"The aphid -- one of the most common crop pests in the world -- has a weakness that scientists have now learned to exploit. When attacked by predators, the bugs release a pheromone to tell fellow insects to scatter. Biologists have proposed spraying these alarm pheromones directly on crops to prevent pest damage, but synthesis is costly. With the advent of genetic engineering, though, the cheaper option is to modify crops to produce the deterrents themselves. In 2015, biologists at Rothamsted Research, an agricultural research station in the UK, reported the first engineering feat of this kind in wheat. To make wheat release insect pheromones, the group inserted a gene from the peppermint plant, which allows plants to produce the appropriate chemical. Then, they tested whether the altered plants’ volatile compounds were capable of repelling the pests..."

"Animal health is of utmost importance in the production of milk, meat, and other animal products. Although vitamin supplements can help ensure livestock remain as healthy as possible, they are often expensive, driving up the cost of production. To help reduce these costs, a team of researchers set out to better understand how the essential vitamins B and K₂ are produced by microbes in the gastrointestinal tracts of ruminants, which are animals with complex digestive tracts composed of multiple distinct compartments to help them break down their plant-based diets. The team used genetic data from previous studies to identify 1,135,807 genes and 2366 full genomes involved in B or K₂ vitamin biosynthesis in the gastrointestinal tracts of seven ruminant species. They also found that most of this biosynthesis took place in the stomach compartments rather than other regions and that a high-grain diet enhanced most vitamin biosynthesis but inhibited cobalamin synthesis..."

In a 21st century globally-competitive society, agriculture is rapidly progressing and incorporating more innovative STEM practices (Science, Technology, Engineering and Mathematics). A number of agriculture advances incorporate genetics, which is an important unit in seventh-grade science. The lesson exposes students to a real-life application of genetics and technology to improve agriculture production and profit. The lesson specifically addresses bioengineering, biotechnology and selective breeding. Students use the technique of selective breeding in a class competition to make the best and most profitable grapes to sell to local industries. In doing so, they will learn about progressive agriculture science and technology, while covering the seventh-grade science genetics standards.

"The gilthead sea bream is one of the most important fish farmed in the Mediterranean. Selecting for economically valuable genetic traits has helped improve bream farming efficiency. But little is known about the role played by intestinal microbes in selective breeding practices. To find out, researchers examined how genetic selection for different growth rates and diet affect intestinal bacteria in the gilthead sea bream. Bream were divided into three groups according to genetically selected growth rate: slow, intermediate, and fast, and were fed a plant-based diet, a sustainable alternative for the normally carnivorous gilthead sea bream. The plant-based diet significantly changed the microbial makeup of the slow- and intermediate-growth groups, with a much weaker effect observed for the fast-growth group. And when exposed to an intestinal parasite common to the gilthead sea bream, the fast-growth group showed significantly lower parasite intensity and abundance than the slow-growth group..."

"Growing evidence suggests a link between the gut microbiome and physiological processes, including the immune response and neurological function. But the connection between the gut microbiome and complex diseases remains largely unexplored. A new study suggests that, at least among East Asian populations, distinct microbiome features could give rise to certain diseases. Researchers performed a microbiome genome-wide association study using samples from 1,475 Chinese participants. Their goal was to identify genetic variants among the participants associated with the gut microbiome. According to their findings, certain bacteria could be linked to the risk of certain diseases. For example, developing an irregular heartbeat is associated with an increased abundance of Burkholderiales and Alcaligenaceae, and decreased abundance of Lachnobacterium, Bacteroides coprophilus and Barnesiellaceae. And microbiome features could be clustered by disease, including different cancers, Alzheimer’s disease, and hepatitis..."

What factors lead to a natural disaster? What causes a famine? Why do cities flood? According to a recent article in The Atlantic, Houston's flooding during the 2017 Hurricane Harvey was primarily caused by impervious pavement which prevents the absorption of water into the land. This example illustrates how nature and society are interlinked, which is the main focus of Geography 30, Penn State's introductory course to nature-society geography. In addition to examining the linkages between human development and natural hazards, this course will also explore human society's connection to food systems, climate change, urbanization and biodiversity. The course will also cover topics of ethics and decision making in order to help students evaluate the tradeoffs of these interconnections.

Latin America covers part of North America, South America, and the West Indies. It stretches from lifeless Atacama desert to rugged highlands and Alpine glaciers of the Andes mountains. The fertile plains of the Pampas are one of the world's richest agricultural regions. The Amazon Basin is the largest and wettest lowland in the world. Culturally, Latin America is a great mixture of European, indigenous and African cultures.

In this course, we will examine the peoples and places of Latin America from a geographical perspective. We will explore the geographical dimensions of economic, cultural, political, and physical forces influencing Latin America as a region. We will have a mixture of thematic and regional approaches to study the concepts and look into various physical and historical processes that have shaped dynamic and diverse cultural landscapes. We will study contemporary environmental and developmental issues, trends in migration, agricultural change, and globalization to understand Latin America's position in the global economy.

Students are taken to a former plantation along a tidal river near Charleston, SC. The students are then shown how to sample and describe soils using an push-auger sampler, similar to those used in industry. After the demonstration, the students are taken to various locations on the plantation, including upland areas, wetlands, former agricultural areas, lowlands, and tidal marshes, to sample and make field descriptions of the various soils encountered. Students describe depths to horizons, soil color using Munsell Color Charts, soil texture, and any other pertinent properties. Students then prepare a formal technical write-up on the soils, their distribution, and how their sampling results compare to published soil data for the area.
