Uncover reality

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...

Imagine holding a hot cup of tea on a winter morning or walking barefoot on a cool marble floor. Within a fraction of a second, your brain knows exactly whether something feels warm or cool. But have you ever wondered how your skin sends this information? For decades, scientists believed that our skin used two separate groups of nerve cells—one to detect warmth and another to detect cool temperatures. However, a groundbreaking new study has challenged this long-held belief. Researchers have discovered that the human body uses a much smarter and simpler system than previously imagined. The findings not only change our understanding of how we experience temperature but could also help scientists develop better treatments for nerve disorders, chronic pain, and diseases that affect temperature sensation. A Long-Standing Scientific Belief Gets Challenged For many years, biology textbooks explained that different nerve cells were responsible for detecting warm and cool temperatures. Accordin...

Imagine wearing a health sensor on your face that no one can see—not even people standing right next to you. It doesn't feel uncomfortable, doesn't change the way you look, and still tracks important health signals with impressive accuracy. This futuristic technology may soon become a reality thanks to a breakthrough by researchers from the Institute of Industrial Science at The University of Tokyo and their collaborators. The research, published in Science Advances , introduces a new generation of ultrathin, stretchable skin sensors that are almost completely invisible when placed on the face. These sensors can monitor important biological signals while blending naturally with the skin, making them far more comfortable and practical than today's wearable health devices. Why Current Wearable Sensors Have a Problem Wearable health technology has become increasingly popular over the past few years. Smartwatches, fitness bands, and medical patches are now commonly used to mon...

Every day, thousands of people around the world wait for the phone call that could save their lives—a call telling them that a donor organ has become available. In the United States alone, more than 100,000 people are waiting for a life-saving organ transplant , and many of them need a healthy liver. Unfortunately, not every donated liver is suitable for transplantation, and doctors often have only limited information to determine whether an organ is healthy enough to use. Now, scientists have developed an innovative technology that could dramatically improve how donor livers are evaluated before transplantation. The new system continuously monitors the health of a liver in real time, giving doctors a much clearer picture of how well the organ is functioning. This breakthrough could help save more donor organs, reduce transplant failures, and ultimately save countless lives. A New Way to Evaluate Donor Livers The research was led by Dr. Yangzhi Zhu , Assistant Professor and Principal ...
