Human genome count disputed

How many genes does it take to make a person? Well, maybe not many more than it takes to make a small plant. That's the rather humbling indication, anyway, from some recent estimates for one of the most basic numbers in biology. For years, the usual guess has been that there are around 60,000 to 100,000 genes in the human "genome," the collection of DNA that every person carries. That compares pretty impressively to the 25,500 genes in the small flowering plant called Arabidopsis thaliana or thale cress.

Research identifies gene structure of rice

ST. LOUIS -- Scientists have sketched a ``working draft'' of the rice genome -- a step that could speed up improvement of one of the world's most important foods.\r

Health plans control consumer access to the latest medical technology

NEW YORK -- Like the 3 million Americans who regularly take blood thinners, Irene Beaudry must get her blood tested regularly to make sure the pills are not putting her at risk for stroke or internal bleeding. Once a month, the 49-year-old Baltimore sales representative leaves work early and drives to a laboratory for a blood test. She then waits several days to get the results from her doctor.

Astronomers spot object that might be brightest known

NEW YORK -- Astronomers have spotted what appears to be the brightest known object in the universe, a distant quasar that looks like an ordinary star through a small telescope. The quasar, in the constellation Lynx near the Big Dipper, is about 11 billion light-years away. It gives off visible light and infrared emissions, and its brightness in terms of total energy output beats the current record by about tenfold.

Study: Genes' contribution to obesity

PHILADELPHIA -- Don't reach for the anti-fat-gene drug just yet. Scientists have discovered that mapping the biochemical pathways involved in putting on excess pounds is not just a matter of finding a culprit gene and fixing it.

Freshman survey: Political interest hits new

WASHINGTON (AP) -- Three decades after an unpopular war, the civil rights struggle and free speech disputes brought turmoil to college campuses, a record low number of college freshmen show much interest in politics, according to a survey released Sunday. It's even hard to get students riled up about tuition, says one campus Republican.

Leaping over evolution

NEW YORK (AP) - A recent study shows that evolution, commonly thought of as operating over eons, can happen over just a few years. That's nothing new to biologists, who have witnessed remarkably rapid evolution in bacteria, snails, moths and a host of other creatures since Charles Darwin first documented the process in finches. But nobody had ever demonstrated rapid evolution in an actual experiment before researchers took lizards from the Bahamian island of Staniel Cay and introduced them to 14 even-smaller islands nearby.

Scientists question existence of extraterrestrial life

SEATTLE - Is there now - or was there ever - life on Mars? For three days, astronomers, biologists, chemists and geologists debated the Mars question - one of the most momentous in the history of science - at a meeting of the American Association for the Advancement of Science. Scientists who six months ago reported potential evidence for ancient microbes in a Martian meteorite admitted in Seattle this week that they still don't have a definite answer. But they said it's a mistake to declare Mars dead.
