Article Synopsis
- Polycyclic aromatic hydrocarbons (PAHs) are harmful organic pollutants resulting from incomplete combustion of organic material, posing risks to ecosystems and human health, which necessitates effective remediation methods.
- This study explores the potential of combining nanomaterials with bioremediation techniques, finding that nano-bioremediation improves PAH removal in liquid samples by 18.9% and in soil samples by 14.3% compared to traditional bioremediation alone.
- Various strategies for nano-bioremediation are discussed, including microbial degradation and enzyme enhancement, along with eco-friendly approaches using biogenic nanomaterials to tackle PAH pollution.
Article Synopsis
- - The study examined playground soil contamination in Khagra, India, focusing on potentially toxic elements (PTEs) like As, Cd, Cu, and Zn that pose health risks, particularly respiratory and gastrointestinal issues for children.
- - Sequential extraction methods revealed Sn as the most contaminated element, while other PTEs exhibited moderate contamination levels; the highest concentrations typically occurred in the iron and manganese oxide-bound fraction.
- - The risk assessment indicated moderate health risks associated with several PTEs, while mobility factors showed the ease with which these contaminants could be absorbed into the human body, highlighting the potential dangers of contaminated playground soils.
Degradation, detoxification, or removal of the omnipresent polycyclic aromatic hydrocarbons (PAHs) from the ecosphere as well as their prevention from entering into food chain has never appeared simple. In this context, cost-effective, eco-friendly, and sustainable solutions like microbe-mediated strategies have been adopted worldwide. With this connection, measures have been taken by multifarious modes of microbial remedial strategies, i.

Aquatic weeds have exceptionally high reproduction rates, are rich in cellulose and hemicellulose, and contain a negligible amount of lignin, making them an ideal crop for the next generation of biofuels. Previously reported studies proposed that water hyacinth, water lettuce, common duckweeds, and water spinach can be managed or utilized using different advanced techniques; from them, anaerobic digestion is one of the feasible and cost-effective techniques to manage these biowastes. The present study was carried out to investigate the potential of utilizing four common aquatic weed species (water hyacinth, water lettuce, common duckweeds, and water spinach) as substrates for anaerobic digestion in order to produce biogas for use in biofuels.

- Serial dependence is when people perceive stimuli to be more similar or different from previous stimuli than they actually are, influenced by both sensory interactions and cognitive factors like expectations.
- An experiment tested how expectations affect serial dependence by presenting sequences of gratings that either followed a predictable pattern or varied randomly, revealing that observers were more accurate when stimuli matched their expectations.
- The results showed that responses were biased away from the previous stimulus when expectations were met (repulsive dependence) but biased towards it in unpredictable situations (attractive dependence), highlighting the complex interaction between expectation and stimulus perception.
Article Synopsis
- A 14-year-old boy was admitted to the hospital due to difficulty opening his mouth and a burning sensation when eating spicy food.
- The examination revealed blanching of the oral mucosa and inability to stick out his tongue.
- This case is significant as it emphasizes the rare occurrence of oral submucous fibrosis in young patients linked to long-term use of gutkha, a mixture of betel nut and tobacco.
