Potential applications range from biomedical imaging to the conversion of light energy. University of Tokyo researchers Shinjiro Takano, Yuya Hamasaki, and Tatsuya Tsukuda have directly imaged how the geometric arrangement of atoms in gold nanoclusters develops at the very earliest stages of growth....
A research team has discovered how to finely control Dirac plasmon polaritons in topological insulator metamaterials, overcoming long-standing challenges in the terahertz range. In today’s world of advanced nanotechnology, the ability to control light at extremely small scales is essential for break...
Penn State scientists discovered seven new ceramics by simply removing oxygen—opening a path to materials once beyond reach. Sometimes, less truly is more. By removing oxygen during the synthesis process, a team of materials scientists at Penn State successfully created seven new high-entropy oxides...
Scientists have captured an unprecedented, real-time view of influenza viruses as they move across and slip inside human cells. The footage reveals that cells are far from passive targets and instead push and pull against the virus in a surprisingly active struggle. Viewing Influenza Infection With ...
A new ultra-sensitive imaging system can make cancer cells light up, paving the way for faster and earlier detection. Researchers have created a compact Raman imaging system that can reliably tell tumor tissue apart from normal tissue. The goal is to support earlier cancer detection and make molecul...
Scientists have shown that it may be possible to transform materials simply by triggering internal quantum ripples rather than blasting them with intense light. Imagine being able to change what a material is capable of simply by shining light on it. That idea may sound like something out of science...
A newly developed imaging method blends ultrasound and photoacoustics to capture both tissue structure and blood-vessel function in 3D. By blending two powerful imaging methods, researchers from Caltech and USC have developed a new way to see inside the human body with unprecedented speed and detail...
New research may help reduce reliance on rare earth elements used to power modern technology. Scientists at the University of New Hampshire are using artificial intelligence to dramatically speed up the search for new magnetic materials. Their approach has produced a searchable database containing 6...

A new manufacturing approach aims to reshape how one of industry’s hardest materials is made. Tungsten carbide-cobalt (WC–Co) sits behind many of the sharp, long-lasting tool edges that cut through metal, concrete, and rock. Its standout hardness is also its biggest manufacturing headache. Once this...
MXenes are an emerging class of two-dimensional materials whose properties depend sensitively on the atoms bound to their surfaces. A new synthesis approach now allows researchers to control these surface terminations with unprecedented precision. First identified in 2011, MXenes are a fast-expandin...
