(Press-News.org) Mental illnesses are thought to be caused by both biological and environmental factors in complex interaction. Among the environmental contributors are a wide range of social, economic, and demographic factors known as “social determinants.” Adam Skinner and colleagues used dynamic Bayesian network analysis to infer the complex causal networks that link social determinants to mental health in a nationally representative sample, consisting of around 25,000 participants in the Household, Income and Labour Dynamics in Australia (HILDA) Survey. The authors identified variables that directly predicted mental health problems: physical health, loneliness, satisfaction with local community, and satisfaction with personal finances. In addition, the authors found that mental health problems influenced many of these same variables, suggesting feedback loops. According to the authors, these results can be used to identify the social and economic interventions that could most efficiently and effectively reduce mental illness at a population scale. For example, if every participant was satisfied with their financial situation, rates of mental illness would drop by around 3 percentage points, eliminating almost a third of mental illness in Australia. Significant public health gains could also be achieved by promoting local community engagement, physical wellbeing, and participation in volunteer or charity work and paid employment, perhaps through a nationally funded job guarantee program.

Study finds key role for non-neural brain cells in processing vision
2025-07-22
Cells called astrocytes are about as abundant in the brain as neurons, but scientists have spent much less time figuring out how they contribute to brain functions. A novel study by MIT researchers at The Picower Institute for Learning and Memory shows that one function appears to be maintaining the chemical conditions necessary for groups of neurons to team up to encode information.
Specifically, the neuroscientists showed that when they knocked out the ability of astrocytes in the visual cortex of mice to produce a protein called “GABA transporter 3 (Gat3),” neurons there became less able as a group to represent ...
AIPasta—using AI to paraphrase and repeat disinformation
2025-07-22
Brace yourself for a new source of online disinformation: AIPasta. Research has demonstrated that generative AI can produce persuasive content. Meanwhile, so-called CopyPasta campaigns take advantage of the “repetitive truth” effect by repeating the exact same text over and over until it seems more likely to be true by those who encounter it many times. Saloni Dash and colleagues explore how these two strategies can be combined into what the authors term “AIPasta.” In AIPasta campaigns, AI can be used to produce many slightly different versions of the same message, giving the public ...
Chung-Ang University researchers develop innovative air filter inspired by nasal hair
2025-07-22
Airborne particulate matter represents a silent but pervasive threat to our health, infiltrating our homes, workplaces, and public spaces alike. Air filters are often our primary defense against these microscopic pollutants, which include pollen, dust, and smoke.
However, conventional air filters suffer from a fundamental weakness: they rely on extremely weak adhesive forces (van der Waals interactions) to capture particles. These forces are often insufficient to effectively trap and retain fine particles, leading to poor filtration performance and the release ...
Exploring the dynamic partnership between FtsZ and ZapA protein
2025-07-22
Bacterial cell division, a process wherein a single cell divides to form two identical daughter cells, represents one of the most essential biological processes. Understanding the precise mechanism behind this dynamic process can help in the development of targeted ways to inhibit bacterial proliferation.
The process of cell division involves multiple proteins and their complex interactions. FtsZ protein molecules polymerize to form protofibrils that further associate into a ring-like structure called the Z-ring. Z-ring formation is a crucial step in the cell division process, facilitated by multiple FtsZ-associated proteins. ZapA is one such protein, which ...
Pusan National University researchers reveal new calibration framework for digital twins
2025-07-22
To manage increasingly complex manufacturing systems, involving material flows across numerous transporters, machines, and storage locations, the semiconductors and display fabrication industries have implemented automated material handling systems (AMHSs). AMHSs typically involve complex manufacturing steps and control logic, and digital twin models have emerged as a promising solution to enhance the visibility, predictability, and responsiveness of production and material handling operation systems. However, digital twins don’t always fully reflect reality, potentially affecting production performance ...
Suppressing tumor cell stemness might help colon cancer management
2025-07-22
Colon cancer remains a major global health concern, ranking third among the most diagnosed cancers and leading causes of cancer-related death worldwide. One critical factor that makes treating colon cancer challenging is the presence of cancer stem cells. Though typically present in small populations, these powerful cells drive tumor growth, resist standard treatments, and often contribute to relapse. They achieve this through their “stemness,” a set of properties that enable these cells to self-renew ...
When the city comes to you, get flexible; when you go to the city, be persistent
2025-07-22
To the point
Grackles trained to be more flexible were better at foraging afterward: They ate more foods and used more foraging techniques. Investigating their cognitive abilities in the wild shows how flexibility impacts their ability to adapt to human-modified environments.
Behavioral flexibility is not the primary facilitator of a range expansion: Although high levels of flexibility were found in two successful urban bird species, only one is rapidly expanding is range. This suggests that flexibility alone does not ...
Clearing rainforest for cattle farming is far worse for nature than previously thought, finds landmark bird survey
2025-07-22
Researchers have conducted the world’s biggest ever bird survey, recording 971 different species living in forests and cattle pastures across the South American country of Colombia. This represents almost 10% of the world’s birds.
They combined the results, gathered over a decade, with information on each species’ sensitivity to habitat conversion to find that the biodiversity loss caused by clearing rainforest for cattle pasture is on average 60% worse than previously thought.
Until now, understanding the biodiversity impact of land-use change has generally involved ...
Stem cell transplant without toxic preparation successfully treats genetic disease
2025-07-22
An antibody treatment developed at Stanford Medicine successfully prepared patients for stem cell transplants without toxic busulfan chemotherapy or radiation, a phase 1 clinical trial has shown.
While the researchers tested the protocol on patients with Fanconi anemia, a genetic disease that makes standard stem cell transplant extremely risky, they expect it may also work for patients with other genetic diseases that require stem cell transplants.
“We were able to treat these really fragile patients with a new, ...
Radiation therapy overcomes immunotherapy resistance in some cancers
2025-07-22
By sparking the immune system into action, radiation therapy makes certain tumors that resist immunotherapy susceptible to the treatment, leading to positive outcomes for patients, according to new research by investigators at the Johns Hopkins Kimmel Cancer Center Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Netherlands Cancer Institute. The work was supported by the National Institutes of Health.
In the study, published July 22 in Nature Cancer, investigators dove deep into the molecular biology of non-small cell lung cancer to pinpoint what happens on ...
