PLANTS, PEOPLE, PLANET, EarlyView.As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Small, EarlyView.Four‐dimensional STEM comprises a vast portfolio of electron microscopy methods in one data set, conventional plane‐wave illumination TEM being one of them. Here, the principle of reciprocity is employed to produce true structural projections of misoriented ferroelectric domains at atomic resolution. By reciprocal TEM imaging from four‐dimensional STEM
