Nursing home residents with cognitive impairment more likely to be admitted to hospital

A study from Regenstrief Institute and Indiana University School of Medicine found that nursing home residents with cognitive impairment are more likely to be admitted to the hospital after an emergency department visit. The factors most associated with discharge back to the facility were falls, trauma or fracture, bleeding, and pain.

Projecting favorable perceptions of space

Project Man in Space, initiated by social psychologist Donald Michael in 1955, aimed to capture public opinion on space exploration. The program's research revealed strong interest in Sputnik and influenced public support for new initiatives, but also perpetuated utopian narratives that obscured military applications.

Children with autism, ADHD have more doctor and hospital visits during infancy

Research from Duke University Medical Center found that children with autism spectrum disorder and attention deficit hyperactivity disorder visit doctors more often in their first year of life. This suggests a potential new method for identifying the conditions earlier, which could lead to improved outcomes and reduced healthcare costs.

CRISPR-induced immune diversification in host-virus populations

A new study reveals that CRISPR-induced immune diversification in host-virus populations leads to the emergence of weighted-nestedness immunity structure, enabling hosts to control virus diversification. This structure is crucial for understanding eco-evolutionary dynamics and designing stable microbial populations.

More than 'just a fish' story

Researchers identify genetic diversity among Neosho and Northern smallmouth bass subspecies, emphasizing importance of origin when stocking streams to avoid 'genetic swamping.' The study's findings could inform fisheries management strategies to preserve native populations and prevent dominant subspecies from outcompeting others.

Driver of the largest mass extinction in the history of the Earth identified

A new study reconstructs the Permian-Triassic boundary event, revealing that massive volcanic activities in Siberia triggered the extinction of 95% of ocean life. The team used fossil brachiopod shells to analyze isotopes and simulate Earth's processes, concluding that warming and acidification led to catastrophic consequences.

High pressure is key for better optical fibers

Researchers from Hokkaido University and the US used computer simulations to show that high pressure can reduce light scattering in silica glass fibers by over 50%. This could enable longer distance data transmission without amplification, revolutionizing global communication.

Brain circuit biomarkers to predict response to treatment for neuropsychiatric disorders

Researchers identify distinct functional connectivity patterns in brain circuits using EEG, enabling subtyping of patients independent of clinical diagnosis. These patterns can predict treatment outcomes, with some subtypes responding better to psychotherapy or medication while others benefit from non-invasive TMS treatment.

New evidence to guide the practice of blood transfusions in children with severe malari

A new study led by ISGlobal found that blood transfusions can increase the survival of children with severe malaria, even at higher haemoglobin levels than recommended thresholds. In cases with complications, such as impaired consciousness or acidosis, transfusion improved survival even at high haemoglobin levels.
