Researchers in the UK have shown that human urine could become a low-energy source of crop nutrients instead of being flushed away. Using forward osmosis, they concentrated urine into a fertilizer-rich stream while removing water efficiently. The approach could cut wastewater strain, save energy and reduce reliance on synthetic fertilizers.

Urin als Quelle für natürlichen Dünger

PHYS

Menschlicher Urin kann mithilfe einfacher Vorwärtsosmose zu einem düngerreichen Strom konzentriert und so als nachhaltige Nährstoffquelle für Pflanzen genutzt werden. Das Verfahren kann helfen, Kläranlagen zu entlasten, Energie zu sparen und Chemikalien zu ersetzen.

Researchers have created a nanoelectronic device that uses switching currents about a million times lower than conventional designs, reducing energy use in AI hardware by up to 70%. Inspired by the human brain, it performs reliably across thousands of cycles and can store data for about a day, pointing to more efficient computing.

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.
