An atlas of plant selenium metabolism

New Phytologist, EarlyView.
Summary Selenium (Se) is not only a rare and toxic element but also an essential micronutrient for humans and animals that is often in short supply. Terrestrial plants do not require Se, but it can have growth‐promoting or negative effects, depending on the exposure level.

Self‐Calibrating Ratiometric DNA Aptamer Probe for Quantitative ATP Imaging in Living Cells

Chemistry – A European Journal, Volume 32, Issue 11, 16 March 2026.
We developed the RFA–ECHO probe, an internally calibrated ATP sensor that remains responsive across millimolar ATP levels. Its self‐correcting Cy5/ECHO ratio ensures accurate quantification independent of probe uptake. Compared with FRET‐based sensors, it yields a robust ratiometric shift, distinguishing high‐ATP cancer cells from normal ones, enabling
