American Scene: New AIDS-like disease in Asia not contagious

Story Topics

Researchers have identified a mysterious new disease that has left scores of people in Asia and some in the United States with AIDS-like symptoms even though they are not infected with HIV.

The patients’ immune systems become damaged, leaving them unable to fend off germs as healthy people do. What triggers this isn’t known, but the disease does not seem to be contagious.

This is another kind of acquired immune deficiency that is not inherited and occurs in adults, but doesn’t spread the way AIDS does through a virus, said Dr. Sarah Browne, a scientist at the National Institute of Allergy and Infectious Diseases.

She helped lead the study with researchers in Thailand and Taiwan, where most of the cases have been found since 2004. Their report is in Thursday’s New England Journal of Medicine.

“This is absolutely fascinating. I’ve seen probably at least three patients in the last 10 years or so” who might have had this, said Dr. Dennis Maki, an infectious-disease specialist at the University of Wisconsin in Madison.

Curiosity starts first trip along Martian surface

PASADENA — Curiosity took its first test drive around the gravel-strewn Martian terrain Wednesday, preparation for the ultimate road trip to find out if the Red Planet’s environment could have supported life.

The six-wheel NASA rover did not stray far from the spot where it landed more than two weeks ago. It rolled forward about 15 feet, rotated to a right angle and reversed a short distance, leaving tracks in the ancient soil.

Mission managers were ecstatic that the maiden trek of the $2.5 billion mission was glitch-free.

“It couldn’t be more important,” said project manager Peter Theisinger at the NASA Jet Propulsion Laboratory. “We built a rover. So unless the rover roves, we really haven’t accomplished anything. … It’s a big moment.”

The short spin came a day after Curiosity successfully wiggled its wheels to test its steering capabilities.

Curiosity landed in Gale Crater near the Martian equator Aug. 5 to explore whether the environment once supported microbial life. The touchdown site has been named Bradbury Landing in honor of the author of “The Martian Chronicles,” the late Ray Bradbury, who would have turned 92 on Wednesday.

2 men sentenced to 5 years each in militia plot

GAINESVILLE — Two Georgia men were sentenced Wednesday to five years each in prison for trying to get an unregistered explosive and an illegal gun silencer in what prosecutors describe as a plot to attack government targets.

U.S. District Judge Richard Story sentenced Frederick Thomas, 73, and Dan Roberts, 68, to the maximum sentence allowed under the plea agreement they reached with the government with credit for time served since their arrests.
