A magnetic moment

In a solid, a mobile charge carrier such as an electron, can subtly interact with its surrounding lattice environment slightly disrupting its order. This distortion is localized around the charge carrier, and the combination of the charge carrier and this distortion forms a quasiparticle called a polaron. Polarons are thought to play an important part in the description of many materials with exotic properties. In this week’s issue, Christian Gross and his colleagues present the experimental observation of individual magnetic polarons, which were predicted to form in a 2D lattice featuring an antiferromagnetic background. The team imaged polarons and their inner structure using a quantum gas microscope to capture variations in the local magnetic environment. This is reflected in the cover image in which the central ball represents the polaron and the filings show the variable nature of the surrounding magnetic environment.

    Ferroptosis is a form of cell death. The finding that cells that have certain mutations in the Hippo signalling pathway are susceptible to ferroptosis might offer a way to treat a cancer called mesothelioma.

    Simulations suggest that Jupiter’s dilute core might be the result of a collision between the planet and a Uranus-mass planetary embryo. This finding indicates that giant impacts could be common during planet formation.

    High salt levels in the soil harm plant growth and limit crop yields. A salt-binding membrane lipid has been identified as being essential for salt perception and for triggering calcium signals that lead to salt tolerance.

    Chemotherapy can halt cancer by causing cells to enter a non-dividing state called senescence, but sometimes it causes tumour cells to proliferate. It now seems that the dynamics of the protein p21 governs which of these fates occurs.
