This counterintuitive result highlights the complex relationship between antioxidants and exercise.
Children exposed to antiepileptic drugs in utero are at risk for motor development issues, language skills difficulties, and autistic traits. The study also found no increased risk of developmental delays in children born to mothers with epilepsy who did not use AEDs during pregnancy.
A study found that over three-quarters of imported bumblebee colonies tested carried parasites, posing a risk to native bees and honeybees. The researchers argue that producers must improve disease screening and regulatory authorities must strengthen measures to prevent the importation of parasite-carrying colonies.
A new study reveals significant variability in patient death rates following emergency surgical admissions in England. Hospitals with better resources tend to have higher survival rates, suggesting that quality of care is a key factor in mortality rates.
