Uncover reality

3D printing has become one of the most exciting technologies in the world. Today, it is used to make toys, tools, machine parts, medical implants, and even houses. The technology works by building an object layer by layer using melted plastic or other materials. Now, scientists have made an unexpected discovery. They found that the process of 3D printing naturally creates electric charges on the printed object. This hidden effect was not fully understood before, but it could help create smarter electronic devices, better sensors, and new materials in the future. The research, led by Lorenzett and his team , is the first detailed study to explore how electrical charges are created during 3D printing. Their findings could improve both 3D printing technology and our understanding of electricity. A Hidden Effect Inside Every 3D Print Most people think a 3D printer simply melts plastic and places it layer by layer to create an object. But the process is much more complex. Inside the printe...

How did our universe begin? This is one of the biggest questions in science. We know that the universe started with the Big Bang about 13.8 billion years ago . Soon after, it went through a period of incredibly fast expansion called cosmic inflation . But scientists still don't know what caused the universe to come into existence in the first place. A new study by physicists Janna Lavrelashvili and Jean-Luc Lehners offers an exciting idea. Their research suggests that our universe may have been born through a special type of wormhole . If this idea is correct, tiny clues from that event could still be visible today in the oldest light in the universe. What Is a Wormhole? Many people know wormholes from science fiction movies, where they are shown as shortcuts through space. However, the wormholes in this study are very different. These are theoretical structures predicted by the laws of physics. Instead of connecting two distant places in space, they may connect an old universe...

Imagine a glue that is so strong it can hold together slippery, nonstick Teflon surfaces and even lift an 8-kilogram weight , yet disappears completely with just a splash of alcohol. It may sound like science fiction, but researchers at the University of Tokyo have turned this idea into reality. This revolutionary adhesive could change the future of manufacturing, electronics, automobiles, and recycling by solving one of the biggest problems in material science: creating a glue that is both incredibly strong and easy to remove. The researchers have published their findings in the Journal of the American Chemical Society , where they describe a new adhesive that combines exceptional strength, flexibility, and complete removability. Why Traditional Glues Have a Major Problem For decades, scientists have struggled with a difficult challenge. Strong adhesives usually create permanent bonds, making them almost impossible to remove without damaging the surface or leaving behind sticky resi...

Imagine a tiny rescue worker that can crawl through collapsed buildings, squeeze into spaces too small for humans, and help rescuers locate trapped survivors. It may sound like science fiction, but researchers are turning this idea into reality with cyborg insects . A team led by Marc Marques has developed a 3D-printed artificial wing-like limb that dramatically improves the mobility of cyborg cockroaches. Inspired by the way ladybirds (ladybugs) flip themselves back onto their feet, this innovation could make insect-based rescue missions far more reliable during earthquakes, building collapses, and other disasters. What Are Cyborg Insects? Cyborg insects are real insects equipped with tiny electronic devices that allow scientists to monitor, communicate with, and even guide their movements. Unlike traditional robots, insects already have millions of years of evolution behind them. They can crawl over rough terrain, climb obstacles, and fit through narrow gaps that even the smallest...

Imagine an astronaut getting injured millions of kilometers away from Earth. Until now, doctors in space had only one reliable way to look inside the human body—ultrasound. But that has finally changed. In a groundbreaking achievement, scientists have successfully captured the first diagnostic X-rays in space , marking a major milestone in space medicine. The historic experiment was carried out during the Fram2 commercial space mission , and the results have now been published in the medical journal Radiology . This breakthrough could transform healthcare for astronauts on future missions to the Moon, Mars, and beyond. A Medical Milestone in Orbit For more than 40 years, astronauts have relied almost entirely on ultrasound scans to diagnose injuries and illnesses during space missions. While ultrasound is useful, it has important limitations. It requires trained operators, depends on special gel to transmit sound waves, and cannot provide the same level of detail as X-rays for many med...

Parkinson's disease affects millions of people worldwide, making everyday activities such as walking, writing, or even holding a cup of tea extremely difficult. For years, one of the most effective treatments for severe Parkinson's symptoms has been deep brain stimulation, a procedure that requires surgeons to implant electrodes deep inside the brain. While this treatment has helped many patients, it is expensive, invasive, and not suitable for everyone. Now, scientists have developed an exciting new approach that could one day replace traditional brain implants. Instead of using implanted electrodes, researchers have successfully used tiny magnetic particles and external magnetic fields to stimulate deep regions of the brain. In animal studies, this innovative technique significantly improved movement problems in mice with Parkinson's-like symptoms. The groundbreaking research was carried out by an international team of scientists from Friedrich-Alexander-Universität Erlan...

For nearly 200 years, Body Mass Index (BMI) has been one of the most widely used tools to determine whether a person is underweight, healthy, overweight, or obese. Doctors, hospitals, fitness experts, and health organizations around the world have relied on this simple calculation based on height and weight. However, many scientists have long argued that BMI is far from perfect. It often fails to reflect a person's true body composition, muscle mass, age, or fat distribution. Now, researchers believe they may have developed a more accurate alternative called the Consistent Body Mass Index (CBMI) . Published in the journal Scientific Reports , the new study suggests that CBMI could provide a better understanding of a person's physical health by using mathematics, geometry, and real-world body measurements. Why BMI Has Been Questioned for Years The Body Mass Index was created in the 1830s by Belgian mathematician Adolphe Quetelet . Interestingly, BMI was never designed to evalu...
