Looking for meaningful romantic relationships? Start by diversifying your friendships and forgetting your wishlist

When you’re looking for a relationship, chances are you’ll start off with a wishlist for your ideal partner. Maybe someone who is attractive or wealthy, someone who likes the same movies and the outdoors. Seems like a solid starting point, right? The problem is that in the real world, these wishlists are rarely helpful. And how realistic is the idea that one person can fulfil all our needs in the first place?

In 2017, researchers conducted a large speed-dating study. They wanted to see how well the preferences people indicated for a potential partner predicted who they wanted to see again after the event.

The researchers were left with nothing: people’s wishlists did not predict who they actually liked. Instead, they suggested that the best predictor of whether you like someone is seeing how they make you feel when you interact with them. Do you feel comfortable in their presence? Do they make you laugh?

The scientific evidence suggests that you have to meet people in the flesh if you want to find your match.


Dating today can feel like a mix of endless swipes, red flags and shifting expectations. From decoding mixed signals to balancing independence with intimacy, relationships in your 20s and 30s come with unique challenges. Love IRL is the latest series from The Conversation’s Quarter Life that explores it all.

People used to find their romantic partner by tapping into their social networks – through friends, family, or the people they met in their daily lives. Nowadays, we often look for a romantic partner using online dating platforms, which allow us to access a larger network of potential romantic partners than ever before.

This apparent abundance may encourage a critical comparison with your wishlist and you may spend a lot of time swiping through profiles of potential partners, without initiating meeting them.

Research suggests that doing so can leave you feeling paralysed by an overload of choice and less optimistic about your chances. Research also shows that people tend to have fewer matches as the number of profiles on offer increases.

The researchers of this paradox suggest that you may be wise to put yourself on a dating diet: only looking at a limited number of profiles each day and exploring them with a curious mind. Then, when contact is established and you feel positive about the initial interaction, the real experiment begins.

When you spend a long time interacting online you may construct an idealised version of your potential partner and what you hope they’re like. That leaves you all the more likely to be disappointed when meeting them in person, as it’s easy for them to fall short of your expectations.

A better strategy would be to meet them in the flesh with a curious mind, before becoming overly invested in an online persona that is not a fair representation of what the other person may be like.

Taking it offline

Whether you will go on to have a satisfying relationship in the long run depends more than anything on your relationship expectations and behaviour.

Being kind and attentive to each other’s goals and needs ensures each partner’s happiness and will help weather any challenge, small or large, that couples inevitably face. But here too, technology may disrupt your mindful awareness of others – for example being on your phone in the presence of your partner – posing a risk to enjoying relationships.

Couples today also seem to have historically high expectations for their partner to help them fulfil all their goals and needs. You may want a partner to be a passionate lover, your best friend, your motivational coach and help you achieve personal growth.

In other words, people’s wishlists people carry into relationships too, as we long for a partner to fulfil all our needs.

Demanding all of this from one partner can place too much pressure on the relationships, rather than satisfying your needs. You may be left with a dissatisfying relationship that falls short of your expectations.

In some ways, we may all benefit from adopting lower expectations when looking for a partner and when being with them long term. This may help us appreciate them instead of taking their support and kind acts for granted.

It’s also a good idea to diversify your relationships. Having other important close (and even less close) relationships can help fulfil some needs your partner may not be best suited to meet, such as friends who like the same movies you do or who like to explore the outdoors together.

Research has shown that a greater diversity of relationships benefits happiness, as different relationships can serve different roles in fulfilling your needs, which may take some pressure off “the one” fulfilling all your needs.

Putting some brakes on your expectations for a romantic partner, when looking for a partner and when sharing your life with them, may help you to see more clearly who they are and appreciate what they contribute to your life.

AI can be your wingman when online dating – but should you let it?

Many dating app companies are enthusiastic about incorporating generative AI into their products. Whitney Wolfe Herd, founder of dating app Bumble, wants gen-AI to “help create more healthy and equitable relationships”. In her vision of the near future, people will have AI dating concierges who could “date” other people’s dating concierges for them, to find out which pairings were most compatible.

Dating app Grindr is developing an AI wingman, which it hopes to be up and running by 2027. Match Group, owner of popular dating apps including Tinder, Hinge and OK Cupid, have also expressed keen interest in using gen-AI in their products, believing recent advances in AI technology “have the power to be transformational, making it more seamless and engaging for users to participate in dating apps”. One of the ways they think gen-AI can do this is by enhancing “the authenticity of human connections”.

Use of gen-AI in online dating is not just some futuristic possibility, though. It’s already here.

Want to enhance your photos or present yourself in a different style? There are plenty of online tools for that. Similarly, if you want AI to help “craft the perfect, attention-grabbing bio” for you, it can do that. AI can even help you with making conversation, by analysing your chat history and suggesting ways to reply.

Extra help

It isn’t just dating app companies who are enthusiastic about AI use in dating apps either. A recent survey carried out by Cosmopolitan magazine and Bumble of 5,000 gen-Zers and millennials found that 69% of respondents were excited about “the ways AI could make dating easier and more efficient”.

An even higher proportion (86%) “believe it could help solve pervasive dating fatigue”. A surprising 86% of men and 77% of the women surveyed would share their message history with AI to help guide their dating app conversations.

It’s not hard to see why AI is so appealing for dating app users and providers. Dating apps seem to be losing their novelty: many users are reportedly abandoning them due to so-called “dating app fatigue” – feeling bored and burnt out with dating apps.

Apps and users might be hopeful that gen-AI can make dating apps fun again, or if not fun, then at least that it will make them actually lead to dates. Some AI dating companions claim to get you ten times more dates and better dates at that. Given that men tend to get fewer matches on dating apps than women, it’s also not surprising that we’re seeing more enthusiasm from men than women about the possibilities AI could bring.

Talk of gen-AI in connection to online dating gives rise to many ethical concerns. We at the Ethical Dating Online Network, an international network of over 30 multi-disciplinary academics interested in how online dating could be more ethical, think that dating app companies need to convincingly answer these worries before rushing new products to market. Here are a few standout issues.

Pitfalls of AI dating

Technology companies correctly identify some contemporary social issues, such as loneliness, anxiety at social interactions, and concerns about dating culture, as hindering people’s dating lives.

But turning to more technology to solve these issues puts us at risk of losing the skills we need to make close relationships work. The more we can reach for gen-AI to guide our interactions, the less we might be tempted to practise on our own, or to take accountability for what we communicate. After all, an AI “wingman” is of little use when meeting in person.

Also, AI tools risk entrenching much of dating culture that people find stressful. Norms around “banter”, attractiveness or flirting can make the search for intimacy seem like a competitive battleground. The way AI works – learning from existing conversations – means that it will reproduce these less desirable aspects.

Instead of embracing those norms and ideals, and trying to equip everyone with the tools to seemingly meet impossibly high standards, dating app companies could do more to “de-escalate” dating culture: make it calmer, more ordinary and help people be vulnerable. For example, they could rethink how they charge for their products, encourage a culture of honesty, and look at alternatives to the “swiping” interfaces.

The possibility of misrepresentation is another concern. People have always massaged the truth when it comes to dating, and the internet has made this easier. But the more we are encouraged to use AI tools, and as they are embedded in dating apps, bad actors can more simply take advantage of the vulnerable.

An AI-generated photo, or conversation, can lead to exchanges of bank details, grooming and sexual exploitation.

Stopping short of fraud, however, is the looming intimate authenticity crisis. Online dating awash with AI generated material risks becoming a murky experience. A sincere user might struggle to identify like-minded matches on apps where use of AI is common.

This interpretive burden is annoying for anyone, but it will exacerbate the existing frustrations women, more so than men, experience on dating apps as they navigate spaces full of with timewasting, abuse, harassment and unwanted sexualisation.

Indeed, women might worry that AI will turbo-charge the ability of some men to prove a nuisance online. Bots, automation, conversation-generating tools, can help some men to lay claim to the attention of many women simultaneously.

AI tools may seem like harmless fun, or a useful timesaver. Some people may even wholeheartedly accept that AI generated content is not “authentic” and love it anyway.

Without clear guardrails in place, however, and more effort by app companies to provide informed choices based on transparency about how their apps work, any potential benefits of AI will be obscured by the negative impact it has to intimacy online.

Alpha males are surprisingly rare among primates – new research

Source: The Conversation – UK – By Louise Gentle, Principal Lecturer in Wildlife Conservation, Nottingham Trent University

Female lemurs are often dominant. Miroslav Halama/Shutterstock

Is it true that male animals are dominant over females? Previous studies have often found male-biased power in primates and other mammals.

A new study, investigating physical encounters between members of the same species in 121 primates (around a quarter of all primate species) found that half of all aggressive contests were between males and females. But males won these contests in only 17% of primate populations, with females dominating in 13% – making it almost as likely for females to dominate males.

The remaining 70% of primate populations showed no clear-cut dominance of one sex over the other. This study may have shown different results to previous research because it assessed individual contests rather than categorising species based on their social structure and physical attributes.

The new study found male dominance, where males have a greater ability to influence the behaviour of the opposite sex, to be prevalent in primate species where the males are much larger than the females. This enables males to gain dominance through physical force or coercion. It was also widespread in species where males have weapons and mate with lots of females.

This is typical of African and Asian monkeys and the great apes, such as gorillas. Weighing in at around 200kg, a silverback male can be twice the size of the females within his troop. Male gorillas also have large canine teeth that can seriously injure or even kill other gorillas.

Male dominance often twins with weapons throughout the animal kingdom, – horns, antlers, claws or tusks. The largest antlers ever known were those of the now extinct Irish elk, spanning lengths up to 3.5m.

Female dominance

Female power was seen in primate species that had a scarcity of females, one exclusive sexual partner, similar sized males and females but did not have bodily weapons, according to the new study. These are all factors that give females more choice over who to mate with.

Female dominance was also seen in species where fighting with a male was less risky for the dependent offspring of females. For example, some primates “park” their young on their own in nests while foraging, rather than carrying them around. If a mother is holding her baby when she’s attacked, she may submit to protect her young.

Finally, matriarchal societies were common in species that live primarily in trees, which makes it easier to flee an attacker.

Female-dominated species were more likely in lorises, galagos and lemurs. So, contrary to the film Madagascar where King Julien is the king of the lemurs, females are, in fact, in charge. In the ring-tailed lemurs, females control access to food and mates, and maintain the dominance hierarchy where males are often at the bottom.

This is also true of bonobos, the closest relatives of humans. Although male bonobos are larger, females form coalitions to overcome the physical power of the males and force them into submission. This show of solidarity has also been shown in humans.

Think of how the suffragettes campaigned for women’s rights to vote in the UK. Or more recently, how women demanded new safety measures after Sarah Everard was murdered by Metropolitan Police officer Wayne Couzens in 2021.

Although female dominance has been documented less often in the wider animal kingdom, there are some examples that defy expectations. Spotted hyenas have a matriarchal society where females dominate the clans. They even have a pseudo-penis that they erect to indicate submission to more dominant individuals.

Naked mole rats have a queen that gives birth to all of the young while her offspring find food and defend the nest. The males are subordinate to the queen, but so too are the other females. In fact, the queen bullies the other members of her colony so much that the females are all rendered sterile through stress.

But what about the 70% of primate species that were found to show no dominant sex bias in the new study? These were largely the South American monkeys such as marmosets, tamarins and capuchins, that are generally small, live in trees, are social and omnivorous.

They also tended to have a prehensile tail that helps them grasp things. The ecology of these species fall in the middle of the male and female dominated species, with size difference and weapons being neither extreme nor absent, mating systems being neither polygamous nor monogamous, and the frequency of females being nether abundant nor rare.

The absence of a definitive sex-bias in dominance found in the majority of primate species may be a result of the rarity of contests between males and females, or because males and females were both equally likely to win. Nevertheless, dominance varied within species. For example the percentage of intersexual contests won by female patas monkeys ranged from 0% to 61%, depending on the population studied.

What does this mean for humans?

Human traits are not skewed towards those of male-dominated societies in other primates. We may not live in trees but males do not have natural weapons. Males are not always bigger than females, females do not tend to outnumber males and our sexual habits are varied.

Humans are actually more aligned to the 70% of species that show no clear distinction in sex biases, where species of either sex can become dominant. Let’s see which way evolution takes us.

Small penises are still the butt of the joke in film and TV

Source: The Conversation – UK – By Neil Cocks, Associate Professor in the Department of English Literature, University of Reading

Gen V (2023-present), the recent iteration of the wildly successful superhero satire The Boys (2019), thrives on scenes of bodily outrage. One such episode concerns a young woman who is able to shrink – an ability triggered by self-induced vomiting.

Her boyfriend persuades her to use her powers during sex and we see her touching his penis, which is now taller than she is. We also understand why the boyfriend is so insistent about her transformation: relatively speaking, he has a small penis.

In Companion (2025), a film about a young man who has an abusive sexual relationship with a self-conscious robot, a small penis is also mocked. When the robot gains autonomy, and has an intelligence boost, she confronts and shames the abusive man, claiming that he is motivated in his violent and controlling behaviour by “a below average-sized penis”.

What interests me about these works, as a researcher of sexuality and film, is that they are otherwise committed to questioning reductive ideas about the body. Yes, in the universe of The Boys there is undoubted glee at all the exploding heads and superpowered, murderous buttocks, but the keynote is pathos.

The girl who changes her shape through vomiting is arguably representing bulimic experience and there are characters whose superpowers can be understood to negotiate, for example, self-harm and dysmorphia. But when it comes to a man with a small penis, it’s a different story. His body is understood to directly influence both his actions and sense of morality.

Likewise, in Companion, which is in so many senses a meditation on the fraught relationship between mind and body, the small penis of the young man is understood to be the obvious source of his repressive actions.

In both cases, the audience is expected to laugh at the abuser because of his small penis. The small penis is framed as both a signifier and cause of abusiveness.

‘We are still so medieval about penis size’

It could be argued that in Companion and Gen V, the small penis itself is not what is being mocked. The men involved in both are young, white and heterosexual. The idea is, perhaps, that mocking those with small penises is acceptable, because in this the creators are really questioning white, heterosexual and male power structures, and that the inadequacy of that power, its mythic nature, is exposed.

One difficulty in this is that as only power held by men with small penises is mocked, the power of the well endowed, regardless of racial or sexual identity, is naturalised.

Equally, those people of colour or queer people who have small penises might implicitly be included in the mockery, with the implication that they are somehow the beneficiaries of power structures, misuse this power, and have obvious, biologically rooted motivations in so doing.

The trailer for Gen V.

Gen V qualifies the laughter – the girl , talking later to a friend, makes clear that there is nothing wrong in having a small penis, just “don’t be a dick about it”. But the only small-penised character we see is, of course, being “a dick”.

There have been a number of television shows that focus on penis size, but each explores the pathos of having a large penis: Hung (2009), The Hard Times of RJ Berger (2010), Sex Education (2019). Imagine an equivalent concerning a character with a small – or even simply not large – penis.

As journalist Caitlin Moran wrote in a 2023 Guardian article introducing her book, What About Men:

We are still so medieval about penis size that we see male genitalia as being inimical to a man’s soul. Remember when Stormy Daniels told the world that Donald Trump’s penis was ‘smaller than average – a dick like the mushroom character in Mario Kart’. And we were all like: ‘Yes, it makes sense the horrible man has a small, weird mushroom penis.’ The whole world joined in on that one.

Let us instead question the relationship between biology and destiny. And let this action be taken not to frame heterosexual white men as a disadvantaged group, but for the good of us all. Our bodies are ours to negotiate, with ourselves, and with our significant others, as well as those others that find in them indifference, or more troubling affects.

As Gen V and Companion suggest, in recent science fiction stories that otherwise reimagine the body, the small penis can only be imagined as shameful. It is taken to be an obvious motivation for abusive behaviour. Such an understanding helps no one. As the science fiction genre is especially well placed to question common-sense ideas about the human and its form, it would be a good place to begin.

MethaneSat: The climate spy satellite that went quiet

Source: The Conversation – UK – By Vincent Gauci, Professorial Fellow, School of Geography, Earth and Environmental Sciences, University of Birmingham

Satellites circling the Earth have many different functions, including navigation, communications and Earth observation. About 8%-10% of all active satellites are military or “dual use” serving intelligence or reconnaissance functions as spy satellites.

But it was a climate satellite serving as both spy and “name and shame” police officer in the sky that recently caught the world’s attention when it went quiet.

MethaneSat was developed to spot emission hot spots or plumes of invisible methane pollution from space. Built by the US non-profit, the Environmental Defense Fund with Nasa’s support, it tracked methane leaks from oil and gas sites, farms and landfills across the globe.

These are among the biggest human-caused emission sources. But methane emissions are traditionally hard to spot because they come from so many relatively small point sources or plumes.

This specialist observation satellite was developed and deployed because methane acts differently to other greenhouse gas emissions. Methane is a powerful greenhouse gas that, over 20 years, is more than 80 times more powerful a greenhouse gas than carbon dioxide.

Since 1750, additional human-caused methane emissions have contributed directly and indirectly, to around 60% of the global warming of carbon dioxide over that time.

Methane also has a short lifetime. Where carbon dioxide stays in the atmosphere for in excess of 100 years, relying on plant uptake for its removal from the atmosphere and conversion into other carbon forms, methane is broken down in the atmosphere by molecules known as hydroxyl radicals. These are nicknamed “the atmosphere’s detergent”, because they effectively remove methane from the atmosphere in less than ten years.

This combination of short lifetime and high global warming potential (a measure of the climate strength of the gas relative to carbon dioxide) makes methane both a problem and an ideal target for reduction. In fact, growth in atmospheric methane is occurring at such a rate that it is placing us dangerously off track from meeting our Paris agreement obligations to stay within 1.5°C of climate warming by 2050 and 2°C by 2100.

Eyes in the sky

But how can we achieve these reductions and what was the role of MethaneSat in seeking to meet this objective?

There are two ways atmospheric methane concentrations can be reduced. A recent and more challenging proposition is that methane is actively removed from the atmosphere.

This is difficult because it relies on technological advances that are at their earliest stages (although growing more trees can go some way to achieving this). Another more realistic approach is to reduce emissions and then to let atmospheric chemistry do the work of removing excess methane in the atmosphere.

The global methane pledge was announced in 2021 at the UN climate summit, Cop26, in Glasgow. This aimed to reduce human-caused methane emissions by 30% on 2020 levels by 2030. More than 150 countries have now signed up to this pledge. If successful, it could reduce warming by up to 0.2°C by 2050. That’s why MethaneSat was so useful.

MethaneSat is fitted with a hyperspectral sensor – which can record sunlight reflected off Earth in hundreds of narrow colour bands across the spectrum, far beyond what our eyes can see. It’s capable of picking up concentrations of methane in air at minute quantities.

This sensor allowed the satellite to spot individual plumes of methane, so it had a crucial role in identifying those problem areas. Given that these are dispersed but also individual point sources, it was invaluable in intervening in the leaks, permitting identification of those responsible so they could be held to account and so address the problem.

No one instrument can cover what MethaneSat could do with freely available data. It had high precision, high spatial resolution and, critically, global coverage and it was particularly useful at identifying plumes in nations that don’t have the resources for the sort of regional surveys using aircraft mounted systems that can fill the gap in developed regions.

Now that MethaneSat is no longer operational, there are some other tools to identify small anthropogenic emissions sources, but they tend to be regionally focused like the aircraft measurements mentioned.

Other satellites gather similar data but that data sits behind commercial paywalls, whereas MethaneSat data was freely available. Collectively, these drawbacks mean that it’s just going to be that much harder to spot the emissions MethaneSat was so good at tracking.

Zonal pricing is dead – here’s how the UK should change its electricity system instead

Source: The Conversation – UK – By Cassandra Etter-Wenzel, DPhil Candidate in Energy Policy, University of Oxford

Marcin Rogozinski/Shutterstock

The UK government has decided against setting different prices for electricity based on the locations of consumers.

Zonal pricing would have categorised Britain into distinct zones, each with wholesale electricity prices that reflect how much power is generated locally, and how much demand there is for it. It would have raised prices in areas with lots of demand but low generation, like London, and lowered them where supply outstrips demand, such as in the turbine-rich Scottish Highlands.

This might have caused an immediate increase in the energy bills of already vulnerable households in some high-demand, low-generation areas, such as Tower Hamlets in London and Blackpool in north-west England.

But the idea was to encourage the construction of renewable energy to meet high demand in higher-priced zones, and prompt big electricity consumers to move to where electricity is cheaper. It was also intended to ease the need for new infrastructure to transmit electricity over long distances, like pylons. Australia, Norway and several EU nations already use this method.

The ultimate goal of zonal pricing was to make the price of electricity more accurately reflect generation and transmission costs. However, one thing has significantly inflated electricity prices in recent years, which this pricing method wouldn’t have addressed on its own: gas.

Gas is expensive, even more so since Russia’s invasion of Ukraine. Britain’s electricity system operator brings power plants onto the system to meet demand in order of the lowest to highest marginal costs.

The point at which supply meets demand forms the wholesale price of electricity. Renewable sources, like wind and solar, have zero or very low marginal costs. But most of the time the wholesale price is set by gas plants, because they can readily fill a gap in supply but have high and erratic marginal costs (largely tied to what they pay for fuel).

We need another, cheaper technology to set the wholesale price of electricity. Batteries, which can store electricity over several hours, and options capable of storing energy for longer, such as compressed air and low-carbon hydrogen, could be just the thing.

The idea is simple: batteries can be charged at times when there is a lot of surplus electricity generation (on a bright, windy day, for example) and discharge it at times of peak demand (or when the sun doesn’t shine and the wind doesn’t blow). This would entail grid operators (and ultimately, consumers) not having to pay gas plants to fire up when renewable generation cannot meet the shortfall.

Unfortunately, batteries comprised just 6% of Britain’s total electricity capacity in 2024. Investment in energy storage has lagged behind what the government forecasts is necessary to meet its 2030 clean power goals, but it is at least increasing.

Research shows that the more money that is invested in batteries, the more associated costs come down. If used instead of gas to stabilise the grid, energy storage could significantly lower the wholesale cost of the UK’s energy over time, and with the right balance of policies, household bills too. This would require subsidies to cover some of the cost of making and installing batteries, and planning mandates to build new renewables alongside new batteries.

Affordable and fair

The government could also try alternatives to zonal pricing. Wholesale electricity prices could reflect the “strike” price in renewable energy contracts. This is the price at which developers have agreed to build clean electricity generation projects, like wind farms. This would mean that gas no longer sets the wholesale price, but stable, predictable prices agreed years in advance, which would help to regulate the retail costs consumers pay.

These types of reforms can help set efficient energy prices, which the government usually talks about as the price needed to encourage investment in new energy technologies. But just because prices are efficient, it doesn’t mean they’re fair. Some households struggle to afford their energy bills even when markets are working efficiently. So, when prices change to encourage cleaner energy, it can hit them harder.

The government should implement new policies and expand eligibility for existing measures to take the burden off energy-poor households. These include social tariffs, which offer discounted rates to vulnerable consumers, and discounts for blocks of electricity use when renewables are generating a lot of it.

Transition funds could help poorer households meet bills, while schemes to encourage home insulation and other improvements could see more homes with rooftop solar panels and battery storage.

This support, combined with increasing investment in energy storage and renewables, will lower the wholesale price of electricity over time – and make energy more affordable (and fair) for everyone.

Measles isn’t just dangerous – it may erase your immune system

Source: The Conversation – UK – By Antony Black, Lecturer, Life Sciences, University of Westminster

Blindness, pneumonia, severe diarrhoea and even death – measles virus infections, especially in children, can have devastating consequences. Fortunately, we have a safe and effective defence. Measles vaccines are estimated to have averted more than 60 million deaths between 2000 and 2023.

Yet despite this success, measles cases are rising sharply in the UK and around the world. This global surge is the result of several factors, from vaccine hesitancy to missed immunisation campaigns, leaving many children unprotected and vulnerable.

But there’s more at stake than just measles itself. Emerging research suggests that the measles vaccination may offer surprising additional health benefits. Children who receive the vaccine have been shown to have a significantly lower risk of infections from diseases unrelated to measles.

One explanation for this broader benefit is the idea of “measles amnesia.” This refers to the ability of the measles virus to erase parts of the body’s immune memory.

Our immune system contains various cells that protect us from infections. Some produce antibodies that neutralise viruses, while others detect and destroy infected cells. Immune memory allows the body to “remember” past infections and mount faster responses in the future.

However, measles infection may reduce the number and diversity of these memory cells – leaving children vulnerable to a wide range of diseases they had previously developed immunity to. In other words, the virus doesn’t just make children ill in the short term, it may also undo years of immune protection.

In one study, researchers found that between 11% and 73% of antibodies targeting other diseases were lost after a measles infection in unvaccinated children. This immune depletion was not observed in children who had received the vaccine, suggesting that vaccination protects against this damaging effect.

This broad loss of immune protection may explain why measles outbreaks are often followed by spikes in other infectious diseases. Ongoing studies are exploring the impact of measles amnesia in regions such as West Africa, where measles and other infections remain widespread.

A vaccine that does more?

Another theory for the vaccine’s broader benefit is known as the “non-specific effect”. Unlike measles amnesia, which explains how the virus weakens immunity, the non-specific effect suggests that the measles vaccine actively strengthens the immune system against a wide range of pathogens.

Recent research has shown that measles vaccination may enhance the function of certain immune cells, making them more effective at fighting off other diseases. Some scientists believe this effect, rather than protection against amnesia alone, could be the primary reason why vaccinated children have better overall health outcomes.

The measles vaccine is a live attenuated vaccine, which means it uses a weakened version of the virus to stimulate a strong immune response. Live vaccines, including the BCG vaccine for tuberculosis, are known to provide broad immune training effects, which may explain this non-specific protection.

Forgotten the dangers

In the 1960s, before widespread vaccination, measles caused around 2.6 million deaths per year. It’s hard to imagine today, but that’s partly the problem.

As measles became rare, society began to forget how serious it is. We forgot how contagious it is (one infected person can spread the virus to up to 90% of nearby unvaccinated people) and we forgot how effective vaccination is (two doses provide more than 90% long-term protection).

And in some circles, this fading memory has been replaced by something more dangerous: mistrust. Misinformation, vaccine myths, and anti-vaccine rhetoric are spreading, just like the virus itself.

So, whether the additional protection offered by the vaccine is due to prevention of immune amnesia, a non-specific immune boost, or both, the takeaway is the same: Vaccinate children against measles. Because when we protect them from measles, we may also be protecting them from so much more.

California farmers identify a hot new cash crop: Solar power

Imagine that you own a small, 20-acre farm in California’s Central Valley. You and your family have cultivated this land for decades, but drought, increasing costs and decreasing water availability are making each year more difficult.

Now imagine that a solar-electricity developer approaches you and presents three options:

  • You can lease the developer 10 acres of otherwise productive cropland, on which the developer will build an array of solar panels and sell electricity to the local power company.
  • You can select 1 or 2 acres of your land on which to build and operate your own solar array, using some electricity for your farm and selling the rest to the utility.
  • Or you can keep going as you have been, hoping your farm can somehow survive.

Thousands of farmers across the country, including in the Central Valley, are choosing one of the first two options. A 2022 survey by the U.S. Department of Agriculture found that roughly 117,000 U.S. farm operations have some type of solar device. Our own work has identified over 6,500 solar arrays currently located on U.S. farmland.

Our study of nearly 1,000 solar arrays built on 10,000 acres of the Central Valley over the past two decades found that solar power and farming are complementing each other in farmers’ business operations. As a result, farmers are making and saving more money while using less water – helping them keep their land and livelihood.

A hotter, drier and more built-up future

Perhaps nowhere in the U.S. is farmland more valuable or more productive than California’s Central Valley. The region grows a vast array of crops, including nearly all of the nation’s production of almonds, olives and sweet rice. Using less than 1% of all farmland in the country, the Central Valley supplies a quarter of the nation’s food, including 40% of its fruits, nuts and other fresh foods.

The food, fuel and fiber that these farms produce are a bedrock of the nation’s economy, food system and way of life.

But decades of intense cultivation, urban development and climate change are squeezing farmers. Water is limited, and getting more so: A state law passed in 2014 requires farmers to further reduce their water usage by the mid-2040s.

The trade-offs of installing solar on agricultural land

When the solar arrays we studied were installed, California state solar energy policy and incentives gave farm landowners new ways to diversify their income by either leasing their land for solar arrays or building their own.

There was an obvious trade-off: Turning land used for crops to land used for solar usually means losing agricultural production. We estimated that over the 25-year life of the solar arrays, this land would have produced enough food to feed 86,000 people a year, assuming they eat 2,000 calories a day.

There was an obvious benefit, too, of clean energy: These arrays produced enough renewable electricity to power 470,000 U.S. households every year.

But the result we were hoping to identify and measure was the economic effect of shifting that land from agricultural farming to solar farming. We found that farmers who installed solar were dramatically better off than those who did not.

They were better off in two ways, the first being financially. All the farmers, whether they owned their own arrays or leased their land to others, saved money on seeds, fertilizer and other costs associated with growing and harvesting crops. They also earned money from leasing the land, offsetting farm energy bills, and selling their excess electricity.

Farmers who owned their own arrays had to pay for the panels, equipment and installation, and maintenance. But even after covering those costs, their savings and earnings added up to US$50,000 per acre of profits every year, 25 times the amount they would have earned by planting that acre.

Farmers who leased their land made much less money but still avoided costs for irrigation water and operations on that part of their farm, gaining $1,100 per acre per year – with no up-front costs.

The farmers also conserved water, which in turn supported compliance with the state’s Sustainable Groundwater Management Act water use reduction requirements. Most of the solar arrays were installed on land that had previously been irrigated. We calculated that turning off irrigation on this land saved enough water every year to supply about 27 million people with drinking water or irrigate 7,500 acres of orchards. Following solar array installation, some farmers also fallowed surrounding land, perhaps enabled by the new stable income stream, which further reduced water use.

Changes to food and energy production

Farmers in the Central Valley and elsewhere are now cultivating both food and energy. This shift can offer long-term security for farmland owners, particularly for those who install and run their own arrays.

Recent estimates suggest that converting between 1.1% and 2.4% of the country’s farmland to solar arrays would, along with other clean energy sources, generate enough electricity to eliminate the nation’s need for fossil fuel power plants.

Though many crops are part of a global market that can adjust to changes in supply, losing this farmland could affect the availability of some crops. Fortunately, farmers and landowners are finding new ways to protect farmland and food security while supporting clean energy.

One such approach is agrivoltaics, where farmers install solar designed for grazing livestock or growing crops beneath the panels. Solar can also be sited on less productive farmland or on farmland that is used for biofuels rather than food production.

Even in these areas, arrays can be designed and managed to benefit local agriculture and natural ecosystems. With thoughtful design, siting and management, solar can give back to the land and the ecosystems it touches.

Farms are much more than the land they occupy and the goods they produce. Farms are run by people with families, whose well-being depends on essential and variable resources such as water, fertilizer, fuel, electricity and crop sales. Farmers often borrow money during the planting season in hopes of making enough at harvest time to pay off the debt and keep a little profit.

Installing solar on their land can give farmers a diversified income, help them save water, and reduce the risk of bad years. That can make solar an asset to farming, not a threat to the food supply.

Angels, witches, crystals and black cats: How supernatural beliefs vary across different groups in the US

Younger Americans are more likely to express belief in witchcraft and luck, as our new research shows.

As sociologists who research the social dynamics of religion in the United States, we conducted a nationally representative survey in 2021. Our survey posed dozens of questions to 2,000 Americans over the age of 18 on a wide range of beliefs in supernatural phenomena – everything from belief in the devil to belief in the magical power of crystals.

Our statistical analyses found that supernatural beliefs in the United States tend to group into four types.

The first represents what many consider “traditional religious beliefs.” These include beliefs in God, the existence of angels and demons, and belief in the soul and its journey beyond this lifetime.

A second represents belief in “spiritual and mental forces,” some of which are associated with either paranormal or new age beliefs. These include communicating with the dead, predicting the future, or believing that one’s soul can travel through space or time.

A third group represents belief in “witches and witchcraft.” This was measured on our survey with questions about the existence of “black magic” and whether it was “possible to cast spells on people.”

The fourth and final group represents beliefs in supernatural forces that shape “luck” – for instance, that “black cats bring bad luck.”

Our analysis finds that higher education and higher income are associated with lower levels of all four types of supernatural belief. Those with a bachelor’s degree or higher, for instance, score below average on all four types of belief, while those with less education score higher than average on all four.

Looking at race and ethnicity, we found that Latino or Hispanic individuals were more likely than white individuals to express belief in the “witches and witchcraft” form of supernatural belief. About 50% of Latino or Hispanic individuals in our survey, for example, strongly agreed that “witches exist.” This compares with about 37% of white individuals.

Comparing gender differences, we find that women are more likely than men to believe in the “spiritual and mental forces” forms of supernatural belief. For instance, about 31% of women in our survey agreed that “it is possible to communicate with the dead” compared with about 22% of men.

Why it matters

Our research addresses two key questions: first, whether people who hold one type of supernatural belief are also more likely to hold other types of supernatural beliefs; and second, how do different types of supernatural belief vary across key demographic groups, such as across educational levels, racial and ethnic groups, and gender?

Answering these questions can be surprisingly difficult. Most scientific surveys of the U.S. public include, at best, only one or two questions about religious beliefs; rarely do they include questions about other types of supernatural beliefs, such as belief in paranormal or superstitious forces. This could lead to an incomplete understanding of how supernatural beliefs and practices are changing in the United States.

An increasing number of Americans are leaving organized religion. However, it is not clear that supernatural beliefs have or will follow the same trajectory – especially beliefs that are not explicitly connected to those religious identities. For example, someone can identify as nonreligious but believe that the crystal they wear will provide them with supernatural benefits.

Moreover, recognizing that supernatural beliefs can include more than traditionally religious supernatural beliefs may be vital for better understanding other social issues. Research has found, for example, that belief in paranormal phenomena is associated with lower trust in science and medicine.

What’s next

Our survey provides some insight into the nature and patterns of supernatural belief in the U.S. at one point in time, but it does not tell us how such beliefs are changing over time.

We would like to see future surveys – both ours or from other social scientists – that ask more diverse questions about belief in supernatural beings and forces that will allow for an assessment of such changes.

The Research Brief is a short take on interesting academic work.

University students feel ‘anxious, confused and distrustful’ about AI in the classroom and among their peers

The advent of generative AI has elicited waves of frustration and worry across academia for all the reasons one might expect: Early studies are showing that artificial intelligence tools can dilute critical thinking and undermine problem-solving skills. And there are many reports that students are using chatbots to cheat on assignments.

But how do students feel about AI? And how is it affecting their relationships with peers, instructors and their coursework?

I am part of a group of University of Pittsburgh researchers with a shared interest in AI and undergraduate education. While there is a growing body of research exploring how generative AI is affecting higher education, there is one group that we worry is underrepresented in this literature, yet perhaps uniquely qualified to talk about the issue: our students.

Our team ran a series of focus groups with 95 students across our campuses in the spring of 2025 and found that whether students and faculty are actively using AI or not, it is having significant interpersonal, emotional effects on learning and trust in the classroom. While AI products such as ChatGPT, Gemini or Claude are, of course, affecting how students learn, their emergence is also changing their relationships with their professors and with one another.

‘It’s not going to judge you’

Most of our focus group participants had used AI in the academic setting – when faced with a time crunch, when they perceive something to be “busy work,” or when they are “stuck” and worry that they can’t complete a task on their own. We found that most students don’t start a project using AI, but many are willing to turn to it at some point.

Many students described positive experiences using AI to help them study or answer questions, or give them feedback on papers. Some even described using AI instead of a professor, tutor or teaching assistant. Others found a chatbot less intimidating than attending office hours where professors might be “demeaning.” In the words of one interviewee: “With ChatGPT you can ask as many questions as you want and it’s not going to judge you.”

But by using it, you may be judged. While some were excited about using AI, many students voiced mild feelings of guilt or shame about their AI use due to environmental or ethical concerns, or just coming across as lazy. Some even expressed a feeling of helplessness, or a sense of inevitability regarding AI in their futures.

Anxiety, distrust and avoidance

While many students expressed a sense that faculty members are, as one participant put it, “very anti-ChatGPT,” they also lamented the fact that the rules around acceptable AI use were not sufficiently clear. As one urban planning major put it: “I feel uncertain of what the expectations are,” with her peer chiming in, “We’re not on the same page with students and teachers or even individually. No one really is.”

Students also described feelings of distrust and frustration toward peers they saw as overly reliant on AI. Some talked about asking classmates for help, only to find that they “just used ChatGPT” and hadn’t learned the material. Others pointed to group projects, where AI use was described as “a giant red flag” that made them “think less” of their peers.

These experiences feel unfair and uncomfortable for students. They can report their classmates for academic integrity violations – and enter yet another zone in which distrust mounts – or they can try to work with them, sometimes with resentment. “It ends up being more work for me,” a political science major said, “because it’s not only me doing my work by myself, it’s me double checking yours.”

Distrust was a marker that we observed of both student-to-teacher relationships and student-to-student relationships. Learners shared fears of being left behind if other students in their classes used chatbots to get better grades. This resulted in emotional distance and wariness among students. Indeed, our findings reflect other reports that indicate the mere possibility that a student might have used a generative AI tool is now undercutting trust across the classroom. Students are as anxious about baseless accusations of AI use as they are about being caught using it.

Students described feeling anxious, confused and distrustful, and sometimes even avoiding peers or learning interactions. As educators, this worries us. We know that academic engagement – a key marker of student success – comes not only from studying the course material, but also from positive engagement with classmates and instructors alike.

AI is affecting relationships

Indeed, research has shown that faculty-student relationships are an important indicator of student success. Peer-to-peer relationships are essential too. If students are sidestepping important mentoring relationships with professors or meaningful learning experiences with peers due to discomfort over ambiguous or shifting norms around the use of AI technology, institutions of higher education could imagine alternative pathways for connection. Residential campuses could double down on in-person courses and connections; faculty could be incentivized to encourage students to visit during office hours. Faculty-led research, mentoring and campus events where faculty and students mix in an informal fashion could also make a difference.

We hope our research can also flip the script and disrupt tropes about students who use AI as “cheaters.” Instead, it tells a more complex story of students being thrust into a reality they didn’t ask for, with few clear guidelines and little control.

As generative AI continues to pervade everyday life, and institutions of higher education continue to search for solutions, our focus groups reflect the importance of listening to students and considering novel ways to help students feel more comfortable connecting with peers and faculty. Understanding these evolving interpersonal dynamics matters because how we relate to technology is increasingly affecting how we relate to one another. Given our experiences in dialogue with them, it is clear that students are more than ready to talk about this issue and its impact on their futures.
