The emergence and perils of polarization
We can't understand polarization unless we analyze it as a complex system, argue SFI External Professor Scott Page (University of Michigan) and co-author Delia Baldassarri in a commentary for a special feature on the dynamics of political polarizatio.....»»
A new route for universal polarization transformations of spatially varying polarization fields
Polarization describes the orientation of oscillations in a light wave, and it plays an essential role in various optical applications—from enhancing visibility in sunglasses and camera lenses to facilitating advanced optical communication and imag.....»»
Team develops way to integrate electro-optic modulator device on end faces of a single-mode optical fiber jumper
Electro-optic modulators (EOMs) are cardinal elements in the optical communication networks that control the amplitude, phase and polarization of a light via external electric signals. Aiming to realize ultracompact and high-performance EOMs, most in.....»»
How to depolarize political toxicity on social media
While social media is often blamed for exacerbating incivility and partisan polarization, research led by Duke University scholars found that anonymous online conversations using a mobile chat platform they developed can reduce political polarization.....»»
Political polarization toned down through anonymous online chats
Republicans seem to depolarize more than Democrats. Enlarge (credit: Carol Yepes/Getty) Political polarization in the US has become a major issue, as Republicans and Democrats increasingly inhabit separate realities on t.....»»
X roundup: Trump disclosures serve as warning; ads next to alt-right posts; scientists leave

Arrays of quantum rods could enhance TVs or virtual reality devices, research suggests
Flat screen TVs that incorporate quantum dots are now commercially available, but it has been more difficult to create arrays of their elongated cousins, quantum rods, for commercial devices. Quantum rods can control both the polarization and color o.....»»
Small-molecule autocatalysis may have paved the way for the emergence of evolution by natural selection
The discipline of systems chemistry deals with the analysis and synthesis of various autocatalytic systems and is therefore closely related to the study of the origin of life, since it investigates systems that can be considered as a transition betwe.....»»
How secondary cities can compete with superstar cities through innovation competitiveness
Local universities, global connectivity and entrepreneurship can help secondary cities combat the geographic polarization of innovation in superstar cities, according to new research being conducted in Trinity College Dublin and Ca' Foscari Universit.....»»
New study: Political animosity is global
A new study by an interdisciplinary team of researchers across six different countries has found that affective polarization, or the tendency to dislike people who belong to opposing political parties while favoring people from their own political pa.....»»
Deep dive into Meta"s algorithms shows that America"s political polarization has no easy fix
The powerful algorithms used by Facebook and Instagram to deliver content to users have increasingly been blamed for amplifying misinformation and political polarization. But a series of groundbreaking studies published Thursday suggest addressing th.....»»
Did Facebook fuel political polarization during the 2020 election? It’s complicated.
There's strong ideological segregation, but proposed interventions didn't change attitudes. Enlarge (credit: Getty Images | Aurich Lawson) Over the last several years, there have been growing concerns about the influence.....»»
Enhancing image quality with broadband achromatic and polarization-insensitive metalenses
Precise control of light is a crucial requirement in optical imaging, sensing, and communication. Traditional lenses employed for the purpose have limitations, necessitating more precise and compact solutions. To address this need, researchers have d.....»»
On-chip infrared circular polarization detector with ultrahigh discrimination
Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ellipticity) detection is essential for chiral mole.....»»
A fresh look at the current state of financial fraud
In this Help Net Security video, Greg Woolf, CEO at FiVerity, discusses how the emergence of sophisticated fraud tools powered by AI and recent upheavals in the banking sector have forged an ideal environment for financial fraud. This complex scenari.....»»
Did the Anthropocene start in 1950—or much earlier? Here"s why debate over our world-changing impact matters
It made world news last week when a small lake in Canada was chosen as the "Golden Spike"—the location where the emergence of the Anthropocene is most clear. The Anthropocene is the proposed new geological epoch defined by humanity's impact on the.....»»
Immigration polarizes the right, and climate change polarizes the left: Study reveals Europe"s fault lines
The analysis of a representative survey conducted in ten European countries shows that affective polarization is at its greatest when it comes to "climate change" and "immigration.".....»»
New findings shed light on the chemical evolution of the Earth
The sun as a source of energy, and catalysts to accelerate chemical reactions, were of critical importance in the emergence of the first biochemical molecules on Earth. A research team has now shown that a solid deposited from ammonia and methane pla.....»»
