The United States Supreme Court issued an 8‑1 decision on Tuesday that invalidated Colorado’s law prohibiting “conversion therapy” for LGBTQ minors. The majority held that the ban infringed on the First Amendment’s free‑speech guarantees, arguing that even therapeutic dialogue falls under protected expression. Justice Elena Kagan wrote that when a state suppresses one side of a debate while supporting the other, the constitutional issue is “straightforward.” In contrast, Justice Neil Gorsuch emphasized that the First Amendment “stands as a shield against any effort to enforce orthodoxy in thought or speech.” Only Justice Ketanji Brown Jackson dissented, warning that the ruling “threatens to impair states’ ability to regulate the provision of medical care” and underscored the documented harms of conversion therapy to LGBTQ youth. Colorado’s 2019 statute barred any “practice or treatment” aimed at changing a child’s gender identity or sexual orientation, though it allowed discussion of religion, gender, and sexuality. No individual has yet been sanctioned under the law. The case was brought by Christian counselor Kaley Chiles, who argued that the ban prevented her from offering voluntary, faith‑based talk therapy, a position backed by the administration of former President Donald Trump. Approximately two dozen states have enacted similar bans, reflecting a growing consensus that conversion therapy is both ineffective and harmful. Scientific studies link the practice to higher rates of depression and suicidal ideation among LGBTQ individuals. Major medical associations have condemned it as a dangerous, discredited intervention. Advocates for LGBTQ rights criticized the Court’s ruling as a setback. Polly Crozier, director of family policy at GLAD Law, said, “This is a dangerous practice that has been condemned by every major medical association in the country. Today’s decision does not change the science, and it does not change the fact that conversion therapists who harm patients will still face legal consequences.” The decision is expected to make enforcement of existing bans more difficult, potentially prompting a wave of legal challenges in other jurisdictions that have sought to protect LGBTQ youth from conversion therapy.

Aarti Holla-Maini, a British lawyer with a background in the satellite business, is the director of the UN's Office for Outer Space Affairs (Unoosa). She is responsible for alerting the UN secretary general if a large asteroid is on a possible collision course with Earth.On 27 December 2024, a robotic telescope in Chile spotted a distant rock, asteroid 2024 YR4, which was initially estimated to be the size of a small building. As the asteroid's impact probability increased, Holla-Maini's team drafted a letter to the UN secretary general, triggering the first global notification since the UN established a planetary defence collaboration in 2013.The asteroid's size and speed meant an impact could release energy comparable to hundreds of times the power of the Hiroshima bomb, potentially wiping out a city or region. The asteroid reached level three on the Torino Impact Hazard Scale, indicating a threat to human civilization.Holla-Maini's team worked with the International Asteroid Warning Network and other experts to track the asteroid. Although its impact probability peaked at more than 3% in February 2025, it has since dropped to a negligible level. The asteroid scare served as a useful test for Unoosa's role in planetary defence.Unoosa plays a critical role in registering satellites launched into Earth's orbit and acts as an informal 'hotline' for potential satellite collisions. Holla-Maini's small team of 35 employees punches well above its weight, managing a massive remit as governments and businesses increasingly operate in space.

More than 250 players from the southern hemisphere are now integral to European rugby, fundamentally shaping the landscape of top-flight competitions across France, Scotland, England, Italy, Ireland and Wales. These athletes, drawn from 12 nations including Chile, Zimbabwe and the Cook Islands, have been drawn north by the gravitational pull of financial security and career opportunities, with over 60 hailing from South Africa and 56 from Argentina.Their presence has transformed European rugby, both in terms of quality and the development of local players who compete alongside and against them. This southern exodus continues despite the cultural and rugby significance of these nations, creating a complex dynamic where talent flows north while the sport's soul remains rooted in the south.Fiji exemplifies this tension. While 31 Fijian players currently compete in Europe, the Fijian Drua, with 40 players on their books, recently demonstrated the passion and potential of homegrown talent by defeating the ACT Brumbies 42-27 in front of 10,000 fans in Ba. The match, played despite challenging conditions including a previously flooded pitch, showcased rugby's authentic connection with its supporters.However, this authentic expression of rugby faces an uphill battle against commercial realities. When the Nations Championship brings hemispheres together later this year, Fiji's "home" fixtures will be staged offshore – against Scotland in Edinburgh, England in Liverpool and Wales in Cardiff. Despite Fiji Rugby Union chief executive Koli Sewabu's determination to "make it feel every bit like a home game," the relocation speaks to larger priorities.The financial imperative extends beyond Fiji. At a recent World Rugby meeting, representatives from New Zealand and Australia pushed for greater tempo and less emphasis on set-piece power, only to be blocked by France and South Africa, who possess the most intimidating packs. This diminished influence reflects a broader shift in power dynamics.South Africa, despite exporting more talent to Europe than any other nation and winning four World Cups, faces significant constraints. SA Rugby's chief executive, Rian Oberholzer, acknowledged that neither South Africa nor New Zealand are presently viable World Cup hosts because they "do not generate the revenue World Rugby requires." The Rugby World Cup, he explained, "is the only revenue stream for World Rugby that must fund the whole ecosystem."Argentina faces similar challenges. The Pumas, despite being a formidable international side, struggle to host major tournaments due to the absence of a professional domestic league and the fact that all but three of their most recent squad members play in Europe.This creates a fundamental tension in modern rugby: the sport's most compelling talent and authentic experiences emerge from the southern hemisphere, yet financial decisions increasingly favor northern markets. While rugby needs these financial resources to fund competitions and maintain grassroots development, the balance between authentic connection and commercial imperatives will ultimately determine the game's future trajectory.

A recent study published in the European Journal of Preventive Cardiology has revealed that small changes to daily habits can have a significant impact on cardiovascular health. The research, conducted by experts from Australia, Chile, and Brazil, examined data on more than 53,000 middle-aged UK adults taking part in the Biobank study.The study found that sleeping for 11 minutes more each night, doing 4.5 additional minutes of brisk walking, and eating an extra 50g of vegetables each day can reduce the risk of major cardiovascular events, including heart attacks and strokes, by about 10%. These small behavior changes were found to be more "achievable and sustainable" compared to attempting major changes in a single behavior.According to the study, the "optimal" way to avoid cardiovascular incidents includes getting eight to nine hours of sleep each night, a good diet, and a minimum of 42 minutes of moderate-to-vigorous physical activity each day. Combining these measures leads to a 57% lower risk of heart attacks and strokes.Dr. Nicholas Koemel, the study's lead author, noted that "making a few small, combined changes is likely more achievable and sustainable for most people when compared with attempting major changes in a single behavior." He encouraged people to make small changes to their daily routine, as they can have a surprisingly large positive impact on cardiovascular health.Prof Emmanuel Stamatakis, a senior author of the study, plans to build on these findings to develop new digital tools that support people in making positive lifestyle changes and establishing sustained healthy habits.Commenting on the study, Emily McGrath, a senior cardiac nurse at the British Heart Foundation, said that "small tweaks – like getting a little more sleep, adding a few extra minutes of activity to your day or eating a bit more veg – can work together to have a meaningful positive impact on your heart health."

Six decades ago, pioneering oceanographer and conservationist Sylvia Earle made a remarkable discovery while diving off Chile’s oceanic islands. She found the remains of a baby fur seal, a species endemic to the Juan Fernández archipelago that was believed to have been hunted to extinction in the 19th century. This discovery gave Earle hope that a small population might still exist, and indeed, a year later, a colony of 20 endemic fur seals was confirmed on Robinson Crusoe Island.Today, after decades of conservation efforts, the fur seal population has made an extraordinary recovery. An estimated 200,000 fur seals now inhabit the waters around the islands, returning them to their previous role as key members of the ecosystem. Earle, now 90, who returned to the island to dive in December 2025, described the archipelago as a critical 'Hope Spot' for marine protection.In a significant conservation victory, outgoing Chilean President Gabriel Boric recently signed an agreement to extend protection of 337,000 sq km of waters around Juan Fernández and the nearby Nazca-Desventuradas marine park. Once implemented, this 'no take' zone will extend to almost 1 million sq km, making it the third-largest such marine protected zone in the world. By doing so, Chile would protect more than 50% of its waters, placing it in a rare category alongside countries such as Panama and French Polynesia.The protection prohibits all fishing activities except within 12km of the coast, allowing the community of approximately 1,000 lobster fishers to continue their traditional livelihood. Chile is now out in front globally in ocean protection efforts, according to Earle, as most countries have been slower to commit to such extensive marine conservation.The initiative was driven by the Juan Fernández islanders and conservation NGOs who have advocated for decades to protect the unique ecosystem. The fishers, who witnessed the damage caused by industrial fishing of the orange roughy in the 1990s and 2000s, have practiced stewardship of their fishery. A survey showed 98% of residents supported extended protections, leading the fishers to present a proposal directly to the president.Julio Chamorro Solís, a lobster fisher and president of the local fishing organization, emphasized the importance of the unique ecosystem: 'We know the level of endemism we have and how fragile this ecosystem is. There's a biological treasure here.'However, the future of this expanded protection remains uncertain. The new Chilean government, led by President-elect José Antonio Kast, is currently reviewing environmental laws established by the previous administration. While the Chilean ministry of the environment has stated its intention is not to eliminate protections, conservationists and islanders await confirmation that the marine park extension will proceed as planned.This initiative aligns with global commitments to protect 30% of the world's oceans by 2030, a goal reinforced by the recent implementation of the high seas treaty. The expansion of Chile's marine protected areas represents a significant step toward achieving this ambitious target while safeguarding one of the planet's unique marine ecosystems.

Have you ever felt like you're racing against the clock, constantly chasing appointments and deadlines? This relentless pursuit of time is a universal experience, but what is time, really? Is it a physical phenomenon or just a tool we use to coordinate our lives? Time is often seen as an independent, physical entity that ticks by relentlessly, but emerging scientific evidence suggests that this isn't the case. Time is more like a mathematical tool, useful for coordinating our interactions, but it doesn't have an independent existence of its own. Just like money, we've become dependent on it, but it's not a physical reality. The pressure to be 'on time' is instilled in us from a young age, and we're constantly surrounded by clocks and digital alerts that divide our day into smaller pieces. This has led to a phenomenon known as 'time famine,' where the more efficient and productive we try to be, the less time we feel we have. Studies have shown that people experiencing time famine are less likely to engage in activities they enjoy, eat healthily, or seek medical attention when needed. Our brains don't have dedicated areas for tracking time, and our experience of it can vary greatly. Time can seem to drag or fly by, depending on our circumstances. For example, people with certain conditions, like akinetopsia, experience time in sudden jumps or frozen moments. The psychedelic drug mescaline can also distort time perception, making it seem like hours or even centuries have passed. Quantum physicists have found that time is not a fixed, physical flow. The famous double-slit experiment shows that a physicist's choice of measurement can influence the behavior of a particle. In a lesser-known variant of this experiment, the physicist's choice at the point of measurement can even influence the particle's past behavior. This suggests that time is not a fixed, linear concept, but rather a flexible and subjective experience. Some indigenous cultures, like the Aymara people of Chile, experience time differently. They see the future as hidden behind them, unseeable and unknowable. The Amondawa people of the Amazon have no clocks or concept of time. Instead, they live in the present, experiencing 'lived time,' which is a personal, malleable experience of change. Lived time is different from clock time, as it's not defined by numerical counters or seconds. Each moment is like a tapestry, woven from changes on multiple timescales. When we focus on lived time, it expands and becomes richer, rather than narrowing or contracting. It's a flow that carries us and connects us with others, rather than something we chase and never catch. To combat time famine, we need to remind ourselves that the clock is a tool, not a master. We should beware of digital alerts and alarms that divide our day into smaller pieces and instead focus on the rich pattern of changing connections that wire us into each moment. By doing so, we can tap into the creative process of lived time and experience a more fulfilling and connected life.
