Why parents may want to delay smartphones for kids

NEWYou can now listen to Fox News articles!

Parents everywhere wrestle with one big question. What is the right age to let a child have a smartphone?

Tweens ask for one long before many adults feel ready. At the same time, researchers keep sounding alarms about how early access may shape health and behavior. Now, a large new study gives parents even more to think about.

Published in Pediatrics, the research tracked more than 10,500 children in the national Adolescent Brain Cognitive Development Study. It found strong links between early smartphone ownership and higher odds of depression, obesity and insufficient sleep by age 12. The earlier kids got a phone, the greater their risk.

What the study reveals about early smartphone ownership

The study compared 12-year-olds who owned smartphones with those who did not. Kids with phones were more likely to show signs of depression, carry extra weight and sleep less than their peers without devices. Researchers noted that these patterns held even after accounting for income, neighborhood, parental monitoring and other factors.

They also looked at children who still did not own a phone at age 12. One year later, those who had finally received one showed more mental health concerns and worse sleep than those who still did not have a device. These shifts happened quickly, which raised concerns about how powerful the change can be.

Lead author Dr Ran Barzilay explained that parents should treat the decision like a real health milestone. A device changes how kids sleep, move and socialize. That combination may create more strain for a 12-year-old than for a 16-year-old who has more maturity and self-regulation.

Why age matters more than many parents expect

The research shows an association, not a direct cause. Yet the patterns match earlier findings. Kids with smartphones often stay up later, scroll more and move less. That mix can disrupt physical health and emotional well-being. Adolescence is a sensitive stage when small shifts in sleep or mood can have long-lasting effects.

Experts also pointed out how nearly every teen now has smartphone access. That makes the decision even harder for families who want to delay. Still, researchers say the data is strong enough to guide parents toward waiting when possible. Parents do not need perfect evidence to choose a slower timeline.

Pediatric mental health experts warn that a smartphone is not a simple tool. It opens the entire internet with no natural limits. Families need clear rules and protections and those steps require real work from adults. Many parents feel pressure to hand over a device early, yet the expert urged families to trust their instincts when deciding the timing.

The sleep connection families cannot ignore

Most experts agree that phones disrupt sleep. A large share of preteens keep devices in their bedrooms, which leads to late-night scrolling and overnight notifications. Even the glow of the screen can make it harder to fall asleep.

Researchers who study adolescent sleep and screen habits have found that many 11 to 12-year-olds keep devices within reach at night, and a notable share report being awakened by notifications. Experts in this field urge parents to move phones out of bedrooms overnight because better sleep can reduce some of the risks tied to early smartphone access.

The challenge is consistency. Many parents struggle to set rules when screens support school work, friendships and safety. Yet researchers stress that even one boundary, like no phones in bedrooms, can protect sleep and reduce stress.

How parents can use this information right now

No one wants to shame parents who already gave their kids a phone. Many families made the decision for safety or communication needs. The study does not claim that every early smartphone user will face health issues. It simply highlights patterns worth considering before making the call. Parents can use these insights to create a healthier plan.

1) Delay smartphones until children show readiness

Readiness is more than age. Look for consistent responsibility with chores, schoolwork and device-free rules on other screens.

2) Set clear family rules for screen time

Kids follow rules when they understand why they exist. Set limits that work for your household and adjust them as schedules and needs change.

3) Keep devices out of bedrooms at night

Nighttime use and notifications interrupt sleep. A “charging station” in the kitchen or living room solves this fast.

4) Talk often about online safety and emotional well-being

Short regular check-ins work better than one long conversation. Keep the tone open and supportive.

5) Use parental controls and app limits

Cell phones give parents straightforward tools to manage what kids can see and when they can use their devices.

Small changes make a big difference when kids are still developing the habits that shape their health.

Pro tip: Add device protection

Kids download apps, click links and explore online spaces that can expose them to harmful content or scams. Strong antivirus software adds an extra layer of protection by blocking risky sites and unsafe downloads. It helps keep their device safer while you work on healthy screen habits.

The best way to safeguard your kids’ devices from malicious links that install malware, potentially accessing their private information, is to have strong antivirus software installed on all their devices. This protection can also alert them to phishing emails and ransomware scams, keeping their personal information and digital assets safe.

Kurt’s key takeaways

Smartphones bring connection, opportunity and convenience. They also introduce stress distraction and real health challenges for younger users. Research keeps showing that age matters. A 12-year-old may not be built for the same digital world that a 16-year-old can handle with more confidence and self-control. Families do not need guilt. They need facts and support so they can choose what fits their values. As more data arrives, the message grows clearer. Slowing down may give kids the best chance to thrive online and off.

Nothing cancels this year’s CMF phone due to RAM prices

Nothing cancels this year’s CMF phone due to RAM prices

Nothing’s next budget phone is the latest victim of RAMageddon. As 9to5Google reports, Nothing co-founder Akis Evangelidis announced in a post on X that a follow-up to the CMF Phone 2 Pro won’t be coming this year:

We were working on a successor but with memory prices where they are right now, we can’t build a phone that feels like a genuine step forward at a price that makes sense for CMF. As a result, we’ve decided not to launch a new CMF phone this year.

Last week, Nothing CEO and co-founder Carl Pei also said the RAM shortage has impacted the cost of the company’s mid-range phone, stating, “For Phone 4A, memory costs doubled between when we decided to build the device and when it launched. They’ve doubled again since.” According to Pei, “memory is now the most expensive component in a smartphone.” Nothing is far from the only company facing RAM pricing challenges — earlier this week, Tim Cook announced Apple will be raising prices, saying “the situation has become unsustainable.”

While there won’t be a new CMF phone this year, Evangelidis added in his post that CMF still has “several new products launching as well as some entirely new categories.” He also hinted that “the smartphone launch season at Nothing isn’t over yet.”

China’s brain chip breakthrough raises big questions

China’s brain chip breakthrough raises big questions

NEWYou can now listen to Fox News articles!

A coin-sized brain chip in China could help people with paralysis control devices using their thoughts. China has approved a brain-computer interface called NEO for commercial medical use in certain patients with paralysis caused by spinal cord injuries. That moves brain-chip technology out of research trials and closer to real-world medical care.

Developed by researchers at Tsinghua University and Shanghai-based Neuracle Technology, NEO sits under the skull but rests on the brain’s protective outer layer rather than piercing deep into brain tissue. That design could make it less invasive than some competing implants.

For patients who have lost movement, this kind of technology could be life-changing. It could help restore a level of independence that once felt out of reach. But here’s where we need to slow down a bit. If a brain chip can turn your brain signals into digital commands, we need to ask who controls that data and how well it is protected.

BRAIN IMPLANT ENABLES ALS PATIENT TO COMMUNICATE USING AI

What is China’s NEO brain chip?

NEO is a brain-computer interface, often called a BCI. These systems read brain activity and translate it into commands for an external device. In this case, the implant uses sensors placed near the brain’s motor-control area. Those signals can help a patient operate equipment such as a robotic glove or computer interface.

What makes NEO especially notable is its placement. Brain-computer interfaces can be designed in different ways, and some go deeper into the brain than others. The company most people know in this space is Neuralink, the brain-chip startup co-founded by Elon Musk. Its implant uses tiny threads that enter the brain’s cortex. NEO takes a less invasive approach by placing electrodes on the dura mater, which is the protective membrane around the brain.

That design matters because every brain implant carries medical risk. Surgery can cause bleeding, swelling, infection or tissue damage. Even a small complication in the wrong part of the brain can affect speech or movement.

China’s approval does not mean brain chips are suddenly available for anyone who wants one. This remains a medical device for a narrow group of patients. Right now, the focus centers on helping people with severe paralysis regain some digital or assisted movement control.

Why China’s brain chip breakthrough matters

The medical upside here is hard to deny. More than three billion people worldwide live with neurological conditions, according to the World Health Organization. That includes people dealing with stroke, epilepsy, Parkinson’s disease, spinal cord injuries and other serious conditions.

For someone who has spent years unable to move freely or communicate easily, even a small amount of restored control could feel enormous. That is why brain-computer interfaces are getting so much attention. They could give some patients a new way to interact with the world around them.

Neuralink has already shown what that can look like in real life. Audrey Crews, a Neuralink trial participant who has been paralyzed for years, publicly shared that she wrote her name using the implant by controlling her computer.

How China’s brain chip compares with Neuralink

Elon Musk’s Neuralink has attracted most of the public attention in the U.S. brain-chip race. Musk has talked openly about restoring movement, helping people communicate and one day addressing vision loss.

Neuralink received approval to begin human trials, and more than 20 people have reportedly received its implant through testing. However, it has not received broad FDA approval for general commercial use.

China’s NEO approval puts a different kind of pressure on the field. It shows that China wants to move brain-computer interface technology into its health system and build a major industry around it.

This also fits a larger pattern. China has made BCI development part of its strategic technology push. The country wants breakthroughs by 2027 and a globally competitive brain-computer interface industry by 2030.

Why brain chip privacy is such a big concern

We already worry about phones listening, apps tracking location and smart TVs collecting viewing habits. Brain-computer interfaces take that concern to another level.

A BCI collects signals from the nervous system. Today, that may mean decoding movement intent, such as whether a patient wants to move a cursor left or right. But as the technology improves, the data could become more sensitive.

That raises some big questions. Who owns the brain data? Can it be sold, shared or used to train AI systems? Could an insurer, employer or government ever demand access? What happens if a company changes its privacy policy after the implant becomes part of someone’s daily life?

Those questions sound dramatic until you remember how many connected devices began as conveniences and turned into data pipelines.

A brain chip designed for medical help should not become another ad platform, another surveillance tool or another database waiting to be breached.

YOUR HEALTH DATA IS BEING SOLD WITHOUT YOUR CONSENT

Could hackers target brain-computer interfaces?

This is where the whole brain-chip conversation gets very serious. Any device that connects to a computer raises security questions. A brain-computer interface raises even bigger ones because it deals with signals from your body and, in some cases, the devices that help you move or communicate.

The concern here is someone getting access to neural data, device settings or the commands moving between the implant and outside equipment. Think about that for a second. If a brain chip helps someone control a robotic hand, a wheelchair or a communication device, a security failure could affect far more than privacy. It could affect that person’s independence and safety. That to me is scary.

Companies building these devices need to treat cybersecurity like part of the surgery, not some software update they figure out later. Encryption, strict access controls, medical-grade testing and clear update policies should be baked in from day one.

And because a brain implant may stay inside a person’s body for years, long-term support has to be part of the deal. No one should end up with an outdated implant in their head because a company moved on to the next big product launch.

What China’s brain chip means to you

For now, this technology is geared toward patients with serious medical needs. So, no, most of us are not lining up for a brain chip anytime soon. But this should still get your attention.

We already give up a lot of personal data through our phones, watches, cars and smart home devices. A brain implant takes that to a whole different level because the data comes from inside the body. That is about as personal as it gets.

Before this technology moves beyond hospitals and medical trials, patients need plain answers before they agree to anything. They should know who can access the data, how long it gets stored, whether it can be shared and whether it can help train AI systems.

The medical potential here is incredible. Helping someone regain control or communicate again could change a life. But the privacy protections need to be just as strong as the technology itself.

Kurt’s key takeaways

China’s NEO brain chip could be a huge step forward for people living with paralysis. If this technology helps someone regain control or communicate again, that is powerful. But I also think we need to be very careful here. Once a device connects your brain signals to outside technology, the privacy stakes change fast. We are talking about data tied to your nervous system. That to me is the line we need to watch closely. Brain chips could do incredible good. But companies and governments need clear limits before this technology moves any further into everyday life. The promise is real. So are the risks. And when the data comes from inside your own head, “trust us” will never be enough.

NASA selects Eric Schmidt’s rocket company for a 2028 mission to Mars

Relativity Space, the rocket company led by former Google executive Eric Schmidt, was picked to launch NASA’s Aeolus payload to Mars in 2028, as reported earlier by TechCrunch. Under a new public-private partnership, Relativity Space will provide the “spacecraft, rocket, and cruise operations” to fly Aeolus to Mars, where the payload will “provide the first integrated, daily, global view of Martian winds, temperatures, dust, and clouds.”

The Aeolus payload will have four instruments on board for studying the Martian atmosphere, which NASA says will “directly inform entry, descent, and landing systems and support safer, more predictable mission planning for astronauts.”

Schmidt, who served as CEO of Google from 2001 to 2011, became Relativity Space’s CEO in 2025, a couple of years after it launched the “world’s first 3D-printed rocket,” Terran 1, which failed shortly after launch. Relativity Space’s larger Terran R rocket isn’t scheduled to have its first launch until later this year.
