(Press-News.org) Moral values such as purity and loyalty are often linked with hateful language, according to a study. Scholars in the field of Natural Language Processing (NLP) have in recent years focused on improving the automated detection of hate speech so such language can be removed from online spaces. But some scholars have argued that mere detection is not a real solution—that NLP can and should be used to investigate the roots of hateful language. Morteza Dehghani and colleagues conducted three studies of hateful language, looking at speeches and texts written by leaders of the Nazi party between 1933 and 1945, hateful slurs in large text corpora across a multitude of languages, and hate speech from 2018 on the far-right social-media platform Gab. In each analysis, the authors used NLP to situate hate speech in the context of moral motivations, worldviews, and rationales. The authors used Moral Foundations Theory as their overarching framework. Moral Foundations Theory posits that moral sentiments can be classified into a small number of core values, including care, fairness, loyalty, authority, and purity. The authors found that Nazi propaganda appealed to the ideal of purity, in the sense that members of out-groups were depicted as impure and polluting. In the large multi-lingual corpora, hateful language was highly associated with words related to the ideal of loyalty. And on Gab, purity was again the most invoked value in hateful posts. Morality and hate may be deeply linked in the human psyche, according to the authors. Alternatively, or in addition, moral arguments may be used to legitimize hateful opinions. The authors call for additional research into the link between morality and hate.

Decoding the impact flash
2023-07-11
An experimental study explores the visible impact flash created by high velocity impacts. Impacts by debris and meteoroids pose a significant threat to satellites, space probes, and hypersonic craft. Such high-velocity impacts create a brief, intense burst of light, known as an impact flash, which contains information about both the target and the impactor. Gary Simpson, K.T. Ramesh, and colleagues explored the impact flash by shooting stainless steel spheres into an aluminum alloy plate, at a speed of three kilometers per second — about 6,700 miles per hour, or more than nine times the speed of sound. The resulting impact flashes were photographed ...
SwRI delivers plasma spectrometer for Moon mission
2023-07-11
SAN ANTONIO — July 11, 2023 —Southwest Research Institute has delivered a plasma spectrometer for integration into a lunar lander as part of NASA’s Lunar Vertex investigation, scheduled to commence next year. The target site is the Reiner Gamma region on the Moon’s nearside, a mysterious area known to have a local magnetic field. The SwRI-developed Magnetic Anomaly Plasma Spectrometer (MAPS) will study the interaction of the solar wind with surface materials on the Moon, aiming to understand the origin of the sinuous patterns of ...
Efficient X-ray luminescence imaging with ultrastable and eco-friendly copper(I)-iodide cluster microcubes
2023-07-11
Scintillators are optical materials that emit low-energy ultraviolet and visible photons in response to ionizing radiation such as X-rays and gamma rays. This property makes scintillating materials useful for applications like non-destructive testing, X-ray astronomy, security inspection, and medical imaging.
In a recently published paper in Light Science & Applications, Professor Xiaowang Liu and Academician Wei Huang, along with their team from the Institute of Flexible Electronics at Northwestern Polytechnical University, ...

Xerces Blue butterfly genome sequenced, an icon of anthropogenic extinction
2023-07-11
The Xerces Blue butterfly (Glaucopsyche xerces) was native to the coastal dunes of San Francisco, in the United States. As the city grew, much of the butterfly’s habitat was destroyed and its population was relegated to Golden Gate National Park. Its wings were a deep iridescent blue, with characteristic white spots on the ventral side. The last surviving specimens of the species were found in 1941, by entomologist W. Harry Lange. It is considered the first insect species to have become extinct in historical times. Its disappearance has made it a global icon of anthropogenic extinction, to ...
Bacteria in kitchen may not be as harmful as you think
2023-07-11
Washington, D.C. – Bacteria found in 74 kitchens spread among 5 European countries were mostly harmless according to new research published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
“We have previously found considerable variations in kitchen standards, food preparation practices, and cleaning regimes between France, Norway, Portugal, Romania, and Hungary,” said Birgitte Moen, Ph.D., Scientist—Department of Food Safety and Quality, Nofima—Norwegian Institute of Food, Fisheries, and Aquaculture Research, Ås, Norway.

SEATTLE — July 11, 2023 — Today, scientists from the Allen Institute for Neural Dynamics, a division of the Allen Institute, launched the world’s first completely open- and crowd-sourced neuroscience experiment—inviting researchers from around the world to publicly design a shared experiment that will run on the Allen Brain Observatory, as part of the Institute’s OpenScope program. Experiments will probe ...
Marine fossils are a reliable benchmark for degrading and collapsing ecosystems
2023-07-11
Biologists attempting to conserve and restore denuded environments are limited by their scant knowledge of what those environments looked like before the arrival of humans. This is especially true of coastal ecosystems, many of which had already been drastically altered by pollution and overharvesting hundreds of years before scientists began monitoring them.
According to a new study published in the journal PeerJ, a faithful analogue of modern marine ecosystems lies just beneath the surface. Building on more than 20 years of conservation paleobiology, the results suggest that fossils of various marine groups — including worms, mollusks, crabs and sea urchins — are ...

The ground is deforming, and buildings aren’t ready
2023-07-11
There is a “silent hazard” lurking underneath our major global cities, and our buildings were not designed to handle it.
A new Northwestern University study has, for the first time, linked underground climate change to the shifting ground beneath urban areas. As the ground heats up, it also deforms. This phenomenon causes building foundations and the surrounding ground to move excessively (due to expansions and contractions) and even crack, which ultimately affects structures’ long-term operational performance and durability. Researchers also report that past building damage ...
