Uncover reality

A new chapter in nuclear energy has begun in China, where construction has officially started on what is being described as the world's first commercial hybrid nuclear power plant. Located at the Xuwei site in Jiangsu province, the ambitious project combines two different types of nuclear reactors to produce both electricity and high-temperature industrial steam. Unlike traditional nuclear power stations, which mainly generate electricity for homes and businesses, this facility has a different purpose. It is designed to supply enormous quantities of heat directly to nearby chemical factories and petrochemical refineries while also sending surplus electricity to the regional power grid. The project could become an important example of how nuclear energy can help reduce pollution in industries that are traditionally difficult to decarbonize. A Different Way to Use Nuclear Energy Nuclear power plants have traditionally been designed to generate electricity. However, many industrial fa...

Imagine a fish that can swim forward, reverse direction, move vertically, and remain almost perfectly still in the water without relying on its tail fin. It might sound like something from science fiction, but this remarkable ability belongs to a real aquatic animal called the black ghost knifefish (Apteronotus albifrons). Unlike most fish, which primarily use their tails to move through water, the black ghost knifefish relies on an unusually long, flexible fin running along the underside of its body. This ribbon-like structure allows it to perform incredibly precise movements, making it one of the most interesting examples of specialized swimming in nature. A new study led by Eric Youngerman and his research team has investigated how this unusual fin works. By examining the movements of the entire fin and the bending of individual fin rays, the researchers discovered how the fish controls its movement in different directions. A Fish With an Unusual Swimming System Most fish swim by mo...

Imagine traveling thousands of kilometres across a vast ocean without roads, signs, or GPS. Now imagine being able to recognize specific locations simply by sensing Earth's invisible magnetic field. This may sound like science fiction, but loggerhead sea turtles appear to have developed exactly this remarkable ability. In a fascinating discovery, researchers have found that loggerhead sea turtles can learn the magnetic signatures of particular geographical locations and use this information to recognize places where they have previously found food. The findings provide new insights into how migratory animals navigate across enormous distances and reveal that sea turtles may use two different biological mechanisms to understand Earth's magnetic field. How Do Sea Turtles Navigate Across the Ocean? Every year, sea turtles undertake incredible journeys through the world's oceans. Some travel thousands of kilometres between feeding grounds, breeding areas, and nesting beaches. D...

Imagine watching a planet orbiting a distant star for several years, only to see it suddenly disappear. No explosion, no collision, and no sign that it has been destroyed. This sounds like something from a science-fiction movie, but astronomers have discovered exactly this kind of mystery in a distant planetary system. An international team of astronomers led by researchers at the University of California, Los Angeles (UCLA), has discovered what they describe as the first known "disappearing planet." Located approximately 1,000 light-years from Earth, the planet, called TOI-2535 b , has not actually disappeared. Instead, its orbit is changing so dramatically that it has moved out of the viewing position needed for astronomers to detect it. The discovery provides a rare opportunity to understand how planets interact with one another and how unusual planetary systems develop over time. Meet TOI-2535 b: A Planet That Orbits Its Star Extremely Fast TOI-2535 b belongs to a categor...

How does a bird of prey track a moving target while flying at high speed? Scientists have developed a remarkable camera system that offers a bird's-eye view of the answer—literally. Birds of prey are highly skilled hunters. They can follow moving targets, adjust their flight paths and capture prey while flying through complicated natural environments. Although their hunting abilities have fascinated scientists for years, understanding exactly how these birds see, move their heads and track prey during flight has been extremely difficult. Now, researchers led by Kay-Michael Voit have developed an innovative camera system that allows scientists to observe these behaviors in extraordinary detail. By attaching a lightweight, wireless, 360-degree camera system to the head of a Harris's hawk, the team was able to reconstruct the bird's movements, visual surroundings and interactions with moving targets during real aerial hunting. The research provides a new way to study how birds...

Future spacecraft may explore asteroids by hopping across their surfaces rather than relying on traditional landing systems. But a new study reveals that the distance these robotic explorers can travel depends heavily on the tiny particles beneath them. Exploring an asteroid is far more complicated than simply landing a spacecraft on its surface. Unlike Earth, asteroids have extremely weak gravity, irregular shapes, and surfaces covered with loose rocks, gravel, dust, and other materials. These conditions make it difficult for a lander to move safely from one location to another. Previous space missions have shown that small Solar System bodies have surprisingly diverse landscapes. Their surfaces can contain large boulders, rocky slopes, fine dust, and uneven terrain. This creates a major challenge for spacecraft designed to conduct scientific experiments at multiple locations. To overcome this problem, scientists are investigating an unusual method of transportation: hopping robots th...

In the early Universe, when galaxies were still taking shape, some black holes had already grown to extraordinary sizes. These cosmic giants, weighing billions of times more than our Sun, powered some of the brightest objects ever observed: quasars. But how did these enormous black holes grow so quickly, and what connected their growth to the evolution of the galaxies surrounding them? A major scientific study led by astrophysicist Tiziana Di Matteo and her team offers an explanation. Their computer simulations reveal that violent collisions between galaxies could play a crucial role in creating supermassive black holes, triggering powerful quasars, and eventually stopping the formation of new stars. The findings also help explain a long-standing mystery in astronomy: why the mass of a supermassive black hole is closely connected to the properties of the galaxy at its centre. What Are Supermassive Black Holes and Quasars? Supermassive black holes are enormous objects found at the centr...
