I am a huge fan of Dale Carnegie and mention him in pretty much every interview I give. Carnegie was American, born in 1888, raised on a farm, and wrote one of the greatest self-help books of all time, How to Win Friends and Influence People. The book has now sold over 30 million copies worldwide.

I first came across his work when I was about 10 years old and read this book on showmanship and presentation….

According to Edward Maurice, it’s helpful if magicians are likeable (who knew!), so he recommended that they read Carnegie’s book. I still have my original copy, and it’s covered in my notes and highlights.

One of my favourite — and wonderfully simple — pieces of advice is to smile more. Since the book was written, psychologists have discovered lots about the power of smiling. There is evidence that forcing your face into a smile makes you feel better (known as the facial feedback hypothesis). In addition, it often elicits a smile in return and, in doing so, makes others feel good too. As a result, people enjoy being around you. But, as Carnegie says, it must be a genuine smile, as fake grins look odd and are ineffective. Try it the next time you meet someone, answer the telephone, or open your front door. It makes a real difference.
In another section of the book, Carnegie tells an anecdote about a parent whose son went to university but never replied to their letters. To illustrate the importance of seeing a situation from another person’s point of view, Carnegie advised the parent to write a letter saying that they had enclosed a cheque — but to leave out the cheque. The son replied instantly.

Then there is the power of reminding yourself how much the people in your life mean to you. Carnegie once asked the great stage illusionist Howard Thurston about the secret of his success. Thurston explained that before he walked on stage, he always reminded himself that the audience had been kind enough to come and see him. Standing in the wings, he would repeat the phrase, “I love my audience. I love my audience.” He then walked out into the spotlight with a smile on his face and a spring in his step.
This is not the only link between Carnegie and magic. Dai Vernon was a hugely influential exponent of close-up magic and, in his early days, billed himself as Dale Vernon because of the success of Dale Carnegie (The Vernon Touch, Genii, April 1973). In addition, in 1947 Carnegie was a VIP guest at the Magicians’ Guild Banquet Show in New York. Here is a rare photo of the great author standing with several famous magicians of the day (from Conjurers Magazine, Vol. 3, No. 4; courtesy of the brilliant Lybrary.com).

If you don’t have a copy, go and get How to Win Friends and Influence People. Some of the language is dated now, but the thinking is still excellent. Oh, and there is an excellent biography of Carnegie by Steven Watts here.
Conservatives hate science. This is why they slashed budgets to science agencies, and put lunatic ideologues in charge of the NIH, NSF, and the environment, with the clear intent to cut the knees out from under science education and policy. Jessica Knurick is precisely right on this matter.
You can also see it in the staffing of all of these critical science organizations.
It’s like science got pushed off a cliff when Trump took office.
Perhaps you would like me to reassure you that once we throw the rascals out and elect responsible politicians who respect the role science has played in American prosperity, we’ll just hire them back. No, sorry, this isn’t like rehiring workers at the Amazon warehouse. A science hire is accompanied by a large investment in equipment and personnel. I’m at a small liberal arts college; when I was hired here, I was also offered tens of thousands of dollars in startup money to set up my lab the way I needed to be able to do my work. I was dirt cheap. I’ve known colleagues who were offered hundreds of thousands of dollars, and even a few who got somewhere near a million dollars, to cover the ancillary costs of setting up a major lab.
It’s not as if a custom lab and technicians and instruments are sitting around waiting for someone with the expertise to do cutting edge research to show up. This stuff needs to be assembled at great cost to fill a need.
The people are also not generic tools you can swap in and out. We pay science staff peanuts for years, and we hang in there to do the work we love — we generally don’t have a massive financial cushion to weather heavy shifts in employment. Some of those laid off personnel are going to leave the country, looking for work in a nation that doesn’t disrespect science, while most are going to simply give up, get a job at that Amazon warehouse or switch to writing software. Their hearts are broken by the American science establishment. They’re not going to revisit this occupation shown to be willing to discard them if an orange moron gets elected or a con man with half his brain eaten by worms gets appointed.
That is a graph of disillusionment. It would take decades and a new generation to repair it, if we even had the will to bring science back. Given that the damage is being delivered right down to support for grade school education, don’t even count on a single generation being enough.
It’s not just a few people being let go. It’s the demolition of a cultural heritage of science.
My state is impressing the world with its communal cooperation and altruism. It turns out we’re just responding in a normal human way.
In sociology, there’s a term to describe this phenomenon: “bounded solidarity.” Alejandro Portes, a prominent sociologist at Princeton University, first introduced the term in a paper published in The Annual Review of Sociology in 1998. It’s used to describe when a community is bound by a crisis, and during this time, it can lead to extreme acts of altruism and kindness that aren’t usually seen in non-crisis times.
OK, nice of sociologists to provide a name for the phenomenon.
We are seeing this in Minnesota right now. Multiple media reports have highlighted the ways in which the community has come together. Volunteers are delivering groceries so immigrants can hide at home. People are raising money to help Minnesotans cover rent because they haven’t felt safe to go to work. People are taking each other’s kids to school, organizing shifts for people to stand guard and protect immigrants in their neighborhoods. As NPR recently reported, when a preteen got her period for the first time — a preteen who hadn’t felt safe enough to leave the house to go to school — a community rallied together and launched an underground operation to get her pads. Minnesotans have been braving the below-freezing cold to show up for protests and denounce the violence in their communities for weeks.
These acts of kindness and solidarity matter because it’s exactly what people need to move through a crisis, build resilience, and transform a community for the better. Daniel Aldrich, a professor at Northeastern University teaching disaster resilience, and a survivor of Hurricane Katrina, once told me that when it comes to a disaster, his research found that community-based responses are more successful than individual-based ones.
You mean like mutual aid? The antithesis of the rugged individualism this country usually promotes? We’ve been talking about that for a century or so.
It’s cold across much of the country. There’s snow and ice on the ground.
IT’S A CONSPIRACY!
At least, some stupid people are trying to imagine alien weirdness going on, including this desperate ignorance from Candace Owens, who thinks it’s artificial because it doesn’t melt at 30°F.
I looked at some of the comments. Many are trying to explain to her that the freezing point of water is 32°F, and that 30 is less than 32, and some mention that the temperature in Connecticut when she was horrified by frozen water was actually 25°F. Others are agreeing that yes, it’s a government or alien conspiracy.
Remember this when Candace Owens trots out another bizarre conspiracy theory. I think the lawsuit by Brigitte Macron against her is going to go well.
An ugly old white man (I can say it, I’m one of them) took a seat in the front row of an Ilhan Omar speech, and then jumped up, shouted something unintelligible, whipped out a syringe, and sprayed something unpleasant and bad smelling on her. Then he was promptly tackled.
That’s a metaphor for something — ineffectual, horrible person making a stink and trying to disrupt a democratic event. Even more appropriate is the response by Omar.
Omar continued to talk after the disturbance, commenting: “We will continue. These f****** a**holes are not going to get away with it.”
Exactly right. Say it!
“We’re going to keep talking … just give me 10 minutes. Just give me 10 minutes. I beg you,” Omar told a man, who appeared to be security. “Please don’t let them have the show.”
“Here is the reality that people like this ugly man don’t understand. We are Minnesota strong, and we will stay resilient in the face of whatever they might throw at us,” she continued.
“Everybody settle down. I’m going to finish my remarks. It is important for me to continue to lead my Democratic colleagues in demanding her (DHS Secretary Kristi Noem) resignation. And like I said, if she does not resign, we are going to introduce articles of impeachment.”
I like representatives who have a clear idea of what needs to be done, and Ilhan Omar has that power.
Daniel Phelps, who tracks attendance at Ken Ham’s cheesy roadside attractions in Kentucky, tells me that they’re in decline.
According to my monthly Kentucky Open Records Act (KORA) request, December Ark ticket sales were the lowest ever (with the exception of 2020 – during the Covid pandemic). In December 2025, the Ark sold 35,223 tickets, about 4,000 less than December of 2024. Of course, these ticket sales numbers don’t include lifetime pass members or children under 10. My summary of all available ticket sales numbers can be found below.
The December ticket sales number means that the Ark sold 652,342 tickets in 2025. These numbers indicate that the Ark will never come close to the 1.4 to 2.2 million attendees per year projected when the Ark was begging/shaking down Grant County, Williamstown, and Kentucky Tourism for perks including 100 acres of land for $2, $200K cash, reduced taxes, a $62 million bond, and $1.825 million dollars/year in sales tax rebates.
Because of massive donations, AiG and its shell companies are not in danger of collapse. They, however, aren’t doing as good as in previous years.
Yeah, no likelihood of imminent demise, unfortunately — I’m sure the leadership is living comfortably for the duration, and has no major concerns for the future, but they’re in a cult that demands the conversion of everyone in the country (the world!) to their weird apocalyptic doomsday religion. They must be hoping for some magical miracle, and it isn’t happening right now.
Perhaps of greater concern is that their cult of personality is led by a personality that isn’t propagating.
If you look at AiG’s website https://answersingenesis.org, more and more of the content is exclusively coming from Ken Ham himself. Most notably, no one appears to be a replacement for Mr. Ham if he ever retires. His onetime appointed successor, Martyn Iles somehow ended his employment with AiG and returned to Australia to form his own conservative ministry. There have been no official reasons given for this departure by either AiG or Martyn Iles himself (if you know, let us hear about it).
That’s a problem with authoritarian cults. They are ruled for life by unpleasant, weird people who alienate everyone around them, and maybe instill in them the ambition to be in charge on their own. I hope I outlive Ken Ham, because I’d really like to see the chaos that will follow on his death.

A Different Kind of Power: A Memoir (Macmillan) by Jacinda Ardern
Jacinda Ardern was the 40th prime minister of New Zealand, but the first to become an internationally recognised figure – certainly, Keith Holyoake and Robert Muldoon never appeared on the cover of Vogue. Ardern became an instant object of fascination because – at least when measured against her fellow national leaders, an overwhelmingly male, middle-aged-and-upwards and mostly somewhat dreary cohort – she seemed different: a 37-year-old woman of generally cheerful demeanour. As the title of her book suggests, Ardern also sees herself as different, in substance as well as style.
Ardern is, at the very least, a different kind of political memoirist. A Different Kind of Power is short on wearisome policy minutiae, and petulant score-settling. The book’s strength is that it depicts, very capably, the human experience of national leadership – its pressures and dilemmas, its drama and slapstick, its gravity and absurdity. The prologue captures the moment amidst the post-election negotiations which brought her to power in 2017 when Ardern discovers she is pregnant.
After which, Ardern starts at the start: her childhood in small rural towns where her father served as a police officer. Ardern clearly believes this was the making of her: the conscientious, empathetic child becoming a prime minister of similar qualities (if the book has one minor but recurring fault, it is an over-emphasis on the “if anything, I just care too much” schtick).
Ardern grows up a Mormon, but drifts from the church in her twenties. It is always illuminating to discover why people reject the faith in which they are raised. It is not an easy call, risking as it does the ostracism of family, friends and community.
Her departure from the Church of Latter-Day Saints is admirable in motivation and execution. She reaches a point at which she cannot accommodate both her belief in equal rights for gay people and the LDS’s institutional animus towards them – but she moves on without bitterness, while maintaining admiration for the good the Mormons do, and the good people among them. She also drily notes that the experience of knocking on strangers’ doors, trying to interest them in new ideas while they’re trying to eat dinner or watch the match, is excellent practice for becoming a campaigning politician.
The most gripping sections of A Different Kind of Power are those that recall the two worst moments of her premiership – neither of which any incoming prime minister of New Zealand would have imagined likely. One was the predicament that confronted everybody in a job like hers in 2020. Though Covid-19 menaced New Zealand less than it did most countries – far-flung islands had a considerable advantage – its prime minister still faced excruciating choices. “For each decision we made,” Ardern writes, “hundreds of new ones presented themselves.” This summary of the infernal complexity of politics would be lost, regrettably, on the sorry mobs of social media-addled bozos who besieged New Zealand’s parliament, having convinced themselves that they were subjects of a tyranny, as opposed to the supernaturally fortunate citizens of a lavishly blessed nation. (“At one point,” Ardern deadpans, “I even saw the glint of literal tinfoil hats.”)
The other defining crisis of Ardern’s term was the terror attack on two mosques in Christchurch in 2019, in which 51 people were murdered and dozens more injured, by a lone maniac. Ardern deserved the plaudits she received for her calm and thoughtful leadership in the hours and days immediately following this atrocity, but as she tells it here, her initial reaction was less composed. “All of the confusion and frustration I felt,” she writes, “turned into one singular emotion: blinding rage.” A pertinent reminder that despite the perennial voters’ complaint about politicians not saying what they actually think, there are times when it really wouldn’t be helpful, or appropriate.
When Ardern stepped down in 2023, citing exhaustion, cynics claimed that her polling ahead of that year’s election may have been more of a factor. She was, by this time, one of those leaders vastly more popular abroad than at home, and her Labour Party were duly clobbered. But if she was tired, she was entitled to be. The great service A Different Kind of Power performs is that it reminds us that politicians are people – people to whom we give impossible jobs, and of whom we demand impossible results.

In We, a dystopian fable written in 1921-22 and set in the 26th century, the Russian author Yevgeny Zamyatin imagined a totalitarian regime called “OneState”. The buildings in this urban civilisation are uniformly constructed out of clear glass bricks, through which the sinister “Guardians”, its law enforcers, can monitor their subjects’ every move. As the automaton-like protagonist, D-503, puts it, “We live in broad daylight inside these walls that seem to have been fashioned out of bright air, always on view.” The use of glass is thus a key component of the state’s attempt to annihilate the individual personality in the machine-like collective. Zamyatin’s vision would influence George Orwell’s 1984.
At the turn of the 20th century, the introduction of machines that could manufacture large-scale flat glass led to the increasing use of glass in architecture – for better or worse. Among the vitro-optimists was Paul Scheerbart, an eccentric German writer and critic who produced both a treatise and a novel on the potential of glass architecture. The novel, entitled The Gray Cloth and Ten Per Cent White (1914), imagined a fantastical mid-20th-century society in which superstar architects travelled around the globe in airships, admiring their colossal buildings of coloured glass.
A century after Zamyatin and Scheerbart, glass has, to an extent unprecedented in human history, become ubiquitous not only in architecture but in technology, industry and daily life. Indeed, 2022 was the United Nations International Year of Glass. The official booklet proclaimed a new Glass Age and highlighted the material’s importance in areas including communications, biomaterials, energy generation, sustainability, healthcare and aerospace.
Despite its topicality, however, there is one field in which glass remains undervalued: contemporary art. Artists who work mainly in glass, especially if they actually handle the material themselves, have trouble getting their pieces accepted by the art world. “Glass is usually perceived as a traditional material for craft rather than for fine art galleries,” says Marieta Tedenac, a Prague-based conceptual artist who works in glass and other media.
This sort of attitude perhaps says more about the art world than it does about glass. Be that as it may, in the last few decades several artists, whether working alone or collaboratively, have laboured to demonstrate the potential of glass as an artistic medium – a means of free creative expression – and one which benefits from a combination of imaginative vision and inspiration, scientific and technical knowledge, and painstaking, skilful craftsmanship. Arguably, their achievements show that art in glass has a distinctive contribution to make to our uniquely glassy age.
Glass is certainly important for the digital world and Big Tech, most visibly through its use in computer and smartphone screens. This importance is reflected in the glass-heavy architecture adopted, for instance, in Apple stores. In 2013-14, Google even tried, unsuccessfully, to trademark the word “Glass” in a particular font for its “smart glasses”. It is thus surely significant that when Apple wanted to commission a public artwork for the Apple Park outside its headquarters in Cupertino, California, the proposal it selected in 2021, submitted by the Scottish conceptual artist Katie Paterson and the architectural studio Zeller & Moye, was made of glass.
Completed in 2023, Mirage is an installation of 448 glass columns, each standing two metres tall and weighing 90kg, and varying in colour from deep green to mineral blue to near-transparent. It represents a monumental collaboration involving artist, architects, Apple staff, scientists and glassmakers, as well as sand sourced from 70 deserts around the world. The columns are arranged in a pattern of three wavy lines, which, from a drone’s-eye view, suggest “desert dunes”, according to the creators – or, on a more subversive interpretation, a pixellated corporate logo.
Mirage is full of ambivalence, ostensibly being constructed for the benefit of Cupertino’s citizens, but redolent, beneath the glittering surface, of Apple’s apparent ambitions for technological supremacy – in which glass plays an essential role.
One specific type of glass that has been used effectively in art is optical glass. Made with a range of specialised chemical compositions, it was originally developed for lenses and prisms, including in a military context, which needed to refract light precisely. In the 1960s, Václav Cigler, a leading Czech artist and founder of the Glass in Architecture department at Bratislava University, began experimenting with optical glass. He designed sculptures that were precisely cut, ground and polished to achieve brilliantly reflective surfaces. His pure, minimalist forms – an egg, a pyramid, a cone – distil the essence of shapes found in nature and architecture, functioning as almost mathematical focal points which encourage detached contemplation.
One of the reasons that the art world is suspicious of glass art may be the technical challenges involved in its creation. Some contemporary artists have an awkward relationship with the act of “fabricating” (or making) artworks, following current wisdom that what matters is choosing the material that best suits what the artist wants to say, rather than one that he or she has the most skill in manipulating. Yet this attitude may itself owe something to advances in digital technologies such as graphics, 3D printing and generative AI, compared to which, these days, a human’s ability to make things can seem less impressive. Not only are machines better at fabricating, but the virtual world has become ever more sophisticated and enticing. Why bother to make anything that will be subject to the laws of nature, when you could conjure up impossible objects on the screen?
Last year, Luca Curci Architects, an Italian firm, published the “Floating Glass Museum” project on its website. This quixotic museum, designed with the aid of AI, takes the form of a curved white building with fluorescent panes of glass that floats on a swimming-pool-like sea. Inside are rooms filled with large numbers of huge glass spheres. Some of the spheres even seem to float above the ground, in defiance of gravity – which AI had apparently not quite grasped at the time. It is pretty to look at, and yet the very ease with which scenarios like this can be produced, once the limitations of the empirical world are removed, arguably makes them less interesting.
To return to “reality”, the paradox of glass is that on the one hand it is so elusive, but on the other so tactile, heavy and difficult to handle. Glass can be shattered, even on a smartphone, and be transformed instantly from something smooth and self-effacing into something sharp and destructive that also does violence to the image within it. No wonder the breaking of a mirror has traditionally been associated with bad luck.
An example of an evocative aesthetic effect derived from breaking glass occurs in the 2022 film The Glass Onion, in which, in a climactic scene, the collection of clear glass sculptures belonging to a villainous tech entrepreneur is smashed by his guests – as though the sculptures’ entire raison d’être was their destruction.
The brittleness of glass, the risk of chipping or breakage that could annihilate a work’s perfection in an instant, doubtless contributes to its perception as a challenging, even off-putting artistic medium. On the other hand, this same quality can be used as a metaphor to express contemporary concerns. One example is in Stampede, a collection of clear glass animal paws, hot-sculpted by the New York-based artist Deborah Czeresko. The sculptures are carefully modelled on real paws, both live and stuffed, and include a range of species – bat, camel, mole, ostrich, platypus, penguin. With silent eloquence, the fragility of the material, together with its phantom-like transparency, reminds us of the ease with which animal species may be destroyed. Once gone, it would be as impossible to bring them back to life as to reconstitute a shattered glass paw from its fragments – which, since glass is an amorphous solid, will always be irregular and chaotic.
The rich versatility of glass, both as material and as store of imagery, is further exemplified in the work of the American artist Jon Kuhn, who makes sculptures in the form of geometrical solids containing hundreds of facets of glass that refract the light from within like tiny prisms. He does this by a time-consuming process of cutting and polishing segments of optical glass and then laminating them together in a complex structure.
It is a piece by Kuhn, if I am not mistaken, that appears on a table just behind the eminent philosopher and public intellectual Martha Nussbaum, in a photograph taken in 2017 and published alongside an interview in the New York Review of Books in 2021. The positioning creates a connection between the jewel-like interior of the glass and the clarity and sparkle of the sitter’s mind.
As the work of artists like Cigler, Czeresko or Paterson shows, in our new Glass Age, this material can no longer be dismissed as old-fashioned or suitable merely for craft. Instead, it can be an eloquent means of imaginative creation and self-expression.
In a world where our attention is increasingly occupied by images and events behind the glass screen, the material from which that screen is made, with its combination of smoothness and sharpness, liquidity and solidity, depth and surface, can remind us of how dependent we are, despite ourselves, on physical things.
It can thus function as an empirical and metaphorical barrier – the modern equivalent of a looking-glass – between the digital realm and our own. Finally, a key function of art in our image-conscious age is as status symbol and personality extension. In this respect, while some artists may still dismiss it as a medium, glass can surely give bananas, Lego bricks or even paintings a run for their money.

In February 2024, people across the US began placing orders for a plant that glows at night. The Firefly Petunia, sold by the synthetic biology startup Light Bio, looks like a regular white petunia by day – but in darkness it transforms, emitting a soft light, most visible in its flower buds. The first glowing plant was created in 1986, but it has taken 38 years for the technology to be enjoyed in people’s homes and offices.
Most people are interested in the beauty and novelty of the flower. But while the glowing petunias are aesthetically remarkable, they also demonstrate that “living light”, as it’s often called, can move beyond the lab into everyday environments. Most promisingly, bioluminescent and fluorescent plants have practical uses in agriculture. The light the plants emit can help us understand and combat complex threats to crops – including rot, pests and fungal disease – which are likely to deepen with the ongoing climate crisis.
Most of us have seen some instance of bioluminescence, which is defined as light made by living things, and occurs naturally in fungi and animals. Fireflies are the most obvious example, as well as deep-sea creatures and a handful of glowing fungi. The chemistry is straightforward enough: enzymes called luciferases act on small molecules called luciferins (sometimes with cofactors like ATP, an energy-carrying molecule), in the presence of oxygen. The reaction then releases energy as photons.
Fungi and animals have evolved to glow naturally for a variety of reasons. Fireflies emit light to attract mates and warn predators that they’re an unpleasant meal. It’s thought that the deep-sea lanternfish glows in order to blend in with the blue of the sea and avoid predators. In the case of fungi, however, scientists are still speculating. The leading theory is that the glow attracts insects, aiding reproduction and dispersal, which might be especially helpful in dark forest environments.
But plants don’t glow naturally; they never had to evolve that way. We humans have intervened. So how did we engineer these plants, and why?
The first glowing plants in the 1980s were only suitable for lab environments, and were mostly designed to study genetic processes. Bioluminescence can be used to provide a real-time indicator of plant development and stress response – all without harming the organism. Keith Wood, now chief executive of Light Bio, worked with the team that created the first glowing plant, by inserting a firefly bioluminescent system into a tobacco plant.
Bioluminescent systems from various insects, marine life and fungi can be inserted into plants, but there are important differences in how this is done and how it affects the glow. In some cases, scientists insert just the genes for luciferase, the enzyme that produces light when it reacts with luciferin, or introduce the luciferin chemically along with luciferase. This approach can make the plants glow, but the light usually lasts for a limited time, since luciferin is not produced inside the plant and must be replenished externally.
The next step, then, was to engineer plants to glow throughout their life. This involved designing plants to produce both luciferase and luciferin themselves by inserting the full set of fungal bioluminescent genes. Because these fungal systems use caffeic acid, which plants naturally produce, the engineered plants can run this light-producing reaction autonomously without needing outside chemicals, creating a sustainable, self-sufficient bioluminescent system. But the light emitted was still too weak and unstable for conditions outside the lab.
More recent work has adapted the mushroom genes so that they function better in plant cells and tissues, boosting brightness by up to a hundredfold.
Today, Light Bio focuses primarily on producing ornamental plants. “People are not only excited and surprised when they see a living plant glow in the dark, they’re often deeply moved,” Wood tells me. But the same technology has practical applications outside the lab.
It is being used, for example, in food safety contexts. Quality-control tests use enzymes and chemicals to help detect contamination in milk and meat. These tests measure the presence of ATP, which reacts with the luciferase added to the food products, triggering the chemical reaction that produces light. The amount of light generated is proportional to the level of ATP, which then shows the extent of contamination.
What about using glowing plants in agriculture? One avenue of exploration relates to pollination. Some researchers speculate that glowing cues might affect insect behaviour. For example, a faint bioluminescent cue at dusk might help nocturnal insects such as moths, which rely on colour and shape, to find flowers. Even adult fireflies, themselves pollinators, could be drawn to these flowers at night. If pollination can be encouraged, then this benefits farmers because it can lead to better fruit and seed development, resulting in improved crop yields. But this idea needs more testing outside the labs, with real crops and in real weather, with attention to the ecological side-effects.
For now, another kind of light-emission is yielding more concrete benefits for farmers: fluorescent plants. Like bioluminescence, fluorescence also makes living things emit light, but it can’t operate in the dark. A molecule absorbs incoming light and then re‑emits it at a specific wavelength. With the right illumination and filters, the signal answers back. In practice, this usually means using artificial light sources and optical sensors, since ambient sunlight alone is rarely enough to give a clear reading. In short, bioluminescence shines by itself, while fluorescence shines when asked.
The Californian biotechnology company InnerPlant engineers crops to fluoresce in patterns designed to be read with specialised optics, from the ground and from aircraft. Their commercial product is focused on fungal infections in soybeans. Sensors are planted in plots across a region, acting somewhat like towers in a mobile network. Farmers do not host or manage the hardware, rather they subscribe to the network. InnerPlant’s agronomists send weekly scouting reports during high-risk periods and send alerts by text and email when sensors confirm infection.
“It helps take the guesswork out of fungicide decisions,” said Sean Yokomizo of InnerPlant. “[Farmers] only have to take action when and where it’s needed, rather than spraying entire fields.” Farmers are pragmatic and want clear benefits, he said. Technology has to be low-risk and consistent to win trust.
As of 2025, InnerPlant’s network covers 50,000 acres across the Midwest US, including in Illinois, Iowa, Nebraska and South Dakota. They plan to increase the network to cover more than half a million acres in 2026, and to add insect detection in soybeans in 2027, followed by a corn fungal sensor. The company is also looking into satellite use, with the aim of improving their large‑scale visibility.
Whether or not InnerPlant succeed in their plans, other companies are likely to take advantage of these new technologies. Fluorescent technologies may be particularly helpful in coping with climate change, which is already leading to unpredictable weather patterns. These include raised temperatures and humidity – conditions in which fungal disease can escalate rapidly. An early fluorescent signal lets a grower treat the right block before spores spread further across crops. Blanket “just in case” sprays can become the exception, targeted passes can become the norm, and costs fall – as does the chemical load that runs into streams.
Fluorescence can also help to guide watering practices – which is especially important in times of drought, or where water is expensive or scarce. Plants shift their fluorescent signatures when stressed, often before leaves wilt. If you can see that change early, irrigation moves from routine to need, which saves energy and helps prevent salt build-up in soils. It’s useful for monitoring nutrients, too. If low nitrogen shows up as a clear map rather than a hunch, variable-rate equipment can treat poor zones and skip healthy ones. Yields hold and, again, excess fertiliser stays out of rivers.
While fluorescent plants offer a powerful tool for monitoring plant health, they come with significant limitations that justify continued interest in bioluminescent systems. Fluorescence relies on external light sources to excite the fluorescent proteins, meaning it requires specific field conditions, special optics and a clear line of sight to detect the signal accurately. These requirements can make it challenging to implement widespread, real-time monitoring in open agricultural fields.
In contrast, bioluminescent plants produce their own light through biochemical reactions, offering the potential for continuous, autonomous signalling of plant health or stress without external illumination. This intrinsic glow could enable easier, more flexible monitoring in diverse environments and at night, providing a unique approach that fluorescence alone cannot currently offer.
Daniel Voytas, a professor at the University of Minnesota and a leader in plant genome editing, says we shouldn’t give up on bioluminescence as a developing field that could have future applications in agriculture.
Along with engineering plants using the fungal bioluminescent system, researchers are also making good progress with insect systems. “The use of insect luciferases as reporters has been enormously valuable for plant biotechnology research, and I expect their role will continue, if not expand,” Voytas told me. “These are primarily research tools rather than traits in themselves, so their direct impact on agriculture and food security is likely to remain limited compared to other biotechnological approaches,” he acknowledged. But while achieving consistently high levels of luminescence has proven a significant challenge, the science is advancing.
There are many hurdles to overcome, for both bioluminescent and fluorescent technologies. Farms are dirty and unpredictable places. Light signals have to be bright and specific. Models need to be able to tell the difference, for example, between light emitted due to heat stress and light that indicates infection. The challenge is producing a sufficient number of plants that are bright enough to be useful. And even if luminescence improves, the trait still has to deliver under sun and heat, and earn its keep across a season. Some farms can also be reluctant to try new technologies. Mistakes in agriculture can be costly. A false positive, for example signalling disease, could be a huge waste of time and money.
Regulators will continue to ask hard questions, too. There’s no sign yet that the trait that causes plants to glow can spread by pollen, but these questions about gene flow are sensitive, and must be carefully tested and monitored. If the ability to glow draws on more of a plant’s metabolism (in other words, the energy available to them) then it may slow their growth, or ability to produce seeds or fruit.
Public acceptance is important too, given many people have negative attitudes towards genetically engineered crops. Light Bio believes that their ornamental plants can play an important role in shifting public perception. “Crop development through genetic manipulation is vital to global food security,” Wood said. “By giving the public a tangible, positive experience with a glowing plant, we believe we can help build familiarity and trust.”
When I asked him about the future, he said he expects brighter and more varied glowing plants to be developed over the next decade. “We’re improving the genetics, and we’re improving the methods of production,” he said. “I expect we’ll get brighter plants, more robust plants.”
Meanwhile, bioluminescence and fluorescence will continue to allow scientists to study plant physiology, with discoveries feeding back into knowledge around how to develop better and stronger bioluminescent traits, creating a positive cycle of learning and development.
Yokomizo of InnerPlant believes that advances in the study of the genetic processes of plants, combined with the use of bioluminescent and fluorescent traits in crops out on the field, represents a revolutionary opportunity in farming. “Data from plants has always been the missing component all the way back to the beginning of agriculture,” he said. “Finally having that critical data will change farming practices in a very fundamental way, just as the Green Revolution did.”
He’s referring to rapid changes that took place in farming in the mid-20th century, including the development of synthetic nitrogen fertiliser. There was also progress in breeding plants in order to create hybrid seeds, known as high-yielding varieties, which are more responsive to fertilisers, and better at adapting and resisting disease. All of this triggered major economic growth in agricultural regions worldwide.
It’s a bold comparison, and it should be treated as speculative. We don’t yet know whether bioluminescence and fluorescence will have revolutionary effects on the future of agriculture. It is more cautious to say that clear, early signals can help reduce waste and protect yields.
For now, bioluminescence and fluorescence will remain a powerful research tool, and field deployment should expand as engineering advances. In the meantime, ornamental plants serve a quieter purpose. They show biotechnology as something beautiful, not only as a risk. It’s a shift in perception that can help us imagine what could come next…
In late summer, a soybean grower gets a text: four fields crossed a fungal threshold overnight. The sprayer rolls that day, but only across those blocks. Time, money and effort are saved, and environmental impacts are reduced.
At a nearby farm, nitrogen goes only where the signal shows deficiency. The field map turns patchy and precise, which is how real land behaves.
At the packhouse, a bioluminescent signal flags contamination before a pallet of bananas is loaded onto a ship. The win is invisible but crucial, as prevention usually is.
Most of the time, we won’t see the light with the naked eye. But some day in the future, it may be a common occurrence to drive past a farmer’s field at night and notice a faint but magical glow.

It’s time for some obscure magic and music hall history.
I’m a fan of a remarkable Scottish conjurer called Harry Marvello. He was performing during the early 1900s and built a theatre in Edinburgh that is now an amusement arcade. I have a previous post on Marvello here and have just written a long article about him for a magic history magazine called Gibecière (the issue is out soon).

The Genius Myth (Jonathan Cape) by Helen Lewis
In the 1980s, when high-IQ societies like Mensa were surveyed about the term they thought best applied to their members, they didn’t gravitate to the term “geniuses”. More than any other, they liked the word “outsiders”.
This is one of many revealing facts from Helen Lewis’s new book on the concept of “geniuses”, whose subtitle warns us of “the dangerous allure of rebels, monsters and rule-breakers”. For a genius to linger in the public consciousness, says Lewis, it is best if they are perceived as abnormal and therefore special in some way. Disgraced psychologist Hans Eysenck, who specialised in the area, said geniuses have to be mad, psychopathic or at least a bit odd to live up to the stereotype.
The word “genius” conjures up a whole host of connotations, from Einstein through Hawking to Picasso. (Historically, most recognised geniuses are men, although Lewis devotes a chapter to the overlooked women who supported some of them to do their best work.) You could make an argument for the term being more of a hindrance than a help; that we would be better off disposing of it entirely. Lewis doesn’t go that far. “We need the idea of genius – the demigod, the superhero, the shaman,” she writes. “We need stories to make sense of the world.”
What is the story of genius, then? The way Lewis frames it, it is close to the study of fame. Some people are brilliant and may deserve to be recognised as geniuses. But the term, in popular culture at least, isn’t limited to an objective definition, nor can it possibly conform to the rigid measurements of an IQ test. A genius isn’t a technical benchmark; it is a constellation of factors, which together scratch the itch of their particular age. “Societies anoint exceptional people as geniuses to demonstrate what they value,” Lewis writes.
Through various case studies (The Beatles, Tolstoy, Edison, Musk), Lewis applies her microscope to the patchwork of factors that created the tapestry of genius. She tells us that one of the reasons that California became the technology centre of the universe was that the eastern states in the US had employment contracts that let bosses sue their employees for defecting to a rival company. “But California did not, so its companies benefited from a constant exchange of skills as the best engineers moved around more freely.” This is a perfect example of “scenius”, a phrase coined by Brian Eno – that it is impossible to separate an individual’s genius from the environment in which they operated.
There are twin, almost contradictory, impulses in us when it comes to genius: one is that we let geniuses get away with terrible behaviour; the other, which Lewis calls the “deficit model of genius”, is that we expect and may in fact want them to suffer. Lewis may not be able to answer the question of why and how we cling to these convictions – here perhaps the book could have benefited from more insight from psychologists – but the question has profound implications, and is certainly worth asking.
The book is also a fun read, with plenty of meat to chew on. Lewis has a refreshing willingness to call out the pretentious and the pseudo-scientific, and ridicules the embarrassing attempts by people like Francis Galton, a 19th-century polymath and eugenics pioneer, to tie genius to genetics. (Commenting on Galton’s insistence that he could see no reason why a man born with great intellect could ever be “repressed”, she inserts “a small reminder that this was a man who had seen human beings bought and sold at a market.”)
She is also sharp and witty. While exploring why Elon Musk is fervently discussed as a genius but Tim Berners-Lee, whose achievements are even more considerable, being credited with the invention of the world wide web, is not, she points out: “Elon Musk has more than a dozen children, with names like X A E A-Xii and Exa Dark Sideræl. Tim Berners-Lee’s children are called Alice and Ben.”
By the time we finish The Genius Myth, Lewis has made her case compellingly: that calling people geniuses gives them licence to misbehave; that we vastly overestimate talent and underestimate environment when evaluating people’s success; and that the myth of the genius persists because it makes for a far more compelling story than the alternative. One of the most fascinating paragraphs in the book examines why we may want genius to be more about mysterious inspiration than hard work. Perhaps we are so invested in the notion because it lets the rest of us off the hook for not achieving more. “After all, if Cézanne’s genius was to devote decades of his life to a single idea, what’s stopping us from doing the same?”

Sophie Gilbert is a journalist at The Atlantic, a cultural critic and author of Girl on Girl: How Pop Culture Turned a Generation of Women Against Themselves.
In Girl on Girl, you argue that porn became an increasingly prominent cultural force from the 1990s onwards. How did that happen?
In some ways it was just because there was this really unprecedented increase in the number of people watching it. Before VHS people had to go to a movie theatre to watch porn and that was a huge deterrent. Then suddenly you had this technology that allowed them to watch it in their homes. Between the mid-80s and the mid-90s, there was something like a tenfold increase in the number of people renting porn on VHS in the US. And then obviously the internet increased access further.
Because porn is seen as shameful, no one is really talking about it, but it does have a massive influence on popular culture. You see it first in art in the 70s and 80s, then in fashion, then it creeps into music and TV and movies. If you look at the porn movies of the 70s now, people really thought they were making art. The reason why people like [American writer and journalist] Joan Didion were going to watch porn movies in the 70s was because there was this interest in whether or not sex could become an art form.
But as porn became more ubiquitous online, and at the same time mainstream culture became more sexualised, porn had to do something to stand out. It had to persuade people to keep paying for it, which is hard to do when you’ve got sex on TV and in movies, so it became more extreme, more violent – and more degrading, especially to women.
And that had a knock-on effect on broader culture?
You can definitely see culture mimicking porn’s extremity in the 2000s. But porn has also influenced the ways in which people have sex. There are studies that show an increase in the number of women who’ve been choked during sex without consent, and who’ve encountered violent sexual acts like spitting, gagging, hitting. [The depiction of choking in porn is due to be banned in the UK.]
Under the Online Safety Act, platforms hosting pornographic content must now verify that users are over the age of 18. Is this a positive step?
There are people who are a lot more versed on the internet than I am who argue that it will not have any impact. That said, I’m just amazed that it’s taken so long for people to try to have any kind of filtering at all. We have had extreme porn on the internet now for almost 30 years. We have a generation – [the singer] Billie Eilish has talked a lot about this – who grew up seeing extreme pornographic content before they’re of an age where they can make sense of it. There’s no perfect way to manage exposure to porn, but I’m still staggered that people think there’s no point in trying when we can see quite clearly the negative impact that porn is having on sex and sexuality.
To some people, including to some feminists, this is a kind of moral panic – just another step in the long history of attempting to censor sexual content.
I’m not opposed to porn and I say that in Girl on Girl. I’ve been criticised from the left for being “scoldy” about porn and I’ve been criticised from the right for not being scoldy enough. And I think that’s because I’m sort of pragmatic. People have always sought out imagery of sex using new technologies. The minute the printing press was introduced people were using it to make sexual imagery; there are cave paintings of sexual imagery. People love watching sex and I don’t think there’s anything wrong with that.
The problem is that the imagery that has been fed to us for at least the last three decades – and honestly much longer than that – has really catered to a male gaze. It depicts sex as something that is all about pleasing men and that women just have to submit to. There’s a reason why we’ve seen this massive surge of interest in romantic fiction among women. It’s because women are drawn to sexual content too, but they want the kind of content that centres their pleasure, their desire and agency, and sees them as fully human rather than passive sex objects that just have things done to them.
The subscription service OnlyFans hosts pornographic content by full-time sex workers, but also by pop stars, actors and others, who use it as gig work or to subsidise their artistic careers. Is that the end point of the “pornification” of pop culture you’re describing?
I don’t know if it’s an end point; it’s just another form of technology. I do think OnlyFans is really interesting because it’s not driven by mass clicks. There’s an intimacy to the relationship between creators and their fans that in some ways makes space for a much wider sense of what’s desirable. A lot of the OnlyFans celebrities are women over 50, such as actresses Denise Richards and Carmen Electra. There are creators who don’t have the same kind of bodies that traditional porn stars have had. There’s a lot more space for the complexity of what we as human beings are attracted to.
At the same time, there’s a generation of men who are being taught to think of women as people who are sycophantic to them. You can’t see the person as your equal, because they’re catering to you for money.
You’re interested in how these dynamics filter into the wider world. What’s your take on the cover of Sabrina Carpenter’s latest album Man’s Best Friend? It sparked controversy by showing the singer-songwriter kneeling down at the feet of a man who is pulling her by the hair.
What’s interesting to me is that if that album had come out in the 2000s, we wouldn’t have been having the same conversations that are being had now. I saw women debating that on Instagram with enormous wisdom and insight and complexity, and a real openness to sexuality from women in a way that was not shaming, but was also aware that stars don’t exist in a vacuum, that the ways in which they want to portray themselves always have an impact on the rest of us. I think women and girls today are so much better educated about these issues. They have better language to talk about them and a much better understanding of the dynamics of sex and power.
You describe a kind of cultural correction that started in the 2010s, with more complex representations of women on screen. Are you positive about the future?
Yeah, it’s been really incredible to see. In the Golden Globes in 2025 there were so many more women behind the camera, women directors, there were actresses in their 50, 60s, 70s doing some of the most interesting work of their lives, in stories about the transition into motherhood or beauty culture in Hollywood. None of this was happening in the 2000s. So there’s a willingness in mainstream culture now to reckon with women and their interiority and their lives and their stories that is incredibly heartening to me.
At the same time, most people now go to see one movie a year. For most people now, culture is the content on their phones. And so in some ways, I think that’s the next frontier. There is just a wild west of different platforms and technologies that people my age [Gilbert is 42] have not got any clue what to do with. The mainstream culture, the culture that I still write about – the books and the television and the art – has changed for the better in so many ways and there’s such incredible storytelling out there. But I do think we’re also facing a new world of social media and phone use and we have to confront the question of what to do about it.

I am staging a one-off performance of the World’s Most Boring Card Trick at Magic Fest in Edinburgh on the 27th December. Tickets here. Anyway, I digress. I have long been fascinated by the psychology of humour and once carried out a project called LaughLab. Billed as the search for the world’s funniest joke, over 350,000 people submitted their top gags to our website and rated the jokes sent in by others. We ended up with around 40,000 jokes and you can read the winning entry here (there is also a free download of 1000 jokes from the project).
It was a great project and is still quoted by media around the world. I ended up dressing as a giant chicken, interviewing a clown on Freud’s couch, and brain scanning someone listening to jokes.
A few years ago, I came up with a theory about Christmas cracker jokes. They tend to be short and not very funny, and it occurred to me that this is a brilliant idea. Why? Because if the joke’s good but you don’t get a laugh, then it’s your problem. However, if the joke’s bad and you don’t get a laugh, then you can blame your material! So, cracker jokes don’t embarrass anyone. Not only that, but the resulting groan binds people together. I love it when the psychology of everyday life turns out to be more complex and interesting than it first appears! As comedian and musician Victor Borge once said, humour is often the shortest distance between people.

I recently went through the LaughLab database and pulled out some cracker jokes to make your groan and bond:
– What kind of murderer has fibre? A cereal killer.
– What do you call a fly with no wings? A walk.
– What lies on the bottom of the ocean and shakes? A nervous wreck.
– Two cows are in a field. One cow: “moo”. Other cow: “I was going to say that”
– What did the landlord say as he threw Shakespeare out of his pub? “You’re Bard!”
– Two aerials got married. The ceremony was rubbish but the reception was brilliant.
– What do you call a boomerang that doesn’t come back? A stick.
– A skeleton walks into a pub and orders a pint of beer and a mop.
The BBC have just produced an article about it all and were kind enough to interview me about my theory here.
Does the theory resonate with you? What’s your favourite cracker joke?
Have a good break!
First, a quick announcement – I will be presenting a special, one-off, performance of The World’s Most Boring Card Trick at the Edinburgh MagiFest this year. At a time when everyone is trying to get your attention, this unusual show is designed to be dull. Have you got what it takes to sit through the most tedious show ever and receive a certificate verifying your extraordinary willpower? You can leave anytime, and success is an empty auditorium. I rarely perform this show, and so an excited and delighted to be presenting it at the festival. Details here.
Now for the story. When I was a kid, I was fascinated by a magazine called World of Wonder (WoW). Each week it contained a great mix of history, science, geography and much more, and all the stories were illustrated with wonderful images. I was especially delighted when WoW ran a multi-part series on magicians, featuring some of the biggest names in the business. My favourite story by far was based around the great Danish-American illusionist Dante, and the huge, colourful, double page spread became etched into my mind.

A few years ago, I wrote to the owners of WoW, asking if they had the original artwork from the Dante article. They kindly replied, explaining that the piece had been lost in the mists of time. And that was that.
Then, in July I attended the huge magic convention in Italy called FISM. I was walking past one of the stalls that had magic stuff for sale, and noticed an old Dutch edition of WoW containing the Dante spread. I explained how the piece played a key role in my childhood, and was astonished when the seller reached under his table and pulled out the original artwork! Apparently, he had picked it up in a Parisian flea market many, many, years ago! The chances!

I snapped it up and it now has pride of place on my wall (special thanks to illusion builder Thomas Moore for helping to make it all happen!). My pal Chris Power made some enquirers and thinks that the art was drawn by Eustaquio Segrelles, but any additional information about the illustration is more than welcome.
So there you go – some real magic from a magic convention!
A few months ago, I was invited to present a series of events at FISM — often referred to as the Olympics of Magic. It’s a gathering of over 2,500 magicians from around the world, featuring days of intense magic competitions alongside workshops, lectures, and performances. This year, the event was organised by my friend Walter Rolfo, who kindly asked me to deliver a lecture, interview several well-known performers — including quick-change artist Arturo Brachetti, Luis de Matos, Mac King, and Steven Frayne — and also stage my show Experimental.
It was an incredible week. Magic is a small, strange, and tightly-knit community, and it was a joy to reconnect with people I hadn’t seen in years. One highlight was a great workshop on acting and magic by actor Steve Valentine. Steve and I first crossed paths back in 1983 when we were both competing in The Magic Circle’s Young Magician of the Year. Neither of us won; that honour (quite rightly) went to Richard Cadell—now a regular performer alongside Sooty and Sweep.
My show Experimental is somewhat unusual because there’s no performer. Instead, the audience takes part in a series of illusions and psychological experiments by following prompts on a large screen at the front of the room. Each show is different and shaped entirely by the people in the room. I sit quietly at the back, guiding the experience by choosing the order of the material.
The idea for Experimental came to me years ago, as I was thinking about why magicians perform. It struck me that if a performer genuinely wants to entertain their audience, their words and actions tend to come from a place of generosity. As I like to say, their feet will be pointing in the right direction and so any steps that they take will tend to be positive. But if they come on stage purely to feed their own ego, the audience take second place and the show usually suffers. Removing the performer entirely forced me to design an experience that prioritises the audience from start to finish.
After each performance at FISM, we held a Q&A with the audience. Time and again, I was reminded of something the legendary illusionist David Berglas once told me. One night we were flipping through an old photo album when we came across a picture of him, aged about eight, putting on some kind of show. I asked if it was his first performance. He paused and said, “No. That wasn’t a performance—that was me showing off.”

Curious, I asked him what the difference was. His answer has always stuck in my mind: “Performing is for the good of the audience. Showing off is for the good of the performer.”
I have always thought that there was an interesting life lesson there for everyone, and it was nice to spend many a happy hour chatting about the idea at the amazing and unique event that is FISM.
