Houdini Honey Badgers Can Escape From Anywhere So half the Internet has seen the video about what total badasses honey badgers are (reminder at bottom for those who want a second look). But they don't just have attitude. As this clip from a BBC documentary reveals, they're also really smart. We know a lot of people who wouldn't be able to work out how to get out of an enclosure like this. It is amazing to think that barely 50 years ago Jane Goodall was mocked for producing evidence that chimpanzees use tools. One can only imagine the response if she had made the same claims about honey badgers, whose relationship to us is many times more distant. Stop the Spread of Superbugs - NIH News in Health, February 2014 For nearly a century, bacteria-fighting drugs known as antibiotics have helped to control and destroy many of the harmful bacteria that can make us sick. But in recent decades, antibiotics have been losing their punch against some types of bacteria. In fact, certain bacteria are now unbeatable with today’s medicines. Sadly, the way we’ve been using antibiotics is helping to create new drug-resistant “superbugs.” Superbugs are strains of bacteria that are resistant to several types of antibiotics.
Nature adapts to Chernobyl Chernobyl: 28 years after disaster On April 26, Ukraine marks the 28th anniversary of the Chernobyl disaster, the worst nuclear accident in history. Take a look at haunting scenes from inside the exclusion zone. 25, 2014 Novoshepelychi, Ukraine: The clicking sound from Timothy Mousseau's radiation detector slowly increased as he walked through the forest here, a few miles west of the Chernobyl nuclear power plant. As he stopped to examine a spider web on a tree branch, the display on the device showed 25 microsieverts an hour.
Evolution: Library: Evolution of Camouflage In the insect world things are often not what they seem, especially if you're a hungry predator. For 250 million years, insects have survived because they often appear to be something other than what they really are. Is it a bug, a twig, or a leaf? Is that butterfly the bitter-tasting one, or the delicious one that resembles it? An astonishing number of insects have evolved survival mechanisms that involve mimicry, camouflage, and disguise. In the case of orange-and-black butterflies, the viceroy has evolved a striking resemblance to the beautiful but foul-tasting monarch. Darwin/Lamark court case By Don Mills This six to seven 40 minute period activity allows students to role play while learning theories of evolution. To start this activity have your students write their names on scrap pieces of paper. Read the list of roles to the class. After reading the roles to the class ask the members of the class interested in being the judge to place their names in a beaker then draw a name and return other names to their owners.
Evolution: Library: Tale of the Peacock At a singles cocktail party, the ending is often predictable. A female may choose a male from several because he is attractive. But why does she think he is good looking? Scientists, stumped by that question throughout the animal kingdom, hypothesized that something more than chemistry drives mate choice. Looks are certainly important for the peacock, with his absurdly bright, burdensome train that he shows off to attract a female. guppy The purpose of this activity is to analyze how guppy populations change over time. The simulation activity allows you to start with a pool of guppies and your choice of predators, you will be able to watch what happens to your guppy population and how the introduction of predators can affect the guppy's appearance. The simulation will help you understand what pressures drive guppy evolution.
Hands-on Activities for Teaching Biology to High School or Middle School Students by Drs. Ingrid Waldron and Jennifer Doherty, University of Pennsylvania The expression "hands-on, minds-on" summarizes the philosophy we have incorporated in these activities - namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts. Many of our activities are explicitly aligned with the Next Generation Science Standards, as indicated by (NGSS) in the descriptions below and the links to the right.

Evolution and Natural Selection Nature encourages no looseness, pardons no errors - Ralph Waldo Emerson I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection. Videos / What Was The Miller-Urey Experiment? - Stated Clearly Description This animation was sponsored by the Center for Chemical Evolution, NSF, and NASA: The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life.
The Zoo of You By Neil Shubin Posted 10.26.09 NOVA You may not feel much like a shark, fruit fly, or worm, but you share many aspects of your anatomy and physiology with these and all other animals on Earth. All the various bits and pieces of you–organs, bones, nerves, even your genes–show up in different but fundamentally similar forms in other animals, in some cases animals that lived half a billion years ago, revealing how all creatures on Earth, including you, are just variations on a theme. Launch Interactive Videos / What is Chemical Evolution? - Stated Clearly Description Have you ever wondered how life first got started on Earth? So do scientists! Though the question has not yet been fully answered, a careful study of Chemical Evolution is beginning to shed light on this mystery. In this film you will learn what Chemical Evolution is, how it works, and how it is different from Biological Evolution.
Who Evolved on First? Bud Abbott and Lou Costello While I was writing this post, I heard that Bill Nye and Ken Ham are planning to have a debate about evolution and creation. While it could be an interesting conversation, I suspect that it will suffer from the same communication problems that afflict most of these debates. Have you ever heard the brilliant comedy routine, “Who’s on first?” by Bud Abbott and Lou Costello? If not, you should listen to it before you continue reading.
