▲ Abstract :
Starburst galaxies often host multiphase, galaxy-scale winds thought to enrich the circumgalactic medium and limit further star formation by disrupting interstellar gas clouds. These winds are primarily powered by supernovae, but it remains unclear how supernova energy forms an organized flow. Here we use the Resolve spectrometer on the X-ray Imaging and Spectroscopy Mission to show that the hot (T = 2 × 107K gas in the nucleus of the starburst galaxy M82 is moving quickly, with a line-of-sight velocity dispersion.

This is consistent with a hot, nuclear wind generated by thermal pressure. We show that a free-wind model reproduces the measured temperature but underpredicts the velocity. The inferred mass and energy outflow rates from the nucleus, about 7 M⊙ yr-1 and 4 × 1042 erg s-1, require that most supernova energy is thermalized. These outflow rates provide enough energy to power the 30 M⊙ yr-1cool outflow and still transport up to 3 M⊙ yr-1 to the intergalactic medium, suggesting that thermal gas pressure is sufficient to power the multiphase wind without additional support from cosmic rays. We also show that the nuclear gas is hotter and faster than the plasma seen on larger scales,

suggesting a distinct origin for the latter.

▲ Abstract:
The automation of science is a long-standing ambition in artificial intelligence (AI) research. Although the community has made substantial progress in automating individual components of the scientific process, a system that autonomously navigates the entire research life cycle—from conception to publication—has remained out of reach. Here we present a pipeline for automating the entire scientific process end to end. We present The AI Scientist, which creates research ideas, writes code, runs experiments, plots and analyses data, writes the entire scientific manuscript, and performs its own peer review. Its ideas, execution and presentation are of sufficient quality that the manuscript generated by this AI system passed the first round of peer review for a workshop of a top-tier machine learning conference. The workshop had an acceptance rate of 70%. Our system leverages modern foundation models within a complex agentic system. We evaluate The AI Scientist in two settings: a focused mode using human-provided code templates as an initial scaffold for conducting research on a specific topic and a template-free, open-ended mode that leverages agentic search for wider scientific exploration. Both settings produce diverse ideas and automatically test, report on and evaluate them. This achievement demonstrates the growing capacity of AI for *** scientific contributions and signifies a potential paradigm shift in how research is conducted. As with any impactful new technology, there could be important risks, including taxing overwhelmed review systems and adding noise to the scientific literature. However, if developed responsibly, such autonomous systems could greatly accelerate scientific discovery.

▲ Abstract:
Magnetic fields can influence reactions involving spin-correlated radical pairs (SCRPs). This provides a mechanism by which both static and time-varying magnetic fields can affect living systems at the biomolecular level. However, an engineered SCRP system conferring magnetic sensitivity to a non-native biochemical process in a multicellular organism has not yet been demonstrated. Here we demonstrate control of SCRP dynamics using magnetic resonance in a live transgenic animal. We show that the emission of various red fluorescent proteins (RFPs), in the presence of a flavin cofactor, can be modified by a combination of static and radiofrequency magnetic fields applied near the electron spin resonance frequency. This effect was measured at room temperature both in vitro and in the nematode Caenorhabditis elegans, genetically modified to express the RFP mScarlet. These observations suggest that the magnetic field effects measured in RFP-flavin systems are due to quantum-correlated radical pairs with a coherence time larger than 4 ns. Our experiments demonstrate that radiofrequency magnetic fields can influence dynamics of reactions involving SCRPs in vivo, potentially enabling new methods for remotely controlling biomolecular processes, such as gene expression, and suggest broader potential for quantum tools in biology.

▲ Abstract :
Perovskite solar cells (PSCs) with power-conversion efficiencies comparable to established technologies hold huge promise for becoming the future photovoltaic technology, also given their versatility, low-cost and energy-efficient fabrication processes. However, PSCs are not stable under moderate reverse bias, an unavoidable situation under real-world operation, for instance, caused by partial shading of a module or installation with PSCs connected in series. Approaches to address this issue have focused on engineering the device architecture to enhance the breakdown voltage and mitigate the detrimental effects of reverse bias. Here we present a completely different approach that fully solves the reverse-bias issue. With our Memsol, we developed a new concept of a solar cell with an integrated memristor, which protects the solar cell and simultaneously works as a bypass element. The memristor is realized by area-selective deposition of an additional metal–insulator stack and shares the perovskite and electrodes with the solar-cell part. Reverse-bias and shading tests show that the Memsol remains stable and automatically toggles between a low-resistance bypass state and full-efficiency solar-cell operation, dependent on the illumination and bias conditions. We anticipate that our Memsol concept, which we demonstrated on a nine-cell string in the lab, will be implemented in large-scale modules, accelerating their commercialization and potentially *** external bypass diodes unnecessary.

▲ Abstract:
Effectively communicating worst-case projections of global future climate—hereinafter referred to as worst-case climate outcomes—is essential for risk assessment and developing robust adaptation strategies to global warming. Yet, current approaches for identifying spatially consistent climate outcomes are limited, with worst-case global climates typically communicated via the average of climate model projections at high global warming levels, such as 3 °C or 4 °C above the preindustrial era. Here we show that extreme global climate outcomes may occur even under moderate 2 °C warming for several sectors. For droughts in global key breadbasket regions, precipitation extremes over highly populated areas and fire weather extremes across forests, global climatic impact-drivers at 2 °C of global warming may turn out to be much more extreme than model-averaged projections at 3 °C or 4 °C warming. We derive these results by identifying sector-specific, spatially consistent potential high- and low-impact global climate outcomes through spatially averaging projected sector-relevant climatic impact-drivers across key global regions. Our approach can easily be adapted to a wide range of sectors to support the improvement of sector-specific climate risk assessment and to inform climate policy. As global warming approaches 1.5 °C, these findings underscore the urgency of rapid mitigation to limit warming well below 2 °C, as even a 2 °C world may entail severe impacts.

▲ Abstract:
ICarbon capture and storage (CCS) has the potential to help nations meet their Paris Agreement CO2 reduction commitments. The ability to capture CO2within mafic and ultramafic rocks through mineralization of carbon is an example of such a CCS technology, but large-scale deployment has yet to be achieved. Each geologic environment in the Earth’s crust requires a distinct carbon storage solution. Whereas some regions of the subsu***ce contain saline aquifers and sedimentary traps suitable for traditional carbon storage through the injection of high-pressure, dense CO2below impermeable caprocks, other regions may lack caprocks. In these regions, carbon storage is possible through the mineralization of injected water-dissolved CO2forming stable carbonate minerals through its reactions with reactive silicate rocks and minerals. A notable challenge to applying this process at scale is that it can require 20–50 times or more water than the mass of CO2stored. Here we report on an industrial-scale pilot project designed to find a carbon disposal solution for western Saudi Arabia. This arid region has large point-source CO2emitters, including petroleum refining and desalination facilities, but lacks saline aquifers and sedimentary traps. We find that a CO2injection approach based on the recirculation of subsu***ce fluids can eliminate the need for external water. Our results demonstrate the feasibility of carbon mineral storage in regions in which access to water resources may be limited.
