WASHINGTON, Aug. 19, 2025 — Our sense of smell is more important than we often realize. It helps us enjoy food, detect danger like smoke or gas leaks, and even affects memory and emotion. Many people — especially after COVID-19, aging, or brain injury — suffer from a loss of smell. However, there are very few effective treatments, and those that exist often use strong scents or medicines that cause discomfort in patients. In a study published this week in APL Bioengineering, by AIP Publishing, researchers ...

WASHINGTON, Aug. 19, 2025 — One of the world’s most popular sports, badminton is played by around 220 million people across the globe. As with other racket sports, a well-executed serve can establish a consequential advantage at the start of a rally. The “spin serve” was introduced by a Danish player at the Polish Open 2023 badminton tournament. The technique adds pre-spin before the racket touches the shuttlecock, whose natural spin is typically determined by its feathers’ inclination ...

Heat waves — prolonged periods of abnormally hot weather — influence egg prices, energy bills and even public transit. And they’re becoming more common as temperatures increase. In a new study, UIC researchers report that heat waves across Africa are hotter, longer and more frequent today than 40 years ago, mainly due to increased greenhouse gas and black carbon emissions from burning fossil fuels. Understanding heat waves’ origins and effects can help African countries predict them and ...

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 ...

Automated insulin delivery (AID) systems such as the UVA Health-developed artificial pancreas could help more type 1 diabetes patients if the devices become fully automated, according to a new review of the technology. Even as the artificial pancreas and other AID systems have helped millions of people with type 1 diabetes better manage their blood sugar and improve their overall health, there are still limitations to overcome, according to the review from University of Virginia Center for Diabetes Technology scientists and their colleagues. These limitations include: AID systems are not yet fully ...

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 ...

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 ...

PAUL (08/19/2025) — Researchers at the University of Minnesota Twin Cities have made a groundbreaking discovery by observing and analyzing the first new type of plasma wave in Jupiter’s aurora. This research helps us understand “alien aurora” on other planets, which in turn teaches us more about how Earth’s magnetic field protects us from the sun’s harmful radiation.  The research is published in Physical Review Letters, a peer-reviewed, multidisciplinary, high-impact scientific journal. The observation is based on data from NASA’s Juno spacecraft, which made a historic low ...

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 ...

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 ...

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, ...
