Mustafa Aksoy, an associate professor in the University at Albany’s College of Nanotechnology, Science, and Engineering, is part of a large research team that was awarded a two-year, $1.1 million grant to develop radio frequency interference detection and mitigation strategies for future U.S. weather and climate satellites.

Held on 8 May 2025, the 10th UN Multi-stakeholder Forum on Science, Technology and Innovation for the Sustainable Development Goals side event, titled “One Health for All: Synergistic Solutions Advancing SDG3 through Sustainable Science & Inclusive Innovation”, convened global experts to explore integrated strategies for advancing human, animal, and environmental health within the 2030 Agenda. The event highlighted innovations like artificial intelligence (AI)-driven surveillance and low-carbon diagnostics, emphasizing equity and Sustainable Development Goals (SDGs) acceleration. One milestone was the launch of an expert consensus promoting the global One Health index (GOHI), a roadmap to align research and experimental development (R&D) with SDG3 targets. Discussions centered on three key issues covering: the One Health approach for SDGs, the role of GOHI as a scientific tool addressing data fragmentation and capacity disparities, and GOHI's potential to enhance cross-sectoral governance, exemplified by case studies from Japan, Cambodia, and Singapore. A consensus emerged to promote GOHI at the sub-national level, recognizing its value as a comprehensive, structured framework offering practical tools, data transformation capabilities, economic analysis, and global knowledge sharing, despite implementation challenges. Six actionable recommendations were proposed, focusing on strengthening institutional coordination, bridging data gaps, integrating GOHI into governance, piloting localized interventions, mobilizing funding, and building capacity through global partnerships. The event marked a significant step forward, positioning the One Health framework, facilitated by tools like GOHI, as essential for achieving the SDGs and ensuring a healthier, more sustainable future for all.

There’s always a touch of melancholy when a chapter that has absorbed years of work comes to an end. In the case of the Atacama Cosmology Telescope (ACT), those years amount to nearly twenty — and now the telescope has completed its mission. Yet some endings are also important beginnings, opening new paths for the entire scientific community.

The three papers just published in the Journal of Cosmology and Astroparticle Physics (JCAP) by the ACT Collaboration describe and contextualize in detail the sixth and final major ACT data release — perhaps the most important one — marking significant advances in our understanding of the Universe’s evolution and its current state.

ACT’s data clarify several key points: the measurement of the Hubble constant (the number that indicates the current rate of cosmic expansion — the Universe’s “speedometer”) obtained from observations at very large cosmological distances is confirmed, and it remains markedly different from the value derived from the nearby Universe. This is both a problem and a remarkable discovery: it confirms the so-called “Hubble tension,” which challenges the model we use to describe the cosmos.

ACT’s observations also rule out many of the so-called extended models — theoretical alternatives to the standard cosmological model. That’s another “problem,” since it narrows the range of possibilities, but it also represents a new, cleaner starting point: time to stop pursuing these models and look elsewhere.

Last but not least, ACT provides new polarization maps of the cosmic microwave background — the Universe’s “fossil light” — which complement Planck’s temperature maps, but with much higher resolution. “When we compare them, it’s a bit like cleaning your glasses,” says Erminia Calabrese, cosmologist at Cardiff University, ACT collaboration member and coordinator of one of the three papers.

As the number of wireless applications and devices grows, higher standards for the quality of service and navigation performance of mobile networks are required. Numerous critical applications, including unmanned aerial vehicles, internet of things, digital twin, and military systems, require reliable communication and accurate navigation services. To meet these requirements, the development of the sixth generation (6G) network is necessary. 6G networks provide seamless 3-dimensional coverage in space–air–ground–sea area, as well as deep coupling of communication, sensing, and computation. 6G networks will be combined with low Earth orbit (LEO) satellites to construct a universal and intelligent integrated system of communication, sensing, and computing by utilizing the benefits of LEO satellites, such as miniaturization, modularity, large bandwidth, low latency, and wide area coverage. One of the critical construction tasks in this system is the integration of communication and navigation (ICAN), which can break the limitations of the global navigation satellite system, provide high-precision, robust navigation capability, and enable high- quality communication services.
