Radioactive cesium ions, due to their high-water solubility, pose a serious threat to human health and the environment. Conventional adsorbents such as Prussian blue (PB), although effective for cesium removal, often involve complex fabrication and high operational costs. Researchers have now developed an innovative electrochemical electrode by depositing PB onto chemically treated carbon cloth, achieving high cesium adsorption capacity and excellent reusability, with strong potential for practical wastewater treatment applications.

Researchers at Case Western Reserve University have discovered a way to breach one of cancer’s most stubborn defenses: the impenetrable fortress that solid tumors build around themselves. By injecting nanobubbles filled with inert gas into tumors and “jiggling” them with ultrasound, the team successfully broke down tumor barriers enough for treatment-bearing molecules to get inside, according to results of a new study published in ACS Nano.

MRI scans often struggle to capture clear images of deep or delicate tissues. Researchers at the Max Delbrück Center now report in “Advanced Materials” a new lightweight antenna that boosts image quality and may shorten scan times ­– without changing existing MRI machines.
