When waves meet a gap or an edge in a barrier, they continue through the gap or past the edge of the barrier. This may seem obvious but what happens on the far side of the gap or barrier is not so ...

Imaging-based single-cell physiological profiling holds great potential for uncovering fundamental bacterial cold shock response (CSR) mechanisms, but its application is impeded by severe focus drift ...

Engineers at the University of Florida have built a photonic chip that performs convolutions, the most compute-heavy operation in modern AI, using light instead of electricity and delivering roughly ...

Astronomers are now creating 'artificial stars' using powerful lasers to overcome Earth's atmospheric distortions that blur ...

Microresonators are micrometre-scale structures for confining light. Light is reflected internally at the edges of the resonator. This creates a series of standing-wave optical modes, or resonances, ...
