1. Piston proton pump » The X-ray structure of a membrane complex involved in aerobic respiration (and implicated in neurodegeneration) reveals an unusual piston-like mechanism for pumping protons across the mitochondrial membrane, and provides clues for developing drugs against Parkinson’s and other related diseases.

2. A gene for autoimmunity » Defective sialic acid acetylesterase (SIAE)—an enzyme involved in the regulation of B lymphocyte signaling—infers a greater risk of autoimmune disorders, such as rheumatoid arthritis and type I diabetes, and may contribute to the pathogenesis of such diseases.

3. Super E. coli » The mother cell of E. coli maintains a constant growth rate throughout its replicative life (hundreds of cell divisions), despite accumulating damage and an increased probability of death, suggesting that growth and aging are decoupled, unlike all other studied aging models.

4. Brain blood busters » A newly uncovered mechanism for clearing common brain blood clots provides a potential therapeutic target for stroke recovery and age-related cognitive disorders.

C.K. Lam et al., Nature, 2010 May 27, 465(7297):478–82. Eval by Jaime García-Añoveros, Northwestern Univ; Ray Rodgers, Univ Adelaide ID: 3369956

5. 1st cell with synthetic genome » The creation of the first cell controlled by a synthetic genome marks a long-sought landmark in synthetic biology that could someday be used to engineer microbes for environmental or medical applications.

6. Elite controllers’ killer Ts » HLA B57, a gene commonly found in people who are naturally immune to HIV, causes the body to produce more potent killer T cells that help kill the quickly mutating virus, providing new clues for vaccine research.

A. Kosmrlj et al., Nature, 2010 May 20, 465(7296):350–54. Eval by Torben Lund, University College London ID: 3486956

7. Internal tree clocks » Circadian clock genes control many seasonal traits in deciduous trees, including cold hardiness and bud dormancy, suggesting these widespread genetic clocks play a broad role in plant survival.

Off the cuff remarks\n\n#5. It definitely was NOT a "creation of the first cell controlled by a synthetic genome". It was an impressive manipulation and implantation of a genome in an existing cell. \n\n#7. "Circadian clock genes" ? A miscomprehended terminology.\n\nA circadian rhythm is a roughly 24-hour cycle in the biochemical, physiological or behavioural processes of living entities. It dates back to genes' pre-metabolism period, when life activity was fueled ONLY by direct sunlight. It is an innate feature of Earthlife's primal organisms, the genes. \n\nDov Henis\n(Comments From The 22nd Century)\n03.2010 Updated Life Manifest \nhttp://www.the-scientist.com/community/posts/list/54.page#5065
