An intrinsically photosensitive retinal ganglion cell (ipRGC) as it would appear if you looked at a mouse's retina through the pupil. The white arrows point to the many different types of cells with which it networks: other subtypes of ipRGCs (red, blue and green) and retinal cells that are not ipRGCs (red). The white bar measures 50 microns.

Two-photon imaging helps make discovery about light-sensitive cells in baby's retina

A combination of techniques, including two-photon imaging, found that these light-sensitive cells communicate as part of an interconnected network that gives the retina more light sensitivity than once thought.

The TheraLight FIT system for total-body photobiomodulation is shown.

TheraLight adds red light therapy option for total-body photobiomodulation

TheraLight FIT's advanced light therapy technology uses LEDs with both red and infrared wavelengths that enhance the body's ability to heal itself.

Duke University engineers have developed a new type of microscope that uses a bowl studded with LED lights of various colors and lighting schemes produced by machine learning.

Microscope uses machine learning to optimize illumination settings

The microscope adapts its lighting angles, colors, and patterns while teaching itself the optimal settings needed to complete a given diagnostic task.

Methods of extracting features from label-free immune cell analysis are shown: Multivariate label-free data, composed of both morphological and spectral parameters, are used to identify high-level features at the single-cell level such as cellular type, response to drugs, as well as response differences between specimens.

Label-free multimodal imaging system distinguishes between cell types

The label-free multimodal imaging platform enables the study of cell cultures noninvasively without the need of any contrast agent.

Shown is a representation of the tapered optical fiber able to detect optical signals from different neurons simultaneously.

Tapered optical probe helps detect light in the brain

The new method allows the simultaneous collection of signals from various brain regions through the use of a tapered optical probe.

Fluorescent gel is applied to the mouth of a vampire bat in a rural area near Lima, Peru, to test the potential effectiveness of a 'spreadable' rabies vaccine. The bright red gel causes bat hair follicles to fluoresce under the microscope, so that researchers can track the spread of the biomarker through the bat population.

Fluorescent gel used in vampire bats could be effective rabies control

The fluorescent gel was applied to wild vampire bats at three colonies in Peru, where it simulated the bat-to-bat spread of an orotopical rabies vaccine.

Researchers used a new endoscopic OCT system to visualize variances in pig cartilage thickness; the image shows a sketch of a femur and processed OCT images with thin regions shown in dark red and thicker regions more yellow and white (scale bar = 250 µm).

Endoscopic OCT system could have use in minimally invasive joint surgery

The work is promising for bringing OCT imaging to new surgical and medical applications.

Endeavor Business Media acquires Informa’s Industry & Infrastructure Intelligence and Auto Aftermarket media brands

This latest acquisition continues to expand Endeavor’s position as one of the largest B2B companies.

Deep learning converts 2D fluorescence microscopy images into 3D

Using a deep learning approach, researchers improved upon fluorescence microscopy to turn 2D images into stacks of virtual 3D slices showing activity inside organisms.
