Early classification systems probably grouped organisms as to whether they were beneficial or harmful. Another ancient classification system recognized 5 animal groups - domestic animals, wild animals, creeping animals, flying animals, and sea animals.

Why is their so much secrecy in animal research? Can't we do without animals in medical research? In this video Dr Simon Festing, our ex-Chief Executive, answers questions about why animals are an essential part of medical work. Download this film here: http://ww

An international team led by Professor Itai YanaAi of the Technion-Israel Institute of Technology Department of Biology made the discovery after using an extraordinarily powerful technique known as CEL-Seq. CEL-Seq monitors individual cells for their gene activity (as detected via mRNA)-and they applied it across 10 different species, with CEL-Seq being applied to 70 embryos per species. In particular, they were interested in whether the animal classification of phylum-which separates animals into groups according to their body plans-is actually a useful tool for placing animals into groups, as well as what genetic attributes are the same and different between the different phyla.

Australian outfit Bridge 8, who have the admirable mission of devising "creative strategies for science and society," and animator James Hutson have created six fantastic two-minute animations on various aspects of critical thinking, aimed at school ages 8 to 10, or kids between the ages of 13 and 15, but also designed to resonate with grown-ups. Inspired by the animation style of the 1950s, most recognizably Saul Bass, the films are designed to promote a set of educational resources on critical thinking by TechNYou, an emerging technologies public information project funded by the Australian government.

These 106 in-depth tutorials are designed to illustrate and explain some of the many complex topics in biology. Each tutorial has four elements: an introduction that describes the topic to be illustrated and puts it into a broader context, a detailed animation that clearly illustrates the topic (there are a few tutorials that include simulations or other types of content, rather than animations), a conclusion that summarizes what you should have learned from the animation, and a quiz on the topic covered.

Scientists once shied away from naming research animals, and many of the millions of mice and rats used in U.S. research today go nameless, except for special individuals. But a look at ​many facilities suggests that most of the ​other ​891,161 ​U.S. ​research animals ​have proper names​, including nonhuman primates, dogs, pigs, rabbits, cats, and sheep​.

Research leading to almost every Nobel Prize in Medicine awarded since 1901 was dependent on data from animal models.  This fact dramatically demonstrates the important contribution animal models in biomedical research make to both international and American medical progress. In fact, since 1979, every Nobel Prize in Medicine awarded was dependent on data from animal models with the exception of the 1983 Prize awarded to Dr. Barbara McClintock for her work in plant genetics.

Shape of Life is a series of FREE short classroom videos that beautifully illustrate the evolution of the animal kingdom on planet earth. Based upon an original PBS Series, Shape of Life is especially designed for students and teachers who want a first-hand account of how animals adapt and thrive. The series is NGSS aligned with exquisite focus on diversity, biodiversity, adaptability, body structure, design, behaviors, and the innovative scientists who explore these creatures.

Scientists work with animal models to better understand type 2 diabetes to treat the disease. They have developed specialized animal models that mimic the condition.  One line of mice, known as KK mice, develop obesity and glucose intolerance that lead to type 2 diabetes. Another rodent model, the Zucker diabetic fatty rat, is bred to be a precise model of human type 2 diabetes.

In most animals, the drive to breed and produce offspring is strong. However, most males live their whole lives without having the chance to breed. The events leading up to mating can be very dangerous and also very costly to an individual. Some males have evolved elaborate structures, or weapons, as a result. The structures do help males in both combative situations and with attracting females, but ironically, the structures themselves come with certain costs. This flipped case study provides students with the opportunity to not only see how animal structures and functions are linked, but also to see how certain animal structures are needed and costly. There are videos that students are expected to view before the case. The case was initially designed for a second semester college general biology class for majors. However, it can also be used in non-major biology classes. Students should have some background knowledge of natural selection, specifically sexual selection as well as energetic demands of certain structures.

FEBRUARY 20, 2015-A diverse group of experts from academia, industry and advocacy convened by a Georgetown researcher is offering recommendations to the National Institutes of Health (NIH) regarding how to address the overreliance of male cells and animals used in preclinical studies. The recommendations come as the federal research institution works to increase the inclusion of female animal models and achieve a balance in the use of male and female cells and animals in lab research.

Recently, in an article in the New Republic, 'The Animals That Can Save Your Life', journalist Emma Young introduces readers to the emerging science of training animals to detect things humans cannot.

Hear from some of the country's leading scientists and medical experts who talk about why animal research is critical for medical progress and the advancement of both human and animal health.

Meiosis, the form of cell division unique to egg and sperm production, sets the stage for sex determination by creating sperm that carry either an X or a Y sex chromosome. But what is it about the X or Y that determines sex? Before a meiotic cell divides, its two sets of chromosomes come together and cross over, or swap, segments. The first animation shows normal crossing over, where the X and Y chromosomes exchange pieces only at their tips. The second animation shows a rare mistake in which the Y chromosome transfers a gene called SRY to the X chromosome, resulting in sex-reversed babies. Studies of sex-reversed individuals led researchers to identify the master switch for sex determination, the SRY gene, which tells a fetus to become a boy.

Protein folding and trafficking is essential for normal cell function, and when it goes awry it can lead to various chronic conditions, including fatty liver disease, diabetes, and Parkinson's. The narrative of this case study follows two undergraduate students engaged in a summer research project evaluating the effects of cell stress on cell function and health in the model organism Caenorhabditis elegans (C. elegans).  During the case study, students review animal cell organelle function and then learn about endoplasmic stress and unfolded protein response. Prior knowledge needed for the case is basic animal cell organelles and their functions and use of model organisms in research. The case was designed for a flipped classroom in which students prepare in advance by taking a quiz and watching two videos; a PowerPoint animation is also included.

The uproar over the new ease and precision with which scientists can manipulate the DNA of living things has centered largely on the complicated prospect of editing human embryos. But with the federal government's approval last week of a fast-growing salmon as the first genetically altered animal Americans can eat, a menagerie of gene-edited animals is already being raised on farms and in laboratories around the world - some designed for food, some to fight disease, some, perhaps, as pets.
