In APL Bioengineering, researchers create a biomimetic model to study wound healing in burn and laceration wounds. The team designed an in vitro model system made of fibroblasts embedded in a collagen hydrogel. Wounds were created in this microtissue using a microdissection knife to mimic laceration or a high-energy laser to simulate a burn. They discovered that fibroblasts clear away damaged tissue before depositing new material. This part of the healing process is slower in burn wounds.

Society for Laboratory Automation and Screening Announces $100,000 Graduate Education Fellowship Grant Awarded to David McIntyre of Boston University
The Society for Laboratory Automation and Screening (SLAS) is pleased to announce David McIntyre, Ph.D. candidate from Boston University (Boston, MA, USA), as the 2021 SLAS Graduate Education Fellowship Grant recipient.
New Insights into Wound Healing Process
Biomedical engineers developed a technique to observe wound healing in real time, discovering a central role for cells known as fibroblasts. The work, reported in APL Bioengineering, is the first demonstration of a wound closure model within human vascularized tissue in a petri dish.
How Does Eye Position Affect ‘Cocktail Party’ Listening?
Several acoustic studies have shown that the position of your eyes determines where your visual spatial attention is directed, which automatically influences your auditory spatial attention. Researchers are currently exploring its impact on speech intelligibility. During the 179th ASA Meeting, Virginia Best will describe her work to determine whether there is a measurable effect of eye position within cocktail party listening situations.
