(Press-News.org) Bethesda, MD (Sept. 2, 2025) — Two new papers from Clinical Gastroenterology and Hepatology and Gastroenterology shed light on how gut-brain interactions, influenced by both biology and life circumstances, shape eating behaviors. Together, they highlight the importance of multidisciplinary, personalized approaches to digestive health and nutrition.
Social determinants of health and the gut-brain-microbiome axis in obesity
Researchers found that stress from life circumstances can disrupt the brain-gut-microbiome balance. This disruption may alter mood, decision-making, and hunger signals — increasing the likelihood of craving and consuming high-calorie foods.
The paper examined how social factors, such as income, education, health care access, and biological aspects, interact with the brain-gut-microbiome to influence eating habits and obesity.
By understanding these interactions, clinicians can better tailor treatment and support to individuals living with obesity, ultimately enhancing outcomes and quality of life.
Avoidant/restrictive food intake disorder symptoms in adults with disorders of gut-brain interaction
In the first general population study of its kind, researchers found that adults with disorders of gut-brain interaction are significantly more likely to screen positive for symptoms of avoidant/restrictive food intake disorder.
Key findings:
More than one-third of adults with disorders of gut-brain interaction screened positive for avoidant/restrictive food intake disorder symptoms.
Symptoms include sensory-based food avoidance, lack of interest in eating, and fear of aversive consequences.
These individuals experience significantly greater health burdens and reduced quality of life — regardless of body mass index.
The study highlights the need for routine avoidant/restrictive food intake disorder screening and integrated GI-mental-nutritional health care to better support patients with disorders of gut-brain interaction.
Key takeaway: These papers show that gut-brain communication is central to eating behavior disorders and that non-biological stressors — like discrimination or past illness — can shape physiological responses. Clinical tools must address not just what patients eat, but why.

Meal timing in later life may matter for health and longevity
2025-09-04
As we age, what and how much we eat tends to change. However, how meal timing relates to our health remains less understood. Researchers at Mass General Brigham and their collaborators studied changes to meal timing in older adults and discovered people experience gradual shifts in when they eat meals as they age. They also found characteristics that may contribute to meal timing shifts and revealed specific trajectories linked to an earlier death. The results are published in Communications Medicine.
“Our research suggests that changes in when older adults eat, especially ...
“Cracks in the system” driving high suicide rates for autistic people
2025-09-04
A new study, led by the University of Cambridge in collaboration with Bournemouth University, shows that autistic people identify loneliness, hopelessness and feelings of worthlessness and failure as key factors underpinning their suicidal feelings. Individuals who highlighted being unable to access the support they needed were more likely to have attempted suicide. Autistic women and gender minorities were disproportionately over-represented among those who struggled to access support.
The study, published in the journal Autism ...
Biodegradable PET alternative bioproduced at unprecedented levels
2025-09-04
The PET-alternative PDCA is biodegradable and has superior physical properties. A Kobe University team of bioengineers engineered E. coli bacteria to produce the compound from glucose at unprecedented levels and without byproducts — and opened up a realm of possibilities for the future of bioengineering.
The durability of plastics is both the reason why they have become so wide-spread and why they pose environmental problems. In addition, they are mainly sourced from petroleum, making them non-renewable and contingent on geopolitics. Research groups worldwide work on both biodegradable ...
NTU Singapore scientists develop cooling sunscreen from pollen
2025-09-04
Materials scientists from Nanyang Technological University, Singapore (NTU Singapore) have invented the world’s first pollen-based sunscreen derived from Camellia flowers.
In experiments, the pollen-based sunscreen absorbed and blocked harmful ultraviolet (UV) rays as effectively as commercially available sunscreens, which commonly use minerals like titanium dioxide (TiO₂) and zinc oxide (ZnO).
In laboratory tests on corals, commercial sunscreen induced coral bleaching in just two days, leading ...
Efficient ethane separation from natural gas using ZIF-8 slurry
2025-09-04
A team from China University of Petroleum (Beijing), led by Professors Guangjin Chen and Chun Deng, has developed a novel slurry-based absorption–adsorption–desorption process for natural gas separation, combining gas–liquid equilibrium experiments with mathematical modeling.
“What excites us is that our model predictions closely matched the experimental data, with an average relative error of only about 3%,” said Prof. Deng. “This gives us confidence to apply the process in practical gas separation.”
By embedding the model into a multi-objective optimization framework ...
Flying blind: aviation experts call for more pilot training amid poor general aviation safety record
2025-09-04
A new study shows that piloting a light aircraft remains an inherently risky business, accounting for over 90% of aviation-related fatalities*.
Private air travel – termed ‘general aviation’ as opposed to commercial flights or freight operations – has a poor safety record, with significantly higher accident rates compared to commercial aviation.
In a review of 46 studies exploring fixed-wing general aviation accidents, aviation researchers from the University of South Australia (UniSA) have shed new light on persistent safety ...
Unraveling the complex relationship between trade openness and carbon emissions in Asia
2025-09-04
In the ongoing debate about the impact of trade openness on environmental sustainability, a new study titled "Trade Openness and Carbon Emissions Using Threshold Approach: Evidence from Selected Asian Countries" offers fresh insights. This research explores the nuanced relationship between trade openness and carbon emissions, providing valuable evidence from a selection of Asian countries. By employing a threshold approach, the study aims to uncover the conditions under which trade openness can either exacerbate or mitigate carbon emissions.
The impact of trade openness ...

Durham University scientists have unveiled a major advance in drone swarm technology that could transform the way unmanned aerial vehicles (UAVs) are used in real-world missions.
Their newly developed system, known as T-STAR, allows swarms of drones to fly faster, safer, and with unprecedented coordination, even in highly complex and obstacle-filled environments.
Drone swarms have long been seen as the future of applications such as search and rescue operations, disaster response, forest fire monitoring, environmental ...
New research reveals insights into linkage between menopause and cardiovascular health
2025-09-04
Deep in the Bolivian Amazon exists a forager-horticultural community called the Tsimane. Researchers look to them for insights on how the human body functioned prior to modern technologies, as their lifestyles remain the closest to that of our ancestors. Oftentimes researchers find how we have navigated away from our evolutionary path, such as the Tsimane having the lowest rates of dementia, the healthiest hearts, and low late-age inflammation than those living in industrialized nations. But, new research from Arizona State University, has discovered a universal experience – post-menopausal women experiencing increased blood lipid levels, such as cholesterol.
