The Oura Ring will soon be able to gauge how ‘old’ your heart is

Published

Oura’s been busy this past year launching several new features — and folks with the Gen 3 version of the smart ring are about to get two more. At the end of May, the company will roll out cardiovascular age and cardio capacity metrics for gauging long-term heart health. Emphasis on long-term.

“The thing about cardiovascular age and cardio capacity is that these are both metrics that you can actually impact,” explains Shyamal Patel, Oura’s head of science. Right now, Patel says, Oura’s current feature set has been much more focused on your near-term metrics. “With these features, we’re sort of introducing this idea of longer-term health. What are the things that you’re doing today? How are they contributing to your health in the longer term, your health span, your longevity.”

Oura defines cardiovascular age as how old your vascular system is compared to your chronological age. The smart ring has photoplethysmography (PPG) sensors — the green LEDs that many wearables use to measure heart rate — and from that sensor, it can measure pulse wave velocity to determine arterial stiffness.

The gist is the stiffer your blood vessels, the less efficient your vascular system. Your heart has to work harder, and your organs receive more wear and tear, as stiffer blood vessels can’t adapt as well to changes in blood pressure as more flexible ones can. After about 14 days of tracking, Oura Ring users will get a readout that says whether you’re trending above, below, or in alignment (plus or minus five years) of your chronological age.

The app will also give recommendations on how to improve cardiovascular age or VO2 max.

Oura’s cardio capacity feature may be a bit more familiar to wearable users. Oura Ring owners will be able to take a six-minute test in which they’re prompted to walk as fast as they can. From that test, the ring will give you a VO2 Max estimate.

VO2 Max is a metric that measures your cardiorespiratory health. A higher VO2 Max generally means better performance in endurance sports. As it stands, you’ll usually find this metric highlighted in devices that cater to athletes — like the Whoop 4.0, Garmins, and Polars. Oura’s philosophy for VO2 Max, however, intentionally shifts away from a sports-centric focus.

“Anything that you can do to improve your sort of cardiorespiratory capacity is going to also have long-term health benefits. So for us, the approach is more about giving you a window into what it might mean,” says Patel. For example, the app will tell you what climbing five flights of stairs may feel like in 10 years on your current trajectory, versus one where you improve your VO2 Max.

The timing of these features also can’t be ignored. After years of being the dominant player in the space, the smart ring space is starting to heat up. Most notably, Samsung announced it’ll be launching its first smart ring later this year. Given that, it makes sense that Oura is eager to flex its expertise and reputation for investing heavily in scientific research. (Cardiovascular age, for example, was a passion project of one of its biomedical engineers that took several years of testing and development.) The company also recently launched a labs feature, which allows its users to partake in beta features like early illness detection. Patel says the company has further plans in the pipeline, with more updates planned for 2025.

Correction, May 10th: A previous version of this article called the cardio capacity feature cardiovascular capacity. It has been corrected.

Starlink Mini brings space internet to backpackers

Published

[ad_1]

SpaceX’s Starlink internet-from-space service is already available for boatsplanes, vanlifersAmazonian villages, and rural homes in over 75 countries — now it’s coming to backpackers.

The new compact DC-powered Starlink Mini is about the size of a thick laptop and integrates the Wi-Fi router right inside the dish. And despite using less power than other Starlink terminals, it can still deliver speeds over 100Mbps.

“This product will change the world,” claimed SpaceX CEO Elon Musk on X, saying it took less than five minutes to setup.

Notably, the Mini kit consumes an average of just 20-40W compared to the 33-62W we measured just two years ago with a Standard Actuated dish and separate AC-powered Wi-Fi router. That means you can power the Mini dish for two to three hours from something like an Anker Prime 27,650mAh (99.54Wh) power bank, or a little over an hour with smaller 10,000mAh (40Wh) portable batteries you probably already have laying about. It requires a USB-C PD power source with a minimum rating of 100W (20V/5A). 

The Mini dish measures 11.75 x 10.2 x 1.45 inches (298.5 x 259 x 38.5mm) and weighs just 2.43 pounds (1.1kg), or 3.37 pounds (1.53kg) with the 49.2 foot (15m) DC power cable and kickstand. It has an IP67 rating meaning it’s protected from dust and rain, including short periods of water immersion.

In the US, Starlink Mini is an add-on to Residential plans — at least for now. The Mini kit costs $599 which is $100 more than the standard dish, and will cost an extra $30 per month to add the Mini Roam service to existing $120 Residential plans. That gives Starlink Mini users up to 50GB of mobile data each month, with the option to purchase more for $1 per GB, according to early-access invitations sent to some exiting US Starlink customers. 

While Starlink Mini is new to the US, a Starlink support page says it’s already available in Colombia, El Salvador, Guatemala, and Panama where it can be purchased with Mini Service or Mobile – Regional Service plans. In those countries, there’s no data or speed caps to use Mini, and in-motion and ocean use is not allowed. SpaceX says it’ll expand to more markets over time.

“Our goal is to reduce the price of Starlink, especially for those around the world where connectivity has been unaffordable or completely unavailable,” reads the Starlink support page. “In regions with high usage, like the US, where Starlink Mini places additional demand on the satellite network, we are offering a limited number of the Starlink Mini Kits to start at a higher price point.”

As a standalone service, Starlink Mini could be transformative for anyone in need of an inexpensive and sharable internet service that efficiently sips DC battery power. This includes families that depend upon a cobbled together solar generator for power, a squad of soldiers trying to fight back an invasion, or just bikepackers and overlanders taking the road less traveled.

Elon Musk has another secret child with exec at his brain implant company

Elon Musk, who has long touted claims about the world’s supposed depopulation crisis, had another child with an executive at his brain implant company Neuralink, according to a report from Bloomberg. Neuralink director Shivon Zilis reportedly had the child with Musk earlier this year.

As noted by Bloomberg, Musk has repeated that line several times in the past, including during a 2022 interview with Tucker Carlson and again during an interview at the Milken Institute conference in May. He told Carlson “a collapsing birth rate is the biggest danger civilization faces, by far.” In 2021, Musk’s nonprofit organization donated $10 million to the University of Austin to fund the Population Wellbeing Initiative, a research group that studies the human population.

The revelation also follows multiple reports alleging inappropriate conduct from Musk in the workplace and with subordinates. A recent report from The Wall Street Journal said Musk had a sexual relationship with a former SpaceX intern who later became one of the company’s executives. Another employee says she refused Musk’s requests to have children with him several times, according to the Journal.

Youth plaintiffs in Hawaii reach historic climate deal

Published

A group of young plaintiffs reached a historic climate settlement with the state of Hawaii and Hawaii Department of Transportation in a deal that will push the state to clean up tailpipe pollution.

The 13 youth plaintiffs filed suit in 2022 when they were all between the ages of 9 and 18. In the suit, Navahine F. v. Hawaii Department of Transportation (HDOT), they alleged that the state and HDOT had violated their right to “a clean and healthful environment,” which is enshrined in Hawaii’s constitution.

“We got what we came for, and we got it faster than we expected.”

The settlement, reached on Thursday, affirms that right and commits the DOT to creating a plan to reach zero greenhouse gas emissions from transportation by 2045. To hit that goal, the state will have to dedicate at least $40 million to building out its EV charging network by the end of the decade and complete new pedestrian, bicycle, and transit networks over the next five years. The settlement also creates a new unit within HDOT tasked with coordinating CO2 emission reductions and a volunteer youth council to advise HDOT.

“I am so proud of all the hard work to get us to this historic moment. We got what we came for, and we got it faster than we expected,” the lead plaintiff, Navahine F., said in an emailed statement.

Back in 2018, Hawaii committed to reaching net-zero carbon dioxide emissions by 2045 — in line with what climate research determined was necessary to meet the Paris climate accord goal of stopping global warming. But the state wasn’t doing enough to reach that goal, the plaintiffs alleged. Transportation makes up the biggest chunk of the state’s greenhouse gas pollution.

“Climate change is indisputable,” Ed Sniffen, HDOT director of transportation, said in a press release. “Burying our heads in the sand and making it the next generation’s problem is not pono.”

Youth in Montana scored another historic legal win last year after the first climate case of its kind to go to trial. A state court found that a Montana policy that barred officials from considering the consequences of climate change when permitting new energy projects violated the rights of the plaintiffs to a “clean and healthful environment.” The lawsuit in Hawaii was expected to be the next landmark youth climate case to go to trial in the US. Several other state and federal youth climate suits are still pending in the US.
