Here's Science's Top 10 list of achievements for 2006:
1) A controversial proof of a 102-year-old mathematical puzzler has taken the top spot on the journal Science's annual list of scientific breakthroughs. It was Russian mathematician Grigory Perelman's proof of the Poincare Conjecture, literally one of the field's million-dollar challenges, that most impressed America's premier peer-reviewed science publication.

2) Fossil DNA: Using new techniques for decoding and analyzing DNA, researchers captured genetic information from Neanderthal and mammoth fossils.
3) Shrinking ice: Researchers documented a disturbing trend this year. The Antarctic and Greenland ice sheets are losing ice, at an ever faster rate, to the oceans.
4) Transitional fish: The discovery of a fossil fish with sturdy, jointed fins made a big splash in 2006. The fish is the closest known kin to limbed vertebrates and provides a window into how life left the oceans and ventured onto terra firma.
5) Invisibility cloaks: Though it looks nothing like Harry Potter’s magical cape, the invisibility "cloak" that scientists developed this year is the first rudimentary device for shielding objects from view. The device guides incoming microwaves in such a way that they produce neither a reflection nor a shadow.
6) Hope for aging eyes: Researchers who study the form of vision loss known as age-related macular degeneration showed that the drug ranibimuzab improves vision in some patients and identifying several genes that influence a person’s susceptibility to the disease.
7) Split happens: From beach mice, to fruit flies, to butterflies, a variety of animals helped scientists uncover genetic changes that lead to the evolution of a new species.
8) Microscopic frontier: This year, biologists used new microscopy techniques that enabled them to see details smaller than about 200 nanometers, giving them a clearer view of the fine structure of cells and proteins.
9) How memories are made: Several discoveries in 2006 brought neuroscientists closer to understanding how the brain records new memories. The so-called "long-term potentiation" process that strengthens connections between neurons now seems even more likely to be the basis for remembering.
10) New breed of RNA: Scientists discovered a new class of small RNA molecules that shut down gene expression, called "Piwi-interacting RNAs."
