Have you ever wondered why people who nearly die often describe speeding toward supernatural light, or seeing their life flash before their eyes? You may have also heard about the powerful psychedelic dimethyltryptamine (DMT), a class A illegal drug in the UK, and how it might generate the so-called near-death experiences. In a recent study I compared both types of experience and found they share fascinating similarities – but also critical differences.

Some studies have suggested there are some basic overlaps between the experiences people have during a near-death experience and taking DMT. But my doctoral research was the first to make an in depth and nuanced qualitative comparison between DMT trips and NDEs. It was also the first field study of its kind, capturing authentic experiences instead of asking participants to take DMT in a laboratory.

Thirty-six participants took vaporised high-dose DMT, typically inhaled from a glass pipe, in familiar settings like their own homes. My colleagues and I used an interviewing technique inspired by micro-phenomenology, a new scientific approach which aims help people discover ordinary but inaccessible dimensions of our lived experience.

This approach helps interviewees recall details of their experience by asking them to articulate it moment by moment in their own words and in chronological order, while expanding out different dimensions such as sensory or emotional experiences.

This allowed us to explore the experiences with greater granularity. For example, in what way the general themes, such as meeting unusual beings or feeling yourself dissolve entirely, specifically expressed itself.

It also allowed us to measure how often each type of these details occurred. We then compared these descriptions to our analysis of another team’s raw data from their 2018 publication studying 34 cardiac arrest-induced NDEs.

My study found both types of experiences also had important differences which researchers have previously overlooked.

People in both groups commonly reported feeling detached from their bodies, encountering beings, travelling through mysterious spaces such as tunnels or voids, and seeing bright lights. These shared experiences hint at similar brain processes at play, like disruptions in the parts of the brain that handle the map of our body, how we simulate other people’s perspectives, sensory perception and spatial processing.

However, DMT trips almost never involved the more classic NDE “life review”, or dramatisations of experiencers’ return to life as in encountering a symbolic threshold of no return. Conversely, NDEs virtually never entailed the visuals of complex geometric patterns iconic to the DMT trip.

The most compelling difference, however, was in the way these features were represented. For example, while people with NDEs frequently reported meeting dead loved ones, DMT users universally described encounters with otherworldly or alien beings.

Suddenly finding yourself transformed into a spirit witnessing your body from above, before being greeted by a guide seemed to be characteristic of NDEs. DMT would simply dissolve people’s bodily awareness, as they rapidly shot into a transcendent world inhabited by mechanical clowns or serpentine scientists.

My colleagues and I suggest that a blend of shared brain biology and personal psychology may explain why these experiences are so similar in their generic elements but differ in their content.

Some especially intriguing phenomena in NDEs, such as the “Peak in Darien” experience where the dying see others they did not know were dead, or correctly perceive things in their surroundings when out of body, are not yet fully explained by neuroscience. B

ut the common features mentioned above probably come directly from how DMT or the near-death state affects our brains. Think of these as universal stage props, set by our brain’s biology. But the stories we attach to these props – seeing your dead aunt or a multi-eyed octopoid alien – are influenced by our personal backgrounds, cultural expectations and memories.

DMT and the brain

Early psychedelic researchers suggested that DMT might flood the brain. during near-death conditions. But life isn’t that simple – and nor is death.

Studies have shown, for example, that rats produce DMT not only via their pineal glands, but in their cortical tissue, including at the point of death. But there isn’t yet evidence that this happens in human brains. Even if humans do produce DMT at psychoactive quantities in the throes of dying, our body’s enzymes could break it down before it reaches or has enough impact on the brain. Additionally, serotonin surges dramatically when you’re under extreme stress, which may itself confer psychedelic effects – and also sticks to the serotonin receptor more happily than DMT, possibly eclipsing any DMT activity.

All this said, some scientists argue the measuring methods used to measure rat brain DMT during cardiac arrest might miss short-lived, higher DMT spikes throughout the brain. And some researchers also think damage to certain neural networks and oxygen deprivation near death might amplify DMT’s psychedelic effects.

Interestingly, our study also discovered a subset of near-death experiences that lacked the imagery of a prototypical NDE, and instead presented abstract, cosmic visions more typical of DMT trips. It’s not easy to say where these atypical NDEs could be coming from. But it could be when someone has less preconceptions of NDEs or greater preconceptions of a psychedelic trip. Perhaps their body was synthesising higher levels or DMT than is usual for an NDE. The next frontier of this research would be to track brain activity when general features crop up. We also need more research to explore potential psychological and cultural reasons why these features are expressed in the way that they are.

Many indigenous people around the globe may feel contemporary science is superfluous. Ayahuasca, a shamanic brew that contains DMT, has been used by tribes all over the Amazon to connect to the spirit world and commune with their ancestors.

People who have an NDE almost always feel their fear of death lift afterwards. Since DMT reproduces many aspects of NDEs, it could become a powerful therapeutic tool (alongside psychological support) particularly for people facing existential anxiety or fear of death, whether they are terminally ill or physically healthy. Scientists are already exploring whether ayahuasca may treat prolonged grief disorder.

We’re just starting to demystify what the implications of DMT – this “mystical” substance – may be.

The phrase “summer long balls” might sound like locker-room slang, but it’s increasingly being mentioned on social media and online forums as a seasonal curiosity. In hot weather, men’s scrotums which contain their testicles can appear looser or more pendulous – hence the name.

Male readers may have noticed how the testes sometimes seem to hang lower in the summer, yet retreat upwards with the slightest cooling breeze. (I’ll stick with the term testes for anatomical accuracy, although we all know the slang terms are many and varied.)

While you may think of rising and falling as the domain of soufflés, when it comes to testes, their ability to move up and down is a key part of an elegant, biological temperature-control system.

For some, low-hanging testes are simply a cosmetic issue affecting swimwear choices or confidence, but others can suffer discomfort. Supportive underwear may help, although finding the right fit might require more effort than your average trip to Calvin Klein.

To understand what’s going on in male bodies, we need to go back to the beginning. Both testes and ovaries start life in the abdomen and migrate downward. But whereas the journey for ovaries stops in the pelvis, testes go further, exiting the abdominal cavity entirely to reside in the scrotum – a move that’s crucial for sperm production.

The testes produce and mature sperm cells and generate androgens, such as testosterone, which govern sexual development and behaviour. These processes are temperature-sensitive. Inside the pelvis is too warm for optimal sperm production – hence the descent to the cooler scrotum, usually in teenage years when your “balls drop”.

But to reach the scrotum, testes must pass through layers of the abdominal wall. Sometimes this journey doesn’t go as planned, resulting in an undescended testis, where one (or both) remain stuck in the abdomen or groin. Surgery may be required to correct this.

Even when testes do land in the right place, they don’t stay still. The scrotum and surrounding tissues adjust their position in response to temperature. That’s where the cremasteric muscle comes in. Found within the spermatic cord, it can contract and pull the testes closer to the body when needed – for warmth and perhaps protection.

One strange but testable reflex? Try stroking the inner thigh. If functioning normally, the testis on that side will rise slightly. This reflex can also be affected by neurological disease or testicular torsion, a surgical emergency.

The dartos muscle, located in the scrotal wall, plays a similar role. When temperatures drop it contracts, drawing the testes up for warmth. In heat, it relaxes – lowering the testes and helping them cool off.

Fertility issues

This thermal sensitivity is critical for fertility. Sustained overheating can impair sperm quality, which is why an undescended testis stuck in the abdomen or groin requires an operation.

Similarly, men who are struggling to conceive may be advised to avoid tight underwear or cycling shorts, switch to looser boxers, and reduce time spent cycling because of saddle friction.

The heat, pressure and tight fit of padded cycling shorts have all been suggested as potential risks to sperm health – though the evidence remains inconclusive. It’s not necessarily the padding but rather the compression and sustained heat in the groin area that may affect testicular function.

Temperature regulation doesn’t stop there. The pampiniform plexus, a network of veins around the testicular artery, acts like a radiator. It draws heat from arterial blood to cool it before it reaches the testes, preventing overheating.

Sometimes, these veins swell into a varicocele — a condition often described as feeling like a “bag of worms”. It becomes more noticeable when standing and affects around 15% of men. While often harmless, this can also affect fertility through loss of heat regulation. Some patients may also notice a dull ache in the testes, particularly after exercise or at the end of the day.

So, “summer long balls” are rooted in real physiology. During hot weather, a relaxed dartos muscle and loose scrotal skin allow the testes to hang lower – sometimes enough to notice a visible difference. If that’s true for you, this isn’t a malfunction but your body doing exactly what it’s supposed to. While this condition might sound like something from a comedy sketch, it’s actually a sign your reproductive system is working as nature intended.

After years of multiverse chaos, grim antiheroes and morally ambiguous storylines, superhero films are making a striking return to their emotional and ideological roots. The new iterations of DC’s Superman and Marvel’s The Fantastic Four don’t aim to reinvent the genre – they return to its essence, offering stories grounded in hope, compassion and shared humanity.

Both films are reboots of familiar characters. Zack Snyder’s Man of Steel (2013) was the last major Superman feature, while Josh Trank’s Fantastic Four (2015) attempted – unsuccessfully – to reintroduce Marvel’s “first family”. These 2025 versions step away from the darker superhero tones popularised by Christopher Nolan’s Dark Knight trilogy to embrace vibrant colours and the idealism that made these heroes beloved in the comic books to begin with.

Whether by coincidence or design, both DC and Marvel are now releasing films that centre on embracing humanity – not in spite of difference, but through it. These stories reassert a message comic books have long championed: that community, support and acceptance are strengths. In doing so, they offer a powerful response to the social and political uncertainty of our time.

Superheroes have always functioned as modern myths. Superman, first imagined in the 1930s, was created as a champion of the oppressed. The Fantastic Four, debuting in the 1960s, reflected the spirit of scientific discovery and familial unity.

Their return in 2025 is not just nostalgic. It comes at a moment of cultural significance when war, division and climate anxiety have made many of us question the future. These films don’t ignore that uncertainty, but offer a counterweight: stories that encourage belief in shared values and common purpose.

By reintroducing these characters with sincerity and emotional depth, studios are making a clear bet – that audiences are ready for hope again. And that doing the right thing still matters.

James Gunn’s Superman is a story about an alien learning to live among humans – not by distancing himself but by embracing vulnerability. The film puts moral clarity front and centre. Superman is no longer a distant figure. Instead, he is someone who chooses to believe in others. At one point, he says:

I am as human as anyone. I love, I get scared. I wake up every morning and, despite not knowing what to do, I put one foot in front of the other and try to make the best choices I can. I screw up all the time, but that is being human – and that’s my greatest strength.

This isn’t just sentimental. It’s a direct appeal to audiences facing a fractured world – to act with courage even in uncertainty, and to see all human life as worth protecting.

Marvel’s Fantastic Four reboot, First Steps, takes a similar approach. Rather than leaning into internal conflict, it reintroduces the team as a compassionate, collaborative unit. When the group faces a global threat, Sue Storm (Vanessa Kirby) reframes the challenge: “We will face this together, we will fight this together, and we will defeat this together – as a family.”

It’s a message not only to her teammates but to the world – framing difference as a strength, and unity as the path forward.

A genre renewed

Talk of superhero fatigue has grown in recent years. Some of that stems not from the heroes themselves, but from content overload and diminishing emotional stakes. When continuity outweighs character, even the most powerful icons can feel hollow.

But the return of Superman, the first superhero, and the Fantastic Four, the first superhero family, suggests the genre still has something meaningful to say – especially when it remembers what made it powerful. These characters remind us that heroism isn’t about perfection but perseverance – and that strength comes from empathy.

Other recent superhero films, such as DC’s The Batman (2022) and Marvel’s Thunderbolts* (2025), show that darker, emotionally complex stories remain powerful. They reflect real anxieties – climate crisis, political instability and distrust in institutions. These films resonate because they hold up a mirror to the world.

But there is also space – and perhaps a growing need – for stories that offer reassurance. Superman and The Fantastic Four present an alternative emotional truth: that even in fear and division, goodness, unity and belief in others remain possible. These films don’t reject complexity, they complement it. Where darker stories help us process uncertainty, these hopeful ones remind us of what we can still strive for.

Rather than being competing directions for the genre, these different approaches enrich it. One shows the world as it is; the other, the world as it could be.

The UK will formally recognise the state of Palestine in September unless Israel acts to end the “appalling situation” in Gaza. After an emergency cabinet meeting, Downing Street released a statement saying the UK would recognise Palestine unless Israel committed to a long-term sustainable peace, allowed the UN to restart humanitarian support, agreed to a ceasefire, and made clear there would be no annexations in the West Bank.

The statement also reiterated the UK’s demand for Hamas to release all remaining Israeli hostages, accept a ceasefire, disarm and play no further part in the government of Gaza.

The UK’s decision follows a pledge by French president Emmanuel Macron on July 24 to formally recognise Palestinian statehood statehood in September. If this is acted upon, France and the UK would be the first G7 members and the first members of the UN security council to recognise the state of Palestine.

Recognition of statehood is not merely symbolic. The Montevideo convention of 1933 established several criteria which must apply before an entity can be recognised as a sovereign state. These are a permanent population, a defined territory, an effective government and the ability to conduct international relations.

The process involves the establishment of formal diplomatic relations, including the opening of embassies, the exchange of ambassadors, and the signing of bilateral treaties. Recognition also grants the recognised state access to certain rights in international organisations. For Palestinians, such recognition will strengthen their claim to sovereignty and facilitate greater international support.

This decision by France and the UK is significant. It signals a departure from the western consensus, long shaped by the US and the EU, that any recognition of Palestinian statehood must be deferred until after final-status negotiations. The move also highlights growing frustration in parts of Europe with the ongoing violence in Gaza and the failure of peace talks over the past two decades.

Yet questions remain: what does this recognition actually entail? Will it change conditions on the ground for Palestinians? Or is it largely symbolic?

So far, the French and British governments have offered no details on whether recognition would be accompanied by concrete measures. There has been no mention of sanctions on Israel, no indication of halting arms exports, no pledges of increased humanitarian aid or support for Palestinian governance institutions. France and the UK remain key military and economic partners of Israel, and the pledges do not appear to alter that relationship.

Nor is this the first time western countries have taken a symbolic stance in support of Palestinian statehood. Sweden recognised the state of Palestine in 2014, becoming the first western European country to do so. It was followed by Spain in 2024.

However, both moves were largely symbolic and did not significantly alter the political or humanitarian situation on the ground. The risk is that recognition, without action, becomes a gesture that changes little.

Macron’s statement also raised eyebrows for another reason: his emphasis on a “demilitarised Palestinian state” living side-by-side with Israel in peace and security. While such language is common in diplomatic discourse, it also reflects a deeper tension.

Palestinians have long argued that their right to self-determination includes the right to defend themselves against occupation. Calls for demilitarisation are often seen by critics as reinforcing the status quo, where security concerns are framed almost exclusively in terms of Israeli needs.

In the absence of a genuine political process, some analysts have warned that recognition of this kind risks formalising a state in name only – a fragmented, non-sovereign entity without control over its borders, resources or defence. Without guarantees of territorial continuity, an end to the expansion of Israeli settlements and freedom of movement, statehood may remain an abstract concept.

What would meaningful support look like?

If the UK and France want to go beyond symbolism, they have options. They could suspend arms exports to Israel or call for an independent international investigation into alleged war crimes. They could use the influence on the world stage to push for greater accountability regarding illegal settlements and the blockade of Gaza. They could also support Palestinian institutions directly and engage with Palestinian civil society.

Without such steps, recognition risks being viewed as a political message more than a policy shift. For Palestinians, the daily realities of occupation, displacement and blockade will not change with diplomatic announcements alone. What is needed, many argue, is not just recognition but support for justice, rights and meaningful sovereignty.

The pledged recognition of Palestine by France and the UK marks a shift in diplomatic tone and reflects broader unease with the status quo in the Middle East. It has stirred debate at home and abroad, and raised expectations among those hoping for more robust international engagement with the conflict.

Whether this recognition leads to meaningful changes in policy or conditions on the ground remains to be seen. Much will depend on the steps the UK and France take next – both at the United Nations and through their actions on trade, security and aid.

This article has been updated to include the UK’s pledge to recognise Palestine as well as France’s.

There are masked men, and some women, on the streets in American cities, sometimes travelling in unmarked cars, often carrying weapons and wearing military-style kit. They have the power to identify, arrest, detain non-citizens and deport undocumented immigrants. They also have the right to interrogate any individual who they believe is not a citizen over their right to remain in the US.

These are agents from US Immigration and Customs Enforcement Agency, known as Ice. This is a federal law enforcement agency, which falls under the control of the Department of Homeland Security (DHS), and is playing a significant and contentious role in the implementation of Donald Trump’s tough immigration policy.

On the campaign trail Trump promised “the largest domestic deportation operation in American history”. And he is giving Ice more power to deliver his plans.

Since Trump took office in January, Ice funding has been significantly increased. Trump’s “big beautiful bill”, passed by Congress in July 2025, gave Ice US$75 billion (£55 billion) of funding for the next four years, up from around US$8 billion a year.

This funding boost will allow the agency to recruit more agents as well as adding thousands more beds plus extensions to buildings to increase the capacity of detention centres. There is also new funding for advanced surveillance tools including AI-assisted facial recognition and mobile data collection. There’s another US$30 billion going to frontline operations, covering removing immigrants and transport to detention centres.

The president has committed to deporting everyone who is in the US illegally, that is estimated by the Wall Street Journal to be about 4% of the current US population. For the past five months, the numbers of people being picked up by Ice agents has been ticking up fast.

Average daily arrests were up 268% to about 1,000 a day in June 2025, compared with the same month a year earlier. This was also a 42% rise on May 2025, according to data analysis from the Guardian and the Deportation Data Project. However, this is still considerably short of the 3,000 a day ordered by secretary of homeland security Kristi Noem and White House deputy chief of staff Stephen Miller.

Ice’s tactics have already attracted significant criticism. Right-leaning broadcaster Fox News has reported on how masked agents are not showing ID or naming their agency when picking up people in raids. Other reporting has highlighted allegations that American citizens are also sometimes being swept up in the raids.

The agency, currently led by acting director Todd M. Lyons, has three main divisions: the Enforcement and Removal Operations division, which identifies and deports undocumented immigrants as well as manages detention centres. The Homeland Security Investigations, which investigates criminal activities with an international or border nexus such as human trafficking, narcotics, and weapons smuggling. The Office of the Principal Legal Advisor provides legal advice to Ice and prosecutes immigration cases in court.

Lyons claimed that mask wearing was necessary because of Ice agents being “doxed” – when a person’s personal information such as names and home addresses are revealed online without their permission. Assaults on Ice agents have risen, he claimed. DHS data suggested that there were 79 assaults on Ice agents from January to June 2025, compared to ten in the same period in 2024.

Democratic House minority leader Hakeem Jeffries compared mask wearing by Ice agents to secret police forces in authoritarian regimes. “We’re not behind the Iron Curtain. This is not the 1930s.”

ICE has broad power to detain and arrest noncitizens – but is still bound by constitutional limits

The Ice agency was established in 2003 by the George W. Bush administration, partly as a result of the 9/11 terrorist attacks, and was part of a broader reorganisation of federal agencies under the then newly created DHS. It incorporated parts of the former Immigration and Naturalization Service (INS) and some elements of the US Customs Service.

According to the agency’s website, Ice’s core mission is “to protect America through criminal investigations and enforcing immigration laws to preserve national security and public safety”.

What’s changed?

At the start of the administration in January, the White House gave Ice the authority to hasten the deportation of immigrants that had entered the country with government authorisation during the previous administration. This “expedited removal” authority allowed Ice to deport individuals without requiring an appearance before an immigration judge.

As arrests have grown in the past months, Lyons told CBS News that Ice would detain any undocumented immigrant, even if they did not have a criminal record.

And the Trump administration has also allowed Ice agents to make arrests at immigration courts, which had previously been off limits. This restriction was introduced by the Biden administration in 2021 to ensure witnesses, victims of crimes and defendants would still appear in court without fear of arrest for immigration violations, unless the target was a national security threat.

However, Lyons rescinded those restrictions in May, part of a broader shift towards aggressive enforcement.

Much of the time, Ice has targeted illegal immigrants. But the agency has also arrested and detained some individuals who were residents (green card holders) or tourists – and, in some cases, citizens.

In recent weeks, according to the Washington Post, Ice has been ordered to increase the number of immigrants shackled with GPS-enabled ankle monitors. This would significantly increase the number of immigrants that are under surveillance. Ankle monitors also restrict where people can travel.

Sparking protests

There have been numerous public protests about Ice raids, most notably in California. This peaked on June 6 after Ice had conducted numerous raids in Los Angeles, resulting in clashes between agents and protesters. This led to the White House sending around 2,000 National Guard troops and 700 Marines to Los Angeles, despite opposition from California governor Gavin Newsom.

Part of the friction between the Trump administation and the state is that Los Angeles and San Francisco have adopted local policies to limit cooperation with federal immigration authorities including Ice. California has sanctuary laws, such as SB 54, that prohibit local police and sheriffs from assisting Ice with civil immigration enforcement.

However, Trump shows every sign of pushing harder and faster to crack down on illegal immigrants, and Ice agents are clearly at the forefront of how he aims to do it.

Is there a massive undiscovered planet on the outer reaches of the Solar System? The idea has been around since before the discovery of Pluto in the 1930s. Labelled as planet X, prominent astronomers had put it forward as an explanation for Uranus’s orbit, which drifts from the path of orbital motion that physics would expect it to follow. The gravitational pull of an undiscovered planet, several times larger than Earth, was seen as a possible reason for the discrepancy.

That mystery was ultimately explained by a recalculation of Neptune’s mass in the 1990s, but then a new theory of a potential planet nine was put forward in 2016 by astronomers Konstantin Batygin and Mike Brown at Caltech (the California Institute of Technology).

Their theory relates to the Kuiper Belt, a giant belt of dwarf planets, asteroids and other matter that lies beyond Neptune (and includes Pluto). Many Kuiper Belt objects – also referred to as trans-Neptunian objects – have been discovered orbiting the Sun, but like Uranus they don’t do so in a continuous expected direction. Batygin and Brown argued that something with a large gravitational pull must be affecting their orbit, and proposed planet nine as a potential explanation.

This would be comparable to what happens with our own Moon. It orbits the Sun every 365.25 days, in line with what you would expect in view of their distance apart. However, the Earth’s gravitational pull is such that the Moon also orbits the planet every 27 days. From the point of view of an outside observer, the Moon moves in a spiralling motion as a result. Similarly, many objects in the Kuiper Belt show signs of their orbits being affected by more than just the Sun’s gravity.

While astronomers and space scientists were initially sceptical about the planet nine theory, there has been mounting evidence thanks to increasingly powerful observations that the orbits of trans-Neptunian objects are indeed erratic. As Brown said in 2024:

I think it is very unlikely that P9 does not exist. There are currently no other explanations for the effects that we see, nor for the myriad other P9-induced effects we see on the Solar System.

In 2018, for example, it was announced that there was a new candidate for a dwarf planet orbiting the Sun, known as 2017 OF201. This object measures around 700km across (Earth is roughly 18x bigger) and has a highly elliptical orbit. This lack of a roughly circular orbit around the Sun suggested either an impact early in its lifetime that put it on this path, or gravitational influence from planet nine.

Problems with the theory

On the other hand, if planet nine exists, why hasn’t anyone found it yet? Some astronomers question whether there’s enough orbital data from Kuiper objects to justify any conclusions about its existence, while alternative explanations get put forward for their motion, such as the effect of a ring of debris or the more fantastical idea of a small black hole.

The biggest issue, however, is that the outer Solar System just hasn’t been observed for long enough. For example, object 2017 OF201 has an orbital period of about 24,000 years. While an object’s orbital path around the Sun can be found in a short number of years, any gravitational effects probably need four to five orbits to notice any subtle changes.

New discoveries of objects in the Kuiper Belt have also presented challenges for the planet nine theory. The latest is known as 2023 KQ14, an object discovered by the Subaru telescope in Hawaii.

It is known as a “sednoid”, meaning it spends most of its time far away from the Sun, though within the vast area in which the Sun has a gravitational pull (this area lies some 5,000AU or astronomical units away, where 1AU is the distance from the Earth to the Sun). The object’s classification as a sednoid also means the gravitational influence of Neptune has little to no effect on it.

2023 KQ14’s closest approach to the Sun is around 71AU away, while its furthest point is about 433AU. By comparison, Neptune is about 30AU away from the Sun. This new object is another with a very elliptical orbit, but it is stabler than 2017 OF201, which suggests that no large planet, including a hypothetical planet nine, is significantly affecting its path. If planet nine exists, it would therefore perhaps have to be farther than 500AU away from the Sun.

To make matters worse for the planet nine theory, this is the fourth sednoid to be discovered. The other three also exhibit stable orbits, similarly suggesting that any planet nine would have to be very far away indeed.

Nonetheless, the possibility remains there could still be a massive planet affecting the orbits of bodies within the Kuiper Belt. But astronomers’ ability to find any such planet remains somewhat limited by the restrictions of even unmanned space travel. It would take 118 years for a spacecraft to travel far enough away to find it, based on estimates from the speed of Nasa’s New Horizons explorer.

This means we’ll have to continue to rely on ground- and space-based telescopes to detect anything. New asteroids and distant objects are being discovered all the time as our observing capabilities become more detailed, which should gradually shed more light on what might be out there. So watch this (very big) space, and let’s see what emerges in the coming years.

What does masculinity have to do with the climate? A surprising amount.

For example, significant figures in the manosphere combine misogyny with anti-environmentalism. Think Andrew Tate boasting of his fleet of cars and his private jet. And because care is central to climate action, it may be seen as “women’s work”.

I recently spoke at a panel event in Newcastle, organised by The Conversation and youth charity Cumberland Lodge, on youth, masculinity and the political divide. The sheer breadth of the discussion – between academics and teenage members of NE Youth on the panel and members of the audience – show how messages and beliefs about gender roles and masculinity are embedded in so many aspects of society and our lives.

My research explores what academics call ecological masculinities. This recognises that there are gender and class expectations of who takes the lead in climate action, like the ones I mentioned.

When young, working-class men – many of whom have never been invited into environmentalism before – get involved with climate action, this is more than helping the environment. It’s reshaping perceptions of who gets to play a caring role, including environmental care.

As part of my research, I’m working on the National Lottery Climate Action Fund project Birds, Bees, Bikes and Trees. This is a partnership between Gateshead’s Baltic Centre for Contemporary Art and North East Young Dads and Lads, a regional charity working with young fathers and their families. Through the project, young men get involved in planting trees, making pollinator habitats, and learning skills in bicycle maintenance.

In listening to the young men at the project launch of Birds, Bees, Bikes and Trees I learned that they live their lives locally. They do not go on holidays abroad. They visit local shops and the vast majority do not own a car – they walk, cycle or take public transport.

But they are not commended for their green citizenship. Instead, they are often marked by poverty and deprivation. This view, which sees them as lacking, consigns their demographic to marginalisation. They are seen as without education and without opportunity. It also helps explain why private car ownership is seen as aspirational.

Many areas of north-east England can be considered “left behind places”. At the panel event, attendees talked eloquently about how in their communities, stories of their hometown’s past industrial successes have become their inherited legacies. The decline of traditional industries, often associated with traditional ideas of masculinities, has created generational gaps, a vacuum in identity and purpose.

Opening up environmental care to young men brings opportunities. I am one of a team of beekeepers who tend to two beehives on the south facing roof of the Baltic.

These hives are managed by the North East Young Dads and Lads. Due to conditions at this site – looking after bees at 42 metres in the air – the young men are offered extra training that provides them with industrial skills, in this case industry standard health and safety certification for harness and lanyard working. This adds value to the their ecological efforts.

Young men involved in the project have become employed as beekeepers and cycling coordinators, as well as trained in bike maintenance, forest school leadership and outdoor first aid.

In the North East, though, environmental work has suffered a setback. Durham County Council – now run by Reform UK – has announced they’re removing the words equality and climate change from department names and have rescinded their climate emergency declaration.

This reflects the views of many Reform voters, who – according to YouGov polling – don’t see the environment as a key issue affecting the country.

But the net zero economy in the UK is already four times the size of the manufacturing sector. Challenging the narrative on masculinity – its relationship to caring, and to traditional forms of work – is beneficial for young men. One dad, now employed on the project as a community beekeeper and cycling coordinator, said:

Being more in touch with nature, not only the bees but the flowers and trees they forage on, has been an amazing experience … I see myself as a human worker bee in partnership with these fantastic little creatures, helping them produce a surplus of honey.

Planting trees, restoring bikes, inspecting bee hives and looking after green spaces isn’t just environmental work. It’s emotional work. It’s care work. And changing the narrative on who gets to do it is vitally important.

The last few months have been busy for Royal Mail. In late April, Czech businessman Daniel Kretinsky’s EP Group acquired its parent company, International Distribution Services, for £3.6 billion – a value well below the May 2021 peak of £6 billion.

Then, regulator Ofcom announced that from July 28 there would be changes to a regulatory framework called the universal service obligation (USO). This effectively determines delivery standards for Royal Mail – and has been seen as a major barrier to its profitability. The company, which was privatised in 2013, made an adjusted operating loss of £348 million in 2023-24 (and £419 million in 2022-23).

So what do the events of the past few months mean for its future?

It has seen letter volumes fall from a peak of 20 billion in 2004-5 to only 6.6 billion in 2023-24. At the same time, parcel volumes have grown to 3.9 billion – driven by a rise in home shopping. However, Royal Mail has struggled to manage this shift and maintain profitability, effectively downsizing letter infrastructure and rebalancing its workforce to reflect this.

Meanwhile, the costs of meeting its USO obligations have meant its performance has deteriorated. There is competition in letters – but only for the most profitable business. Delivery company Whistl collects and processes bulk business mail and pays Royal Mail to deliver “the last mile”. But Whistl sits outside the USO and can cherry-pick its market segment.

The new USO still requires Royal Mail to deliver first-class letters six days a week, but second-class deliveries will now be on alternate weekdays only. Parcel deliveries are five days a week. Crucially, the obligation applies to around 32 million UK addresses – all for the same price.

The target for delivering first-class post within one day is falling from 93.5% to 90%. For second-class, the three-day target is falling from 98.5% to 95%. There’s also a new target – 99% of all post must arrive no more than two days late.

In making these changes, Ofcom is seeking to strike a balance between reliability, affordability and sustainability. It believes the changes will save Royal Mail between £250 million and £425 million a year, ensuring the service will break even and continue.

However, the company’s 2024-25 performance is below the new targets (76.5% for first-class and 92.2% for second class). As such, it’s likely to come in for more fines from Ofcom to add to those totalling £16 million for the previous two years.

In addition, its ability to increase revenue by raising prices might be curtailed. Second-class prices are regulated – increases are linked to affordability and inflation. They have risen by 74% since 2013, while first-class prices are unregulated and increased by 183%. For comparison, inflation was around 40% over the same period.

Ofcom has said it may also regulate first-class costs, amid concerns that Royal Mail may raise them to such a level that demand disappears, leaving only second-class post.

Change must come

Despite growth, Royal Mail’s parcels business faces headwinds – its market share fell from 45% in 2014-15 to 35% in 2023-24. Competitors, including FedEx, DHL, Evri, DPD and Amazon are not encumbered by USO obligations. This means they can be leaner and more aggressive in their pricing.

In 2020, Royal Mail lost its monopoly with the Post Office, which now also offers services from Evri and DPD. These two companies recently announced a merger, which is awaiting approval by regulator the Competition and Markets Authority but could create a company delivering more than a billion parcels a year.

In addition to modernising sorting offices, Royal Mail will quickly need to adopt technology such as smart postboxes and parcel lockers in order to compete – but for now it is well behind. A recent contract with supermarket Sainsbury’s to put lockers in stores is a good start, but Royal Mail has only 1,500 lockers compared to Amazon’s 5,000 and Inpost’s more than 7,500.

The impact of the EP Group takeover may take some time to be realised. The guarantees given to the government and unions to get the deal done will limit the extent of change for the first few years. Key assurances include maintaining the USO (whatever form that might take) and regulatory compliance, as well as keeping headquarters and tax residency in the UK.

On top of this, it must also protect the brand, reinvest any pension surplus into Royal Mail, and it cannot sell off or break up the company, outsource services or make compulsory redundancies.

These legally binding commitments, supported by a government “golden share” with some veto powers, are not open-ended. Most are valid for five years but that of no compulsory redundancies was originally valid only until 2025. What happens after they expire is uncertain, but the business has to change significantly. Kretinsky has spoken of the need to modernise to keep pace with competitors. This means there will have to be significant change – sooner rather than later.

Improving productivity will be key, and that is very likely to mean redundancies and changes to work practices. Royal Mail’s management faced a series of damaging strikes in 2022 and 2023. But Kretinsky has sought to work with unions, principally the Communication Workers Union.

He has reached a three-year pay deal with greater job security. But efficiency needs to be improved if Royal Mail is to become profitable – and in a labour-intensive business that could mean difficult decisions and fewer employees.

What Royal Mail has in its favour however is its status as a trusted brand (although recent delivery performance may have tarnished that in some customers’ eyes). Changes to the USO will help in the short term. But the volume of letters will continue to fall and the company’s success will still depend on its ability to match capacity with demand while achieving its targets.

Further USO changes are inevitable. And so is the demise of first-class post, as price increases render it a low-volume, uneconomic service. The takeover is likely to accelerate change.

The parcels business will probably become an integral part of a pan-European logistics enterprise, alongside EP’s existing ventures and Royal Mail’s sister firm, parcel company GLS. This inevitably leaves the letters side of the company as a much smaller offering – with a very uncertain future.

Emmanuel Macron’s pledge to formally recognise the state of Palestine will make France the first G7 country and member of the UN security council to do so. The question is whether others will follow suit. The UK prime minister, Keir Starmer, is coming under mounting pressure from many of his MPs, and has recalled his cabinet from their summer recess to discuss the situation in Gaza.

Starmer is expected to announce a peace plan for the Middle East this week that will include British recognition of Palestinian statehood. Downing Street sources said recognition was a matter of “when, not if”.

Recognition of statehood is not merely symbolic. The Montevideo convention of 1933 established several criteria which must apply before an entity can be recognised as a sovereign state. These are a permanent population, a defined territory, an effective government and the ability to conduct international relations.

The process involves the establishment of formal diplomatic relations, including the opening of embassies, the exchange of ambassadors, and the signing of bilateral treaties. Recognition also grants the recognised state access to certain rights in international organisations. For Palestinians, such recognition will strengthen their claim to sovereignty and facilitate greater international support.

Macron’s announcement was met with enthusiasm in many Arab capitals, as well as among Palestinian officials and supporters of the two-state solution. It was also praised by a number of European leaders as well as several journalists and other analysts as a long-overdue step toward a more balanced approach to the Israeli-Palestinian conflict.

However, the reaction from other major powers was swift and critical. The US called it “a reckless decision” while the Israeli prime minister, Benjamin Netanyahu, said he “strongly condemned” it. Italy’s prime minister, Giorgia Meloni, called it “counterproductive”.

Within hours, it was clear that Macron’s announcement had both shifted diplomatic discourse and reignited longstanding divisions.

France’s decision is significant. It signals a departure from the western consensus, long shaped by the US and the EU, that any recognition of Palestinian statehood must be deferred until after final-status negotiations. The move also highlights growing frustration in parts of Europe with the ongoing violence in Gaza and the failure of peace talks over the past two decades.

Yet questions remain: what does this recognition actually entail? Will it change conditions on the ground for Palestinians? Or is it largely symbolic?

So far, the French government has offered no details on whether this recognition will be accompanied by concrete measures. There has been no mention of sanctions on Israel, no indication of halting arms exports, no pledges of increased humanitarian aid or support for Palestinian governance institutions. France remains a key military and economic partner of Israel, and Macron’s announcement does not appear to alter that relationship.

Nor is this the first time a western country has taken a symbolic stance in support of Palestinian statehood. Sweden recognised the state of Palestine in 2014, becoming the first western European country to do so. It was followed by Spain in 2024.

However, both moves were largely symbolic and did not significantly alter the political or humanitarian situation on the ground. The risk is that recognition, without action, becomes a gesture that changes little.

Macron’s statement also raised eyebrows for another reason: his emphasis on a “demilitarised Palestinian state” living side-by-side with Israel in peace and security. While such language is common in diplomatic discourse, it also reflects a deeper tension.

Palestinians have long argued that their right to self-determination includes the right to defend themselves against occupation. Calls for demilitarisation are often seen by critics as reinforcing the status quo, where security concerns are framed almost exclusively in terms of Israeli needs.

In the absence of a genuine political process, some analysts have warned that recognition of this kind risks formalising a state in name only – a fragmented, non-sovereign entity without control over its borders, resources or defence. Without guarantees of territorial continuity, an end to the expansion of Israeli settlements and freedom of movement, statehood may remain an abstract concept.

What would meaningful support look like?

If France wishes to go beyond symbolism, it has options. It could suspend arms exports to Israel or call for an independent international investigation into alleged war crimes. It could use its influence within the EU to push for greater accountability regarding illegal settlements and the blockade of Gaza. It could also support Palestinian institutions directly and engage with Palestinian civil society.

Without such steps, recognition risks being viewed as a political message more than a policy shift. For Palestinians, the daily realities of occupation, displacement and blockade will not change with diplomatic announcements alone. What is needed, many argue, is not just recognition but support for justice, rights and meaningful sovereignty.

France’s recognition of Palestine marks a shift in diplomatic tone and reflects broader unease with the status quo in the Middle East. It has stirred debate at home and abroad, and raised expectations among those hoping for more robust international engagement with the conflict.

Whether this recognition leads to meaningful changes in policy or conditions on the ground remains to be seen. Much will depend on the steps France takes next – both at the United Nations and through its actions on trade, security and aid.

Craft brewer and pub chain BrewDog recently closed some of its pubs in a push to cut operating costs. Given it is partly owned by private equity firm TSG Consumer Partners, the loss-making firm is likely to face further organisational upheaval. After all, private equity firms generally specialise in cutting costs and selling assets.

This downsizing is indicative of the widespread demise of the on-trade beer market (that is, venues that sell beer for consumption on site). The sector is seeing six pubs close down in the UK each week.

It is also testament to the importance of a good finance mix and how this affects a firm’s evolution. Throughout BrewDog’s turbulent history the firm has rarely been out of the headlines, beginning when it launched its in-house equity crowdfunding model.

Labelled Equity for Punks, the scheme enabled non-professional investors to obtain small amounts of equity (that is, shares in BrewDog) in return for relatively small levels of investment (approximately £500). The firm says on its website that the scheme offered beer enthusiasts the chance to “own a slice of the brewery” and offered them “pretty awesome perks” including discounted beer.

From its launch in 2009 until the scheme closed in 2021, Equity for Punks raised £75 million and attracted more than 200,000 small-scale investors. This funding model had major upsides for the firm – generating tremendous growth and expansion over the past 15 years. This vast investment enabled BrewDog to open more than 100 bars and restaurants around the world, employing 3,000 staff.

But how does this funding model work – and who benefits?

First, it enables companies such as BrewDog to access substantial levels of funding from non-professional investors to grow the firm quickly. Second, it cements strong brand loyalty in its investor base. In return for relatively small levels of funding, individual investors obtained promotional benefits – access to new products and company events such as annual shareholder meetings.

Equity crowdfunding models like this are often pursued by growth-orientated, consumer-focused firms that want to expand very quickly. By contrast, most small firms favour more modest levels of growth that are more sustainable in the longer term.

The vast majority of small firms rely on debt finance from banks. But a minority of high-tech firms seek investment from professional investors – business angels (wealthy individuals using their own money) or venture capital (or VC – usually provided by an investment firm). For high-tech firms that want to scale up rapidly, sizeable chunks of VC (£10 million-£40 million) is often the most likely funding route.

The Equity for Punks crowdfunding initiative effectively enabled BrewDog to act like a firm-specific, in-house stock market for small-scale investors. But while some of these investors may have been happy just to support a business they believed in, many will have had little knowledge or experience of equity investment and the risks associated with it.

In essence, this generated easy access to finance for BrewDog, with few strings attached. While venture capitalists and angel investors take an active role in the firms they fund, the equity crowdfunding model offers little active participation for these small-scale investors.

Cautionary tale

As such, the benefits for these investors are less evident. Due to the structure of the subsequent fundraising campaigns, the terms and conditions for investors became less favourable and diluted their original equity stakes in the firm.

Although these small-scale investors still own almost one-third of BrewDog, due to the private nature of the firm the shares cannot easily be traded and they derive very little benefit from their investments. This is especially true while the firm is not making profits.

Unless the firm is acquired, creating demand for the shares, there is little opportunity for the equity punks to realise the value of their original investments in BrewDog. In contrast, under the traditional model of equity investment, VCs and angels would push for strategic measures such as a trade sale of the firm to generate a return on their investment.

The experience of BrewDog is a cautionary one for small-scale equity investors. While hugely beneficial for the recipients of the investment, individual investors might lack knowledge about the true value of their investments.

It is not just BrewDog that has provided small-scale equity investors with little return. In the UK, the main equity crowdfunding platforms have raised substantial capital for young businesses which has produced little return for investors.

Platforms like Crowdcube continue to expand rapidly and raise considerable sums for growth-orientated firms such as BrewDog. However, the benefits for investors are often illusory due to a lack of trade sales known as “exits”, which allow investors to sell their stake.

These platforms are of course legitimate means of raising funds and are regulated by the Financial Conduct Authority.

Some academic research suggests, however, that a lack of due diligence on the part of the platforms can lead to firms with limited track records gaining substantial sums of investment. This can open up the potential for fraudulent behaviour, which economists call the risk of moral hazard.

Investors are not a homogeneous group and have vastly different levels of knowledge surrounding the risks associated with equity investments.

The BrewDog story has become a ubiquitous and commonly used case study by business school academics. Rapid access to vast sums of capital allowed the firm to grow at breakneck speed but with little in the way of stakeholder guidance, supervision and stewardship from investors.

If BrewDog had undertaken more sustainable growth using conventional sources of finance, it’s possible that the firm would be in better shape than it is now. While growth is a policy mantra, the “rollercoaster” nature of rapid growth can entail considerable woes for the entrepreneurs and firms involved.

In a nutshell, small-scale investors were left exposed, with little in the way of concrete returns. For many of them, their beer dreams will have fallen flat. But nonetheless, the growth of equity crowdfunding in recent years has been huge. As such, there’s a case to be made for greater investor protection in this arena.

BrewDog and Crowdcube were approached about the claims made in this article but declined to comment.
