Another look back on this week in science:

• A new study replicates the results of previous research, suggesting that gargling sugar water can temporarily help with self control by activating the motivational parts of the brain.
• Simulations by researchers at Carnegie suggest special crystals that keep their electrical fields can be used as very efficient heat pumps, and could be used in the future to cool microchips.
• Scientists transformed algae into gasoline in just 1 minute. At $20 a gallon, it’s not an economical replacement, but it’s a promising step forward.
• Yet another potentially habitable planet was discovered.
• Flaws in the way science is funded and published threaten the scientific method. This article argues we need a more transparent peer review process with more emphasis on replication, and I agree.
• A black hole is discovered in Orion’s sword.
• Blind mole rats don’t get cancer because the cancerous cells commit suicide.
