Navigating Urban Flood Risk: Assessment, Modelling, and Management
In the face of evolving climate dynamics, urban flooding is emerging as a major concern that calls for urgent action and demands prioritization in research initiatives. Since 1980, over 4588 flood disasters have occurred in 172 countries, causing the loss of over 250,000 people’s lives (Dąbrowska, et al., 2023). In nature, fluctuations in water levels…

Sun’s Out, Sunscreen’s Out
Sunscreen contains compounds that contribute to marine ecosystem degradation. It is for this reason that in 2021, Hawaii banned sunscreens containing the chemicals oxybenzone (BP-3) and octinoxate (Suh, et al., 2020). These two chemicals are damaging to coral reefs, which are already compromised due to anthropogenic factors, like pollution. This discussion is centred around BP-3…

In the grandness of space, a recent study with the eROSITA X-ray telescope has revealed new insights into how our universe functions by exploring the fabric of space and time. The extended Roentgen Survey with an Imaging Telescope Array (eROSITA) X-ray, is essentially a space-based observatory designed to survey the sky in X-rays (Eppinga, 2023).…

Seeing Through Your Fingers
Close your eyes and listen. Listen to the noises you hear, the scents that you smell, and the feeling of skin surfacing your body. Why is it that we only notice this once our eyes are closed? This is the concept behind neuroplasticity. Neuroplasticity is the ability for the brain to reorganize itself by creating…
