Abortion Bans and Medical Care for Miscarriage
State-level abortion bans in the United States are linked to a reduction in access to evidence-based medical care for miscarriage management. This has resulted in more women being forced to carry non-viable pregnancies, potentially jeopardizing their health and fertility and prolonging grief.
Leucovorin and Autism Spectrum Disorder (ASD)
Following a declaration by President Donald Trump and other health officials last September, a new study reveals that many families believed leucovorin to be an effective treatment for autism spectrum disorder (ASD), despite a lack of supporting data.
Risk-Taking Behavior and Decision-Making in Traffic
Children who engage in risk-taking play demonstrate faster and more informed decision-making skills when navigating traffic situations.
Aerospace Engineering and Aircraft Blade Reliability
Researchers have made a significant advancement in aerospace engineering by combining gallium⁺ and xenon⁺ ion beams (FIB-DIC) to map mesoscale residual stresses in titanium aircraft blades. This multiscale approach significantly improves engine reliability.
Data Center Waste Heat as an Urban Thermal Hazard
The thermal impacts of data centers are emerging as a concern in urban environments. Initial field measurements indicate that data center waste heat can contribute to elevated neighborhood-scale air temperatures.
Rice Drought Tolerance and Genetic Variation
Comprehensive phenotypic, physiological, and genetic analyses have revealed stronger seedling-stage drought tolerance in the Xian/indica rice variety compared to the Geng/japonica rice variety.
Cancer Cell DNA Transfer
Research has uncovered a mechanism by which damaged DNA can spread between human cells via tube-like structures. If cancer cells utilize this process, harmful mutations could potentially transfer from cancer cells to healthy cells.
Air Pollution and Lung Function/Brain Activity
Short-term exposure to common air pollutants has been shown to have distinct impacts on both lung function and brain activity. Growing evidence suggests a link between long-term exposure to elevated levels of air pollution and an increased risk of dementia.
Obesity Trends in High- and Low-Income Countries
Obesity rates have plateaued or slightly declined in several high-income countries. However, obesity continues to rise in most low- and middle-income countries, surpassing prevalence levels previously observed in wealthier nations.
Genetic Division of Indonesia
Analysis of ancient genomes has helped to reconstruct the genetic division of Indonesia into distinct western and eastern populations.
Reversal of High-Fat, High-Sugar Diet Effects in Animals
A systematic review and meta-analysis of animal studies indicates that the cognitive and behavioral effects of reversing a high-fat, high-sugar diet can be observed.
Neuroepithelial Tumor and Gene Therapy
A case report in the New England Journal of Medicine details a neuroepithelial tumor that developed after intracisternal delivery of an adeno-associated virus (AAV) gene therapy.
School Belonging and Teenagers' Mental Health
Feeling a sense of belonging at school and having positive relationships with teachers can protect teenagers' mental health.
Dopamine Receptors and Brain Cell Migration
Scientists have discovered that dopamine receptors act as signaling mechanisms to guide the migration of brain cells during development.
Europa's Vapor Plumes: Revisiting Evidence
A reanalysis of data has led scientists to reconsider the existence of vapor plumes on Jupiter's moon Europa. The confidence in the plumes' existence has been reduced from 99.9% to less than 90%, deemed insufficient evidence for certainty.
Political Alignment and Racial Resentment
White Americans who feel they are on the losing side of politics are more likely to oppose economic redistribution programs, particularly when comparing their political standing to that of racial minorities. Racial resentment appears to be a significant driver of conservative political beliefs among White Americans, even those who are not religiously conservative.
