More information for the nature vs nurture debate... We know, for instance, from observations of both humans and nonhumans that males are more aggressive than females, that young males engage in more rough-and-tumble play than females and that females are more nurturing. We also know that in general males are better at a variety of spatial or navigational tasks. How do these and other sex differences come about? Much of our information and many of our ideas about how sexual differentiation takes place derive from research on animals. From such investigations, it appears that perhaps the most important factor in the differentiation of males and females and indeed in differentiating individuals within a sex is the level of exposure to various sex hormones early in life.

Finally. In case you haven't heard... Mozilla is the free, non-monopolistic, standards-compliant, platform-independent browser. Now officially released. I've deleted MSIE from my (Apple) computers, thus getting one step closer to being completely Microsoft-free. If some organisation's website is incompatible with Mozilla, they'll immediately lose my business. 

tips for busy people. You'll laugh and some are silly perhaps... There are tons of tips one could list. I'm sure each individual develops his own collection of tricks, adapted to personal habits and experience. For instance, in the realm of going abroad: bring a second wallet to store the "other" currency; find out in advance what tipping is standard, if any; know how to say "no thanks," "NO!" and "leave me alone." 

Next, Sweden needs to tie or defeat Argentina. Sverige vann den viktiga matchen mot Nigeria i fotbolls-VM med 2-1. Henrik Larsson gjorde Sveriges båda mål. Sverige har nu fyra poäng och leder gruppen före England som har lika många poäng efter lagets seger med 1-0 över Argentina. [Svenska Dagbladet]
