Cryosphere Soft deformationJesse SmithCross-polarized light microscopy reveals how ice grain patterns change upon shearing. Future rises in sea level will depend primarily on the rate at which the Antarctic and Greenland ice sheets discharge their ice into the sea, and that rate depends critically on the flow properties of the temperate ice that exists near the beds and within the margins of the fastest-flowing ice streams. Schohn et al.

Deep-Sea Life A bizarre sea slug in the deepDi JiangDeep-sea biodiversity and the ecological adaptations of life are less explored in the bathypelagic zone than in other oceanic zones. Robison and Haddock describe Bathydevius caudactylus, a new nudibranch (sea slug) species that is found at depths of 1013 to 4009 meters in the eastern North Pacific Ocean.

Cognition With intentionSacha VignieriOnce thought to be unique to humans, tool use has now been documented across animals, from mammals to birds and even fish and insects. Thus, it should be no surprise that the elephant, a cognitively advanced mammal, would readily make use of a new tool, as documented by Urban et al. Even more interesting was the disruption of one animal’s use of a hose to shower by another, in an apparent act of intentional disruption.

Energy Economics Decoupling too slowlyJesse SmithEfforts to decouple economic growth from fossil fuel use are falling well short of targets. (Pictured: an old crude oil well pumpjack)PHOTO: ANAN KAEWKHAMMUL/ALAMY STOCK PHOTOModern economic growth has depended on fossil fuel burning, but if we are to avoid the most serious consequences of climate change, then economic growth must be decoupled from hydrocarbon energy generation.

Lizard Genetics Dosage compensation in the anoleCorinne SimontiMale green anoles use a long noncoding RNA to maintain the right amount of gene expression from their single X chromosome.

Wind Turbines Better bladesJake S. YestonWind turbine blades are material intensive and are currently made with resins that are difficult to recycle. PHOTO: PETER MACDIARMID/GETTY IMAGESWind energy is a key component of the general push to power the world more sustainably. However, modern blades for use in wind turbines are assembled with epoxy resins that are resource intensive to manufacture and cannot be easily recycled. Clarke et al.
