If an infection goes too far, a patient can develop sepsis, an inflammatory response that spreads throughout the body and can endanger a patient's life. And although it's fairly common, accounting for 20 to 30 percent of all hospital deaths every year, doctors and nurses have a hard time identifying sepsis before it's too late to treat. Now researchers from Johns Hopkins University have created software that can predict which patients are most at risk for sepsis using information collected by their bedside monitoring devices during their hospital stay, which could save many thousands of lives per year. The research was published today in Science Translational Medicine.
Involuntary muscle twitches are exceedingly common and yet not very well understood. "Nearly everyone experiences it," Dr. Daniel Drachman, professor of neurology and neuroscience at Johns Hopkins University, told me. "It occurs spontaneously in well over 90 percent of people at one time or another." Right now, as I write this sentence, it's happening to me. My left eyelid is twitching uncontrollably. It is very annoying.
Neither bio-mimicking robots nor insect-analog micro aerial vehicles (MAVs) are new concepts. But where super high-speed video capture, competitive figure skating, and lepidopterology collide, there PopSci shall be. Today, that means turning our attention to Johns Hopkins University, where engineering undergrad Tiras Lin is potentially shaking up insect-like aerial robot design.
As the calendar turns over to a new year, a couple of researchers over at Johns Hopkins University are rethinking the way we tick off the days during our annual trip around the sun. The duo has devised a new yearly calendar in which each 12-month period is identical to the one before - meaning if your birthday is on a Monday one year, it's on a Monday every year - until the end of time.
When a satellite becomes unresponsive in orbit, there's not much to be done - engineers can try in vain to hail the spacecraft and send it instructions, or perhaps blow it up in a show of bravado. But fixing it is pretty much out of the question, especially now that the space shuttle is retired.But what if a remotely operated robot could do the job? Engineers at Johns Hopkins University have been working with a da Vinci surgical robot in a test of long-distance mechanical repair - call it satellite surgery
