An NTU Singapore study has found that one in three Singaporeans who said they were aware of deepfakes believe they have circulated deepfake content on social media which they later found out was a hoax. When compared to a similar demographic in the United States, the study found that those in the US were more aware of deepfakes. More reported sharing content that they later learnt was a deepfake in the US than in Singapore.
Forensic science experts at Flinders University are refining an innovative counter-terrorism technique that checks for environmental DNA in the dust on clothing, baggage, shoes or even a passport. "This microscopic environmental trace evidence, based on soil geochemical, bacterial and fungal analysis would complement and enhance current forensic intelligence tools," lead researcher Dr Jennifer Young says in new research in Forensic Science International: Genetics.
Machine learning can be used to fill a significant gap in Canadian public health data related to ethnicity and Aboriginal status, according to research published in PLOS ONE by a University of Alberta research epidemiologist.
Scientists at the Complexity Science Hub Vienna show that the accelerating fragmentation of society - often referred to as filter bubbles -- is a direct consequence of the growing number of social contacts. According to their new theory of social fragmentation, societies can only be either cohesive or fragmented, with abrupt changes from one state to the other at certain tipping points. Filter bubble societies are a risk for democracies.
A social scientist at Brown is calling on research institutions, leading scientific journals and national professional associations to establish new ethical standards that protect human subjects from emotional, financial and political manipulation.
A new analysis of the United States government's response to COVID-19 highlights myriad problems with an approach that relied, in large part, on international supply chains and the Strategic National Stockpile. A panel of academic and military experts is instead calling for a more dynamic, flexible approach to emergency preparedness at the national level.
In a new report, a team of Yale scientists has developed a way to protect people's private genetic information while preserving the benefits of a free exchange of functional genomics data between researchers.
The study merges demographic data, epidemiological estimates and anonymous cellphone location information, and appears to confirm that most COVID-19 transmissions occur at "superspreader" sites like full-service restaurants, fitness centers and cafes, where people remain in close quarters for extended periods. The model could help officials minimize the contagion as they reopen businesses by revealing the tradeoffs between infections and sales if establishments open at 20 percent or 50 percent or full capacity.
Dr. Atanu Lahiri and Dr. Zhiqiang Zheng studied the relationship between online reviews of physicians and their patients' actual clinical outcomes. They wanted to know how much consumers can rely on the reviews, specifically in regard to chronic-disease care.
Researchers compared the effect and reach of studies about therapies for COVID-19 posted on the medRxiv preprint server, subsequent publications in medical journals of some of these studies, and journal articles that were not posted on either medRxiv or another preprint server.
