Healing takes a ‘toll’ and how mental health providers cope matters
2025-08-19
Mental health providers are trained to guide others through trauma, yet their own exposure to clients’ suffering can take a significant toll. Studies show that between 40% and 85% of providers experience compassion fatigue or secondary traumatic stress – key signs of reduced professional quality of life. These stressors are often ongoing and layered, and when combined with limited coping tools and a sense that they have little control over their circumstances, the impact can be even greater.
Researchers from Florida Atlantic University examined how different coping styles affect the relationship between a provider’s sense of control over ...

Mapping West Nile virus risk
2025-08-19
West Nile virus (WNV) has been the dominant cause of mosquito-borne illness in the United States since its introduction into North America in 1999. There are no vaccines nor medications to prevent or treat illness in people, so surveillance, prevention, and control remain the best options to protect the public. Mosquito surveillance for WNV is a central component of the public health response, but this approach is labor intensive and limited by practical constraints on the number of locations that can be sampled. To address this limitation, Joseph McMillan and colleagues developed a validated machine learning model that uses freely ...
Extreme heat increases infant mortality in Sub-Saharan Africa
2025-08-19
Sub-Saharan Africa currently has the highest infant mortality rate in the world, with 27 babies out of every 1,000 live births dying in their first month. As the climate warms, pregnant women in the region are increasingly exposed to extreme heat, which can cause reduced placental blood flow and dehydration, potentially affecting fetal development. In addition, extreme heat can lead to the proliferation of pathogenic bacteria in the environment, and can make it difficult for women to travel to prenatal care appointments. Jiafu An and colleagues sought to determine whether in-utero exposure to extreme ...

Evaluating FAST walk system for neuromodulation-assisted gait recovery in chronic stroke
2025-08-19
Stroke remains one of the leading causes of long-term disability worldwide, affecting millions each year. Among its most debilitating consequences is gait impairment, which affects over 80% of stroke survivors. Impaired walking not only reduces independence but also limits participation in daily and social activities, significantly diminishing the quality of life. While some patients regain partial ambulatory function, walking speed and coordination often remain impaired. Alarmingly, up to 22% of survivors never regain the ability to walk and are ...
Pusan National University unveils 3D-printed brain vessels to transform atherosclerosis research
2025-08-19
Cerebrovascular diseases such as atherosclerosis and stroke remain a major cause of morbidity and mortality worldwide. A common feature of these diseases is vascular stenosis, i.e., the narrowing of blood vessels, which disrupts normal blood flow and contributes to chronic inflammation in the vessel wall. Endothelial cells lining the vasculature play a key role in sensing shear stress from blood flow and responding to disturbed hemodynamics by expressing pro-inflammatory molecules. However, studying this phenomenon in vivo is challenging due to the complexity ...
Sensing sour: How SNAP25 powers taste signals and keeps sensory cells alive
2025-08-19
The tongue contains numerous taste buds—tiny sensory organs responsible for detecting taste. Taste buds consist of specialized cells that translate chemical stimuli into neural signals. Among them, type II cells, which respond to sweet, umami, and bitter stimuli, utilize channel-based signal transmission. In contrast, type III cells are believed to mediate sour signals via synaptic vesicle release. While the signaling mechanisms of type II cells are well-characterized, the process of vesicular synaptic transmission in type III cells is poorly understood.
Synaptic signal transmission relies on the SNARE complex, ...
