Scientists have built an app that gives a smartphone the ability to detect an opioid overdose and alert others for help. The app, called Second Chances, is still in development, but the researchers hope to have it approved by the US Food and Drug Administration and eventually sell the technology. With over 110 Americans dying each day from opioid overdoses, the opioid epidemic is the deadliest drug overdose crisis in US history. “It’s a huge public health problem and also one where the diagnostic signs and mechanisms of how people die is really well-established,” says Jacob Sunshine, an anesthesiologist at the University of Washington and co-author of the Second Chances study, which was published this week in the journal Science Translational Medicine. In other words, when people overdose, their breathing changes in a specific and predictable pattern. Second Chances uses sonar technology to detect these changes and alert a friend, relative, or doctor who can then … [Read more...] about New smartphone app can detect overdoses and call for help

Parents usually develop a myriad of ways to calm their crying baby, some more effective than others. With the same aim in mind, Honda’s R&D team recently took time out to create the Sound Sitter, a cuddly toy car with a speaker inside that emits the sound of one of its car engines. Researchers at the automaker claim that the sound waves a baby hears inside the womb aren’t so different from those created by the roaring noises of a car engine. Really. To give the Sound Sitter the best possible chance of encouraging a screaming baby to calm down and nod off, the Japanese company tested the sound of no less than 37 engines manufactured for various Honda models over the last 50-plus years. Testing the engine sounds with 12 infants aged between six months and 1.5 years, the most effective one visibly calmed 11 of the babies in a short space of time, with 7 of them showing reduced heart rates. The engine powers the Acura NSX, Honda’s $156,000 supercar. Being a supercar, … [Read more...] about Honda’s app-controlled ‘Sound Sitter’ uses engine noise to calm down kids
