Cancer cells' DNA repair disrupted to increase radiation sensitivity

ScienceDaily (Dec. 1, 2011) — Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells' sensitivity to radiation treatment and kills them more quickly, according to a study in Cancer Prevention Research.Researchers would to like see their laboratory findings -- published in the journal's Dec. 5 print edition -- lead to safer, more effective combination therapies for hard-to-treat pediatric brain cancers like medulloblastoma and high-grade...

Using radiation to sterilize insect pests may protect California fruits and vegetables

ScienceDaily (Nov. 30, 2011) — A new study published in the Journal of Economic Entomology shows that radiation can be used to effectively sterilize the light brown apple moth (LBAM), an insect pest found in Australia, New Zealand, California, Hawaii, Sweden, and the British Isles. The light brown apple moth, Epiphyas postvittana (Walker), feeds on apples, pears, stonefruits, citrus, grapes, berries and many other plants. A native of Australia, it has been found in California since 2007. The California...
