💻 Technology

Toshiba Europe scientists have achieved quantum key distribution (QKD) over 254 km of commercial fiber-optic cable in Germany without using cryogenic cooling or high-end lasers, marking a major step toward practical quantum-secure communication. By employing room-temperature avalanche photodiodes and a centralized laser reference system, the team demonstrated stable long-distance quantum encryption at 110 bits per second. The milestone, published in Nature, paves the way for scalable quantum internet infrastructure resistant to future cyberattacks.

🚘 Transport

California-based Joby Aviation has successfully flown its all-electric S4 tilt-rotor eVTOL with a pilot aboard, marking the first manned transition from vertical to horizontal flight and back using a single rotor system. The S4, with a range of 150 miles and top speed of 200 mph, is undergoing FAA certification and aims to launch commercial operations in Dubai later this year. This milestone strengthens the aircraft’s prospects for both commercial air taxi services and military applications.

American company Amprius Technologies has unveiled a production-ready lithium-ion battery with a silicon anode that achieves 450 Wh/kg—an 80% increase in energy density over conventional designs. The SiCore™ battery overcomes silicon's swelling issue, making it compatible with existing manufacturing systems and ideal for aviation and defense applications, including drones and electric aircraft. Its lightweight, high-capacity design could significantly extend flight times and reduce system costs across aerospace sectors.

🚀 Space

French researchers from Ifremer have developed the Lunar Hatch project to test whether fertilized sea bass eggs can hatch and grow in space, laying the foundation for sustainable fish farming on the Moon. Their goal is to provide astronauts with a nutritious, protein-rich food source during long-term lunar missions using recycled water and lunar ice. Ground tests confirm the eggs can survive launch forces, microgravity, and radiation, with the next step being a trial mission to the ISS.

🦾 Robotics

American company Glacier, backed by Amazon, has raised $16 million to expand its AI-powered robotic arms that identify and sort over 30 types of recyclable materials. These robots improve recycling efficiency, reduce contamination, and help solve severe labor shortages at Materials Recovery Facilities (MRFs). Already deployed in several major US cities, the technology also provides real-time waste stream data, enabling smarter recycling decisions.

🌎 Sustainability

Researchers from Florida Atlantic University and collaborators have infused red oak with nanoscale iron minerals to strengthen wood at the cellular level without significantly increasing weight. The resulting material could replace steel and concrete in structural applications like buildings and bridges, offering a sustainable and lower-carbon alternative. The technique, detailed in ACS Applied Materials and Interfaces, uses a cost-effective, eco-friendly process to boost durability while preserving wood’s natural flexibility.
