What Are Microfluidic Devices? (Synthetic Biology's Secret Weapon)
Microfluidic devices are like circuit boards for biology, allowing liquids containing different chemical signals to combine in an automated fashion for fast, cheap analyses of everything from COVID-19 tests to DNA sequences. In this video, we go [...]behind the scenes at BU’s Cross-disciplinary Integration of Design Automation Research (CIDAR) lab to see microfluidic devices in action.

This Robot's Soft Gripper Was Inspired By Japanese Kirigami
Boston University mechanical engineers have developed a unique way to use an ancient Japanese art form for a very 21st-century purpose. Douglas Holmes, BU College of Engineering associate professor of mechanical engineering, studies how materials [...]change shape when they are bent or warped by external forces. In a paper published this week in Science Robotics, Holmes and BU PhD student Yi Yang demonstrate how they were inspired by kirigami, the traditional Japanese art of paper cutting (cousin of origami paper-folding art), to design soft robotic grippers.
By cutting sheets of plastic in specific shapes, and then bending them in a specific way, the plastic morphs into a gripper that can safely and securely pick up objects of various size, weight, shape, and fragility. Using the kirigami technique, they’ve developed grippers so small they can pick up a single grain of sand, and large enough to pick up a bottle of water. Holmes and Yang hope that this research will make a significant contribution to the emerging field of soft robotics.

Antiracism in Engineering: Removing "Master/Slave" Terminology
"Master/Slave" terminology is prevalent throughout engineering, from automotive parts to Bluetooth technology. When Santiago Gomez (ENG'22) discovered this, he had to speak out. In this video, Santiago shares his story of how he lobbied for the [...]removal of "master/slave" from Pearson engineering textbooks, and how steps like this need to be taken to chart a course toward truly antiracist education.

Behind the Scenes at BU: Scientific Instrument Facility
In our new series “Behind the Scenes at BU,†we take you to places across campus you might not know exist. First up, a remarkable space hidden behind an unremarkable door in a basement on Cummington Mall. We’re talking about [...]BU’s Scientific Instrument Facility, which produces experimental, cutting-edge hardware to support Boston’s vibrant research community. Founded in 1987, SIF produces cutting-edge, experimental hardware for use in scientific experiments being conducted by researchers here in Boston and across the globe. The shop’s highly skilled technicians build the tools that make discovery possible, from desktop vacuum chambers for use in labs here on campus to components for major research projects like the Dark Energy Spectroscopic Instrument (DESI) at the Kitt Peak National Observatory in Arizona and at the ATLAS experiment at CERN, the European atomic physics laboratory in Geneva, Switzerland.
