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.

Maaaring gawing sustansya sa pananim ang ihi ng tao

PHYS

Ipinakita ng mga mananaliksik sa UK na puwedeng gawing low-energy source ng nutrients para sa pananim ang ihi ng tao sa halip na itapon. Gamit ang forward osmosis, nakagawa sila ng fertilizer-rich stream habang mahusay na inaalis ang tubig. Makababawas ito sa wastewater load at synthetic fertilizers.

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.

Researchers created an AR app that acts as a job coach for individuals with intellectual and developmental disabilities, providing real-time guidance for complex tasks. Participants showed immediate, significant improvement, with all completing at least 90% of task steps correctly and independently.
