Delayed puberty in boys raises risk of type 2 diabetes later in life, study shows

A large Israeli study found that boys who experience delayed puberty are significantly more likely to develop type 2 diabetes in early adulthood. This increased risk persists even after accounting for body weight, socio-economic status, and other confounding factors.

Researchers find 8,500 tonnes of antibiotics enter rivers every year

A global study led by McGill University estimates that 8,500 tonnes of antibiotics enter river systems annually, mostly from human use—even after wastewater treatment. The findings warn that chronic exposure poses risks to aquatic life and fuels antibiotic resistance, especially in regions with poor sanitation.

Maternal testosterone levels shape boys' activity and girls' strength by age 7

Boys born to mothers with PCOS or high third-trimester testosterone levels are less physically active at age 7, particularly on weekends. Girls exposed to high prenatal testosterone show reduced muscle strength but not lower activity levels.

Obesity in teens alters brain regions tied to memory and emotion

Adolescents with abdominal obesity have larger brain regions linked to memory and emotional control, potentially due to inflammation, according to a large MRI-based study. These brain changes, coupled with socioeconomic disadvantage, may impair cognitive and emotional development during adolescence.

Study reveals phthalate exposure harms early sexual development in children

Maternal exposure to phthalates during pregnancy is linked to shorter anogenital distance in 3-year-old boys, a marker of impaired sexual development. Girls showed similar outcomes from their own postnatal exposure, highlighting the lasting hormonal risks of environmental pollutants.

Researchers uncover why women handle body fat more efficiently

Women’s fat cells break down fat faster than men’s once activated, even though they require higher hormone levels to initiate the process. This may help explain why women are less prone to metabolic complications despite higher body fat.

Antibiotic use in infancy raises early puberty risk in girls, study finds

Girls exposed to antibiotics in the first three months of life are significantly more likely to enter puberty early, according to a large South Korean study. The risk increases with earlier exposure and a greater number of antibiotic classes, with no similar effect seen in boys.

Mothers' early pregnancy weight influences kids’ BMI into adolescence

Children born to mothers with higher BMI in early pregnancy have greater weight and BMI from birth through age 10, regardless of prenatal lifestyle interventions. Paternal BMI also plays a significant role in childhood obesity risk.

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.
