Best of 2025: Five must-read articles from the Science Section

Hesandi Ravisinghe in Galle, Sri Lanka

16-year-old Hesandi picks her favourite articles from the Science section this year

The hot new topic is science in 2025 has been AI (Artificial Intelligence), with many arguing over its potential benefits and possible dangers – we’ve published at least a dozen articles on the subject. The topic of global warming and climate change is becoming more pressing too, as shown by the UN’s latest climate conference, COP30, which took place in Brazil just a few weeks ago.

The Science section has covered plenty of other areas too, from mental health challenges to ground-breaking drugs. Our writers have brought new and interesting perspectives and thoughts to Harbingers’ Magazine through their articles.

As the Science Editor, I’ve compiled five articles that I think are interesting, informative and very relevant to our youthful audience. Think of this as a quick tour of what we’ve covered this year.

The political struggle to address climate change-related issues has remained largely unchanged over the years. Klara Hammudeh takes a unique approach in exploring this topic through the play Kyoto – which depicts the negotiations leading up to the landmark 1997 UN treaty known as the Kyoto Protocol – and explains how its themes remain relevant to this day. This piece has a gripping concept that is new and refreshing.

Sofia Vorobei relates how social media negatively impacts our self-esteem and body image through her own experience with an eating disorder. This article brings up a struggle many young people go through, and explains how society, via social media, can often push us towards unrealistic and potentially harmful standards.

Samantha de Mesa explains the importance of sex education in her homeland, the Philippines, and explains how cultural beliefs surrounding the subject make it challenging for schools. She also addresses the country’s growing HIV pandemic and why it’s crucial to reducing the stigma surrounding HIV, in order to create a society that is free of judgement – so people are able to receive the help they need.

AI deepfakes – digital versions of people’s identities – have been a cause for concern for a long time. Sofiia Didenko’s piece reveals how Denmark’s new legislation, designed to give people copyright over their own appearance and so protect them from deepfakes, could be an example to other European countries. The model prohibits sharing AI deepfakes without consent, and is expected to have a positive influence on the rest of EU.

In this piece, I examine the science behind the beautiful natural phenomenon that is the mass bloom of Strobilanthes flowers, in Horton Plains National Park in Sri Lanka. This is a very rare event, occurring only once every 12 years. I explain the importance of the plant, known locally as nelu, its role in the ecosystem and why protecting it is crucial to balance the natural processes of nature.

Our writers and contributors did a fantastic job in the Science section, covering a wide range of topics from all over the world. Choosing my favourites was no easy task, as each and every article is worth reading and there is so much to learn from each one. We hope to publish many more science-related articles in the upcoming year – until then, have a wonderful holiday!
