Organized by... -
Audio/PodcastDisruptive: Molecular RoboticsHow can DNA be programmed to build novel structures, devices, and robots? We have taken our understanding of DNA to another level, beginning to take advantage of some of DNA’s properties that have served nature so well, but in ways nature itself may have never pursued. Humans can now use DNA as a medium for... -
Video/AnimationSmall Airway-on-a-Chip: Modeling COPD and AsthmaDevelopment of new therapeutics for chronic lung diseases have been hindered by the inability to study them in vitro. To address this challenge, Wyss Institute researchers used their Organ-on-a-Chip technology to produce a microfluidic ‘human lung small airway-on-a-chip.’ The device, which is composed a clear rubber material, is lined by living Human lung small airway... -
Audio/PodcastDisruptive: Cancer Vaccine & Hydrogel Drug DeliveryIn this episode of Disruptive, Wyss Founding Core Faculty Member Dave Mooney discusses programmable nanomaterials approaches to fighting disease. Mooney explains how a cancer vaccine, developed by his team and currently in a clinical trial at the Dana-Farber Cancer Institute, can train one’s own immune system to target specific cancer cells. He also describes the... -
Video/AnimationCircadian TransplantThe first successful transplant of a circadian rhythm into a naturally non-circadian species could lead to precisely timed release of drugs and other innovative therapeutic applications. In this video, gut bacteria (E. coli) exhibit a circadian rhythm after circadian oscillators were transferred from cyanobacteria. The ‘mother cell’ at the top blinks on and off with... -
Audio/PodcastDisruptive: Synthetic BiologyWhat sorts of breakthroughs are possible by modifying an organism’s genome – something researchers are now able to do ever more cheaply and efficiently? Researchers around the world are already able to program microbes to treat waste water, generate electricity, manufacture jet fuel, create hemoglobin, and fabricate new drugs. What sounds like science fiction to... -
Video/AnimationHuman Organs-On-ChipsWyss Institute researchers and a multidisciplinary team of collaborators have engineered microchips that recapitulate the microarchitecture and functions of living human organs, including the lung, intestine, kidney, skin, bone marrow and blood-brain barrier.
