10. CAGED FURY 籠子裡的狂暴者

俄羅斯科學家通過比較攻擊性的褐家鼠和溫順的褐家鼠,找到幾處和溫順相關的遺傳區域。這一研究有助於我們理解家養動物的馴養過程。

Rats don’t deserve their bad name, but this ball of fury won’t win over many murophobes. Russian scientists bred this aggressive rat strain to compare it with more docile creatures in a study on domestication that has teased out several genetic regions linked to tame traits.  VINCENT J.

11. ULTRA-FLYWEIGHT蒲公英上的超輕量級金屬

Tobias Schaedler小組通過在多聚微型網格上鍍鎳-磷,之後在移去多聚物骨架的方法,創造出最輕的金屬晶格。

Balanced on a dandelion, this ordered metal lattice could usurp other, structurally disordered, ultra-light materials. Tobias Schaedler of HRL Laboratories in Malibu, California, and his team created it by plating nickel–phosphorus onto a polymer microlattice, and then removing the polymer skeleton.  D.
