An anonymous reader quotes a report from The New York Times: The last time Anthony Aiello spoke to his stepdaughter, he took homemade pizza and biscotti to her house in San Jose, Calif., for a brief visit. Mr. Aiello, 90, told investigators that she then walked him to the door and handed him two roses in gratitude. But an unnoticed observer in the house later revealed that their encounter ended in murder, a police report said. Five days afterward, Mr. Aiello's stepdaughter, Karen Navarra, 67, was discovered by a co-worker in her house with fatal lacerations on her head and neck. She had been wearing a Fitbit fitness tracker, which investigators said showed that her heart rate had spiked significantly around 3:20 p.m. on Sept. 8 (Warning: source may be paywalled; alternative source), when Mr. Aiello was there. Then it recorded her heart rate slowing rapidly, and stopping at 3:28 p.m., about five minutes before Mr. Aiello left the house, the report said. Mr. Aiello was arrested last week on murder charges and booked into the Santa Clara County Jail, the San Jose Police Department said. On Thursday, he will appear in court in the Hall of Justice in San Jose, according to the Santa Clara County district attorney's office. "[T]he police said their investigation used a combination of video surveillance and data from Ms. Navarra's Fitbit, an Alta HR device, which she wore on her left wrist and synchronized with a computer in her home, where she lived alone," reports NYT. When asked for comment, Fitbit shared a copy of its privacy policy, stating in part that they comply with legal processes, including search warrants and court orders, when it shares data.

Today, Fitbit announced that it will extend its support of the Pebble smartwatch ecosystem, including devices, software, and forums, until June 30, 2018. "During this time, we invite the Pebble community to explore how familiar highlights from the Pebble ecosystem are evolving on the Fitbit platform, from apps and clock faces to features and experiences," the company's blog post states. Ars Technica reports: Fitbit's invitation is a hopeful one for the company itself. After the buyout, members of the Pebble team helped Fitbit develop its own smartwatch OS that debuted on the $300 Fitbit Ionic last year. Fitbit is likely hoping that diehard members of the Pebble community, many of which developed apps and programs for the smartwatch platform, will try making similar programs for Fitbit's new wearable operating system. The Fitbit SDK is already quite accessible, allowing developers to sign up and start building programs using all-online tools. But in addition to the accessibility of the SDK, Fitbit wants to entice Pebble users with a discount: users with a valid Pebble device serial number can get $50 off a Fitbit Ionic smartwatch. It's currently the only device that runs Fitbit OS, and it's useful to have if you want to test out any apps made with the SDK. But for those who want nothing to do with Fitbit OS development and only care about how long their Pebbles will last, this news is bittersweet. According to Fitbit's announcement, Pebble devices will continue to work after June 30, but these features will stop working: the Pebble app store, the Pebble forum, voice recognition features, SMS and email replies, timeline pins from third-party apps (although calendar pins will still function), and the CloudPebble development tool.

Fitbit has published the results of a study that uses their longitudinal sleep database to analyze millions of nights of Sleep Stages data to determine how age, gender, and duration affect sleep quality. (Sleep Stages is a relatively new Fitbit feature that "uses motion detection and heart rate variability to estimate the amount of time users spend awake in light, deep, and REM sleep each night.") Here are the findings: The average Fitbit user is in bed for 7 hours and 33 minutes but only gets 6 hours and 38 minutes of sleep. The remaining 55 minutes is spent restless or awake. That may seem like a lot, but it's actually pretty common. That said, 6 hours and 38 minutes is still shy of the 7+ hours the the CDC recommends adults get. For the second year in a row Fitbit data scientists found women get about 25 minutes more sleep on average each night compared to men. The percentage of time spent in each sleep stage was also similar -- until you factor in age. Fitbit data shows that men get a slightly higher percentage of deep sleep than women until around age 55 when women take the lead. Women win when it comes to REM, logging an average of 10 more minutes per night than men. Although women tend to average more REM than men over the course of their lifetime, the gap appears to widen around age 50.

WearDuino, now being developed by PDX Wearable Health Lab, is the brainchild of Mark Leavitt, MD, PhD; "an experimenter, maker, mentor and consultant in wearable health technologies, drawing on his lifelong experience in the fields of engineering and medicine." The WearDuino, he says, "is an open source wearable wireless sensor." The prototype fits in a FitBit case because, according to Dr. Leavitt, there are millions of unused ones out there, both surplussed by people who bought Fitbits and then stopped using them, and in the form of aftermarket cases sold to make your Fitbit cuter than when it came from the factory. In any case, WearDuino is still in the prototype stage. Dr. Leavitt plans to look for funding through Crowd Supply, but isn't "there" yet, so if you want to get on board with this health wearables project, you'll want to sign up for their Google Group or follow them on Twitter. You might also want to check out Quantified Self (tag line: "self knowledge through numbers"), and even if you vastly prefer videos to text articles, check out the text transcript ("Show/Hide Transcript") attached to this article, because it contains nearly twice as much information as the video, and goes a little deeper than the video into Dr. Leavitt's reasons for building the WearDuino -- none of which are financial gain, believe it or not.
