Summary: In the current radiation protection system, the linear no-threshold extrapolation model is used to determine preventive measures and occupational exposure limits for ionizing radiation. However, increasing evidence suggests that this model poorly predicts biological responses to low-dose exposure. Furthermore, studies have shown the presence of hormetic dose response curves correlated to low exposure to ionizing radiation. Rating: 7/10

Summary: In 2011, ICRP recommended reducing the occupational equivalent dose limit for the lens of the eye and setting new dose thresholds and occupational dose limits for radiation-induced cataracts. However, these recommendations are mainly based on epidemiological evidence, with limited biological and mechanistic evidence available for doses under 2 Gy.

Summary: Hormesis refers to the beneficial effects of low doses of certain agents while higher doses are detrimental. Research suggests that low-dose ionizing radiation may have hormetic effects on longevity in certain animal models, but caution should be exercised in introducing LDIR therapy for age-related disorders. Clinical trials assessing the potential benefits of LDIR treatments should be prioritized considering the significant implications for treatable age-related diseases.

Summary: By analyzing the radar observation data from the Urumqi Satellite Receiving Station, researchers have found that the mass balance of the Yabulangsha Glacier has undergone significant changes over time. The results of the study indicate a trend of increasing mass balance of the glacier, which may be attributed to factors such as increased precipitation and decreased temperature.

Summary: This paper identifies six major conceptual scientific errors made by Hermann Muller and explains how these errors led to the development of the linear no-threshold (LNT) dose response, which has been widely used worldwide for cancer risk assessments. The paper highlights the significant influence Muller had in the environmental movement, impacting risk assessment policies that are still in use even decades after his death. It also supports current research showing the limitations of the LNT model for cancer risk assessment.

Summary: The current system of radiological protection relies on the linear no-threshold (LNT) hypothesis, which assumes that any exposure to ionizing radiation poses a cancer risk. However, accumulated evidence suggests that low doses of radiation do not cause harm and may even promote health. This review discusses epidemiological analyses, clinical trials, and animal studies that support the presence of a threshold and departure from linearity for radiation effects. Despite the scientific implausibility and negative social consequences, the LNT tenet persists.

Summary: The challenges in the food/non-food applications of starch stem mainly from its low stability under harsh processing conditions, excessive retrogradability, and limited applicability. These drawbacks have been addressed through starch modification. Due to the increasing concerns about the potential side effects of chemical modification, scientists have turned their attention to the development of physical modification techniques. Ionizing and non-ionizing radiations have been introduced as potent physical strategies to modify starch, providing new outstanding attributes to the modified product. Ionizing radiations can induce depolymerization or cross-linking/grafting reactions in the starch medium, while non-ionizing radiations can modify starch attributes by altering granule morphology/architecture and reorienting/rearranging the molecular order of starch amorphous/crystalline fractions.

Summary: One of the challenges in aging research is to understand how genetics and environmental factors interact to determine the chances of reaching extreme human lifespan in good health. Epigenetic mechanisms provide an explanation for this interaction and the long-term effects of lifestyle on aging. The theory of inflammaging suggests that chronic low-grade inflammation plays a crucial role in age-related diseases and mortality. Studies on centenarians have shown that healthy individuals can upregulate anti-inflammatory responses to cope with inflammaging. Genetic factors and the ability to remodel metabolic pathways are also important for healthy aging. The concept of antifragility, which refers to the ability of complex systems to perform better under stress, may provide insights into the heterogeneous nature of the aging process and its relationship with inflammation.

Summary: This study investigates the changes in polymer structure after exposure to ionizing radiation using synchrotron x-rays. The results show that the ionizing radiation induces a reaction cascade that continues long after removal of the x-ray beam, and the reaction rate is controlled by the exposure time. These findings provide insights into the stability of conjugated polymers in the presence of reactive diluents and ionizing radiation, and offer new possibilities for forming graft copolymers.

Summary: The total ionizing dose (TID) effect is a major factor contributing to the degradation/failure of semiconductor devices under high-energy particle irradiation. A dynamic model was developed to understand the threshold voltage shifts induced by TID in silicon-based metal-oxide-semiconductor (MOS) devices by solving rate equations and Poisson's equation simultaneously. The calculated charged defect distribution and electric field under different TIDs matched experimental results. TID alters the electric field at the Si/SiO2 interface by accumulating oxide charged defects nearby, leading to threshold voltage shifts accordingly. As TID increases, the oxide charged defects reach saturation and the electric field follows a universal 2/3 power law. Analyzing the impact of TID on the interfacial electric field, we recommend improving the radiation-hardened performance of devices by selecting a thin oxide layer with high permittivity and operating at high gate voltages.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.
