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.»

We Learned How to Share Info About ICE and Police Raids on Apps Like Ring Neighbors
If you’re wondering how to post about ICE on neighborhood apps, here are some tips.
The US Immigration and Customs Enforcement agency has been in the spotlight due to its repression of immigrants and targeting of protesters, not only in Minnesota but across the country. The FBI has also been investigating related Signal chats, and Facebook is taking down posts about ICE. Earlier this month, the Foundation for Individual Rights and Expression accused the Department of Homeland Security of forcing tech companies to censor «protected speech» on social media platforms.
I contacted two social platforms — Nextdoor and Ring Neighbors — to see what they allow and what happens when you see ICE activity from your video doorbell or in person. I learned what sort of posts they allow, what gets taken down and how to talk about nearby raids. Here’s what you should know, too.
Are posts getting banned on apps like Ring Neighbors?
I reached out to Ring about its Neighbors app policies regarding recent events and police raids, as well as Reddit reports about posts being taken down. The company provided information about its policies and explained why Ring tends to remove certain posts or prevent them from going live on Neighbors.
Posts about a general law enforcement presence can get nixed. So if someone said ICE was spotted in «Bell Gardens,» their post would be denied because that’s too vague. Or if a post asked, «Hey, is there any ICE activity in town?» it wouldn’t be allowed. Other posts get banned if they:
- Explicitly obstruct law enforcement
- Voice political opinions
- Assume immigration status or other types of prejudice
- Don’t pertain to local events

What’s a safe way to post about police activity?
Posts that cite an exact location or images showing agents directly connected to an event tend not to be taken down. If someone said, «I saw ICE knocking on doors at the IHOP on Florence and Pico,» that would be allowed under Ring’s guidelines. Other allowed posts provide information on the exact cross streets, addresses, complexes, blocks and so on.
Bans aren’t always immediate. Sometimes posts that violate guidelines are taken down after the fact, either through post-published moderation, flagging or user deletion. Customers can usually appeal moderation decisions to ensure consistency.
When I turned to Nextdoor, another popular neighborhood app used for discussing events, a company spokesperson said something similar: «Our platform fosters discussions of local issues and, as such, our Community Guidelines prohibit broad commentary or personal opinions on national political topics.»
As long as it’s a local issue and users follow the basic community guidelines (be respectful, don’t discriminate and use your true identity), then posts should be fine.
What are the guidelines for posting on Ring Neighbors?
When I visit my own Neighbors app, I see — contrary to some reports — that users frequently post about hearing sirens or police activity in their own neighborhoods, ask about masked strangers or raise questions about law enforcement.
You can still post about security concerns on Ring Neighbors and other apps, even and especially when they involve police activity. You can also post about people you don’t recognize and strangers knocking, which opens the door (not literally) to talking about masked federal ICE agents who aren’t wearing any identifiers.
In other words, it looks like what Ring said mostly tracks. Explicit information citing current, local events, preferably with address data, is allowed.
«Focus on the behavior that raised your suspicion,» Nextdoor recommends. «Describe the potentially criminal or dangerous activity you observed or experienced — what the person was doing, what they said (if they spoke to you). Include the direction they were last headed.» If you post with an eye toward your neighborhood’s safety, your post is less likely to be removed.
Finally, avoid posts that include gruesome content or violate someone’s privacy, as these are also red flags likely to lead to a block.
Is Ring currently sharing information with ICE?
You may also be concerned that Ring is sharing your security videos with ICE or the surveillance company Flock Safety. In early 2026, Ring canceled its pending contract with Flock and has not announced any direct arrangements with law enforcement services.
Ring’s published guidelines say the company doesn’t share information with the police or federal agencies without a binding request, such as a search warrant, subpoena or court order. However, since Ring’s plans have changed abruptly over the past several months, they could shift again in the future. CNET will continue to report on further developments.
Can users coordinate on apps like Ring Neighbors?
This is a gray area, and it’s hard to know whether discussions will be removed. In my experience on the Neighbors app, many discussions about sirens and unexplained police presence were left up, allowing people to share their own perspectives and what they heard on police scanners.
It’s possible that the more these posts mention ICE or federal enforcement, the more likely they’ll be removed, and if conversations move into discussions about national issues or general legal advice, they may be taken down. But many people have reported successfully using apps like Neighbors to discuss nearby law enforcement raids, so I don’t see any evidence of a blanket ban.
Groups using the Neighbors app to communicate important information or provide help should also be aware of the Neighbors Verified tag, which is available to public safety agencies and community organizations. This tag makes it easier for Neighbors users to trust information and announcements from specific accounts. Verified accounts don’t have access to any additional user information.
Can agents cover up my security cam or doorbell?
In the past, published footage and news reports have shown federal agents covering up a video doorbell during an ICE raid. While it’s not common, civil rights attorneys have said actions like these are illegal. This issue connects to a larger fight over filming ICE in general, something the Department of Homeland Security has said is illegal, and US courts have said is protected under the First Amendment.
Devices on your own property should be fine if ICE follows the current law — you can find more details here — but it’s always a good idea to immediately save any pertinent video footage, preferably in more than one device.
What are my rights if I’m worried about ICE raids?
Whether you’re concerned about federal immigration raids, curious about what law enforcement is doing or just want clarification about your rights, it’s a good idea to consult the American Civil Liberties Union and the National Immigrant Justice Center. Here is some advice they give.
- Don’t escalate: In cases where federal agents or people appearing to be agents have knocked on doors, people have done nothing and simply waited for agents to leave. Remember, without a warrant, they usually can’t enter a house, and if you have a video doorbell, it can still record everything that happens. Avoid confrontation when possible, and don’t give law enforcement anything to act on. Remember, everyone still has the right to remain silent.
- If you feel your safety is endangered, call 911 or seek help from a nonprofit: Calling 911 is very helpful if you feel unsafe because of nearby events. You can explain the situation and have a record of the call. 911 is an emergency response service and isn’t in the business of reporting to federal agents. There are also local immigrant rights agencies you can contact to report ICE, and groups like the ACLU can usually point you in the right direction.

This 160-Watt Anker Charger Just Dropped to $106, but Probably Not for Long
The Anker Prime charger can power three devices simultaneously, including laptops.
You’ll never run out of charging ports again with this Anker 160-watt, three-port charger, especially while it’s down to just $106. It’s currently at its lowest price of the year, but we can’t promise that it’ll stay that way. That’s why we recommend acting fast if you want to snag this bargain charger.
This Anker charger would normally set you back around $150, so you’ll save $44 with this deal. You won’t even have to enter any discount codes or clip any coupons to do it.
The charger has three ports pumping out a total of 160 watts of power — and a single port can charge at 140 watts. That’s enough for the M5 14-inch MacBook Pro and even its larger 16-inch relative, too.
There’s a handy display that shows you information on how the charger is performing, and the pins can be folded away to make the charger perfect for traveling. In fact, Anker’s charger is around the same size as a pair of AirPods Pro 3 earbuds, so it’s highly portable.
Why this deal matters
You can never have too many chargers, and this one does the job of three. It isn’t cheap, to be sure, but with plenty of power on tap and a design that makes it great for taking on the road, it’s still a great buy with this discount.

Meta and AMD’s Multibillion-Dollar Deal Is All About the AI Chips
Meta will take a stake in the chipmaker in exchange for a commitment to buy billions of dollars’ worth of AI chips.
Meta is joining OpenAI as one of the major tech companies to take a stake in chipmaker AMD, as part of an AI hardware buying frenzy. Meta and AMD on Tuesday announced a partnership that will involve CEO Mark Zuckerberg’s tech giant buying billions of dollars’ worth of AMD Instinct GPUs in order to fuel its ambitions to build out AI offerings across Meta platforms, including Instagram, Facebook and WhatsApp.
In a release, Meta described the deal as «multi-year,» and said the AI purchase will provide Meta with up to 6 gigawatts of AMD GPUs, «the silicon computing technology used to support modern AI models.»
According to the US Department of Energy, a single gigawatt (1 billion watts) is equivalent to nearly 2,000 large solar panels or 100 million LED bulbs.
In AMD’s version of the announcement, CEO Lisa Su said, «We are proud to expand our strategic partnership with Meta as they push the boundaries of AI at unprecedented scale.» As part of the deal, Meta will take a 10% stake in AMD.
AMD, based in Santa Clara, California, previously signed a deal with ChatGPT-maker OpenAI that it announced last October, which is similar to the Meta deal and also gives its AI rival 10% ownership of AMD.
(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.)
What does this mean for the rest of us?
AMD’s two megadeals may not have an immediate impact on people who use Meta’s social networking and communications apps, or even on those who buy AMD’s products, including desktop processors and graphics cards.
But it signals that large companies making huge bets on the future of AI are doing what they can to secure the hardware they need as supplies tighten and prices rise for components such as RAM. Some of those constraints aren’t expected to end anytime soon, and shoppers could begin to see prices rise even more than they already have for computers, smartphones, vehicles and other products that heavily rely on computing components like these.
It is also a sign that Meta’s ambitions for AI are not slowing down as it continues to compete with companies including OpenAI, Microsoft and Google to develop AI products and tools.
Also a factor: Meta’s push into wearables
Another reason AMD may want access to AI chips goes beyond its own data centers and online platforms: Meta has increasingly been focused on wearables such as its Oakley Meta AI Glasses and other potential new portable products.
In addition to what AMD’s GPUs can offer Meta for AI infrastructure power, AMD may also be part of its wearable future.
«With AI models requiring unprecedented processing power to process real-time data and information, Meta is focused on securing the supply chain necessary for its wearable devices,» said Michael J. Wolf, founder and CEO of the consulting firm Activate.
Wolf believes that the deals Meta and OpenAI have signed won’t be the last time a major AI-focused company locks down a supply of semiconductors.
«As consumer hardware transitions from smartphones to smart glasses, we will absolutely see more of these mega-deals,» Wolf said.
