As we breathe, the volume of gases in the lungs is continually changing with varying degrees of inhalation and exhalation. These volumes are medically important for clinical assessment and diagnosis of respiratory pathologies. A light-based technology known as gas-in-scattering-media absorption spectroscopy (GASMAS) may allow noninvasive optical sensing of respiratory volumes.

Scientists have discovered a new type of nerve cell in the retina. The discovery marks a notable development for the field as scientists work toward a better understanding of the central nervous system by identifying all classes of neurons and their connections.

Researchers have developed a new test to more easily diagnose medulloblastoma, the most common malignant childhood brain tumor.

Researchers have been exploring the role of symbiotic skin bacteria in wound healing for different fish species. They also demonstrated that fish can be an excellent model for exploring the mechanisms of wound healing.

A new study published in Gastroenterology demonstrates that acinar cells within the pancreas can form new cell types to mitigate injury, however, this transition makes them susceptible to cancer-causing mutations.

Proteins bind to one another through a complex mix of chemical interactions. What if some proteins bind due to their shapes, a much simpler process?

Thermoelectrochemical cells show promise in utilizing waste heat to generate electrical energy. However, a low conversion efficiency has limited their application. Now, scientists have designed a novel hybrid thermoelectrochemical-concentration cell that outperforms similar state-of-the-art devices, opening doors to commercially feasible energy harvesting systems.

Two distinct ways have bee identified that people with HIV can control the virus for an extended period after stopping antiretroviral therapy under medical supervision. This could inform efforts to develop new tools to help people with HIV put the virus into remission without taking lifelong medication, which can have long-term side-effects.

Scientists have taken a closer look at how mitochondria are maintained in nondividing cells, such as neurons, with the ultimate goal of developing a better understanding of how to prevent or treat age-related diseases.

Oceanographers have calibrated and processed data from microplastic sampling expeditions to build a publicly available dataset for more accurately assessing the abundance of microplastics—and their long-term trends—in the world’s oceans.
