Measurements of physiological and geometrical parameters of the sieve tube system in Ipomoea nil provide strong support for pressure driven mass flow.

An important rice reovirus hijacks exosomes to traverse the apical plasmalemma into saliva-stored cavities in the salivary glands of insect vectors, facilitating viral horizontal transmission into rice phloem.

Immune markers measured at the early stage of COVID-19 infection are associated with various clinical outcomes and can be used to predict disease progression, T cell memory, viral shedding, and the antibody response of the COVID-19 patients.

A study of solute and macromolecule trafficking in plants reveals a previously undescribed route for carbon distribution in growing root tissues.

3D reconstruction for an insect provides new internal structures at nanometer resolution, and the reconstructed feeding insect reveals unexpected contraction of stylet protractors and suggested a novel phloem sap-sucking model.

Simultaneous 2-photon imaging of striosomes and matrix in mice shows that striosomes preferentially encode reward-predicting cues whereas both striatal compartments demonstrate reward-related activity.

A longitudinal study of open access levels at 1,207 research institutions worldwide reveals high performing institutions in Latin America, Africa and Asia.

Genetically-encoded platforms direct kinase inhibitor drugs to organelles to reveal new dimensions of local kinase signaling.

Building on previous work (Pigott et al. 2014), estimates of areas of potential transmission of Ebola virus are revised and updated to provide a contemporary map for use by researchers and policymakers.
