Microphysical and kinematic processes associated with anomalous charge structures in isolated convection.

J Geophys Res Atmos 2018 Jun 30;123(12):6505-6528. Epub 2018 May 30.

National Aeronautics and Space Administration (NASA) George C. Marshall Space Flight Center, Huntsville, Alabama, United States of America (USA).

Microphysical and kinematic characteristics of two storm populations, based on their macroscale charge structures, are investigated in an effort to increase our understanding of the processes that lead to anomalous (or inverted charge) structures. Nine normal polarity cases (mid-level negative charge) with dual-Doppler and polarimetric coverage that occurred in northern Alabama, and six anomalous polarity cases (mid-level positive charge) that occurred in northeastern Colorado are included in this study. The results show that even though anomalous polarity storms formed in environments with similar instability, they had significantly larger and stronger updrafts. Read More

Points & Pearls: Electrical injuries in the emergency department: an evidence-based review

Emerg Med Pract 2018 Nov 1;20(Suppl 11):1-2. Epub 2018 Nov 1.

Department of Emergency Medicine, Icahn School of Medicine at Mount Sinai, New York, NY

Electrical injuries can be caused by exposure to current from low-voltage and high-voltage sources as well as lightning strikes, and the circumstances of the exposure will dictate management strategies. Human tissues have varying resistance characteristics and susceptibility to damage, so injuries may be thermal, electrical, and/or mechanical, potentially causing burns, thrombosis, tetany, falls, and blast injury. This issue reviews the types of trauma seen with electrical injury and how body systems can be affected by occult or delayed effects, and the optimal evidence-based resuscitation and management strategies associated with each.

Modulation of hydroxyl variability by ENSO in the absence of external forcing.

Proc Natl Acad Sci U S A 2018 09 20;115(36):8931-8936. Epub 2018 Aug 20.

Department of Earth and Planetary Sciences, University of California, Berkeley, CA 94720.

The hydroxyl radical (OH) is the primary oxidant in the troposphere, and the impact of its fluctuations on the methane budget has been disputed in recent years, however measurements of OH are insufficient to characterize global interannual fluctuations relevant for methane. Here, we use a 6,000-y control simulation of preindustrial conditions with a chemistry-climate model to quantify the natural variability in OH and internal feedbacks governing that variability. We find that, even in the absence of external forcing, maximum OH changes are 3. Read More

National Space Institute (DTU Space) Technical University of Denmark Lyngby Denmark.

Bursts of X-rays and -rays are observed from lightning and laboratory sparks. They are bremsstrahlung from energetic electrons interacting with neutral air molecules, but it is still unclear how the electrons achieve the required energies. It has been proposed that the enhanced electric field of streamers, found in the corona of leader tips, may account for the acceleration; however, their efficiency is questioned because of the relatively low production rate found in simulations.

Prevalent lightning sferics at 600 megahertz near Jupiter's poles.

Nature 2018 06 6;558(7708):87-90. Epub 2018 Jun 6.

NASA/Goddard Spaceflight Center, Greenbelt, MD, USA.

Lightning has been detected on Jupiter by all visiting spacecraft through night-side optical imaging and whistler (lightning-generated radio waves) signatures. Jovian lightning is thought to be generated in the mixed-phase (liquid-ice) region of convective water clouds through a charge-separation process between condensed liquid water and water-ice particles, similar to that of terrestrial (cloud-to-cloud) lightning. Unlike terrestrial lightning, which emits broadly over the radio spectrum up to gigahertz frequencies, lightning on Jupiter has been detected only at kilohertz frequencies, despite a search for signals in the megahertz range .

Key Laboratory for Organic Electronics and Information Displays and Institute of Advanced Materials (IAM), National Jiangsu Synergetic Innovation Center for Advanced Materials (SICAM), Nanjing University of Posts and Telecommunications, 9 Wenyuan Road, Nanjing, 210023, China.

A novel plasmonic heterodimer nanostructure with a controllable self-assembled hot spot is fabricated by the conjugation of individual Au@Ag core-shell nanocubes (Au@Ag NCs) and varisized gold nanospheres (GNSs) via the biotin-streptavidin interaction from the ensemble to the single-assembly level. Due to their featured configurations, three types of heterogeneous nanostructures referred to as Vertice, Vicinity, and Middle are proposed and a single hot spot forms between the nanocube and nanosphere, which exhibits distinct diversity in surface plasmon resonance effect. Herein, the calculated surface-enhanced Raman scattering enhancement factors of the three types of heterodimers show a narrow distribution and can be tuned in orders of magnitude by controlling the size of GNSs onto individual Au@Ag NCs.

Deep brain stimulation (DBS) is an established treatment option for advanced stages of Parkinson's disease and other movement disorders. It is known that DBS is susceptible to strong electromagnetic fields (EMFs) that can be generated by various electrical devices at work, home, and in medical environments. EMFs can interfere with the proper functioning of implantable pulse generators (IPGs). Read More
