Uncover reality

3D printing once belonged almost entirely to the world of science fiction. Stories imagined futuristic machines capable of creating tools, objects, and even entire structures with the push of a button. Today, that idea has become part of everyday life. Affordable 3D printers now sit in homes, schools, workshops, and offices around the world, allowing people to create everything from decorative objects and board game pieces to replacement parts for broken appliances. One of the biggest reasons for the popularity of 3D printing is freedom. Instead of buying products, people can design and manufacture them themselves. However, while the technology has grown rapidly, one important problem has remained unresolved: waste. Researchers at Yokohama National University may now have found an answer. They developed a new kind of recyclable resin for high-precision 3D printing that can be reused multiple times without significantly losing performance. Their work, published in ACS Omega , could help...

Imagine driving through a busy city street during rush hour. Cars move quickly from every direction, bicycles weave between lanes, and people cross the road in unpredictable patterns. At the same time, sunlight reflects off glass buildings, shop windows glare brightly, and shadows shift as you move forward. Yet, your brain handles all of this effortlessly. Without conscious effort, it builds a stable 3D understanding of the world—estimating distances, recognizing objects, and tracking movement in real time. This ability feels simple to us, but for machines, it is one of the hardest problems in science and engineering. Now, researchers are working to change that. A team from the Computational 3D Imaging and Measurement Lab at the University of Arizona, led by Florian Willomitzer, is developing a new generation of 3D vision systems that may eventually outperform human sight in certain conditions. Their work, published in Nature Communications, takes a major step toward what they call “su...

Dark matter is one of the biggest mysteries in modern science. We know it exists because of its gravity, but we cannot see it, touch it, or directly detect it. It does not emit light, so it is completely invisible. Yet, it plays a very important role in the Universe. Scientists estimate that about 27% of the Universe is made of dark matter. It helps galaxies stay together, affects how stars move, and shapes the large structures of the Universe. But despite decades of research, we still do not know what it is made of. For a long time, scientists believed dark matter might be made of new types of particles. However, many experiments have tried and failed to find them. Because of this, researchers are now exploring other possibilities. One of the most interesting ideas is that dark matter might be made of tiny black holes. What Are These Tiny Black Holes? Black holes are usually formed when large stars die and collapse under their own gravity. But there is another type of black hole that...

For many years, scientists have studied how galaxies and other giant structures move through space. They have learned a lot about the Universe by observing objects moving toward Earth or away from it. But one important type of motion remained mostly hidden: movement across the sky, also called sideways or transverse motion. Now, a team of researchers led by Hotinli has made an important discovery. For the first time, they have detected something called the moving lens effect , a tiny signal hidden inside the oldest light in the Universe. This discovery gives scientists a completely new way to study how large objects move through space and may help create a three-dimensional map of motion across the Universe. This achievement opens a new chapter in understanding gravity, cosmic structure formation, and the history of the Universe. The Universe Is Always Moving The Universe is not standing still. Galaxies, galaxy clusters, and huge regions filled with matter are constantly moving because...

Modern electronic devices have become smarter, smaller, and more powerful than ever before. From wearable health trackers and smart displays to remote sensors and implantable medical devices, technology is now deeply integrated into everyday life. However, despite all these advances, almost every device still depends on one essential requirement: a power source. Traditional power systems create several challenges. Batteries eventually run out and need replacement or recharging. In many situations, such as remote locations, wearable systems, or large-scale sensor networks, replacing batteries repeatedly is inconvenient and costly. This is why scientists are increasingly interested in self-powered technologies that can harvest energy directly from the surrounding environment. A research team led by Wei has introduced an exciting innovation in this field: a self-powered electroluminescent system that operates without an electrical interface and can be expanded to larger areas. The system ...

In a surprising breakthrough that reshapes how scientists understand space weather, researchers have discovered a rare physical phenomenon—known as the Zwan–Wolf effect —inside the atmosphere of Mars. Until now, this effect had only ever been observed in Earth’s magnetic environment. Its appearance on Mars suggests that even planets without a global magnetic field can experience complex, magnet-like behavior deep within their atmospheres. The discovery came from data collected by NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft during a powerful solar storm in December 2023. What initially looked like strange “wiggles” in the data turned out to be something far more significant: charged particles in Mars’ ionosphere being squeezed and structured in a way never seen before on another planet. A Hidden Pattern Discovered in Mars Data The finding was not planned. Scientists were reviewing MAVEN’s atmospheric measurements when they noticed unusual fluctuations in the magnet...

The total solar eclipse on 21 August 2017 was much more than a beautiful event that attracted millions of skywatchers across the United States. For scientists, it became a rare natural experiment — a chance to test whether computers could accurately predict what the Sun’s mysterious outer atmosphere, called the corona, would look like before anyone actually saw it. A team led by researcher Mikic developed a new and improved model of the Sun's corona and made a bold prediction one week before the eclipse happened. After the eclipse occurred, they compared their predictions with real observations. The results showed that the model performed remarkably well and also revealed areas where our understanding of the Sun still needs improvement. This work could help scientists make better space weather forecasts in the future, protecting satellites, communication systems, and power grids on Earth.   Why Solar Eclipses Matter to Scientists Normally, the Sun's bright surface is so intense...
