Over the past few decades, genetic research has revealed two deep truths about people. The first is that all humans are closely related-more closely related than all chimps, even though there are many more humans around today. Everyone has the same collection of genes, but with the exception of identical twins, everyone has slightly different versions of some of them. Studies of this genetic diversity have allowed scientists to reconstruct a kind of family tree of human populations. That has revealed the second deep truth: In a very real sense, all people alive today are Africans.

"Scientists have sequenced the complete genome of the naked mole rat, a pivotal step to understanding the animal's extraordinarily long life and good health."

U.S. researchers have found that Zika can attack special populations of brain cells in adult mice in the part of the brain involved in learning and memory, raising new questions about how the virus may be impacting millions of adults who have been infected with the virus. The findings, published on Thursday in the journal "Cell Stem Cell," are the first to look at whether Zika can attack the same kinds of cells in adult mice that they do in fetal mice.

Microsoft scientists have demonstrated that by analyzing large samples of search engine queries they may in some cases be able to identify internet users who are suffering from pancreatic cancer, even before they have received a diagnosis of the disease.

But scientists from the University of Southern California showed that, in mice, the Fasting Mimicking Diet (FMD) significantly lowered the percentage of damaging immune cells, while allowing the protective coating to regrow.

Four talks focus on sex determination-the molecular and genetic mechanisms that determine whether an organism will be male, female or a hermaphrodite.

 This session will showcase several PBL lessons and units that incorporate multiple Common Instructional Framework Strategies and authentic inquiry experiences in order to facilitate mastery of science concepts.

CASES Online is a collection of inquiry-based lessons to engage K-12 and undergraduate students in exploring the science behind real-world problems. Through CASES, you can transform your students into motivated investigators, self-directed and life-long learners, critical thinkers and keen problem solvers. Our cases are grounded in Problem-Based Learning (PBL), Investigative Case-Based Learning (ICBL), and related student-centered pedagogies.

This web site provides tools and resources that support ambitious science instruction at the middle school and high school levels. Ambitious teaching deliberately aims to get students of all racial, ethnic, and class backgrounds to understand science ideas, participate in the discourses of the discipline, and solve authentic problems. We describe 4 core instructional strategies that support this kind of teaching. These "high-leverage" practices make up the Science Learning Framework (below), and have been selected based on extensive research of how young people learn science, on authentic forms of science activity, and how teachers learn to appropriate new practices.

This interactive case discussion was created to emphasize the clinical relevance of population genetics, but is also a suitable resource for teaching the basic principles of population genetics while relating them to human genetic variation. Our understanding of human genetic variation has deepened over the past decade due to fine-scale genome mapping. Applying this knowledge to the evaluation of ancestry-based genetic testing strategies, such as direct-to-consumer genetic testing, is an important component of the practice of culturally-competent medicine and a relevant way to teach the foundations of population genetics, including Hardy-Weinberg equilibrium.
