Quantum Hall effect (QHE) plays an important role in materials science and precision measurement. Due to the dissipationless edge states, QHE exhibits exotic transport properties with quantized Hall resistance of h/νe2 and vanishing longitudinal resistance. Here, h is Planck's constant, ν is Landau filling factor and e is electron charge. QHE usually originates from the formation of remarkable energy gap and the broken time-reversal-symmetry, which requires materials with high mobility, high magnetic field and ultralow temperature.
Marine life off the West Coast, from Mexico up through Canada, inhabit the California Current. The cool, nutrient-rich water supports life from invisible phytoplankton to the economically important salmon, rockfish and Dungeness crab to the majestic orcas.
The largest collection of footprints from the human fossil record in Africa is described in Scientific Reports this week. The findings, which further our understanding of human life during the Late Pleistocene period (126,000 to 11,700 years ago), suggest a division of labour in ancient human communities.
An off-label experiment in mice using disulfiram, which has been used to treat alcohol use disorder for more than 50 years, consistently normalized body weight and reversed metabolic damage in obese middle-aged mice of both sexes. The international study was led by researchers at the National Institute on Aging (NIA), part of the National Institutes of Health . The results were published online in the journal Cell Metabolism on May 14.
A group of patients with diabetes were surveyed on their understanding of the consent process to have their medical data shared with digital platforms offering innovations to the management of their condition.
The current ability to share patient data between different practices, who each specialise in different aspects of the patients care, is a long process
However, the Dovetail digital consent application uses a mobile application and blockchain infrastructure to offer an IT technology, which facilitate sharing patient data and offer them the right to revoke consent
MINNEAPOLIS, MN- May 14, 2020 - In a vertical climb to avoid collision with a towering mountain, a plane ejects cargo to gain altitude. Investigators at the University of Minnesota showed that cancer cells perform similar feats in escaping the killing effects of radiation. Their work was published in the May issue of the journal, EBiomedicine.
BIRMINGHAM, Ala. - Many heart diseases are linked to oxidative stress, an overabundance of reactive oxygen species. The body reacts to reduce oxidative stress -- where the redox teeter-totter has gone too far up -- through production of endogenous antioxidants that reduce the reactive oxygen species. This balancing act is called redox homeostasis.
It has been nearly two decades since the American College of Medical Genetics and Genomics (ACMG), together with the American College of Obstetricians and Gynecologists, made the landmark recommendation that cystic fibrosis (CF) become the first target of pan-ethnic universal carrier screening, with ACMG identifying a core panel of 23 pathogenic variants to be tested. Now, with the widespread availability and decreased cost of next-generation sequencing, it is possible to more easily interrogate all regions of the CFTR gene and correlate variants with phenotypes.
Light detection and ranging (LiDAR) comprised an array of techniques using laser light to measure distances by multiplying the time delay between transmitted and received optical signals with the speed of light. Modern 3D LiDAR sensors combine high lateral/vertical and radial resolution, and are key components in the ongoing revolution of level 4 and 5 self-driving cars.
Due to the improvement and increased use of geochemical fingerprinting techniques during the last 25 years, the archaeological compositional data of stone tools has grown exponentially. The Pofatu Database is a large-scale collaborative project that enables curation and data sharing. The database also provides instrumental details, analytical procedures and reference standards used for calibration purposes or quality control. Thus, Pofatu ensures reproducibility and comparability between provenance studies.
New images reveal the earliest impairments to nonhuman primate fetal brain development due to alcohol ingested by the mother, in a study led by scientists at Oregon Health & Science University involving rhesus macaques.
Magnetic resonance imaging showed impairments to brain growth during the third trimester of pregnancy, even though the fetus was exposed to alcohol only during the first trimester.
An imbalance of unstable molecular species called 'free radicals' will change the colour of cells - and a new imaging technique could one day allow scientists to detect and decode this colour without needing to take samples from the body, a new study by UNSW Sydney researchers has found.
The paper was published online yesterday in Redox Biology.
Social and community disruptions caused by the COVID-19 restrictions could have a lasting effect on child wellbeing, Flinders University researchers warn.
While health, safety and education responses are the focus of restrictions, the needs of childhood independence, self-determination and play are less acknowledged, Flinders University experts explain in a new publication.
PHOENIX (May 12, 2020) - Children and young adult burn survivors are more troubled by staring, bullying, and uncomfortable questions than the actual physical discomfort and memories of their accidents, according to research that was selected to be presented at the American Burn Association's Annual Meeting and published in the Journal of Burn Care & Research. While treatment is typically focused primarily on acute care for physical wounds, the surveys suggest that survivors are left with few tools to handle social anxieties and traumatizing memories.
Earth may have been far more oxygen-rich early in its history than previously thought, setting the stage for the evolution of complex life, according to new research by scientists at the University of Alberta and the University of Tartu in Estonia. The study provides evidence for elevated oxygen levels 2 billion years ago and flies in the face of previously accepted models.
