An inflammatory syndrome in children and adolescents, believed to be linked to covid-19, seems to be more common among children of African ancestry, finds a small study from a hospital in Paris, published by The BMJ today.
The syndrome has been compared with Kawasaki disease, a rare condition which mainly affects children under five. Experts have said that it may be an "antibody mediated or delayed response" to covid-19 that happens several weeks after infection.
Cases have also been seen in Italy, the UK and the US.
We can all picture that incredible image of a black hole that travelled around the world about a year ago. Yet, according to new research by SISSA, ICTP and INFN, black holes could be like a hologram, where all the information is amassed in a two-dimensional surface able to reproduce a three-dimensional image. In this way, these cosmic bodies, as affirmed by quantum theories, could be incredibly complex and concentrate an enormous amount of information inside themselves, as the largest hard disk that exists in nature, in two dimensions.
Scientists have long tried to experimentally demonstrate a certain symmetry property of the weak interaction - parity violation - in molecules. So far, this has not been possible. A new interdisciplinary effort led by a research group at the at the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) has now shown a realistic path to demonstrating this phenomenon. The approach includes aspects of nuclear, elementary particle, atomic and molecular physics as well as nuclear magnetic resonance (NMR).
Scientists at Johannes Gutenberg University Mainz (JGU) in Germany have developed a new sustainable method of extracting the flavoring agent vanillin from lignin, a component of wood. Large quantities of waste lignin accumulate during the production of pulp, an important raw material for making paper. The process the researchers describe in their article in ACS Sustainable Chemistry & Engineering involves dissolving the lignin in caustic soda and heating this mixture to 160 degrees Celsius in a simple electrolysis cell with nickel electrodes to which a current is applied.
Gesture is an integral part of language development. Recent studies carried out by the same authors in collaboration with other members of the Prosodic Studies Group (GrEP) coordinated by Pilar Prieto, ICREA research professor Department of Translation and Language Sciences at UPF, have shown that when the speaker accompanies oral communication with rhythmic gesture, preschool children are observed to better understand the message and improve their oral skills.
The use of antiepileptic drugs is associated with a higher risk of death among persons with Alzheimer's disease, according to a new study from the University of Eastern Finland. The results were published in Neurology. The mortality risk increased considerably during the first three months of treatment with antiepileptic drugs, and was higher among users of older antiepileptic drugs in comparison to users of newer antiepileptics. The risk of death remained elevated after exclusion of people with epilepsy in the sensitivity analyses.
Scientists have long debated which genetic information carrier - DNA or RNA - started life on Earth, but a new study suggests life could have begun with a bit of both. The research, led by scientists from the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB), in Cambridge, shows for the first time how some of the building blocks of both DNA and RNA could have spontaneously formed and co-existed in the 'primordial soup' on Earth.
The COVID-19 pandemic has rapidly and dramatically changed how people interact, moving work and social communication online. Use of the internet to stay connected, socialise, shop and conduct business has expanded since the implementation of measures to curtail the spread of COVID-19.
Some people are more sensitive than others - and around half of these differences can be attributed to our genes, new research has found.
The study, led by Queen Mary University of London, compared pairs of identical and non-identical 17-year-old twins to see how strongly they were affected by positive or negative experiences - their 'sensitivity' level. The aim was to tease out how much of the differences in sensitivity could be explained by either genetic or environmental factors during development: nature or nurture.
A wearable biosensor may help monitor stress experienced by healthcare professionals, according to a study published in Physiological Reports.
A study published in the Journal of the American Geriatrics Society examined five personality traits--neuroticism, extraversion, conscientiousness, agreeableness, and openness--and their links to pre-dementia conditions called motoric cognitive risk (MCR) and mild cognitive impairment (MCI) syndromes.
Among 524 adults aged 65 years and older who were followed for a median of 3 years, 38 participants developed MCR and 69 developed MCI (some with memory loss, or amnestic MCI).
Tokyo, Japan - Glass is such a common, everyday material that you probably don't think about it much. It may surprise you to learn that researchers today still don't understand how glass forms. Figuring this out is important for glass industries and many other surprising applications of glasses.
WASHINGTON (June 3, 2020) - The vast majority of U.S. adults (80%) say they will be more mindful about practicing self-care regularly once the pandemic is over, according to a new survey conducted by The Harris Poll on behalf of Samueli Integrative Health Programs. Nearly half of Americans (46%) also report that they are struggling to find ways to maintain their whole health (i.e., physical, mental, and spiritual health) during the pandemic.
Stand outside and look underneath your feet. There, perhaps under some grass, is the soil. On a dry day, all the spaces in the soil are filled with air. And some distance further down, those spaces are entirely water. So, what's in between?
That's the capillary fringe. And it might just be the most important -- and mysterious -- thing you've never heard of.
More than 110 million years ago, a lumbering 1,300-kilogram, armour-plated dinosaur ate its last meal, died, and was washed out to sea in what is now northern Alberta. This ancient beast then sank onto its thorny back, churning up mud in the seabed that entombed it--until its fossilized body was discovered in a mine near Fort McMurray in 2011.
