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.»

Social Media and AI Want Your Attention at All Times. This New Documentary Says That’s Bad

Your Attention Please, a documentary premiering this week at SXSW in Austin, Texas, explores how we live in the attention economy.

«Do you remember the world before cellphones?»

The question comes early in Your Attention Please, a documentary premiering this week at South by Southwest in Austin, Texas. And it hit me harder than I expected. As a 27-year-old tech reporter, I realized I don’t have too many clear memories of life before smartphones. My adolescence unfolded alongside the rise of smartphones, social media, push notifications and the routine of endless scrolling. Like many people my age, I’ve spent most of my life inside the attention economy — without ever really stepping outside it.

That’s the uneasy territory the documentary explores.

CNET was given exclusive early access to the film’s trailer, embedded below.

Exploring how tech shapes our behavior

Director Sara Robin said she originally set out to make something smaller: a documentary about people trying to reclaim their attention by breaking unhealthy phone habits. In an interview with CNET, Robin described the idea as a personal story about focus and self-control in an age of constant distraction.

As Robin interviewed researchers, technologists and families affected by social media and cyberbullying, the film’s scope widened. What started as a question about individual habits quickly became a larger investigation into how modern technology systems are designed to shape human behavior. The story stretches from the rise of social media to the emerging influence of AI.

Along the way, Robin and her collaborators kept hearing the same observation from different corners of the digital world: Social media didn’t just change how people communicate; it quietly rewired what we value. Experiences that were once private or emotional — friendship, affection, belonging — began to acquire numerical equivalents. Followers, likes, comments, views and shares began to be how we saw our own self-worth. In the architecture of social platforms, those numbers function as a kind of social currency.

Trisha Prabhu, a digital-safety advocate and inventor of the anti-cyberbullying technology ReThink, argues that social platforms did more than create new online spaces. She says they fundamentally reshaped how social validation works. The metrics that define popularity often reward attention-seeking behavior and amplify conflict, while genuine connection is now harder to quantify and, therefore, easier to overlook.

Prabhu warns that the same dynamics already driving problems like cyberbullying could accelerate as automated systems become more capable. AI tools can generate abusive messages at scale, produce convincing impersonations or create deepfakes that spread rapidly online. In some cases, the technology may even blur the line between human interaction and machine-generated communication, which could deepen loneliness or encourage harmful behavior.

«There’s AI exacerbating existing harms [like automating cyberbullying], but then I also think that there’s AI creating completely new harms,» Prabhu told CNET. «There are reports of AI tools encouraging users, including minor users, to commit self-harm… Even for the everyday user who’s not experiencing the extreme outcome, I think we have to ask ourselves how much of our time and connection we want spent with an AI tool as opposed to a fellow human being.»

Bringing attention to attention

What struck Robin during filming the documentary was how universal these anxieties felt. Across conversations with families, educators and advocates around the world, the themes were remarkably consistent: overstimulated attention, declining focus in classrooms, rising anxiety among young people and a persistent sense of dread that comes from always being plugged in.

Those shared concerns have helped spark a coordinated moment around the film’s release.

On March 11, more than 25 organizations focused on digital well-being will simultaneously release the trailer for Your Attention Please as part of an initiative called Stand for Their Attention. What began as a small collaboration among five groups quickly grew as word spread through advocacy networks. The coalition now includes organizations such as Common Sense Media, Protect Young Eyes, Mothers Against Media Addiction, the Center for Humane Technology, Smartphone Free Childhood and Scrolling to Death.

The idea behind the synchronized launch is simple: Use the attention surrounding the documentary to highlight the growing movement that’s already working to reshape digital culture.

Many people feel overwhelmed by the scale of the problem, Robin says, but behind the scenes, a widening ecosystem of advocates is experimenting with ways to build healthier digital environments, from redesigning products to changing norms around screen use.

The campaign also arrives at a moment of growing scrutiny around the attention economy. Lawmakers in the US and abroad are increasingly debating how social platforms affect youth mental health and childhood development. Boycotts around AI use are taking off. Researchers are studying how these algorithms and chatbots influence behavior. Individuals are trying to figure out how much technology belongs in everyday life.

What can we do about it?

Despite the weight of those conversations, Robin says the goal of the film isn’t to leave audiences feeling powerless. In fact, the rapid rise of public awareness around AI has made her more optimistic than she was during the early days of social media. The systems shaping digital life, she argues, are built by people, which means they can also be rebuilt.

«We have more power than we think,» Robin said. «And there are a lot of different ways to get involved in this, from changing individual habits to changing the culture in your own family and in your community, designing technology differently, getting engaged in these conversations, all the way to pushing for legislative change.»

The film intentionally avoids presenting a single solution.

Instead, Your Attention Please asks a broader question: What happens when attention, one of the most human parts of our lives, becomes one of the most valuable commodities in the global economy? And perhaps more importantly, what kind of digital world do we want to build next?
