III. A new rival : H10N3Chinese scientists have isolated a strain ofH10N3 influenza virus from a patient inJiangsu province of eastern China, the firstcase of interspecies transmission of anavian H10N3 influenza virus to humans.COMICby KamakshiIV. Mystery of The Positron ExcessAccording to a recent study, cosmicrays while propagating through theMilky Way galaxy interact with matterproducing other cosmic rays,primarily electrons and theantimatter positrons, responsible forthe “positron excess” i.e., theunusual behavior of positronsbetween 10 and 300 GeV.ARTICLE ABSTRACTSThe AHEAD system uses an acceleratedevolution workflow for antibodyengineering via orthogonal DNAreplication in yeast cells that furthercombines autonomous genediversification with protein displaytechnology.READ MORE : click hereI.

II. Stress, suPAR and ageingInflammation is thought to serve as the keylink between stressful life events and itseffects on the health of an individual. In along term study, suPAR[soluble urokinasetypeplasminogen activator receptor ]emerged as a biomarker of systemicchronic inflammation.suPAR is product of uPAR cleavage and isreleased into blood, urine & CSF. suPARlevels reflect the activation status of theimmune system within the bodyElevated suPAR levels were observed inadults[age 45] who had experiencedstressful life events during the age of 38-44as well as those that had ACE(adversechildhood experiences).READ MORE : click hereIII. RNA knots of strength:a molecular shieldUnfolding a Zika virus xrRNA(exoribonuclease-resistantRNAs) with optical tweezersrevealed that it was the mostmechanically stable RNA yetobserved with unusual knot likestructures. The knot is formedby threading the 5′ end into athree-helix junction beforepseudoknot interactions closeda ring around it, mediated inpart by mechanical stressorsDOI:https://doi.org/10.1038/s41589-021-00829-zPheugopedius euophrys [plain tailed wrens]pairs sing in such synchronization, it seemsas if a single bird is the source.Recent research reveals that inhibitionsdriven by auditory feedback from the partneralong with the premotor activity used by eachindividual leads to such duets.It also suggests that when individuals interactin shared behavior, they act as a single entity,essentially "linking their brains together".READ MOREQuestion quests1: A virulent beautyXY is the folding of X to create arbitrary nanoscale two- and three-dimensional shapes. Itinvolves folding of a single long strand of viral X aided by multiple smaller "staple" strands.These shorter strands bind the longer in various places forming a pre-defined two- and three- dimensional shape.This technique has progressed past an art form and has applications in drug delivery systems,circuitry in plasmonic devices etc. Identify the technique.
