Coded messages in invisible ink sound like something only found in espionage books, but in real life, they can have important security purposes. Yet, they can be cracked if their encryption is predictable. Now, researchers reporting in ACS Applied Materials & Interfaces have printed complexly encoded data with normal ink and a carbon nanoparticle-based invisible ink, requiring both UV light and a computer that has been taught the code to reveal the correct messages.
The distance between the product and the consumer, whether in real life or in ads, can have a profound influence on how consumers evaluate the product and make purchase decisions.
A new machine-learning program accurately identifies COVID-19-related conspiracy theories on social media and models how they evolved over time--a tool that could someday help public health officials combat misinformation online.
The corona pandemic has had a major impact on the Nordic news media. At the same time as advertising revenues have fallen drastically, interest among the audience for professional news coverage has increased, according to a new report from Nordicom at the University of Gothenburg. Several Nordic media companies have also reported record sales of digital subscriptions as a result of the pandemic.
Community newspapers often serve as the public's main source of accurate, local news. They also can be an important way to share the impact of major national events, such as a global pandemic. As the COVID-19 pandemic began spreading throughout the United States, journalism scholars at the University of Missouri and the University of Kansas found that community newspapers across the country began to reevaluate the way they had been doing business for decades.
Misinformation about COVID-19 is spreading from the United States into Canada, undermining efforts to mitigate the pandemic. A study led by McGill University shows that Canadians who use social media are more likely to consume this misinformation, embrace false beliefs about COVID-19, and subsequently spread them.
The public could lose trust in science if scientific and medical researchers choose to bypass the traditional high standards of peer-reviewed medical journals in the rush to get research data released, particularly during crises such as the COVID-19 pandemic.
If you count yourself among those who lose themselves in the lives of fictional characters, scientists now have a better idea of how that happens. Researchers found that the more immersed people tend to get into "becoming" a fictional character, the more they use the same part of the brain to think about the character as they do to think about themselves.
UCLA professor of sociology Gabriel Rossman's study, published in Proceedings of the National Academy of Sciences, uses computer simulations of networks to reveal how the presence of even just a bit of advertising or other mass communication -- "top-down" information that comes from outside a given network -- effectively equalizes the influence of everyone across that network. When advertising exists... "it's not that word-of-mouth doesn't matter -- it's that nobody is particularly important for the process," Rossman said.
A new analysis of education debates on both social media and in traditional media outlets suggests that the education sector is being increasingly influenced by populism and the wider social media 'culture wars'.
