    Are Our Heritage Trees Actually Non-Native? with Dr. Shawn Lum

    Scattered across Singapore are 255 registered Heritage Trees—remarkable for their majesty, cultural value, and the histories these green landmarks are rooted in. While some are native, many aren’t. So how did our heritage trees end up here, and what makes them worth conserving? In this episode, tropical forest ecologist Dr. Shawn Lum walks us through the hidden world of our heritage trees, the work that goes into conserving them, and why they matter more than we might think. Episode Highlights • The meaning behind Heritage Tree status - how trees earn this prestigious designation through their botanical value and cultural significance • The extensive work that goes into conserving our natural heritage, from expert arborist inspections to lightning protection installation • The journey of Singapore's most common Heritage Tree species, the Rain Tree, from South America to Southeast Asia • Discovering century-old majestic trees in the Changi area that still stand as living witnesses to Singapore's changing landscape • How everyday citizens can contribute to forest conservation, from nominating potential Heritage Trees to participating in the One Million Trees movement Timestamps 00:00 Intro 00:59 Definition and Criteria for Heritage Trees 02:29 Nomination Process for Heritage Trees 04:27 Non-Native Species and Globalisation 07:34 Maintenance of Heritage Trees 10:44 Dr. Lum’s Favourite Heritage Trees 13:44 What You Can Do to Help Our Forests 15:14 Outro Guest Bio: Dr. Shawn Lum joined the NTU Asian School of the Environment in January 2016 after spending more than twenty years as a Lecturer at the National Institute of Education.

    Is Your Phone Making You More Kiasu? with Dr. Jean Liu

    According to a study by IMH, about 1 in 3 Singaporeans aged 15 - 65 are reported to have problematic amounts of smartphone usage in their daily lives. But what happens when we’re seeing our peers on their 5th couples trip to Japan on Instagram? Does it make us more “kiasu” about our own lives? Can our brains get so overloaded with digital content to the point of “brain rot?” What can we do to develop healthier relationships with our devices? Behavioural scientist Dr. Jean Liu shares her insights. Episode Highlights • How the “fear of missing out” (FOMO) drives problematic social media use—people who fear missing out are most vulnerable to excessive platform engagement and its negative effects, especially on social networking sites • Why the pop science concept of social media providing "dopamine hits" might be oversimplified and what neuroscience actually tells us about our brains on screens • The truth about "brain rot" and why consuming "mindless" content isn't necessarily harmful • How our phones are changing the way we remember and behave, from search-engine-oriented memory patterns to the psychological impact of "phubbing" (phone snubbing) • Practical strategies for digital wellness including the concept of "digital minimalism" that focuses on aligning device use with life goals rather than arbitrary screen time limits Timestamps 00:00 Intro 00:52 What is Kiasu? 01:39 FOMO and Social Media 03:06 Why is Social Media So Addictive? 04:51 Debunking the Dopamine Hit 06:42 Brain Rot 09:10 Effects of Screentime on the Brain 11:03 Healthier Relationships with Devices 13:25 Being Present for Others 14:37 Final Thoughts: Is Your Phone Making You More Kiasu? 15:12 Outro Guest Bio: Dr Jean Liu is a Director at the Centre for Evidence and Implementation, and adjunct Assistant Professor at Duke-NUS Graduate Medical School and the Yong Loo Lin School of Medicine. [Note: Since recording this episode, Dr. Jean Liu has been appointed as an Associate Professor of Psychology at Singapore Institute of Technology.] Her primary research area focuses on how digital devices impact our health and social relationships. To date, she has published >30 research papers on topics such as: how individuals use their phones during meals, how social media relates to mental health, how WhatsApp users transmit health messages, and whether following Taylor Swift predicts better mental health outcomes. In recognition of her expertise, Dr Liu has served as consultant to the World Health Organisation, assisting with the roll-out of a new mental health framework for the Western Pacific Region. She is also a Council Member for the Agency for Care Effectiveness, expert panelist for the Health Promotion Board, and board member for several non-profit organisations. Her research insights have been discussed in parliament, and she speaks frequently in the media. Read the full transcript and show notes at https://voiddeck.science.edu.sg/s2e3-psychology/
