Oxford Scientists Develop Ultra-Thin Solar Material That Can Power Everyday Objects

Researchers at the University of Oxford have created a groundbreaking "multi-junction" solar material so thin it can be printed onto everyday items like cars, smartphones, and backpacks. This innovative material, just one micron thick, boasts over 27% energy efficiency—surpassing traditional silicon-based solar panels by 5%. Though the findings are yet to be published, this advance could revolutionize how we harness solar energy in daily life.

Ever wondered why an iron anvil floats in mercury? It’s all about density and buoyancy! Mercury is incredibly dense—13.6 grams per cubic centimeter—while iron, though heavy, has a density of just 7.9 g/cm³. This density disparity means that when the anvil is placed in mercury, the upward buoyant force from the displaced mercury outweighs the iron's weight, allowing it to float effortlessly. So, in the world of fluids, mercury proves it can support even the heftiest of metals with a graceful buoyancy. Watch here

The slow stroll of Ecuador’s walking trees: nature’s real-life Ents. Deep in Ecuador's Sumaco Biosphere Reserve, a unique wonder unfolds as "walking" palm trees gradually shift their position across the forest floor. Unlike Tolkien's Ents, these trees move at a leisurely pace of two to three centimeters per day, driven by the growth of new roots. While scientists debate the phenomenon, palaeobiologist Peter Vrsansky swears he’s witnessed these remarkable trees in action.
