The study, which also explores people's belief in conspiracy theories, was conducted in cooperation with the Heinrich Böll Foundation and the Otto Brenner Foundation.
"This time we have some good news, but we must also point out that xenophobia and extreme right-wing attitudes are still at a high level - and that authoritarian and anti-democratic attitudes are a constant threat to our open, liberal society. What's more, certain ideologies are becoming entrenched," said Professor Oliver Decker.
Magnetic materials are ubiquitous in modern society, present in nearly all the technological devices we use every day. In particular, personal electronics like smartphones/watches, tablets, and desktop computers all rely on magnetic material to store information. Information in modern devices is stored in long chains of 1's and 0's, in the binary number system used as the language of computers.
Phase 1/2 randomised controlled trial of an inactivated SARS-CoV-2 vaccine candidate (CoronaVac) involved more than 700 healthy volunteers aged 18-59 years recruited in China between 16 April and 5 May 2020.
The vaccine appeared to be safe and well tolerated at all tested doses. The most common reported side effect was pain at the injection site.
Within 14 days of the final dose, study detected robust antibody responses after two injections of the vaccine candidate were given 14 days apart, even at lowest dose tested (3μg).
Movie ratings can determine a movie's appeal to consumers and the size of its potential audience. Thus, they have an impact on a film's bottom line. Typically, humans do the tedious task of manually rating a movie based on viewing the movie and making decisions on the presence of violence, drug abuse and sexual content.
A team of researchers demonstrated that popular robotic household vacuum cleaners can be remotely hacked to act as microphones.
The researchers--including Nirupam Roy, an assistant professor in the University of Maryland's Department of Computer Science--collected information from the laser-based navigation system in a popular vacuum robot and applied signal processing and deep learning techniques to recover speech and identify television programs playing in the same room as the device.
Too much or too little iron in the body can lead to disease but organisms have developed ways to keep iron levels in balance. Ferroportin, the only known iron exporter that releases iron into the blood stream, is a crucial component of iron-balancing mechanisms.
A new kind of radar could make it possible for self-driving cars to navigate safely in bad weather. Electrical engineers at the University of California San Diego developed a clever way to improve the imaging capability of existing radar sensors so that they accurately predict the shape and size of objects in the scene. The system worked well when tested at night and in foggy conditions.
The team will present their work at the Sensys conference Nov. 16 to 19.
[Vienna, Nov 18, 2020] Scientists at the Complexity Science Hub Vienna (CSH) 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 model, societies can only be either cohesive or fragmented. And just as water becomes ice or gas at a certain temperature, a society abruptly changes from one state to the other at certain tipping points.

A new material for wind blades that can be recycled could transform the wind industry, rendering renewable energy more sustainable than ever before while lowering costs in the process.
While ultrasound imaging technology has been available for more than 50 years, machine size and cost limited its reach to medical offices and hospitals. However, relatively recent advances in this technology has allowed for the development of ultra-portable handheld devices that appear more like the tricorder from Star Trek than a traditional ultrasound machine.
Researchers have developed artificial intelligence technology that brings together imaging, processing, machine learning and memory in one electronic chip, powered by light.
The prototype shrinks artificial intelligence technology by imitating the way that the human brain processes visual information.
The nanoscale advance combines the core software needed to drive artificial intelligence with image-capturing hardware in a single electronic device.
DSI postdoctoral fellow Sandrine Müller uses smartphone sensor data to study human behavior.
A research team led by Sandrine Müller, a Data Science Institute postdoctoral research fellow, and Heinrich Peters, a Columbia Business School (CBS) doctoral candidate, has linked mobility behavior to well-being by exploring associations between different kinds of mobility behaviors (e.g., time spent in transit, number of locations visited, and total distance covered) and several indicators of well-being (e.g., depression, loneliness, and stress).
Conventional observations show that spiny dogfish in the western North Atlantic rarely eat Atlantic cod. However, some believe the rebuilding dogfish populations are limiting depleted cod numbers by competition or predation. To find out what is going on, NOAA Fisheries scientists looked to genetic testing to confirm cod presence in dogfish stomachs.
2D materials, consisting of a single layer of atoms, are revolutionizing the field of electronics and optoelectronics. They possess unique optical properties that their bulky counterparts do not, spurring the creation of powerful energy devices (for example, optic fibers or solar cells). Interestingly, different 2D materials can be stacked together in a "heterojunction" structure, to generate light-induced electric current (or "photocurrent").
Fukuoka, Japan - Many applications, including carbon dioxide storage and oil recovery, involve the simultaneous flow of two or more phases of matter (solid, liquid, gas, etc.) through porous materials. Pore-scale modeling of such multiphase flow has struggled to capture important phenomena referred to as viscous coupling effects. But now, a research team has developed a method that overcomes this limitation with potential applications to improve fuel technologies and carbon capture systems.
