Researchers propose a synergistic computational imaging framework that provides wide-field, subpixel resolution imaging without added optical complexity via a metalens-transformer design. They experimentally validated performance on real thyroid pathology sections with reasonable cross-tissue generalizability, and feature a compact, low-cost configuration suitable for portable diagnostic applications. This study was published in PhotoniX on December 3, 2025.

A new study of 2,000 U.S. adults shows dark web users report much higher rates of depression, paranoia, suicidal thoughts, self-injury and digital self-harm than surface web users. People with suicidal thoughts were nearly three times more likely to use the dark web, while those engaging in self-injury or digital self-harm were up to five and 19 times more likely, respectively. Researchers suggest dark web use may reflect underlying mental health struggles and urge professionals to reach vulnerable users in these hidden spaces.

A new proof-of-concept study from researchers at Bar-Ilan University reveals a surprising finding: incorporating more walking into public transportation commutes can improve health—without adding extra travel time.

The study, part of Prof. Jonathan Rabinowitz’s More Walking Project and conducted in collaboration with the Israeli Smart Transportation Research Center (ISTRC), analyzed potential commuting routes for over 2,100 employees traveling to Bar-Ilan University. By increasing the walking distance thresholds in trip planning, researchers found that most commuters could benefit from an average of nine minutes of walking—without lengthening their total travel time.
