The advent of the fifth-generation (5G) technology has revolutionized the way we think about communication networks, enabling a plethora of new use cases and scenarios that were not possible with previous generations of wireless technology. The existing 5G communication networks predominantly rely on terrestrial communication infrastructure, which, however, exhibits several notable limitations such as capacity constraints, latency issues, and energy inefficiencies, necessitating this next-generation leap. The 6G aims to provide a comprehensive solution for a hyperconnected, intelligent, and immersive digital ecosystem, seamlessly integrating terrestrial, airborne, and spaceborne networks which is referred to as the space-air-ground-sea integrated network (SAGSIN). A traditional SAGSIN scenario mainly includes 3 segments: spaceborne network, airborne network, and terrestrial network. The classical SAGSIN architecture has shown remarkable capabilities in providing massive connectivity by integrating spaceborne, airborne, and terrestrial cellular networks, which, however, encounters inherent technical challenges against their respective practical implementation. On the other hand, the philosophy of near-space communications (NS-COM) is gradually emerging. The distinctive location of near space which is 20 ~ 100 km above Earth’s surface positiones at the core of the SAGSIN, thus allowing the NS-COM network to address the shortcomings of traditional spaceborne, terrestrial, and airborne networks. NS-COM present a promising addition to SAGSIN, making them the final piece of the SAGSIN puzzle.

With winter approaching and people spending more time indoors, the quality of the air they breathe becomes increasingly important. Especially during cold and flu season.

Researchers at UBC Okanagan are exploring an air-cleaning device that can remove airborne pathogens, offering a powerful new tool for reducing the spread of respiratory diseases in enclosed spaces.

 Landon Marston, associate professor of civil and environmental engineering at Virginia Tech, is part of a group of researchers that have completed the first comprehensive assessment of the Rio Grande–Bravo basin, using decades of data from 14 sub-basins across the United States and Mexico. This multi-institutional effort, led by Brian Richter at Sustainable Waters, offer the clearest look yet at how limited water supplies are being allocated and where the system is breaking down.

After surpassing the 600-scholarship milestone last year, this year the remarkable generosity of private individuals, companies, and institutions enabled Goethe University to set a new participant record. A total of 280 private individuals, 45 companies, and 52 nonprofit organizations donated a €1,116,000 to Goethe University in 2025, which according to the matching principle was doubled by the Federal Ministry of Research, Technology and Space (BMFTR). This translates into a total of €2,232,000 raised for scholarship recipients.
