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.

Have you ever seen a timber-frame building? 🏠 You might be wondering how safe such a structure actually is. Well, the truth is that we don't quite know yet. Structural engineer Dries Byloos 👷 tells you why and how he is pushing for safer and taller timber-frame buildings.

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.

"Scientific information has to play a bigger role in the process of decision-making in policy." This is Ante Ivčević firm belief. In his research, he seeks to understand how policymakers make decisions and, more importantly, how we can get them to make these decisions based on scientific information. To investigate this, he researches science and policy regarding coastal areas in the Mediterranean basin.

Imagine that, instead of emitting harmful CO2 into the atmosphere, we could recycle it and use it to power your future laptop or smartphone. That's what Kevin Van Daele is researching. He is developing new catalysts to efficiently convert CO2 into formic acid, a valuable chemical that could one day power your future electronic devices. 

Did you know that the average lifespan of a wind turbine is 20 years? After that, unfortunately, wind turbines end up in landfills as they are built from thermosets, materials that can't be recycled (yet). "It's time to change that", says Marlies Thys. She is looking into making recyclable thermosets by using ... wood waste. 

Do you drink juice in the morning or enjoy a glass of wine to relax after a busy day? Did you know that in order to preserve its flavor and prevent bacterial growth, your favorite beverage has to go through several stages of processing? One is the filtration process, a very expensive production stage. To ensure you can enjoy your favorite drink at a low(er) price, Rishav Phukan is developing next-generation membranes, which will help the industry cut costs and produce in a more eco-friendly way.

Do you think we will be able to stop CO2 emissions by 2050? Because that's what we need to do to fight climate change. Worldwide, an estimated one million researchers are currently working on solutions for climate change. At Hasselt University, Talieh Rajabloo is mapping state-of-the-art climate research & technologies that can help energy-intensive industries such as the petrochemical and metal sectors reduce their CO2 emissions.

Have you ever heard of Boyan Slat? At the age of 18, he founded The Ocean Cleanup, an environmental enterprise developing and scaling technologies to rid the oceans of plastic. Environmental entrepreneurs such as Slat and their eco-innovations are the cornerstone of the transition to a more sustainable world. But how can we help them make a bigger impact? That's what Georgios Outsios is determined to find out.

Did you know that we can build bridges out of concrete with a 3D printer? Yet, this promising technology still faces challenges before it can reach its full potential and be widely used in construction. VUB researcher Yanjuan Chen explains what these challenges are and how she's working to help overcome them.

Hydrogen can play a key role in making our energy supply more sustainable. One problem though: hydrogen is highly flammable. So how do we store hydrogen safely? Joren Vanlaere is working on a solution to detect possible leaks at lightning speed.
