Comparisons across ages from 15 to 90 call into question the persistent belief that adult personality remains largely fixed. Research: Personality traits are not as stable as people think. Image credit: Ribkhan / Shutterstock In a recent study published online as a “press article” in the journal communication psychologyResearchers compared changes in personality traits to changes in other aspects of life. Historically, personality traits have been thought to be largely stable and unchanging once a person reaches adulthood. Previous research suggests that personality traits develop throughout the lifespan, and provides promising initial evidence that personality traits can be modified through…
Researchers looked at how diet, sleep, physical activity, and television viewing were related to school performance, while taking into account demographic factors and neurodevelopmental disorders. Research: Independent and combined associations of lifestyle behaviors on academic achievement in adolescents. Image credit: Pixel-Shot / Shutterstock In a recent study published online as a “press article” in the journal scientific reportA group of Spanish researchers investigated the independent and combined associations between physical activity, sleep, diet, television viewing, and academic performance in adolescents, taking into account demographic factors and neurodevelopmental disorders (NDs). background Is it possible that daily habits such as eating well,…
A vast reservoir of magma beneath Japan’s Kikai caldera appears to be filling up again, giving scientists a glimpse of how some of Earth’s largest volcanoes recover after devastating eruptions. The discovery, led by researchers at Kobe University, could improve our understanding of giant caldera systems such as Yellowstone in the United States and Toba in Indonesia. It could also help scientists identify subsurface changes that precede future mega-eruptions. Volcano capable of huge eruptions Mt. Kikai is a largely submerged volcanic caldera in the south of Japan. About 7,300 years ago, the largest known volcanic eruption of the Holocene, the…
By examining six regions of the brain at single-molecule resolution, researchers identified layers of tau pathology that were not fully captured by traditional tissue staining. Research: Nanoscale tau aggregates in Parkinson’s disease. Image credit: Peterschreiber.media / Shutterstock In a recent study published online as a “press article” in the journal npj parkinson’s diseaseresearchers used single-molecule pull-down (SiMPull) assays and super-resolution microscopy to map the nanoscale distribution of protein aggregates in postmortem human brain tissue. In this study, we specifically analyzed six different brain regions using tissue from 29 postmortem donors, where sample availability varied by region, and identified distinct populations…
Oncoformer was trained on millions of health records and chest X-rays to detect signals across cancer risk, stage, treatment response, and recurrence. Research: Advances in cancer detection and treatment using longitudinal, routine clinical data. Image credit: Lightspring / Shutterstock In a recent study published in the journal cellresearchers developed Oncoformer, an artificial intelligence (AI)-based transformer model to accelerate cancer detection and management using longitudinal electronic health records (EHRs) and chest X-rays. Developed using data from 2.81 million individuals with 11.9 million clinical visits and evaluated in independent cohorts, this framework can classify pre-existing cancers, distinguish between individuals who receive a…
In many animal tissues, stem cells continually divide to create new cells that replace old or damaged cells. However, this ability requires tight control, as uncontrolled stem cell proliferation can disrupt tissue homeostasis and contribute to tumorigenesis. Researchers at the National Institute for Physiological Sciences have identified a previously unknown mechanism that controls stem cell proliferation in the fruit fly intestine. This study revealed that smooth septum junction (sSJ) proteins, known for their role in cell-cell adhesion, regulate signaling in intestinal progenitor cell differentiation and prevent excessive stem cell proliferation. Unraveling the signals from adhesion to growth Previous studies by…
When Congress passed the Deborah Sampson Act of 2020 (named after the woman who served in the Revolutionary War as a man), the goal was to expand access to government-provided health care for women veterans. Now, one of the key provisions of that bill would create a new report on intimate partner violence among veterans and make recommendations for Veterans Affairs clinicians and policymakers. The authors convened a multidisciplinary virtual committee of more than a dozen advocates and experts representing patients, front-line medical staff, researchers, and government decision-makers. If we want to learn and move forward, our approach must…
New research published in Journal of Health Psychology suggest that searching for meaning in life without feeling a pre-existing sense of purpose is associated with a higher risk of occupational burnout. The findings show that feeling meaningful tends to protect against fatigue at work, but constantly seeking purpose has a negative impact on mental health. These insights provide a more nuanced understanding of how internal psychological needs interact with workplace stress over time. Although occupational burnout is often discussed in terms of workload, stress, and organizational pressures, personal meanings can also play an important role. Burnout is a type of…
Having a strong will can lead to continued environmentally friendly habits, but short-term changes in a person’s self-control will not directly change their environmental behavior over time. These findings, published in the Journal of Environmental Psychology, suggest that society should prioritize systems that are easy to adopt, rather than relying heavily on mental effort to promote conservation. Taking steps to reduce environmental damage requires considerable mental effort in daily life. Actions like taking recyclables to a specific bin, waiting for public transport, and reducing energy use at home often mean resisting easier or more convenient options. Psychologists describe this ability…
The expulsion of five diabetes experts from last month’s American Diabetes Association meeting continues to resonate, with more than 200 members now calling for the resignation of two ADA leaders. In response, the ADA released its own message on Tuesday, thanking its members for their patience while the report was written. The resignation request, sent in an open letter to the ADA board last week, calls for the removal of CEO Charles Henderson and chief scientific and medical officer Rita Kalyani. It also calls for an “independent investigation into the events of the 2026 New Orleans Scientific Sessions, a full…
