(Press-News.org) About The Study: In this cohort study of 715 U.S. hospitals from 2019 to 2024, risk-adjusted in-hospital mortality declined significantly following the COVID-19 pandemic, resuming its prepandemic trajectory of improvement, while patient acuity as measured by case mix index remained elevated. These findings suggest a new postpandemic baseline for patient acuity, whereas hospital mortality outcomes have returned to prior improvement trends.

Functional somatic disorders in individuals with a history of sexual assault
2025-11-12
About The Study: The findings of this cohort study suggest that sexual assault may increase the risk of developing functional somatic disorder (FSD), involving multiple body systems. Functional somatic disorder is characterized by persistent physical symptoms and substantial disability. Despite limitations from small case samples in some FSD subtypes, the pooled analysis underscores the high risk of FSD, emphasizing the critical need for further research and targeted interventions to address the long-term biopsychosocial consequences of sexual assault.

Variety of animals evolved similar genetics solutions to survive on land, study finds
2025-11-12
Animals from completely different branches of the tree of life such as insects, worms and vertebrates independently evolved similar genetic solutions to survive on land, according to a new study from researchers at the University of Bristol and University of Barcelona.
The research, published in Nature today [12 November] suggests that some adaptations are so essential that environmental challenges make evolution predictable.
The researchers decoded the genetic basis of one of evolution’s more extraordinary innovations – ...
Nature versus nurture question addressed in landmark study
2025-11-12
Genome sequencing has been used to determine how much genes influence human characteristics including height and weight, and susceptibility to diseases like Type 2 diabetes, in a study co-led by University of Queensland researchers and collaborators at genomic technology company Illumina, Inc.
This study is the largest of its kind and used the DNA sequences of 347,630 people of European descent from the UK Biobank to quantify how much trait differences between people can be explained by genetic factors, known as heritability.

AI can deliver personalized learning at scale, study shows
2025-11-12
A new Dartmouth study finds that artificial intelligence has the potential to deliver educational support that meets the individual needs of large numbers of students. The researchers are the first to report that students may put more trust in AI platforms programmed to pull answers from only curated expert sources, rather than from massive data sets of general information.
Professor Thomas Thesen and co-author Soo Hwan Park tracked how 190 medical students in Dartmouth's Geisel School of Medicine used an AI teaching assistant called NeuroBot TA, which provides around-the-clock individualized support for students in Thesen's Neuroscience and Neurology course.

Study: Plant-based diet can prevent, reverse form of heart disease in animals with hypertension
2025-11-12
ATLANTA — Eating a plant-based diet consisting of fruits, vegetables, nuts and legumes can help prevent and reverse heart disease in rats that have high blood pressure, according to a study published by researchers in the Institute for Biomedical Sciences at Georgia State University.
The basic research study, published in the Journal of the American Heart Association, tested whether coronary microvascular dysfunction (CMD), a type of heart disease that occurs when there’s damage to the tiny blood vessels that regulate blood ...
Lower LRIG1 expression linked to aggressive gliomas
2025-11-12
“Our results reinforce suggestions that LRIG1-3 could function as diagnostic markers and therapeutic targets in the treatment of gliomas.”
BUFFALO, NY – November 12, 2025 – A new research paper was published in Oncotarget (Volume 16) on November 6, 2025, titled “LRIG1-3 in gliomas: LRIG1 protein expression decreased in higher grade gliomas.”
In this study by Marlene Happe, Saskia Kuhl, Lukas Görtz, Roland Goldbrunner and Marco Timmer, from the University of Cologne, researchers found that the LRIG1 protein, which may help suppress tumors, is present at lower levels in more aggressive gliomas, a type of brain tumor. The findings ...
National consortium project led by TU Delft receives huge grant from NWO to build world's largest research digital twins for energy systems
2025-11-12
A cutting-edge consortium project called Understanding large and cOmplex Power sYstems (UTOPYS) will enable researchers to build the world’s largest research cluster for real-time energy system studies. The project is led by Principal Investigator Prof. Peter Palensky of TU Delft, and is comprised of eight Dutch research organisations, and SURF - the IT cooperative of education and research. It has been awarded a huge grant of 16.5 million euros through the Large-Scale Research Infrastructure ...
Intranasal oxytocin and physical intimacy for dermatological wound healing and neuroendocrine stress
2025-11-12
About The Study: This study found that intimate physical contact can reduce cortisol responses and, along with oxytocin administration, promote wound healing. These findings provide a foundation for future interventions that integrate relationship dynamics and neurohormonal modulation to improve health and recovery from illness.

Scientists make dark exciton states shine, unlocking new frontiers for nanotechnology
2025-11-12
New York, November 12, 2025 — A research team at the City University of New York and the University of Texas at Austin has discovered a way to make previously hidden states of light, known as dark excitons, shine brightly, and control their emission at the nanoscale. Their findings, published today in Nature Photonics, open the door to faster, smaller, and more energy-efficient technologies.
Dark excitons are exotic light-matter states in atomically thin semiconductors that typically remain invisible because they emit light very weakly. These states, however, are highly ...
