Dynamic Remodeling of Individual Nucleosomes Across a Eukaryotic Genome in Response to Transcription
The eukaryotic genome is packaged as chromatin with nucleosomes comprising its basic structural unit, but the detailed structure of chromatin and its dynamic remodeling in terms of individual nucleosome positions has not been completely defined experimentally for any genome. We used ultra-high–throughput sequencing to map the remodeling of individual nucleosomes throughout the yeast genome before and after a physiological perturbation that causes genome-wide transcriptional changes. Nearly 80%
Bioterrorism: plague as a biological weapon
Bioterrorism is the utilization of microorganisms or toxins in order to produce a disease and/or death in human beings, animals or plants. Different from conventional weaponry, relatively economic means are used that allow the elimination of living beings without destroying the surrounding atmosphere. The most probably method for spread of bioweapons is aerial transmission, continuing into water supplies and food. The CDC (US Centers for Disease Control and Prevention, Atlanta) has subdivided in
Journey to the Bottom of the Sea
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about how living in the water differs from living on land. An ichthyologist first explains that ocean creatures have special features that allow them to breathe, eat, communicate, and move in water. (Each feature has its own trading card, which provides more detailed info.)Then students are challenged to "try to make the connection" by playing the Journey to the Bottom
Eye on Einstein
This OLogy activity challenges students to find nine inventions that Einstein's ideas helped to create. The activity begins with an illustration of Al's Junk Shop. Mixed in with his junk are a Global Positioning System, CD player, computer, calculator, scanner, laser pointer, TV, and representations of both laser surgery and nuclear energy. After making a mental list of their nine choices, students can click to a second page to check their answers. Each invention has a rollover note about how Ei
Symptoms of Posttraumatic Stress Disorder in a New Orleans Workforce Following Hurricane Katrina
On August 29, 2005, Hurricane Katrina made landfall resulting in catastrophic damage and flooding to New Orleans, LA, and the Gulf Coast, which may have had significant mental health effects on the population. To determine rates and predictors of symptoms consistent with a diagnosis of posttraumatic stress disorder (PTSD) in New Orleans residents following Hurricane Katrina, we conducted a web-based survey 6 months after Hurricane Katrina made landfall. Participants included 1,542 employees from
This NASA site explains the three major types of atmospheric aerosols - volcanic emissions, desert dust, and anthropogenic aerosols - and how they affect global climate. The site discusses the generation and atmospheric distribution of these aerosols, as well as the chemical and physical processes by which they create global cooling.
This site features Java Applet, QuickTime, and Flash animations that illustrate characteristics and functions of the atmosphere. They show how atmospheric temperature, pressure, and density change with respect to changing altitude, the way different kinds of radiation (x-ray, ultraviolet, visible, and infrared) act in various levels of the atmosphere (troposphere, stratosphere, mesosphere, and thermosphere/ionosphere), how oxygen gas and chlorofluorocarbons (CFCs) interact with ultraviolet radia
Based on UNICEF's annual flagship publication, The State of the World's Children report (SOWC), the U.S. Fund for UNICEF has developed and released these free resources for educators to use with students in grades 3-12. The lesson plans and resources in these units are designed to be used sequentially or separately. Topics include addressing global affairs issues such as the Millennium Development Goals, real life stories from youth, the causes of childhood exclusion, and water and sanitation.

Globalism: Report from the Front Lines of Oil and Global Warming
Ben Namakin, an environmental educator from Micronesia, runs The Green Road, a mobile environmental awareness program focusing on upland watershed, mangroves, coral reefs, and waste and pollution. Using photography and film footage to talk about his experiences, Namakin will address global warming, environmental racism, and the influence of oil companies on political decision-making. He will particularly focus on how these consequences affect the cultures and lifestyles of Pacific Islanders. In
Global Competition: How We Can Win
6th Annual Berkeley in Silicon Valley Symposium In his recent best selling book, The World is Flat: A Brief History of the Twenty-first Century, Pulitzer Prize-winning author Thomas Friedman writes that the lowering of trade and political barriers and profound technological advances in global connectivity have enabled a "flat world" where it is possible to do business or almost anything else instantaneously and with billions of people. According to Dean Richard Newton, it is perhaps ironic that
The reasons for attrition
This paper focuses on a) to reflect on an approach, decisions and subsequent knowledge with regard to non response and b) to discuss the "attrition survey", rather than discussing the actual results of an overall longitudinal study. This should be linked to the paper "student experiences of enterprise education"
Dan Rather: Is the Media Failing in America?
A San Francisco Chronicle Herb Caen Lecture featuring Dan Rather, who was anchor and managing editor for the CBS Evening News for 24 years, and now serves as a correspondent for 60 Minutes and hosts and produces long form programming examining major global topics and events for the Discovery Channel, will be in conversation with Orville Schelll, Dean of the Graduate School of Journalism. Often referred to as "the hardest working man in broadcast journalism," Rather lives up to the description.
Changing the Culture of the Academy: Toward a More Inclusive Practice
Mission Statement Changing the Culture of the Academy explores ways that the academy might incorporate the challenge of diversity as it pertains to its core mission and practice. Participants will consider new paradigms for rethinking the academy that are inclusive of various cultural and disciplinary traditions, learning styles and identities. This will include opening a dialogue about these issues across all disciplines, from the social sciences and humanities to the physical and life sciences
Glow: Living Lights
This 48-page Teacher's Guide accompanies the "Glow: Living Lights" exhibit at the San Diego Natural History Museum. In PDF format, the guide contains 12 lesson plans that explore the chemical compounds and adaptations of bioluminescence, symbiosis, fireflies and other "glowing" terrestrial animals, dinoflagellates, ocean submersibles, blue vs. bright red light, the organization of life, defense, mating, and predator/prey mechanisms of bioluminescent organisms, human applications, and potential r
Components of the Earth System Working Together
The purpose of this resource is to develop familiarity with interactions among the major components of the Earth system at the global scale. Students brainstorm about the nature of connections between their region and others, across oceans and on different continents. On a black-line map of the world, they trace possible pathways of water and wind currents from their part of the continent to other continents, and identify what the wind and water carry. Then they write about the possible effects
Connecting the Parts of the Study Site
The purpose of this resource is to help students articulate and integrate their existing knowledge about the air, water, soil, and living things by viewing them as interacting parts of a system. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the ch
