Moisture is the main environmental factor that triggers the degradation of the masterpiece The Scream (1910?) by Edvard Munch, according to the finding of an international team of scientists led by the CNR (Italy), using a combination of in situ non-invasive spectroscopic methods and synchrotron X-ray techniques.
New research by Rutgers scientists reaffirms that modern sea-level rise is linked to human activities and not to changes in Earth's orbit.
Surprisingly, the Earth had nearly ice-free conditions with carbon dioxide levels not much higher than today and had glacial periods in times previously believed to be ice-free over the last 66 million years, according to a paper published in the journal Science Advances.
(Boston)--Even among individuals free of heart failure and myocardial infarction, there appears to be evidence of an association between calcium buildup in the coronary arteries (atherosclerosis) and changes in the structure and function of the heart.
Coronary artery calcium buildup or atherosclerosis is a strong predictor of future coronary heart disease. To date, the evidence suggests that coronary disease interacts and progresses along with the incipient development of myocardial disease, even in the absence of symptoms.
While many of us use social media to be tickled silly by cat videos or wowed by delectable cakes, others use them to discover new species. Included in the latter group are researchers from the University of Copenhagen's Natural History Museum of Denmark. Indeed, they just found a new type of parasitic fungus via Twitter.
In Germany, growth of COVID-19 cases declined after a series of three social distancing interventions, detectable at a two-week delay following each intervention, but only after the third- a far-reaching contact ban - did cases decline significantly. These results - from a modeling study designed to better estimate the impact of various levels of social distancing on virus spread - indicate that the full extent of social distancing interventions was necessary to stop exponential growth in Germany, the authors say.
Mergers between black holes and neutron stars in dense star clusters are quite unlike those that form in isolated regions where stars are few. Their associated features could be crucial to the study of gravitational waves and their source. Dr Manuel Arca Sedda of the Institute for Astronomical Computing at Heidelberg University came to this conclusion in a study that used computer simulations. The research may offer critical insights into the fusion of two massive stellar objects that astronomers observed in 2019.
The discovery of a huge number of long non-protein coding RNAs, aka lncRNAs, in the mammalian genome was a major surprise of the recent large-scale genomics projects. An international team including a bioinformatician from the Research Center of Biotechnology of the Russian Academy of Sciences, and the Moscow Institute of Physics and Technology has developed a reliable method for assessing the role of such RNAs.
A major global cooling event that occurred 4,200 years ago may have led to the evolution of new rice varieties and the spread of rice into both northern and southern Asia, an international team of researchers has found.
Their study, published in Nature Plants and led by the NYU Center for Genomics and Systems Biology, uses a multidisciplinary approach to reconstruct the history of rice and trace its migration throughout Asia.
Ludwig-Maximilians-Universität (LMU) in Munich researchers have shown that a specific class of immune cells in the blood induced by vaccination is an earlier indicator of vaccine efficacy than conventional tests for neutralizing antibodies.
Early humans lived in South African river valleys with deep, fertile soils filled with grasslands, floodplains, woodlands, and wetlands that abounded with hippos, zebras, antelopes, and many other animals, some extinct for millennia.
In contrast to ice age environments elsewhere on Earth, it was a lush environment with a mild climate that disappeared under rising sea levels around 11,500 years ago.
Scientists from the CNRS and the ENS-PSL in France (1) and Monash University in Australia have shown that the brain suppresses information from the outside world, such as the sound of a conversation, during the sleep phase linked to dreaming. This ability could be one of the protective mechanisms of dreams. The study, carried out in collaboration with the Centre du Sommeil et de la Vigilance, Hôtel-Dieu, AP-HP - Université de Paris, is published in Current Biology on 14 May 2020.
The study now published in Nature Cell Biology reveals more information on the capacity of plants, identified as 'epigenetic memory,' which allows recording important information to, for example, remember prolonged cold in the winter to ensure they flower at the right time during the spring.
As soon as they produce seeds, this information is "erased" from memory so they don't bloom too early the following winter.
CHICAGO (May 15, 2020): When researchers from the University of Colorado Anschutz Medical Campus, Aurora, used a combination of two specific blood-clotting tests, they found critically ill patients infected with Coronavirus Disease 2019 (COVID-19) who were at high risk for developing renal failure, venous blood clots, and other complications associated with blood clots, such as stroke.
Leesburg, VA, May 15, 2020--In an open-access article published ahead-of-print by the American Journal of Roentgenology (AJR), a team of Chinese radiologists discussed modifications to the CT examination process and strict disinfection of examination rooms, while outlining personal protection measures for radiographers during the coronavirus disease (COVID-19) outbreak.
