Dinosaur called Dakota - A Man With a PhD

A beautifully preserved dinosaur found in the US retains remarkable detail of skin cells.

Now this is really cool. The dinosaur's soft tissue was so well preserved and then replaced by minerals that its underlying structure was still maintained. So they could actually see cellular structure.

They could determine that the skin had two layers, just as expected by study of modern relatives of the dinosaur. They found that in regions of the dinosaur that had shown bite marks in previous fossils, the skin was much thinner explaining why predators would go for that region first.

Change science education - A Man With A PhD

chalkboard by Lee Nachtigal Science Teacher Retention: It Takes More Than Money: [Via AAAS News - RSS Feed] Science Teacher Retention: It Takes More Than Money
High school science teachers value control over their lesson plans and prestige in their school districts more than salary increases, according to a survey discussed at AAAS.

[More]

I am very willing to believe that it would be lot easier to retain science teachers if they did not have to put up with some of the control of curriculum by non-scientists or administrators. But then that really only happens because administrators do not really respect the science teachers.

So the two problems go hand in hand. But then, that is because our education system is based on an out-moded approach where finding and disbursing information is hard and must be carefully taught by authority figures.

Scorpions and frogs - A Man With A PhD

frog by noodlemaps

I discuss Paul Krugman's column on the
cynical ploys of so many Representatives in Congress at Path to Sustainable. In this case, their denialist views on climate change.

As I said, it reminds me of the
fable about the scorpion and the frog. This led me to a very interesting page about the ethics of the situation. In particular, it discusses the scorpion's response or defection, in the context of a real game, one with a definite end..

As the scorpion thinks, 'If the game comes to an end, then I need to get mine before that happens. I need to grab for as much of what is available NOW before the frog gets theirs.'

If there is no future, no shadow on the scorpion, then it might as well do what it wants and follow its nature. No future means it is free to defect from the beginning and never have to cooperate.

Since the scorpion will cynically defect and sting at the first opportunity (why wait until the end anyway?), the decision of the frog now becomes paramount. What should the frog do?
