Researchers at the University of Waterloo and University Health Network have developed MetaboSense, a new device that continuously monitors key indicators of donor lung health during ex vivo lung perfusion, a process used to assess lungs outside the body before transplantation. Unlike current methods that rely on hourly manual testing, MetaboSense provides real-time measurements of glucose and lactate levels, giving clinicians a more detailed picture of lung function and potentially helping them identify more viable donor lungs. The researchers believe the technology could reduce the number of donated lungs that are rejected, helping address organ shortages for patients with end-stage lung disease, while its modular design may also allow it to be adapted for monitoring other organs such as the liver, kidney, heart and pancreas.

A patented sensorized pen for the early screening of writing difficulties. A study by Politecnico di Milano and the University of Insubria (Varese and Como) has been published, involving more than 700 children from across the entire primary and lower secondary school cycle. The participants used the THInkPen (Tele-Health Ink Pen) while completing two BVSCO-3 tasks, the Battery for the Clinical Assessment of Writing and Orthographic Skills. This is the most widely used test in Italy for assessing writing difficulties, dysgraphia and dysorthography.

Researchers have demonstrated a direct bridge between vortex electrons and structured electromagnetic radiation. By sending an annular electron beam through an all-metal slow-wave structure, they transferred the electron beam's helical topology into measurable orbital angular momentum and a polarization-skyrmion texture. Multiple optical diagnostics confirmed the mapping, while repeated single-shot measurements showed reproducibility. The proof-of-principle platform could support structured-radiation sources and noninvasive diagnosis of vortex-electron states across future spectral bands and frequencies.

Electric fields can reliably reverse magnetization in nanoscale structures of the multiferroic material BiFe_0.9Co_0.1O₃ (BFCO), as reported by researchers from Science Tokyo. Multiferroic materials display coupled electric and magnetic order, making them attractive for low-power memory devices. The team fabricated 190 nm BFCO nanodots and used advanced imaging techniques to directly observe the restructured electric polarization arrangement upon applying an electric field, driving a persistent reversal of magnetization.

Accurately predicting passenger flows is essential for preventing congestion and delays in subway networks. In a recent study, researchers developed a multi-time-scale model that uses recurring day-to-day and week-to-week travel patterns to predict both passenger destinations and travel times one day ahead. Tested on Shenzhen subway data, the model outperformed several widely used forecasting methods across most stations.
