Students will examine a relief sculpture, focusing on its style, function, and design. They will then create a three-dimensional sketch for a decorative overmantel for a patron of their choice as part of an extreme home makeover. This sketch should reflect a current fashionable style.

Microbiology is the study of microorganisms, which are tiny organisms that can only be seen with a microscope. Microorganisms include bacteria, viruses, fungi, and protozoa. Microorganisms are found everywhere in the environment, including in water, soil, air, and in the bodies of plants and animals. Microbiology is an important science that helps us to understand how microorganisms interact with each other and with their environment. Microbiology also helps us to understand how microorganisms can cause disease and how they can be used to produce food and medicines. Teaching microbiology can be a fun and interesting experience for students. There are many different ways to teach microbiology, and the best way to teach it will depend on the students’ age and level of education. One way to teach microbiology is to use learning materials that are specifically designed for schools. These materials can help to make the learning process more fun and interesting for students. Some of the best practices for developing microbiology learning materials for schools include: 1. Developing materials that are age-appropriate 2. Using fun and interactive activities 3. Incorporating images and videos 4. Using real-world examples 5. Including assessment questions

Embryo, when applied to mammals, is the term given to the developing organism from fertilisation to birth. Developmental biology, or embryology, is the study of the embryo as it transforms from a unicellular zygote to a multicellular, mulitsystemed organism which in some cases is ready to function autonomously at birth. Developmental biology is of interest to vets in understanding why organs and systems are the way they are, but also in understanding genetic diseases and applying cell based therapies to treat loss or damage to tissues.

The Developmental and Reproductive Toxicology and Environmental Teratology Information Center (DART/ ETIC) Database is made available by the National Library of Medicine's Toxicology Data Network. The database contains over 100,000 current and earlier literature citations covering teratology and other aspects of developmental and reproductive toxicology. Users may search the database by subject, title words, chemical name, Chemical Abstracts Service Registry Number, and author. The Web site also includes a useful help page and sample record for familiarizing oneself with the database.

This site from the National Park Service briefly addresses the geology of Devil's Tower. The evolution of various theories on the formation of the tower are discussed. A slide show of the emplacement of the tower is also available.

"An international team of researchers is looking at ways to prevent cognitive impairment following the use of general anesthetics. Their work could lead to better outcomes for the over 312 million surgical patients who undergo anesthesia each year. General anesthetics are associated with the occurrence of postoperative delirium. This complication – often marked by inattention, memory disturbances and confusion – makes it hard for surgical patients to resume daily living activities, and has even been linked to an increased risk of death. The drug dexmedetomidine helps prevent postoperative delirium, but the biological basis for this protection isn’t clear. The researchers previously reported that a single exposure to the common anesthetic etomidate can trigger long-lasting changes to an inhibitory receptor in the brains of mice. Specifically, etomidate increased the number of α5 GABAA receptors expressed on the surface of neurons..."

This diagram of Hawaii's Kilauea volcano shows the underground "plumbing" and paths of magma.

A diagram of cells changing shape from columnar to stratified, as they roughly may do as a transitional epithelium changes shape, as well as a diagrammatic explanation of why they must change shape to maintain a barrier.

The Diaphragm is a dome-shaped musculotendinous sheet separating the thoracic and abdominal cavities. It is convex on its cranial surface. In the neutral position between full inspiration and full expiration, the most cranial part of the diaphragm is in line with the 6th rib.

"Diarrhea kills hundreds of thousands of children each year, making it one of the leading causes of childhood mortality. It’s also rampant in the livestock industry, where it causes huge losses. Diarrhea can be induced or facilitated by disruption of the gut microbiome at the colonic mucosal barrier. However, the contributions of abnormalities in barrier components called mucin O-glycans remain unclear. To learn more, researchers recently investigated the changes in microbiota- associated mucin O-glycans in a piglet post-weaning diarrhea model. Diarrhea (D) altered the structure of the colon mucus layer and changed the O-glycan profile. For example, it reduced the abundance of acidic O- glycans while increasing that of truncated O-glycans. Subsequent changes in the microbiota disrupted barrier function, which increased inflammation and ultimately impaired piglet growth..."

The collection presents three manuscript volumes, totaling 1,240 digital images, that document daily life in Washington, D. C., through the eyes of Horatio Nelson Taft (1806-1888), an examiner for the U. S. Patent Office. The diary details events in Washington during the Civil War years including Taft's connection with Abraham Lincoln and his family. Of special interest is Taft's description of Lincoln's assassination, based on the accounts of his friends and his son, who was one of the attending physicians at Ford's Theatre the night Lincoln was shot, on April 14, 1865.

"Plants host a variety of soil microbes on their roots. This root microbiome can affect plants in different ways, including the production of hormones to spur plant growth. In turn, plants also alter the root microbiome, which has been shown to be affected by plant genotype. But it’s been unclear whether the root microbiome is influenced by plant epigenetic factors, which regulate the readouts of genetic information. In the model organism Arabidopsis thaliana, new DNA methylation, an important epigenetic mark, occurs through the RNA-directed DNA methylation (RdDM) pathway. So researchers decided to look for changes in the root microbiota among mutant Arabidopsis plants defective in the canonical RdDM pathway. In the dcl234 triple mutant, which has defects in three Dicer-like proteins that produce small RNAs, the team found an altered microbiome composition. Mutations in other examined parts of the RdDM pathway, however, did not result in changes to the microbiome..."

"Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders worldwide. IBS can have profound effects on quality of life, and treatment options are limited. While several studies have found associations between dietary habits and the gut microbiome in healthy individuals, studies in patients with IBS are limited. To better understand this relationship in IBS, researchers studied food diary data and sequenced gut microbiota in 149 individuals with IBS and 52 healthy controls. They found that individuals with IBS tended to show a higher intake of poorer quality food during main meals. Covariation between gut microbiota and diet corresponded with IBS symptom severity, exhaled gas, glycan metabolism, and meat/plant ratio, and IBS severity was associated with altered gut microbiota hydrogen production, with changes seen in enzymes involved in carbohydrate metabolism..."

"Fructo-oligosaccharides (FOS), inulin, and galacto-oligosaccharides (GOS) are well-known prebiotics with beneficial effects on the intestinal microbiota and host health. Combining dietary FOS and inulin with calcium phosphate stimulates commensal Lactobacillus and protects the host against pathogenic Enterobacteriaceae. However, the effects of combining dietary GOS with different calcium phosphate levels are unclear. To learn more, a recent study analyzed the microbiomes of rats fed diets with or without GOS or inulin plus a high or low level of calcium phosphate (Hca or Lca, respectively). After two weeks, the researchers performed rRNA gene sequencing and organic acid profiling on fecal samples. The Hca diets favored Firmicutes bacteria, while the Lca diets favored mucin-degrading Bacteroidetes and Verrucomicrobia bacteria. Regardless of the calcium phosphate level, GOS and inulin strongly stimulated Bifidobacterium abundance..."
