Be “Cool” with Popsicle Engineering
Read the Fine Print
Educational Use
Rating
0.0 stars

Beginning kindergarteners are introduced to science and engineering concepts through questions such as “What is a Scientist?” and “What is an Engineer?”, and go on to compare and contrast the two. They are introduced to five steps of the engineering design process and explore these steps using the “I do, we do, you do” set of guided instruction. At the end of the project, students produce a set of purple popsicles that they design using various materials and by following a set of criteria.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Corncob structures in dental plaque reveal specificity of microbial interactions

0.0 stars

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:

"Our mouths are a vast jungle of microbial life. Here, more than 700 distinct types of microbes make their home, but not everywhere all at once. Each region (the tongue, teeth, gums, etc.) hosts a unique community of microorganisms. To explore this complex living structure, researchers examined the community of bacteria found in the dental plaque of 14 healthy volunteers. Samples indicated the well-known formation of intricate corncob-like structures, where a central filament made of cells of Corynebacteria (magenta) is decorated with “kernels” of spherical Streptococcus bacteria (green). A closer look revealed that these kernels can be composed of a single species of bacteria or contain mixtures of different species. The major corncob species were common to all 14 donors. Corncob composition likely was dictated by the metabolic and binding interactions shared between corncob residents..."

Rating
0.0 stars

Students will learn to fabricate, remix, and design detection and monitoring devices for health following the core focus of the Tricorder: a portable, handheld diagnostic device which can brings health solutions to consumers at home or in remote parts of the world. Inspired by the Tricorder X-Prize (with a purse of $10 million), students will aim to create specific component technologies that integrate into a comprehensive Tricorder mechanism capable of reading vital signs and specific disease biomarker detection. Component areas will include optical, electric, biochemical, and molecular diagnostics.

Students are introduced to genetic techniques such as DNA electrophoresis and imaging technologies used for molecular and DNA structure visualization. In the field of molecular biology and genetics, biomedical engineering plays an increasing role in the development of new medical treatments and discoveries. Engineering applications of nanotechnology such as lab-on-a-chip and deoxyribonucleic acid (DNA) microarrays are used to study the human genome and decode the complex interactions involved in genetic processes.

Educational Use
Rating
0.0 stars

Students are introduced to the latest imaging methods used to visualize molecular structures and the method of electrophoresis that is used to identify and compare genetic code (DNA). Students should already have basic knowledge of genetics, DNA (DNA structure, nucleotide bases), proteins and enzymes. The lesson begins with a discussion to motivate the need for imaging techniques and DNA analysis, which prepares students to participate in the associated two-part activity: 1) students each choose an imaging method to research (from a provided list of molecular imaging methods), 2) they research basic information about electrophoresis.

"Animals and plants have close relationships with the bacteria on their surfaces and macroalgae — like kelp — are no different. The spatial structure of these microbial communities can impact how they interact with their neighbors, host, and environment. A recent study used spectral imaging to characterize the spatial structure of the bacteria on _Nereocystis luetkeana_. The kelp hosted a dense microbial biofilm that consisted of closely associated, but diverse, microbial taxa. For example, Gammaproteobacteria were found close to the kelp surface, and filamentous Bacteroidetes and Alphaproteobacteria were concentrated near the biofilm-seawater interface. Bacterial density also varied along the length of the kelp blades with density increasing from new tissue at the base to older tissue at the blade tips. Between kelp populations, declining populations hosted fewer microbial cells than kelp from a stable population. This study characterized the dense, spatially differentiated community on _N..."

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:

"During epithelial-mesenchymal transition (EMT), epithelial cells lose their polarity and their cell-cell connections to become mobile, in part via transcription factor (TF) activation. EMT and its reverse process, MET, are critical for tissue development in embryos, and EMT enables wound healing during adulthood, but EMT is also how cancer cells metastasize. Live imaging of animal embryos can yield important insights into these key processes. For example, FGF and actomyosin have been found to regulate intercellular adherens junction (AJ) remodeling during EMT in fruit flies. In addition, in zebrafish embryos, the planar cell polarity (PCP) protein pk1 ensures proper EMT of neural crest cells (NCCs), and cadherin 6 ultimately regulates NCC migration..."
