SUMMARY – These are some key discoveries described in Science magazine, which covers the headline discoveries in all fields of science. You can also find Science at most public libraries.

More evidence that happy thoughts are important to good nutrition of the mind – Analyses of brain activity reveal a link between social and physical pains and pleasures. Science 13 February 2009: Vol. 323. no. 5916, pp. 890 – 891

Being optimistic improves performance – Findings suggest that because initial psychological states and performance determine later outcomes by providing a baseline and initial trajectory for a recursive process, apparently small but early alterations in trajectory can have long-term effects.Science 17 April 2009: Vol. 324. no. 5925, pp. 400 – 403

Old age not for pessimists – Healthy adults under 50 described their views of old age as positive or negative. About 40 years later, 20% of those looking forward to maturity had had heart attacks, compared to 70% of those with a negative view. Score another one for positive psychoneuroimmunlogy.Science 10 April 2009:
Vol. 324. no. 5924, p. 155

Female company helps men stay healthy – Reproductive aging in men is evidenced by decreased fertility that correlates with decreased testosterone and sperm motility. ..Reproductive aging is delayed when females are present, and this delay represents a 20% extension of the normal period of fertility. Science 13 February 2009:
Vol. 323. no. 5916, p. 854

BCAAs promote fertility – If you want to get pregnant more easily, have your physician discuss with you this article on how BCAAs activate eggs to be ready for fertilization. [I hypothesize it may increase male sperm count as well]. Science 24 April 2009:Vol. 324. no. 5926, pp. 476 – 477

I HOPE THE WEATHER IS WONDERFUL IN YOUR PART OF THE WORLD. PLEASE HELP YOUR FRIENDS OPEN THEIR EYES TOO!
