Gov't to launch li0vestock tracking System will not include age of animals, despite importance of age in mad cow disease investigations WASHINGTON (AP) - A livestock tracking system planned by the govern- ment will not include the age of animals, despite the key role age has played in mad cow disease investigations. Agriculture Department officials say they don't want to overburden ranchers and can track most birth dates. Critics said the omission could make the system worthless. "So what's the point of having this animal ID system? This is one fact you actually really need to know when it comes to mad cow" Jean Halloran, director of food policy initiatives at Consumers Union, said yesterday. The department promised to create the system after the nation's first case of mad cow disease two years ago and has already spent $84 million on it. Earlier this month, Agriculture Secre- tary Mike Johanns promised it would be in place by 2009. The system also applies to pigs and chickens and to many other diseases. But the controversy is about mad cow disease, medically known as bovine spongiform encephalopathy, or BSE. "When you're dealing with conta- gious diseases such as foot-and-mouth disease or exotic Newcastle, age really isn't all that important," department spokeswoman Dore Mobley said. "It's important when you're talking about BSE, to estimate when an animal may have become infected." The goal is to allow authorities, within 48 hours after a disease is discovered, to pinpoint a single animal's movements. Industry groups are collecting and keep- ing the data, which the government intends to tap when there is an outbreak. Mad cow disease doesn't spread like the flu; scientists say it spreads only when cattle eat feed containing diseased cattle tissue. Ground-up cattle remains were once commonly added to cattle feed as protein, but the government essentially halted the practice nine years ago. Virginia physics teacher raps his lessons For physics teacher Daron Moore, 'Moore rapping' means 'more learning' PORTSMOUTH, Va. (AP) - Daron Moore is a physics teacher and science department head at I.C. Norcom High School. Wearing a white shirt accented with a neatly knotted dark tie and a pen in his pocket, he looks scholarly. Students are often caught off-guard when he breaks out into what he calls "the physics rap." "Physics phun, ICN class No. 1, com- ing at you fast like a bullet from a gun. But don't run, cuz you gotta stand and face the challenge. Understand how Newton's laws keep the whole world in balance." Moore, who goes by the enter- tainment name "The Tcha," recently released a gospel rap album, not-so- coincidently called "The Formula." The equation he's talking about isn't one you'd find in a textbook. On his CD cover, Moore says the formula is U+JL (infinity); or you plus Jesus equals infi- nite life. He's a missionary, who happens to teach physics. Moore produced 1,000 copies of the album and distributed about 700 copies. He gave some away and oth- ers he sold - under his own Portsmouth label, Reformation Records. CDs sell for $999 at DJ's Music & Video in Norfolk and Portsmouth. Rhyming comes in handy during class and in the community. Beyond telling students that physics is cool, he said, his music shows a wider audience alternatives to the violence and sexism and a lack of creativity that he said plays out on television, the radio and in their neighborhoods every day. Sitting in his classroom laboratory with displays of science projects hang- ing on the walls, he said that to reach out to youth "you have to have what is called the wow factor." Moore jogs over to a corner filled with balls, yardsticks and other props. He grabs an old pogo stick and bounces up and down. Then, a bit out of control, he smacks a couple of desks and bangs against a cabinet. Breathing harder but still bouncing, he asks what law of physics this demon- strates. Hearing the answer, Newton's Third Law - every action has an equal and opposite reaction - Moore smiles. Another day, he didn't hesitate to jump on top of a desk and drop orange- sized balls from the ceiling to demon- strate the forces of weight and gravity. Then, he handed students 20 sticks of fettuccine and a meter of tape and offered extra credit to the team who builds a bridge that can withstand the most weight. "Please, do not eat your building mate- rials," Moore said, smirking to his class. "He's goofy," said Chanelle Benton, a 16-year-old junior, and one of Moore's students. He's always cracking jokes, telling stories and rhyming. When he first did "the physics rap" in class, Chanelle admitted, "I thought he was kind of corny - you know, a teacher rapping?" But then she thought about it. "With 4 AP PHOTO Norcom High School physics teacher Daron Moore stands on a table as he outlines an assignment in his "honors physics" class April 5. everything he talks about, he gives us a demonstration," she said. "I see how things are, instead of somebody just tell- ing me." On Friday nights, he steps out of sci- ence mode and serves youth a dose of gospel rap at the Sanctuary of Hope Urban Outreach Center's hip-hop night, called Da Jump Off. About 30 youth are in a group that meets every week at the church in the city's Westhaven neighborhood, near the Midtown area. Moore's expertise and support is wel- come, said Adrian Worth, the director of teen services at the center. "It's very powerful. He's got a mes- sage that changes lives," Worth said. "He has the respect of the teenagers. He has their attention." He raps to them about turning their lives over to Jesus - not drinking or doing drugs. He tells them to turn away from music that exploits women and encourages men to participate in activi- ties that could land them in prison. Moore, 30, said young people aren't the only ones who have learned from his music. As he developed his musical talent, he grew stronger as a Christian. Climate change Air temperatures have warmed over Arctic since 1950s WASHINGTON (AP) - It's becom- ing harder to find the right snow to build an igloo, and melting permafrost is turning land into mud. With cli- mate change the nature of the Arctic is changing, too, in ways that worry the people who live there. The Smithsonian's National Muse- um of Natural History opens a pair of exhibits on Saturday: "Arctic: A Friend Acting Strangely," and "Atmo- sphere: Change is in the Air," discuss- ing what is happening to the climate and how it affects people living in the planet's northernmost areas.

LOUISVILLE, Ky. (AP) - A Tennessee professor who teaches the biblical version of creation will lead the Center for Theology and Science at the Southern Baptist Theological Seminary. Kurt P. Wise, currently a profes- sor at Bryan College in Dayton, Tenn., is replacing William Demb- ski, a leading proponent of intelli- gent design theory, who left to take a teaching job closer to his Texas home. Wise was also director of Bryan College's Center for Ori- gins Research, which supports the "validity of the biblical account" of creation, according to its web site. Wise, who holds degrees in phi- losophy and paleontology from Har- vard University, advocates a form of creationism that says God created the Earth relatively recently. The intelligent design theory tout- ed by Dembski and others says life is too complicated to have arisen by chance, though it does not explicitly identify the designer as God. Federal courts have ruled that both creationism and intelligent design are religious rather than sci- entific ideas. Most biologists say the scientific evidence overwhelmingly supports the theory of evolution.
