Article Synopsis
  • Uranium pollution in aquatic ecosystems threatens organisms, but its metabolism and toxicity along food chains are not fully understood.
  • An artificial aquatic ecosystem study showed that uranium affects algae by causing cell deformation and reducing growth, and this toxicity varies based on how fish are exposed to uranium.
  • High uranium levels significantly increase toxicity risks for fish when ingested through contaminated algae, while a portion of uranium is reduced to less harmful forms in both algae and fish during accumulation, indicating complex interactions in the food chain and potential risks for human consumption of contaminated aquatic products.

Article Synopsis
  • Dietary exposure to methylmercury (MeHg) is harmful to human cognition, particularly through rice consumption, which is a key source of MeHg.
  • Researchers found a unique pathway in rice plants that converts MeHg to inorganic mercury and then releases it as gaseous mercury without needing light or microorganisms.
  • This pathway prevents significant increases in MeHg levels in rice grains, which could otherwise lead to minor IQ drops in newborns and substantial economic losses globally.

Sulfur has a high affinity for mercury (Hg) and can serve as effective treating agent for Hg pollution. However, conflict effects between reducing Hg mobility and promoting Hg methylation by sulfur were found in recent studies, and there is a gap in understanding the potential mechanism of MeHg production under different sulfur-treated species and doses. Here, we investigated and compared the MeHg production in Hg-contaminated paddy soil and its accumulation in rice under elemental sulfur or sulfate treatment at a relatively low (500 mg·kg) or high (1000 mg·kg) level.

The imbalance of nutrient elements in paddy soil could affect biogeochemical processes; however, how the key elements input influence microbially-driven conversion of mercury (Hg) to neurotoxic methylmercury (MeHg) remains virtually unknown. Herein, we conducted a series of microcosm experiments to explore the effects of certain species of carbon (C), nitrogen (N) and sulfur (S) on microbial MeHg production in two typical paddy soils (yellow and black soil). Results showed that the addition of C alone into the soils increased MeHg production approximately 2-13 times in the yellow and black soils; while the combined addition of N and C mitigated the C- promoting effect significantly.

The co-exposure of antibiotics has important effects on antibiotic resistance genes (ARGs) and microbial community aggregation in wastewater treatment plants (WWTPs). However, it is unclear whether differences in historical antibiotic exposure stress can determine responses of microbes and ARGs to combined antibiotics. By selecting a high concentration (30 mg·L) of sulfamethoxazole (SMX) and trimethoprim (TMP) as historical exposure stress conditions, the effects of SMX and TMP-combined pollution on ARGs, bacterial communities, and their interactions were explored in short-term experiments.

OX40 (CD134, TNFRSF4) is a member of the tumor necrosis factor receptor superfamily that can be activated by its cognate ligand OX40L (CD252, TNFSF4) and functions as a pair of T cell costimulatory molecules. The interaction between OX40 and OX40L (OX40/OX40L) plays a critical role in regulating antitumor immunity, including promoting effector T cells expansion and survival, blocking natural regulatory T cells (T) activity, and antagonizing inducible T generation. However, current OX40 agonists including anti-OX40 monoclonal antibodies (aOX40) have serious side effects after systemic administration, which limits their clinical success and application.

As a major entry point of mercury (Hg) to aquatic food webs, algae play an important role in taking up and transforming Hg species in aquatic ecosystems. However, little is known how and to what extent Hg reduction, uptake, and species transformations are mediated by algal cells and their exudates, algal organic matter (AOM), under either sunlit or dark conditions. Here, using (CV) as one of the most prevalent freshwater model algal species, we show that solar irradiation could enhance the reduction of mercuric Hg(II) to elemental Hg(0) by both CV cells and AOM.
