Uncover reality

Imagine a robot that can feel the pressure of a human touch, a wearable device that can monitor the body like a second layer of skin, or artificial limbs that can sense their surroundings just like humans do. This future is becoming closer as researchers develop advanced electronic skin technology that can bring human-like sensing abilities to machines. A team of Korean researchers has achieved a major breakthrough in flexible electronic skin technology by creating a new fabrication method that can produce large-area sensors directly where they are needed. The innovation could accelerate the commercialization of electronic skin for applications ranging from intelligent robots and wearable devices to healthcare systems and human-machine interaction technologies. The research was conducted by the Electronics and Telecommunications Research Institute (ETRI) in collaboration with Professor Ahn Jun Seong’s research team from the Department of Control and Instrumentation Engineering at Korea...

 For decades, designing advanced robots has been a challenge limited mostly to experienced engineers and researchers. Building a robot with legs, arms, or other moving parts requires deep knowledge of mechanics, electronics, programming, and manufacturing. Even a small mistake in the design process can make a robot unstable, inefficient, or impossible to build. But a new approach powered by artificial intelligence is changing the way robots are created. Researchers have developed a system that allows even non-experts to design personalized limbed robots using simple inputs like text descriptions or images. Instead of spending months designing every component manually, users can now generate robot designs within minutes to a few hours. The new framework , called Decomposition-Optimization-Assembling (DOA) , combines generative AI, engineering optimization, and modern 3D printing technology to automatically create functional robot designs. Turning Ideas Into Real Robots Imagine descr...

Beneath the surface of Earth’s oceans, rivers, and lakes lies a hidden world filled with incredible ecosystems, ancient shipwrecks, and unknown discoveries. Scientists and explorers have always searched for better ways to study these underwater environments, but traditional underwater robots often face a major challenge: they are powerful, but not gentle enough for delicate spaces. Coral reefs, underwater caves, and marine habitats are extremely fragile. A small collision from a heavy robotic vehicle can damage living organisms that may take decades or even centuries to recover. To explore these environments safely, researchers are developing a new generation of underwater robots that can move with flexibility, precision, and minimal disturbance. One such breakthrough is DRAGON 3D (Deformable Robot for Agile Guided Observation and Navigation in Three-Dimensions) — a soft, flexible underwater robot designed to move through complex underwater spaces while interacting safely with the en...

Deep inside our galaxy, something incredibly powerful happened millions of years ago. The center of the Milky Way experienced a huge burst of energy that sent massive shock waves racing through space. Today, the evidence of that ancient explosion can still be seen in the form of two enormous structures called the Fermi bubbles . Now, scientists have found new evidence that these giant bubbles are producing some of the most energetic particles in the universe. Using data from the IceCube Neutrino Observatory , researchers have detected signs of high-energy neutrinos coming from these mysterious structures. The discovery provides strong proof that the Fermi bubbles are acting like giant cosmic particle accelerators. The Giant Bubbles Above Our Galaxy The Milky Way is a huge spiral galaxy containing hundreds of billions of stars. At its center lies a supermassive black hole called Sagittarius A* , which has a mass millions of times greater than the Sun. Although the black hole is currentl...

The discovery of extremely massive black holes in the early universe has created one of the biggest mysteries in modern astronomy. Scientists have found black holes that existed when the universe was still very young, only a few hundred million years after the Big Bang. Some of these black holes are already millions or billions of times heavier than the Sun. The problem is simple: how did they grow so large so quickly? Traditional ideas suggest that black holes become massive by consuming gas, merging with other black holes, and growing over billions of years. But the early universe did not provide enough time for some of the observed supermassive black holes to reach their enormous sizes through these normal processes. This has led scientists to explore other possibilities. One interesting idea is that dark matter, the invisible substance that makes up most of the matter in the universe, may have helped early black holes grow. A recent study by Zhang and Mathews investigates whether d...

For decades, engineers have faced a major challenge in designing flying machines: creating aircraft that are both powerful and energy efficient. Traditional drones can take off vertically, hover in one place, and move with great agility, but they consume large amounts of energy because their propellers must constantly generate thrust. Airplanes, meanwhile, are extremely efficient because they use fixed wings to glide through the air, but they cannot stay suspended in one position like a bird watching its surroundings. Now, scientists have developed a new type of flying robot that combines the best features of both worlds. Researchers from the Max Planck Institute for Intelligent Systems and the University of Stuttgart have created a shape-changing robot called Floaty — a machine inspired by birds that can remain stable in the air while using very little energy. The research, published in npj Robotics , introduces a new approach to flight: instead of fighting against the air using power...

Human touch is one of the most powerful ways we understand the world around us. When we hold an object, our brain instantly recognizes its size, shape, softness, and hardness. Recreating this natural experience in robotic systems and wearable devices has been a major challenge for scientists and engineers. Now, researchers have developed a new technology called HapMorph , which brings us closer to realistic artificial touch by allowing devices to change both their size and stiffness at the same time. Haptic technology, which focuses on creating a sense of touch through mechanical feedback, plays an important role in the future of human-robot interaction, virtual reality, medical training, and wearable robotics. However, most existing haptic systems have a limitation: they can usually reproduce only one type of physical sensation. Some devices can change shape or size, while others can simulate hardness or softness. Combining both abilities in a small, wearable system has remained a dif...
