The FDA has signaled approval for the Loss of Pulse Detection feature on the Pixel Watch 3.
It detects if the user is experiencing "primary cardiac arrest" or "respiratory or circulatory failure."
Loss of Pulse Detection was previously available in 14 European countries, but will not arrive in the U.S. until late March 2025.
A key draw to the Pixel Watch 3 is its Fitbit-branded health sensors for detecting heart issues. On Wednesday, Google announced that the FDA has given clearance for Loss of Pulse Detection to be used on its smartwatch in the United States, signaling that the feature is accurate enough to be trusted on a consumer device.
As the name implies, Loss of Pulse Detection can "detect when you've experienced a loss of pulse." It will then vibrate with a check-in message before starting an alarm to alert people nearby; if you continue to be unresponsive, it will attempt to call 911 and send an automated message with your location to the emergency responder.
Google heavily advertised this feature when launching the Pixel Watch 3 in September, but while it arrived quickly in 14 countries in the EU and United Kingdom, Google had to get regulatory approval before launching it in the United States. Since this isn't an active feature, many American Watch 3 buyers may have assumed it was available.
Thankfully, Google announced that "we'll begin rolling it out in the U.S. at the end of March," so we won't have too much longer to wait. This feature won't be available on older Pixel Watch models, however.
The Pixel Watch 3 sells in 32 countries, meaning a majority of them still don't have Loss of Pulse Detection. The current list is Austria, Belgium, Denmark, France, Germany, Ireland, Italy, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom; Google claims that "additional countries will be added as regulatory clearance is obtained."
While this feature only becomes necessary in drastic circumstances, the Pixel Watch 3 also has more preventative heart health tools. It has an ECG to detect signs of atrial fibrillation (AFib) during active checks, as well as automatic irregular heart rhythm notifications to catch warning signs throughout the day.
Plus, the Watch 3 can detect if the user experiences a sudden fall or a car crash, with a similar method of calling emergency services if the wearer cannot respond to prompts.
Among Android smartwatches, the Pixel Watch 3 is one of the most accurate when it comes to heart rate data, both generally and during workouts, so we're happy to have this feature arriving for worst-case scenarios. And we're curious what new health features will come to the Pixel Watch 4.

AI leaders have a new term for the fact that their models are not always so intelligent
Progress is rarely linear, and AI is no exception. As academics, independent developers, and the biggest tech companies in the world drive us closer to artificial general intelligence — a still hypothetical form of intelligence that matches human capabilities — they've hit some roadblocks. Many emerging models are prone to hallucinating, misinformation, and simple errors. Google CEO Sundar Pichai referred to this phase of AI as AJI, or "artificial jagged intelligence," on a recent episode of Lex Fridman's podcast. "I don't know who used it first, maybe Karpathy did," Pichai said, referring to deep learning and computer vision specialist Andrej Karpathy, who cofounded OpenAI before leaving last year. AJI is a bit of a metaphor for the trajectory of AI development — jagged, marked at once by sparks of genius and basic mistakes. "You see what they can do and then you can trivially find they make numerical errors or counting R's in strawberry or something, which seems to trip up most models," Pichai said. "I feel like we are in the AJI phase where dramatic progress, some things don't work well, but overall, you're seeing lots of progress." In 2010, when Google DeepMind launched, its team would talk about a 20-year timeline for AGI, Pichai said. Google subsequently acquired DeepMind in 2014. Pichai thinks it'll take a little longer than that, but by 2030, "I would stress it doesn't matter what that definition is because you will have mind-blowing progress on many dimensions." By then the world will also need a clear system for labeling AI-generated content to "distinguish reality," he said. "Progress" is a vague term, but Pichai has spoken at length about the benefits we'll see from AI development. At the UN's Summit of the Future in September 2024, he outlined four specific ways that AI would advance humanity — improving access to knowledge in native languages, accelerating scientific discovery, mitigating climate disaster, and contributing to economic progress.

FAA requires SpaceX to investigate Starship Flight 9 mishap
When you buy through links on our articles, Future and its syndication partners may earn a commission. SpaceX needs to figure out what happened on the ninth test flight of its Starship megarocket, the U.S. Federal Aviation Administration (FAA) has decreed. Flight 9, which lifted off from SpaceX's Starbase site in South Texas on Tuesday (May 27), ended in the destruction of both of Starship's stages — its Super Heavy booster and Ship upper stage (which is also sometimes known, somewhat confusingly, as Starship). But the FAA, which grants launch licenses for U.S. operators, is only concerned about one of those explosive events. "The mishap investigation is focused only on the loss of the Starship vehicle, which did not complete its launch or reentry as planned," FAA officials wrote in an update today (May 30). "The FAA determined that the loss of the Super Heavy booster is covered by one of the approved test induced damage exceptions requested by SpaceX for certain flight events and system components," the agency explained. "The FAA evaluated each exception prior to launch approval and verified they met public safety requirements." SpaceX broke new ground on Flight 9, reusing a Super Heavy for the first time ever. This particular booster first flew on Flight 7 in January, acing its engine burn and then returning to Starbase for a successful and dramatic catch by the launch tower's "chopstick" arms. The company did not attempt another catch on Flight 9. It conducted a variety of experiments with the booster, including bringing it down to Earth on a higher "angle of attack" to increase atmospheric drag. So, for safety's sake, SpaceX steered Super Heavy toward a "hard splashdown" in the Gulf of Mexico on Tuesday. This didn't quite work out, however. "Contact with the booster was lost shortly after the start of landing burn when it experienced a rapid unscheduled disassembly approximately 6 minutes after launch, bringing an end to the first reflight of a Super Heavy booster," SpaceX wrote in a Flight 9 recap. Ship had an even harder time on Flight 9. The upper stage was supposed to make a soft splashdown in the Indian Ocean off the coast of Western Australia about 65 minutes after launch, but it suffered an "attitude control error" that prevented the vehicle from getting into the proper orientation for reentry. "Starship then went through an automated safing process to vent the remaining pressure to place the vehicle in the safest condition for reentry," SpaceX wrote in the recap. "Contact with Starship was lost approximately 46 minutes into the flight, with all debris expected to fall within the planned hazard area in the Indian Ocean." Related stories: — SpaceX reached space with Starship Flight 9 launch, then lost control of its giant spaceship (video) — Starship and Super Heavy explained — SpaceX loses Starship rocket stage again, but catches giant Super Heavy booster during Flight 8 launch (video) This was still a considerable improvement over Ship's performance on its previous two liftoffs. On both Flight 7 and Flight 8 (which launched in March), Ship was lost less than 10 minutes after liftoff, raining debris down over the Atlantic. There have been no reports of injuries or damage to public property as a result of the Flight 9 mishap, according to the FAA. There were also minimal effects on flights in U.S. airspace — an improvement over the previous two Starship launches. "The FAA activated a Debris Response Area, out of an abundance of caution, when the Super Heavy booster experienced its anomaly over the Gulf of America during its flyback toward Texas," FAA officials wrote. "The FAA subsequently determined the debris did not fall outside of the hazard area," they added. "During the event, there were zero departure delays, one flight was diverted, and one airborne flight was held for 24 minutes."

Food recall: Brown eggs sold at grocery stores across California have salmonella risk
A California company is recalling 1.7 million cartons of brown eggs — sold at stores including Walmart in nine states including California — because the eggs may be contaminated with salmonella bacteria. August Egg Company of Hilmar is recalling 1,700,000 dozen brown cage-free and brown certified organic eggs for potential salmonella risk. The eggs were distributed over the last four months, some with sell by dates as late as June 19, according to the recall notice from the Food and Drug Administration. The eggs are linked to an ongoing Salmonella Enteritidis outbreak in seven states, in which 79 people have been sickened and at least 21 hospitalized, but no deaths have been reported, according to the Centers for Disease Control and Prevention. Most of the people sickened (63) live in California, according to the CDC. Nevada and Washington reported four illnesses each, with additional cases in Arizona (3), New Jersey (2), Nebraska (2), Kentucky (1). Ill people in Kentucky, New Jersey, and Washington reported traveling to California and Nevada before they got sick. Most of those sickened (90%) reported eating eggs, the CDC said. Some samples taken by the FDA during an inspection at August Egg Company's processing facility tested positive for the strain of salmonella similar to those related to the persons sickened in the outbreak, the CDC said. August Egg Co. said its internal food safety team is conducting its own investigation to "identify what measures can be established to prevent this situation from recurring," the company said in a statement accompanying the recall. 'It is important to know that when our processing plant identified this concern, we immediately began diverting all eggs from the plant to an egg-breaking facility, which pasteurizes the eggs and kills any pathogens." USA TODAY Recall Database: Search vehicle, product and food recalls The recalled eggs were distributed beginning Feb. 3 across multiple retailers in nine states: Eggs with sell-by dates to June 4: Through May 15, eggs with those sell-by dates were distributed to Save Mart, FoodMaxx, Lucky, Smart & Final, Safeway, Raleys, Food 4 Less and Ralphs stores in California and Nevada. Eggs with sell-by dates to June 19: Through May 6, eggs with those sell-by dates were distributed to Walmart locations in California, Washington, Nevada, Arizona, Wyoming, New Mexico, Nebraska, Indiana and Illinois. August Egg Co. said consumers can identify the recalled eggs by the plant code on one side of the egg carton. They can return the eggs to the place of purchase for a refund. Consumers with questions can call the company at 1-800-710-2554, between 9 a.m. and 5 p.m. PT. Here's the products recalled with plant code and UPC. Salmonella causes about 1.35 million illnesses, 26,500 hospitalizations, and 420 deaths each year in the U.S., according to the CDC and FDA. Symptoms of salmonella infection – including diarrhea, fever and stomach cramps – typically arise six hours to six days after exposure and may last 4 to 7 days. Severe infections can also include aches, headaches, elevated fever, lethargy, rashes, and blood in the urine or stool. Salmonella poisoning, also known as salmonellosis, is a common gastrointestinal infection in California, with about 5,000 confirmed cases annually, according to the California Department of Public Health. The Centers for Disease Control estimates that around 3,000 people die from a foodborne illness, and of those about 420 people die from Salmonella infections.
