Science magazine's breakthroughs of 2006

    * 1. The Poincare Conjecture. Reclusive Russian mathematician Grigory Perelman apparently solved the venerable mathematical problem.
    * 2. Digging out fossil DNA. Researchers used new techniques to sequence more than one million bases of nuclear DNA from a Neanderthal.
    * 3. Shrinking Ice. Glaciologists discovered that the world's two great ice sheets were indeed losing water to the oceans - at an accelerating pace.
    * 4. From sea to land. Details emerged of a 375-million-year-old fish that fills an evolutionary gap between sea creatures and land animals.
    * 5. The Ultimate Camouflage. A British-American team built a "metamaterials" cloaking device, that rendered an object invisible to microwaves.
    * 6. Ray of Hope. Clinical trials show the drug ranizumab improved the vision of about one-third of patients with an age-related condition that causes degeneration in vision.
    * 7. The road to speciation. Studies on the fruit fly and on butterflies aided our understanding of how species arise.
    * 8. Beyond the light barrier. New microscopy techniques allowed biologists to get a clearer view of the fine structure of cells and proteins.
    * 9. The Persistence of Memory. Neuroscientists provided insights into how the brain records new memories.
    * 10. Small molecules. Researchers reported a new class of small RNA molecules that shut down gene expression.
