Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, ...

Researchers used the Poisson spot effect to create stable optical skyrmions with a laser and disc, simplifying studies for ...

When viruses travel through the air in tiny droplets, they can quickly start to dry out. Yet many viruses remain infectious after rehydration—something that is still not fully understood. Now, an ...

A new nanopatterned structure based on sub-wavelength physics has proved its value in a real-world setting, and it could ...

Single atoms are probably not replacing smartphone cameras soon, but an atom can be used to measure light. One research group ...

An instrument on the Perseverance rover has identified large, complex carbon compounds alongside unusual patterns on the ...

Quantum dot (QD) lasers enable intrinsically feedback-tolerant, isolator-free silicon photonic integrated circuits (PICs), eliminating the bulky optical isolators traditionally required to suppress ...

The whole dome of night sky was awash with color: cascades of yellow-green and blushes of crimson fanning from a darker point high overhead. As they fell in broad rays, they shifted and changed in ...

Materials science is the domain of understanding materials at the microscopic, often atomic, level to improve them. The most common goal is to make a material stronger than in its classical form, be ...
