This interactive infographic from the National Academies Press highlights essential practices for K-12 science classrooms from A Framework for K-12 Science Education with references to the contents of the full report.

A new study by Duke University researchers helps clarify the matter by showing how a sugar habit changes specific brain circuits, and how those changes produce cravings that reinforce the habit. The research team began by getting a group of healthy mice hooked on sugar. Similar to classic studies on drug addiction, the mice in this study were trained to press a tiny lever to receive doses of sweets. Once the mice were hooked, they continued pressing the lever even when the sweets were removed. So that was step one, establishing a behavioral pattern to get the goods.

"We risk being in a post-antibiotic world," said Thomas Frieden, director of the U.S. Centers for Disease Control and Prevention, referring to the urinary tract infection of a 49-year-old Pennsylvania woman who had not traveled within the prior five months. Frieden, speaking at a National Press Club luncheon in Washington, D.C., said the bacteria was resistant to colistin, an antibiotic that is reserved for use against "nightmare bacteria."

"There has been an over-reliance on male animals in preclinical research in the past, and as we have worked to study female specific physiological conditions, we became aware that even many aspects of our basic model of diet induced obesity are different in females," Erin Giles, assistant professor at Texas A&M University and lead author of the study, said in a press release.

About QUEST A collaboration of six public broadcasters around the country, QUEST is a multimedia series that strives to deepen our understanding of some of today's most pressing sustainability topics through articles, videos, radio reports, television broadcasts, and educational materials.

" White tigers today are only seen in zoos, but they belong in nature, say researchers reporting new evidence about what makes those tigers white. Their spectacular white coats are produced by a single change in a known pigment gene, according to the study, appearing on May 23 in Current Biology, a Cell Press publication."

Made possible through Toyota USA Foundation funding, the REMS curriculum options include nine online lesson plans and interactive activities themed to examine three pressing challenges in the US: preserving sustainable, competitive manufacturing; distributing products and services across the world; and developing and delivering efficient health care services. Each of the lesson plans provides age-appropriate math and science curriculum that tie to the Common Core Learning Standards for elementary, middle and high school students.

Aligned with both the Next Generation Science Standards and the Common Core State Standards, the investigations are designed to be much more authentic than traditional laboratory activities-and they enable your students to learn how to read, write, speak, and use math in the context of science.

This directed case study was developed to introduce students to the CRISPR-Cas9 system for genome editing. CRISPR-Cas9 has made numerous headlines in both the scientific and popular press, and thus serves as an excellent model for learning current biotechnology and applying concepts from biology courses. After providing a general overview of CRISPR-Cas9, the majority of the case focuses on the clinical applications of the system as experienced by a carrier for the X-linked recessive allele underlying Duchenne Muscular Dystrophy. The case is structured so that students use a variety of popular and scientific sources (some of which may require a subscription to access-check with your institution), increasing in difficulty as they move through each part of the case. The goals are for students to learn the molecular mechanisms of CRISPR-Cas9, the benefits and limitations of the system, and the clinical applications of the technology. Open-ended questions are included to spark discussion of ethical considerations, societal impacts, and the overall implications of the technology.

Since 2003, the H5N1 influenza virus, more commonly known as the bird flu, has been responsible for the deaths of millions of chickens and ducks and has infected more than 650 people, leading to a 60 percent mortality rate for the latter. Luckily, this virus has yet to achieve human-to-human transmission, but a small number of mutations could change that, resulting in a pandemic. Now a team of investigators from St. Jude Children's Research Hospital, Stanford University Medical Center, and MacroGenics have developed an antibody which has proven 100 percent protective against the virus in two species of animal models.

Biologists have long puzzled about how evolutionary selection, known for its ruthless requirement for efficiency, allows the existence of males - when in so many species their only contribution to reproduction are spermatozoa. But research published today in Nature shows that sexual selection - when males compete and females choose over reproduction - improves population health and protects against extinction, even in the face of genetic stress from high levels of inbreeding.

Officials in Panama have ruled that AquaBounty Technologies' has been operating in violation of environmental regulations as it experiments with genetically engineered (GE) salmon in that country. In a decision that could challenge the U.S. Food and Drug Administration's (FDA) ongoing safety assessment of AquaBounty's GE salmon, Panamanian officials fined the company $9500. Food & Water Watch, Center for Food Safety and Friends of the Earth called on the FDA today to terminate its regulatory review and deny AquaBounty's pending regulatory application to sell the company's GE fish in the United States.

"What is Ambitious Science Teaching? Great teaching can be learned. This web site provides a vision of ambitious science instruction for elementary, middle school and high school classrooms. Ambitious teaching deliberately aims to support students of all backgrounds to deeply understand science ideas, participate in the activities of the discipline, and solve authentic problems. We feature 4 core sets of teaching practices that support these goals. These core sets make up the Ambitious Science Teaching Framework. The framework has been based on classroom research from the past 30 years-research that has asked, "What kinds of talk, tasks, and tools do students need in order to fully engage in meaningful forms of science learning?""

Teaching K-12 Science and Engineering During a Crisis aims to describe what high quality science and engineering education can look like in a time of great uncertainty and to support practitioners as they work toward their goals. This book includes guidance for science and engineering practitioners - with an emphasis on the needs of district science supervisors, curriculum leads, and instructional coaches. Teaching K-12 Science and Engineering During a Crisis will help K-12 science and engineering teachers adapt learning experiences as needed to support students and their families dealing with ongoing changes to instructional and home environments and at the same time provide high quality in those experiences.
