How beliefs about demons shape the experience of mental illness

For some evangelical Christians, attributing mental illness to demonic forces can offer a sense of meaning, while for others, it creates harmful barriers to medical care. A recent qualitative study published in Spirituality in Clinical Practice outlines how these widespread spiritual explanations act as a double-edged sword for individuals experiencing psychological distress. The research indicates that integrating religious beliefs with standard psychiatric care may be a safer path forward for many faith communities.

Religion frequently shapes how people interpret their physical and mental health. Psychologists recognize that religious frameworks offer a primary system for individuals to make sense of the world around them. By relying on theological teachings, people construct meaning around their personal suffering. This process of religious meaning construction can influence health outcomes in both positive and negative directions.

Within evangelical Christianity, foundational teachings often emphasize the active existence of spiritual forces. This includes the belief that angels, demons, and other supernatural entities directly influence the physical world. This worldview can lead to the belief that spiritual forces cause human ailments, including severe psychological distress.

Demon face syndrome: The science behind prosopometamorphopsia

Imagine looking at a loved one and seeing their face twist into a demonic, unnatural shape. Their eyes might stretch to the sides of their head, their nose might swell, and deep, unnatural grooves might appear across their cheeks and forehead. This terrifying visual experience belongs to a rare neurological condition known medically as

In popular media and online discussions, it is sometimes referred to as “demon face syndrome.” People with this condition see human faces as severely distorted, even though their vision for everyday objects remains completely normal.

Prosopometamorphopsia is fundamentally different from a hallucination. A hallucination involves seeing something that is not actually present in the physical world. People experiencing these facial distortions are looking at a real person standing in front of them. Their brain simply alters the shape, size, color, or position of the facial features before the image reaches their conscious awareness.

Cyclic catalysts use sunlight and air to regenerate during pharma ingredient synthesis

In chemical processes for producing pharmaceuticals, catalysts are a core technology that determines production speed and cost. However, until now, there has been a trade-off between “precise but disposable catalysts” and “reusable catalysts.” A KAIST research team has developed an eco-friendly catalytic technology that combines these two types, operating solely with light and air. This opens a pathway to producing pharmaceutical ingredients more cheaply and cleanly, with expected reductions in carbon emissions and environmental pollution. The study is published in the Journal of the American Chemical Society.

A research team led by Professor Sang Woo Han of the Department of Chemistry has succeeded in combining two different types of catalysts into one system. One is a silver (Ag)-based catalyst that operates in a solid state, and the other is an organic photocatalyst, DDQ (a substance that triggers chemical reactions upon absorbing light), which operates in solution.

By enabling these two catalysts to function together, the team made it possible to carry out previously difficult reactions more efficiently.

Quasi-liquid layer controls growth mechanisms of ice-like materials

Clathrate hydrates are crystalline structures formed at the bottom of seafloors, created by water molecules trapping methane, carbon dioxide or other molecules. While these materials are underutilized in technology, a University of Oklahoma researcher is helping scientists better understand them through a trailblazing study.

Alberto Striolo, a professor in OU’s Gallogly College of Engineering, co-authored an article published in the Proceedings of the National Academy of Sciences that addresses a key challenge toward utilizing hydrates: their slow growth rates. He and his fellow researchers have discovered an unusual interfacial layer on the hydrate that impacts its growth rate.

Striolo is the college’s Asahi Glass Chair in Chemical Engineering and Lloyd and Jane Austin Presidential Professor. He is also the director of the college’s Online Master of Science in Sustainability and the Materials Science and Engineering doctoral program.

Integrated strategy unlocks 29.76% efficiency for all-perovskite tandem solar cells

Two stacked layers comprise tandem solar cells (TSCs), with each subcell absorbing different wavelengths of sunlight, which makes TSCs more efficient than single-layer solar cells. All-perovskite TSCs hold great promise for next-generation photovoltaics, with a theoretical efficiency exceeding 40%. However, their practical performance is hampered by mismatched crystallization kinetics between their wide-bandgap (WBG) and narrow-bandgap (NBG) subcells, leading to phase segregation and defect accumulation.

To address this challenge, a research group led by Prof. Ge Ziyi and Prof. Liu Chang from the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences has developed an innovative colloidal chemistry strategy to enhance the performance of these TSCs, achieving a power conversion efficiency (PCE) of 29.76%. Their study is published in Joule.

The researchers designed a unified carboxylate-based modulator system using two graded carboxylate anions—tartrate (Ta-) and citrate (Cit-)—to precisely regulate the nucleation dynamics of the two subcells.

Masters of Imitation: How Hackers and Art Forgers Perfect the Art of Deception

Just as de Hory reused old canvases and pigments to make his paintings appear more authentic, attackers employ similar methods in the digital realm, leveraging trusted tools and credentials to make their malicious activity blend in. And while mimicry-based techniques have long been a staple of the attacker’s playbook, over the past couple of years, they have gotten more sophisticated. Living-off-the-Land (LotL) attacks and AI-augmented attack tooling have raised the bar for fakery. CrowdStrike’s 2026 Global Threat Report states that 81% of attacks are now malware-free, relying instead on legitimate tools and techniques, which is the hallmark of LotL tactics. Spotting these fakes quickly isn’t just an option: it’s one of the best chances to disrupt an attack before it causes real harm.

Autonomous or semi-autonomous, these generate fake identities, code, and mimic behaviors at scale.

De Hory had a complex support network to sell his paintings, involving art dealers and other representatives across many countries and cities. When some potential buyers became suspicious, he started selling his works under a variety of pseudonyms. This is similar to what is now happening with the use of inexpensive AI agents. These aren’t just used to forge believable identities to conduct fraud, but are now used to produce exploit code to exfiltrate secrets and scripts to infect endpoints, forming the basis of a larger-scale attack. Sophisticated, self-learning agents observe network behavior and continuously tune their own traffic, mirroring their patterns to fool anomaly detections. They shift C2 traffic into bursts that coincide with legitimate spikes and manipulate their signals just enough to avoid standing out. And legitimate agents are being used as orchestrators of other exploit tools to automate and scale up attacks.

Scientists Just Broke the Solar Power Limit Everyone Thought Was Absolute

A new “energy-multiplying” solar breakthrough could push efficiency beyond 100% and transform how we capture sunlight.

Solar energy is widely seen as a key tool in reducing reliance on fossil fuels and slowing climate change. The Sun delivers a vast amount of energy to Earth every second, but today’s solar cells can only capture a small portion of it. This limitation comes from a so-called “physical ceiling” that has long been considered unavoidable.

Breakthrough spin-flip technology boosts solar efficiency.

Earth’s 40,000-year tilt cycle links Antarctic ice growth to subtropical productivity

Cycles in the growth and decay of Antarctica’s ice sheets once shaped marine biological productivity thousands of miles away in the subtropical ocean, according to new research led by scientists at the University of Wisconsin-Madison. The study, published in the Proceedings of the National Academy of Sciences, found that the obliquity cycle—a 40,000-year astronomical cycle tied to changes in Earth’s axial tilt—influenced ocean productivity in subtropical latitudes about 34 million years ago, when the Antarctic ice sheet was first expanding.

The finding surprised researchers because the 40,000-year cycle, while an important factor in the conditions at Earth’s poles, typically has a more limited influence on climate and ocean conditions near the equator.

“We generally expect other astronomical cycles to have a greater influence,” says Stephen Meyers, a professor of geoscience at UW-Madison and one of the study’s lead authors.

Extremely rare second-generation star discovered inside ancient relic dwarf galaxy

Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun. This signature makes it the clearest example of a star within a primordial system that preserves the chemical enrichment of the universe’s first stars. PicII-503 also has an extreme overabundance of carbon, providing the missing link to connect carbon-enhanced stars observed in the Milky Way halo to an origin in ancient dwarf galaxies.

Astronomers have discovered one of the most chemically primitive stars ever identified—an ancient stellar relic that preserves the chemical imprint of the very first stars in the universe. This star, named PicII-503, resides in the tiny, ultra-faint dwarf galaxy Pictor II. The discovery was enabled by the U.S. Department of Energy-fabricated Dark Energy Camera (DECam), mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope, at NSF Cerro Tololo Inter-American Observatory (CTIO) in Chile, a Program of NSF NOIRLab.

Pictor II is located in the constellation Pictor. It contains several thousand stars and is more than ten billion years old. PicII-503 lies on the outskirts of the galaxy, and it contains less iron than any other star ever measured outside of the Milky Way, while also having an extreme overabundance of carbon. These signatures unmistakably match those of carbon-enhanced stars found in the outer reaches of the Milky Way, whose origins have, until now, been a mystery.
