title: Gravity Imaging Radio Observer (GIRO) for Planetary Science and Mission Opportunities

description: The Gravity Imaging Radio Observer (GIRO) is a high-performance, battery-powered radio probe 16 designed to be released in the proximity of a target planetary body to study its gravitational 17 variations. Using the host spacecraft’s communications system, the GIRO probes will receive and 18 transmit a coherent carrier signal back to a host spacecraft, providing high-precision range-rate 19 data with accuracy ≤1 μm/s at 60-s count time, which is 10–100 times better than the performance 20 of conventional ground-based radiometric data. GIRO is spin-stabilized, which significantly 21 reduces non-gravitational perturbations, making it ideal for acquiring clean gravitational signals 22 for exploring planetary interiors. Additionally, the use of a specifically designed, carrier-only, 23 analog transponder makes GIRO low-cost. Furthermore, a host spacecraft can release multiple 24 GIROs, reducing risk when exploring hazardous environments. In this paper, we describe the 25 GIRO probe and deployer design and present scenarios where GIRO enables gravity 26 measurements that would be challenging to achieve with conventional approaches

title: Isoprene Emissions, Oxidation Chemistry and Environmental Impacts

description: Isoprene emissions can affect the oxidizing capacity of the atmosphere and are likely to increase with an increase in the world’s biomass. The emission of isoprene is strongest in tropical forested regions, suggesting a major portion of tropospheric chemistry occurs in the tropics. As well as deforestation and reforestation having a direct impact on the world’s climate through land cover, there is also an indirect environmental impact (e.g., global warming, air pollution) through the resulting change in isoprene emissions. Previously, incomplete understanding of isoprene oxidation chemistry caused a model- measurement breakdown for concentrations of HOx radicals observed over certain low- NOx regions, such as the pristine Amazon rainforest. Over the last decade, however, understanding of isoprene oxidation chemistry has been vastly improved. Numerous research studies have provided evidence for the involvement of 1,6-H and 1,5-H shift reactions in the isoprene oxidation mechanism, which increases the level of HOx recycling that occurs. As well as helping to reduce the model-measurement breakdown observed, the updated isoprene oxidation mechanism affects the tropospheric burdens of other species, including carbon monoxide (CO), methane (CH4), ozone (O3), organic peroxides (ROOH), secondary organic aerosol (SOA), and organic nitrates (RONO2). There are still gaps in the understanding of the impacts and oxidation chemistry of isoprene emissions, which this literature review identifies and discusses. In the future, there is still much scope for further research, including modeling future reforestation scenarios with isoprene emissions and their impacts on both global and regional scales.

title: Modelling the effect of volcanic outgassing of sulphur on early Martian surface temperatures using a 3-D Global Climate Model

description: Around the time of the transition from the Late Noachian to the Early Hesperianeras (~3.6 Gya), Mars was predicted to have been both volcanically active, andhave sustained a climate warm enough to melt liquid water on its surface episodicallydespite a faint young sun. The effect of volcanic outgassing on the climateof early Mars and its ability to raise temperatures above the melting point of waterhas, however, been disputed, with a major uncertainty being the timescalesover which the greenhouse effect of outgassed sulphur dioxide (SO2) and hydrogensulphide (H2S) can warm the atmosphere of Mars before they react to formH2SO4 and S8 aerosols which act to cool the surface of Mars. We have developedthe first 3-D model of the Martian sulphur cycle from source to sink that includesoutgassing of SO2, H2S and S2 from the surface, the formation of H2SO4 and S8through atmospheric chemistry, and the condensation and deposition of H2SO4and S8 to the surface. We confirm the results of Tian et al. (2010, EPSL 295,412-418) and find that the warming effect of volcanically outgassed SO2 and H2Son the Martian atmosphere is negligibly short, instead resulting in a net coolingof the Martian surface over timescales of 3-4 years near the equator and severaldecades at the poles. Conversely, sufficient outgassing of SO2 can instead result inatmospheric collapse, which may have ended any prior warm period for hundredsof thousands of years.

title: Injection locking of Rydberg dissipative time crystals

description: Non-equilibrium Rydberg gases exhibit exotic many-body phases stabilized by the interplay of coherent interactions and dissipation. Strong Rydberg interactions drive sustained limit cycle oscillations, whose robustness, long-range temporal order, and spontaneous time-translation symmetry breaking establish a dissipative time crystal (DTC). Collective self-entrainment in driven ensembles leads to global synchronization and a dominant oscillation frequency. Here, injection locking of a Rydberg DTC is demonstrated using a radio-frequency (RF) electric field that gradually pulls the intrinsic oscillation toward the injected frequency. Above a critical threshold, full synchronization occurs, with the locking bandwidth scaling linearly with RF amplitude. This includes synchronization of higher-order harmonics, revealing entrainment of the system’s nonlinear temporal dynamics. The phenomenon parallels injection locking in classical nonlinear systems, but emerges here in a strongly interacting quantum medium. This approach establishes a new method for stabilizing and controlling quantum temporal order, with applications in precision sensing, quantum metrology, and timekeeping.

title: The relative constraining power of the high-𝑧 21-cm dipole and monopole signals

description: The 21-cm background is a promising probe of early star formation and black hole activity. While a slew of experiments on the ground seek to detect the 21-cm monopole and spatial fluctuations on large ∼ 10 arcminute scales, little work has been done on the prospects for detecting the 21-cm dipole signal or its utility as a probe of early galaxies. Though an intrinsically weak signal relative to the monopole, its direction is known well from the cosmic microwave background and wide-field surveys, plus as a relative measurement the dipole could help relax instrumental requirements. In order to understand the constraining power of the dipole, in this work we perform parameter inference on mock datasets that include the dipole, monopole, or both signals. We find that while the monopole does provide the best constraints for a given integration time, constraints from a dipole measurement are competitive, and can in principle constrain the cosmic star formation rate density and efficiency of X-ray photon production in early 𝑧 ∼ 15 galaxies to better than a factor of ∼ 2. This result holds for most of the available prior volume, which is set by constraints on galaxy luminosity functions, the reionization history, and upper limits from 21-cm power spectrum experiments. We also find that predictions for the monopole from a dipole measurement are robust to different choices of signal model. As a result, the 21-cm dipole signal is a valuable target for future observations and offers a robust cross-check on monopole measurements.

title: Europa Clipper Mission Design: Analysis of Probability of Impact Requirements

description: To explore the habitability of the Jupiter moon Europa, NASA launched Europa Clipper on October 14, 2024 on a Mars-Earth gravity assist trajectory to Jupiter. Once in Jupiter orbit, Europa Clipper will then perform a complex trajectory (moon tour) with more than 50 Europa flybys. The launch, interplanetary trajectory, and moon tour are designed to meet NASA Planetary Protection requirements, and to reduce the probability of impact of the spacecraft with the Jovian moons, Earth, Mars, and Earth orbiting objects. This paper focuses exclusively on the probability of impact requirements compliance computation and mitigation for the Europa Clipper mission.

title: A family cluster of <i>Brucella abortus</i> infections possibly due to contact with a sika deer in Northeast China

description: Brucellosis is one of the most common zoonotic diseases worldwide. Although deer are reportedly infected by <i>Brucella</i> spp., deer-associated brucellosis cases have been rare. In this study, two patients in Heilongjiang Province, Northeast China, were diagnosed with brucellosis. They have contacted a sick sika deer before onset which was bought from another province, but have no contact with other infection sources. Molecular genotyping indicated that both were infected with <i>Brucella abortus</i>. This might be the first human cases caused by deer-associated <i>B. abortus</i> strains despite the frequent reports of <i>B. abortus</i> in deer. The role of deer in the transmission of <i>B. abortus</i> should be taken into consideration. Brucella is a group of bacteria that infect domestic and wild animals. Humans can become infected if they have contact with an infected animal. Brucella have been frequently detected in deer, but the species <i>Brucella abortus</i> has never been reported to be transmitted from deer to humans. In this study, we report two patients from one family that were infected with Brucella abortus. We found that both had been in contact with a sick sika deer with no other possible sources of infection. This may be the first report that Brucella abortus can be transmitted from deer to humans. People who come into contact with deer or other animals should be aware of this potential risk.

title: Study of the mechanical and calorimetric properties of cement mortar incorporating thermally treated marine sediments

description: Dredging marine sediments generates millions of tons of waste annually, posing a major environmental and economic challenge. Reusing these materials in civil engineering offers a sustainable alternative for construction resources. This study investigates the potential of incorporating raw and heat-treated marine sediments from Algerian ports as partial replacements for CEM I 52.5 Portland cement at substitution rates of 10%, 20%, 30%, and 40%. The mechanical and physical properties of the resulting mortars were evaluated. Results show that compressive strength decreases with increasing sediment content; however, mortars with 10% substitution display strengths comparable to the reference mix, likely due to the sediments' reactivity with lime released during hydration. The consistency of mortar containing calcined marine sediments at substitution rates of 10% to 30% exhibits an accelerated initial setting time, while its final setting time is delayed. These initial and final reactivities can be attributed to variations in the processes of the pozzolanic reaction and cement hydration. Analysis of the heat of hydration further confirms pozzolanic reactions and latent hydraulic activity in the treated sediments, highlighting their potential for sustainable cement-based applications.

title: Tracking <i>bla</i><sub>CTX-M</sub> transmission through transposable elements in uropathogenic and commensal <i>E. coli</i>

description: To investigate the nucleotide sequences associated with transposable elements carrying bla<sub>CTX-M</sub> allelic variants as potential markers for the transmission of antimicrobial resistance genes between domestic animals, humans and the environment. We conducted whole-genome sequencing and analyzed the nucleotide sequences of most abundant bla<sub>CTX-M</sub> allelic variants (bla<sub>CTX-M-27</sub>, bla<sub>CTX-M-55</sub>, and bla<sub>CTX-M-65</sub>) in commensal Escherichia coli (<i>n</i> = 20) from household members in Quito and uropathogenic E. coli (UPEC) (<i>n</i> = 149) isolated from nine clinics in Quito, Ecuador. The Ecuadorian commensal <i>E. coli</i> and UPEC displayed identical nucleotide sequences surrounding the <i>bla</i><sub>CTX-M</sub> gene and the synteny was similar to those found in other parts of the world; however phylogenetic analysis indicated that the genetic environments in Ecuadorian isolates were unique. These findings suggest that the nucleotide sequences flanking the bla<sub>CTX-M</sub> genes may be useful for resolving ARG transmission pathways, especially inter-regional analyses. Bacteria can share small bits of DNA with each other using a type of DNA vehicle, known as a plasmid. The intestinal bacteria of domestic animals can also spread to humans. Some of these bacteria may share genes with human bacteria that make them resistant to antibiotics. It is hard to know how many of these genes move from animal to human bacteria because they are linked to pieces of DNA that let them jump around inside bacteria. This makes it harder to track how resistance genes spread. This study looks at one type of resistance gene called <i>bla</i><sub>CTX-M</sub> which makes bacteria resistant to antibiotics called cephalosporins, used to treat serious infections. We found that the DNA around this gene was the same in bacteria from both humans and domestic animals in Quito, Ecuador. However, the DNA was different from what is found in other parts of the world. We suggest that this DNA near the <i>bla</i><sub>CTX-M</sub> gene could help us understand how antibiotic resistance spreads between animals and humans in different regions.

title: Akdeniz Depremleri ve 6 Şubat İlişkisi: Bilimsel Gerçekler ve Yanlış Algılar

description: 12 Kasım 2025 tarihinde Paphos (Baf) açıklarında kısa süre içinde ardı ardına meydana gelen Mw 5.2, 4.8 ve 4.2 büyüklüğündeki depremler, kamuoyunda ve bazı çevrelerde "6 Şubat Kahramanmaraş depremlerinin devamı" şeklinde yorumlandı. Ancak bu yorumlar, deprem biliminin temel prensiplerine ve tektonik gerçeklere aykırıdır. Depremler, çevresindeki fay hatlarına belirli bir mekanik stres (gerilme) aktarabilir. "Stres aktarımı" veya "tetikleme" olarak bilinen bu olayın iki temel sınırlaması vardır:

Mesafe sınırı: Stres aktarımı genellikle birkaç on kilometre, nadiren 100 km'ye kadar etkili olabilir. Yüzlerce kilometre ötedeki bölgeleri etkilemesi fiziksel olarak mümkün değildir çünkü kabuk içindeki stres dağılımı bu mesafelerde sıfıra yaklaşır.

Zaman sınırı: Tetikleme etkisi haftalar, aylar, bazen birkaç yıl gibi kısa bir süre içinde kendini gösterir.

Kahramanmaraş merkezli depremler, Doğu Anadolu Fay Zonu'nda meydana geldi. Bu fay sistemi, Anadolu levhasının Arabistan levhasına göre hareketinden kaynaklanan doğrultu atımlı bir sistemdir. Paphos açıklarında meydana gelen depremler ise Helenik Yayı veya Kıbrıs Yayı adı verilen tamamen farklı bir tektonik sistemin parçasıdır. Bu sistem:

- Afrika levhasının kuzeye doğru Anadolu levhasının altına daldığı (subdüksiyon) süreçten kaynaklanır

- Girit'ten başlar, Rodos ve Kıbrıs güneyi boyunca uzanır, Hatay açıklarında sonlanır

- Dalma-batma zonundaki gerilme birikimlerinin doğal sonucudur

Kahramanmaraş ile Paphos açıkları arasındaki mesafe yaklaşık 480-550 km'dir. Bu kadar uzak bir mesafede doğrudan stres aktarımı fiziksel olarak mümkün değildir. İki sistem arasında tektonik bağlantı bulunmamaktadır.
