Cool Image: Snap-Together Laboratory

Modular microfluidics system. Credit: University of Southern California Viterbi School of Engineering. Like snapping Lego blocks together to build a fanciful space station, scientists have developed a new way to assemble a microfluidics system, a sophisticated laboratory tool for manipulating small volumes of fluids. Microfluidics systems are used by scientists to perform tasks as diverse …

Cool Image: Of Surfaces and Stem Cells

Stem cells grown on a soft surface begin to transform into neurons. Credit: Kiessling Lab, University of Wisconsin-Madison. If you think this image looks like the fluorescent outline of a brain, you’re on the right track. The green threads show neurons that have just formed from unspecialized cells called stem cells. Researchers led by Laura …

Cool Image: Training Cells to Devour Dying Neighbors

A healthy cell (green) that has ingested dying cells (purple). Credit: Toru Komatsu, University of Tokyo. In this image, a healthy cell (green) has engulfed a number of dying cells (purple) just as a predator might ingest wounded or dying prey. A team of researchers is hoping to use this same strategy at the cellular …

Cool Image: Outsourcing Cellular Housekeeping

This image shows the mouse optic nerve and retina. Credit: Keunyoung Kim, Thomas Deerinck and Mark Ellisman, National Center for Microscopy and Imaging Research , UC San Diego. In this image, the optic nerve (left) leaves the back of the retina (right). Where the retina meets the optic nerve, visual information begins its journey from …

Cool Image: Researching Regeneration in a Model Organism

The feeding tube, or pharynx, of a planarian worm with cilia shown in red and muscle fibers shown in green. Credit: Carrie Adler/Stowers Institute for Medical Research. This rainbow-hued image shows the isolated feeding tube, or pharynx, of a tiny freshwater flatworm called a planarian, with the hairlike cilia in red and muscle fibers in …

Cool Image: Lighting up Brain Cells

Neurons activated with red or blue light using algae-derived opsins. Credit: Yasunobu Murata/McGovern Institute for Brain Research at MIT. The nerve cells, or neurons, lit up in blue and red in this image of mouse brain tissue are expressing algae-derived, light-sensitive proteins called opsins. To control neurons with light, scientists engineer the cells to produce …

Cool Image: Denying Microbial Moochers

Productive V. cholerae (yellow) and exploitive V. cholerae (red). Credit: Carey Nadell, Princeton University. What looks like an abstract oil painting is actually an image of several cholera-causing V. cholerae bacterial communities. These communities, called biofilms, include productive and exploitive microbial members. The industrious bacteria (yellow) tend to thrive in denser biofilms (top) while moochers …

Cool Image: Visualizing Viral Activity

Viral RNA (red) in an RSV-infected cell. Credit: Eric Alonas and Philip Santangelo, Georgia Institute of Technology and Emory University. What looks like a colorful pattern produced as light enters a kaleidoscope is an image of a cell infected with respiratory syncytial virus (RSV) illuminated by a new imaging technology. Although relatively harmless in most children, RSV …
