Most studies on ammonia electrolysis have focused on anion exchange membranes (AEMs), which face limitations in operating conditions, such as pH and ammonia concentration. This study introduces a novel concept of an ammonia electrolysis cell (AEC) utilizing a Zirfon separator capable of operating under high pH and ammonia concentrations. The Zirfon-based AECs achieve a peak current density of 915 mA cm, representing the highest reported value in AEC literature.

Article Synopsis
  • The rise of antibiotic-resistant bacteria (ARBs) poses a significant global health threat due to increasing infections and mortality rates.
  • The study focused on using a deep-learning model to identify antimicrobial peptides (AMPs) from spider venom, with a promising candidate, PA-Win2, showing strong effectiveness against multidrug-resistant strains.
  • PA-Win2 not only inhibited bacterial growth and biofilm formation but also altered gene expression linked to bacterial survival, suggesting its potential as a new treatment for ARB infections.

Cancer, recognized as a primary cause of death worldwide, has profound health implications and incurs a substantial social burden. Numerous efforts have been made to develop cancer treatments, among which anticancer peptides (ACPs) are garnering recognition for their potential applications. While ACP screening is time-consuming and costly, in silico prediction tools provide a way to overcome these challenges.

Colorectal cancer (CRC) is one of the top five most common and life-threatening malignancies worldwide. Most CRC develops from advanced colorectal adenoma (ACA), a precancerous stage, through the adenoma-carcinoma sequence. However, its underlying mechanisms, including how the tumor microenvironment changes, remain elusive.

Article Synopsis
  • Ion channels are potential drug targets for various disorders, but screening ion channel-modulating peptides (IMPs) is costly and time-intensive, making in-silico approaches like PrIMP more appealing.
  • PrIMP employs multi-task learning and transfer learning to enhance prediction accuracy for IMPs targeting sodium, potassium, and calcium channels, as well as nicotine acetylcholine receptors.
  • The model achieved impressive F1 scores, indicating strong performance in predicting IMPs, and the dataset along with the model can be accessed online for further research.

Three chitinolytic, Gram-negative, light pink, capsule-forming, rod-shaped bacterial strains with gliding motion (MYSH2, MJ1a and dk17) were isolated from seashells, soil and foxtail, respectively. Phylogenetic analysis of the 16S rRNA gene sequences and concatenated alignment of 92 core genes indicated that strains MYSH2, MJ1a and dk17 were novel species of the genus and exhibited a high 16S rRNA sequence similarity (i.e.

A Gram-negative, moderately halophilic bacterium, designated as strain Y3S6, was isolated from a surface seawater sample collected from Dongangyoeng cave, Udo-myeon, Jeju-si, Jeju-do, Repulic of Korea. Cells of strain Y3S6 were aerobic, rod-shaped, non-sporulated, yellow, catalase- negative, oxidase-negative and motile with one polar flagellum. Growth of strain Y3S6 occurred at 15-40 °C (optimum: 25-30 °C), at pH 6.

As major components of spider venoms, neurotoxic peptides exhibit structural diversity, target specificity, and have great pharmaceutical potential. Deep learning may be an alternative to the laborious and time-consuming methods for identifying these peptides. However, the major hurdle in developing a deep learning model is the limited data on neurotoxic peptides.

A gamma radiation-resistant and pink-pigmented bacterial strain, designated as 17Sr1-39, was isolated from a gamma ray-irradiated soil sample collected in the Republic of Korea. Cells were Gram-stain-negative, strictly aerobic, flagellated, asporogenous, rod-shaped and methylotrophic. Results of 16S rRNA gene sequence analysis showed that strain 17Sr1-39 was phylogenetically related to PR1016A (97.
