Huntington disease is caused by a mutation in the HTT gene. Understanding how the mutation causes neurodegeneration might help researchers develop treatments that protect brain function. This animation describes the genetic defect that underlies Huntington disease. Created by the editors at Nature Reviews Disease Primers.

Science is working tirelessly night and day to disprove its own theories about how the universe works (or at least, that's what science thinks it's doing). Hank tells us a quick history of how we came to create and adopt the scientific method and then gives us a vision of the future of science (hint: it involves a lot more computers and a lot less pipetting).

4:43video, Vitamins are the building blocks that keep our bodies running; they help build muscle and bone, capture energy, heal wounds and more. But if our body doesn't create vitamins, how do they get into our system? Ginnie Trinh Nguyen describes what vitamins are, how they get into our bodies -- and why they are so crucial.

video 13:35, In which Hank does some push ups for science and describes the "economy" of cellular respiration and the various processes whereby our bodies create energy in the form of ATP.

Create, collaborate, and publish zooming and panning interactive timelines. It's like Google Maps, but for time.

Create tables, graphs, and maps illustrating cancer rates at the state or county level.

Dogs are excellent models for studying genetics, especially disease genetics. Work done in the last 20 years has shown that dogs share many gene-related disorders with people. Each breed is a closed reproductive population with distinct rates of heritable diseases, which dramatically increases the odds of finding disease-related loci. In creating new dog breeds, we reduce the gene pool within those populations, and fix many alleles. This homogeneous background makes it much easier to map QTLs and perform linkage analyses

Transgenic organisms, which contain DNA that is inserted experimentally, are used to study many biological processes. In this lab, you will create a transgenic fly to study circadian rhythms.

This initial module from the GENIQUEST project introduces the dragons and the inheritance of their traits, then delves into meiosis and its relationship to inherited traits. Students examine the effects of choosing different gametes on dragon offspring, and learn about genetic recombination by creating recombination events to generate specific offspring from two given parent dragons. Students learn about inbred strains and breed an inbred strain of dragons themselves. Lastly, students investigate a mysterious new dragon trait and use the properties of linkage and inheritance to examine the trait's relationship to other, known dragon traits.

TeachUNICEF is a portfolio of free global education resources. Resources cover grades PK-12, are interdisciplinary (social studies, science, math, English/language arts, foreign/world languages), and align with standards. The lesson plans, stories, and multimedia cover topics ranging from the Millennium Development Goals to Water and Sanitation. Our mission is to support and create well-informed global citizens who understand interconnectedness, respect and value diversity, have the ability to challenge injustice and inequities and take action in personally meaningful ways. We hope that in providing engaging and academically rich materials that offer multiple voices, we can encourage the exploration of critical global issues while presenting opportunities to take action.

In this lesson, students explore the fundamental mathematical concepts underlying the spread of contagious diseases. Using a simple exponential model, students compare and contrast the effects of different transmission rates on a population and develop an understanding of the nature and characteristics of exponential growth. Students can then compare their projections with actual Ebola data from West Africa, to create context for analyzing the strengths and limitations of this simplified model.

Gene Screen BC 2011 Participant. 18 Things You Should Know About Genetics is an animated film that presents fundamental background information about genetics, as well as offering some quirky but interesting facts about DNA, genes and genetics. It was created to be an upbeat, fun educational short film to initiate and draw interest to this sometimes daunting and seemingly complex subject matter.

Written for middle school/high school audiences, "The Gene Scene" ushers the viewer into the micro-biological universe of human DNA. I co-wrote the script for this short animation, which was created for an educational CD-ROM marketed to junior high and high schools around the English- and Spanish-speaking world. The colorful cartoon explains some of the basic scientific concepts of human genetics.

After her two children were diagnosed with a rare genetic condition, Sharon Terry dedicated her life to creating systems-level solutions that will alleviate burdens for consumers and build opportunities for them to be empowered in their own health care. She is the CEO of Genetic Alliance, an international non-profit organization, now in its 25th year, that is the world's largest network of health related organizations working from a consumer perspective. Genetic Alliance builds capacity within the genetics and health community by forging novel partnerships, promoting informed decision-making, and sharing individual, family, and community perspectives.

When you leave the house, does your dog or cat even remember you? Read More: A Rat's Tenacious Memory http://www.indiana.edu/~rcapub/v17n1/... "In the wild, rats scramble over the network of pathways they have created, combing their surroundings for food, water, mates, and shelter. Their movements may seem automatic to the untrained eye, simply a reflexive pattern. Decades ago, however, researchers established that rats know where they are going and remember where they have been."

Different disciplines follow different versions of the inquiry process. Graphic comparing: problem solving, scientific method, writing process, computation, theater, and engineering design.

The quest for artificial intelligence starts with Space Invaders. Researchers have created a new agent, capable of learning to play dozens of computer games from only minimal information. The work comes from inside the offices of mysterious Google-owned company DeepMind. Nature Video gets a rare glimpse inside.

While scientists study how nature works, engineers create new things, such as products, websites, environments, and experiences. Because engineers and scientists have different objectives, they follow different processes in their work. Scientists perform experiments using the scientific method; whereas, engineers follow the creativity-based engineering design process.

Well, it didn't happen only to you. It is often surprising how difficult it can be to find concrete biological numbers, even for properties that have been measured numerous times. To help solve this for one and all, BioNumbers (the database of key numbers in molecular biology) was created. Along with the numbers, you'll find the relevant references to the original literature, useful comments, and related numbers.
