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.

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.

After nearly five years of collaborative work, the European Horizon 2020 REST-COAST project convened for its final consortium meeting in Barcelona in early February. On the agenda were the main results that demonstrate how nature-based solutions (NbS), operational tools, business plans and policy insights can support evidence-based decision-making across Europe to reduce coastal risks, restore ecosystems and biodiversity, while improving the well-being of citizens.

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.

Among the enduring challenges of storing energy—for wind or solar farms, or backup storage for the energy grid or data centers—is batteries that can hold large amounts of electricity for a long time. In addition to having a large capacity—potentially enough to power a neighborhood or small city for days or weeks—ideally these batteries would be safe, affordable and environmentally harmless. With an eye toward meeting those benchmarks, researchers at Case Western Reserve University are developing novel electrolytes—fluids that can conduct ions—for rechargeable flow batteries.
