Douglas Wilbur '14, a visiting Ph.D. scholar in the Department of Communication at UTSA, has published a study that shows how researchers can craft message campaigns to protect individuals from adopting extremist views.
According to his research, when people are explicitly told that they are free to accept or reject propagandistic claims, the likelihood of choosing a moderate view increases. This was a result of a survey of attitudes that tested counter-propaganda strategies, which stressed a person's autonomy, and then measured sentiments after exposure.
NEW YORK, NY (April 16, 2021)--SARS-CoV-2, the virus that causes COVID-19, likely does not directly infect the brain but can still inflict significant neurological damage, according to a new study from neuropathologists, neurologists, and neuroradiologists at Columbia University Vagelos College of Physicians and Surgeons.
"It is machination, it is deception," said the Director General of the Berlin Royal Museums in his defence when criticized for buying a fake. Wilhelm Bode did not budge an inch: the sculpture he acquired in 1909 was an as yet unknown production of the great Renaissance master, Leonardo da Vinci. After one hundred years and numerous controversies, a group of scientists led by a CNRS researcher* has just proven him wrong once and for all.
In a new publication from Opto-Electronic Advances; DOI https://doi.org/10.29026/oea.2021.200031, Researchers led by Professor Baohua Jia at Swinburne University of Technology, Victoria, Australia, Professor Cheng-Wei Qiu at National University of Singapore, Singapore and Professor Tian Lan at Beijing Institute of Technology, Beijing, China considered the generation of super-resolved optical needle and multifocal array using graphene oxide metalenses.
If you are exposed to silica (quartz) dust at work - e.g. from working with concrete and granite - you have a greater risk of certain types of rheumatic disease. This is shown by results from Aarhus University and Aarhus University Hospital, which have just been published in the International Journal of Epidemiology.

The leading newspapers in two nuclear waste management forerunner countries, Finland and France, fulfil their "watchdog" roles in highly distinct ways. The Finnish Helsingin Sanomat (HS) tends to reproduce government and industry framings, whereas Le Monde cherishes its role as an independent critic of the powers that be. These differences reflect distinct cultural, political and media traditions in the two countries.
Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy. In a gradual process of elimination, the field of possible explanations has narrowed as new pieces of information are gathered about FRBs - how long they last, the frequencies of the radio waves detected, and so on.

The experimental antiviral drug MK-4482 significantly decreased levels of virus and disease damage in the lungs of hamsters treated for SARS-CoV-2 infection, according to a new study from National Institutes of Health scientists. SARS-CoV-2 is the virus that causes COVID-19. MK-4482, delivered orally, is now in human clinical trials. Remdesivir, an antiviral drug already approved by the U.S. Food and Drug Administration for use against COVID-19, must be provided intravenously, making its use primarily limited to clinical settings.
A survey of star formation activity in the Orion Nebula Cluster found similar mass distributions for newborn stars and dense gas cores, which may evolve into stars. Counterintuitively, this means that the amount of gas a core accretes as it develops, and not the initial mass of the core, is the key factor in deciding the final mass of the produced star.
The nervous system is the internet of the human body and can in the same way transfer signals over long distances very quickly. Some of the most important elements in this signaling are the axons. They are projections of the nerve cells which send signals to other nerve cells or muscles. For instance, axons that jut out from nerve cells in the spinal cord can be over one meter long.
Researchers from the Faculty of Health and Medical Sciences at the University of Copenhagen have now in a new study examined how signal molecules are transported in the axons.
A candidate vaccine that could provide protection against the COVID-19 virus and other coronaviruses has shown promising results in early animal testing.
The candidate coronavirus vaccines, created by Virginia Tech's University Distinguished Professor X.J. Meng and UVA Health's Professor Steven L. Zeichner, prevented pigs from being becoming ill with a pig coronavirus, porcine epidemic diarrhea virus (PEDV).
Angiogenesis is a process of new vessel formation that is activated both in physiological (tissue repair, reproduction, etc.) and pathological (myocardial infarction, diabetic retinopathy, cancer, etc.) conditions. The process is carried out by endothelial cells and includes their proliferation, migration and arrangement in tubes. Angiogenesis regulation is precise and is mainly mediated by pro-angiogenic factors, such as vascular endothelial growth factor (VEGF), which in turn promote different signalling pathways leading to an increase of intracellular Ca2+ concentrations.
Russian scientists have proposed a theory of phase transformation in polymer gels. It explains the mechanisms of the dramatic reduction in volume of zwitterionic hydrogels when they are cooled. The results are published in the journal Chemical Communications (ChemComm).
Prime editing (PE), a "search-and-replace" CRISPR-based genome editing technique, has great potential for gene therapy and agriculture. It can introduce desired base conversions, deletions, insertions, and combination edits into target genomic sites. Prime editors have been successfully applied in animals and plants, but their off-target effects, which can be a major hindrance to real-life application, have not been thoroughly evaluated until now.
It is an old-standing theory in evolutionary ecology: animal species on islands have the tendency to become either giants or dwarfs in comparison to mainland relatives. Since its formulation in the 1960s, however, the 'island rule' has been severely debated by scientists. In a new publication in Nature Ecology and Evolution on April 15, researchers solved this debate by analysing thousands of vertebrate species. They show that the island rule effects are widespread in mammals, birds and reptiles, but less evident in amphibians.
