がん: 治療での微妙な違い
Cancer: The nuances of therapy p290
Oncologists use drugs that limit a tumour's blood supply to prevent its growth. Although the initial effects of these drugs are beneficial to patients, new data suggest that their long-term effects warrant further study.

地球物理学: 地球地殻の深部にある断熱覆い
Geophysics: Hot blanket in Earth's deep crust p292
Studies of rocks from Earth's crust suggest that the lower crust is a good thermal insulator. The knock-on effects of this finding are many — one being the crust's increased potential to generate more magma.
