Links for the week of February 26th, 2010

If you want to follow my shared links in real time instead of as a weekly digest, head over to Delicious. You can search them there easily too.

  • The truth about risk – A great interactive info-graphic and discussion for exploring various investment returns over the last century.
  • The American poor spread to suburbia, but we’re not ready – We already have a word for a large annulus of poor people surrounding a relatively wealthy urban core, and it's not "suburbs". For instance, we don't talk about the "suburbs" of Jakarta, or Mexico City, or Cairo, or Nairobi.
  • Enceladus' Warm Baghdad Sulcus – Thermal IR overlaid on a visible light mosaic of Baghdad Sulcus on Enceladus. Basically the whole fracture is warm and spewing geysers into space. Weird weird awesome icy place.
  • The Case For An Older Woman – No surprise: men disproportionately prefer younger women, but it turns out women are fairly even-handed when it comes to age and dating. However, if you look at many other preferences (sex frequency, dominance/submissiveness, etc.) younger men and older women actually aren't a bad match. I certainly don't regret having had experiences with older women when I was younger.
  • Attribution of climate forcing to economic sectors – A paper in PNAS on relative climate effects of different industry sectors, which emit different relative proportions of aerosols (cooling) and GHGs (warming). Cars are "clean", and so are almost exclusively warming both short and long term. Power is "dirty", and so is less warming short term. However because the time-constants for removal of aerosols and GHGs are so different, in the long term, all these emissions are warming. Suggests cutting out car emissions first, then going for power/industry, lest we also remove our inadvertent sulfate aerosol geoengineering. Interesting way of looking at the problem, but I fear it will be latched on to by the deniers/geoengineers and misconstrued to suggest that dirty emissions are actually a good thing…
  • Caltech Symposium on African Health – A talk by Bruce Hay on his Medea gene complex, which allows one to drive a transgene aggressively into a wild population. In this case, the target population is mosquitoes, and the gene to drive is one that makes them incapable of carrying malaria (or yellow fever, or dengue fever, etc.).
