This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Antibiotics are powerful for fighting infection. But they could create a dangerous imbalance in the gut, where the eradication of harmful bacteria might make room for gut fungi to invade. To find out, researchers analyzed stool samples from 14 healthy participants. Samples were collected over 3 months following a 6-day course of antibiotics. While the bacterial community mostly rebounded over those 3 months, the fungal community shifted from one characterized largely by mutually beneficial interactions (red) to one fraught with competitive interactions (blue) with half of the bacterial-fungal interactions detected before the antibiotic treatment disappearing 3 months later. Metagenomics data revealed that certain bacteria normally help keep opportunistic fungal pathogens like Candida albicans in check. Understanding how could help researchers find ways to restore balance to the gut microbiome following drug treatment or during disease..."

"Two mosquito species in America have been engaged in a battle for dominance for the past 30 years: the native Aedes aegypti and the invasive Aedes albopictus -- also known as the Asian tiger mosquito The tiger mosquito has a distinct competitive advantage Male Aedes albopictus are really good at wooing female Aedes aegypti The resultant interspecies mating permanently sterilizes the female, effectively ending her reproductive future But Aedes aegypti are evolving the ability to resist the advances of Aedes albopictus Although this is good news for Aedes aegypti the outlook is darker for humans, as Aedes aegypti are key transmitters of diseases like Zika and dengue fever Researchers have now started to uncover the genetic changes tied to this resistance Uncovering the molecular correlates governing mosquito mating preferences could lead to better control strategies and might help prevent future outbreaks of disease Burford Reiskind, et al..."

This is a really fun and informative lesson that I do with my high school Programming/technology class to break up the monotony of beginner programming. However; this lesson can be used and applied in essentially any class and for many purposes, and to address many areas. One of the other really nice things about this lesson is that it can be extended to hit many points including physics, math, and advanced engineering.

Throughout the building period, I would present teams with a challenge (puzzle, build, etc…) and the first team to complete it would get a prize. It could be more modification time, extra materials, etc…)

The materials (including hot glue guns) can be purchased at Wal Mart or a similar store for around $20-25, if ordering through your district isn’t an option. With those purchases, it gives you a lot more materials than needed which can be used for additional similar projects.

Explore a NetLogo model of populations of rabbits, grass, and weeds. First, adjust the model to start with a different rabbit population size. Then adjust model variables, such as how fast the plants or weeds grow, to get more grass than weeds. Change the amount of energy the grass or weeds provide to the rabbits and the food preference. Use line graphs to monitor the effects of changes you make to the model, and determine which settings affect the proportion of grass to weeds when rabbits eat both.

Explore how populations change over time in a NetLogo model of sheep and grass. Experiment with the initial number of sheep, the sheep birthrate, the amount of energy sheep gain from the grass, and the rate at which the grass re-grows. Remove sheep that have a particular trait (better teeth) from the population, then watch what happens to the sheep teeth trait in the population as a whole. Consider conflicting selection pressures to make predictions about other instances of natural selection.

One of the many challenges facing the countries in the Asia-Pacific today is preparing their societies and governments for globalization and the information and communication revolution. Policy-makers, business executives, NGO activists, academics, and ordinary citizens are increasingly concerned with the need to make their societies competitive in the emergent information economy.

The e-ASEAN Task Force and the UNDP Asia Pacific Development Information Programme (UNDP-APDIP) share the belief that with enabling information and communication technologies (ICTs), countries can face the challenge of the information age. With ICTs they can leap forth to higher levels of social, economic and political development. We hope that in making this leap, policy and decision-makers, planners, researchers, development practitioners, opinion-makers, and others will find this series of e-primers on the information economy, society, and polity useful.

Elementary School Engineering Design Field Day
Read the Fine Print
Educational Use
Rating
0.0 stars

This unit provides the framework for conducting an “engineering design field day” that combines 6 hands-on engineering activities into a culminating school (or multi-school) competition. The activities are a mix of design and problem-solving projects inspired by real-world engineering challenges: kite making, sail cars, tall towers, strong towers and a ball and tools obstacle course. The assortment of events engage children who have varied interests and cover a range of disciplines such as aerospace, mechanical and civil engineering. An optional math test—for each of grades 1-6—is provided as an alternative activity to incorporate into the field day event. Of course, the 6 activities in this unit also are suitable to conduct as standalone activities that are unaffiliated with a big event.

This course explores the proper role of government in the regulation of the environment. It will help students develop the tools to estimate the costs and benefits of environmental regulations. These tools will be used to evaluate a series of current policy questions, including: Should air and water pollution regulations be tightened or loosened? What are the costs of climate change in the U.S. and abroad? Is there a “Race to the Bottom” in environmental regulation? What is “sustainable development”? How do environmental problems differ in developing countries? Are we running out of oil and other natural resources? Should we be more energy efficient? To gain real world experience, the course is scheduled to include a visit to the MIT cogeneration plant. We will also do an in-class simulation of an air pollution emissions market.
