MADISON -Using the Wisconsin H-Alpha Mapper telescope, astronomers have for the first time measured the Fermi Bubbles in the visible light spectrum. The Fermi Bubbles are two enormous outflows of high-energy gas that emanate from the Milky Way and the finding refines our understanding of the properties of these mysterious blobs.
Canadian scientists have achieved a first in the study of telomerase, an essential enzyme implicated in aging and cancer.
In today's edition of the prestigious journal Molecular Cell, scientists from Université de Montréal used advanced microscopy techniques to see single molecules of telomerase in living cells.
What The Study Did: Epidemiology, clinical and laboratory features of 50 children hospitalized with COVID-19 in New York are examined in this case series.
Authors: Philip Zachariah, M.D., M.Sc., of Columbia University Irving Medical Center in New York, is the corresponding author.

A cautious approach to easing lockdown restrictions that reduces the risk of later lockdowns may be better for the global supply chain in the long run, according to a new modelling study led by UCL and Tsinghua University.
The paper, published today in Nature Human Behaviour, is the first peer-reviewed study to comprehensively assess potential global supply chain effects of Covid-19 lockdowns, modelling the impact of lockdowns on 140 countries, including countries not directly affected by Covid-19.
A joint team, while exploring phase diagrams in dense H2-HD-D2 mixtures, has reported a new discovery in which they found counterintuitive effects of isotopic doping on the phase diagram of H2-HD-D2 molecular alloy.
This work was conducted by a research team at the Institute of Solid State Physics, Hefei Institutes of Physical Science collaborating with researchers from the Center for High Pressure Science & Technology Advanced Research and University of Edinburgh. It was published in PNAS on 2 June, 2020.
A new mobile app can help clinicians determine which patients with the novel coronavirus (COVID-19) are likely to have severe cases. Created by researchers at NYU College of Dentistry, the app uses artificial intelligence (AI) to assess risk factors and key biomarkers from blood tests, producing a COVID-19 "severity score."
Current diagnostic tests for COVID-19 detect viral RNA to determine whether someone does or does not have the virus--but they do not provide clues as to how sick a COVID-positive patient may become.
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.
