Happy Birthday Mama Barbara Bush...


How time passes differently as you get older... "Kuzeeka"


Becoming an adult, of course, alters many of our ideas about time. We get used to its relativity - the fact that a migraine seems to last for decades, while fun with a loved one burns away like a half-inch fuse. We perceive our memories differently as we age. I've been told that last year's summer when I was five seemed long as a mission to Mars, because it was such a large proportion of my lived time at that point, while last year's summer today seems to have involved one stroll in the country and planting some strawberries. I'm pretty sure I also wasn't paying that much attention to last summer, because I was busy and summers had happened to me before.

Crowe's 'whitewashing' sparks criticism from advocates

Hollywood's reliance on bankable - and often white - actors has led to another round of sharp criticism of filmmakers for "whitewashing" roles where race and ethnicity play a part.
In Aloha, Cameron Crowe's latest film, Emma Stone, a American actress with blonde hair and green eyes, was cast as Allison Ng - a junior fighter pilot who was part-Chinese, part-Hawaiian and part-Swedish.
Soon after the release, there was an uproar of criticism from social media against Crowe's casting choice. Both Asians and non-Asians asked why they didn't pick an Asian actress to play a character who is part-Asian.
One advocacy group called Aloha "a whitewashed film" that failed to portray the ethnical diversity of Hawaii. The Media Action Network for Asian Americans (MANAA) noted 60% of Hawaii's population is Asian-American Pacific Islanders and 30% Caucasian, a fact not reflected in the film.

How 1970s deodorant is still doing harm...

Fluorine is an evil gas. And it is also used to manufacture a string of other artificial gases, some of which nearly left mankind exposed to burning ultraviolet light - and are even now warming the planet.
"Fluorine is the tyrannosaurus rex of the periodic table," says chemistry professor Andrea Sella. "It will react spontaneously with every other element except for helium, neon and argon."
If you ever happen to lay eyes on pure, elemental fluorine, it looks fairly innocuous - a pale yellow gas - but in truth it is so dangerous that Sella's department at University College London does not even keep it in stock.
It produces a smell similar to chlorine, he says, "but generally, if you smell fluorine what you do is run away as fast as you can".
Sella does have a jar of another frightening material - hydrofluoric acid or HF. Its acidity - that is, the reactiveness of the hydrogen ions it contains - is not actually quite as strong as that of the better known hydrochloric or sulphuric acids.
But it is nonetheless an exceptionally vicious chemical, because the ferocious fluorine ions can penetrate deep into your body. "It's an unbelievably painful burn, and one that you cannot really treat, because it's gone inside," says Sella.
Once inside, the fluoride gobbles up the body's calcium, which can lead to heart failure in extreme cases.
