First moon samples in over 40 years may alter lunar history

«Our current views need readjustment» about how long our beloved white globe remained warm and volcanically active, says a researcher.

In late 2020, a Chinese space capsule delivered fresh moon samples to Earth for the first time in about four decades, and these precious lunar rocks just revealed a new detail about our planet’s glowing companion: Its volcanoes were alive and active considerably longer than scientists thought.

«All our experience tells us that the moon should be cold and dead 2 billion years ago. But it is not, and the question is, ‘Why?'» said Alexander Nemchin, a professor of Geology at Australia’s Curtin University and author of the analysis published Thursday in the journal Science.

Alongside an expansive and international team of researchers, Nemchin discovered that some of the newly transported moon rocks contain lunar fragments from later days of the white orb’s timeline. Dated about two eons ago, these fragments are relatively young. But here’s the kicker: Those same pieces are also remnants of a volcanic eruption.

Connecting the dots, the team members realized they were looking at solid confirmation that the lunar surface was alive pretty late in the game.

«We need to dig deeper with this,» Nemchin remarked. «We are highlighting that our current views need readjustment — further research will tell how dramatic this readjustment should be.»

Welcome back, lunar research

The saga began last year in December, when China’s Chang’e 5 mission sent a spacecraft to scrape the surface of the moon and collect a variety of rock and dust samples for Earth-based analysis. It returned with about 4 pounds (2 kilograms) of extraterrestrial material.

The year 1976 marks the last time lunar samples were brought down to our home planet, an achievement of the Soviet Union’s Luna 24 mission. But before that, NASA’s Apollo missions were running the course from Earth to the moon several times — the crusades returned photographs, moon rocks and personal anecdotes of astronauts.

«There was some need and drive to do this 50 years back,» Nemchin explained. «Then, priorities changed and everybody moved to something else.» But now, he says, «we have the moon back in the focus.»

He notes lunar research is important not only from an astronomy perspective, but also because any effort to travel to the moon — or really, any space exploration — tends to expedite technologies that ultimately benefit us on Earth.

One example of such serendipitous tech comes from Australian physicists’ research in the ’90s. They developed a highly complex mathematical tool hoping to detect smeared signals of black holes that vanished in the cosmos. Unfortunately, they never found any — but their invention paved the way for modern-day Wi-Fi.

Moon rock science

«Every new sample gives us a big boost in understanding what is happening, simply because we still have so few of them,» Nemchin remarked. «Apollo samples have been worked on for the last 50 years and are still actively investigated.»

While analyzing the rocks brought back by Chang’e 5, Nemchin and fellow researchers first checked out what types were present. In particular, they were after basalt fragments, which are correlated with volcanic activity.

«We needed to get an idea about chemical composition of the fragments to be able to compare [them] to the large basaltic field visible from the orbit,» he said. «And, make sure [those] fragments represent this field of basalts and do not come from somewhere else.»

Then, the scientists confirmed specific ages of the pieces of interest. Validating that these fragments are young was one of the main goals of the mission. That’s how the team members expected to prove their hypothesis of the moon having active volcanoes more recently than textbooks suggest.

«All basalts we had before are older than 3 billion years,» Nemchin said. «We also had a few very young points determined from material ejected by very young impacts — impact melts — but nothing in between. Now we have a point right in the middle of the gap.»

Such age determinations are called crater counting, something the team hopes to continue doing in the future in order to attain the full array of rocks to map out each generation of the moon. Nemchin also notes that a few interesting chemical features were found in the basalt samples, including high iron content, which isn’t present in any other retrieved pieces of the lunar surface.

Further chemical research on the rocks, he says, will help answer new questions introduced by the team’s novel findings, such as searching for the source of heat that led to lunar volcanic activity a couple of billion years ago.

And at the end of the day, the Australian geologist emphasizes that «what is important for me in all this is that we managed to bring a large international group of people to work on the sample.»

«Somehow,» he added, «In the current situation when international travel is still rather restricted, I had more interaction with different people than in the previous years when we could move around any way we liked.»

My Kid Wanted Video Games. I Was Against It. This Console Gave Us Both the Win

The movement-based Nex Playground might be the antidote to parental screen time guilt.

When our 8-year-old started asking for video games, I knew we were about to engage in an uphill battle. Anytime we’ve been to friends’ houses with gaming consoles, he goes full zombie mode, then has an epic meltdown once the sensory overload wears off. And since he inevitably ropes his 6-year-old brother in, we’re essentially sealing both their fates.

So when our neighbors started raving about a movement-based gaming console called Nex Playground, my first instinct was to shut it down. The words «gaming console» alone were enough to put me in a mental block. Add in my own memories of Wii tennis sessions where I nearly took out the ceiling fan, and I was firmly in the «no» camp.

But after doing a little more research, I was intrigued enough to try it out.

Screen time isn’t something I take lightly. With three kids ages 2 to 8, my husband and I have always been intentional about how and what they watch. They don’t have their own tablets, and most of their screen time happens on our family TV, which means whatever the oldest is exposed to quickly trickles down to our toddler. So anything we bring into the house has to work for all of them. Tall order, I know, but the Nex Playground gets surprisingly close.

Getting started is easy

The console itself is refreshingly simple. It’s a small cube, slightly larger than a Rubik’s cube, with a circular camera and motion sensor, a light indicator and two ports for power, and an HDMI connection to the TV. There’s no controller beyond a basic remote for navigating menus. For most games, your body is the controller.

Setup is quick. Plug it in, connect it to your TV, and you’re ready to go. It doesn’t store video or upload footage to the cloud, which was an immediate plus. It also comes with a magnetic privacy cover that you can put on the lens when it’s not in use.

At $250, it’s not cheap, but it’s less than some of the popular gaming consoles for this age range, like the Nintendo Switch 2. That gets you a five-game starter pack: Fruit Ninja, Go Keeper (soccer), Starri (think Guitar Hero for your whole body), Party Fowl (an AR emoji frenzy) and Whack-a-Mole. Additional games require a subscription: $89 a year or $49 for three months, which unlocks a library of 50-plus games and counting. New titles dropped even as I was writing this.

The library spans a surprisingly wide range. There are board game adaptations like Connect Four and Candy Land, character-driven games with Peppa Pig, Bluey and the Ninja Turtles, and sports like baseball and, yes, tennis — minus the ceiling fan hazard. There’s even parent-friendly content like Zumba workouts, which I may or may not have fully committed to on a rainy afternoon.

Even my toddler has gotten in on the action, mostly bouncing her way through Hungry Hungry Hippos when her brothers finally concede.

Gameplay is where it wins

The movements range from swinging your arms to keep a ball in motion, hopping or full-body launches that are far more aggressive than what the game actually requires. (I’m not about to tell the kids otherwise.) After a 45-minute session, my kids are tired and sometimes even drenched in sweat. The Nex Playground entertains and burns energy in one fell swoop.

The graphics also seem intentionally simple and arcade-like, which fits the minimalist play experience. There’s no POV storyline to get lost in, no leveling up into a new world at 9 p.m. on a school night. Some games keep score, which awakens my kids’ competitive streak, but the vibe is more collaborative and hasn’t been the catalyst for more fighting like other games. If anything, it’s done the opposite.

I still don’t love defaulting to a screen when my kids are bored, so we try to use it in moderation. In our house, piano practice is the only thing that unlocks weekend play time, and the fact that they’ll sit at the piano for a full hour tells you everything you need to know.

The verdict that matters most

But the real test: Does it hold up to an 8-year-old who was dead set on a Nintendo Switch?

Short answer: yes. At least for now. He’d still pick the Switch if you asked him, but not for the reasons you’d expect.

«The Playground is more tiring,» he told me, which only helped seal the deal for me. His current favorite is Homerun Hitters. «It’s basically a baseball game where you go against ranked global players. Me and my brother are really good at it.»

This from a kid whose primary hobby is annoying his younger brother. The fact that he said «me and my brother» as a collective was an unexpected bonus.

The Switch may still show up on the Christmas list this year. And realistically, I know I’m on borrowed time. As kids get older, «cool» becomes the currency, and a motion-based cube probably won’t hold up against an Xbox or a Switch once playdates turn into side-by-side gaming sessions.

The Nex Playground isn’t a replacement for those. It’s more of a detour; it gives them a taste of gaming without all the usual side effects. Even if I do eventually cave, I can still see it sticking around for the occasional family game night or as a rainy-day sibling diffuser.

In the meantime, I’ll relish this simpler version of gaming while I still can. He’s not exactly rushing me to return this review unit. More importantly, neither am I.

Don’t Wait for New Emoji in iOS 26.4, Here’s How to Create Them on Your Own

If your iPhone has Apple Intelligence, you can create your own emoji now.

Apple will likely add new emoji to your iPhone when the company releases iOS 26.4. Those new emoji could include an orca, a distorted smiley face and more. According to Emojipedia, there are 3,953 emoji with more on the way. The current list of emoji include smileys, sports players, weather conditions and flags. But there’s no emoji for a dog wearing pajamas, a plate with burgers and fries and many other things. But if you have Genmoji on your iPhone you can create these emoji and many more.

Apple released iOS 18.2 in 2024 and the company introduced its own emoji generator, called Genmoji, to Apple Intelligence-capable iPhones at that time. The Unicode Standard, a universal character encoding standard, is responsible for creating new emoji, and approved emoji are added to all devices once a year. With Genmoji, you don’t have to wait for new emoji to appear on your iPhone each year. You can just create them as you need them.

Read on to learn how to use Genmoji on iPhone to create your own custom emoji. Just note that only iPhones with Apple Intelligence, like the iPhone 17 lineup, can use Genmoji at this time.

How to make custom emoji

1. Open Messages and go into a chat.
2. Tap the plus (+) button next to your text box.
3. Tap Genmoji.

You can then type a description of an emoji into the text box near the bottom of your screen and tap the check mark on your keyboard to enter that description into Genmoji. You can also tap different suggestions and themes that are right above the text box. And with iOS 26 or later, you can also combine and use emoji to create others rather than describing a new emoji or using suggestions.

Your iPhone will generate a series of new emoji for you to pick from according to your description, and you can swipe through these new emoji. When you find the one you want, tap Add in the top right corner of your screen and the new emoji will be available to use as an emoji, tapback or a sticker. Now you don’t have to wait for the Unicode Standard to propose, create and bring new emoji to devices.
