A study found that adolescents whose parents engage in risky behaviors, such as smoking and heavy drinking, are more likely to be sexually active and participate in other problem behaviors. Conversely, high levels of parental supervision are associated with reduced likelihoods of sexual activity.
Researchers discovered that bone marrow cells can form new blood vessels in newborns, contrary to previous belief that this process only occurs before birth. The study also found that VEGF accelerates the formation of new blood vessels, with implications for tumor biology and congenital disorders.
A recent study by researchers Jennifer Gerlach and Dorothy Espelage found that exercise may not have a positive impact on the mental health of women with eating disorders.

Researchers discover helicity, a twisted structure within the Sun's magnetic field, causing coronal mass ejections (CMEs) that can affect modern technology and the northern lights. Understanding CMEs is crucial for predicting space weather.
Researchers found that a combination of these risk factors can increase violent behavior more than tenfold. Without any of these factors, those with severe mental illness were no more likely to engage in violent behaviors.
A study of 42 female organ recipients found mostly successful pregnancies without birth defects, but lung transplant patients faced higher risks. Complications and health issues were more common in mothers with pre-existing health problems during pregnancy.
Researchers discovered a drug that protects fertility and offspring in mice after radiation exposure. S1P-based pharmacological approach preserves ovarian function without propagating genetic damage.
