Fireworks may dazzle crowds with their bright colors and loud explosions, but new research shows their effects last long after the show is over. Three recent studies published in the journal of the American Chemical Society (ACS) examined what fireworks leave behind, from discarded debris and airborne particles to compounds released into the atmosphere. Together, these findings provide a clearer picture of how fireworks can impact air quality, water chemistry, and potentially both human health and the environment. Firecracker fragments can change water chemistry Once fireworks burn out, they leave behind more than just ash. Spent firecrackers scatter residues that…
A recent study from the University of Massachusetts Amherst suggests that using alcohol to cope with stress in early adulthood can have lasting effects on the brain that may persist even after years of sobriety. The study found that these changes begin to surface by midlife, making people less mentally flexible and more likely to return to alcohol during stressful times, and contributing to the pattern of cognitive decline associated with dementia and Alzheimer’s disease. Published in a magazine Alcohol clinical and experimental researchthe findings shed new light on how alcohol and stress work together to reshape brain circuits. Researchers…
Researchers have developed an artificial intelligence model that can track a person’s sleep stages using just three simple body measurements. The system analyzes your heart rate, blood oxygen levels, and abdominal breathing, charting your sleep down to the second without the need for invasive brainwave sensors. The findings, published in the Journal of Sleep Research, provide a path to making clinical sleep tracking more comfortable and accessible to patients at home. Rest is an active biological process characterized by distinct neurological and physical stages. When a person loses consciousness, they cycle through light sleep, deep sleep, and rapid eye movement…
Some people remain mentally alert despite the biological changes in their brains associated with Alzheimer’s disease. New research from the Netherlands Institute for Neuroscience suggests the answer may lie in how a rare group of brain cells called immature neurons respond to injury. The findings provide new insights into cognitive resilience, the brain’s ability to continue functioning despite illness. One of the biggest unanswered questions in Alzheimer’s disease research is why it affects people so differently. As Alzheimer’s disease progresses, many people develop memory loss and dementia, but others have little or no cognitive decline despite having the same underlying…
Imagine a mouse rapidly and intermittently sniffing the crumbs it finds while foraging. Now compare it to a human bending down and taking one deep breath to determine if a cantaloupe is ripe. A new study from Northwestern University has found that just like humans, mice can intentionally explore their environment with just one sniff. This is something scientists didn’t know before. Two new complementary studies from Northwestern University will be published together on July 3. scientific progressstudied olfaction from opposite sides and found that rodents and humans rely on the same basic neurophysiology to process odors: motor and rhythmic…
According to a study published in Psychology of Aesthetics, Creativity, and the Arts, professional visual artists have unique brain structures and activity patterns that appear to support the vivid mental imagery needed to create art. Most people can draw, paint, or sketch to some extent, but only a few develop the expertise necessary to become a professional artist. Scientists have long been interested in creativity, but little is known about how years of artistic training affect the brain. Previous research has identified brain networks involved in idea generation and refinement, but most research has focused on creativity in ordinary people…
Microplastic fears have dominated social media, news, and public conversations in recent years, and concerns about their impact on human health continue to grow. For runners, avoiding plastic is nearly impossible. Used in water bottles, energy gel packaging, shoes, apparel, and more. But how do microplastics actually affect us? And are we at higher risk for exposure to them? We spoke to experts about the science behind the presence of plastics in running shoes and their potential health effects. The dangers of microplastics Microplastics pose risks to both human health and the environment. Sharon Dodd A family physician in Richmond,…
An investigational targeted therapy designed to block one of the most common genetic drivers of pancreatic cancer has shown promising initial results when used in combination with standard first-line chemotherapy, according to research presented today at the ESMO Gastrointestinal Cancer Conference 2026. A phase I/II multicenter study led by researchers at Dana-Farber Cancer Institute in Boston evaluated zordonrasib in patients with metastatic pancreatic cancer whose tumors carry the KRAS G12D mutation. Initial findings showed high tumor shrinkage rates, significant reductions in cancer DNA detected in the bloodstream, and no unexpected safety concerns. Pancreatic cancer is one of the most deadly…
As carbon dioxide (CO2) emissions continue to rise, interest in geoengineering is growing as governments, researchers, and environmental advocacy groups seek ways to limit the worst effects of climate change. These large-scale climate interventions could affect rainfall, agriculture, and ecosystems around the world, and their potential benefits and risks are equally important. A new study by climate scientists at the University of California, Santa Barbara suggests that not all geoengineering strategies produce the same results. One of the proposed methods could significantly disrupt one of Earth’s most important climate cycles, while another appears to have little effect. The survey results…
