Uncover reality

In the universe, some of the most powerful objects are not stars or planets, but supermassive black holes . These black holes sit at the centers of galaxies and can contain millions to billions of times the mass of our Sun. Even though they are small compared to their host galaxies, they can strongly influence everything around them. One of the best places to study this effect is the Centaurus cluster , a huge collection of galaxies filled with hot gas. At its center is a galaxy called NGC 4696 , which hosts a supermassive black hole that is actively shaping its environment. Scientists are trying to understand how this black hole “talks” to its galaxy and controls how much gas turns into stars. This process is called AGN feedback , and it is one of the most important ideas in modern astronomy. A Galaxy Surrounded by Hot Gas NGC 4696 is not an isolated galaxy. It sits inside a giant cloud of extremely hot gas called the intracluster medium . This gas is so hot that it shines in X-rays a...

Neutron stars are some of the most fascinating objects in the universe. They are formed when massive stars run out of fuel and explode in giant supernova explosions. What remains is an incredibly dense object packed with matter. A neutron star can contain more mass than our Sun while being only about 20 kilometers wide. Because of their extreme conditions, neutron stars have been a mystery to scientists for decades. Now, a new study has revealed an unexpected behavior inside the crust of neutron stars that could help explain powerful cosmic events such as magnetar bursts, starquakes, and even some fast radio bursts. Using advanced computer simulations, researchers led by Caplan studied how neutron star crusts bend, crack, and respond to stress. What they found was something scientists had never clearly seen before—a hidden state of steady flow that appears after the crust breaks. The Strongest Material in the Universe Scientists believe that the crust of a neutron star is one of the st...

 For decades, astronomers believed that the region surrounding our Solar System was far too hostile for many complex molecules to survive. But a new discovery has challenged that assumption and revealed that space may be far more resilient than scientists once thought. Researchers have created the most detailed three-dimensional map yet of a giant cosmic structure known as the Local Bubble . Their findings show that mysterious interstellar molecules are somehow surviving inside this extreme environment, raising new questions about how matter behaves in space and how the galaxy evolves. What Is the Local Bubble? The Solar System does not travel through ordinary space. Instead, it sits inside a huge cavity called the Local Bubble. This bubble is a vast region of low-density gas that stretches hundreds of light-years across. Scientists believe it was created millions of years ago by multiple supernova explosions—powerful stellar explosions that blasted away much of the surrounding ma...

Wormholes are one of the most fascinating ideas in physics. They are often described as tunnels in space and time that could, in theory, connect distant parts of the universe. While no wormhole has ever been found in real space, scientists still study them using mathematics to understand what Einstein’s theory of gravity allows. A new theoretical work by Herr, Fournier & Hamilton explores a very unusual idea: a wormhole with three separate “necks” in a single, smooth spacetime structure . This is not an engineering discovery or an experimental result. It is a mathematical model based on Einstein’s equations of general relativity. Even so, it is important because it shows new possibilities for how spacetime can be shaped in theory. Where the Idea Comes From The concept of wormholes goes back to 1935, when Albert Einstein and Nathan Rosen studied solutions to Einstein’s equations. They proposed a structure now called the Einstein–Rosen bridge , which connects two regions of spacetime...

Self-driving cars are no longer a futuristic dream. They are already operating on roads in cities around the world, from London to San Francisco. These vehicles promise safer roads, fewer traffic jams, and greater convenience. However, one major challenge continues to hold back widespread public trust: when a driverless car crashes, it is often difficult to understand exactly why it happened. Now, researchers have developed a new way to answer that question. For the first time, scientists have created algorithms that can automatically explain why a self-driving car made a mistake and crashed. The breakthrough could help engineers improve autonomous vehicles and make them safer for everyone. The research was presented at the 2026 IEEE International Conference on Robotics and Automation by a team from King's College London. The Growing Presence of Self-Driving Cars Autonomous vehicles are becoming increasingly common across the globe. Technology companies and car manufacturers are i...

 For most people, chikungunya is a painful but temporary illness. After a mosquito bite, symptoms such as high fever, rash, fatigue, and severe joint pain usually disappear within a few weeks. However, for millions of people around the world, the story does not end there. Long after the fever is gone, intense joint pain and swelling can continue for months or even years, making everyday activities difficult and affecting quality of life. Now, scientists may have uncovered an important clue that explains why some chikungunya infections become chronic. A new study from researchers at the University of Colorado Anschutz Medical Campus suggests that the virus can hide inside specialized immune cells in joint tissues, allowing it to persist in the body and continue driving inflammation. The discovery could open the door to future treatments for a condition that currently has no specific cure. A Growing Global Health Concern Chikungunya virus is spread by infected Aedes mosquitoes, the ...

For years, creatine has been known as a popular supplement among athletes, bodybuilders, and fitness enthusiasts. It is widely used to improve strength, increase muscle performance, and support recovery after exercise. Now, a new scientific study suggests that creatine may have another remarkable ability—helping the immune system fight cancer. Researchers at the University of California, Los Angeles (UCLA) have discovered that creatine does more than support muscles. Their findings show that it can energize important immune cells that play a critical role in identifying and attacking cancer. The study, published in the journal iScience , reveals that creatine helps power dendritic cells, which are often described as the “teachers” of the immune system. This discovery builds on earlier research from the same team showing that creatine boosts the activity of killer T cells, the immune system’s main cancer-fighting soldiers. The new study shows that creatine supports not only the fighters...
