Optogenetics is giving scientists a better look at how different parts of the brain can work together to manipulate memories. Using the light-based technique, researchers at the University of California, Davis, have been able to erase specific memories in mice. Their findings prove the basic theory of how different parts of the brain will work together to retrieve episodic memories, they said. The researchers used mice genetically modified to make their nerve cells fluoresce green when activated by light and to make the cells express a protein that allows them to be switched off...Read full articleRelated content from Photonics MediaARTICLES2-Photon Microscopy Shows Learning Involves Various Areas of BrainTo explore how learning and memory-building take place in the brain, scientists at Johns Hopkins University School of Medicine used a laser-assisted imaging tool to monitor and measure levels of...BioPhotonics Mar/Apr 2020 IssueLight-Activated Dynamic Looping Triggers Gene ExpressionUsing a technique called light-activated dynamic looping, or LADL, scientists at the University of Pennsylvania are investigating the role that genome folding plays in gene expression.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookMicroscopy Illumination: Considering Nonlaser Light Sources: Metal halide and LED light sources are changing the illumination landscape in microscopy.
