Scientists at UCL and the IIT -Istituto Italiano di Tecnologia (Italian Institute of Technology) have created a temporary tattoo with light-emitting technology used in TV and smartphone screens, paving the way for a new type of "smart tattoo" with a range of potential uses.
The technology, which uses organic light-emitting diodes (OLEDs), is applied in the same way as water transfer tattoos. That is, the OLEDs are fabricated on to temporary tattoo paper and transferred to a new surface by being pressed on to it and dabbed with water.
The investigation of Electron-Positron-Ion (EPI) plasma?--?a fully ionised gas of electrons and positrons that includes astrophysical plasmas like solar winds?--?has attracted a great deal of attention over the last twenty years. A new study published in EPJ D by Garston Tiofack, Faculty of Sciences, University of Marousa, Cameroon, and colleagues, assesses the dynamics of positron acoustic waves (PAWS) in EPI plasmas whilst under the influence of magnetic fields, or magnetoplasmas.
Whilst a great deal of research has studied the rates of photons escaping from cold atomic gases, these studies have used a scalar description of light leaving some of its properties untested.
Neutron scattering is a technique commonly used in physics and biology to understand the composition of complex multicomponent mixtures and is increasingly being used to study applied materials such as food. A new paper published in EPJ E by Gregory N Smith, Niels Bohr Institute, University of Copenhagen, Denmark, shows an example of neutron scattering in the area of food science. Smith uses neutron scattering to better investigate casein micelles in milk, with the aim of developing an approach for future research.
Both Democrats and Republicans overwhelmingly favor politicians who support generous COVID-19 relief spending, yet remain deeply polarized over the legitimacy of the 2020 presidential election results and former President Donald Trump's second impeachment. Meanwhile, political experts find that the former president's actions and those taken by congressional supporters in the aftermath of the election represent serious departures from American democratic norms.
A Swansea University scientist's research into the geometrical characteristics of a physical theories is highlighted in a new paper.
Physicist Dr Farid Shahandeh said: "Imagine a physical theory whose explanation for the trajectory of an apple falling from a tree differs for Gala and Pink Lady. We know that the apple's variety has nothing to do with how it falls. A theory like this is overcomplicated.
"Any seemingly unnecessary and nonsensical parameter like this adds context to a theory's description of a physical phenomenon.
HOUSTON - (Feb. 26, 2021) - In a twist befitting the strange nature of quantum mechanics, physicists have discovered the Hall effect -- a characteristic change in the way electricity is conducted in the presence of a magnetic field -- in a nonmagnetic quantum material to which no magnetic field was applied.
HOUSTON - (Feb. 26, 2021) - Save your silver! It's better used for jewelry than as a catalyst for drugs.
Rice University scientists have developed a greatly simplified method to make fluoroketones, precursors for drug design and manufacture that typically require a silver catalyst.
Rice chemist Julian West and graduate students Yen-Chu Lu and Helen Jordan introduced a process for the rapid and scalable synthesis of fluoroketones that have until now been challenging and expensive to make.
Ultra-fast, cheap LAMP-based COVID tests could be performed by non-experts at work and in public spaces, giving results in under an hour
With the hope of contributing to the fight against cancer, researchers in Sweden have published a new molecular mapping of proteins that regulate the cell division process - identifying 300 such proteins.
The release of the data, which was published today in the scientific journal, Nature, is significant because it helps bring medical research closer to the point of being able to target specific proteins to treat cancer.
What The Study Did: National COVID-19 registry data are used in this study to describe the epidemiology, clinical characteristics, complications, and hospital and postdischarge outcomes of pediatric patients with multisystem inflammatory syndrome in children (MIS-C) and to compare each in patients with severe COVID-19.
Authors: Adrienne G. Randolph, M.D., of Boston Children's Hospital, is the corresponding author.
Small changes to people's writing style can reveal which social group they "belong to" at a given moment say psychologists.
Groups are central to human identity, and most people are part of multiple groups based on shared interests or characteristics - ranging from local clubs to national identity.
When one of these group memberships becomes relevant in a particular situation, behaviour tends to follow the norms of this group so that people behave "appropriately".
MEMPHIS, TN, FEBRUARY 24, 2021:- Early diagnosis of Alzheimer's disease has been shown to reduce cost and improve patient outcomes, but current diagnostic approaches can be invasive and costly. A recent study, published in the Journal of Alzheimer's Disease, has found a novel way to identify a high potential for developing Alzheimer's disease before symptoms occur. Ray Romano, Ph.D., RN, completed the research as part of his Ph.D.
Plants and animals can rapidly respond to changes in their environment, such as a Venus flytrap snapping shut when a fly touches it. However, replicating similar actions in soft robots requires complex mechanics and sensors. Now, researchers reporting in ACS Applied Materials & Interfaces have printed liquid metal circuits onto a single piece of soft polymer, creating an intelligent material that curls under pressure or mechanical strain. Watch a video of the smart material here.
Improving road safety in cities could result in a lower rate of violent crime, according to research from UCL.
Experts analysing crime and car accident data in Mexico City found a surprisingly high level of synchronicity between the two on a weekly cycle, suggesting that applying more resources to prevent road accidents would improve crime rates by enabling more efficient policing.
