See the stunning first images from the Vera C. Rubin Observatory

Today, that promise has become a staggeringly beautiful reality. Rubin’s view of the universe is unlike any that preceded it—an expansive vision of the night sky replete with detail, including hazy envelopes of matter coursing around galaxies and star-paved bridges arching between them. “These images are truly stunning,” says Pedro Bernardinelli, an astronomer at the University of Washington. During its brief perusal of the night sky, Rubin even managed to spy more than 2,000 never-before-seen

I Was Overwhelmed by Mattress Shopping. This $374 Mattress Topper Bought Me a Few More Comfortable Years

CNET's key takeaways The ErgoAlign Mattress Topper from Helix normally costs $499 but it's on sale right now for $374 for the queen and $328 for the full size. It's a comfortable, band-aid solution until my next big mattress purchase. But it's pricier than other mattress toppers. The Nest Bedding Cooling Topper is $100 less, for example. I'm reaching the eight-year mark with my current mattress -- it's time to shop for a new one. But when I look around at the available mattress options, I ge

Child Welfare Experts Horrified by Mattel's Plans to Add ChatGPT to Toys After Mental Health Concerns for Adult Users

Is Mattel endangering your kid's development by shoving AI into its toys? The multi-billion dollar toymaker, best known for its brands Barbie and Hot Wheels, announced that it had signed a deal to collaborate with ChatGPT-creator OpenAI last week. Now, some experts are raising fears about the risks of thrusting such an experimental technology — and one with a growing list of nefarious mental effects — into the hands of children. "Mattel should announce immediately that it will not incorporate

Best Mattress Toppers for 2025, Tested by Our Sleep Experts

CNET’s sleep experts have been testing mattresses and their toppers for years. We carefully evaluate firmness, feel, construction and wa

James Gunn Says ‘Get Off Matt’s Nuts,’ ‘The Batman’ Sequel Will Happen When It Happens

Cool your jets Batman fans, James Gunn has heard you loud and clear over the highly anticipated sequel to Matt Reeves’ The Batman. So much so that he recently expressed his frustration with the demand in defense of the time DC Studios was taking. “Listen, we’re supposed to get a script in June. I hope that happens. We feel really good about it,” Gunn told Entertainment Weekly, and colorfully added, “People should get off Matt’s nuts because it’s like, let the guy write the screenplay in the amo

King-Size Bed Dimensions: Everything You Need to Know Before Buying a Larger Bed

The more we start to understand about our sleep, the more we realize how vital it is to our physical and mental health. In some cases, it can even prematurely age our brains and shorten our lives. But getting a good night's sleep isn't easy if your bed isn't up to the job, and that's why choosing a big, comfy one is always a good idea. Don't just take our word for it, though. A recent CNET survey found that six in 10 US adults would consider investing money to get better sleep, with 46% leaning

Astronomers Suggest That Entire Stars Are Being Obscured by Giant "Lampshades" of Dark Matter

Hunting for dark matter, the invisible substance thought to account for 85 percent of all mass in the cosmos, isn't easy. If it interacts with light at all, it does so incredibly weakly. Still, we can see its handiwork everywhere, with its gravitational pull determining the formation of everything from whole galaxies to individual stars. Now a team of astronomers is proposing a new technique for searching for dark matter — and it runs counter to its reputation as a completely invisible, light-i

As ChatGPT Linked to Mental Health Breakdowns, Mattel Announces Plans to Incorporate It Into Children's Toys

Hey kids! Ready to evoke the rich tapestry of the human experience with your favorite toys by harnessing the power of artificial intelligence? Mattel, the maker of Barbie dolls and Hot Wheels cars, has inked a deal with OpenAI to use its AI tools to not only help design toys but power them, Bloomberg reports. Details are scant at this point. In a joint interview, Mattel chief franchise officer Josh Silverman and OpenAI chief operating officer Brad Lightcap said the collab is at an early stage,

Man Unable to Sleep When His AI-Controlled Mattress Suffers an Outage

YouTuber Theo "t3.gg" Browne had a bizarre — and hilariously 21st-century — reason for suffering through a sleepless night. "Woke up because my AI-controlled bed is too cold," the San Francisco-based content creator wrote in a tweet that has since gone viral. Browne owns an intelligent mattress cooling system called Pod3, created by sleep tech company Eight Sleep. It boasts a host of sensors that track biometrics, including heart rate and sleep stages. An optional cooling cover cycles cooled o

Astronomers Just Solved the Mystery of the Universe's Missing Matter

Decades ago, astronomers estimated that “ordinary” matter (basically everything that isn’t dark matter or dark energy) makes up 5% of the universe. There was just one problem—they had no idea where most of it was. Astronomers from the Center for Astrophysics Harvard & Smithsonian (CfA) and the California Institute of Technology (Caltech) have tracked down the universe’s “missing” matter. Fast radio bursts (FRBs) indicate that over three-quarters of ordinary matter, officially called baryonic ma

Toy-maker Mattel accused of planning “reckless” AI social experiment on kids

After Mattel and OpenAI announced a partnership that would result in an AI product marketed to kids, a consumer rights advocacy group is warning that the collaboration may endanger children. It remains unclear what shape Mattel's first-ever AI product will take. But on Tuesday, Public Citizen co-President Robert Weissman issued a statement urging more transparency so that parents can prepare for potential risks. Weissman is particularly concerned that ChatGPT-fueled toys could hurt kids in unkn

King-Size Bed Dimensions: How to Sleep Like a King in Your Own Bedroom

It is no secret how valuable sleep is to our wellbeing. Not getting enough sleep can affect our mental health, prematurely age our brains and even affect how long we live. Part of getting the right amount of sleep is having the right mattress. Before you can buy your next bed, you need to know the right mattress size for your room. A king bed gives a ton of space for sleep and makes room for sleeping partners, but it also demands a lot of space in your bedroom. If you're thinking about buying

Best Air Mattresses of 2025, Tested by CNET Experts

There are a few general things to consider when shopping for the best air mattress. Price Price is the primary criterion for most people searching for the best air mattress. A queen-size bed can cost as little as $30, while the most expensive air mattresses can cost hundreds of dollars. A higher price doesn't always mean a taller air bed, a better air mattress, better air pressure, a self-inflating mattress, a better sleeping surface, more comfort or a decent night's sleep. Inflation The bes

What Type of Mattress Is Right for You? (2025)

If you're looking to buy a mattress, I don't need to tell you the research process is complex.

Best Organic Mattresses (2025): Certified Nontoxic, Natural Sleep

Certified organic mattresses are made of natural, organic materials that have been independently tested to meet standards. Not all “organic”mattresses are equal though. We’ve narrowed our search by sticking with companies that have certifications like the Global Organic Latex Standard (GOLS) and ‌Global Organic Textile Standard (GOTS). GOLS covers latex, which has a pretty complex manufacturing process that is not always the healthiest, but GOLS ensures that the finished results is as free of ha

Nolah Evolution Hybrid Mattress Review: A Jack of All Trades

Kwikset’s newest smart lock gets almost everything right

Legacy lock maker Kwikset has been producing innovative smart locks since 2013, when it released the first touch-to-open lock, the Kwikset Kevo. The company followed that up with the launch of one of the first key-free locks in 2016, one of the earliest Apple HomeKit locks, and one of the first fingerprint-only locks.

Best Gel Mattress for 2025, Tested by CNET’s Bed Experts

We've been testing mattresses, bedding and sleep accessories for years -- a few members have been doing this for eight years already. We estimate that our team has rolled around and slept on 350 different mattresses from dozens of brands, ranging from bigwigs like Serta and Tempur-Pedic to niche players like Sonu and Airweave. Our bed testers have varying body weights and types, heights, genders and sleep preferences, which allows us to provide an overarching assessment of each mattress from a
