Who hasn't tried to bleach their hair with hydrogen peroxide  in college?    I can't tell you how many young scientists we know who tried to go for that young Reed Richards look.

It turns out that hydrogen peroxide may be responsbile for bleached hair in aging also, though not intentionally.   

Researchers of the Johannes Gutenberg University Mainz in Germany nd the University of Bradford  say they have now unlocked the secret of hair turning white or gray in old age. According to them, free oxygen radicals are significantly involved in the loss of hair color.

Sulfuryl fluoride, a gas used for fumigation, has the potential to contribute significantly to future greenhouse warming, but because its production has not yet reached high levels there is still time to nip this potential contributor in the bud, according to an international team of researchers.

Their study of  sulfuryl fluoride this month in the Journal of Geophysical Research, measured the levels of the gas in the atmosphere and determined its emissions and lifetime to help gauge its potential future effects on climate.
If you want to perform at your peak, you should carefully consider how you discuss your past actions. In a new study in Psychological Science, psychologists William Hart of the University of Florida and Dolores AlbarracÃn from the University of Illinois at Urbana-Champaign reveal that the way a statement is phrased (and specifically, how the verbs are used), affects our memory of an event being described and may also influence our behavior.
Polymorphisms are variations in genes which can result in changes in the way a particular gene functions and thus may be associated with susceptibility to common diseases.

In a new study in Psychological Science, psychologist Tina B. Lonsdorf and her colleagues from the Karolinska Institutet in Sweden and the University of Greifswald in Germany examined the effect of specific polymorphisms on how fear is learned and how that fear is subsequently overcome.
You might think that predicting eye color is easy because we all learned in high school about recessive genes and eye color is a great example of those.    But it isn't easy.  In fact, human eye color, which is determined by the extent and type of pigmentation on the eye's iris, is what geneticists call a 'complex trait,  meaning that several genes control which color the eyes will ultimately have. Over the past decades a number of such 'eye-color genes' have been identified, and people with different eye color, will have a different DNA sequence at certain points in these genes. 
There's no question that employees at Fermi National Accelerator Laboratory have watched with some concern as the LHC got all the press about being the future of physics despite the fact it hadn't actually produced anything.    They have also quietly continued setting world records and are once again reminding people that Fermilab's Tevatron, currently the world's most powerful operating particle accelerator, is actually ahead, even in the race to find the as-yet undefined "Higgs particle."
