Increased methane emissions from deep osmotic and buoyant convection beneath submarine seeps as climate warms.
High speeds have been measured at seep and mud-volcano sites expelling methane-rich fluids from the seabed. Thermal or solute-driven convection alone cannot explain such high velocities in low-permeability sediments. Here we...
On the differing growth mechanisms of black-smoker and Lost City-type hydrothermal vents.
Black smokers and Lost City-type springs are varieties of hydrothermal vents on the ocean floors that emit hot, acidic water and cool, alkaline water, respectively. While both produce precipitation structures as the issuing...
Exploding Chemical Gardens
Yang Ding, Carlos M Gutiérrez-Ariza, C Ignacio Sainz-Díaz, Julyan HE Cartwright, Silvana SS Cardoso
May 03, 2019
Chemical gardens and clock reactions are two of the best-known demonstration reactions in chemistry. Until now these have been separate categories. We have discovered that a chemical garden confined to two dimensions is a clock...
How the City of London lost at Brexit
HE Thompson
Aug 23, 2017
The nature of the City of London as an offshore financial centre has long made London dependent on the British state providing protection from external political regulation, even as London’s foreign currency business separated...
Diagnostics of Non-Maxwellian Electron Distributions in Solar Active Regions from Fe xii Lines Observed by the Hinode Extreme Ultraviolet Imaging Spectrometer and Interface Region Imaging Spectrograph
Abstract
We present joint Hinode Extreme Ultraviolet Imaging Spectrometer (EIS) and Interface Region Imaging Spectrograph (IRIS) observations of Fe xii lines in...
Electronic stopping power in gold
The electronic stopping power of H and He moving through gold is obtained to high accuracy using time-evolving density-functional theory, thereby bringing usual first principles accuracies into this kind of strongly coupled...
Route to high-energy density polymeric nitrogen t-N via He-N compounds.
Yinwei Li, Xiaolei Feng, Hanyu Liu, Jian Hao, Simon AT Redfern, Weiwei Lei, Dan Liu, Yanming Ma
Mar 16, 2018
Polymeric nitrogen, stabilized by compressing pure molecular nitrogen, has yet to be recovered to ambient conditions, precluding its application as a high-energy density material. Here we suggest a route for synthesis of a...
R-matrix Electron-impact Excitation Data for the H- and He-like Ions with Z = 6−30
Abstract
Plasma models built on extensive atomic data are essential to interpreting observed cosmic spectra. H-like Lyman series and He-like triplets observable in the X-ray band...
Altering the availability of healthier vs. less healthy items in UK hospital vending machines
BACKGROUND:Altering the availability of healthier or less-healthy products may increase healthier purchases, but evidence is currently limited. The current study aimed to investigate the impact of altering the...
Stokes drift through corals
We investigate the all-penetrating drift velocities, due to surface wave
motion in an effectively inviscid fluid that overlies a saturated porous bed of
finite depth. Previous work in this area either neglects the large-scale...

Abstract: Background: Altering the availability of healthier or less-healthy products may increase healthier purchases, but evidence is currently limited. The current study aimed to investigate the impact of altering the...
'Joining a group was inspiring'
BACKGROUND: Yoga is becoming an increasingly popular holistic approach in the West to manage long-term health conditions. This study presents the evaluation of a pilot yoga intervention, Yoga4Health, that was developed for the...
Photochromic Fluorescent Probe Strategy for the Super-resolution Imaging of Biologically Important Biomarkers
Xianzhi Chai, Hai Hao Han, Adam C. Sedgwick, Na Li, Yi Zang, Tony D. James, Junji Zhang, Xi Le Hu, Yang Yu, Yao Li, Yan Wang, Jia Li, Xiao Peng He, He Tian
Oct 21, 2020
Here, we report a β-galactosidase (β-Gal)-responsive photochromic fluorescent probe, NpG, that was designed to prebind to human serum albumin (HSA) to form the probe/protein hybrid, NpG@HSA. The formation of NpG@HSA led to an...
He Ala Kuikui Lima Kānaka
This article focuses on decolonizing, or specifically Indigenizing, a school of social work that has a stated focus on Native Hawaiians, other Pacific Islanders, and Asian populations in the Pacific region. Armed with Kanaka...

Artists before Columbus
This study represents the first positive identification of plant gum binding media in pre-Columbian art, and the first dates from indigenous cave art in the Caribbean. Mona Island reveals an extensive and well-preserved...
Impact of reducing portion sizes in worksite cafeterias
Gareth J Hollands, Emma Cartwright, Mark Pilling, Rachel Pechey, Milica Vasiljevic, Susan A Jebb, Theresa M Marteau
Nov 12, 2018
BACKGROUND: Reducing the portion sizes of foods available in restaurants and cafeterias is one promising approach to reducing energy intake, but there is little evidence of its impact from randomised studies in field settings....
