Foldscopes: A Swift and Low-Cost Technology Solution to Crop Loss

By Katya Frazier, Ian Kriel, Karen Chien A low-cost and lightweight alternative to the compound microscope, a Foldscope presents an effective way to quickly determine size and viability of pollen and germination. Foldscopes can be used as a tool in agriculture to detect signs of environmental stressors, such as climate change, in which moderate droughts…

3D tumour spheroid models for in vitro therapeutic screening3D tumour spheroid models for in vitro therapeutic screening: a systematic approach to enhance the biological relevance of data obtained.3D tumour spheroid models for in vitro therapeutic screening

By Ian Kriel, Adam Nahor, Kaelyn Coates, and Resa Nelson A map of the earth fails to accurately describe the shape of the planet when compared to a globe. Similarly, 2D cancer cultures fail to capture the scope, morphology, and organisation present in a tumor. Using 3D spheroids to replace 2D cell cultures, dynamics of…

DNA Origami Meets AFM: A Promising Duo in Nanoscience

By: Karen Chen, Kaelyn Coates, and Aloha Das DNA and other similar structures often coil up, obstructing the view of their molecular interactions to researchers. By combining the techniques of AFM (Atomic Force Microscopy) with DNA origami-based scaffolding methods, this paper showcases ways to visualize and study many nanometer-scale common interactions and structures formed by…

Expansion microscopy technique optimized for viewing meiotic protein structures

By Dr. Stefanie Chen By testing three different expansion protocols (ProExM, MAP, and U-ExM) and using three types of super-resolution microscopy (dSTORM, SIM, and re-scan confocal microscopy), researchers were able to determine that MAP-SIM worked best for imaging the fine features of the meiosis-specific synaptonemal complex from mouse spermatocytes. In order to view small molecular…
