DNA Hybridization
No full textThis animated YouTube video, created by Southwest Center for Microsystems Education (SCME), illustrates how DNA hybridization works in the context of nanofabrication. The animation and associated narration describe "DNA hybridization is when a single-stranded DNA (ssDNA) molecule bonds with a complementary ssDNA molecule from another source forming a "hybrid". This animation shows a double-stranded DNA (dsDNA) molecule dividing into two ssDNA strands. One ssDNA remains on the substrate as the "probe". A complementary ssDNA from another source (a ssDNA with a complementary base pair sequence) joins with the probe forming a 'hybrid' dsDNA molecule." A supporting learning module and activities can be downloaded from the SCME website
Deposition Overview - Part I
No full textThis YouTube video, created by Southwest Center for Microsystems Education (SCME), provides an overview of the deposition processes used to fabricate micro-sized devicesâ. The lecture runs for 12:53 seconds and covers the basics of desposition, as well as spin-in deposition and thermal oxidation. More information on desposition can be found on the SCME website.Â
MEMS Pressure Sensor Operation
No full textThis animation, created by Southwest Center for Microsystems Education (SCME), allows viewers to observe the operation of a micropressure sensor and the packaging of a micropressure sensor array. The animation illustrates "the sensing circuit for the pressure sensor is a Wheatstone Bridge configuration with two variable resistors (strain gauges) that change in resistance with a change in pressure. The sensing circuit is mounted on top of a fixed pressure chamber referred to as the reference chamber. When the pressures above and below the sensing circuit are different, the membrane flexes causing a change in bridge resistance." A supporting learning module, Wheatstone Bridge, can be downloaded from the SCME website under Educational Materials
ATE Student Success Stories: Dan's Story
No full textDaniel Burman had a successful career in real estate but was never happy. That all changed when he returned to school to study solar photovoltaics. He's now working in the alternative energy field with a local business and is not only making a good living, but also feeling excited about his job and career choice.To download this video and/or captions, visit: https://atecentral.net/index.php?P=StudentSuccessStorie
Learn.Genetics: Variation, Selection & Time
No full textThe Scout Report has profiled the Genetic Science Learning Center website from the University of Utah in the past, but the website's authors continue to add material of note. This latest offering looks into the genetic variables of variation, selection, and time. As the site notes, "In our ever-changing world, a naturally occurring genetic difference in an individual can become an advantage or a fatal flaw in the struggle for survival." Visitors can start with the introductory section, titled "Recipe for Evolution," to explore an interactive "recipe" that's both fun and edifying. Moving on, the "Things You May Not Know About Evolution" looks into common misconceptions about the process of evolution. Finally, visitors can also use the Evolution in Action area to explore evolution in the stickleback fish and rock pocket mice
The Scientist - Multimedia
No full textThe Scientist magazine is written for life science professionals, but promises it to be "concise, accurate, accessible, and entertaining." The magazine's online version has a great Multimedia section on its website that has "Videos," "Slideshows," and "Infographics." Visitors shouldn't miss the story titled "Bat Hunt" from the January 2012 issue, which profiles a mammologist working in the South Sudan. The photographs in included this story are excellent, and visitors will be amazed by the photo of the wide-eyed fruit bat cradling its baby. Back on the homepage, the Infographics section contains stories accompanied by colorful, easy-to-follow diagrams, and it is also well worth a look
Structures and Functions of Genomes
No full textThe BioEd Online website brings together a range of resources designed to help biology teachers educate their students about everything from microbes to genetics. This particular slide set was created by Dr. Raye L. Alford and it uses diagrams, charts, and a range of other illustrative materials. The topics covered here include mitochondria, eukaryotic genomes, and chromatin and DNA packaging. Visitors can download all of the slides at one time, or they can also search materials on each slide individually. It's worth noting that visitors can share these materials via Twitter and social media using the handy links on the site
The A&P Professor
No full textKevin Patton is the president emeritus of the Human Anatomy and Physiology Society (HAPS) and he is also the brains behind the A&P (Anatomy & Physiology) Professor website. Patton has worked to create this online collection of resources for people teaching human anatomy and physiology, and it's a great counterpart to his blog of the same name. Visitors should start by looking over one of the five tabs at the top of the page, which include Resources, Topics, and How To. The How To contains resources for educators about producing online lectures and various in-class student response systems. The files here are dynamic, and they include interactive sections that make the material quite lively. Moving on, the Resources area includes an online version of an anatomy & physiology textbook created by Patton, along with links to other high-quality resources. Finally, the Lion's Den section of the site contains links to Patton's syllabi, course handouts, and a range of introductory materials for anyone who might be teaching a basic anatomy & physiology course
Using Job-Shadowing Experiences
No full textIn this professional development video adapted from Getting Results, a student and a microbiologist talk about the studentâs job-shadowing experience in a biotechnology lab. The microbiologist explains how the experience exposes the student to the profession, thus, helping her make decisions about her future career. The student describes how the job-shadowing helps her understand what is involved in a biotechnology job. The video runs 3:44 and is accompanied by a background essay and discussion questions. Users who sign up for a free account can save the resource and download the video as well
