Inside the Collections: Ichthyology at AMNH
In the first of a new series of behind-the-scenes looks at the collections at the American Museum of Natural History, Melanie Stiassny, Axelrod Research Curator in the Department of Ichthyology, takes us through the Museum's vast collection of fishes. The Department of Ichthyology, one of the four departments within the Museum's Division of Vertebrate Zoology, houses a collection that comprises more than 2 million specimens from around the world, with a special focus on African, Australian, Ce
The Oil Spill's Other Victims (Science Bulletins)
http://amnh.org/rc10 Beyond oil-coated pelicans, the Gulf spill imperils many lesser-known species such as marsh grasses, seaweed, and deep-sea invertebrates. The latest Bio Bulletin from the Museum's Science Bulletins program highlights these unsung but critical components of Gulf ecosystems and features recent shoreline and surface oil maps from the National Oceanic and Atmospheric Administration (NOAA). View the story in AMNH's Hall of Biodiversity until July 23, 2010 or online. Science Bul
Authors@Google: Matt Ridley
In this clear-sighted book, Matt Ridley demonstrates that the world is getting better, and at an accelerating rate: food, income and lifespan are up; disease, child mortality and violence are down?all across the globe. Necessities and luxuries alike are getting cheaper; population growth is slowing down; Africa is following Asia out of poverty; the internet and the mobile phone are enriching people's lives as never before. The pessimists who dominate public discourse insist that we will soon rea
Conservationists@Google: Sea Shepherd Society
Established in 1977, Sea Shepherd Conservation Society (SSCS) is an international non-profit, marine wildlife conservation organization. Our mission is to end the destruction of habitat and slaughter of wildlife in the world's oceans in order to conserve and protect ecosystems and species. Sea Shepherd uses innovative direct-action tactics to investigate, document, and take action when necessary to expose and confront illegal activities on the high seas. By safeguarding the biodiversity of our
1.5 Water power This second phase was achieved by focusing on the water-power potential of the site. Water power had been the catalyst for the original industrial development, and it seemed apt to capitalise on that. It was decided to install a new waterwheel where the original one had been. This provided an important visitor attraction, and also presented the opportunity to use the waterwheel to generate electricity for the site, thus providing significant cost savings. Furthermore, as part of that building

1.4 The economics of maintaining a heritage site The National Trust operates within a complex web of funding. This comes from annual membership fees and from visitor receipts at individual sites. Each National Trust property is responsible for raising the income necessary to fund its own conservation activities and further development (although a large minority of sites cannot cover their costs). Properties raise this income through visitors charges and from catering, shop sales, etc. Failure to raise sufficient income can lead to job losse

Exoplanet Properties Activity
An astrobiology activity meant to be done in a 3 hour laboratory session (or possibly over 2-3 class sessions). The students work in groups to analyze the radial velocity curve of the star HD4308 which wobbles with a 15.56 day period. In the end the students determine if the planet which is causing this wobble is likely to support life similar to Earth on its surface. The activity draws on concepts such as Kepler's law, momentum conservation, the habitable zones around stars, spectral class, esc
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer provides the student with a real rock sample to observe and describe, helping the student notice that rock is composed of different combinations of minerals.
The Second Law and Energy (Panel)
In this valedictory panel to the two-day symposium, 10 speakers offer brief takes on how the Second Law of Thermodynamics might prove useful in seeking answers to our current energy challenge.
Even before the oil embargo of 1973, Thomas Widmer recalls, Joe Keenan and his MIT colleagues wrote of an “entropy c
Metro Life Flight Helicopter Visits Kent State
Metro Life Flight, the first air medical program in the area, had one of its helicopters visit Kent State University on Oct. 22, landing on the University Esplanade. After a nearly yearlong planning process, Kent State's College of Nursing and the MetroHealth System have collaborated to now offer clinical experiences aboard Metro Life Flight to Kent State graduate nursing students in the acute care nurse practitioner concentration.

The Man that Don't Fit / Robert Service
This two-minute reading of this famous poem shows the power of the words of the poem as well as the importance of reading it well. The words are played over the screen and should appeal to a variety of students. Delivered by Boucrate in 2010.
Why Species are Fuzzy
The ‘species concept’ – the definition of what constitutes a distinct species – has been a headache for biologists for at least 70 years. Recent genetic studies in natural populations have led to a revolution in the understanding of biodiversity and speciation. Species are demonstrably continuous with subspecies and varieties in nature, and intermediates in the speciation process are all around us. I will illustrate my talk with examples such as butterflies, birds and even whales. Lectu

24. Population and the Environment
Global Problems of Population Growth (MCDB 150) World population will continue to rise until at least 2050. Environmental impact is the product of the number of people and how much of their income and technology is devoted to either consumption or conservation. So far, the balance is far at the consumption end and, globally, environmental problems are increasing. Environmentalism has not come close to counteracting the footprint of a billion extra people every dozen years. The only massive succ
