Light Microscopy – News and Features

Cornell researchers found that psilocybin’s therapeutic benefits depend on the pyramidal tract neurons and the serotonin 5-HT2A receptor in the medial frontal cortex. Targeting these mechanisms could allow psilocybin to treat depression.

For the first time, researchers have imaged living cells and capillaries inside whole organs, offering insights into how living cells behave and opportunities for diagnostics.

Around 50–90% of brain tumor patients that survive at least 6 months after radiotherapy experience some form of cognitive decline, such as memory loss. In a systematic review, we examined damage to the normal brain tissue after brain irradiation.

Researchers have developed a new method for environmental monitoring, based on near-infrared (NIR) light. The technique provides users with real-time spectral information from various materials and biological samples.

Scientists at HHMI’s Janelia Research Campus developed cycleHCR, an imaging tool using DNA barcodes to track RNA and protein molecules in 3D tissues. The technique enables deep tissue imaging of hundreds of molecular targets.

A new approach to monitoring molecular processes deep in tissues could accelerate personalized medicine, cancer diagnostics and disease detection.

An AI-enabled device could make flow cytometry affordable and accessible, reports a new study from Rice University.

New research has found that manufactured separation materials don’t function as intended, uncovering how to improve the process.

Prokaryotes are unicellular organisms that lack membrane-bound structures. This article details the structure of prokaryotic cells and provides examples of prokaryotic organisms.

New research suggests that silver nanoparticles can leach out of antimicrobial plastic packaging and contaminate solid foods.
