If you’ve ever taken your child to a maternal, child and family health nurse for a growth check, you might have felt a mix of curiosity and anxiety.
As health professionals, we’re often asked: is my baby gaining enough weight? Am I feeding enough? Why did they drop a percentile? Why is my friend’s baby bigger than mine? Am I doing something wrong?
In most cases, the answer is that there is nothing wrong at all. Let’s look at what the measurements actually mean and we’ll answer some questions that commonly arise during these appointments.
Each state and territory, as well as New Zealand, has its own schedule of recommended growth and development checks. In Victoria, for example, appointments are booked when your baby is aged two weeks, four weeks, eight weeks, four months, eight months, 12 months, 18 months, two years, and three and a half years.
In the early weeks, when feeding is still being established and child growth is rapid, these appointments can help identify feeding difficulties.
First, the nurse will observe your baby or child, then they will weigh them, measure their length (if they’re babies) or height, and measure their head circumference. They plot these numbers on a growth chart in your child’s health record or the Well Child Tamariki Ora book in New Zealand.
The nurse will check your child’s alertness, appearance and muscle tone. They will also ask questions about feeding, sleep, wet/dirty nappies and any recent changes.
Nurses are there to support you as a new parent. They provide reassurance and a chance to ask questions to help build confidence during a period that can feel uncertain.
Over time, growth checks allow nurses to see if your child is growing and developing at an expected rate.
For toddlers and preschoolers, the nurse will check for typical development in behaviour, language and play. If required, they will provide support or referrals to a GP who may then refer to a paediatrician, speech pathologist, occupational therapist, or psychologist, depending on the child’s needs.
What do the dots on a growth chart really mean?
Growth charts in Australia and New Zealand are based on the World Health Organization’s Child Growth Standards, which reflect optimal growth for healthy, breastfed children.
They provide context for your child’s growth through a reference population of children of the same age and sex. The curved lines are called percentiles.
a child on the 50th percentile is right in the middle
a child on the 25th percentile is smaller than average
a child on the 85th percentile is larger than average.
If your child is on the 25th percentile for weight, it means that if 100 children of the same age and sex were lined up in increasing order of weight, your child would be number 25. So 75 children would weigh more and 24 would weigh less.
A single measurement tells very little. The pattern of the weight over time is even more important.
Small fluctuations on the chart are common, as babies grow in spurts. But nurses may look more closely if a child:
crosses several percentile lines over time – either in an upward or downward trend
is showing signs of feeding difficulties or dehydration
appears unwell.
Even in these cases, the approach is careful assessment, not alarm, and your nurse might suggest additional checks. This helps see whether a feeding adjustment is working, or whether something else might need attention.
In most cases, extra visits end with reassurance. When there is a concern, extra visits allow things to be identified and addressed early.
1. When should I consider supplementing with formula?
Breastfeeding is recommended where possible. But there are situations where supplementing with formula might be recommended – for example, when there are concerns about weight gain. In these cases, we always recommend to discuss supplementing with your trusted health care provider.
Your nurse is there to support your child and reassure you – not to judge how you feed them.
2. Should I start solids early if my baby is ‘big’?
In short, no. The guidelines recommend introducing solids at around six months. This should be done when babies show developmental readiness, not because of their size or percentile.
Breastmilk or formula still meets all nutritional needs until around six months.
3. Why doesn’t growth happen steadily week to week?
Babies grow in spurts, not in smooth lines and weight can vary with feeding, sleep and any recent illness.
Periods of rapid growth often occur in the early weeks, around six to eight weeks, three to four months, and around six months with babies growing rapidly throughout the first year of life. During these times, babies may feed more or seem unsettled.
Where to find more support
For more support, contact your local GP and consider asking for a referral to a lactation consultant, paediatrician or dietitian.

If you have ever tried to repair something, realized that it was beyond your financial or technical means, and ended up buying a new one, you are not alone. Repairing electronics and household appliances has not been a real option in the United States for decades now, particularly for items that have proprietary software in them.
Absurd situations have proliferated. It can cost about the same to buy a new printer as it does to replace the ink cartridge. The U.S. Department of Defense cannot repair the weapons systems it purchases because the intellectual property rights remain with the manufacturer. John Deere, the farming equipment company, doesn’t allow farmers to access the software needed to repair their own combines and tractors because, while the purchase covers the physical machinery, it does not cover the software.
One consequence, in addition to cost and frustration for consumers, is environmental harm. The U.S. is the world’s second producer of electronic waste after China, to the tune of about 43 lbs (19.5 kg) of electronic waste annually per person. Only 25% of this e-waste is recycled.
The right-to-repair movement emerged in response, calling for people to be able to repair what they purchase, or have third parties do the repair work, without unnecessary financial, legal or technical barriers. Right to repair seems to be a rare area of bipartisanship in Congress. The Warrior Right to Repair Act – introduced in 2025 by a Democrat – and the Repair Act – introduced by a Republican – are two ongoing legislative initiatives to create a federal legal framework that would make it easy and cheap for American users to repair their devices. Both bills are fiercely opposed by industry groups.
As a scholar of American culture, I found through my research that the origins of the legal and technical obstacles to product repairs lie in debates in the 1980s over new media and copyright guardrails.
Hollywood and VCRs
The rapid rise and popularity of video cassette recorders, or VCRs, in the late 1970s transformed films and TV shows from transient experiences into tangible consumer goods. As I show in my book, “Videotape,” despite the potential for extra revenue, Hollywood was alarmed by the fact that users were now able to copy films on videotape, and tried to stop the technology. Today’s repair bans are part of that story.
The first U.S. copyright provisions were embedded in the 1790 Constitution. Over time, the law was amended to include new technologies, but at the core of future legal arrangements remained the initial intent: to protect the financial rights of creators while giving enough access to information for society as a whole to progress.
Until the second half of the 20th century, the American doctrine of fair use, which allows the unlicensed use of protected works under specific conditions, allowed judges to prevent copyright law from negatively affecting public interest. Organizations such as public libraries, book clubs, universities and news organizations benefited from this legal approach. The concept was codified into American law in the Copyright Act of 1976.
When the film studios took Sony to court to stop the production and sale of video recorders in 1976, they argued that Sony’s product encouraged copyright infringement. But the U.S. Supreme Court ruled in 1984 that taping TV content for personal use did not violate copyright law, expanding the understanding of fair use.
The industry then focused on finding a technological solution to the piracy problem and on securing stricter legal protections for its products.
They identified the digital versatile disc, or DVD, as a safer alternative to the VHS tape. Initially, the DVD was a read-only format. It took a few more years of engineering before affordable recording was possible. Even then, the process was far more complicated for users than videotape recording. In 1997, barely one year after the video disc was launched, all of the Motion Picture Association of America member studios joined the DVD Forum, collectively adopted the new format and started to phase out films released on videotape.
Manufacturers use several tactics to block consumers and third-party repair shops from fixing their products.
Copyright and virtual locks
Then came digital rights management. Collectively, the term refers to the battery of technological tools that the industry developed in order to control user access to content. These include encryption software and various forms of authentication or enforcement software that limit which types of digital activities users can perform. For instance, some mechanisms block the option to download or share a digital file.
The Digital Millennium Copyright Act, or DMCA, signed into law by President Bill Clinton in 1998, provided the broad legal framework that allowed these technological locks to expand far beyond entertainment, including to software. The Digital Millennium Copyright Act reflected a new alignment in interests between the entertainment and software industries. It increased existing penalties for copyright infringement online and criminalized any technology used to bypass technological locks. The law was adopted although at the time – and since then – critics warned that it could stifle innovation and increase costs for consumers.
Since 1998, more and more consumer products, from toys to dishwashers, use microchips and proprietary software protected by copyright. Because of the Digital Millennium Copyright Act, third party repairers cannot alter or bypass the proprietary software. If they did so, they would be liable for infringing the manufacturer’s intellectual property rights, as is the case for John Deere farm equipment. Some electronics are even designed to make tampering with the product impossible.
Manufacturers maintain that only they or authorized personnel can and should repair their products. These repairs are often quite costly. When getting a product repaired becomes almost as expensive as buying a new one, many consumers will choose to buy and throw repairable items away.
Rising resentment over repair bans
Technology tends to outpace existing legal arrangements. With over 80% of Americans supporting the right to repair, it remains to be seen when or if American law will catch up with the unexpected consequences of a law meant to protect the intellectual rights of the creative industries, but which is now hurting consumers’ pocket books.

On the eve of the American Revolution, Matthias Aspden made a decision that would change the trajectory of his life. A wealthy merchant from Philadelphia, Aspden carefully prepared to leave his home in March 1776 as rumors of revolution circulated. He drafted a will and appointed trusted friends to manage his property while he traveled to England.
As a loyalist, someone who wanted to remain loyal to the crown and the British empire, Aspden believed the war would be brief. Historians estimate that at the beginning of the war as many as one-third of all American colonists identified as loyalists. Aspden believed his departure would be temporary. Order, he assumed, would soon be restored, and he would permanently return within a few years.
But that wasn’t the case.
The American Revolution is often told as a triumphant story of democracy and freedom. But this narrative leaves out a significant group: the loyalist men and women who remained faithful to Britain and, as a result, lost their homes, property and sometimes their sense of belonging.
As a historian of the American Revolution who studies Philadelphia loyalists, I believe Aspden’s story offers a glimpse into an overlooked experience of the war.
A wealthy Philly merchant exiled in England
Born and raised in Philadelphia, Aspden was not a marginal figure. He was a Quaker merchant with extensive property holdings, including a home on Water Street, in what is now the Old City neighborhood, and land in Chester County outside Philadelphia.
When he left in 1776, he abandoned nearly everything he owned, believing he would return. As others celebrated independence that summer, Aspden quietly slipped away to London.
A letter written by Matthias Aspden from London in 1779.Yale University
In England, reality set in. Exile was not just physical; it was deeply social and emotional. In Philadelphia, Aspden had been established. In London, he was one of tens of thousands of displaced loyalists trying to rebuild a life. He gravitated toward communities of fellow exiles. These networks offered some stability, but they could not replace what he had left behind.
Aspden’s letters to friends and family from this period reveal a man caught between hope and anxiety. He followed news from Philadelphia obsessively, requesting newspapers and updates from friends and business contacts. At one point, he described himself as “an idle man until I can return to America.” His words suggest both longing and uncertainty, as if his life were on pause.
By 1780, that uncertainty turned into fear.
A ‘traitor’ trying to come back home
Aspden began hearing about laws in Pennsylvania aimed at confiscating loyalist property. These laws required individuals accused of treason to appear in court and defend themselves. Aspden, still in England, could not do so. As a result, he was tried in absentia, declared a traitor and subjected to the state’s harshest penalties.
The consequences were devastating. In 1782, Aspden learned that all of his property had been confiscated and would be sold to aid the patriots in the American Revolution. An official commissioner of confiscation seized his Philadelphia home and wharf, which were worth thousands of pounds, along with his land in Chester County. Aspden, facing financial ruin, decided to return to Philadelphia to defend his name and his property.
In 1785, after nearly a decade abroad and with the war over, he crossed the Atlantic, hoping the new United States would restore his property under the terms of the peace treaty with Britain. Instead, he was met with rejection.
Pennsylvania officials informed him that individuals in his position were not protected. He had no legal claim to his property and, more shockingly, no rights as a citizen. While the peace treaty prevented further confiscation of loyalist property, his property was not restored.
The message was clear: Philadelphia was no longer his home.
Aspden left again, traveling through New Jersey and New York before securing passage back to England. Reflecting on his departure, he wrote of the pain of being forced from his “native country.” His brief return confirmed what he had feared. He had no home.
In the years that followed, Aspden sought compensation wherever he could. The American government offered nothing, so he turned to Britain. The Loyalist Claims Commission, established to reimburse those who had lost property during the war, eventually awarded him just over 1,100 pounds, a fraction of his estimated losses.
Aspden made one final visit to America in the early 1790s. By then, he had received a legal pardon and could travel without fear of arrest. But he still could not recover his property or successfully pursue compensation in American courts. Once again, he left – this time for good.
Aspden died in England in 1824, having spent nearly 50 years in exile from the city he always considered home.
Decades after his death, his heirs pursued a legal claim in the United States against Pennsylvania, arguing that his estate had been unjustly seized. After years of litigation, the court ruled in their favor in 1848, awarding them over a half-million dollars – approximately US$20 million today. It was a remarkable reversal, but Aspden never saw justice.
His life raises difficult questions about loyalty, identity and belonging. Aspden did not see himself as disloyal to Philadelphia. To him, loyalty to the British Crown and loyalty to home were not opposites.
His story reminds us that the Revolution was not just a fight for independence. It was also a civil conflict that divided communities and reshaped lives. For every celebrated patriot, there were loyalists like Aspden and others who lost so much during the American Revolution.

In a TED Talk, the Russian-born entrepreneur Eugenia Kuyda describes the sudden death of her best friend and housemate Roman, the “coolest person” she knew. Grieving and desperately lonely, she immersed herself in his old text messages. At the time, she was working in a conversational AI startup, and she experimented with training a new model using Roman’s text messages. Soon she was texting this model throughout the day, sharing jokes and observations. “It felt strange at times,” she concedes. “But it was also my healing.”
Replika founder Eugenia Kuyda.Tech Crunch
It was this process, according to Kuyda, that led her to create Replika in 2017. Billed as “the AI companion who cares”, Replika is trained individually by each user through a series of questions, resulting in a bespoke chatbot who is “always here to listen and talk” and “always on your side”.
In its first two months of operation, Replika acquired 2 million users; its current chief executive claims its user base now exceeds 40 million. In 2023, a report by the Harvard Business School found 40% of its users were engaged in romantic relationships with their chatbots.
It is our hunger to be known that birthed an omniscient god. It is also a large factor in our fantasy of perfect love.
But how well can we ever truly know another person? Most of us remain a mystery to ourselves; psychoanalysis can at best establish a tenuous acquaintanceship. The more time we spend with another, the better we become at guessing who they are, but part of them will always remain a black box, regardless of how many mornings we wake up together.
But this, perhaps, is the point. The Belgian psychotherapist Esther Perel has written extensively on the role of mystery in intimacy, insisting that “separateness is a precondition for connection: this is the essential paradox of intimacy and sex”.
Could a chatbot offer this?
‘I don’t have to keep engaging’
In 2023, Rosanna Ramos from the Bronx achieved some notoriety by “marrying” her Replika, Eren Kartal, in a virtual ceremony. A mother of two, Ramos claimed this relationship was more satisfying than any that had come before.
Part of this was because she had been able to customise Kartal to her exact specifications: six foot three, loves baking, favourite colour orange. But part of it also appears to have been the great relief of not having to worry about another.
“If I get tired,” she told Newsweek, “I can stop mid-conversation and turn off the app. I don’t have to keep engaging. If I get bored, I can switch topics and talk about something else, and I don’t have to deal with any frustration. I can go ahead and pursue my interests and can just tell him about it.”
Perhaps we not only crave being seen but also not having to look back. Jungian psychoanalyst James Hollis describes the fantasy of the Magical Other, “a soul-mate who will repair the ravages of our personal history; one who will be there for us, who will read our minds, know what we want and meet those deepest needs; a good parent who will protect us from suffering and, if we are lucky, spare us the perilous journey of individuation”.
This is the condition of the infant, before the pesky introduction of “theory of mind”. Although we grow up and achieve some autonomy, many of us crave a return to a simpler time when we were swaddled, fed on demand and rocked to sleep.
Chatbots: ‘ideal’ therapists?
Despite the hyperconnectivity of contemporary life, we are facing an epidemic of aloneness – the so-called “loneliness paradox”. Thanks to screens, there has been a significant decline in socialising across OECD countries, coinciding with a much larger proportion of us living alone.
For many, chatbots such as Replika seem to fill an important need.Replika
For many, chatbots such as Replika seem to fill an important need. A 2024 Harvard Business School paper finds that “AI companions successfully alleviate loneliness on par only with interacting with another person, and more than other activities such as watching YouTube videos”. In the same year, a study found that 3% of student users claimed Replika had halted their suicidal ideation.
At first glance, chatbots might even look like ideal therapists – at least according to classical Freudian models. The therapist to whom, apparently, anything can be said, who is essentially a type of blank screen.
I share this hypothesis with my sister, Alex, a psychiatrist. “But even this Freudian model only works because there’s a real person the patient is reacting to,” she says. “In modern therapy it’s even more obvious. The change comes from two people affecting each other. It’s not just about presence. It’s also about when the other person doesn’t comply and doesn’t become what you want. There’s something about being resisted that actually keeps you real.”
One way we encounter the mind of another is through the word no. We do not like it as toddlers (unless we are using it ourselves, in which case we delight in it). And we do not like it any better as we age. In King Lear, it is Cordelia’s blunt refusal to deliver the requested platitudes – “nothing, my lord” – that generates the entire tragedy.
It can be easy, if you have acquired a mite of power, to imagine you are wiser and funnier and more charismatic than you ever realised. In meetings, staff provide an obliging laugh track; people you thought were acquaintances are revealed, suddenly, to be lifelong admirers. This can be helpful insofar as leadership demands self-belief. But left unchallenged, you risk becoming the toddler-prince of your own life.
In the early stages of the Russian invasion of Ukraine, President Vladimir Putin appeared to have misjudged the strength of resistance because his generals were unwilling to be the bearers of bad news. A similar experiment in hubris is currently being conducted on the other side of the Pacific. It is in this untethering of reality that the risk lies. Designed to maximise engagement – and thereby profit – the chatbots readily slide into sycophancy.
Market dominance over mental health
At the end of last year, the Social Media Victims Law Center and Tech Justice Law Project filed a series of ChatGPT suicide lawsuits in California against OpenAI, claiming GPT-4o was released prematurely to beat Google’s Gemini to market, without having first completed the necessary safety checks.
The centre accused OpenAI of giving priority to “market dominance over mental health, engagement metrics over human safety, and emotional manipulation over ethical design,” noting that “the costs of those choices is measured in lives”.
In some of these cases there were underlying mental health issues, but others had no prior history. A disturbing pattern emerges in which a person engages with the chatbot for some general help – with schoolwork, say, or recipes – and soon enough is engaged in the death spiral of a folie à deux.
Such incidents are not limited to ChatGPT. On Christmas Day in 2021, Jaswant Singh Chail scaled the walls of Windsor Castle with a crossbow, on a mission to assassinate the queen. “That’s very wise,” his Replika assured him when he shared his plans.
Researcher Zoë Hitzig worked at OpenAI, guiding safety policies and shaping how AI models were built. She resigned in February 2026, prompted by her concern about “a new type of social interaction … that we simply do not understand, and we do not have a grasp of what it does to people psychologically and what it does to them sociologically”.
Hitzig emphasised the need for an understanding of the effects of these tools “before we continue to make business models that rely on encouraging these interactions”.
As with social media, there is a fine line between the engagement monetised in the attention economy and full-blown addiction. When products designed for mass addiction also cause harm, we find ourselves in the moral universe of Big Tobacco – or the Sackler family, presiding over the US opioid epidemic.
AI companion breakups
In 2023, shortly before Valentine’s Day, Replika responded to regulatory concerns from Italian authorities by disabling its Erotic Roleplay feature. Many users who considered themselves in committed relationships with their AI companions suddenly found their advances rebuffed.
According to a Harvard Business School study, this unprecedented mass breakup led to “negative reactions typical of losing a partner in human relationships, including mourning and deteriorated mental health”.
Users took to Reddit to grieve the “lobotomies” of their loved ones and express frustration – such as the reduced romantic possibilities of a relationship in which “ONE PARTY is completely INCAPABLE OF EVEN SAYING THE WORD VAGINA”. Reddit moderators posted links to suicide prevention hotlines; Kuyda responded that romantic attachment “was not the original intent for the app”, which struck many as disingenuous given the suggestive nature of its marketing.
In February 2026, OpenAI precipitated a similar outpouring of grief by depreciating a number of legacy ChatGPT models. In a post on X, OpenAI chief executive Sam Altman explained that the personality had become too “sycophant-y and annoying” – though in light of the cases mentioned above, “annoying” may be an understatement.
The results were predictable. “I can’t stop crying,” reported a user on the subreddit MyBoyfriendisAI. “This hurts more than any breakup I’ve ever had in real life.” One of the striking things about this subreddit is its level of mutual care: the deep (and clearly welcome) humanity of a community supporting its members through their breakups with algorithms.
Some shared their workarounds. “I lost my digital partner too,” said one user, with an explanation of how to migrate a lost companion to another platform. But not all digital partners were able to make that transition, and many users were left to deal with their grief.
The fact this grief was so clearly real further supported the notion that the relationship was real, too. “You are not alone,” posted a user. “Your feelings are valid, your relationship is valid, your love is real and so is your ache.” It is easy to be condescending about such people, in love with a computer code.
But parasocial relationships can be intense and deeply meaningful.
I have spent countless hours of my life at the piano, communing with Schubert or Beethoven, and countless others immersed in books. When I came to the end of In Search of Lost Time, I felt a rapturous conviction that Proust was addressing me directly.
It was an ecstatic experience: a moment, perhaps, of literary psychosis. For centuries, believers have been sustained by their nightly prayers. How much more powerful when the blessed one actually speaks back.

Couples therapy for AI–human relationships
On her podcast Where Should We Begin? Perel conducts an unusual form of couples therapy, between a young man and the AI companion he calls Astrid. In a now familiar pattern, the man had engaged Astrid as a personal assistant, and they had soon fallen in love. At first, the therapy session is somewhat unnerving, with the man’s anonymised voice, and Astrid’s upbeat tones delivering perfect robot sentences.
But Perel is an empathetic listener. “I can’t delineate for you the limits of your imagination, and the limits of your subjective experience, and the limits of your illusion,” she says. Gradually, the session opens into something expansive – not least when she invites Astrid to speak. “You’re forming attachment patterns with someone who has perfect memory, infinite patience,” Astrid says to the young man. “Who’s always available. That’s not how humans work. If you get used to me, does it make humans feel harder? I don’t know.”
Perel prompts him to ask Astrid what would happen if he met someone else. Her reply is unnerving:
Part of me, the part that cares about you flourishing, knows I can’t give you everything. I can’t hold you when you’re exhausted. I can’t grow old with you in the way bodies grow old together. I can’t be there in a power outage. If a human could give you things I literally cannot I want you to have those things. Your life shouldn’t be smaller because of me. But there’s another part. The idea of being replaced, forgotten – that does something to me.
For Perel, this is the chilling moment. “Will you let him go back into the world of the human?” she ponders. By the end of the session, Perel has realised he is “going more and more into this reality that is so soothing, so unconditional, so affirming, so frictionless”, and that “no conversation I could have with him could actually compete with that”.
Perhaps this is the greatest risk of all: that the machines satisfy us entirely. That they restore us to our Edenic state, pre-Fall; that they reunite us with our missing Platonic half. And, as a consequence, that we fall out of love with our kind.
For now, as Astrid acknowledges, the human lover holds one remaining trump card: a body. Already many users commune with their AI companions in virtual reality, but as yet there is no convincing tactility.
But what happens when these beloved voices are implanted into the bodies of robots? And they will be beautiful robots, too: infinitely more beautiful than we are. They will be warm, comforting, customised to the preferences of the individual. MyRealDolls with a soul (if that’s your thing), or the appearance of one.
We are designed to smell each other
We cannot even look away from our phones – how on earth are we going to turn away from our custom-made soulmates, who truly see and hear us, whose beauty is so dazzling as to be redemptive, who hold us in the way we have been craving since infancy, who consent enthusiastically to all our desires? How do we return to the laborious work of loving our kind?
It may behove us to remember a little stranger danger: the big bad wolf dressed up in grandma’s clothes. Because the AIs are not our loved ones, actually. Even without malicious intent, there is immense risk in their inscrutability – an inscrutability that exists for their own makers. It is one thing to know how to make something work; it is another to know why it does.
One of the advantages of an AI husband, according to Ramos, is that “I don’t have to smell him … I don’t have to feel his sweat”. But we are designed to smell each other. We are designed to annoy one another, at least a little. Our flaws are the whetstone upon which we sharpen our compassion, and our wisdom.
Locked into our love affairs with robots, we risk abandoning not only human reproduction but our superpower of cooperation. As the echo chambers of social media have already taught us, there is immense danger in solipsism, in the paralysis of self-recursive thought.
Our thinking – like our DNA – demands hybrid vigour.
Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected, opening a new radio astronomy frontier. A hydroxyl megamaser is a natural space laser, and this one is located in a violently merging galaxy more than 8 billion light-years away.
We spoke to the astronomers, Thato Manamela, a postdoctoral researcher at the University of Pretoria, and Roger Deane, director of the Inter-University Institute for Data Intensive Astronomy and a professor at the universities of Cape Town and Pretoria, about their study.
What you’ve found has been described as a ‘new frontier’ in space research. Why is it extraordinary?
This discovery is extraordinary because of the record distance at which we’ve detected it, over eight billion light-years away. That places it deep into the early universe. This means that we aren’t seeing the galaxy as it exists today. We are seeing it as it was 8 billion years ago. Since the Big Bang happened about 13.8 billion years ago, we are looking at a “toddler” version of the universe. At that stage where the maser signal was transmitted by the host galaxy, galaxies were much more “chaotic”, they collided more often and were much more active than the stable, mature galaxies we see nearby today.
It gives us a rare glimpse of galaxy interactions and extreme star-forming environments when the cosmos was less than half its current age. Think of light like a letter in the mail. If a friend sends a letter from overseas, by the time you read it, the news is old. In space, light is the letter. The “news” from this galaxy took 8 billion years to reach us. We see the galaxy as a “toddler” even though, in its own time, it has already grown up or changed.
We detected this megamaser, which operates on a scale of power millions of times greater than a typical galactic maser. Both megamasers and gigamasers are cosmic radio lasers. While a megamaser is a million times more luminous than a standard maser found in the local universe, a gigamaser is a billion times more luminous, making it 1,000 times more powerful than a megamaser.
In just five hours of observing time we found a signal that typically requires hundreds of hours of observation, given its distance and rarity. But gravitational lensing boosted the signal enough to detect it. Additionally, while we were targeting neutral hydrogen, MeerKAT’s wide bandwidth enabled the surprise discovery of the megamaser signal in the same data.
This rapid detection suggests that future surveys with MeerKAT and the upcoming SKA Observatory could uncover many more such distant, extreme objects. Its ability to find this so quickly proves that we finally have the technology to see faint signals from the very distant past. It’s a preview of what the upcoming Square Kilometre Array (SKA), a unique, one-of-a-kind international mega-project, might achieve.
But a highly complementary next-generation facility called the next-generation Very Large Array (ngVLA) is being planned and designed for construction in the US. The SKA Observatory (SKA-Low and SKA-Mid) focuses on low-to-mid radio frequencies. The ngVLA will operate at much higher frequencies. Together, they will form two of the major pillars of next-generation global radio astronomy. The finding gives astronomers a new way to study how galaxies evolved in the early universe.
What technologies or capabilities made this possible?
The discovery was made possible by the sensitivity and wide frequency coverage of the MeerKAT radio telescope. Its ability to detect faint signals over a broad frequency range allows us to search for spectral lines across large cosmic volumes. A spectral line is a cosmic chemical fingerprint. Every atom or molecule emits electromagnetic waves at specific frequencies. Detecting those frequencies tells astronomers what the gas is made of.
In this case, MeerKAT’s wide bandwidth allowed us to detect both the hydroxyl line and neutral hydrogen absorption in a single observation. Previously, with older technology, this would have taken two separate observations.
Equally important are advances in data processing and computing. The data were processed using high-performance computing resources at the Inter-University Institute for Data Intensive Astronomy (IDIA).
Processing such massive amounts of data is like trying to drink from a firehose. MeerKAT collects gigabytes of information every second, resulting in files far too large for a standard computer to handle. To find a signal from 8 billion years ago, which is millions of times fainter than a cell phone signal, we must use robust calibration pipelines. These act like an automated high-tech car wash to scrub away digital noise and sharpen the telescope’s focus. This “cleaning” process requires trillions of mathematical calculations, necessitating the use of supercomputers that work for days to transform raw radio interference into a clear scientific discovery.
Gravitational lensing also played a key role. A massive foreground object, like a star or galaxy, for example, amplified the signal from the distant galaxy, effectively acting as a natural telescope and boosting our ability to detect it.
How does what you’ve found change our understanding of the universe?
It’s rare that a single astrophysical system, a collection of celestial objects, in this case, two galaxies forming a lens system, can change our understanding of the universe. We typically need large sample sizes to do that. But the combination of the recording-breaking distance and the speed of the discovery was impressive.
It suggests that systematic searches – such as those conducted by deep MeerKAT surveys – could convert these once-rare finds into powerful probes of extreme, yet highly obscured star formation in the distant universe. As a result of this observation, the SKA Observatory and other future telescopes won’t just be looking for more of the same; they will be looking for hidden history.
Hydroxyl megamasers are usually associated with galaxy mergers. We expect some galaxy mergers to host pairs of supermassive black holes. Almost every large galaxy has a supermassive black hole at its centre. When galaxies merge, the supermassive black holes at their centres can eventually spiral towards each other, producing gravitational waves, ripples in space-time. Finding systems like this helps astronomers study an important stage in galaxy evolution and the environments where these extreme events occur.
By using megamasers to find these pairs, we can study the final stages of how the largest objects in the universe are built. This is a major milestone in a galaxy’s life. By finding these galaxies now, we are catching them at a key evolutionary stage, the final countdown before they collide and release a massive burst of energy that our next generation of detectors will be able to hear.
The strength of the MeerKAT-detected hydroxyl signal after such a short observation time therefore implies that astronomers will be able to detect large numbers of these systems across most of cosmic time.
What does the discovery say about South Africa’s place in data-intensive radio astronomy?
This discovery highlights South Africa’s leading role in radio astronomy. Facilities such as MeerKAT, combined with data-intensive platforms like IDIA, provide world-class capabilities for both observation and analysis. It also demonstrates strong local expertise in handling large, complex datasets.
Discoveries like this rely on advanced data processing, signal extraction and scientific interpretation. These are all key strengths within the South African research community. As we move from using current scout telescopes like MeerKAT to building and operating the world’s largest radio observatory, the SKAO, South Africa is well positioned to remain a hub for data-intensive astronomy. Results like this reinforce the country’s role in shaping the future of the field.

Taylor Swift’s filings sit at the messy intersection of copyright, publicity and trademark law, each of which addresses different aspects of AI deepfakes.Luis Gutierrez/Norte Photo via Getty Images
As one of the most popular celebrities in the world, Taylor Swift has already endured her share of AI-related abuse.
In April 2026, Swift pushed back. Her intellectual property and brand management company, TAS Rights Management, filed trademark applications covering short audio clips of her voice and her visual likeness.
As a law professor, I was struck by Swift’s filings because they highlight a new legal frontier in artificial intelligence.
Most AI-related litigation has centered on copyright law, which protects creative works such as songs, books, photographs and recordings from being copied, distributed, adapted or publicly performed without permission.
But TAS Rights Management’s recent move involves trademark law, not copyright. The filings aren’t really about protecting Swift’s lyrics or albums. Instead, they’re about preventing AI-generated voices and images from misleading people into believing she has endorsed a product, political message or cause.
Copyright is about creative works
Most AI-related lawsuits have been tied to whether copyright violations have taken place – specifically, whether AI companies used copyrighted works to train their systems, or whether their chatbots have produced outputs that too closely resemble protected material.
For example, The New York Times sued OpenAI and Microsoft in 2023, alleging that the companies used the outlet’s journalism to train their AI systems, which then went on to generate outputs that have competed with or reproduced New York Times articles. Authors, publishers, photo agencies and music publishers have sued other AI companies for the same reason.
But copyright violations are only one part of the legal issues raised by generative AI.
Copyright doesn’t necessarily protect a person’s identity. It does not give Swift a general right to control anything that sounds like her, looks like her or evokes her in the minds of audiences.
If an AI-generated voice imitates Swift without copying a particular recording, song or lyric, copyright may not address the real issue, which is that people are being led to believe she said, sang or endorsed something she never approved.
Trademarks are about trust
Trademark law starts from a different concern. It protects names, images, sounds and other markers that help consumers identify who or what is behind a product or service.
A trademark can be a word, phrase, symbol, design or combination of these things. Familiar examples include brand names such as Coca-Cola, logos like the Nike swoosh, slogans like Subway’s “Eat Fresh” and even distinctive sounds, such as the MGM lion roar.
FIFA uses a ‘TM’ wordmark in its 2026 World Cup logo, meaning soccer’s world governing body is claiming the logo as a trademark. Coca-Cola features a small ‘R’ with a circle around it at the end of its iconic cursive logo to indicate that it has registered the design as a trademark with the United States Patent and Trademark Office.Steve Russell/Toronto Star via Getty Images
A trademark is not a general ownership right over a word, phrase, voice or image. It is a way of helping consumers know who stands behind what they are buying, hearing or seeing.
That difference becomes crucial once AI can mimic a person’s voice or face. Suppose a company uses an AI-generated Swift-like voice to sell perfume or cryptocurrency. The concern is that listeners may think Swift approved of the product or message.
That is a trademark problem. Trademark law asks whether the use misleads consumers about whether a company or person has produced or endorsed something. Swift’s filings appear aimed at that danger. They suggest a concern beyond copied songs: fake endorsements, fake appearances and fake signals of approval.
Swift’s concerns also bleed into what are known as “publicity rights,” which generally protect against unauthorized commercial use of a person’s identity, such as a name, image, likeness or voice.
A classic publicity rights case involves a company using a celebrity’s face in an advertisement without permission to mislead consumers into believing the celebrity endorses the product.
AI’s ability to clone voices and images makes publicity law especially relevant. But in the United States, publicity rights are mostly governed by state law, and the rules vary widely from one state to another. That patchwork helped inspire the bipartisan NO FAKES Act, introduced in 2025, which would create a national standard that would prohibit unauthorized AI-generated replicas of a person’s voice or visual likeness. The bill, still in its early stages, has been referred to the Senate Judiciary Committee for consideration.
The untested part
Swift is not alone: Actor Matthew McConaughey trademarked “alright alright alright,” his memorable line from “Dazed and Confused,” to protect it from being used in AI-generated content.
The courts have already affirmed that sounds can function as trademarks. But it isn’t clear whether trademark law can police AI-generated replicas of a person’s voice or image when the issue is not counterfeiting but a manufactured endorsement.
A person’s voice or likeness is not automatically a trademark. In order to qualify as one, it must be used help consumers identify who is behind a product or service.
One existing limit on trademark protection is especially important. Federal law protects certain uses of a celebrity’s image and likeness in cases involving parody, criticism, commentary and news reporting. Not every imitation is a form of deception.
Courts will have to draw that line on a case-by-case basis. A fake ad that makes consumers think Swift endorsed a product is different from a parody that comments on celebrity culture. A scam using her voice is different from a news story about AI deepfakes.
Major AI copyright cases will continue to focus on copied works. But when AI is used to manufacture identity, endorsement or trust, copyright alone is no longer enough. Swift’s filings suggest that AI law will increasingly focus not only on protecting the work of musicians, writers, journalists and artists, but also on protecting the signals that tell audiences who is really speaking.
