2+ hour, 36+ min ago  (458+ words) Astrobiology Web Our work also introduces LiteratOmics, a new framework that combines literature mining, natural language processing, and AI to transform scientific publications into structured, searchable, and interconnected knowledge. The platform supports researchers, educators, students, and citizen scientists while promoting…...

1+ day, 4+ hour ago  (195+ words) We introduce neutrino interactions into the autocatalytic chemical reactions in a far-from-equilibrium noise-induced system. These interactions create a directional bias between L and D enantiomers in the racemization reactions, which is amplified by autocatalysis and stochastic fluctuations. Chemical scheme of…...

1+ day, 3+ hour ago  (257+ words) The research helps explain a long-standing biological mystery: why cyanobacteria invest energy in forming flocs despite the apparent cost to their growth. The findings suggest the behaviour is an evolved defense mechanism that could have implications extending from microbial ecology…...

5+ day, 4+ hour ago  (265+ words) Astrobiology Web [Fundamental Research] Understanding the origin of life requires explaining how abiotic molecules transitioned into the first living systems within plausible geological settings. Increasing evidence suggests minerals as active participants in prebiotic evolution. By adsorbing and concentrating reactants, catalyzing…...

1+ week, 2+ day ago  (150+ words) [biorxiv.org] Saturation mutagenesis is a powerful tool for understanding and engineering the function of biological systems, and has been applied successfully to characterize the mutational landscape of individual proteins and genetic loci. However, it has not been applied at…...

3+ week, 1+ day ago  (168+ words) Terrestrial algae play a critical, yet often overlooked, role in the functioning of biological soil crusts (biocrusts), which are considered microecosystems, particularly in extreme environments. This study investigated the ecophysiological traits of green algae isolated from the grit crust—a…...

1+ mon, 1+ day ago  (232+ words) Next, Zaccaria studied several well known human pathogens, such as the bacterium Klebsiella pneumoniae, which can cause pneumonia. He observed that these pathogens shrank after a simulated trip to Mars, yet survived it. In laboratory experiments, immune cells from human…...
