Ordinarily, if doctors want to know if a patient's wound is infected, the process takes 24 hours. Unfortunately, a lot can go wrong in that amount of time. Thanks to a new process developed at Washington DC's George Washington University, however, wound infections could soon be detected in less than a minute.
Although any eye injury can be painful and upsetting, those that involve damage to the inside of the eye are the most serious. For people like battlefield medics or rural physicians, however, it can be difficult to judge the extent of such injuries without the resources of a hospital. That's why scientists from the University of Illinois have created OcuCheck – it's a portable sensor that assesses eye injuries based on the amount of vitamin C in the patient's tears.
There's much to be gained from tracking the biomechanics of elite athletes in the lab, where monitoring of stress on joints and muscles can not only aid in performance, but also help prevent injury. Baseball batters and pitchers dealing with one fastball after another are certainly no different, so US company Motus Global has announced an iron-on set of sensors designed to bring this technology out of the lab and onto the field for comprehensive in-match analysis.
In order to treat injured joints, patients are often advised to apply
heat. This typically takes the form of a hot water bottle or
microwavable hot pack (which are cumbersome and cool off) or a heating
pad (which needs to be plugged in). Now, however, scientists from Korea
and the US have created a battery-powered thin mesh that applies heat
and stays put.
