Around 354 million people in North America and Europe are likely to have been affected by fine particulate matter pollution from the 2023 Canadian wildfire season, a new study suggests.

Aqueous batteries, which use water-based solutions as an electrolyte, have been around since the 1860s. They are safe, efficient, and cheap. But many electrode materials do not perform well in aqueous electrolytes. Organic redox polymers are no different. To overcome this, a group of researchers has unveiled a new organic redox polymer that addresses its hydrophobicity.

To reduce plastic pollution and promote environmental sustainability, scholars from the Lingnan University School of Interdisciplinary Studies and their research team have developed a successful new eco-friendly bioplastic material. Unlike conventional plastics, it degrades naturally into harmless water and carbon dioxide in as little as 29 days under ambient conditions, and is a practical way to mitigate global plastic pollution. Their study, “Sustainable DNA-polysaccharide hydrogels as recyclable bioplastics”, was recently published in the respected journal Nature Communications.

On 19 August, World Humanitarian Day, Lingnan University announced the signing of an Agreement of Cooperation with the United Nations University (UNU) to establish the UNU Hub on Humanitarian Innovation and Technology at Lingnan University (UNU Hub at Lingnan University), making it the first higher education institution in Asia to set up a UNU Hub. The Hub is scheduled to open officially in October 2025 and will have an annual operating budget of over HK$8 million. Its Humanitarian Innovation and Technology Laboratory (HIT Lab) will spearhead research and design initiatives, education and training programmes, and international collaborations, and improve living conditions in developing countries and regions of the Global South by leveraging innovative and cutting-edge technologies. Scholarships will be awarded to encourage local youth to fulfil their ambitions through knowledge and innovation.

Lingnan University's science and innovation teams have achieved outstanding results at the 11th Silicon Valley International Invention Festival 2025 (SVIIF) in their first-ever participation. All 13 participating projects, covering areas such as artificial intelligence (AI), smart manufacturing, and intelligent transportation, won awards, including 8 gold and 5 silver medals. One of the projects, the AI-based Fencing Training and Assessment System, led by Prof Sam Kwong Tak-wu, Associate Vice-President (Strategic Research), also received a special award ⸺ Prize of the International Federation of Inventors’ Association (IFIA), making Lingnan the Hong Kong higher education institution that won the highest number of total awards and gold medals at this year’s festival.

The five-day 12th South-South Forum on Sustainability, hosted by the Chinese Institute of Hong Kong and co-organised by the Centre for Cultural Research and Development of Lingnan University, the Global University for Sustainability, the Centre for Film Studies and Cultural Studies of Peking University, and the Tsinghua Institute for Advanced Study in Humanities and Social Sciences of Tsinghua University, and coordinated locally by the Shangyou County People’s Government, is currently being held in Shangyou County, Ganzhou City, Jiangxi Province, China, the first time the Forum has taken place in Jiangxi.

A research team led by Distinguished Professor Hao Li at WPI-AIMR, Tohoku University has reported new findings on copper/cobalt-based catalysts that improve the efficiency of electrochemical nitrate reduction.

The Horizon Journal of Humanities and Social Sciences Research (JHSSR) proudly announces the release of its Special ASAIHL Edition – Volume 7(S), August 2025, themed “University’s Role in Advancing Climate Crisis Reduction.” This commemorative edition captures the pioneering spirit of Southeast Asian academia in addressing one of the 21st century’s most urgent global challenges—climate change. Curated from the prestigious 2024 ASAIHL Conference, hosted by Universitas Airlangga, Surabaya, Indonesia (Nov 19–22, 2024), this issue brings together a diverse body of scholarly contributions from researchers, policymakers, and educators across ASEAN and beyond. It marks a significant milestone in the academic community’s mission to inspire sustainable education, ethical leadership, and climate-responsive innovation.

Tohoku University researchers discovered some new principles that aid the electrochemical conversion of nitrate waste, an unwanted byproduct of modern day ammonia production. Their discovery will advance cleaner, more sustainable forms of ammonia production.

For many years, scientists have struggled to understand the mechanisms behind palladium/platinum catalysts for propylene electrooxidation, a sustainable means of producing valuable oxygen-containing organic compounds used in various industrial processes. Yet a research group has further clarified the matter in a recently published journal.

Tropical cyclones hundreds of kilometers away from the Philippines are often more responsible for heavy rainfall than those that hit the country directly during the annual “Habagat” or southwest monsoon season from July to September.

Households, cars, and factories generate heat, much of which goes to waste. Likewise, the increasing usage of solar panels means heat needs to be stored at large amounts for longer periods of time. Thus, thermal storage is critical for carbon-neurtrality. A collaboration between Tohoku University and Japan Atomic Energy Agency has developed nanosheets of layered manganese dioxide that can store heat even below 100°C.

A daily mismatch between temperature and humidity, observed in certain mountain and waterside regions, helps regulate atmospheric dryness. However, this protective effect may weaken under global warming.

With the rapid development of Artificial Intelligence (AI) and increasing environmental challenges, global catastrophic risks have gone beyond traditional natural disasters to raise controversial ethical issues. In view of this, the Hong Kong Catastrophic Risk Centre (HKCRC) of Lingnan University has introduced a new, free, online bilingual self-learning course on Ethics and Global Catastrophic Risks, taught by international authorities in philosophy and ethics. Designed to help people understand and cope with the complex landscape of global disaster risks through eight modules, the new programme, launched in late February this year, incorporates in-depth, real-life examples in AI, the environment, and the sciences, and has already attracted more than 8,000 participants from Mainland China, Hong Kong SAR, South Asia, the US, and Europe. It is now open to the public at no charge.
