Washington, Feb 18 : Scientists undertook a study on a 5-day space mission on the shuttle Columbia, which showed sweet potato can regenerate its roots in microgravity.

The study was undertaken by Desmond G. Mortley and colleagues from the Center for Food and Environmental Systems for Human Exploration of Space, G. W. Carver Agricultural Experiment Station, and the Kennedy Space Center.

Seeds of several crops have been grown in microgravity, but this was the first test for plants grown from cuttings.

Cuttings grow roots faster than do seeds, and sweetpotato cuttings regenerate very easily.

Washington, Feb 18 : NASA's Lunar Crater Observation and Sensing Satellite (LCROSS), which will seek water ice on Moon, is enroute from Northrop Grumman's facility in Redondo Beach, California, to the agency's Kennedy Space Center in Florida in preparation for a spring launch.

LCROSS is a low-cost, accelerated-development, companion mission to NASA's Lunar Reconnaissance Orbiter, or LRO.

Washington, Feb 18 : Cancer survivors are more likely to fail in obtaining or retaining a job as compared to healthy individuals, according to an analysis of previous studies.

The trend is more common in survivors of breast and gastrointestinal cancers, adds the review report.

The researchers behind the analysis say that long-term medical and psychological effects of cancer or its treatment may cause impairments that effect social functioning, including the obtainment or retention of employment.

Almost half of all cancer survivors are younger than 65 years.
