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.

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.

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.

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.
