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.

On December 8, 2025, Space: Science & Technology was officially indexed in the Web of Science: Science Citation Index Expanded (SCIE). All articles published since 2021 will be progressively included into the SCIE database.

The Bharat Innovates 2026 National Basecamp was inaugurated at the Indian Institute of Technology Gandhinagar (IITGN), marking a significant milestone in India’s efforts to identify, strengthen, and globally position its most promising deep-tech innovations. Held from December 18 to 20, 2025, the three-day event brings together approximately 400 startups and research-led innovations that have been shortlisted through a rigorous national screening process. Organised under the aegis of the Ministry of Education and the Office of the Principal Scientific Adviser (PSA) to the Government of India, and coordinated jointly by the Indian Institute of Technology Bombay (IITB) and IITGN, the event saw attendance from scientific luminaries, founders, business leaders, venture capitalists, investors, and sci-tech enthusiasts. 

Speakers at the inaugural session highlighted the programme’s role in strengthening research commercialisation, industry–academia linkages, and policy-backed innovation ecosystems. The closed-door pitching sessions and open deep tech exhibition showcased Innovations spanning 13 strategic domains, including AI, semiconductors, energy, healthcare, manufacturing, and space technologies. The Basecamp serves as a critical mentoring and evaluation stage ahead of the International Showcase to be held next year in France, where Indian technologies will take their place on the global stage. 

Formaldehyde, a highly toxic chemical, must be converted into value-added products. A recent paper by researchers from Chonnam National University presents an engineered enzyme system that converts the highly toxic formaldehyde into L-glyceraldehyde, a valuable chiral compound, with high selectivity and conversion efficiency in a sustainable, one-pot, water-based process. This technology can help better manage environmental pollutants, supporting greener chemical manufacturing.
