Oxford Engineers Develop Ultra-Low-Cost Method to Build Soft Robots in Minutes

Imagine creating a robot that can bend, grip, crawl, or even swim—all in under 10 minutes and for less than ten cents. That’s exactly what a team of engineers at the University of Oxford has achieved, opening the door for rapid, affordable, and creative experimentation in the world of soft robotics. Their groundbreaking work, published in Advanced Science , could transform how researchers, start-ups, and even students approach the design and construction of flexible robots. Breaking Barriers in Soft Robotics Soft robots are made from compliant, bendable materials that mimic the flexibility of living organisms. Unlike traditional rigid robots, soft robots can delicately handle fragile objects, squeeze through tight spaces, or adapt to unpredictable environments. These abilities make them ideal for applications such as search-and-rescue operations, minimally invasive surgery, wearable devices, and adaptive manufacturing. However, despite their promise, soft robots have been challenging t...

Scientists Revealed Brine Shrimp’s Swimming Secrets Could Help Tiny Robots Deliver Drugs to Tumors

Imagine tiny swimmers, smaller than the width of a human hair, gracefully moving through water in ways that defy our everyday understanding of physics. These aren’t just microscopic organisms or particles—they belong to a special realm called the mesoscale , bridging the gap between the microscopic and macroscopic worlds. Now, physicists at Aalto University are uncovering how these small creatures swim so efficiently, paving the way for microscopic robots capable of delivering drugs directly inside the human body. What is the Mesoscale? Physics is often divided into different scales. In the macroscopic world —the world of humans, cars, and planets—motion is dominated by inertia , the tendency of objects to keep moving unless acted on by a force. In the microscopic world —think bacteria and molecules— viscosity dominates, meaning that water feels almost like honey and tiny organisms must work hard to move. The mesoscale sits in between these two extremes. Here, neither inertia nor v...

The Coldest “Stars” in the Galaxy Might Actually Be Alien Megastructures

For decades, scientists have wondered whether advanced alien civilizations might build enormous structures around their stars to capture energy. These hypothetical constructions are called Dyson Spheres , and they remain one of the most fascinating ideas in the search for extraterrestrial intelligence. Recently, a new study by Amirnezam Amiri explored an intriguing question: If a Dyson sphere really existed, what would it look like to astronomers observing the sky? The answer may be surprising. According to the research, the coldest “stars” in our galaxy might not be stars at all. Instead, they could be enormous alien-built structures hiding the light of their host stars. This idea opens a new pathway for scientists searching for technological civilizations somewhere in the Milky Way. The Idea Behind Dyson Spheres The concept of a Dyson sphere was first proposed in 1960 by Freeman Dyson . Dyson suggested that an extremely advanced civilization might need vast amounts of energy to pow...

This “Super Foam” Absorbs 10× More Impact Than Normal Padding Could Make Helmets, Cars & Aircraft Much Safer

Scientists from Texas A&M University and the DEVCOM Army Research Laboratory (ARL) have developed a revolutionary material known as “super foam,” capable of absorbing up to ten times more energy than conventional padding materials. This innovation could transform industries ranging from military defense and aerospace to automotive safety and consumer products . The research, published in the journal Composite Structures , introduces a hybrid material created by combining traditional foam with 3D-printed elastic plastic structures . The result is a lightweight, affordable, and extremely durable composite that significantly improves energy absorption during impacts. Leading the project is Dr. Mohammad Naraghi , director of the Nanostructured Materials Lab at the Texas A&M College of Engineering, working alongside Dr. Eric Wetzel , team leader for Strategic Polymers Additive Manufacturing at ARL. Their work demonstrates how combining two simple materials can create a powerful ...

Scientists Create AI-Evolved Robots That Can Survive Being Cut in Half

Engineers at Northwestern University have developed a groundbreaking new type of robot that can adapt, survive damage and keep moving even in harsh outdoor environments. These robots, called “legged metamachines,” represent a major step forward in robotics because they are not fixed machines with rigid bodies. Instead, they are made from small robotic modules that can connect, disconnect and reorganize themselves to perform different tasks. The research describing these innovative robots was published in the prestigious journal Proceedings of the National Academy of Sciences , highlighting their scientific importance. Unlike traditional robots that stop working when a single part fails, metamachines can survive serious damage. If a piece breaks off, the remaining parts keep moving, while the broken module can still function independently and even rejoin the group later. This remarkable resilience makes these robots more similar to living organisms than machines. A Robot Built From Ma...

What’s Inside a Neutron Star? Gravitational Waves May Reveal the Answer

Neutron stars are among the most mysterious and extreme objects in the universe. These compact cosmic bodies pack more mass than our Sun into a sphere only about 20 kilometers wide. Their densities are so enormous that a single teaspoon of neutron-star material would weigh billions of tons on Earth. Despite being discovered more than 50 years ago, scientists still do not fully understand what lies inside neutron stars. The extreme conditions inside them cannot be recreated in laboratories on Earth. However, a new theoretical breakthrough may finally help scientists unlock their secrets. Researchers from the University of Illinois Urbana-Champaign, together with scientists from the University of California Santa Barbara, Montana State University, and the Tata Institute of Fundamental Research in India, have developed a new method to study the internal structure of neutron stars using gravitational waves. Their research, published in Physical Review Letters on February 18, 2026, provide...

Scientists May Have Found the Earliest Human Ancestor Ever Suggesting Humans Didn’t First Evolve in Africa

Walking on two legs is one of the most defining features of humans. This ability, known as bipedalism , separates humans from most other animals, especially our closest relatives like chimpanzees and gorillas. For many years, scientists believed that early humans first evolved in Africa and began walking upright around 6 million years ago . However, a remarkable fossil discovery in Europe is now challenging that long-held idea. A newly discovered 7.2-million-year-old thighbone in Bulgaria suggests that early human ancestors may have started walking on two legs much earlier—and possibly outside Africa . This discovery could reshape our understanding of how and where humans first evolved. A Fossil Discovery That Could Change History The fossil was discovered at the Azmaka excavation site near the town of Chirpan in Bulgaria , located in the Upper Thracian Plain. Researchers from several international institutions studied the fossil and published their findings in the scientific journal ...
