ABSTRACT
The sudden outbreak of COVID-19 in over 200 countries globally, brought serious effects on our daily lives. Traditional Chinese Medicine (TCM) in combination with regional characteristics has achieved remarkable results in China. Prunella vulgaris is one of the ingredients of commercially available canned Chinese herbal tea which demonstrated lifespan extending effect on Drosophila in our previous study, whereas it is unknown which ingredients contribute to it. This study used Drosophila as the model to explore whether Prunella vulgaris is the component taking effect on Drosophila longevity. Results showed that Prunella vulgaris can extend the lifespan of female flies by 10.42%, and improve their endurance under heat stress by 18.46%.

The outbreak of the COVID-19 has provided new challenges and also opportunities for the development of online education. Based on our experience from the online education after the outbreak of the COVID-19, this article proposes to introduce COVID-19 knowledge through film teaching methods. Films can stimulate students' interest in learning and improve the teaching efficiency of online education with its rich storylines, high-quality pictures, interesting, and entertaining nature. Teachers can carry out online teaching with the aid of films through four key steps: determining the key points of the teaching content, choosing matching films, setting up topic-related questions, and communicating and discussing after watching the film.

The outbreak of COVID-19 pandemic results in the suspension of universities' academic laboratory activities. This brought a difficult time for graduate students majored in molecular biology and their mentors, since the student's thesis progress relies on the data from wet experiments in the lab. Even facing the challenges during the pandemic, mentors could still play an active role. This COVID-19 crisis requires mentors to have more thinking, innovation, and sharing in guiding graduate students.
