While time has brought advancements in methods and materials, the basic nature of surgical sutures has not changed since their conception, and their use still poses significant risk of complications to patients. But what if doctors could close tissues without the use of sutures at all?

The COVID-19 pandemic has illustrated how quickly a new pathogen can fundamentally change economies and society. Early in the pandemic, public health professionals demanded quick and accurate testing to track and control the spread of COVID-19 but still struggle to do so using existing testing methods. Two years after its first recorded case, however, researchers at the University of Maryland (UMD) are developing faster, less invasive, and more reliable means of diagnosing pathogens like COVID-19. 

Worldwide, buried dangers lurk: 110 million buried landmines, unexploded ordnance (UXO), and explosive remnants of war (ERWs) result in an annual 10,000 casualties. For every one landmine that is removed, a further 100 are planted, and the process for removal is hazardous, costly, and inefficient.  Over 7000 additional casualties come from construction utility digs in the U.S. from inaccurate maps (accidentally striking a utility being the primary cause).
