Uncover reality

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...

For decades, surgeons have successfully repaired congenital heart defects and saved countless lives. However, many patients who undergo heart surgery in childhood later develop problems such as abnormal heart rhythms and disturbances in the way their hearts beat. Now, a groundbreaking study has revealed a hidden part of the heart that may help explain why these complications occur. Researchers from University College London (UCL) and the European Synchrotron Radiation Facility (ESRF) have created the first-ever three-dimensional map of the heart’s electrical wiring in Tetralogy of Fallot, one of the most common congenital heart defects. Their findings provide an unprecedented view of the heart’s conduction system and could help surgeons perform safer operations while improving long-term outcomes for patients. The study is part of the international Human Organ Atlas project and was published in JTCVS Structural and Endovascular. Understanding Tetralogy of Fallot Congenital heart disease...

Why do we walk toward some people and ignore others? What makes one individual more social, while another prefers to stay quiet or distant? For a long time, these questions were thought to depend on personality or environment alone. But new research shows something even more surprising: the brain may be “deciding” to be social several seconds before we even move. A recent study published in Nature Communications reveals that social behavior is not a sudden action. Instead, it is prepared in advance through coordinated activity across the brain. The research was led by Dr. Lilah Avitan at the Hebrew University of Jerusalem and carried out at the Edmond and Lily Safra Center for Brain Sciences (ELSC). It offers a new way to understand how the brain generates social behavior—and why individuals differ in their social drive. 🐟 Why scientists studied zebrafish To understand how social decisions form in the brain, researchers used a small but powerful model organism: the zebrafish. Zebrafi...

Stroke recovery is often a long and difficult journey. After leaving the hospital, many patients struggle to continue regular rehabilitation because therapy can be expensive, time-consuming, and hard to access. Now, a new technology developed by engineers at the University of Houston could change that experience completely. They have created ultra-thin, paper-like sensors that stick to the skin like a bandage and help patients recover movement—by turning rehabilitation into a simple video game. This innovation is not just about medical improvement. It is also about making recovery easier, more engaging, and something patients can do at home without constant supervision. A Small Patch With Big Power The new device is a piezoelectric patch sensor. Piezoelectric materials have a special property: they generate tiny electrical signals when they are bent, stretched, or pressed. In this system, those signals are used to detect muscle movement in real time. Each sensor is extremely small—onl...
