This link, sent by a fried (thanks FPJ) is really fascinating. When flowers bloom or close. Practical--not really--but interesting? Absolutely.

Yep. That's right The Periodic Table as you've almost never seen it before. Take a look--photographs of elemental vanadium! In-depth exposes of the noble gases. Far more than you ever wanted to know about Yttrium and Cesium!
Pay close attention to the Kelvin slider for loads of fun with gaseous silver! ('long about 2440 K)
I found this article interesting, informative, and compelling in an anecdotal sort of way, supporting observations I have made over the course of years and providing a little insight into what I have often seen as paradoxical and anti-scientific.
“It is reasonable to assume that persons with relatively high daily energy expenditures would be less likely to gain weight over time, compared with those who have low energy expenditures. So far, data to support this hypothesis are not particularly compelling.”
The question of weight gain would seem to be a simple physical equation--calories in>calories out--gain weight, calories in<=calories out--maintain/weight loss. But that hasn't been the experience of many in my acquaintance, and I have often wondered why. I become convinced that the implication of HFCS in weight gain has a compelling metabolic element to it. Does the addition of so much high-fructose corn syrup to the American diet actually promote obesity? Again, anecdotally and perhaps coincidentally, the evidence suggests that the answer may be yes. But how does one go about addressing the issue?
