1. Climate Refugees

As global temperatures rise and extreme weather events become more frequent, millions of people are being forced to abandon their homes and communities. While international law provides some protection to those fleeing persecution or war, it currently offers no formal legal status to those displaced by climate-related disasters — often called climate refugees. Countries in the Pacific Islands, Bangladesh, and sub-Saharan Africa are among the most vulnerable, facing the prospect of losing significant portions of their habitable land to sea-level rise and desertification. The absence of an internationally recognised framework for climate refugees creates serious gaps in protection and leaves the world’s most vulnerable populations with few legal recourses when their livelihoods and lands are destroyed by environmental change.

2. Sleep Science

Sleep was long regarded as a passive state of inactivity, but decades of research have revealed it to be an active and essential biological process that performs critical functions for both the brain and body. During sleep, the brain consolidates memories by replaying neural patterns associated with the day’s experiences and transferring information from short-term to long-term storage. Simultaneously, the glymphatic system — the brain’s waste clearance mechanism — removes toxic metabolic byproducts, including proteins associated with Alzheimer’s disease. In the body, hormones essential for growth, immunity, and tissue repair are released. Sleep deprivation, even in the short term, impairs cognitive function, increases inflammatory markers, elevates stress hormones, and significantly raises the risk of accidents. Despite widespread awareness of these facts, modern societies increasingly treat sleep as a luxury rather than a biological necessity.

3. Digital Currencies

Central bank digital currencies — digital forms of a nation’s official currency issued and regulated by its central bank — are being developed or piloted by more than 100 countries worldwide. Proponents argue that CBDCs could reduce transaction costs, improve financial inclusion by providing banking access to unbanked populations, and give central banks more precise tools for implementing monetary policy. However, critics raise concerns about privacy, since CBDC transactions could be traceable by governments, and about financial stability, since easy conversion from bank deposits to CBDCs could increase the risk of bank runs during periods of financial stress. The Bahamas launched the world’s first CBDC in 2020, and China’s digital yuan is among the most advanced large-scale pilots, but the design choices made by different countries will have profound implications for the global financial system.
