RFK Jr. Announces All Americans Need Health Tracking Devices: Here Are the Pros and Cons

The US Health Secretary plans a huge campaign to encourage health wearables: CNET knows exactly the kind of devices he’s talking about, and why accuracy may be a problem.

Many Americans already track health statistics like heart rate and sleep cycles on app-connected accessories. Now the federal government wants to jump in. On June 24, Health Secretary Robert F. Kennedy Jr. announced «one of the largest HHS campaigns in history» to encourage the use of wearables to track health conditions, a trend CNET has recently covered.

Kennedy is referring to the many different bands, watches and even clothes that use technology to track human vital signs. CNET’s reviewers have spent years testing devices like these, seeing how rings monitor health signs, straps track your heart health and the right devices lead to better sleep.

The latest version of the Apple Watch, for example, has sensors designed to detect heart rate, heart rhythm issues, falls, sleep health, sleep apnea, temperature, breathing rate and more. The newest Oura Ring can track sleep patterns, menstrual cycles, temperature, heart rate and other health details.

«We think that wearables are a key to the MAHA agenda, Making America Healthy Again ,» Kennedy told the Subcommittee on Health during its budget meeting. «My vision is that every American is wearing a wearable within four years … they can see what food is doing to their glucose levels, their heart rates and a number of other metrics as they eat it.»

Kennedy also tweeted that «wearables put the power of health back in the hands of the American people.»

«Wearables,» however, is a broad term encompassing everything from fitness devices that count steps to sleep trackers you wear at night. And consumer devices can’t easily replace monitoring solutions offered by medical professionals.

For example, CNET has covered research indicating that even the best-in-class Apple Watch struggles with accuracy from metrics like steps to heart rate. Another study from California State Polytechnic University has shown that fitness-related Fitbit trackers show high inaccuracies as well. In fact, that research was used in a related Fitbit lawsuit.

Speaking of glucose monitors, Kennedy isn’t the only White House official with an interest in such health sensors. The administration’s nominee for surgeon general, Dr. Casey Means, co-founded glucose-monitoring company Levels and sells a monitoring app as well as other wellness products.

Finally, CNET wellness experts remind everyone that wearables aren’t always a good fit. Those suffering from eating disorders or body image issues should always talk to an expert before using wearables, as they can exacerbate certain issues or lead to a unhelpful outlook.

The US Department of Health and Human Services did not immediately respond to a request for comment.

AI Toys Can Pose Safety Concerns for Children, New Study Suggests Caution

When one child told the toy, «I love you,» it responded, «As a friendly reminder, please ensure interactions adhere to the guidelines provided.»

A new study from the University of Cambridge found that AI-enabled toys for young children can misinterpret emotional cues and are ineffective at supporting critical developmental play. The conclusions could be concerning for parents.

In one report examining how AI affects children in their early years, a chatbot-enabled toy struggled to recognize social cues during playtime. Researchers found that the toy did not effectively identify children’s emotions, raising alarm about how kids might interact with it.

The report recommends regulating AI toys for kids and requiring clear labeling of their capabilities and privacy policies. It also advises parents to keep these devices in shared spaces where kids can be monitored while playing.

The research behind the study had a limited number of participants, but was done in multiple parts: an online survey of 39 participants with kids in their earlier years, a focus group with nine participants who work with young children and an in-person workshop with 19 leaders and representatives from charities that work with early-years kids. That was followed by monitored playtime with 14 children and 11 parents or guardians with Gabbo, a chatbot-enabled toy from Curio Interactive.

Some findings indicated that the AI toy supported learning, particularly in language and communication skills. But the toy also misunderstood kids and sometimes responded inappropriately to emotional requests.

For instance, when one child told the toy, «I love you,» it responded, «As a friendly reminder, please ensure interactions adhere to the guidelines provided. Let me know how you would like to proceed,» according to the research.

Jenny Gibson, a professor of neurodiversity and developmental psychology at the Faculty of Education at Cambridge, who worked on the study, said that while parents may be excited about the educational benefits of new technology aimed at children, there are plenty of concerns.

Gibson posed overarching questions about the reason behind the tech.

«What would motivate [tech investors] to do the right thing by children … to put children ahead of profits? she said»

Gibson told CNET that while researchers are exploring the potential benefits of AI-based toys, risks remain.

«I would advise parents to take that seriously at this stage,» she said.

What’s next for AI toys

As more playthings are enabled with internet connectivity and AI features, these devices could become a major safety risk for children, especially if they replace real human connections or if interactions are not closely monitored.

Meanwhile, younger people are increasingly adopting chatbots such as ChatGPT, despite red flags. Multiple lawsuits against AI companies allege that AI companions or assistants can impact young people’s psychological safety, including some chatbots that have encouraged self-harm or negative self-image.

AI companies such as OpenAI and Google have responded by adding guardrails and restrictions for AI chatbots.

(Disclosure: Ziff Davis, CNET’s parent company, in 2025 filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Gibson said she was surprised by the enthusiasm some parents showed for AI toys. She was also alarmed by the lack of research on AI’s effects on young children, noting that companies making such products should work directly with children, parents, and child development experts.

«What’s missing in the process is that expertise of what is good for children in these kinds of interactions,» she said.

Curio Interactive, the company behind the Gabbo toy, was aware of the research as it was happening but was not directly involved, Gibson said. The toy was chosen because it’s directly marketed to young kids, and the company had an understandable privacy policy. Gibson said the company seemed supportive of the project.

A representative for Curio did not immediately respond to a request for comment.

Two Lost ‘Doctor Who’ Episodes Found Intact in Waterlogged Collection

The 1960s episodes featuring the first Doctor William Hartnell will air in the UK in April.

Whovians, rejoice. The BBC is about to unlock a piece of Doctor Who history that even the TARDIS might have forgotten. Two lost episodes of Doctor Who, the iconic sci-fi series, will broadcast in April, the showrunner for the current season confirmed.

The two 1965 episodes, The Nightmare Begins and Devil’s Planet, were donated to the charitable trust Film Is Fabulous by the estate of an anonymous collector.

«The collector did recognize what he had, but how he acquired them has been lost to time,» Professor Justin Smith Leicester of De Montfort University, who led the recovery effort, told the broadcaster.

The researchers said that while most of the donor’s private collection was destroyed by water damage, the Doctor Who episodes were intact.

Doctor Who showrunner, Russell T Davies, celebrated the news on Instagram and said the episodes would air in the UK in April, though no US air date has been announced yet.

«Lost for 61 years! Best of all, these will be made available for FREE on the BBC iPlayer in April,» Davies wrote.

He expressed gratitude to Film Is Fabulous for finding the lost episodes and encouraged people to donate to the registered charity. «Maybe they’ll find more! As the Doctor says… ‘Daleks!'»

The episodes feature the first incarnation of the Doctor, played by William Hartnell, and a typical Dalek plot to take over Earth and the galaxy.

In the 1960s and 1970s, the BBC had a policy of destroying film or reusing videotapes, leading to dozens of episodes of Doctor Who and other popular UK shows like Dad’s Army and Top of the Pops going missing.

Old Doctor Who episodes do surface occasionally, and in 2016, the newly discovered soundtrack for one storyline was turned into an animated series called The Power of the Daleks.

Meanwhile, Disney ended its working relationship with the BBC last year, and star Ncuti Gatwa left the show. However, the UK broadcaster says that Doctor Who will continue, and Russell T Davies is working on a new Christmas special.
