The combination of laser poration and microelectrode arrays (MEA) allows action potential-like recordings of cultivated primary and stem cell-derived cardiomyocytes. The waveform shape provides superior insight into test compounds' mode of action than standard recordings. It links patch-clamp and MEA readout to further optimize cardio safety research in the future.

Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...

We describe a technique to label neurons and their processes via anterograde or retrograde tracer injections into brain nuclei using an in vitro preparation. We modified an existing method of in vitro tracer electroporation by taking advantage of fluorescently labeled mouse mutants and basic optical equipment in order to increase labeling accuracy.

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
FAQs
The filters target the laser wavelengths used in the experiment by absorbing or reflecting selected optical energy. Their optical density determines how strongly transmission is reduced, helping limit the amount of radiation reaching the eye below injury thresholds. This wavelength-dependent action is why eyewear must be matched to the laser rather than selected as a general-purpose visual shield.
Wavelength identifies which laser radiation the eyewear is designed to attenuate, while power and operating mode affect the exposure conditions that the goggles must manage. Selecting protection with sufficient optical density for these factors helps reduce hazardous energy at the eye. In neuroscience setups, this matching supports protection during different focused-light operating conditions.
A suitable filter reduces selected laser energy while preserving appropriate visibility for laboratory tasks. That balance matters because researchers must continue positioning equipment, monitoring experiments, or performing other work while protection is in place. The need is especially important when neuroscience experiments use intense or invisible beams, which may not provide a clear visual warning of exposure.
They are relevant to experiments involving focused light, including optogenetics, laser stimulation, and microscopy. These applications can place researchers near intense or invisible beams, making wavelength-matched eye protection an important part of laboratory practice. The goggles support work across procedures in which light is directed precisely at neural preparations, samples, or imaging targets.
Selection should account for the laser wavelength, its power, and the operating mode, then confirm that the eyewear provides appropriate optical density for those conditions. Researchers should also ensure that the goggles preserve enough visibility for the planned laboratory tasks. Matching these characteristics to the setup helps limit exposure and supports consistent, safe experimental work.
Appropriately selected eyewear helps reduce the possibility that hazardous laser radiation reaches the eyes at levels associated with injury thresholds. This is relevant to preventing retinal or corneal damage during neuroscience experiments. By incorporating protection into work with optogenetics, stimulation, microscopy, and other focused-light procedures, laboratories can also support safer and more reproducible research practices.
