Why some rotating machines waste the most energy at a specific speed
Many machines we rely on every day—from industrial mixers and cooling systems to power transmission devices—use rotating parts to move liquids.
In many real-world systems,...
We think of mushrooms as food. But mycelium-based blocks could be the future of...
When mushrooms make the news, it's often for grim reasons—a mysterious poisoning, toxic species in the bush, or high-profile court cases.
But the mushroom itself...
Scientists create smart fabrics that defy physics and absorb impact
Most of us expect materials to behave in a familiar way. When you pull on fabric, it stretches longer and becomes thinner.
This is true...
Why the next generation of robots will have tendons instead of motors
At the Soft Robotics Lab at ETH Zurich, the scene looks less like a traditional engineering workshop and more like a child’s playroom mixed...
A simple non-stick trick could make green hydrogen much cheaper
A material best known for keeping eggs from sticking to frying pans may help solve one of clean energy’s biggest challenges.
Researchers have discovered...
This robotic dog can remember every step—and it could save lives
Imagine a robotic dog that can see its surroundings, remember where it has been, understand spoken instructions, and make smart decisions in real time.
That...
This new chip uses sound waves to grab and move tiny objects
Sound is usually something we hear, not something we touch.
But researchers at Virginia Tech have found a way to turn acoustic waves into invisible...
Scientists create powerful new tool to explore the microbial universe
Microbes are everywhere. They live in our bodies, in soil, in the oceans, and even in the air we breathe.
These microscopic organisms play a...
Smart AI headphones could learn who you’re talking to—and make their voices clearer
Having a conversation in a busy café or crowded room can be exhausting. Many people struggle to focus on the person they’re speaking with...
Scientists create nearly invisible window insulation that blocks heat
Physicists at the University of Colorado Boulder have developed a new window insulation material that could dramatically cut energy loss from buildings without blocking...
AI can spot missed Alzheimer’s diagnoses in medical records
Researchers at UCLA have created a new artificial intelligence (AI) tool that may help find people with undiagnosed Alzheimer’s disease by looking at their...
Smart bandage uses AI to speed up wound healing
Engineers at the University of California, Santa Cruz have developed a new smart bandage called “a-Heal” that may change how we treat wounds.
This wireless...

Scientists develop micro power prototype to boost energy efficiency
A micro-combined heat and power (mCHP) prototype that utilizes a piston engine, achieving an impressive energy efficiency of over 93%.
Ultrasound can make stronger 3D-printed alloys
Researchers have used sound vibrations to shake metal alloy grains into tighter formation during 3D printing.
A study just published in Nature Communications shows high...
Ocean cables: The new watchdogs against tsunamis
Imagine a world where we can detect tsunamis, those giant waves caused by underwater earthquakes, way before they reach our shores, giving us time...
