Metabolism Artificial sweetener link to vascular diseaseL. Bryan RayAspartame is a widely consumed artificial sweetener. Unfortunately, such sweeteners are linked to an increased risk of cardiovascular disease. Wu et al. explored how aspartame affected atherosclerosis in a mouse model lacking ApoE, a protein that functions in lipid metabolism. Consumption of aspartame made atherosclerotic symptoms worse.

Neuroscience Multisensory memoriesPeter SternIn everyday life, we easily form speech memories during casual conversations. Remembering what someone said and how they said it requires the brain to form an integrated multisensory representation of speech. Theta oscillations in the neocortex and the hippocampus are important for episodic memory formation. Biau et al.

Water Storage Poles on the moveJesse SmithThe Kariba dam on the Zambezi River has created the world’s largest artificial lake. PHOTO: IMPALA PHOTO/ISTOCK PHOTOHuman activities have been conducted at such immense scales that they literally have affected how the world turns. Valencic et al. discuss one dimension of that impact: movement of the poles due to water impoundment.

Neuroscience You see what you expectPeter SternFeedback from higher-level visual processing centers in the brain influences the early stages of object recognition. PHOTO: EYEEM MOBILE GMBH/ISTOCK PHOTOVisual recognition is thought to start with basic object features in the primary visual cortex, reaching the level of object representation at higher cortical areas after processing. However, there is increasing evidence for top-down influences in these pathways. Altavini et al.

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.
