AbstractCells and microorganisms are motile, yet the stationary nature of conventional microscopes impedes comprehensive, long-term behavioral and biomechanical analysis. The limitations are twofold: a narrow focus permits high-resolution imaging but sacrifices the broader context of organism behavior, while a wider focus compromises microscopic detail.

AbstractHigh-cost DNA extraction procedures pose significant challenges for budget-constrained laboratories. To address this, we introduce OpenCell, an economical, open-source, 3-in-1 laboratory device that combines the functionalities of a bead homogenizer, a microcentrifuge, and a vortex mixer. OpenCell utilizes modular attachments that magnetically connect to a central rotating brushless motor.

Correction to: Nature Communications https://doi.org/10.1038/s41467-023-36376-5, published online 28 February 2023The original version of this Article contained an error in Equation (2) for fluidic pumping, and incorrectly read: \({\eta }_{{{{\rm{ex}}}}}=\frac{\rho {u}^{2}}{2}+\frac{32\mu lu}{{d}^{2}}+\frac{4\gamma }{d}\). The correct form of Equation (2) is: \({\eta }_{{{{\rm{ex}}}}}=\frac{32\mu lu}{{d}^{2}}+\frac{4\gamma }{d}\).

AbstractFood consumption and waste elimination are vital functions for living systems. Although how feeding impacts animal form and function has been studied for more than a century since Darwin, how its obligate partner, excretion, controls and constrains animal behavior, size, and energetics remains largely unexplored. Here we study millimeter-scale sharpshooter insects (Cicadellidae) that feed exclusively on a plant’s xylem sap, a nutrient-deficit source (95% water).
