(Press-News.org) Identifying whether online information is faulty or ungrounded is important to ensure information integrity and a well-informed public. This was especially challenging during the COVID-19 pandemic when misinformation spread like wildfire across the Internet. A new project led by Dong Wang, associate professor in the School of Information Sciences at the University of Illinois Urbana-Champaign, will integrate diverse human and machine intelligence to examine multimodal data (e.g., text and image) that was produced during the pandemic. His project, "Crowd-Assisted Human-AI Teaming with Explanations," has been awarded a three-year, $599,999 grant from the National Science Foundation (NSF).
According to Wang, the new project will develop a crowd worker-based interactive artificial intelligence (AI) system that explores the collective strengths of the professional knowledge of domain expert crowd workers, the general logical reasoning ability of non-expert crowd workers, and the effective information retrieval capability of AI models. The researchers will recruit experts in the field, such as healthcare providers, and freelance workers, or average people, from crowdsourcing platforms like Amazon MTurk or Prolific. These crowd workers will perform tasks to help train the AI models, making the system more robust.
"While significant efforts in artificial intelligence and machine learning have addressed information integrity in this type of multimodal setting, many solutions cannot be directly applied due to lack of domain specific knowledge and the expertise needed to provide meaningful, convincing explanations," Wang said.
While the focus of this project is COVID-19, the framework and models that are developed will be able to address information integrity with explanations in other domains, such as healthcare, disaster response, and public safety.
Wang's research interests lie in the areas of human-centered AI, social sensing and intelligence, big data analytics, misinformation detection, and human cyber-physical systems. He holds a PhD in computer science from the University of Illinois Urbana-Champaign.

Plastic pollution sounds just like food to deep-diving whales
2024-10-16
BEAUFORT, N.C. -- To whales that hunt with soundwaves in the lightless depths of the ocean, a torn plastic party balloon and a delicious squid seem to be remarkably similar, according to a new study that put some plastic beach trash through underwater acoustic testing.
"These acoustic signatures are similar, and this might be a reason that these animals are driven to consume plastic instead of, or in addition to, their prey," said Duke University graduate student Greg Merrill, who led the research.
"One hundred percent of plastic marine debris ...
Innovating in the corners where atoms meet
2024-10-16
How can we engineer materials that are stronger and lighter? What about new materials for extreme conditions such as in jet engines and spacecrafts?
The answer, says Fadi Abdeljawad, an associate professor of materials science and engineering in Lehigh University's P.C. Rossin College of Engineering and Applied Science, might be hidden in the infinitesimally tiny regions, or boundaries, where atoms in crystals come together.
Along with his collaborators at the U.S. Department of Energy's Center for Integrated Nanotechnologies (CINT), Abdeljawad is uncovering how those ...
Study offers better insights into quality of life for adults with congenital heart disease
2024-10-16
Washington, D.C. (October 16, 2024) – For the first time, adults living with congenital heart disease (CHD) now have valuable insights into their long-term quality of life through data from the Congenital Heart Initiative (CHI). CHI is the nation’s first and largest patient-focused registry for adults with CHD and released its first study involving over 4,500 participants from all 50 states.
This research, published today in JAMA Network Open, marks a significant step forward in making better information available for the ...
Researchers offer alternative to hydroxyurea in study of DNA replication process
2024-10-16
Researchers at Colorado State University have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than current drug methods used to understand cell cycle arrest – a fundamental mechanism that is key to treating cancers and genetic issues.
The findings were published in the Proceedings of the National Academy of Sciences and were led at CSU by Assistant Professor Grant Schauer in the Department of Biochemistry and Molecular Biology. The work focuses on hydroxyurea, a chemotherapy drug used ...
New diamond bonding technique a breakthrough for quantum devices
2024-10-16
Synthetic diamond is durable, inert, rigid, thermally conductive and chemically well-behaved—an elite material for both quantum and conventional electronics. But there’s one problem. Diamond only likes diamond.
It’s homoepitaxial, meaning it only grows on other diamonds, and integrating diamond into quantum or conventional computers, quantum sensors, cellphones, or other devices would mean sacrificing the diamond’s full potential or using large, expensive chunks of the precious material.
“Diamond stands alone in terms of its material properties, both for electronics—with its wide band gap, ...
Clean air and climate policies provide health benefits in New York City
2024-10-16
A new study analyzes the links between the enactment of major air pollution and climate policies in New York City and significant improvement in air quality during the period 1998-2021. It finds a cumulative beneficial effect of these policies both city-wide and among residents residing in communities that have been disproportionately affected by air pollution.
The study by environmental health scientists at Columbia University Mailman School of Public Health is published in the peer-reviewed journal Frontiers in Public Health.
“Because of the known significant associations between the pollutants studied and multiple adverse health effects, there are important implications for health ...
Folic acid may mitigate link between lead exposure during pregnancy and autistic behaviours in children
2024-10-16
New research gives another reason to take folic acid supplements while pregnant.
A new study by Simon Fraser University researchers has found that folate may weaken the link between blood-lead levels in pregnant women and autistic-like behaviours in their children.
Researchers from SFU’s Faculty of Health Sciences, led by PhD candidate Joshua Alampi, published the study in the journal Environmental Health Perspectives.
“Folic acid supplementation during pregnancy has numerous benefits to child health, especially brain development,” ...

STEP Demo pilot plant achieves full operational conditions for Phase 1 of testing
2024-10-16
SAN ANTONIO — October 16, 2024 —The Supercritical Transformational Electric Power (STEP) Demo pilot plant, a $169 million, 10-megawatt supercritical carbon dioxide (sCO2) test facility at Southwest Research Institute (SwRI) in San Antonio, has completed its first phase of testing, having achieved its full operational speed of 27,000 rpm and operating at a target turbine inlet temperature of 500 degrees Celsius. As STEP achieved this milestone, it was synchronized with the electrical grid, generating approximately four megawatts of net power.
“Achieving full operating conditions while connected to the grid is a major advancement ...
Women more likely than men to die after heart surgery complications
2024-10-16
Despite having no greater chance of developing problems after high risk cardiovascular surgery, women are more likely than men to die from postoperative complications, a University of Michigan-led study suggests.
A patient dying of complications after surgery is often referred to as a “failure to rescue”.
Investigators assessed more than 850,000 cases of Medicare beneficiaries who had high risk heart surgery — including heart bypass, aortic aneurysm repair, and mitral and aortic valve repair — ...
