The data comes from the open Tree of Life Project, a collaboration among biologists and other scientists around the world. It contains decades' worth of work in phylogeny, evolutionary history of and relationships among groups of organisms. The project is about a year away from a complete tree of all life, Rosindell said. He wanted a system in place that could visualize it as soon as it's ready. Right now, OneZoom only contains mammals, but that's still more than 5,000 species, all correlated with each other and color-coded according to their threat levels. Rosindell has big plans for the rest, and he even wants to build a searchable app for smartphones, showcasing the history and relationships between all life on Earth.

For centuries, women have studied and made groundbreaking discoveries in STEM (Science, Technology, Engineering, and Mathematics) fields. Encourage your girls and boys to appreciate the contributions of women scientists. With our seven ideas, learn about some outstanding women from the history of STEM innovation and inspire your kids' scientific explorations - indoors and outdoors.

This case study examines the molecular methods that were used to reverse engineer the 1918 influenza virus strain in order to try and solve the mystery of why it was so deadly. The story starts in the 1950s with the unsuccessful attempts to culture the influenza virus and follows scientists through to the turn of the century when cutting edge molecular tools enabled scientists to finally resurrect the 1918 virus through reverse genetics. The history and methods involved in resurrecting this deadly virus are reviewed in class with a PowerPoint presentation containing clicker questions (answered with a personal response system) and discussion questions (answered in small groups). This "clicker case" is suitable for high school biology and lower division undergraduate biology classes for non-majors. It could also be used in any lower division non-major class focused on human disease and the history of human disease.

In this directed case study students follow a nurse practitioner and work with a diagnostics team to determine what is wrong with Tristan, an infant who comes to the clinic with multiple bruises. Students are given background and patient history, and are then given results of various blood tests ordered by the diagnostics team. The exercise emphasizes the physiological process of coagulation and the importance of various clotting factors, especially factor VIII. Students will be introduced to results from several blood tests, including: complete blood count, partial thromboplastin time, prothrombin time, metabolic panel, and factor VIII assay. The patient is ultimately diagnosed with severe hemophilia A and the case then introduces students to this disorder, the genetic determinants, the incidence, and ways to manage the disease. The data in this case are real and the story represents the medical history of an actual patient. Originally developed for pre-nursing students, this activity would also be suitable for majors in physiology or pre-medical students; it could also be used in an introductory genetics or biology course.

The fates of ice age human groups in Europe were closely linked to climate change, according to an unprecedented study of the genomes of 51 individuals who lived between 45,000 years ago (when modern humans arrived in Europe) and 7,000 years ago. "We see multiple, huge movements of people displacing previous ones," David Reich of the Harvard Medical School said. "During this first four-fifths of modern human history in Europe, history is just as complicated as it is during the last fifth that we know so much more about."

Use this movie to spark discussion with students about what it means to be at risk, health family history and why it is important. The movie also acts as a teaser to excite student interest before doing the Risk Continuum and Pick The Risk activities.

Controversial new research suggests that contrary to the history books, the "Black Death" that devastated medieval Europe was not the bubonic plague, but rather an Ebola-like virus. History books have long taught the Black Death, which wiped out a quarter of Europe's population in the Middle Ages, was caused by bubonic plague, spread by infected fleas that lived on black rats. But new research in England suggests the killer was actually an Ebola-like virus transmitted directly from person to person.

The origins of the species known as 'the hobbit' - a human relative only a little over a metre tall - have been debated ever since its discovery in 2004. Now new fossils may reveal the ancestors of this strange species and help us to understand its history.

Amanda Briody describes two BioInteractive resources focused on Gorongosa National Park in Mozambique. She uses the short film "The Guide: A Biologist in Gorongosa" to introduce students to the park and its scientists. The Gorongosa Interactive Timeline allows her to ask data-based questions on the park's history and ecology, and have students make evidence-based claims.

Before the discovery of insulin in 1921, being diagnosed with Type 1 diabetes was a death sentence. Despite the successful management of diabetes with purified animal insulin, potentially severe side effects were abundant, and alternative ways to produce insulin were needed. This case study guides students through the history of using insulin to treat diabetes, focusing on the development of recombinant DNA technology and the world's first bioengineered drug, recombinant human insulin, which is now used worldwide to treat diabetes. Through the course of this case, students consider the central dogma of molecular biology, the development of recombinant DNA technology, drug design, the importance of recombinant proteins to our society, and the ethical analysis and debates that occur as a result of some scientific discoveries. This case was developed as an introduction to an upper-division biotechnology course focusing on recombinant protein design and production, but could also be used in molecular biology, biochemistry, or introductory biology courses to highlight recombinant DNA and biotechnology.

Hank takes us on a trip through time to revisit the 5 major mass extinction events that have impacted species over the Earth's history, and leaves us with some thoughts about what could possibly be the sixth event - the one caused by human activities.

The study by researchers from the Wellcome Trust Sanger Institute and collaborators at La Trobe University in Melbourne and several other Australian institutes, challenges a previous theory that suggested an influx of people from India into Australia around 4-5 thousand years ago. This new DNA sequencing study focused on the Y chromosome, which is transmitted only from father to son, and found no support for such a prehistoric migration. The results instead show a long and independent genetic history in Australia.

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.
