Solution processable perovskites are revolutionising the research field of direct X-ray detectors. Here, the authors discuss the opportunities, challenges, and research strategies for perovskite planar X-ray detectors.

DNA catalysts, known as DNAzymes, have arguably been limited for decades by the lack of mechanistic information. The solution structure of the 8–17 DNAzyme reported by Wieruszekska, Pwlowicz et al. reassesses the current thinking regarding the relationship between structure, dynamic, and metal ion coordination.

Surface observations suggest that carbon may exist in Mercury’s interior. Under planetary mantle pressures and temperatures, carbon may be present as a stable diamond layer which may have important implications for the physical and chemical properties of Mercury.

Atmospheric entry of asteroids or comets can cause significant damage to Earth. Two international bodies, the International Asteroid Warning Network (IAWN), and the Space Mission Planning Advisory Group (SMPAG) are working on dealing with potential threats.

Global climate policy has increasingly acknowledged the specific contributions of Indigenous Peoples. The outcome of COP 28, however, demonstrates that this acknowledgement has not shifted the conceptual foundations of dominant climate solutions, nor has it created space for Indigenous Peoples to effectively contribute. Drawing on our expertise as Indigenous scholars and practitioners, we offer four recommendations to shift climate policy and research away from these foundations towards reciprocal relationships with the natural world – strengthening it for future generations.

The curse of rarity—the rarity of safety-critical events in high-dimensional variable spaces—presents significant challenges in ensuring the safety of autonomous vehicles using deep learning. Looking at it from distinct perspectives, the authors identify three potential approaches for addressing the issue.

Vaccines and clean water shortages continue to give rise to cholera outbreaks in Africa. Coordinated efforts to increase vaccine distribution and improve physical infrastructure are needed while considering future outbreaks and water demands due to conflicts and climate events.

Patient derived tumor xenografts (PDXs) are important models for pre-clinical testing in cancer research and personalized medicine. PDXs often represent patient tumors with high similarity in terms of histology and driver mutations. However, certain limitations exist that warrant a detailed understanding of PDX heterogeneity and evolution. Hynds et al. demonstrate the relevance of primary tumor heterogeneity in PDX model establishment and explore multi-region sampling to determine the extent to which PDXs represent primary tumors.

Recent seismological studies challenge the traditional view that the interface between the core and mantle is a straightforward discontinuity. As seismology is pushed to its observational limits, a complex - potentially compositionally layered - region between the core and mantle is emerging.

Shigella, an important human pathogen, can secrete effector proteins to invade host cells and evade mechanisms of cell-autonomous immunity. In a new manuscript published in Nature Communications, Xian et al. report that the Shigella kinase effector OspG promotes the ubiquitination of septin cytoskeletal proteins to evade cage entrapment.

Aqueous zinc batteries are currently being explored as potential alternatives to non-aqueous lithium-ion batteries. In this comment, the authors highlight zinc’s global supply chain resilience and lower material costs yet caution about its higher mass requirement for comparable charge storage.

Nature Communications has been striving to support Early Career Researchers (ECRs) through different pilot schemes including the peer review mentoring programs and co-review mentoring initiative. The 2^nd Rising Stars workshop, held at the Henry Royce Institute on the 9^th of February, 2024, aims to celebrate and support rising stars within underrepresented groups in Science, Technology, Engineering and Mathematics (STEM) subjects and this greatly aligns with the aspirations in our journal. In this conversation, the experiences and advice shared by representatives from various disciplines in the workshop are translated to a wider audience in Nature Communications. Dr Alex Ramadan (Lecturer at the University of Sheffield), Dr Lucy Whalley (Assistant Professor at Northumbria University), Dr Maddison Coke (Senior Experimental Officer at the University of Manchester), and Dr Yi Liu (Lecturer at Loughborough University) discuss the opportunities and challenges they face towards their career with work-life balance, family and caring responsibility, and diversity and inclusion in their workplace, and share their experiences on how mentorship supports their personal and professional growth.

Roll-to-Roll (R2R) coating is a technology that potentially enhances throughput, reduces costs, and accommodates flexible substrates for fabricating various types of solar cells and modules. Here, authors discuss the R2R revolution to tackle the industrial leap for perovskite photovoltaic devices.

Developmental stress can detrimentally affect adult female reproductive behavior, influencing sexual receptivity and fertility. Recent work has demonstrated neuronal nitric oxide (NO) synthase (nNOS)-promoted NO release in the ventromedial hypothalamus as a nexus between pre-pubertal stress and adult sexual behavior in mice.

Cellular and organismal aging have been consistently associated with mitochondrial dysfunction and inflammation. Accumulating evidence indicates that aging-related inflammatory responses are mechanistically linked to compromised mitochondrial integrity coupled with mtDNA-driven CGAS activation, a process that is tonically inhibited by mitophagy.

Dinoflagellates are ecologically important and essential to corals and other cnidarians as phytosymbionts, but their photosystems had been underexplored. Recently, photosystem I (PSI) of dinoflagellate Symbiodinium sp. was structurally characterized using cryo-Electron Microscopy (cryo-EM). These analyses revealed a distinct organization of the PSI supercomplex, including two previously unidentified subunits, PsaT and PsaU, and shed light on interactions between light harvesting antenna proteins and the PSI core. These results have implications with respect to the evolution of dinoflagellates and their association with cnidarians.

Arboviral infections are major public health threats, with 100 million people estimated to get sick annually from dengue infection alone. Globally, the risk of arboviruses is likely to further increase both within, and outside of, affected regions due to a combination of factors including climate change, human mobility, and other societal factors. Despite the availability of vaccines for some arbovirus infections, there is a lack of specific antiviral treatment options. Professor Johan Neyts at the University of Leuven, Belgium, has been working on developing antiviral strategies for more than 30 years. His current research focuses on developing antiviral drugs and vaccines against emerging and neglected viruses many of which are arboviruses. In this Q&A, he discusses the risks associated with vector-borne virus infections, challenges in developing efficient drugs for treatment, and current promising efforts to address these challenges.

Multidisciplinary culture-dependent and -independent techniques elucidate the unique microbial nitrogen cycle in nutrient-poor coastal Antarctica soils and reveal the contribution of novel key microbes to their nitrogen budget.

Can many-body systems be beneficial to designing quantum technologies? We address this question by examining quantum engines, where recent studies indicate potential benefits through the harnessing of many-body effects, such as divergences close to phase transitions. However, open questions remain regarding their real-world applications.
