Investigadores de China y Hong Kong desarrollaron una batería de base acuosa que utiliza sales de magnesio y calcio — los mismos minerales del suero del tofu — como electrolito. Completa 120.000 ciclos de carga, no contiene materiales inflamables y cumple con los estándares de seguridad para su eliminación y está diseñada para almacenamiento de energía renovable a escala de red eléctrica.

Scientists build a non-toxic water battery that survives 120,000 charge cycles

ZME SCIENCE

Researchers in China and Hong Kong developed a water-based battery using magnesium and calcium salts — the same minerals found in tofu brine — as its electrolyte. Published in Nature Communications, the battery completed 120,000 charge cycles, contains no flammable materials, and passed disposal safety standards. It is designed for grid-scale renewable energy storage.

Two new studies suggest offshore wind farms can expand without putting migratory birds at major risk. Over 18 months, researchers tracked more than four million bird movements using radar and AI cameras and found that more than 99.8% reliably avoided turbine blades, showing clean energy and wildlife protection can work together.

McGill University researchers found that treating peanuts with cold plasma — an ionized gas that alters protein structure — for just 25 minutes reduces allergic immune response by nearly 70%. The method preserves taste and nutrition and could be extended to eggs, hazelnuts, and other common allergens, opening the door to a wider range of safer foods.

New research from Leeds reveals that inclusive secondary schools effectively prevent students from becoming "NEET" (not in education, employment, or training). Prioritizing fewer suspensions and supporting lower-achieving pupils fosters a sense of belonging that encourages every young person to stay engaged and thrive beyond Year 11.
Inclusive Schools Successfully Reduce Student Dropout Rates
Using agrovoltaic systems and reduced irrigation, the approach lowers water use while maintaining efficient yields. Solar panels reduce evaporation by providing shade, and help plants cope with heat, allowing land to produce both food and clean energy at the same time.
