By using a laser to generate ultrasound waves that reveal structural changes, photoacoustic tomography (PAT) has shown its value in identifying disease conditions in the microvasculature, the tiny vessels that extend from major veins and arteries. To this point, however, the process has been too slow to capture this information in real time, limiting its value in clinical settings.

PASADENA, Calif., Oct. 8, 2024 — Despite the danger stroke presents to large segments of the population, clinicians have historically been at a disadvantage in successfully identifying those at grave risk of having a stroke ahead of time. But a team at the California Institute of Technology and other institutions have created a headset, based on relatively basic laser and detector technology, which could be fitted on patients and dramatically change the health trajectory of those at risk.

Research in optics and photonics as well as advancements in the design of versatile bedside systems have achieved breakthroughs in everything from our understanding of cellular metabolism to the ablation of scar tissue after an injury. But this research has too often been focused on concentrated groups of potential patients, geographically and demographically, which causes significant portions of the population that could be served by these breakthroughs to be underrepresented.

Miniaturized devices built around various fiber configurations are inserted into the tight, winding systems within the body to guide surgeons at the nanometer level. The growing incidence of chronic diseases around the world has driven the expansion of techniques to provide diagnosis at the source, which would ideally involve a minimally invasive — but detail-rich — application of technology.

When ancestors of modern endoscopy first peered into cavities of the human body, they used candlelight or burned a mixture of alcohol and turpentine, which illuminated a thin tube equipped with a lens. In the 19th century, the French inventor Antonin Jean Desormeaux, who is regarded as the father of endoscopy, used such a device to guide chemical cauterization, a simple and painful procedure in which a chemical agent is applied to infected tissue.

Scientists have long believed that when cuttlefish camouflage in response to danger, they physiologically choose a color pattern from a limited number of pigmentation schemes to best match their surroundings. But a team of researchers from Asia and Europe has determined it to be a far more complicated process than that. Rather than selecting colors from a limited number of patterns, the common European cuttlefish, Sepia officinalis, mixes and matches colors until it finds the best style.

For biomedical researchers working with cell culture, an accurate, real-time reading of progression and confluency (density) in cell populations is their ultimate objective. The information gleaned from imaging these samples is valuable in understanding cell proliferation and functionality at its most fundamental stages as well as tracking specific therapeutics in the tissue of patients.
