Researchers discover what makes men men
Researchers have isolated a genetic switch that separates the boys from the girls.
It turns off the female in the human embryo and starts biological changes that eventually puts hair on the chest.
Weiss said that science had long known that everybody at conception is female, but the precise biological mechanism that changes an embryo to male still is incompletely understood. Solving the puzzle on a molecular level may answer questions about other basic cellular changes, such as the development of cancer.
Michael Weiss of the University of Chicago said that the new study advanced the understanding of the complex cascade that determines whether people are male or female and that it shed new light on how this process sometimes could go awry.
WASHINGTON Cleaner fuel will cost money
In research published today in the journal Science, Weiss and his team use sophisticated imaging techniques to explore on an atomic level the biological pathway to manhood. Their research report traces the development of maleness, from the turning on of the SRY gene, which is on the Y chromosome, to the work of another gene, called MIS, that removes the female parts of the original embryo.
"If we can understand the switches involved in sex determination, then we could possibly relate that to other basic processes, such as how organs differentiate or how cancer arises," he said.
The December forecast for millions of Americans in the most polluted cities — better air, higher prices for gas.
Drivers will begin paying more as gasoline stations shift to a cleaner-burning but more-expensive fuel under government orders. Prices at the pump could rise a nickel or more a gallon.
By the end of the year, nearly one-third of all the gasoline sold in America will have to be a new, reformulated blend that the government estimates will produce 20 percent less toxic and smog-causing pollution.
But Berman voiced concern that retail gasoline prices may rise more than necessary in the confusion surrounding the introduction of the new fuel, which the Environmental Protection Agency estimates will cost refiners about 4 cents more a gallon to produce.
"This is the biggest change in gasoline in our lifetime," said William Berman, environmental affairs director for the American Automobile Association.
The change is expected to affect more than 48 million motorists in all or parts of 17 states, including the Northeast and mid-Atlantic regions from southern Maine to Virginia.
Rap star convicted of sex abuse
NEW YORK
Rap star Tupac Shakur was found guilty yesterday of sexually abusing a woman he had invited to his hotel room and was acquitted of more serious sodomy and weapons charges.
Shakur, 23, who was shot five times during a robbery Wednesday, was not in the courtroom when the verdict was read. He had appeared earlier yesterday in a wheelchair, but his lawyer said he had returned to the hospital.
The jury, which reached its decision on the third day of deliberations, found the same verdict for a co-defendant, Charles Fuller.24.
Each man was convicted of three counts of first-degree sex abuse, which means they groped and touched the victim without her consent.
"We're ecstatic," said Shakur's lawyer, Michael Warren. He said he was pleased that the jury kept an open mind.
ATLANTA
impotence linked to smoking
Smokers are 60 percent more likely to suffer from impotence than nonsmokers, the government said yesterday.
Researchers at the Centers for Disease Control and Prevention said the rate might be even slightly higher because their study was based on men willing to acknowledge the sexual disorder.
"It's more bad news for smokers,"said Dr. David Mannino of the CDC's National Center for Environmental Health.
Researchers estimate that up to 10 million U.S. men are impotent and that half of those cases are caused by such factors as diet, diabetes, aging, alcohol and medication. Smoking had long been suspected.
The study was based on a survey of 4,462 U.S. Army veterans between the ages of 31 and 49. Of that number, 1,162 said they never had smoked; 1,292 said they were former smokers, and 2,008 said they smoked.
KOUROU, French Guiana European rocket crashes into ocean
technicians at the Arianespace launching pad on the edge of the South American jungle said that the third-stage engine inexplicably lost pressure 135 miles above Earth.
The crash was the seventh in 70 launches since the commercial European Space Agency rocket program lifted off 15 years ago and became the world's most successful launcher of lucrative private satellites.
An investigation was opened immediately and a news conference scheduled for today to explain the initial findings.
