All tunas are bad

Too much mercury. If you must eat tuna, maybe yellowfin tunas are less dangerous to eat, because they're caught younger so they have accumulated less mercury in their bodies. But then do you eat more of them to satisfy your appetite? If you do, the same amount of harm is done. Just avoid tunas.

New "golden" ratios for facial beauty

January 2010 issue of "Vision Research" has an interesting paper:
New "golden" ratios for facial beauty. If you look at these faces (source from their article):



don't you think the two in the black frames look better? That's because, as the researchers find out, given a specific person, i.e. not comparing one person with another, there is something you can do to beautify yourself. Specifically, when the vertical distance between the line connecting two pupils and your mouth is 36% ("length ratio") of the distance between the lower edge of the frontal hair and the chin, the face looks the most attractive. Similarly, a most attractive image is achieved when the distance between the pupils is 46% ("width ratio") of the face width (measured between inner edges of ears). Since both widths can be controlled with hairs, these findings should be exciting news for people seeking natural beauty.
