'I'm a Mac' -- so what? Study finds way to measure brand personality appeal

Researchers from North Carolina State University developed a system to measure brand personality appeal (BPA), allowing companies to understand how favorably their brand is viewed by consumers. The BPA framework assesses three components: favorability, originality, and clarity, grading brands on their overall appeal.

Research shows men tend to leap to judgment where women see more shades of gray

A study by researchers at the University of Warwick found that men are more likely to categorize objects as fully or not fully fitting into certain categories, whereas women tend to see more nuances and assign partial classifications. This sex difference in semantic categorization may have implications for decision-making and diagnosis.

New biomarker allows early detection of adverse prognosis after acute kidney injury

A new biomarker called NGAL in urine or blood detects early subclinical AKI and its adverse outcomes in critically ill patients, allowing for earlier conventional medical interventions. The study's findings justify redefining what defines AKI and recommend using NGAL-based testing to improve prognosis.

Do-not-resuscitate orders associated with poor surgical outcomes even for non-emergency procedures

A recent study published in Archives of Surgery found that patients with do-not-resuscitate (DNR) orders have a higher risk of poor surgical outcomes, including increased mortality rates and complication rates. The study analyzed data from over 120 hospitals and found that nearly a quarter of DNR patients died within 30 days of surgery.

Predicting premature birth possible through markers in mother's blood

Researchers at Brigham Young University and the University of Utah have developed a blood test that can identify high-risk pregnancies for pre-term birth with high accuracy. The test detects three new peptide biomarkers that signal increased risk, allowing for early intervention and potentially prolonging pregnancy by one or two weeks.

Research turns the world upside down

A recent study published in PLOS ONE found that the human brain is wired to recognize familiar objects, including faces and animals, in their typical upright orientation. The research used fMRI scans to measure brain activity in response to camouflaged faces and animals, revealing a strong bias towards recognizing upright visuals.

Innovative screening method identifies possible new treatment for fatal childhood disease

Researchers at Columbia University Irving Medical Center have developed an innovative yeast-based screening method to identify a possible new treatment for the fatal childhood disease NP-C. The approach, known as 'exacerbate-reverse', has shown promising results in repairing genetic pathways that exacerbate lethality in yeast models.

For family violence among adolescents, mattering matters

A new study led by Brown University sociologist Gregory Elliott found that adolescents who believe they matter to their families are less likely to threaten or engage in violence against family members. The research reveals a strong correlation between feeling mattered and reduced violent behavior among adolescents.

Risk of gallbladder disease virtually the same with newer and older types of birth control pills

A recent study published in Canadian Medical Association Journal found no clinically significant difference in the risk of gallbladder disease among women using different formulations of oral contraceptives. The study, which followed over 2.7 million women, suggested that reporting bias may contribute to perceived increased risk associ...

Mercury on the rise in endangered Pacific seabirds

Researchers tracked increases in methylmercury levels in black-footed albatross feathers over 120 years, attributing them to human-generated emissions. The study highlights the importance of conservation efforts in the Pacific Ocean, where mercury pollution poses a significant threat to endangered seabird species and human health.

Tinnitus caused by too little inhibition of brain auditory circuits, Pitt-led study says

A new study from the University of Pittsburgh School of Medicine reveals that tinnitus is caused by a lack of inhibition in key neural pathways of the brain's auditory center. The research suggests that increasing GABA-mediated inhibition may be an effective treatment for tinnitus, and a potential new approach to drug development.
