Q&A: Why clouds are still ‘one of the biggest uncertainties’ in climate change

Clouds are important from a climate point of view for how they reflect and absorb sunlight, according to Professor Pier Siebesma, an atmospheric physicist. Image credit - Pier Siebesma

They might be beautiful at times, but clouds are still one of the biggest sources of uncertainty in understanding how the climate will change due to global warming, explains Professor Pier Siebesma, an atmospheric physicist at Delft University of Technology (TU Delft) in the Netherlands. Enormous field studies of clouds and high-resolution computer simulations are … Read more

Future wearable electronic clothing could be charged by our own body heat

by Sarah Wild Thanks to rapid computing developments in the last decade and the miniaturisation of electronic components, people can, for example, track their movements and monitor their health in real time by wearing tiny computers. Researchers are now looking at how best to power these devices by turning to the user’s own body heat and working … Read more

Lightweight, bendy, cheaper – the promise of organic solar panels

Today’s silicon solar panels are an industry standard, but these rigid, heavy blocks may be shunted aside by plastic rivals – lightweight, flexible solar panels that could be printed and stuck onto buildings or placed in windows or cars, turning light into electricity in locations inaccessible to their heavier cousins. The standard solar panels we … Read more
