New research shows that cyberbullying should be classified as an adverse childhood experience due to its strong link to trauma. Even subtle forms—like exclusion from group chats—can trigger PTSD-level distress. Nearly 90% of teens experienced some form of cyberbullying, accounting for 32% of the variation in trauma symptoms. Indirect harassment was most common, with more than half reporting hurtful comments, rumors or deliberate exclusion. What mattered most was the overall amount of cyberbullying: the more often a student was targeted, the more trauma symptoms they showed.

Tianjin Normal University (Prof. Cheng-Peng Li) and Southeast Normal University (Prof. Yan-Qian Lan) have developed crystalline porous framework (CPF) composite beads to trap ⁹⁹TcO₄^– in nuclear wastewater. 1 g of beads processed 4.8 L of pre-treated simulated waste, with residual Tc levels reduced to 0.026 ppb—significantly below the WHO (0.159 ppb) and U.S. EPA (0.053 ppb) drinking water standards (calculated from nonradioactive surrogate ReO₄^–). This scalable strategy enables deep purification of trace radionuclide, enabling industrial deployment of nanoscale adsorbent technologies.
