Source: Supplied projects for Exclusively online Formal Verification is the process of rigorously analyzing software to detect flaws that make programs vulnerable to exploitation. Performing this analysis requires highly skilled engineers with extensive training and experience. This makes the verification process costly and relatively slow. The Defense Advanced Research Projects Agency (DARPA) Crowd Sourced Formal Verification (CSFV) program is interested in improving and advancing the current processes of formal verification by significantly increasing the number of people working on formal verification projects at any given time through crowd-sourcing. CSFV augments the intensive work done by formal verification experts by greatly decreasing the skill required to do formal verification. Much of the work required in the process of formal verification can be automated.

NH Field Investigation Models Using Field Investigations to Model Scientific Inquiry State and national science standards emphasize the importance of inquiry and problem-solving for today’s students. Field investigations offer rich opportunities for students to practice inquiry in engaging and authentic ways. Key steps in field investigations mirror the inquiry process. They are posing research questions, planning and conducting investigations, using evidence to describe findings, communicating research findings to target audiences, and asking new research questions based on findings.

Science of Cooking • Explore the science behind food and cooking with recipes, activities, and Webcasts.PreviousNext 99 Best Online College Resources on Open Courseware & MOOCs With the increasing popularity of online education has come a profusion of Massively Open Online Courses (MOOCs), Open Courseware (OCW), Open Educational Resources (OER), and other general educational resources that can be accessed online. MOOCs are usually full courses with actual assignments and a similar structure to a traditional college class, whereas OCW and OER are simply resources, such as textbooks, class rubrics, and other corollary materials that students can use to guide their independent learning. This collection isn’t intended as an ordered ranking comparing the quality of these sites, but a repository of great resources for anyone who wants to learn more about MOOCs and OCW. Many companies have set up platforms that anyone can use to create and promote MOOCs, and as the MOOC format gets more popular, there will doubtlessly be heavy competition to create the best course creation and hosting service.

Gene-Environment Interaction Description Nearly all diseases result from a complex interaction between an individual’s genetic make-up and the environmental agents that he or she is exposed to. Examples of environmental agents: Mold Ozone Pesticides Air pollution Cleaning solutions Dust mites Some foods and medications Subtle differences in genetic factors cause people to respond differently when exposed to the same environmental agent. As a result, some possess a low risk for developing a disease through an environmental insult, while others are much more vulnerable.

Microscope Imaging Station. Neurons: A Fish-Eye View of the Brain Speed-dating neurons make connections Researchers in the Smith lab have also been able to watch the development of single neurons as they grow and connect to each other to complete the optical system. What they’ve seen helps explain how the brain's enormous complexity emerges. It now appears that brain organization happens in stages. As a developing neuron grows, it sends out tiny exploratory branches called filopodia. These projections search for partners in an effort to make connections and form synapses. Nutrition, Metabolism, and Temperature Regulation We are often more concerned with the taste of food than with its nutritional value when choosing from a menu or when selecting food to prepare. Knowing about nutrition is important, however, because food provides us with energy and the building blocks necessary to synthesize new molecules. What happens if we don't obtain enough vitamins, or if we eat too much sugar and fats? Health claims about foods and food supplements bombard us every day.
