Uncover reality

Clean air is something most of us take for granted, yet it plays one of the biggest roles in protecting our health. Every day, air filters quietly work in the background to remove dust, pollen, smoke, bacteria and other harmful particles from the air we breathe. They are found in homes, hospitals, offices, factories, schools, vehicles and air purification systems around the world. Over the years, air filters have become better at trapping tiny particles. However, scientists have long faced one important problem that has been difficult to solve. Capturing harmful particles is only the first step. The bigger challenge is making sure those particles stay trapped instead of escaping back into the air. Now, researchers from the Republic of Korea have developed an innovative solution that could transform the future of air filtration. They created a unique self-renewing adhesive coating that allows filters to hold onto particles much more effectively while maintaining strong airflow. The tech...

Imagine launching a robot into space that starts as a flat structure but later unfolds, reshapes itself, and becomes a bridge, a tunnel, or even part of a future space habitat. It may sound like science fiction, but engineers have now taken a major step toward making this idea a reality. Researchers from North Carolina State University (NC State) have developed an innovative shape-shifting robot that can transform into more than 1,000 different configurations while using only three active motors . Inspired by the ancient art of origami , this remarkable robot could one day help astronauts build habitats on the Moon, Mars, or other space destinations without requiring heavy construction equipment. The research, published in the journal Nature Communications , demonstrates how a simple yet intelligent design can make future space missions more efficient, affordable, and flexible. A Robot That Changes Shape Unlike traditional robots that are built for a single task, this new robot is de...

A team of engineers and neuroscientists at the University of California San Diego (UC San Diego) has developed a groundbreaking wearable device that could make Parkinson's disease treatment safer and more personalized. The researchers have created a soft fingertip patch that continuously measures medication levels through a patient's sweat—without using a battery. The innovative device, described in the Proceedings of the National Academy of Sciences (PNAS) , provides real-time information about the amount of levodopa , the most widely used medicine for Parkinson's disease. The patch delivers results that closely match standard laboratory blood tests while offering continuous monitoring from the comfort of a patient's home. Experts believe this technology could help doctors prescribe the right dose at the right time, improving symptom control and reducing harmful side effects. A Major Challenge in Parkinson's Treatment Parkinson's disease is a progressive neuro...

Wearable health technology is becoming smarter and more powerful. Smartwatches, fitness bands and medical patches can already track important health signals such as heart rate, muscle activity and blood flow. However, there is still a major problem: different body signals usually require different sensors. This means that a device designed to monitor several health signals may need multiple sensors, separate electronic circuits and more space on the skin. The result can be a larger, less comfortable device that consumes more power. Researchers at the National University of Singapore (NUS) have developed a new technology that could change this approach. Led by Assistant Professor Liu Yuxin from the Department of Biomedical Engineering at the NUS College of Design and Engineering, the research team has created a cross-modal skin sensor called X-Sig . The device can combine electrical and mechanical signals from the body into a single signal, allowing different types of health informatio...

Wireless charging has already become part of everyday life. Smartphones, smartwatches, earbuds and other devices can now receive power without being physically connected to a cable. But researchers are taking the idea much further: wirelessly powering drones while they are still in the air. A research team has developed a lightweight device that can capture energy from a laser beam and convert it into electricity. The receiver is designed using ideas from solar-cell technology and can be mounted beneath a drone's wing. If the technology can eventually be made practical for real-world flight, drones could potentially remain airborne for much longer without landing to recharge or replace their batteries. The findings were published on July 29 in the journal Matter & Light . A New Way to Power Drones Drones are increasingly being used for forest inspections, disaster monitoring, surveillance, deliveries and other tasks that require them to stay in the air for long periods. However...

As technology continues to advance, the demand for efficient, compact, and sustainable energy solutions is increasing rapidly. From smart watches and fitness trackers to electric vehicles and wearable electronics, modern devices require reliable sources of power. However, current energy systems often depend on separate components for energy generation and storage, creating challenges in terms of size, weight, and flexibility. A new generation of energy technology is emerging with the development of energy harvesting and storing ribbons —innovative devices capable of collecting solar energy and storing it within the same structure. These flexible ribbons could transform the way we power portable electronics, wearable devices, vehicles, and even future smart textiles. The Challenge of Traditional Solar Energy Systems Today, most portable electronic devices rely on rechargeable batteries for energy storage, even when they are used in environments with abundant sunlight. In conventional so...

For decades, scientists searching for intelligent alien civilizations have focused on one big idea—the Dyson Sphere , a gigantic megastructure built around a star to capture its energy. If such structures existed, they would produce a huge amount of waste heat that telescopes could detect in infrared light. But despite years of searching, no confirmed Dyson Sphere has ever been found. Now, a fascinating new scientific proposal suggests that we may have been looking for the wrong kind of technology all along. Instead of capturing a star's light, an advanced civilization might be harvesting something far more subtle— the spin of the star itself . The idea comes from a new research paper written by Turkish high school student Sahin Torlakcik , who proposes an entirely new type of technosignature—evidence of alien technology—that could be much harder to detect than a Dyson Sphere. A Different Way to Power an Advanced Civilization Stars are not only giant balls of hot gas producing enor...
