A new study found that wire-cut forensic examinations can be misleading due to the high number of comparisons made, potentially leading to wrongful convictions. The researchers recommend additional information about comparison lengths be presented in court cases involving wire-cutting evidence.
Researchers found cyclin D1 expression in patients with penile cancer (PC) is associated with clinical and histopathological features. Patients with cyclin D1 expression had lower disease-free survival compared to the cyclin D1-negative group.
Researchers found that ~60% of tissues exhibit a significant negative correlation between age and stemness score, indicating a pan-tissue decline in stemness. This study adds weight to the idea that stem cell deterioration contributes to human aging, with hematopoietic stem cells from older individuals showing higher stemness scores.
Concordia researchers use network analysis to study cognitive decline, identifying key variables that predict subtle changes in brain function. Executive function and processing speed are found to be strongly influential, with age affecting cognition differently for those with mild cognitive impairment or Alzheimer's disease.
A recent study by MIT scholars reveals that widely disseminated school quality ratings are heavily dependent on the preparation and family background of their students. The study finds that many schools with low ratings perform better than expected, and conventional ratings are highly correlated with race.
A recent study from the Hebrew University of Jerusalem uncovers notable correlations between the Indian Ocean and precipitation in the Middle East, which may lead to seasonal prediction of Fall precipitation. The research highlights a discernible upward trend in crucial Indian Ocean climate indices over the last four decades, indicatin...
A study found that people from ethnic minorities show clearer signs of depression and lower adaptability on average. The researchers also discovered correlations between area poverty levels and the proportion of ethnic minorities exhibiting these traits.
Researchers report evidence of a cosmic background of gravitational waves likely produced by the merger of supermassive black hole binaries. The signal is detected through millisecond pulsar observations and has implications for our understanding of the universe's large-scale structure.
Researchers develop innovative data compression scheme to facilitate multispeckle diffuse correlation spectroscopy with high pixel resolutions, enabling non-invasive measurement of brain blood flow. The scheme uses field-programmable gate array compression to alleviate computational burdens and expand the use of SPAD cameras in biomedi...
Research explores the complex relationship between droughts, food security, and conflict in Central America. The study finds that decreases in water availability play a major role in conflict insurgences, while stable conditions of peace are more influenced by favorable socio-economic conditions.
Researchers found that COVID-19 survivors with persistent symptoms were more likely to be sedentary, especially those experiencing breathlessness and fatigue. The study, supported by FAPESP, included 614 participants who were analyzed for physical activity and lifestyle habits.
A team of researchers from Xi'an Jiaotong-Liverpool University and other institutions has identified a flexible and user-friendly model for predicting flood frequency in a changing environment. The fractional polynomial-based regression method is more effective than existing models, which often fail to account for factors like climate ...
Researchers at KAUST develop a novel multivariate skew-elliptical link model to address the challenges of highly imbalanced health data. The new model provides a better fit to COVID-19 datasets and offers flexibility over existing models.
A recent study published in Oncotarget reveals that Nectin-4 is widely expressed in head and neck squamous cell carcinoma (HNSCC), with significant correlations to clinico-pathological parameters. Non-smokers and p16-positive HNSCC showed higher expression of Nectin-4, leading to better survival rates for positive tumors.
Researchers analyzed over 31,000 participants and 1,200 paintings to find that people prefer color compositions with unique statistical properties, unlike natural scenes.
