Pocket-sized printer can make origami sensors anywhere

Imagine being able to print a medical sensor or an agricultural device right where you need it—whether in a hospital, a farm, a disaster...

Engineers turn cardboard and soil into concrete alternative

Australian engineers have created a surprising new building material that could dramatically cut the environmental cost of construction. By combining cardboard, soil, and water, they...

Scientists use diamonds to unlock next-generation quantum devices

Diamonds may be best known for their sparkle, but scientists are now showing that these gems could be just as valuable for powering the...

Researchers build world’s smallest light-powered gears on a chip

Gears are a familiar part of our daily lives, helping machines of every size run smoothly—from cars and clocks to wind turbines and robots. But...

Flawed but better: How defects are making graphene more powerful

Graphene has long been called a “wonder material.” Just one atom thick, it is incredibly strong, light, and an excellent conductor of electricity. But surprisingly,...

This clever 3D-printed device could stop dangerous vibrations in rotating machines

Rotating parts like boat propellers, turbines, and hydraulic pumps often face a serious problem: vibration caused by swirling currents of air or water. These vibrations...

Scientists unlock leak-tight ceramic 3D printing for next-gen chemical reactors

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) have developed a new way to 3D print ceramics that could transform...

Golden conductive plastic could put the human body online, shows study

It looks like gold, bends like plastic, and can carry electricity. A new recipe for making electrically conductive plastic could open the door to a...

Scientists create adaptive cooling clothes that react to body heat and sweat

As global temperatures rise, extreme heat is becoming one of the biggest threats to health and daily life. Around 3.6 billion people already live in...

Scientists create ultra-thin optical sensor that feels like human skin

Imagine a touch sensor so thin and flexible it can feel not only where you press but also how hard. Scientists in Japan have just...
