During an archaeological survey conducted in February, researchers from the Maritime Encounters program at the University of Gothenburg, Sweden, identified six previously unregistered Bronze Age mines in Extremadura, southwestern Spain. The discoveries may represent a crucial piece of the puzzle in understanding the origin of the metal used in Scandinavian Bronze Age artifacts.
Even though farmers have been dealing with rice stink bugs as pests since the 1880s, entomologists are still getting to know them at the genetic level. A first-of-its-kind study published on the genetics of rice stink bugs offers clues that could shape the battlefront on insecticide resistance for a tiny creature that costs Arkansas farmers millions of dollars a year. Rice and grain sorghum are the main economic crops, yet the bug feeds on many kinds of plants.
New research profiles mitochondrial circular RNAs in Peripheral Blood Mononuclear Cells (PBMCs) from young and old human cohorts and probes how mitochondrial circRNAs and the mitochondrial RNA-binding protein GRSF1 relate to mitochondrial metabolism and cellular senescence. The study was led by first author Hyejin Mun from the University of Oklahoma—with corresponding authors Je-Hyun Yoon from the University of Oklahoma and Young-Kook Kim from Chonnam National University Medical School— and is published in the journal Aging.
