Anthropic published research describing how it designs memory systems for Claude-based agents, drawing an analogy to human memory consolidation during sleep. The approach, built on work from Letta and UC Berkeley researchers on 'sleep-time compute,' has agents reorganize logs and transcripts during idle periods to fix errors, write notes, and build new memory representations for future sessions.
Amazon is selling the Oura Ring 4 Smart Ring in Ceramic Midnight for $279, down from its $399 list price, a 30% discount that matches the lowest price it has ever hit. The ring tracks sleep, recovery, activity, heart rate, temperature and stress without a screen, using Oura's Smart Sensing technology, and the ceramic version is built from scratch-resistant zirconia ceramic with a battery life of roughly 5 to 8 days.
Samsung announced that its Galaxy Ring and Galaxy Watch devices received FDA approval in July for an upgraded sleep apnea detection feature. The AI-powered tool now tracks breathing disruptions hourly and can report mild, occasional or frequent apnea after users log at least five hours of sleep on two nights within a ten-day span. The feature is also rolling out to the Galaxy Watch 9, with Watch 7 and 8 support planned via future updates.
Samsung has begun rolling out an improved sleep apnea detection feature to the Galaxy Watch 9, Galaxy Watch Ultra 2, and Galaxy Ring in the US and South Korea. The update follows clearances from the FDA and South Korea's MFDS, and arrives through the Samsung Health Monitor app. Instead of a simple yes/no result, the algorithm now tracks blood oxygen drops and breathing disruptions across two sleep sessions within a 10-day window to gauge severity.
Samsung is rolling out an upgraded sleep apnea detection feature powered by a new AI algorithm, offering more detailed reports that classify severity as mild, occasional, or frequent. The feature launches in Korea in November for the Galaxy Watch Ultra 2, Watch 9, and Galaxy Ring, with Watch 7 and 8 getting it via future software updates, though a US release date hasn't been confirmed.
A new feature examines how consumers are increasingly using wearable devices such as sleep trackers, smartwatches, and over-the-counter continuous glucose monitors to monitor personal health metrics. The piece notes these devices not only collect health data but also provide guidance on how users can act on it.
A new continual-learning method called the Sleep framework uses two stages—memory consolidation and dreaming—to help language models retain old knowledge while learning new tasks. Consolidation compresses short-term learning traces into model parameters using on-policy distillation and semantic rewards, while dreaming generates synthetic training examples by randomly activating different mixture-of-experts components and filtering them by gradient-based reward signals.
Amazon unveiled the Echo Time, its first smart alarm clock, priced at $200 and shipping in December. The device features a 3.2-inch customizable display, adaptive lighting for wake and sleep routines, and an optional AI mode that uses motion and breathing sensors to delay or adjust alarms within a 60-minute window based on sleep depth. It omits cameras and comes in kid-focused versions with parental controls, part of a broader rollout that included a new Echo Show, Echo Studio and Amazon's first smart picture frame.
Amazon introduced five new smart home products and a new feature on Wednesday, roughly two weeks after Apple revealed its HomeView display and HomePod Mini 2. The lineup includes Echo Time, a $200 camera-free alarm clock with Alexa Plus-powered sleep tracking and an optional smart alarm that wakes users during light sleep, plus a kids' version called Amazon Kids Echo Time that pairs with parental controls via the Amazon Parent Dashboard.
Samsung has received regulatory clearance from the US FDA and Korea's MFDS for an advanced sleep apnea detection feature on its wearables. The feature uses an AI algorithm to count breathing disturbances per hour during sleep and categorizes results as mild, occasional, or frequent. It will roll out in November to the Galaxy Watch Ultra 2, Watch 9, and Galaxy Ring in South Korea, with older models like the Watch 8 and Watch 7 to follow via software updates.
Amazon has begun shipping most of the new Echo devices it recently announced, among them a bedside alarm clock built around sleep tracking rather than a camera. The device uses ultrasound to detect sleep stages and can trigger smart alarms timed to ease users awake, an optional feature users can turn off.
Amazon unveiled the Echo Time, a new smart alarm clock with a 3.2-inch round touchscreen and a sleep-sensing feature designed to wake users during an optimal point in their sleep cycle. The device, priced at $199.99 and available for order now, lets users set alarms directly via touchscreen rather than voice, and keeps the clock face visible as a priority display even while handling other Alexa functions.
