Tracking Illegal Fishing-From Space - YouTube - 0 views

  •  
    3:16 video To track commercial fishing activity around the world, SkyTruth, a small nonprofit based in Shepherdstown, West Virginia, has recently launched Global Fishing Watch in partnership with Google and Oceana. This prototype tool analyzes a satellite-collected feed of tracking data from ships' automatic identification systems-which vessels use to communicate their location to one another-to map movement over time and automatically determine which ships are engaged in fishing activity. Each vessel is pinpointed on a map outlining fishing laws around the globe. This map will be publicly available on theWeb, allowing anyone with an Internet connection to act as a watchdog and see when and where commercial fishing activity is occurring.

Drug Wars: An Epic Tale of Asthma and Bacterial Pneumonia - National Center for Case St... - 0 views

  •  
    This integrative case study is based on real events that the author experienced with her ten-year-old daughter. Although the names have been changed, all of the events (symptoms, diagnoses and treatments, types of healthcare professionals) are recorded exactly as they occurred. Both asthma and pneumonia are common in the United States (and globally). Many of the drugs described in the case study are frequently prescribed for a wide variety of ailments. The four "episodes" that constitute the case cover 1) a study of asthma triggers, incidence and treatment; 2) side effects and possible medication errors associated with steroids; 3) causes, diagnosis, treatment and prevention of community-acquired bacterial pneumonia; and 4) the mechanism of action of two different antibiotics. The "epilogue" explores a few larger themes related to healthcare and public health (e.g., continuity of care, drug resistance, asthma prevention programs). The case study could be used in an undergraduate, upper-level, infectious disease, microbiology, public health or physiology course or in a graduate-level health professions program.

Are earthquakes also earth burps? | Science/AAAS | News - 0 views

  •  
    An "excuse me" might be nice. Researchers have found that Earth belches a potent greenhouse gas known as tetrafluoromethane (CF4) during earthquakes and other tectonic events. The emissions likely aren't making a significant contribution to global warming, but the findings could change the way scientists model future climate scenarios. They also complicate the use of CF4 as a way to measure how the continents and climate have changed over millennia.

The Nitrogen Cycle: Processes, Players, and Human Impact | Learn Science at Scitable - 0 views

  •  
    Nitrogen is one of the primary nutrients critical for the survival of all living organisms. Although nitrogen is very abundant in the atmosphere, it is largely inaccessible in this form to most organisms. This article explores how nitrogen becomes available to organisms and what changes in nitrogen levels as a result of human activity means to local and global ecosystems.

Wrap-up: U.S. Senate agrees climate change is real-but not necessarily that humans are ... - 0 views

  •  
    Nearly all U.S. senators agreed today on a measure affirming that climate change is real and not a hoax-including, to the surprise of many observers, Senator James Inhofe (R-OK), the man who once declared global warming a hoax. Meanwhile, although two other measures stating that humans are contributing to climate change won a majority of votes from the 99 senators present, they failed to garner the 60 votes needed to be adopted by the Senate.

WHO | Vector control and insecticide resistance - 0 views

  •  
    Vector control is a fundamental element of the existing global strategy to fight malaria. Vector control interventions have a proven track record of successfully reducing or interrupting disease transmission, particularly in areas that are highly prone to malaria. Indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs) are the two core, broadly applicable malaria vector control measures. This section covers both core and supplementary vector control methods and discusses the action that is required to prevent and manage the increasing challenge of malaria vector resistance to insecticides.

NSTA Learning Center - 0 views

  •  
    SciGuides are a collection of thematically aligned lesson plans, simulations, and web-based resources for teachers to use with their students centered on standards-aligned science concepts. Human modifications to communities of living organisms in an ecosystem can change the function and processes of that system. The flow of energy through an ecosystem depends upon the diversity of organisms within it; therefore, when this flow is altered, substantial biological and geological changes occur. It is important that our students not only realize that when a local ecosystem is destroyed or negatively affected by human transformations (building, agriculture, technology); the effect is eventually felt globally. We cannot ignore the fact that everything we do impacts our natural environment. The main question is, "How can we be better "keepers of the Earth"?

Biotech Foods are Safe. Says Who? [INFOGRAPHIC] - 0 views

  •  
    Biotech foods ('GMOs') are safe. Period. That may seem like a bold statement, but it comes with the weight of a huge body of research and global consensus among preeminent health organizations. To understand the safety of food biotech, it helps to look at the numbers. There are thousands of studies on biotech crops published, billions of pounds of biotech foods eaten, and there are zero illnesses (human or animal) resulting of consuming biotech foods.

High Tech High: Ebola: Going Viral - 0 views

  •  
    In the wake of a potential global crisis we will investigate the biology of infectious diseases to better understand how they transmit, replicate and induce an immune response in humans. Our objective is to pose solutions to the Ebola outbreak in the United States by studying other infectious diseases. We will investigate infectious diseases and the development of vaccines to show how they have changed the course of human health and populations as a whole. We will determine public perceptions about infectious diseases and identify misconceptions. Ultimately, we will develop community awareness information to manage and in future prevent an outbreak of Ebola.

AP test: Rio Olympic water badly polluted, even far offshore - Yahoo News - 0 views

  •  
    In July, the AP reported that its first round of tests showed disease-causing viruses directly linked to human sewage at levels up to 1.7 million times what would be considered highly alarming in the U.S. or Europe. Experts said athletes were competing in the viral equivalent of raw sewage and exposure to dangerous health risks almost certain. The results sent shockwaves through the global athletic community, with sports officials pledging to do their own viral testing to ensure the waters were safe for competition in next year's games. Those promises took on further urgency in August, after pre-Olympic rowing and sailing events in Rio led to illnesses among athletes nearly double the acceptable limit in the U.S. for swimmers in recreational waters.

The Polar Bear of the Salt Marsh? - National Center for Case Study Teaching in Science - 0 views

  •  
    Polar bears are an iconic symbol of climate change, but regionally relevant examples of susceptible biota are needed to highlight how global forces impact local environments. In this interrupted case study, students follow a young naturalist as she explores why saltmarsh sparrows are increasingly rare in coastal wetlands of the northeastern United States. In small groups, students diagram how sea-level rise may alter saltmarsh sparrow habitat and analyze a graph to determine if there is evidence to support sea-level rise. The social implications of rising sea levels induced by climate change can also be explored with an optional jigsaw activity. Students who successfully complete this case study will integrate key concepts related to sea level rise, interpret scientific data and draw conclusions about environmental change, and evaluate alternative management decisions. Originally developed for an undergraduate ecology course, the case could easily be adapted by college or high school instructors for an introductory biology or an environmental science course.

The Demise of the Forest People - National Center for Case Study Teaching in Science - 0 views

  •  
    In this case study, the complexity of the Malaysian palm oil industry is examined through the perspective of various stakeholders, namely, villagers, corporations, orangutans, smallholders, conservationists, and an average consumer. Students learn about the plight of the orangutan and the environmental impacts of the palm oil industry but also understand the influence of global markets and the effect of their own purchases. Students are challenged to make ethical decisions, propose policy recommendations, and examine their own contributions to the demand for palm oil. The aim of the case is to provide students with tools to personally champion change. The case is appropriate for undergraduate students in wildlife, ecology, biology, or related classes but can also be tailored for advanced high school science courses.

Mad Dogs and Chicken Heads - National Center for Case Study Teaching in Science (NCCSTS) - 0 views

  •  
    Although rabies still causes thousands of deaths globally every year, it has essentially been eradicated from most industrialized countries. Part of the success story is due to an unusual project undertaken by the Swiss prompted by a series of large outbreaks in the 1970s: the large-scale vaccination of wild foxes to stop the epidemic. In this directed case study, students use an easily accessible MS Excel-based model to understand key epidemiological parameters of rabies outbreaks in wild foxes. The simple model allows students also to predict what proportion of foxes needs to be vaccinated to eradicate the virus from the population. The case fits into both ecological and microbiological (epidemiological) courses and offers opportunities to explore zoonotic diseases and "One Health" questions. The mathematical basis of the differential equations in the models is explained, although prior knowledge of calculus is not essential. A key learning outcome is the critical understanding of both the power and limitations of simple epidemiological models. This case was written for an online course but could also be used as a face-to-face activity if students have access to computers in class.

World population growth is expected to nearly stop by 2100 | Pew Research Center - 0 views

  •  
    For the first time in modern history, the world's population is expected to virtually stop growing by the end of this century, due in large part to falling global fertility rates, according to a Pew Research Center analysis of new data from the United Nations. By 2100, the world's population is projected to reach approximately 10.9 billion, with annual growth of less than 0.1% - a steep decline from the current rate. Between 1950 and today, the world's population grew between 1% and 2% each year, with the number of people rising from 2.5 billion to more than 7.7 billion.

A Fatal Bite - National Center for Case Study Teaching in Science (NCCSTS) - 0 views

  •  
    In this case study, students follow "Mr. Okoro" as he makes the long journey with his sick daughter "Ada" to seek medical attention at the nearest clinic in Enugu, Nigeria. It is the rainy season, and "Dr. Fabian" from the Division of Parasitic Diseases and Malaria has been called in to investigate a suspected outbreak of malaria. Students learn about the circumstances in Ada's background that may have led to her illness, and then adopt the perspective of Dr. Fabian as she investigates the outbreak. They consider the epidemiological triangle, the different stages of the Plasmodium parasite lifecycle and how it leads to malaria, and evaluate the broader societal factors and future implications of malaria in Sub-Saharan Africa. The case was designed for upper-level global health, public health, and human biology courses, but could also be adapted for general biology, health studies, infectious disease, and epidemiology courses.
