Naturally shed baby teeth may hold the key to understanding how early-life exposures shape
"Primary teeth provide a unique timeline of early life," Dr. Synnøve Stokke Jensen at the University of Bergen says. "They preserve information from pregnancy and childhood that cannot be captured retrospectively in other ways. This allows us to investigate environmental exposure
Estrogen-based hormone therapies could protect brain health in older women
Researchers from the University of Kansas have shown a link between reproductive hormone exposure throughout life and brain health in 459 women ages 65 to 80. They discovered older women who had used hormonal birth control in young adulthood were more likely to have larger volume
Exposure to bright evening light linked to higher risk of age-related eye disease
Every sunrise and sunset sends the body a signal, keeping the circadian clock running on a roughly 24-hour cycle. This clock evolved so organisms could adapt to Earth's daily rotation, syncing their biology to the pattern of day and night. Artificial lighting has freed human soci

Long-term hepatitis control efforts dramatically reduce HBV and HCV burden in Japan
Hepatitis B (HBV) and hepatitis C (HCV) are viral infections that can lead to health conditions such as cirrhosis, cancer and death if unmanaged. HBV can be transmitted through sexual contact, blood exposure and mother-to-child transmission, while HCV is primarily transmitted thr
Early pregnancy air pollution exposure linked to persistent depressive symptoms
Exposure to common air pollutants during early pregnancy may increase the likelihood of persistent depressive symptoms throughout pregnancy, according to a new study led by Tracy Bastain and co-authored by Carrie Breton, who recently joined Bursky School of Public Health at Washi

The most useful thing about a new HIV prevention guide may be a question it never asks: Why do you want to know about pre-exposure prophylaxis, or PrEP? In a pilot study at three clinics, a two-page decision aid helped people choose between a daily pill, long used to prevent HIV,
Extreme temperatures increase emergency department visits among people with dementia, stud
Exposure to extreme heat and cold is associated with an increased risk of emergency department (ED) visits among people living with dementia, according to preliminary research presented at the European Academy of Neurology (EAN) Congress 2026. The findings provide new evidence th

Going from the lab into the fire to study cancer risk in wildland firefighters
Cancer researchers at the Sylvester Firefighter Cancer Initiative (SFCI), part of the University of Miami Miller School of Medicine, took a rare step to better understand the cancer risks wildland firefighters face: They became wildland firefighters themselves. The firsthand expe

Invisible threads: How our environment quietly shapes disease
From the air we breathe to the food we eat, we are constantly exposed to thousands of chemicals—yet how these exposures affect our health has remained surprisingly difficult to understand. A new study led by researchers at the CeMM Research Center for Molecular Medicine of the Au
Early dog exposure may protect babies from infections through home microbes
Children who have been in contact with dogs in early childhood are, on average, healthier and require fewer courses of antibiotics than children without such contact. The protective association is explained, at least in part, by the spread of dog-associated microbes in the home.
Violence may bring menopause up to 20 months earlier, review suggests
A study by the Department of Obstetrics and Gynaecology at the University of Granada has revealed that exposure to violence against women throughout life has lasting effects that extend into middle age. The research, published in Maturitas, shows that women who have experienced v
