Researchers discover new class of ribosomal peptide with hemolytic activity UofIllinois NatureComms
NRRL B-3501 were recovered on ISP2 agar medium at 37 °C until colony appears . A single colony was inoculated into 5 mL ISP2 liquid medium as seed culture and grown at 37 °C 250 rpm until saturation . 1 mL of the seed culture was then transferred into 50 mL fresh ISP2 liquid medium and cultivated for 18-20 h. Cells were then harvested by centrifugation at 3000 × g for 15 min and resuspended in 12 mL of cell resuspension buffer . Cell lysis enzymes , and 0.
Guide RNA was prepared through in vitro transcription. Briefly, 5 µM forward and reverse template oligonucleotides were mixed in NEBuffer 3.1. The mixture was incubated at 98 °C for 5 min, followed by slowly reducing the temperature with the rate of 0.1 °C/s until 10 °C was reached. A 2 µL aliquot of the annealed oligonucleotides was used as template for in vitro RNA transcription by HiScribe T7 quick high yield RNA Synthesis kit .
The digested genomic DNA was assembled with DNA receivers by the T4 DNA polymerase exo + fill-in method. DNA receivers were PCR amplified using primers listed in Supplementary Table. A 15 µL assembly reaction consists of 3–3.75 µg of digested genomic DNA, 15 ng of DNA receiver amplified from plasmid pBE44, 35 ng of DNA receiver amplified from plasmid pBE45, 1.5 µL of NEBuffer 2.1, and 0.75 U of T4 DNA polymerase.

Future Indian Ocean warming patterns - Nature CommunicationsStrong negative climatological air-sea interactions effectively damp warming over the eastern Indian Ocean, resulting in weakening of the winds therein. This, in turn, changes the strength of ocean currents, which is considered as the primary mechanism responsible for modulating warming patterns.

Eoarchean and Hadean melts reveal arc-like trace element and isotopic signatures - Nature CommunicationsGeochemical analysis indicates a formational regime for Jack Hills zircons that is lithologically diverse and chemically similar to modern arcs. This depicts complicated geodynamics of the early Earth, which is currently proposed by many as stagnant-lid.

Hybrid magnonics in hybrid perovskite antiferromagnets - Nature CommunicationsRecently there has been interest in exploring the coupling between magnons for use in information processing, however, this is hampered by the fact that such coupling is forbidden due to the different parity of the acoustic and optical magnons. Here, Comstock et al show that the interlayer Dzyaloshinskii–Moriya-Interaction in a layered hybrid antiferromagnet can allow for strong coupling between the acoustic and optical magnons, offering a pathway for magnon coherent information processing.

Mutation in glutamate transporter homologue GltTk provides insights into pathologic mechanism of episodic ataxia 6 - Nature CommunicationsEpisodic ataxias (EAs) are rare neurological conditions that cause motor impairment. Here the authors investigated the molecular mechanism of such a pathological condition caused by a mutation of a conserved proline into arginine residue.
