Although medical imaging technology has allowed scientists to image the brain on a macroscopic level, there is still much to be learned at a finer resolution. Optical microscopy can provide this resolution, and fluorescence-based optical imaging even enables researchers to visualize functional dynamics.
But despite this increased resolution, traditional one-photon microscopy can only image up to a certain depth. A feature article in the April issue of Optica’s magazine Optics & Photonics News (OPN) explores how multiphoton microscopy, in which excitation of fluorophores is performed using more than one photon, could revolutionize our ability to see deeper into biological tissues. |

Laboratories that operate autonomously using AI and robotics—so-called self-driving labs—are increasingly being explored as a transformative approach to accelerate scientific discovery. These platforms can formulate hypotheses, run experiments, analyze data, and adjust parameters on the fly, without the need for constant human intervention.
A feature article in the April issue of Optica’s magazine Optics & Photonics News (OPN) highlights how technological advancements in computing and instrumentation have vastly expanded our capabilities, and experiments now regularly leverage automation, simulations and big data to accelerate the pace of scientific discovery. The article examines how self-driving labs are used in fields ranging from materials science to drug discovery, and what their rise could mean for the future of research workflows. |

| Angela Dudley advises young scientists to find an enthusiastic mentor who can challenge and teach them about all aspects of science, from solid research skills to writing grant proposals. She was fortunate to have a few mentors throughout her career whose open-door policies helped her make connections. Actively participating in academic societies as a student is a great way to connect with potential mentors, as is taking the initiative and contacting researchers whose work you admire. |
