Light Pollution Disrupts Mosquitoes’ Diapause, Extending Biting Season and West Nile Virus Risk, Study Shows
A recent study by researchers at Ohio State University has suggested that light pollution in urban areas can have a significant effect on the behavior of mosquitoes that transmit West Nile virus. The study found that exposure to artificial light at night may disrupt the winter dormancy period, known as diapause, for female Northern house mosquitoes, causing them to delay their period of dormancy and remain active longer into the fall. This delay can potentially put humans and animals at greater risk of contracting West Nile virus, which is transmitted when infected mosquitoes feed on mammals.
The study also found that exposure to light pollution suppressed the accumulation of water-soluble carbohydrates, an essential food source for mosquitoes during the winter. Additionally, the accumulation of the sugar glycogen was reversed in mosquitoes exposed to artificial light at night. While this delay in diapause may have negative consequences for mammals in the short term, it could also reduce the survival rate of mosquitoes in the long term, as they may fail to fully engage in preparatory activities needed to survive the winter.
These findings have important implications for understanding the impact of human activity on the behavior of insects and their potential to transmit diseases. The researchers plan to carry out field studies to see if these lab findings hold true in the wild. As artificial light at night continues to be a growing concern in urban areas, these results suggest the need for further investigation into the effects of light pollution on insect behavior and the transmission of disease.

5 Habits to Boost Immunity During Cold and Flu Season
(Feature Impact) Your immune system is your strongest ally during cold and flu season, working hard to keep you healthy as you start hearing those telltale coughs and sneezes all around. Help your body do its job well by adopting a few simple habits that naturally support its ability to fight off germs or recover faster.
Talk to your healthcare provider for personalized advice then work on making these habits normal in your household.
Get Regular Exercise
Exercise is like a wonder drug that can improve nearly every aspect of health and wellness. Physical activity increases blood flow, reduces long-term inflammation, helps immune cells circulate through the body to guard against invaders and may even flush bacteria out of your lungs and airways. Plan to fit at least 150 minutes of moderate exercise into each week, like a bike ride, brisk walk, yoga class or on-demand video workout.
Eat Foods That Support Immune Health
To keep your immune system fueled, experts recommend eating a varied diet featuring plenty of fruits, vegetables, nuts, seeds, whole grains and healthy fats like olive oil. Consider adding fresh grapes to your diet to enjoy benefits from their naturally occurring plant compounds.
Protecting the body starts all the way down at the cellular level, and grapes contain powerful polyphenols that support the health and function of cells. Studies indicate certain compounds in grapes, like resveratrol and flavonoids, support immune system function as well as brain, skin, GI and heart health.
These little fruits are easy to add to your diet, whether you enjoy sweet, juicy Grapes from California by the handful or toss them in a blender to make this California Grape Wellness Juice recipe. Support multiple aspects of wellness with the drink’s powerful combination of fruits and vegetables, delivering a variety of immune-boosting vitamins, minerals and antioxidants.
Stay Hydrated
Drinking enough water helps clean your lymphatic system, which is responsible for producing special white blood cells that fight germs. It also keeps membranes in your nose and mouth moist, decreasing infection risk. If you struggle to drink enough, eating water-rich foods like grapes also helps you improve hydration.
Practice Good Germ Hygiene
To increase your odds of staying healthy during peak illness season, hearken back to the tried-and-true hygiene advice your parents might have tried to drill into your head as a kid. Regularly wash your hands with warm water and soap, avoid touching your face while out and about, keep your distance from symptomatic people and disinfect commonly used surfaces like doorknobs when someone in the house or office is sick.
Sleep More, Stress Less
Before you start feeling stressed that you aren’t getting enough sleep, rest assured there are easy changes you can make to support your well-being in both areas. Try switching up your nightly routine to be oriented less around screens and more around calming activities that actually help you wind down, like yoga, meditation or reading.

Child Health
Changing the Landscape of Childhood Cancer Survivorship
Childhood Cancer: hile “cancer” is a term no family wants to hear, especially when it comes to their children, there is reason for hope. Today, 85% of children diagnosed with cancer survive at least five years. Survival is only part of the journey, however.
Changing the Landscape of Childhood Cancer Survivorship
(Feature Impact) While “cancer” is a term no family wants to hear, especially when it comes to their children, there is reason for hope. Today, 85% of children diagnosed with cancer survive at least five years, according to the National Cancer Institute, up from 75% three decades ago.

“This progress is driven in large part by dedicated research,” Hyundai Hope on Wheels Board Member Kevin Reilly said. “Over the last 28 years, Hyundai Hope on Wheels has committed over $300 million in pediatric cancer research and program grants, awarding more than 1,600 grants to 210 medical institutions nationwide, impacting thousands of young lives each year.”
Survival is only part of the journey, however. Nearly half (46%) of U.S. adults believe a child ringing the hospital bell after cancer treatment means the child is cancer-free and their medical journey is largely over, according to a survey conducted by Atomik Research on behalf of Hyundai Hope on Wheels. For the children and families living through a diagnosis, the reality is far more complex.
“The reality is that healing continues long after treatment, which is why sustained investment in survivorship care is a priority for us,” said John Guastaferro, executive director of Hyundai Hope on Wheels.
Isabella Franco-Capps, 11, understands that journey firsthand. Diagnosed with B-cell acute lymphoblastic leukemia at age 5, her journey took two years before she could say she’s “a cancer survivor.”
“I was diagnosed with b-cell acute lymphoblastic leukemia,” she said. “This began my two-year-long journey of scans, pokes, chemotherapy and hospital stays. And now I’m a cancer survivor.”
Fellow Hyundai Hope on Wheels National Youth Ambassador, Jackson Trihn, 12, is using his voice to call for continued research and to bring hope to others.
“The role … is being able to share my story,” he said. “Not just to spread awareness but to spread hope to kids that need it. And awareness is so important because people don’t understand how hard pediatric cancer can be.”
Continued progress can help ensure more children ring the bell and receive the care and support they need long after they’ve had the opportunity to do so. To learn more about these efforts and how you can help, visit HyundaiHopeOnWheels.org.

(Feature Impact) Driven by rising rates of obesity, diabetes, high blood pressure and other risk factors,cardiovascular disease has surpassed cancer as the leading cause of death among Hispanic adults in the United States.
Hispanic people represent nearly 1 in 5 of the U.S. population and are the nation’s largest ethnic minority group, yet many continue to face barriers to achieving heart health and accessing high-quality healthcare. A new scientific statement published in the American Heart Association’s flagship journal, “Circulation,” revealed how social, economic, cultural and environmental factors contribute to persistent disparities in cardiovascular health, calling for culturally tailored prevention strategies, equitable access to care and greater representation of Hispanic populations in cardiovascular research.
“Hispanic populations in the U.S. are incredibly diverse even within their own communities with differences in genetic ancestry, language, cultural traditions and social experiences that can significantly influence cardiovascular health,” said Johanna Contreras, M.D., M.Sc., FAHA, director of the Division of Heart Failure and medical director of the Hispanic Heart Center within the Mount Sinai Health System. “Yet Hispanic people remain underrepresented overall in the research that guides prevention and treatment strategies… Without better representation and more detailed data, we risk overlooking important differences that can help us improve care and save lives.”
Hispanic Cardiovascular Health by the Numbers
Cardiovascular risk factors – obesity (nearly 46%), type 2 diabetes (15.5%) and high blood pressure (approximately 44%) – are prevalent among Hispanic adults and often emerge at younger ages and occur more frequently among Hispanic adults compared with white adults.
According to the report, only about 1 in 5 Hispanic adults achieves ideal cardiovascular health as defined by the American Heart Association’s original Life’s Simple 7 metrics. Updated analyses using the Life’s Essential 8 framework demonstrated persistent disparities for heart and brain health, as well as suboptimal dietary quality, sleep patterns and levels of physical activity.
Social and Economic Barriers Matter
Biology alone does not explain cardiovascular health disparities. The environments where people live, work and age, along with social and economic challenges, impact heart health. In fact, approximately 17% of Hispanics live below the federal poverty threshold, compared with 8.2% of white adults.
“Many Hispanic adults face obstacles that extend far beyond the doctor’s office,” Contreras said. “Limited health insurance coverage, language differences, food insecurity, environmental exposures and concerns related to immigration status can make it more difficult to prevent disease, manage chronic conditions and receive timely treatment.”
Contreras emphasized the cultural values and practices of Hispanic people also influence how they perceive their health and healthcare options.
“Family plays a central role in many Hispanic communities and can be an extraordinary source of strength, support and resilience,” Contreras said. “At the same time, family members are often called upon to translate medical information, navigate health systems and help make healthcare decisions for loved ones. Those responsibilities can shape how health information is understood and acted upon.”
An Action Plan for Improving Hispanic Health
There are practical opportunities to achieve equitable cardiovascular health and reduce disparities through community engagement, culturally responsive care, inclusive research and policies that address the underlying drivers of health.
“Reducing cardiovascular disease among Hispanic populations demands action at every level,” Contreras said, “from improving access to culturally responsive care and expanding research participation to addressing the social and environmental conditions that shape health.”
By addressing both medical risk factors and the social conditions that shape health, experts believe there is an important opportunity to reduce disparities and help more people live longer, healthier lives. Learn more at Heart.org.
