A miniaturized radar chip, developed by researchers at Science Tokyo, advances Integrated Sensing and Communication for Beyond 5G and 6G systems. Measuring just 0.24 mm² and consuming only 9.8 mW, the compact, low-power device generates high-speed, highly linear chirps by embedding linearization directly into the hardware, overcoming traditional speed-versus-accuracy limits and enabling precise sensing for edge and Internet-of-Things devices.

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.

Despite their widespread use in various applications, synthetic polymers such as polyethylene (PE) remain susceptible to structural deformation when exposed to stress. In a new study, scientists from Japan have utilized focused electron beam (FEB) irradiation to precisely induce micro-voids and nano-scale fibrils to improve the mechanical strength of PE. Following irradiation with FEB, PE demonstrated minimal crack opening and prevented further crack propagation. This study can fuel the development of superior polymer-based materials.

Birds currently inhabiting many territories across Africa, Latin America and Asia are, on average, considerably smaller than those that predominated in 1940. This is the conclusion of an international study led by the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB), which documents—drawing on the collective ecological memory of ten Indigenous Peoples and local communities—a reduction of up to 72% in the mean body mass of the bird species present in their territories between 1940 and 2020.
