"With the world’s population expected to grow to over 9 billion by 2050, food is a major concern. Much of our increased food needs could be met by improving the yield of agricultural crops. A recent study examined one aspect of plant health: the plant microbiome, which plays a critical role in host health and productivity. Researchers focused on oilseed rape (OSR), the third most cultivated crop in the UK and a major source of vegetable oil. Field experiments have indicated that OSR yield declines proportionally with how often it is grown in rotation and while this has been associated with changes to the rhizosphere microbiome, it is unknown which microbes negatively affect plant yield. Comparing rhizosphere soil and bulk soil samples from 37 farms across the UK, they found that protists, bacteria, and fungi were influenced differently. Fungi were more widely influenced by the rotation frequency, but specific bacteria and protist species were also affected..."

"Nanotechnology has enabled numerous advances in communications, medicine, energy, and agriculture. But as the proliferation of nanomaterials ramps up, unintended consequences are becoming increasingly visible. A recent study examined the effects of silver nanoparticles on soils supporting the growth of maize. Findings revealed a 30% decrease in the relative abundance of members of the archaea community, which are important for nitrogen cycling in soil, vital for plant growth. Nanosilver also increased the abundance of certain possibly phytopathogenic fungi, possibly by eliminating bacteria that normally keep these harmful fungi in check. Finally, increased root growth seems unsustainable because it is probably caused by these stress factors, and not by beneficial effects. While this study was limited to relatively small, pot experiments, the findings suggest that the microbiome is an essential inclusion for studying the long-term effects of nanomaterials on the environment..."

This shows how Newton's method (also known as Newton-Raphson) is used to find a root of a function. You can show/hide various parts of the construction, and edit the particular function being considered.

"At the roots of plants, there is more than meets the eye. The rhizosphere – the soil in contact with plant roots – is home to a rich community of microbes that are tightly associated with plant roots. Microbes can benefit plants by increasing nutrient availability, producing plant growth hormones, and protecting against pathogens, while in contrast, soilborne pathogens can reduce plant growth and cause yield loss. A recent study sought to better understand how plants influence their associated root bacteria. Using a multi-selection system and infection by the soilborne pathogen Rhizoctonia solani AG8, researchers found that successive plantings enhanced disease suppression in wheat cultivars. Distinct bacterial community profiles assembled over successive plantings, and the cluster of bacterial communities in AG8-infected plants was different from those in uninfected plants. In infected plants, bacteria that act as antagonists to AG8 and promote plant growth were enriched..."

Root Search Engine is an engine hosted by the University of Leeds that allows users to search for the meaning of any Arabic root. To use the search engine, users must type the desired root in Arabic. Users also have the option of using the installed Yamli plug-in, which converts words typed with Latin characters to their closest Arabic equivalent. The engine provides results from various dictionaries such as Lis_n Al-ÔArab, among many others.

This course will explore the rich diversity of women’s voices and experiences as reflected in writings and films by and about Latina writers, filmmakers, and artists. Through close readings, class discussions and independently researched student presentations related to each text, we will explore not only the unique, individual voice of the writer, but also the cultural, social and political contexts which inform their narratives. We will also examine the roles that gender, familial ties and social and political preoccupations play in shaping the values of the writers and the nature of the characters encountered in the texts and films.

From paving your patio to measuring the ingredients for your latest recipe, squares, roots and powers really are part of everyday life. This unit reviews the basics of all three and also describes scientific notation, which is a convenient way of writing or displaying large numbers.

This article describes an approach designed to decrease math anxiety and teach students about the use of mathematical symbols simplifying radicals. A deck of cards is used in a demonstration, and a problem set using real life examples to master the use of radicals is included. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This course considers reggae, or Jamaican popular music more generally—in its various forms (ska, rocksteady, roots, dancehall)—as constituted by international movements and exchanges and as a product that circulates globally in complex ways. By reading across the reggae literature, as well as considering reggae texts themselves (songs, films, videos, and images), students will scrutinize the different interpretations of reggae’s significance and the implications of different interpretations of the story of Jamaica and its music. Beginning with a consideration of how Jamaica’s popular music industry emerged out of transnational exchanges, the course will proceed to focus on reggae’s circulation outside of Jamaica via diasporic networks and commercial mediascapes. Among other sites, we will consider reggae’s resonance and impact elsewhere in the Anglo Caribbean (e.g., Trinidad, Barbados), the United Kingdom (including British reggae styles but also such progeny as jungle, grime, and dubstep), the United States (both as reggae per se and in hip-hop), Panama and Puerto Rico and other Latin American locales (e.g., Brazil), Japan and Australia, as well as West, South, and East Africa (Côte d’Ivoire, Tanzania, Uganda).

When you eat a salad for lunch, you’re digging into a giant pile of plant organs. That’s right—plants are made up of organs, only theirs follow a totally different set of rules from our own. In this episode of Crash Course Botany, we’ll explore what it takes to build a plant, including roots, leaves, and stems, and how one little tomato went all the way to the U.S. Supreme Court.
