Brief cognitive behavioral therapy for suicide prevention 鈥� when delivered remotely via video telehealth 鈥� reduces suicide attempts and suicidal ideation. The Ohio State University Wexner Medical Center and College of Medicine led the study that is published online in the journal JAMA Network Open.
In the Journal of the Acoustical Society of America, an interdisciplinary team explored possible regularities in vocal emotional expressions by comparing expressive interjections, such as 鈥渨ow,鈥� to nonlinguistic vocalizations, such as screams and cries, from across the globe. The researchers analyzed vowels in interjections from 131 languages, comparing them with nearly 500 vowels from vocalizations produced in joyful, painful, or disgusting contexts. Each of the three emotions yielded consistent and distinct vowel signatures across cultures in vocalizations.
The airflow from an indoor badminton court鈥檚 HVAC system and cross ventilation can affect the path of a birdie and have a significant role in play, but research published in Physics of Fluids proposes that different roof configurations could help mitigate wind drift. The authors recommend that important badminton games be played on courts with a barrel roof and a ventilation opening. The team modeled the airflow in a barrel roof stadium with different ventilation opening directions and tested this against a simulation of a flat roof to understand the roof effects.
Nitrogen and potassium are fundamental nutrients for plant growth, but imbalances frequently disrupt agricultural systems. In apple orchards, low potassium can severely limit carbon and nitrogen metabolism, impairing photosynthesis and yield. Potassium availability is often reduced by environmental factors such as soil leaching, while nitrogen is frequently over-applied due to its affordability and yield-enhancing effects. Given these challenges, optimizing nitrogen and potassium levels in apple trees warrants further research to counter the negative impact of nutrient imbalances on plant health and productivity.
Batteries in electric vehicles can fail quickly, sometimes catching fire without much warning. Sandia National Laboratories is working to detect these failures early and provide sufficient warning time to vehicle occupants.
Taking antibiotics during an influenza infection can be harmful and increases the risk of developing a bacterial pneumonia while sick with the flu, according to new research led by Cedars-Sinai.
Obesity causes insulin resistance by increasing activation of the sympathetic nervous system and the release of the stress hormone norepinephrine, according to a Rutgers Health study.
A pivotal study has uncovered a genetic defense mechanism in lily plants against Botrytis cinerea, the fungus behind gray mold disease. Central to this defense is LlHSFA4, a transcription factor that, when activated, initiates a robust response against the pathogen. This discovery could transform strategies for protecting horticultural crops from severe fungal infections.
Researchers from Uniformed Services University of the Health Sciences and Duke University have developed a promising vaccine offering strong protection against chlamydia. The study, published in npj Vaccines, shows that a whole-cell vaccine protected mice from infections, helping them clear the bacteria faster and with fewer infections, potentially reviving debates on chlamydia prevention.
Pioneering research has pinpointed key vacuolar transporters in citrus fruits that regulate taste by balancing citric acid and sugar levels. This discovery illuminates the genetic pathways controlling flavor, laying the groundwork for cultivating citrus varieties with optimized sweetness and acidity鈥攁 promising development for both consumers and the agricultural sector.
