How safe are our timber-frame buildings?

Why do scientists sometimes call microalgae "the green gold"? Well, in addition to biofuels and astronaut food, you could use them to make sunscreen. These tiny algae contain substances that protect them from sunlight, which can also come in handy for humans. Unfortunately, they don't naturally produce enough of those substances. Elke Vereecke researches how to grow microalgae packed with those sunlight-protecting components.

Did you know that every two minutes, enough ice melts on Earth to fill around 400 Olympic swimming pools with its meltwater? "The urgency is real – glaciers worldwide are disappearing at an alarming rate. In various corners of the globe, millions rely on these majestic glaciers for their drinking water and agricultural needs." Dive into the eye-opening short trip with glaciologist Lander Van Tricht as he takes you on a glacier expedition in Kyrgyzstan.

Sujith Reddy is working on perovskites, a promising new solar cell technology that captures more sunlight and costs less than conventional solar cells. Sounds great, right! But there's a catch: these perovskite solar cells ironically tend to break down when exposed to ... light. Sujith wants to uncover the mechanisms behind this degradation in order to improve perovskites and to use them on a larger scale.
