UrduResearchers at the University of Minnesota Twin Cities College of Science and Engineering have developed a new technique that reconstructs two dimensional (2D) radio images–visual representations created from radio waves–into three dimensional (3D) “Pseudo3D cubes” to help better understand objects in the Universe.

Mental health and self-care during election season: MSU experts can comment
MSU experts can comment on the role emotions play during election season and how to take care of yourself when you’re feeling overwhelmed by the news.
On the antipodes of love and hate: The conception and measurement of brand polarization
Abstract Brand polarization represents a somewhat unorthodox approach to brand management. Rather than foster support and minimise opposition towards a brand, polarization maintains strong emotions at both ends of the spectrum, concurrently attending to the antipodes of brand love and…
Claiming market ownership: Territorial activism in stigmatized markets
Abstract Brands that seek to serve stigmatized markets are frequently targeted with activism by stigmatizers who hold discrediting beliefs about the products, practices and/or people associated with such markets. Drawing on an inductive analysis of a large set of qualitative…
K-space translation strategy lets metasurfaces project multiple images without crosstalk
Researchers have developed a new type of planar-glass-waveguide-based metasurface holograms that feature multiple crosstalk-free display channels by precisely manipulating guided incident light.
New discoveries about the nature of light could improve methods for heating fusion plasma
Scientists have made discoveries about light particles known as photons that could aid the quest for fusion energy.
Getting out of the political echo chamber
Civilized political debates may seem increasingly out of reach as democracies across the world face rising polarization, but people still want to discuss issues with people they disagree with – especially those who present themselves as balanced and willing to seek solutions that work for everyone or open to learning new information, according to two studies published by the American Psychological Association.
Rensselaer Researcher Finds That Users Seek Out Echo Chambers on Social Media
We all know that communication encompasses so much more than words. Facial expressions, intonations, hand gestures, and more contribute to our expressiveness. However, in social media, these intricacies are lost.
MSU research suggests darker side of being politically confident
New research from Michigan State University suggests that those who feel self-confident about their political abilities are more likely to discriminate against those who hold opposing political views. And those who are more skeptical of their political abilities are more likely to treat other people fairly when they disagree politically.
On-chip Infrared Circular Polarization Detector with Ultrahigh Discrimination
Filterless light-ellipticity-sensitive optoelectronic response generally has low discrimination, thus severely hindering the development of monolithic polarization detectors.
Fake and Extremely Biased Twitter Content Decreased Between 2016-2020, But Top Influencers Were More Polarized
“One side can start the polarization and keep it going forever, but it takes two sides to stop it. That’s why it easily arises, but it’s so difficult to end,” Boleslaw Szymanski said. Szymanski is the Claire & Roland Schmitt Distinguished Professor of Computer Science and director of the Network Science and Technology Center at Rensselaer Polytechnic Institute.
American University Experts Share Insights on 2nd Anniversary of January 6th Insurrection
What: As we reach the 2nd anniversary of the January 6th insurrection, American University has various scholars who are experts in extremism, far-right ideologies, white supremacy, militias and organized political violence. Below please find their insights on last year and…
Back to Antarctica with SPIDER
In the next few weeks, a team led by researchers at the University of Illinois at Urbana-Champaign will fly an instrument called SPIDER. They are looking for a pattern, or polarization, in the earliest light we can measure.
Rensselaer Researcher To Follow the Trail of Misinformation
On 9/11, lawmakers from both parties unified in their response. Just over 20 years later, Congress is distinctly partisan, clashing on everything from the January 6 insurrection to COVID to climate change. Why? Many blame widespread and widely believed misinformation and disinformation. Rensselaer Polytechnic Institute’s Boleslaw Szymanski, Claire and Roland Schmitt Distinguished Professor of Computer Science, is part of an interdisciplinary team of researchers examining the flow of (mis)information in social media.
Light Polarization Creates Art, Explains Mathematical Concepts
In the American Journal of Physics, Aaron Slepkov from Trent University explores the physics of how polarization-filtered colors emerge, how they can be controlled, and why subtle changes in viewing angle, sample orientation, and the order of layers of films between polarizers can have dramatic effects on the observed colors. The research emphasizes visual examples of concepts related to birefringence, such as addition, subtraction, and order-of-operations.
Mentioning ‘white privilege’ increases online polarization
If there’s an online discussion about race, using the term “white privilege” can create a polarized situation, say University of Michigan researchers.
In a Contentious Era, How Do Friends with Different Values Stick Together? Faculty and Student Research Sheds Light
Americans are perhaps more polarized today than at any time since the Civil War. This idea has become ingrained in contemporary American discourse, popping up with increasing frequency in media coverage, in public opinion studies, and in research about how social media and its “filter bubbles” are driving polarization.
Network scientist Boleslaw Szymanski @RPI offers key insights into polarization, disinformation, and minority power.
People tend to think of the arena of politics as being driven by human decision and emotions, and therefore unpredictable. But network scientists like Boleslaw Szymanski, a computer science professor at Rensselaer Polytechnic Institute, have found that the country’s political…
If COVID-19 can’t foster political unity, what can?
Bitter fighting continues in the aftermath of the 2020 presidential election, even as President-elect Joe Biden urged unity in his victory speech Saturday night. Michael Macy, professor of sociology and information science at Cornell University and director of the Social…
COVID Opens a Partisan Gap on Voting by Mail
Study by UC’s New Electorate Project documents a growing divide on preferences for absentee ballots. Before the pandemic, there wasn’t any difference in the rates at which Democratic and Republican voters actually cast their ballots by mail or in-person. That may change now.
New Algorithms Could Reduce Polarization Driven By Information Overload
As the volume of available information expands, the fraction a person is able to absorb shrinks. To break this cycle, computer scientists say we need new algorithms that prioritize a broader view over fulfilling consumer biases.
Gap between rich, poor neighborhoods growing in some cities
New research provides insight into how housing prices and neighborhood values have become polarized in some urban areas, with the rich getting richer and the poor becoming poorer.
Simulations Show Extreme Opinions Can Lead to Polarized Groups
In this week’s Chaos, researchers use a theoretical model to examine what effect extreme views have on making the entire system more polarized. The group’s network-based model extends a popular approach for studying opinion dynamics, called the Cobb model, and is based on the hypothesis that those with opinions farther from the middle of a political spectrum are also less influenced by others, a trait known to social scientists as “rigidity of the extreme.”
Fake Russian Twitter accounts politicized discourse about vaccines
Activity from phony Twitter accounts established by the Russian Internet Research Agency between 2015 and 2017 may have contributed to politicizing Americans’ position on the nature and efficacy of vaccines, a health care topic which has not historically fallen along party lines, according to new research published in the American Journal of Public Health.
UAH has significant role in LEAP, a mission selected for NASA flight review
In collaboration with Marshall Space Flight Center (MSFC), the Center for Space Plasma and Aeronomic Research (CSPAR) at The University of Alabama in Huntsville (UAH) has a significant role in LEAP – the LargE Area burst Polarimeter – a mission that is one of four proposals approved by NASA for further review.
