Experts: Careless work of Texas medical examiners costly

Over the years, Texas medical examiners have misidentified bodies, botched examinations and had to do a double take on cases of individuals later exonerated by law enforcement. That has opened the door for innocent men and women to go to prison and killers to go free. The slapdash work of some medical examiners could also allow public health threats, wrongful deaths and preventable medical errors to go undetected, experts warn. | 09/27/09 20:14:38 By - Yamil Berrad

Beating, dripping pig heart: It's gross, but it saves lives

The sight of a dripping-fresh, human-sized heart, it turns out, is both repulsive and attractive. Especially when it's suspended in the open among an elaborate array of tubes, pumps and valves. And when it's pulsing as though alive. | 05/28/09 15:11:00 By - Jay Price

Kansas girl names 'Curiosity,' NASA's new Mars rover

The good news on damaged ecosystems: Some recover fast

That's the conclusion of a study published Wednesday by two ecologists who studied such disasters as the Exxon Valdez oil spill and deforestation in the Amazon River basin. The upbeat findings should spur more restoration efforts, the study's authors conclude. | 05/27/09 15:52:00 By - Frank Greve

Some GPS satellites could fail before replacements arrive

GPS satellites originally scheduled to head skyward in 2006 in a $7 billion-plus program aimed at keeping the system going are awaiting launch in 2010. The delay means pieces of the high-altitude network could start falling out of service as early as next year. Such decay in the system could ultimately foul everything from the accuracy of U.S. bombs to the reliability of your neighborhood cash machine. | 05/27/09 07:18:22 By - Scott Canon

Finally, space station gets to fulfill its science mission

On Wednesday, three astronauts — a Russian, a Canadian and a Belgian — are to ride a Russian Soyuz spacecraft from Kazakhstan up to the nearly completed space station, the first long-term human habitat in space.

Miami park plan would keep ancient Indian artifact hidden

The Miami Circle is a 2,000-year-old Native American site that taxpayers shelled out $27 million to buy 10 years ago. Now a frugal plan would create a low-key park around the ancient landmark. But the circle itself would remain hidden because no one has a plan or the money to display it. | 05/26/09 15:59:25 By - Andres Viglucci

Zombie fire ants wander in Texas — until heads fall off

It sounds like something out of science fiction: zombie fire ants. But it's all too real. Fire ants wander aimlessly away from the mound. Eventually their heads fall off, and they die. The strange part is that researchers at the University of Texas at Austin and Texas A&Mís AgriLife Extension Service say making "zombies" out of fire ants is a good thing. | 05/12/09 07:43:43 By - Bill Hanna

All we do now to save salmon could mean nothing

No matter what actions the world takes to reduce greenhouse gases, river temperatures in more than half of the lower-elevation watersheds may exceed 70 degrees by 2040 - too hot for salmon. | 05/03/09 10:17:55 By - Rocky Barker

Inspectors find safety problems at nuclear weapons complex

Contractors at one of the nation's major nuclear weapons complexes repeatedly used substandard construction materials and components that, could've caused a major radioactive spill, a recently completed internal government probe has found. One of the materials used at the Savannah River Site on the South Carolina-Georgia border failed to meet federal safety standards and "could have resulted in a spill of up to 15,000 gallons of high-level radioactive waste," the Energy Department's inspector general found. | 05/02/09 23:00:00 By - James Rosen

Researchers can't agree on severity of swine flu outbreak
