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.

Topological Optics Viewing topology in higher dimensionsIan S. OsborneArtistic depiction of a four-dimensional regular lattice that forms a quasicrystalline pattern with fivefold symmetry when projected in two dimensions. The symmetry and topology of physical systems are closely related to the symmetries governing the topological properties. Quasicrystals are ordered systems but have no translation or rotational symmetries.

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.

Optomechanics Motions of the quantum collectiveIan S. OsborneMicro- and nanomechanical oscillators can now be manipulated in the quantum regime. They can be entangled with other degrees of freedom and used for quantum teleportation and quantum storage. To date, these systems have been limited to single or pairs of oscillators. Chegnizadeh et al. now demonstrate scale-up, preparing a collective macroscopic system composed of several individual mechanical oscillators in the quantum ground state.

Plant Genetics Gluten forensicsMadeleine SealeTheft of grains, such as wheat, can now be detected by DNA analysis. PHOTO: HEYWOOD YU/BLOOMBERG VIA GETTY IMAGESAnalyzing human DNA is now commonplace in criminal investigation. However, forensic analysis of plant genetic information is also valuable, for example, to detect grain theft. Kozub et al. analyzed allelic variants encoding wheat gliadin proteins, a component of gluten.

Plant Symbiosis Signaling for fungal nutritionMadeleine SealeArbuscular mycorrhizal fungi and plant root cells, pictured here in a scanning electron microscopy image, exchange nutrients in a symbiotic relationship. PHOTO: EYE OF SCIENCE/SCIENCE SOURCEOpen in viewerMost vascular plants form symbioses in their roots with arbuscular mycorrhizal (AM) fungi. The fungi provide nutrients such as phosphate in return for lipids provided by the plant.

Plant Science Grafting for successMadeleine SealeGrafting plant roots with the shoots of another plant is common in many agronomic settings. This technique can allow combinations of genotypes with beneficial traits to be combined, for example, by grafting disease-resistant roots with high-yield shoots. However, only certain combinations of species and genotypes are compatible. Thomas et al. examined graft compatibility between four Solanaceae species.
