Eating bananas may influence sex of baby :: CHICAGO SUN-TIMES :: Nation (Science/Technology, 4 articles)

CHICAGO - Snips and snails and puppydog tails... and cereal and bananas? That could be what little boys are made of, according to surprising new research suggesting that what a woman eats before pregnancy influences the gender of her baby. April 23, 2008 Eating a good breakfast dramatically increases a woman's chances of having a son rather than a daughter, a surprising new study has found. The findings, by scientists at Oxford and Exeter universities, adds a new twist to the familiar cereal slogan " Kid tested. Having a hearty appetite, eating potassium-rich foods, including bananas, and not skipping breakfast seemed to raise the odds of having a boy. The British research is billed as the first in humans to show a link between a woman's diet and whether she has a boy or girl. Among women with the highest calorie intake before pregnancy (but still within a normal, healthy range), 56 percent had boys, versus 45 percent of the women with the lowest calorie intake. Women who ate at least one bowl of breakfast cereal daily were 87 percent more likely to have boys than those who ate no more than one bowlful per week.

Tests Confirm T. Rex Kinship With Birds (Science/Technology, 4 articles)
|
Bits of protein obtained from connective tissues in a T. rex fossil show a relationship to birds including chickens and ostriches, according to a report in today's edition of the journal Science. In the first analysis of proteins extracted from dinosaur bones, scientists say they have established more firmly than ever that the closest living relatives of the mighty predator Tyrannosaurus rex are modern birds. The research, being published Friday in the journal Science, yielded the first molecular data confirming the widely held hypothesis of a close dinosaur-bird ancestry, the American scientific team reported.

By JASMIN K. WILLIAMS January 17, 2008 Today's page looks at one of the world's favorite foods - chocolate. CHOCOLATE comes from the cacao tree, which was discovered more than 2,000 years ago in the tropical rainforests of Mesoamerica, a region that extends roughly from Honduras to Mexico. The cacao seeds were mixed with spices, water and cornmeal to create a frothy but bitter drink - no sugar yet.

Raise the heat to medium high, then add the meat, a piece or two at a time, making sure that there is enough heat in the pan to brown all the meat. On a rimmed baking sheet lined with nonstick liner, buttered parchment or waxed paper, spread pepitas close together in a single layer 2. Continue to cook, tilting pan occasionally to distribute heat evenly, until a caramel of a deep amber color forms, about 15 minutes 3.

Creating clouds to ease global warming would harm ozone layer: study (Science/Technology, 4 articles)
|
Also out there: worldwide loss of rain forests, depletion of the ozone layer in the stratosphere, loss of species diversity, the solid waste crunch, acid rain, and more. This would delay the recovery of the Antarctic ozone hole by decades, and cause significant ozone loss over the Arctic, say US researchers. One potential drawback is that sulphates provide a surface on which chlorine gases in polar clouds can become activated, causing chemical reactions that lead to the destruction of ozone molecules.
