The tiny ice inhabitants darken the glacier’s surface, which can accelerate its melting. Glaciers are massive bodies of white ice that reflect a significant amount of sunlight. However, in areas where the snow has melted and the bare ice is exposed, dark patches often appear. These dark areas are caused by microscopic algae that grow […]

Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams could one day carry information or measure air turbulence, but researchers discovered that real-world conditions like turbulent air can distort them more than expected. To combat this, […]

Despite its Earth-like rivers and lakes of liquid methane, Saturn’s moon Titan seems oddly lacking in river deltas — geological formations that are typically rich in historical clues. Using data from the Cassini spacecraft and simulations based on Earth’s landscapes, researchers expected to find deltas at the mouths of Titan’s rivers. Instead, they found almost […]

A new kind of microscope called ELVIS is heading to the International Space Station to change how we study life in space. By creating stunning 3D holograms of cells, it allows scientists to observe how organisms adapt to microgravity and other extreme conditions. This could help us understand whether life can exist on icy moons […]

Scientists have found a clever way to double the efficiency of thermoelectric materials — those that convert heat into electricity — by mixing two substances with contrasting mechanical properties but similar electronic traits. The result is a hybrid that blocks heat at microscopic interfaces while allowing electricity to flow freely, bringing us closer to cheaper, […]
