A study of 177 teenagers found that most were open to receiving texts about health, but preferred tone and content over phrases like 'you should' or 'always.' Interactive quizzes, simple recipes, and links to websites were well-received. The study suggests text messaging as a supplement to in-person nutrition education for teens.
Researchers at Mayo Clinic identified an association between the naturally occurring enzyme Kallikrein 6 and malignant brain tumors. Higher levels of KLK6 were associated with shorter patient survival rates, but blocking its receptors made tumor cells more susceptible to treatment.
Research found that over 75% of people with the ABCC11 gene variant don't produce under-arm odour but use deodorant. However, only a quarter of these individuals realize they don't produce odour and don't use deodorant, while three quarters do. The study suggests that socio-cultural norms play a significant role in deodorant usage.
