Scientists have highlighted advances in controlling brain neurons using light, detecting space-originating neutrinos and studying the three-dimensional structures of molecules at a science lecture in Chattogram.
The sixth edition of the Nobel Science Lecture, organised by Drishti Chattogram, was held at the Theatre Institute auditorium on Friday (13 November), attracting more than 300 students, young researchers and science enthusiasts.
Sponsored by the Chattogram District Council, the event also featured a quiz competition and poster exhibition.
At the panel discussion, Independence Award-winning scientist Professor Dr Hasina Khan discussed medical science, Chittagong University Professor Dr AKM Rezaur Rahman spoke on physics, and Cuet faculty member Dr Ratul Kumar Shil presented developments in chemistry.
Hasina Khan said Carl Deisseroth, Peter Hegemann and Georg Nagel developed optogenetics, a technique that uses light to activate or deactivate specific neurons. It offers new opportunities to study memory, emotions and behaviour and could help develop treatments for Parkinson’s, epilepsy and depression.
Rezaur Rahman said Francis Halzen was recognised for his contribution to detecting neutrinos using a specialised method involving South Pole ice. The research could help scientists investigate cosmic phenomena, including black holes and stellar explosions.
Shil said research into the three-dimensional structures of molecules could lead to safer, more effective medicines and new agricultural chemicals.
Chief guest Mohammad Mahbuber Rahman Shamim, administrator of the Chattogram District Council, stressed the importance of fostering scientific reasoning, curiosity and research interests among young people.
Former Drishti Chattogram president Saif Chowdhury said research and innovation could help Bangladeshi youth contribute to global scientific discoveries. Chittagong University Professor Dr Adnan Mannan also highlighted the importance of encouraging young people to pursue research and apply science for human welfare.
At the concluding session, Shohojpath Fulki won the school-level quiz, while Haji Muhammad Mohsin College won the college-level competition. Poster exhibition winners included teams from Chittagong University, Cuet and Chittagong Medical College.
Eleven science and education-based organisations joined as co-organisers. GR Metallic was also a sponsor, while Bigyan Chinta and the Bangladesh Science Popularization Association were the magazine and knowledge partners, respectively.
