A sixth-grader from Ann Arbor, Michigan, has developed a low-cost firefighting drone designed to help tackle one of the most dangerous challenges faced by firefighters: reaching and suppressing fires without putting people directly in harm’s way. Sanat Pandit, a student at Greenhills School, built a $300 unmanned aerial vehicle that uses thermal imaging, sonar and path-planning technology to locate and target hot spots.

A team at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) has spent eight weeks 3D-printing a massive steel mold that stands 6 feet tall, measures 4 feet wide and weighs nearly 2 tons. The tool, developed with Boeing, is designed for manufacturing thermoplastic composite aircraft components and will contribute to NASA’s Hi-Rate Composite Aircraft Manufacturing (HiCAM) project.

India has proven its capability to design and launch complex spacecraft independently.The nation now focuses on building industrial depth for space sovereignty and self-reliance.A burgeoning private sector and numerous startups are transforming India's space ecosystem.Future missions aim for a space station and lunar exploration by 2040.Component-level self-reliance remains a critical challenge for sustained space endeavors.

Physicists at CERN's Large Hadron Collider have found strong evidence for quantum entanglement.Two short-lived Z bosons, produced from a Higgs boson decay, showed quantum correlations.This observation confirms quantum mechanics' strange predictions in extreme energy environments.Researchers reconstructed Z boson properties from their decay products for analysis.Future experiments will further investigate quantum phenomena at even higher energies.

Bonaire's dry forests show recovery after 15 years of reduced herbivore pressure.Fenced plots and widespread goat removal revealed more young trees establishing.Natural recovery was limited to fewer species, necessitating active planting efforts.Researchers planted thousands of seedlings, which generally survived well across sites.Long-term management and local involvement are crucial for sustained forest restoration.
