Grandparents play a pivotal role in family life. They are often a vital part of the childcare puzzle, stepping in to look after their grandchildren while parents are at work or busy. And there’s a lot of grandparent care taking place.

In England, around half of all grandparents provide care for their grandchildren when the parents are not around. And the percentage of grandparents providing care is even higher when they have grandchildren aged 16 and under, who are more likely to require supervision, care, and support from an adult when the parents are busy at work or unavailable. In this case, 66% of grandparents help out.

I used data from the English Longitudinal Study of Ageing, to analyse the caring roles of over 5,000 grandparents. I used data collected in 2016-17 to assess how often grandparents looked after their grandchildren, the activities they did with them, and why they helped out. I also discovered that there are clear gender and socioeconomic patterns. Further analysis of data from 2018-19 showed that providing care as a grandparent can affect wellbeing.

I found that in England, among grandparents who looked after grandchildren, 45% of grandparents spent at least one day a week looking after their young grandchildren. They did so consistently throughout the year, with 8% doing so almost daily. Approximately one in three grandparents provided care to their grandchildren during school holidays.

Around 25% of grandparents who looked after their grandchildren were still working. Most grandparents reported having overall good physical health.

And most grandparents who cared for their grandchildren also lived relatively close to them – less than half an hour away from their closest grandchild – and had at least one grandchild aged under six years old.

Most of the grandparents in the study who cared for grandchildren – 80% – mentioned that they played or took part in leisure activities with their grandchildren. Around half said that they frequently cooked for them and helped with picking them up and dropping them off from schools and nurseries. And although it was less common, grandparents also helped with homework and taking care of their grandchildren when they were not feeling well.

About three grandparents in four (76%) said that their motivation for helping out was to give their grandchildren’s parents some time out from childcare responsibilities. A similar percentage – 70% – said they wanted to provide some economic support, either by offering financial assistance or by allowing parents to go to work.

Just over half of grandparents (52%) said that being able to provide emotional support was what drove their motivation to provide grandchild care: they wanted to feel engaged with young people and help their grandchildren develop. But 17% say that they felt obliged to help out, and found it difficult to refuse.

The grandmother’s role

But while we tend to talk about “grandparents” as a group, grandmothers and grandfathers often experience and approach caregiving in distinctly different ways.

In particular, when examining the specific activities undertaken with their grandchildren, there are clear gender distinctions. I found that grandmothers were more likely than grandfathers to engage in hands-on tasks: preparing meals, helping with homework, caring for grandchildren when they are sick, and doing school pick-ups.

Grandfathers, while also involved, tended to participate less in these activities. This is the case even among grandparent couples who lived together and jointly cared for their grandchildren.

The role of wealth

The extent and nature of grandparental care is also closely linked to grandparents’ socioeconomic status. For example, grandparents with fewer financial resources tended to offer childcare more regularly than their wealthier counterparts.

Socioeconomic disparities also shape the nature of caregiving tasks. Less affluent grandparents were more likely to engage in hands-on activities, such as cooking meals and taking their grandchildren to and from school. In contrast, grandparents with more education were more likely than those with less education to help with homework frequently.

The reasons for providing care also varied according to grandparents’ socioeconomic status. Grandparents with greater financial resources and higher levels of education were more likely to report providing childcare to help parents manage work and other responsibilities, as well as to offer emotional support to their grandchildren. Conversely, those with fewer financial resources were more likely to feel obliged to help or to struggle to refuse caregiving duties.

Grandparent wellbeing

What grandparents do with their grandchildren and why they have an active role in caring for them can also affect their wellbeing in complex ways. Grandparents who often took part in fun or enriching activities with their grandchildren, such as leisure activities or helping with homework, tended to report higher wellbeing compared to their peers who did not look after grandchildren.

However, grandparents who cared for their grandchildren when they were sick or who had them stay overnight without parents tended to report, over time, lower wellbeing.

Motivations also matter for grandparents’ wellbeing. Grandparents had a higher quality of life if they cared for their grandchildren because they wanted to help them develop as people, or to feel engaged with young people. However, grandparents who felt obliged to help, perhaps due to family pressure or lack of alternatives, experienced lower wellbeing.

In short, these findings remind us that behind the broad label of “grandparenting” lies a diverse world of individuals whose involvement in caring for grandchildren – how often they care, what they do, and why – is closely linked to and varies with gender norms and socioeconomic status.

Also, the meaning behind grandparenting and the type of interactions shared with grandchildren seems to matter for grandparents’ wellbeing. Overall, these insights suggest that these caring responsibilities may contribute to the reinforcement or even deepening of existing gender, socioeconomic and health inequalities among older adults.

Restrictive practices in mental health settings – such as physical restraint and seclusion – are meant to be a last resort, used only when patients pose a risk to themselves or others.

In 2021 and 2022 alone, NHS England reported that 6,600 mental health patients were subjected to physical restraint, and 4,500 to seclusion. Figures such as these have led numerous experts and policymakers to conclude that restrictive practices are overused in mental health inpatient settings.

The consequences can be devastating. Restrictive practices are associated with trauma, worsening mental health, and even death. For decades, clinicians, researchers and policymakers have called for their reduction. Progress, however, remains painfully slow.

For the past five years, I have been researching the use of restrictive practices in mental health services and exploring how to reduce them. My new research demonstrates the importance of using compassion to support staff to promote the dignity and wellbeing of patients as a priority.

Restrictive practices have a long history that predates the development of asylums and psychiatry as a medical discipline. The use of legislation to detain people on the basis of their mental health in England, for example, dates back to at least the 14th century. Early examples of restrictive practices included patients being bound and beaten with rods in order to “restore sanity”.

During the first three decades of the 19th century, mechanical restraints such as straitjackets, chains and restraint chairs and confining patients in locked rooms were widely accepted methods of controlling violent people in British asylums. But in the 1830s, some clinicians recognised the moral and ethical problems with using such practices, and a campaign began to abolish them.

The UN has long recognised restrictive practices in mental healthcare as a human rights issue. In 2008, the UN’s special rapporteur on torture stated that methods such as solitary confinement violate articles 14 and 15 of the Convention on the Rights of Persons with Disabilities, which protect against arbitrary detention and cruel, inhuman or degrading treatment.

This stance was reaffirmed in 2021 when the UN declared that restrictive practices breach the fundamental rights of patients. This underscores the urgent need for reform in mental healthcare systems worldwide.

Harmful effect

Research shows that restrictive practices may not only harm patients but contradict the goals of mental healthcare. Many mental health problems stem from traumatic experiences that leave people feeling powerless, unsafe and distressed. Using methods that reinforce these feelings can worsen the very issues services aim to address.

In extreme incidents, people have died as a result of restrictive practices use.

In my research, I have developed a theoretical model identifying core factors that perpetuate the use of restrictive practices in mental health services. These include the emotional challenges faced by staff working in high-stress environments, and how these challenges influence their decision-making.

Mental health wards can be highly stressful environments, with frequent incidents of aggression. In such settings, staff can often feel anxious and hyper-vigilant, which can make it harder for them to respond to patients with compassion.

Research shows that threat-based emotions like fear and anger are linked to a greater likelihood of using restrictive measures. So, this cycle perpetuates the use of these harmful practices.

Compassion may hold the key

Using restrictive practices to control or remove people who are perceived as a threat can provide staff with a sense of immediate safety, which may inadvertently reinforce their use. To address this, I wanted to explore whether supporting staff to manage their emotions more effectively could reduce their reliance on restrictive practices, and foster a more compassionate approach to care.

As part of my research, I introduced compassion-focused support groups for staff in several forensic mental health wards, advocating for a more empathetic and patient-centred approach. These groups tried to equip participants with skills to better manage challenging emotional experiences while fostering greater compassion for both themselves and the people in their care.

The aim was to help staff cultivate an inner sense of safety, reducing their reliance on restrictive practices as a means of managing their own feelings of threat. This intervention was encouraging, leading to reductions in the use of restrictive practices in some conditions – demonstrating the potential of using compassionate care for these purposes.

My study was the first of its kind – bur these initial results highlight the need for further research into how the emotional management of staff influences care decisions. The journey toward change is slow, but it is possible. Compassion may hold the key to addressing a deeply entrenched issue that has shaped the treatment of mental health patients for centuries.

Despite the steady growth of online shopping, a majority of the UK public still prefers to buy groceries at the supermarket.

Shopping trolleys can help us lug our purchases back to the car, but some shoppers are evidently taking them further afield. In 2017, 520,000 trolleys were reported as abandoned in the UK. Sunderland in north-east England alone reported 30,000 abandoned trolleys between 2020 and 2022. Likewise, 550 trolleys were collected in a single day in western Sydney, Australia.

Supermarkets employ a range of methods to stop trolleys leaving their premises, including coin slots, vertical bars (to stop trolleys leaving the shop floor), wheel-locking mechanisms and car park wardens. Despite these efforts, abandoned trolleys still blight the landscape and need to be collected.

Many supermarkets use commercial collection services, such as Wanzl TrolleyWise or TMS Collex. These companies typically use diesel vans to survey suburban areas, collect trolleys and return them to supermarkets. They also offer to refurbish weathered or damaged trolleys, sometimes by applying a zinc-based coating to protect against corrosion – a process known as regalvanisation.

We are researchers at the University of Warwick who wanted to understand the environmental impact of trolley abandonment. So, we set out to investigate it.

Collecting versus manufacturing

How does the environmental impact of using vans to rescue abandoned trolleys compare with losing these trolleys to excessive damage or corrosion and having to make new ones?

Our study used a standardised methodology known as life-cycle assessment to analyse the potential environmental impact of collecting and handling abandoned shopping trolleys within an area of Coventry, a city in the English West Midlands, which includes our university campus.

We spoke to trolley suppliers, who told us trolleys used at the supermarket in Coventry were most likely made in Spain. This was incorporated into our model.

Through conversations with our university’s estates department and commercial collection services, we established that approximately 30 trolleys were collected a week on average in the area surrounding the Tesco supermarket in the Cannon Park shopping centre.

Our model assumed that a bulk transport of 50 trolleys is sent twice each year to be refurbished, in a round trip of 220km between Coventry and a refurbishment facility based in the UK that was noted on stickers placed on refurbished trolleys.

Vans collecting 520,000 abandoned trolleys in a year could emit the equivalent of 343 tonnes of CO₂ (the annual equivalent of driving 80 petrol cars). If we imagine that 10% of these 520,000 trolleys have been left outside too long and need to be regalvanised then the total global warming impact increases by 90% to the equivalent of 652 tonnes CO₂ (roughly the same as 152 petrol cars being driven for one year).

This is quite a surprising increase for such a small number of trolleys. It suggests that the real problem lies with the environmental impact of manufacturing.

Most of the emissions can be avoided

We found that one trolley would have to be collected 93 times by a diesel van to have the same environmental impact as manufacturing a new one.

Our results showed that the emissions incurred during the diesel van collection phase were only 1% of the manufacturing impact, and the regalvanisation stage was only 8%. We might wonder whether switching to electrically powered collection vans might help. While the emissions would be reduced, the impact of using diesel vans is still minuscule compared to that of making new trolleys.

We found that the highest environmental impact stemmed from manufacturing, which was mainly attributed to making and replacing the steel frame of the trolley.

These results reinforce the benefits of following the circular-economy principle of keeping trolleys in use for as long as possible, and avoiding manufacturing to replace abandoned ones.

Would anything change if we switched to plastic trolleys? Other researchers have investigated the effect of changing trolley materials and have found that trolleys made of polymers have many benefits compared with steel: they use less material, are less dense (a benefit for collection vans that emit less by driving around lighter products) and do not require protective coatings, which themselves have an environmental impact.

However, if these polymer trolleys were to be sent to landfill (or left to deteriorate in the environment), they could release carcinogenic chemicals, as well as microplastics, as they break down. This leads us back to the importance of keeping products in use.

Abandoning trolleys is bad for the environment, with a potential global warming impact equivalent to 0.69 kg CO₂ for collecting one trolley and returning it to a supermarket. If we multiply this by the potential 520,000 abandoned trolleys a year, this figure becomes quite big.

Preventing trolley abandonment should be a priority not just for supermarkets, but for the general public as well. However, once a trolley is abandoned, it is far better to collect and refurbish it than to let it fall out of use and manufacture a new one, as 92–99% of the environmental impact can be avoided.

While it is unlikely that we can ever stop trolleys being abandoned, we hope that next time people see a trolley in an alley or park bush, the potential environmental impact of losing this trolley to service would be apparent.

Under bright lights, the audience looks at a bare stage on two planes. Below, a small stage is white and empty, occupied only by a table and two chairs. Above, a huge, slanted mirror reflects a bird’s-eye view of the stage to the audience. Three middle-aged figures enter the stage without looking at each other. One lies down, staring into the mirror. One stands and one sits. For the next 70 minutes, they will never hold one another’s gaze.

This is the revival of Sarah Kane’s play 4.48 Psychosis. The production takes place 25 years after the original work, bringing the original cast and creative team back to the Royal Court where the play was first staged – now transferred to The Other Place, a small theatre run by the Royal Shakespeare Company.

It replicates the staging of the original with precision. The same faces are on the same set, making the same gestures. Even the projections of the street outside show cars from the 1990s. And yet, because this is theatre, there are inevitable differences.

The play is a revival and a commemoration. Kane wrote 4.48 Psychosis in the year leading up to her death by suicide in 1999 and completed it during her final stay in a psychiatric hospital. It stages the experience of a suicidal and psychotic mind breaking down.

About a week after sending the play to her agent, Kane ended her own life. A year later, the original production was staged at the Royal Court, directed by her long-term collaborator James Macdonald and starring three young actors: Daniel Evans, Madeleine Potter and Jo McInnes. All three have returned for this revival.

4.48 Psychosis is a highly experimental play. It contains dialogue between doctor and patient, poetry, seemingly psychotic speech, lists and quotations from literature and medical documents. In her aims for the play, Kane was both very open and very specific. She described the play in an interview at Royal Holloway University as an attempt to stage the experience of a mind breaking down:

I’m writing a play called 4:48 Psychosis … It’s about a psychotic breakdown and what happens in a person’s mind when the barriers which distinguish between reality and different forms of imagination completely disappear … you no longer know where you stop and the world starts.

What’s more, through an experimental style, Kane hoped to make her audience experience some of the distress experienced by the mental collapse being staged. She described this as “making form and content one”.

How this strange work was to be staged was to be left up to future creatives. She didn’t specify how many actors should perform the work, or provide references to their age or gender. Kane believed that as a playwright, her job was to write the work, and then let directors figure it out.

The result was that the first performance split the experience of breakdown across three actors. At times, they take on more specific roles such as a patient, a doctor, and a lover or bystander. At others, they all seem to occupy a shared mental reverie.

Since the original production, 4.48 Psychosis has been staged in multiple ways around the world. French actor Isabelle Huppert performed the first French production largely as a monologue in 2005, with occasional lines delivered by Gérard Watkins as a psychiatrist. Recently in the UK it has been transformed into a successful opera in which a six-person ensemble and full orchestra performed the play’s “hive mind”, and has been performed in a plastic box in British Sign Language.

When it was first performed in 2000, a year after Kane’s death, the play left a profound impression on its audiences. It was arguably one of the most brutal, head-on representations of mental illness that had ever been seen in British theatre. Reviews from that first production discuss anxieties about whether the play should be viewed as a “suicide note” – a disturbingly “real” reference to Kane’s death.

Today, such anxieties may seem less relevant. After all, over two decades have passed since Kane’s death, and we are in a very different world when it comes to how we view disclosure of personal struggle. In a culture of mental health awareness campaigns and social media oversharing, the closeness of Kane’s suffering to her work seems less scandalous, and perhaps less unsettling.

At times, this revival feels a bit more like a repetition, or archival reconstruction than a fresh performance. There are moments that feel dated – for example, the use of pixelated projections.

The most compelling moments were where something original was introduced due to the more advanced ages of the actors. In my experience, the play is typically performed by a younger cast, as a rageful, energetic cry of despair. It hits differently with a cast in their fifties.

Madeleine Potter’s resigned, ironic complaints about being mistreated by “Dr This and Dr That” gave the impression of a woman with a lifetime’s experience of inadequate mental health services. And Jo McInnes’s desperate monologue about lost love could be referencing an estranged or dead child, as much as a lover.

These moments inserted something new into Kane’s iconic last work and underlined that mental suffering is far from being the privilege of the young. More of a slow burn than an explosive cry of anger, this return to 4.48 Psychosis explores mental torment that can persist over a lifetime, revealing it to be as relevant as ever.

4.48 Psychosis is at The Other Place until July 27.

Earth’s biodiversity is in crisis. An imminent “sixth mass extinction” threatens beloved and important wildlife. It also threatens to reduce the amount of genetic diversity – or variation – within species.

This variation in genes within a species is crucial for their ability to adapt to changes in the environment or resist diseases. Genetic variation is therefore crucial for species’ long term survival.

Traditional conservation efforts – such as protected areas, measures to prevent poaching, and captive breeding – remain essential to prevent extinction. But even when these measures succeed in boosting population numbers, they cannot recover genetic diversity that has already been lost. The loss of a unique gene variant can take thousands of years of evolution before it is recovered by a lucky mutation.

In a new paper in Nature Reviews Biodiversity, an international team of geneticists and wildlife biologists argues that the survival of some species will depend on gene editing, along with more traditional conservation actions. Using these advanced genetic tools, like those already revolutionising agriculture and medicine, can give endangered species a boost by adding genetic diversity that isn’t there.

Genetic engineering is not new. Plant breeders have used it for decades to develop crops with traits to boost disease resistance and drought tolerance. Around 13.5% of the world’s arable land grows genetically modified crops. Gene-editing tools such as Crispr are also being used in “de-extinction” projects that aim to recreate extinct animals.

The Dallas-based company Colossal Laboratory & Biosciences has attracted headlines for its efforts to bring back the woolly mammoth, dodo and dire wolf. In de-extinction, the DNA of a living relative species is edited (changed) to approximate the extinct species’ most charismatic traits.

For example, to “resurrect” a woolly mammoth, Colossal’s researchers plan to splice mammoth genes (recovered from ancient remains) into the genome of the Asian elephant to produce a cold-hardy, hairy elephant-mammoth hybrid. Colossal recently engineered grey wolf pups with 20 gene edits from the extinct dire wolf’s DNA.

The “Jurassic Park”-style revival of long-gone creatures has attracted considerable attention and funding, which has accelerated the development of genome engineering techniques. These same genome editing tools can be used for conservation of existing and endangered species. If we can edit a mouse to have mammoth hair, or edit a wolf to resemble a dire wolf, why not edit an endangered bird’s genome to make it more resilient to disease and climate change?

Museum specimens

Using DNA from historical specimens, scientists can identify important genetic variants that a species has lost. Many museums hold century-old skins, bones, or seeds – a genomic time capsule of past diversity. With genome editing, it is possible to reintroduce these lost variants into the wild gene pool.

By restoring genetic variation, species can be fortified against emerging diseases and environmental change. A sharp decline in population numbers is called a “bottleneck”. During a bottleneck, inbreeding and genetic drift lead to the random loss of genetic diversity. Harmful mutations can also increase in frequency. Such “genomic erosion” compromises the health of individuals and can make populations more prone to extinction.

If we can pinpoint a particularly damaging mutation that has become widespread in the population or a variant that has been lost, we could replace it in a few individuals using gene editing. Aided by natural selection, the healthy variant would gradually spread in the population.

If a threatened species lacks genes that it desperately needs to survive new conditions, why not borrow them from a close relative that already has those traits? Known as facilitated adaptation, this could help wildlife cope with threats such as climate change.

In agriculture, such cross-species gene transfers are routine. Tomatoes have been engineered with a mustard plant gene to tolerate cold, and chestnut trees got a wheat gene for disease resistance. There is no reason why such techniques cannot be expanded to animals.

These genetic interventions can complement, but never replace traditional conservation measures. Habitat protection, control of invasive predators, captive breeding programmes, and other on-the-ground action remain absolutely necessary. Importantly, gene editing only makes sense if the target population has recovered in numbers enough (often through conservation), to allow natural selection to do its job.

Measuring the risk of extinction

Gene-edited animals or plants wouldn’t have a chance if released into a barren habitat or a poaching hotspot. Genomic tools can give an extra edge to species that are already being saved from immediate threats, equipping them for adaptive evolution in the future.

Climate zones are shifting, new diseases are spreading, and once-isolated populations are cut off in small fragments of habitat. Without intervention, even intensive habitat management might not prevent a wave of extinctions.

However, a strategy of gene editing also comes with significant risks and unknowns. One technical concern is off-target effects – Crispr and other gene-editing techniques might make unintended DNA changes in addition to the intended edit. In other words, you attempt to insert a disease-resistance gene, but accidentally disrupt another gene in the process. Similarly, a gene may have more than one function, which is known as pleiotropy.

Especially in less-well studied species, we may not be aware of all those functions or pleiotropic effects. Regulatory inertia and public scepticism may also present big obstacles – these issues have historically limited the rollout of genetically modified (GM) organisms, particularly in agriculture.

There are also evolutionary and ecological uncertainties. A deliberate gene edit might have knock-on effects on how the species evolves over time. For instance, if one individual is given a highly beneficial gene that spreads rapidly, it could replace all the other gene variants at that location in the genome (the full complement of DNA in the organism’s cell). This is known as a “selective sweep”, and it inadvertently reduces the genetic diversity in that region of the genome.

Some critics argue that the narrative of a genetic quick fix could distract from the root causes of biodiversity loss. If people believe we can simply “edit” a species to save it, will that undermine the urgency to protect habitats or cut carbon emissions? Portraying extinction as reversible might seed false hope and reduce the motivation for tough environmental action.

Conservation efforts, strong environmental policies and legal protections remain indispensable. So do habitat restoration, climate action and reducing the impact made on the environment by humans.

Nevertheless, genome engineering is a new tool in the conservation toolbox. It’s one that –given the right assistance and environmental encouragement – can help save species from extinction.
