Dear Jason,

If you like wild speculation as a starting point for research, here's a thought... since haemeoglobin carries iron in the blood, is it possible that blood provides some kind of inner sensor for magnetic North? One way to test for this would be to screen the direction-sensing abilities of many subjects with different levels of haemoglobin in their blood. Personally I don't think the theory works... I have high haemoglobin levels but a terrible sense of direction. One person is not a good test, statistically speaking, though the individual case can be a good starting point. As far as I know, the magnetisim-sensing system of birds has not yet been found in mammals.

Cheers, P.

Thanks.

I wonder if undergraduate students can take and share the idea of producing a class chemistry journal that records some of their class background, questions and findings. This could be started at the beginning of a course, be completed part way through, and then be discussed and analysed as a project at the end.

While some students might excel at layout, others might excel at questions,  others at providing answers based on class experiments, and others might be good editors.

The aim would be to give an opportunity for everyone to learn something, regardless of their starting level in the subject.
