- A recent issue of Nature (Oct 29) had a simple model of the prisoners
- dilemna with spatial stucture. A N*N (it varied) grid had a single
- player per square with a fixed strategy (cooperate or defect). Each square
- played each of the surrounding squares and the player with the highest
- score inherited the square. For some sets of parameters, both strategies
- remained on the board. Chaotic spatial patterns and kaliedoscopic
- oscillations could be seen under different starting conditions.
-
- There was also a paper documenting a new fossil link between birds
- and theropod dinosaurs. Wait, did I say link -- silly *&%^$^&%$
- me, I meant to say "evidence that two more links are needed"! 8-)
-
- There was also a paper with supporting evidence for the location
- of the K/T impact site (at Chicxulub, Mexico).
-
- Another cool paper dealt with strategies of behaviors in wasp
- societies and there was another one about mucking about with homeotic
- genes and getting stuff to grow in the wrong place in mice.
-
- And as if that weren't enough, fans of the old/new earth debate can
- check out a paper about deglaciation of Antarctica 3MYA and there
- is a also letter by Forest Mims III (remember him from the SciAm
- brouhahah?)
