New devices to test retinal cells

Researchers at Utah State University have developed new devices to mechanically stress human cells in the lab. In a study published in Lab on a Chip, researchers Elizabeth Vargis, a USU assistant professor of biological engineering and Farhad Farjood, a Ph.D. student in Vargis’ Lab, wanted to better understand the triggers of age-related macular degeneration

New micro-platform reveals cancer cells’ natural behavior

A new cell culture platform allows researchers to observe never-before-seen behaviors of live cancer cells under the microscope, leading to explanations of long-known cancer characteristics. The easy-to-produce platform developed by Hokkaido University researchers offers cancer cells micro-scale attachment sites that elicit never-before-seen behaviors highly relevant to cancer’s clinical properties. The observation of these behaviors shed

A 3-D model of a human heart ventricle: Bioengineers build a scale model of a heart ventricle that beats, survives for months in the lab

Harvard University researchers have bioengineered a three-dimensional model of a human left heart ventricle that could be used to study diseases, test drugs and develop patient-specific treatments for heart conditions such as arrhythmia. The tissue is engineered with a nanofiber scaffold seeded with human heart cells. The scaffold acts like a 3D template, guiding the

Flexible, highly efficient multimodal energy harvesting

A 10-fold increase in the ability to harvest mechanical and thermal energy over standard piezoelectric composites may be possible using a piezoelectric ceramic foam supported by a flexible polymer support, according to Penn State researchers. In the search for ways to harvest small amounts of energy to run mobile electronic devices or sensors for health
