Novel study maps changes in US immigration policy landscape since 9/11

A Sumatran orangutan has been filmed for the first time crossing a man-made canopy bridge constructed to help the endangered animals bypass a tarred road on the Indonesian island, an NGO said Sunday.

Researchers from Koç University and international collaborators have developed a new algorithm that enables faster and more equitable distribution of disaster relief supplies. By integrating fairness directly into logistics planning, the model reduces inequality in unmet demand by up to 34% without compromising delivery speed. The approach offers a practical tool for improving decision-making in real-world emergency response operations.

Biodegradable plastics hold potential for reducing marine plastic pollution, but degrade too quickly, limiting their practical use. Researchers from Gunma University now show that crab shell by-products can reduce the breakdown rate of biodegradable plastics in seawater by altering the microbial communities that colonize their surfaces, known as the plastisphere. These findings could help design plastics that stay durable during use and then degrade at an appropriate time once in the ocean.
