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: Dinoflagellates are a diverse group of microalgae utilized for various purposes. Cryopreservation is an effective method for their long-term preservation, with challenges in preserving larger species. This study explored the effects of cryoprotectant agents and freezing methods on three dinoflagellate species, with successful cryopreservation achieved for Breviolum sp. but not for V. rugosum and A. pacificum.

Summary: This study explores the use of TROPOMI's red SIF for detecting Karenia brevis, comparing it with the standard remote sensing HAB indicator MODIS-Aqua. The results show that red SIF provides more spatiotemporal fluorescence information than nFLH and can be used for detection under cloudy conditions, which improves early warning systems for harmful algal blooms.

Summary: Ecological models are important for predicting ecosystem responses to stresses, and their reliability depends on long records, skill assessments, and quantifying uncertainty. This study focuses on Lake Erie harmful algal blooms and enhances a Bayesian model using new information and a larger dataset. The model explains a significant portion of the variability in bloom size and performs better than previous forecasts.

Summary: In this study, 30 proteins containing the DOT1 domain were identified and analyzed, and it was found that the expression levels of some ApDOT1 genes were significantly influenced by light intensity and nitrogen. The enrichment of H3K79 methylation also showed a similar trend. Moreover, ApDOT1.9 protein was proven to have the function of catalyzing the methylation of H3K79 through homology analysis and in vitro methylation. The results suggested that ApDOT1 proteins and H3K79 methylation were involved in responding to harmful algal blooms-inducing conditions, providing basic information for further exploring the regulatory mechanism of histone methylation in A. pacificum rapid growth.

Summary: Researchers conducted a series of experiments to study the effects of toxic dinoflagellate on the feeding, reproduction, and toxin excretion of copepods. They found that the toxicity of the dinoflagellate affected the reproduction, toxin excretion, and feeding behavior of the copepods, indicating the significant impact of toxins on copepods.

Summary: This study compared the growth, phosphorus utilization, toxin production, and gene expression of Alexandrium pacificum under different phosphorus supply conditions. The findings revealed that the utilization strategies of organic and inorganic phosphorus differ, and organic phosphorus utilization in low phosphorus conditions may be a crucial factor driving bloom formation.

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: 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: Harmful algal blooms in water have become more frequent due to severe eutrophication and extreme climate. Photocatalysis is seen as an effective method for inactivating harmful algae. Recent research has focused on understanding the basic mechanisms and modifying techniques of photocatalytic materials for deactivating algae. The performance of various photocatalysts in terms of chlorophyll-a and cyanobacteria removal have been evaluated based on quantitative metrics such as quantum yields, space time yields, and figures of merit.
