect of reducing voltage, improving power factor and smoothing harmonics. Once again, the result is reduced energy consumption, with savings in the region of 40% by no means uncommon. Businesses may also be advised to instigate energy-saving sound surveys to remove compressed air and other gas leaks, as well as invest in reusable insulation covers for plant room equipment so that no heat is wasted. It is now common for businesses to seek to implement multiple such measures simultaneously. The same is true of other sectors, such as education, where Energys Group also remains highly active. For example, a recent retrofit upgrade at Hackney Community College (HCC) in East London entailed the conversion of 4,900 lamps to LED, as well as the implementation of boiler optimisation controls and specialist insulation. The switch to LED alone is expected to generate an annual energy saving of £70,000, whilst the overall upgrade is on course to pay for itself in just over 2.5 years. In the case of HCC, the college successfully applied to the Salix Finance Scheme, which continues to help many public sector organisations make the change. But there are also several programmes aimed at helping commercial facilities to implement energy efficient technologies, including leasing schemes, loans provided by Siemens Financial Services at commercial rates of interest, and Government-backed Carbon Trust loans for SMEs in Wales and Northern Ireland. Applying for funding under these and other schemes can be difficult and time-consuming, but the good news is that many specialists (including Energys) are now more than happy to assist with the application process. Once again, then, it is evident that tapping the services of a collaborator with a proven and distinguished track-record in energy efficiency can make all the difference to the fruition of a project. Far from being limited to the conversion of lighting systems, today’s energy saving initiatives can encompass heating, power optimisation, control and other core building systems. While sizeable investments may be attached to such upgrades, retrofitting provides the best possible way for businesses to benefit from the latest technologies without incurring all the costs of ‘from scratch’ installations.
Home > Press > COD Grad Begins Postdoctoral Fellow at Harvard University: Marsela Jorgolli's Passion for Physics Has Led to a Decade of Academic Research That Continues at Harvard University as a Postdoctoral Fellow Abstract: Having successfully defended her Ph.D. in Physics at Harvard this past May, the former College of DuPage student is working as a member of the university's Park Research Group, led by renowned Professor Hongkun Park. The team focuses on researching nanometer-sized materials -- such as nano-diamonds, which are not visible to the naked eye -- in hopes of developing and building devices that work with cell networks. These devices eventually could be implemented in multiple ways, such as multiplexed brain functional sensing and high-throughput pharmaceutical screening. "Being at the forefront of this research is very exciting," Jorgolli said. "I love contributing to the development of new tools that will better our society, tools that were once thought of as impossible." Jorgolli's team's accomplishments are many, including their first measurement of cellular membrane potential changes using nano-diamonds and the submission of several patents based upon their development of new technologies. In 2014, Jorgolli was selected to attend the GapSummit at the University of Cambridge in the United Kingdom. It was the first international and inter-generational gathering that focused on inspiring and engaging the next generation of biotechnology leaders, and she was one of only 100 people worldwide invited to participate. Click here to watch a video of Jorgolli interviewed during the summit. Her success is a reflection of the difficult decision her parents made to move their family from Albania to Villa Park, Ill., in order for Jorgolli -- valedictorian of her high school class -- to pursue a career in physics and chemistry. "We moved to the U.S. in late July, and I was thinking about applying to Northwestern," she said. "But because it was so late, their admissions period had already closed." Jorgolli enrolled at College of DuPage and embarked on what would become a stellar academic career that resulted in numerous honors, including being named to the All USA Community College Academic First Team and receiving the prestigious Barry M. Goldwater Scholarship. She was the first COD student to receive the latter, a premier national honor for students pursuing careers in mathematics, science and engineering. Jorgolli also was selected for the inaugural meeting of the Center for Gravitational Wave Astronomy (CWGA) at the University of Texas at Brownsville and was the only community college representative, as well as the only freshman, selected to attend opening celebrations for the NASA University Research Center at UT. Her mentor, College of DuPage Physics Professor Tom Carter, was immediately impressed by her abilities. "Marsela was probably the most motivated and talented student I've ever had," he said. "From the moment she joined my class, she was eager to learn and was always asking questions. It was clear that she would go far with her career." After College of DuPage, Jorgolli transferred to the University of Chicago and found the transition challenging. "I had taken all of the science courses I could at College of DuPage so I could start taking classes at the junior level. It was not easy, but I learned so much," she said. "During my first week in Biophysics, I was attracted to the quantitative tools of studying nature and physics as well as how physics principles are used in biology." She earned her bachelor's degree in Physics and immediately applied to doctoral programs, deciding that Harvard was the best fit and an excellent place to spend the next phase of her academic life. After initially taking classes, she became a member of Park's research group. "We developed nanotechnology tools to study complex biological systems," she said. "Our focus was to develop large-scale, solid-state devices that would be used to interface with neurological networks that stimulate activity." As Jorgolli begins work as a postdoctoral fellow, her long-term goal is to continue in research that will lead to the development of complex, integrated, nano- and micro-scale platforms. "It's important to determine a better way to see how the brain works, and our work can lead to the development of new drugs to fight brain disease," she said. "The work is very satisfying, and we've already developed the first generation of devices of single cells in networks. "When I came to the U.S., I wanted to attend a great university. I didn't come here for a two-year community college, but College of DuPage ended up as the best route for me. COD gave me the resources and opportunities to excel in my academics and my career."
