Second Extremely Resistant Bacteria Sequenced Is Surprisingly Different From First
Researchers have completed the whole-genome sequence of Deinococcus geothermalis, which is only the second extremely radiation- and desiccation-resistant bacterium to be sequenced.

Most surprisingly, many of the unique D. radiodurans genes that were strongly implicated in resistance over the last decade have turned out to be unrelated to its survival, and are not present in D. geothermalis.[see more details in sciencedaily.com]

The findings provide a precise and quantitative framework for studying the possible mechanisms that allow cells to monitor and sense their size.[see more details in sciencedaily.com]
Smallpox Evolved Earlier Than Believed, According To Molecular Clock Analysis
Smallpox is older than previously thought. Researchers created a molecular clock by looking at the rate of random mutations in the smallpox-causing virus collected in 47 locations around the world, from 1946 -- 1977. The variation between the strains was compared to sequences from the most similar animal poxes. The results indicated that a mild and more severe strain diverged either 16,000 or 68,000 years before present, depending on whether accounts from East Asia or Africa are used to calibrate the molecular clock. In either case, this divergence stretches further back in time than previously believed.[see more details in sciencedaily.com]

Surprise In The Organic Orchard -- A Healthier Worm In The Apple
Insects can catch more than a cold from certain viruses. Some viruses can be lethal to pest species - turning their insides to soup - without harming beneficial insects or other organisms. Hence they are used as an environmentally friendly means of biological crop protection worldwide. The proverbial worm in the apple, the codling moth caterpillar, has been controlled in European orchards for years. But in southwest Germany, some organic apple growers noticed that the virus was losing its effectiveness. Pest resistance to chemical insecticides is common in agriculture, but resistance to viruses had never been a problem in the past. Scientists have now discovered how the codling moth rapidly developed virus resistance.[see more details in sciencedaily.com]
