Summary: The harmful algal bloom (HAB) issue is becoming more severe globally, impacting water supplies. In this study, the cell-free supernatant (CFS) of Bacillus was used to control HAB species, but the remaining nutrients in the water could cause the bloom to occur again. The study found that NB-CFS was more effective in inhibiting harmful cyanobacteria and promoting beneficial green algae.

Summary: Harmful algal blooms (HABs) are increasing globally, and the relationship between HAB aerosols and human health remains unclear. This review synthesizes current knowledge and identifies gaps in understanding this relationship. Some HAB aerosols have been linked to respiratory outcomes, but direct measurements of aerosol or toxin concentrations are lacking, and epidemiological studies are limited. Further research is needed to explore the health effects of other HAB species, dose-response relationships, effects of concurrent exposures, the impact of long-term exposures, and disparities in vulnerable populations.

Summary: Harmful algal blooms (HABs) have been increasing in the Eastern Chinese coastal seas (ECCS) due to the excessive nutrient inputs from land-based sources, leading to significant economic losses. This study used a watershed-coast-continuum concept to analyze the impact of land-based nutrient pollution on HAB development in the ECCS. Results showed a significant increase in the risk of diatom blooms and dinoflagellate blooms from the 1980s to 2000s, with dinoflagellates causing a larger spatial expansion of HAB risk than diatoms. Reductions in dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP) loading are necessary to prevent further nutrient accumulation in the ECCS.

Summary: Harmful algal blooms are a global threat to marine ecosystems and human health. This study used translatome sequencing to investigate the molecular mechanisms of the Prorocentrum donghaiense algae. Through analyzing the translatome and proteome, the study found that up-regulation of energy and material production pathways in phosphor-rich conditions led to exponential growth of the algae in HABs. The researchers also demonstrated that mild translation delay using low concentrations of cycloheximide can control algal blooms without harming other aquatic organisms or humans.

Summary: The study reveals that the toxic substances produced by toxic phytoplankton suppress the grazing population, giving both phytoplankton species an advantage and leading to irregular patterns in their seasonal growth. The dynamics of toxic phytoplankton blooms become more irregular and severe in the presence of high toxic effects, while non-toxic phytoplankton show annual blooms.

Summary: This study developed a cheap and eco-friendly cationic straw by etherifying wheat straw, which can efficiently dispose of harmful algal blooms (HABs). By aggregating HABs cells through charge neutralization, the cationic straw achieved a high harvesting efficiency. Unlike traditional salt-based flocculants, the HABs harvesting process with the cationic straw is a spontaneous and exothermic process mainly driven by physical forces.

Summary: Surface machining techniques such as cutting, rolling, and grinding were used to machine 304 austenitic stainless steels in order to enhance the hardening layer and corrosion resistance. Among the tested samples, the rolling sample exhibited the best surface quality with the lowest surface roughness and fewest defects. The rolling sample also displayed the highest degree of work hardening and corrosion resistance, attributed to the residual compressive stress and fewer micro-defects.

Summary: This study investigated the stacking fault energy and creep mechanism of a single-crystal nickel-based superalloy at different temperatures. The results revealed that the stacking fault energy increased with temperature and that the presence of element Ru significantly reduced the stacking fault energy compared to other elements in the alloy. The creep mechanism involved <110> super-dislocation shearing into the gamma ' phase below 850 degrees C, which could be decomposed into (a/3) <112> partial dislocations and super-lattice intrinsic stacking fault. However, above 850 degrees C, the resistance to dislocation decomposition increased, and the a <110> super-dislocation did not decompose when it cut into the gamma ' phase along the {111} plane.

Summary: We suggest using a femtosecond X-ray pulse to trigger Resonant Auger scattering (RAS) in a distorted molecule, which provides information on the core-valence electronic transition and impresses a rich fingerprint of the electronic structure and nuclear configuration. By controlling the amount of molecular distortion with varied time delay, the RAS measurements imprint both their electronic structures and changing geometries. This work showcases a new alternative pump-probe technique for mapping the core and valence dynamics with ultrashort X-ray probe pulses.

Summary: This study investigates the effects of fluid parameters - flow velocity, impact angle, and sand impact frequency - on the erosion-enhanced corrosion of 90/10 copper-nickel alloy. By combining computational fluid dynamics simulation, wire beam electrode technology, and electrochemical measurements, the researchers find that under different flow velocities, erosion-enhanced corrosion is dominated by either the impact angle or the flow velocity. However, at intermediate flow velocities, both parameters have noticeable effects. Furthermore, the addition of sand particles increases the corrosion current density without changing the effects of flow velocity and impact angle, indicating the significant influence of all three fluid parameters on the erosion-enhanced corrosion of the alloy.

Summary: A material extrusion (MEX) technology was developed for additive manufacturing of continuous carbon fiber-reinforced silicon carbide ceramic (C-f/SiC) composites. A slurry with high solid loading and viscosity was proposed based on rheological properties. Complex structures of C-f/SiC composites were printed using this MEX technique. Phenolic resin impregnation-carbonization process and reactive melting infiltration (RMI) were used to prepare samples with different C-f contents, with the highest bending strength and fracture toughness achieved at 1 K C-f content.

Summary: This study investigated the clinical outcomes of frozen-thawed blastocyst transfers derived from zygotes with no or one pronucleus (0PN or 1PN). The results showed that the developmental potential and clinical outcomes of 0PN and 1PN embryos were similar to those of 2PN embryos in both IVF and ICSI cycles. This suggests that 0PN and 1PN embryos from ICSI cycles can be transferred when there is an insufficient number of 2PN embryos.

Summary: Follicle developmental capacity and oocyte quality decline with advanced maternal age. Extracellular vesicles from human umbilical cord mesenchymal stem cells (HucMSC-EVs) have potential therapeutic effects on age-related ovarian dysfunction. In vitro culture (IVC) of preantral follicles is a useful method for understanding follicle development and improving female fertility. This study demonstrated that HucMSC-EVs can improve the growth and quality of aged follicles and oocytes in vitro through gene transcription regulation.

Summary: The inelastic squared form factors of valence-shell excitations in D2 were studied using high-energy electron scattering and theoretical calculations. Discrepancies were found between the experimental results and theoretical calculations for the B1Eu+ state and vibronic states of C1 pi u and EF1 sigma g+. This can be attributed to electronic-vibrational coupling and the failure of the first Born approximation at an incident electron energy of 1500 eV. The inelastic squared form factors of D2 were in good agreement with H2 and HD, indicating no isotope effect for electronic matrix elements in the momentum space.
