Using gas stoves at home significantly increases cancer risk

A new study in the Journal of Hazardous Materials modeled benzene emissions from the top 5% of gas stoves in U.S. homes, finding elevated cancer risks, especially for children, in poorly ventilated spaces. Using validated simulations, the researchers estimated up to 69 additional leukemia cases annually under high-use, unventilated scenarios.

Vitamin supplement slows glaucoma progression in animal studies

A vitamin supplement that improves metabolism in the eye appears to slow down damage to the optic nerve in glaucoma.

Eating avocado in pregnancy cuts infant food allergy risk by nearly half

Pregnant women who ate avocado were significantly less likely to have children with food allergies at 12 months of age. The association held even after adjusting for maternal diet quality, lifestyle, and perinatal factors in a large Finnish cohort.

HIV drugs found to significantly reduce Alzheimer's risk in new study

UVA Health scientists are calling for clinical trials testing the potential of HIV drugs called NRTIs to prevent Alzheimer's disease after discovering that patients taking the drugs are substantially less likely to develop the memory-robbing condition.

High intake of ultra processed foods linked to early signs of Parkinson's

People who eat more ultra processed foods like cold breakfast cereal, cookies and hot dogs are more likely to have early signs of Parkinson's disease when compared to those who eat very few ultra processed foods, according to a study published in the May 7, 2025, online in Neurology, the medical journal of the American Academy of Neurology.

Study links sleep apnea to damage in brain areas critical for memory

Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain's small blood vessels, according to a study published May 7, 2025, online in Neurology, the medical journal of the American Academy of Neurology.

Understanding the psychological toll of asthma or allergies

People who have struggled with asthma or allergies for years understand the psychological toll of these conditions.

AI identifies brain cell types through electrical signatures

A decades-old challenge in neuroscience has been solved by harnessing artificial intelligence (AI) to identify the electrical signatures of different types of brain cells for the first time, as part of a study in mice led by researchers from UCL.

How urine caffeine levels may help detect diabetic eye damage early

Researchers found that higher urinary levels of caffeine and specific metabolites, especially in men, were significantly associated with diabetic retinopathy risk. The cross-sectional study used NHANES 2009–2014 data and highlights potential biomarkers for early detection in diabetic populations.

AI model significantly improves detection and treatment of delirium

An artificial intelligence (AI) model improved outcomes in hospitalized patients by quadrupling the rate of detection and treatment of delirium.

Low blood sugar linked to retinal damage in diabetic eye disease

In a new National Institutes of Health-funded study led by scientists at the Wilmer Eye Institute, Johns Hopkins Medicine researchers say they have determined that low blood sugar, or hypoglycemia, may promote a breakdown of the blood-retinal barrier, an important boundary that regulates the flow of nutrients, waste and water in and out of the retina.

Study reveals opposing roles of two proteins in Huntington's disease

A decade ago, University at Buffalo researchers shed some light on an enduring neuroscience mystery: How exactly does a mutated huntingtin protein (HTT) cause Huntington's disease?

Caffeine increases brain complexity during sleep and shifts it toward a critical state

Caffeine shifts brain activity during sleep by increasing EEG complexity and reducing long-range temporal correlations, particularly in non-REM (NREM) sleep. These changes reflect a movement toward a “critical regime” of neural processing, more pronounced in younger adults.

NR2F1 promotes cataract formation by activating STAT3 pathway

Cataracts are a prevalent ocular condition characterized by a progressive decline in vision, ultimately leading to blindness.

Fast action from bystanders can improve cardiac arrest survival. Many don’t know what to do.

When a woman collapsed on an escalator at the Buffalo, New York, airport last June, Phil Clough knew what to do. He and another bystander put her flat on her back and checked her pulse (faint) and her breathing (shallow and erratic).

Dopamine circuit helps the brain unlearn fear

Dangers come but dangers also go and when they do, the brain has an "all-clear" signal that teaches it to extinguish its fear.

Why your heart works harder at night after a few drinks, according to new research

Researchers at Ludwig Maximilian University of Munich found that moderate alcohol consumption transiently raises nocturnal resting heart rate without altering objective sleep stages. However, it worsens subjective sleep quality, highlighting subtle cardiovascular stress even at low alcohol doses.
