The Birds-of-Paradise Project reveals the astounding beauty of 39 of the most exquisitely specialized animals on earth. After 8 years and 18 expeditions to New Guinea, Australia, and nearby islands, Cornell Lab scientist Ed Scholes and National Geographic photojournalist Tim Laman succeeded in capturing images of all 39 species in the bird-of-paradise family for the first time ever. This trailer gives a sense of their monumental undertaking and the spectacular footage that resulted.

The Nib" recently posted a cartoon that breaks down vaccine history, hysteria and necessity all in one easy-to-read and understand cartoon.

This case study details the historical discovery of the structure of DNA. Images of this key molecule are as iconic as those of the Mona Lisa, and identifying its structure has proven to be as intriguing a mystery for scientists as the reason behind Mona Lisa's smile has been for art historians. The case is woven together by a series of fictional diary entries that detail the history of the discovery of DNA's structure, the major players involved, their ethical dilemmas, and the role of women in science. The case is designed for a high school course or introductory undergraduate genetics/ biochemistry courses. It can also be used as an interdisciplinary case study bridging genetics, bioethics, art, and the status of women in science. Designed as an interrupted case, it may be used in its entirety or in parts that pertain to a particular topic or discipline. No prior knowledge of genetics is required.

Taxonomy groups species by common traits. Modern taxonomy emphasizes evolutionary relatedness. Explore some principles of taxonomy by sorting twenty shells by their morphological characteristics. Whenever a pictorial index of shells appears, you can click on an image of a shell to open it in a separate window. There you can click and drag your mouse over the shell to rotate it for a more detailed examination. Additionally, you can use the small buttons in the lower right corner of the window to rotate the shell.

In the animal kingdom, humans are known for our big brains. But not all brains are created equal, and now we have new clues as to why that is. Researchers have uncovered eight genetic variations that help determine the size of key brain regions. These variants may represent "the genetic essence of humanity," says Stephan Sanders, a geneticist and pediatrician at the University of California, San Francisco, who was not involved in the study. These results are among the first to come out of the ENIGMA (Enhancing Neuro Imaging Genetics through Meta-Analysis) collaboration, involving some 300 scientists from 33 countries. They contributed MRI scans of more than 30,000 people, along with genetic and other information, most of which had been collected for other reasons. "This paper represents a herculean effort," Sanders says.

BodyMaps is an interactive visual search tool that allows users to explore the human body in 3-D. With easy-to-use navigation, users can search multiple layers of the human anatomy, view systems and organs down to their smallest parts, and understand in detail how the human body works. Using detailed 3-D models of body parts-including muscles, veins, bones, and organs-BodyMaps offers a new way to visualize and manage your health. See how the coronary artery delivers blood to the heart, and learn how plaque build-up on artery walls leads to heart disease. Locate the exact location of a pulled muscle or broken bone, and find information on how to prevent injuries. View a cross-section of the human brain, and learn which areas control certain emotions and body functions. By offering rich, detailed anatomical images alongside links to relevant and useful health information, BodyMaps allows you to leam about your body and your health in a personalized and revolutionary new way.

Scientists have genetically engineered monkeys so that they exhibit behaviors similar to autism, with a goal of testing potential therapies on the animals in hopes that their resemblance to humans will yield more answers about the disorder. The scientists found that the monkeys showed "very similar behaviors related to human autism patients, including repetitive behaviors, increased anxiety and, most importantly, defects in social interactions," said Zilong Qiu, a leader of the research at the Institute of Neuroscience at the Chinese Academy of Sciences in Shanghai. The team is now imaging the brains of the monkeys, he said, "trying to identify the deficiency in the brain circuits that is responsible for the autism-like behavior."

His "Photo Ark" currently houses images of more than 5,000 species, rolling past the viewer. "It would take two hours to see them all," he said. "It's supposed to just overwhelm people with what life looks like on Earth." And what might soon be extinct.

This case study follows two beginning undergraduate researchers on a quest for a summer research project related to food web ecology. While writing their research proposal, the students receive feedback indicating that they have neglected an entire group of organisms from their food web-parasites, which leads them to a scientific research paper discussing how these organisms have been overlooked by scientists studying food webs, the challenges involved with including parasites in food webs, and the contributions parasites ultimately make to food webs. An integrated activity in which students visualize the food web using images of organisms and answer questions about species interactions provides opportunities to examine key concepts such as omnivory, ontogenetic diet changes, trophic levels, complex life cycles, and taxonomic aggregation. This case study was originally written for an undergraduate general ecology course, but could easily be adapted to undergraduate general biology courses covering community ecology or specific courses in invertebrate zoology, parasitology, or disease ecology. The teaching notes also discuss how the included code for R statistical computing software can be used to extend the case study in a more quantitative direction if desired.

By taking near-atomic, high-resolution X-ray images of proteins from primitive bacteria, investigators at Arizona State University and Pennsylvania State University have extrapolated what the earliest version of photosynthesis might have looked like nearly 3.5 billion years ago.

DNA has a double helix structure. If untwisted, DNA looks like two parallel strands. Each strand has a linear sequence of A, C, G, and T. The precise order of the letters carries the coded instructions. One strand is a complementary image of the other: A always pairs with T, and C always pairs with G.

This interdisciplinary case study uses the format of a progressive disclosure to explore certain advances in biotechnology and evaluate them within the framework of societal needs, concerns and pressures.  When faced with a heart valve transplant, a high school student and her mother must decide between multiple approaches, some current and others emergent. Highlighted in this case study are the topics of xenotransplantation, 3D bioprinting and the mature minor rule. The case includes a role-playing, public hearing activity that can be used to explore many aspects at the interface of technology and culture: religious rights, parental rights, public health care policy and safety, animal rights, economic issues of organ marketing, and psychological issues of body image.  This case study was originally designed for first year collegiate classes (introduction to biology, introduction to psychology) but is also applicable to AP high school. The flexible nature of the case also allows for expansion of several aspects for advanced classes across multiple disciplines.

"That changed when NASA created the Landsat program, a series of satellites that would perpetually orbit our planet, looking not out but down. Surveillance spacecraft had done that before, of course, but they paid attention only to military or tactical sites. Landsat was a notable exception, built not for spycraft but for public monitoring of how the human species was altering the surface of the planet."

This interactive module introduces the anatomy of the immune system and walks through the timeline of a typical immune response.  The timeline includes the differences between the first time a pathogen is encountered versus subsequent infections, including an explanation of how vaccines work. Different tabs, videos, images, questions, and a detailed glossary of terms allow this resource to be explored at varying levels of depth depending on the class. Refer to the "Educator Resources" tab in the Click & Learn for implementation suggestions.
