With this fluorescence technique, stacks of images are merged to reproduce a live specimen in 3-D. In recent years, light-sheet microscopy (LSM) has come to the fore as a faster, less phototoxic method than other fluorescence microscopy techniques, making it ideal for studying living organisms and the biological processes that take place within them.

Multispectral Quantitative Phase Imaging Captures Live Human Cells Quickly
Within biological systems, structural, chemical and functional information about a system of interest can be extracted from the wealth of spectral data available. This article focuses on the specific application of multispectral imaging to quantitative phase imaging – specifically, the known chromatic aberration from sequential images obtained from a high-speed multispectral wheel camera yield a quantitative phase, facilitating cell tracking and screening.

Chemotherapeutic drugs have long held their own in the fight against cancer, but inefficiency in delivery and unwanted side effects continue to hinder the process. Now, a team from the University at Buffalo, with assistance from the University at Albany, Roswell Park Cancer Institute, the University of Waterloo and McMaster University, is developing a new way to deliver these medications.

Optogenetic Switch Now Works Both Ways: On and Off
Since the beginning of optogenetics, the technique has been more effective at switching neurons on than off — but not anymore. Almost a decade ago, Dr. Karl Deisseroth discovered optogenetics, in which light-activated opsins from algae pass electrical current into neurons to control brain circuitry. Recently, his team at Stanford University has re-engineered the light-sensitive proteins to enable more efficient regulation of the cells’ “off” switches.
