Permafrost science

We discussed the arctic tundra in class as a biome. These scientists are looking into the permafrost and what possibly could happen if large amounts of it 'defrost' in the coming years. It seems that they are worried about the amount of methane and carbon dioxide that could be produced.

Comment on the the ecology of the biome and how heating up the permafrost could affect the entire ecosystem. AP Biology students might also want to focus on the positive feedback look that is mentioned in the article. Lastly, determine whether this is valid science and worthy of the money invested by the Department of Energy

DNA in a cup of water?

Biodiversity is difficult to measure, especially in aquatic settings. There is a new technique, much like one described in an earlier blog post where scientists tested the DNA found in the soil. In this technique scientists take a water sample from a body of water can find the biodiversity. It's an interesting technique.

What do you think the benefits of this would be? What are some drawbacks? When you're answering, think in terms of the scientific method.

Stereotypes: Women like fruits and vegetables, men like meat

The American Society of Microbiology has made a huge step forward in the differences in diet between the human genders. They determined that males prefer meat and poultry while females prefer fruits and vegetables. While this seems like identifying that water is wet, it might also be very good for following food poisoning cases. Do you fit in with this study's findings?

Pride and Arsenic? Arsenic and Sensibility?

Was Jane Austen's death caused by arsenic? While classic English literature is usually out of the scope of science class this article identifies how some scientists are investigating the death of Jane Austen. If you comment, also identify your favorite Jane Austen book or movie from the book (if you have one). I watched a movie variation of Pride and Prejudice based in India call edBride and Prejudice. It was interesting.

What causes a muscle cramp?

Football cramps are a mainstay of August and September football games. Their cause remains a mystery to scientists. There are plenty of hypothesis, and some new (circa 2002) ideas about their causes.

AP Biology and anatomy students, read through and identify the new ideas and how they fit in with the maintenance of homeostasis. All students can read through and propose ideas for studying these cramps. What conditions would be necessary? How valid would any study be? What could coaches do to avoid these cramps during the early season games.
