We summarize the week's scientific breakthroughs every Thursday.
- 			 Physics PhysicsSailing toward the island of stabilityThe creation of six new superheavy isotopes has encouraged researchers who hope to find long-lived elements of even greater mass. 
- 			 Physics PhysicsHoly moleyAdding more decimal places to Avogadro constant could produce a better definition of the kilogram.

- 			 Physics PhysicsPhysics Nobel goes to grapheneDiscovered only six years ago, the 2-D carbon sheets have spun off a new field of research. 
- 			 Physics PhysicsGlacier found to be deeply crackedA new study finds deep fissures in Alaska ice that could affect future responses to melting. 
- 			 Physics PhysicsBeing single a real drag for sporesLaunching thousands of gametes at once helps a fungus waft its offspring farther.

- 			 Math MathPotato chips: A symptom of the U.S. R&D problemLast year, U.S. consumers spent $7.1 billion on potato chips — $2 billion more than the federal government’s total 2009 investment on research and development. There’s something wrong, here, when Americans are more willing to empty their wallets for the junk food that will swell their waistlines than for investments in the engine driving the creation of jobs, economic growth and national security.

- 			 Tech TechEverything really is relativeTwo tabletop experiments demonstrate the time-warping principle at the human scale. 
- 			 Tech TechA compass that lights the wayResearchers develop a highly sensitive optical instrument for measuring magnetic fields. 
- 			 Physics PhysicsString theory entangledScientists forge an intriguing mathematical link between black holes and the physics of the very small. 
- 			 Tech TechTar sands ‘fingerprint’ seen in rivers and snowA new study refutes a government claim (one echoed by industry) that the gonzo-scale extraction of tar sands in western Canada — and their processing into crude oil — does not substantially pollute the environment. By Janet Raloff
