Uncover reality

New research reveals that the mysterious masses of particles inside neutron stars could play a major role in determining how quickly these extreme cosmic objects lose their heat. Neutron stars are among the strangest and most extreme objects in the universe. Formed when massive stars collapse at the end of their lives, these incredibly dense objects pack more mass than the Sun into a sphere roughly the size of a city. Their interiors contain matter under extraordinary pressure and density, creating physical conditions that cannot be easily reproduced in laboratories on Earth. Although neutron stars are born extremely hot, they gradually lose their heat over time. Surprisingly, some neutron stars cool much faster than others. Scientists have been studying this difference for years, and new research suggests that the answer may lie in the unusual properties of particles inside these stellar objects. A study by researchers Sugiyama and Dohi has investigated how the effective masses of par...

Imagine billions of people breathing in and out every day. Every time we exhale, our bodies release carbon dioxide (CO₂) into the atmosphere. Now, scientists have discovered that the total amount of carbon dioxide produced by human bodies worldwide is surprisingly enormous: more than 2 billion metric tonnes every year. A new study has revealed that human metabolism produces around 2.05 billion metric tonnes of CO₂ annually. Even more surprising, this amount has increased by 74% over the past three decades, mainly because the world's population has grown. However, before worrying about the carbon dioxide released every time you breathe, there is an important distinction to understand. Unlike the emissions produced by cars, factories, and power plants, the CO₂ released by our bodies does not directly add new carbon to the atmosphere. Instead, it is part of the Earth's natural carbon cycle. The discovery could nevertheless help scientists understand how carbon moves around the pla...

The young Earth once spun so rapidly that a day lasted just two to five hours. Scientists now believe that as our planet gradually slowed down and changed shape, it may have triggered powerful geological movements that helped shape Earth's earliest crust and lay the foundations for the continents we know today. Around 4.5 billion years ago, Earth was a very different world. It was still young, extremely hot and spinning much faster than it does today. During this early period, a Mars-sized object collided with the newly formed planet. The enormous impact sent massive amounts of material into space, eventually creating the Moon. However, this collision did more than create Earth's natural satellite. It also left our planet rotating at an extraordinary speed. Scientists estimate that a day on early Earth may have lasted only two to five hours. Now, new research suggests that Earth's gradual slowdown may have played a much bigger role in shaping the planet than previously unde...

Imagine falling into the ocean during an emergency, far away from the shore, with no way to call for help. Your life jacket could become your most important source of rescue—not just by keeping you afloat, but also by generating its own electricity to send a distress signal. Scientists have developed an innovative technology that could make this possible. Researchers from the University of Wollongong (UOW), Australia, and their international collaborators have created a soft, flexible device that generates electricity from everyday movements. It can use the movement of ocean waves, body movements, or even a small flick of the wrist to produce electrical energy. The technology could lead to a new generation of battery-free wearable devices, including smarter life jackets, health-monitoring sensors, and soft robots. The research was published in the scientific journal Science Advances in 2026. A Life Jacket That Produces Its Own Electricity Traditional electronic life jackets often depe...

For decades, 3D printing technology has faced a major challenge: achieving high speed, fine details and strong material performance at the same time. Existing printing methods can deliver some of these advantages, but combining all of them into a single process has remained difficult. Now, engineers at Northwestern University have developed a groundbreaking 3D printing technique that could overcome these limitations and open new possibilities in manufacturing, robotics, energy storage and medicine. The new technology, called Direct Ink Additive Lithography (DIAL) , combines the speed and precision of light-based 3D printing with the ability of extrusion-based printing to work with thick, functional materials. Instead of building objects by slowly depositing material one line at a time, DIAL spreads thick, paste-like inks into extremely thin layers and uses patterned light to harden selected areas into precise shapes. The researchers published their findings in the journal Science Advan...

Imagine a tiny liquid droplet that can rise and sink repeatedly inside a liquid without being pushed by an external force. Even more surprisingly, it can move at speeds of up to 25 millimetres per second and continue this unusual motion for as long as 25 minutes. This may sound like something from science fiction, but scientists have demonstrated exactly this behaviour using a hydrogen-powered mechanism called the hydrogen microbubble elevator . In a fascinating development, researchers led by Fattahi Kobra have discovered a new way to make liquid droplets move autonomously. Their approach uses chemical reactions occurring inside specially designed droplets to generate tiny hydrogen bubbles. These bubbles continuously change the droplet's density, allowing it to rise and sink like a miniature elevator. The discovery could open new possibilities in active soft matter, microscopic transport systems and chemical-powered machines. What Is Active Soft Matter? Active soft matter refers t...

Imagine a tiny insect shooting a drop of waste away from its body like a miniature water-powered rocket. It may sound unusual, but scientists have discovered that sharpshooter insects use a remarkable physical mechanism to launch their waste droplets farther and faster while consuming very little energy. This discovery reveals an extraordinary example of how nature uses physics to solve everyday survival challenges. Researchers have found that these insects take advantage of a phenomenon called droplet superpropulsion , which allows a tiny liquid droplet to move faster than the structure responsible for launching it. The findings could also inspire new technologies, including energy-efficient robots, self-cleaning surfaces, and microscopic machines. The Unusual Feeding Habits of Sharpshooter Insects Sharpshooters are tiny insects belonging to the Cicadellidae family. Despite their small size, they have a very unusual diet. Unlike many insects that consume nutrient-rich plant materials,...
