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."

Animals have an astonishing ability to develop reliably, in spite of variable conditions during embryogenesis. New research published this week  addresses how living things can develop into precise, adult forms when there is so much variation present during their development stages. A team led by John Reinitz at Stony Brook University, and funded by the National Institutes of Health, shows how fruit fly embryos can "forget" initial incorrect versions of their body plan and develop into recognizable adult flies.

Having a bad 2009?  It's only going to get worse when those printing presses they use to make more money finally break down.   But there is always a bright spot on dark days; babies.
