The Lead Levels of some of the most dangerous Pfas compounds have dramatically fallen in Canadian seabird eggs, which the authors of a new peer-reviewed study say illustrates how regulations are effective. The Event Details Researchers looked at Pfas levels in the eggs of northern gannets in the St Lawrence Seaway basin over a 55-year period. Pfas levels shot up from the 1960s through the peak of the chemicals’ use in the late 1990s and early aughts, then fell. The fall coincides with several developments – facing regulatory scrutiny, the chemical giant 3M, which is one of the largest producers of Pfas, began moving away from Pfos, among its most common and toxic compounds. By 2015, major chemical makers reached an agreement with the US Environment Protection Agency to phase out Pfos and Pfoa, the latter a similarly problematic compound. The Data Analysis Data shows the levels of Pfos fell from a peak level in the eggs of 100 parts per billion (ppb) to a level of 26ppb by 2024, a 74% drop. Levels of Pfoa are down about 40% over this time, though they ticked back up in recent years. Meanwhile, PFHxS, another common, toxic Pfas compound fell from 0.69 to 0.19ppb, or about 72%. The Impact Analysis Pfas are a class of at least 16,000 chemicals commonly used to make products resist water, stains and heat. They are called “forever chemicals” because they do not naturally break down, and they are linked to a range of health issues such as cancer, thyroid disease, kidney problems and decreased immunity. Raphael Lavoie, a co-author and ecotoxicologist with Environment and Climate Change Canada, called the findings “good news”. “We see this incredible rise to a peak where concentrations seem to be higher than toxicological threshold for those birds, then it really decreases in a nice way,” Lavoie said. “The regulations are having a good effect.” The Prediction However, it is not all good news. The chemical makers moved to a newer generation of smaller Pfas, and those also present risks to the environment and wildlife. The levels of those compounds have probably grown, and the study found one example of a shift, but the new Pfas are more difficult to measure in bird eggs because they do not accumulate in wildlife as much, Lavoie said. Moreover, compounds such as Pfos stay in the environment or animals’ bodies for decades, so the birds and environment will remain contaminated for the foreseeable future, which the authors wrote “emphasizes the importance of maintaining scientific and regulatory vigilance”.

The LeadUnited States President Donald Trump has rejected Iran's response to his latest peace proposal to end the war, which has upended the global economy. In a series of posts on his Truth Social platform, Trump accused Iran of 'playing games' and called their response 'totally unacceptable,' escalating tensions in the already volatile Middle East region.The Diplomatic BreakdownResponding to the counterproposal Iran sent to the US via mediator Pakistan, Trump wrote that Iran 'has been playing games with the United States, and the rest of the World, for 47 years.' He added: 'They will be laughing no longer!' Two hours later, he reiterated: 'I have just read the response from Iran's so-called 'Representatives'. I don't like it – TOTALLY UNACCEPTABLE!'Iran's Ministry of Foreign Affairs spokesperson, Esmaeil Baghaei, responded by stating that the US continues to have 'unreasonable demands,' adding that Iran's response was 'not excessive.' He emphasized that Iran's proposal to end the war and lift its naval blockade in and around the Strait of Hormuz was a 'legitimate' demand.The Strategic DemandsAccording to Iranian media reports, Tehran countered the US proposal with one of its own, including a demand for an end to the war on all fronts, including in Lebanon, where Israel has carried out heavy strikes and a ground invasion. Iran wants the first stage of negotiations to focus on ending hostilities and ensuring 'maritime security' in the Gulf and the Strait of Hormuz.On the nuclear issue, Iran reportedly proposed to have some of its highly enriched uranium diluted and the rest transferred to a third country. They were also willing to suspend enrichment for a shorter period than the 20-year moratorium proposed by the US but rejected dismantling nuclear facilities.In contrast, the US has demanded that Iran reduce uranium enrichment to 0% and hand over its estimated 440kg stock of enriched uranium. The US 14-point peace proposal also requires Iran to agree not to develop a nuclear weapon and to halt all enrichment for at least 12 years.The Regional ImplicationsThe ongoing tensions have significant implications for global energy markets, as the Strait of Hormuz is through which one-fifth of global oil and natural gas exports are shipped during peacetime. Iran's de facto blockade of the strait came in response to US and Israeli attacks on the country on February 28.The naval standoff has disrupted international shipping, with both the US and Iran continuing to attack, capture and intercept ships. Countries in the Gulf region have also come under attack again, threatening regional stability and security.Chris Featherstone, a political scientist at the University of York, noted that Iran has not conceded to US demands, which appears to have confounded Trump. 'The Iranians are maintaining their conditions for a long-term peace deal,' he said, adding that Trump has 'painted himself into a corner' in these negotiations.The Path ForwardWith neither side agreeing to a peace deal, experts suggest limited options for Trump. Ali Vaez, director of the Iran Project at the International Crisis Group, stated that 'no amount of economic coercion or military force will compel Iran to capitulate to maximalist US demands.' Trump is left with what Vaez calls 'two bad options: escalate a war he cannot win, or accept a compromise he cannot sell.'Mark Pfeifle, a former US national security adviser, suggested that Trump is unlikely to resume the war but may ramp up economic pressure through the blockade and conduct limited military actions targeting Iran's fast boats, drone launch pads and missile sites. Trump could also tighten sanctions or push for European and Asian naval forces to help escort ships through the Strait of Hormuz.As Baghaei stated, 'Whenever we are forced to fight, we will fight, and whenever there is room for diplomacy, we will seize that opportunity.' However, with both sides entrenched in their positions, the path to a comprehensive peace agreement remains uncertain.

The Nocturnal Visitors A big moon is cresting the Scots pine as I sit at an upstairs window looking down on to the garden. Awaiting the dusk emergence of a female tawny owl has become an evening ritual. After a day spent in the confines of a nest box in our sycamore tree, her departure shifts back by a few minutes every night. Completely silent, she drops towards the woodland border and skims the plants, each time on the same trajectory, a grey shadow in the gloaming. Secretive Woodcock Another movement on the path below catches my eye: a woodcock slinking along, using the box hedge to disguise her passage. If I hadn’t been watching for the owl I would never have known that she too is nesting somewhere in the garden’s thick leafiness. In July 2023, I wrote about a woodcock nesting in a flower border a few metres from the house, four chicks successfully hatching from four eggs. Last year, another attempt was disturbed by a cat captured on trailcam. This may be the same bird returned for a third time. Woodcocks are extremely secretive birds, their close proximity to a house very unusual. The Mallard's Close Call A third nest this year is that of a mallard, hidden beneath foliage just inches from a path. I talked to her as I walked by so she was familiar with my voice, since I knew I’d have to help her get the ducklings over the boundary wall. When they hatched, I was ready with a bucket. She was unflustered as I approached her and scooped all 10 ducklings into the bucket. Then I held it, squeaking and piping, over the wall. The mallard flew over, rejoined them and led them to the river. The Human Shield Effect The “human shield effect” changes the behaviour of animals, making them less vigilant for predators when they know that humans are around. Unwittingly through our presence, combined with the undisturbed density of this wildlife garden, we have made birds feel safer here, and maybe they have learned this from successful previous years. A Nocturnal Reunion Early evening, the female tawny gets restless and calls to the answering male. He flies briefly to the nest box for a noisy reunion, before remerging in front of us, wing tips backlit by amber sunlight.

The Leadership Challenge Ahead United Kingdom Prime Minister Keir Starmer is likely to face a leadership challenge amid calls from parliamentarians for him to step down following the Labour Party's stunning loss in local elections. Calls for Starmer's Resignation Backbencher Labour MP Catherine West urged cabinet ministers to 'move quickly' to replace him, saying she planned to email her colleagues for the necessary support on Monday morning if no one else put themselves forward. More than 30 Labour MPs have said Starmer should resign or set out timetables for his departure. His former ally Josh Simons wrote in The Times that Starmer had 'lost the country'. The Election Results Last week's elections saw Labour lose almost 1,500 councillors in England, largely to Reform UK and the Greens. In Wales, First Minister Eluned Morgan lost her seat, ending the party's 27 years in power there. In Scotland, the Scottish National Party retained its position, with Labour coming second. Support and Criticism Others remain supportive of the prime minister, including Education Secretary Bridget Phillipson, who told Sky News that she did not believe 'a leadership contest and all of the problems that that would bring is the answer'. Starmer is set to give a speech on Monday, along with the king's speech on Wednesday, that will attempt to convince the public and his party of his leadership. Future Outlook A leadership contest requires the endorsement of 81 Labour MPs. Likely challengers to the leadership include Health Secretary Wes Streeting, former Deputy Prime Minister Angela Rayner and Greater Manchester Mayor Andy Burnham. Starmer's government has been in power since 2024, when it ended 14 years of Conservative rule in a landslide victory. His popularity has since fallen, with the decision to cut the winter fuel allowance amid a cost-of-living crisis and the scandal over United States Ambassador Peter Mendelson's links to sex offender Jeffrey Epstein contributing to this decline.

The Horror Crash That Ended Jay Vine's Giro d'ItaliaAustralian cycling star Jay Vine has suffered a broken elbow and concussion in a horror crash during the Giro d'Italia, forcing him to abandon the race. The UAE Team Emirates rider, who has endured 23 spills in his five-year career, was fortunate to avoid more serious injuries according to his team and wife.Details of the High-Speed CrashThe 30-year-old Vine was involved in a third serious crash in just 13 days of racing when he was brought down by teammate Marc Soler's slipping front wheel with 22km remaining in Saturday's stage. The high-speed crash occurred on a soaking right-hand turn, causing multiple riders to career into a roadside barrier."Unfortunately, we were badly affected by the crash on stage two yesterday," Dr Adrian Rotunno, UAE Team Emirates' medical director, said. "Jay Vine suffered a concussion and an elbow fracture. Marc Soler has a pelvic fracture. At this stage, neither should require surgery."Team leader Adam Yates also abandoned the race after suffering heavy abrasions and a laceration to his left ear, with delayed concussive symptoms appearing after initial clearance.Team Devastated but RelievedUAE Team Emirates, considered the peloton's most powerful outfit, was left decimated by the crash with three of their key members forced to abandon the race. The team expressed relief that the injuries, while serious, were not more life-threatening."Yesterday was honestly really scary," Bre Vine, Jay's wife, wrote on Instagram. "But the main thing is Jay is OK. Considering how bad that crash was, he's been relatively lucky to come away without anything more serious.""Unfortunately in this sport you can do everything right, be in the right position, and still end up on the ground," she added, highlighting the unpredictable dangers of professional cycling.Implications for the Giro d'ItaliaThe crash has significantly weakened one of the pre-race favorites for the overall classification. With Vine, Soler, and Yates all out of contention, UAE Team Emirates faces an uphill battle in the remaining stages of the race.The Giro arrives at its Italian home on Tuesday, following Monday's rest day, with stage four's 138-km ride from Catanzaro to Cosenza. The absence of three key riders from one of the strongest teams will undoubtedly affect the dynamics of the race.Recovery Road Ahead for VineDespite the severity of his injuries, Vine faces a positive recovery prognosis as he will not require surgery. The Australian will now focus on rehabilitation as he travels home to continue his recovery under medical supervision.This latest crash adds another chapter to Vine's accident-filled career, which has seen him endure 23 spills in his five years as a professional cyclist. His resilience will be tested as he works to return to competitive form following this latest setback.

The Lead: Trump's Fragile Position in Beijing Like an out-of-control wrecking ball, swinging wildly back and forth, Donald Trump smashes up the international order without much thought for the consequences. Lacking coherent strategies, workable plans or consistent aims, he power-trips erratically from one fragile region, tense warzone and complex geopolitical situation to another, leaving misery, confusion and rubble in his wake. The president will bulldoze into another international minefield this week – the fraught standoff between China and Taiwan – when he travels to Beijing for a two-day summit with President Xi Jinping. The Geopolitical Chess Game: Trump's Desperate Need for Xi's Help After a string of humiliating policy implosions over Ukraine, Gaza, Nato, Greenland, and now Iran and Lebanon, needy Trump craves a diplomatic success to flaunt at home. But his hopes of vote-winning trade pacts are overshadowed by his latest war of choice. He needs Xi's promise not to arm Iran if all-out fighting resumes – and Xi's help keeping the strait of Hormuz open as part of a mooted framework peace deal. The weakness of Trump's position going into the summit is fuelling speculation that reduced US support for Taiwan may be Xi's price for playing nice. The Power Dynamics: How Trump's Failures Strengthen Xi's Position Xi knows the Iran war is deeply unpopular with US voters. Trump is universally blamed for pushing up global energy, food and medicine prices. European allies have refused to bail him out, Russia is undeservedly benefiting from inflated oil prices – and poorer countries bear the brunt. Trump is not winning militarily, either, as shown by his half-baked, on-off Project Freedom. For China, Trump is the gift that keeps on giving. Thanks to him, the US is increasingly viewed internationally as an aggressive potential enemy or unreliable friend, much given over to treachery. The Taiwan Factor: Xi's Ultimate Priority Xi's top external priority is not the Middle East. It is the unification of communist China with a de facto independent, democratic Taiwan – a personal legacy project that he has repeatedly threatened to pursue by force. Pentagon planners believe China's ever-expanding military could be ready to launch an invasion next year. Taiwan's forces are vastly outnumbered, while its fractious political parties are as divided as ever about increased defense spending and the wisdom or not of seeking closer ties with Beijing. The Iran Conflict: A Double-Edged Sword for China The downside for Xi is the negative impact of the war on energy prices, global trade and export demand at a time when China's economy is already struggling. Last year, about 80% of Iranian oil shipments were bought by China – shipments the US navy is now blocking. So far, Beijing has largely managed to offset supply shortfalls from the Gulf by drawing on reserves, capitalising on green energy and buying more oil from countries such as Brazil and Russia. But for the world's largest importer of crude oil, safe and reliable navigation through the strait of Hormuz is critical. The Strategic Implications: US Military Resources Diverted from Asia The Iran impasse is drawing US forces away from Asia – it now has two aircraft carrier strike groups in the Middle East – and reducing its military capacity to defend Taiwan and regional allies from future Chinese aggression. China is urging both sides to embrace a negotiated settlement. It hosted direct talks last week with Iran's foreign minister, Abbas Araghchi, and is backing Pakistani intermediaries. Recalling China's successful 2023 fence-mending between Saudi Arabia and Tehran, anxious Gulf states are counting, like Trump, on Beijing's ability to influence its Iranian ally. The Future Outlook: A Potential Taiwan Compromise? Trump seems aware of this risk. He wrote to Xi last month, asking him not to supply weaponry to Tehran – and said he had received assurances China would not do so. But the Foundation for Defense of Democracies, a conservative US research institute, claims China already provides Iran with dual-use precursor chemicals for its ballistic missiles, satellite intelligence about US military movements, assets and bases, and help with sanctions evasion and money laundering. For a man who likes to boast he holds all the cards, the US president may find himself seriously short of trumps when he sits down with Xi.

The Genesis of a Masterpiece This week we mark two extraordinary centenaries. Sir David Attenborough's, of course, but only four days after the birth of the bona fide national treasure, Dmitri Shostakovich's First Symphony also first saw the light of day – premiered in Leningrad on 12 May 1926. The 19-year-old's composition was played by the Leningrad Philharmonic, conducted by Nicolai Malko. The Revolutionary Sound The symphony's four-movement structure is just about the only conventional feature it has. The teenage Shostakovich had imbibed all the lessons he could about what orchestral music should sound like and how it should behave, and was bold enough to subvert all those ideas and send them up. There is no forelock-tugging to earlier generations of Russian symphonists and orchestral pioneers; instead, Shostakovich's First resounds with a self-confidence that's both optimistic and deliciously sardonic. A Circus of Sound From the distorted trumpet call that opens the work – a fanfare that thumbs its nose at your expectations of how a symphony should start; not an affirmative flourish, but a snakingly dissonant question mark – Shostakovich sets out on a first movement that's like a circus: a cavalcade of characters who take the stage and exit, more often than not pursued by a cartoon bear, clown or bassoon. The momentum that Shostakovich generates from the way he juxtaposes ideas – cutting from one to the other as if the symphony were a reel of film – continues deliriously in the second movement. Here, a piano part is added to the orchestral texture, and that's where one of the secrets of this music's compositional energy is revealed. As a teenager, Shostakovich played the piano for Soviet silent cinema screenings, and in the symphony's piano solos, he turns his work into a knockabout farce that Buster Keaton would be proud of. A Masterpiece of Unbridled Creativity The movement builds to a climax that is both terrifying – a sudden fanfare that consumes the whole orchestra – and bathetic, in the form of the solo piano's chords, as if the pianist couldn't keep up with the music's pace. There is no hint anywhere in this piece of the bombast and poster-paint ideology of Shostakovich's later symphonies, but there is real feeling here, hinted at in that climax of the scherzo, as the cartoon suddenly shudders into real life. The slow movement that comes next is one of the most unironically passionate that Shostakovich ever wrote, as a solo oboe and solo cello inspire the whole orchestra to a melodic outpouring that feels more Shakespearean drama than circus hijinks. A Legacy of Creative Freedom The final movement somehow brings all of these worlds together, and the symphony ends in a torrent of irresistible energy, a culmination of pure sentiment as well as sheer excitement. This is, surely, the most creatively confident First Symphony by any teenager in musical history (and there is plenty of competition, from Mendelssohn to Knussen, from Rihm to Schubert). It announces a world of possibility in which musical conventions are gleefully turned upside down in a frenzy of modernist creativity that's both funny and profound. It's the sound of a unique symphonic avant garde that might have heralded an era of unfettered creative freedom for Shostakovich and generations of composers. A What-If of History Instead, these are the sounds of what might have been, for Shostakovich and for Russia. In Shostakovich's later symphonies, especially from the mid-1930s onwards, you hear the chilling of that freedom and the daily terror of living in Stalin's Soviet Union. The confidence and joy in his own brilliance that you hear in every page of the First Symphony is a miracle that Shostakovich never quite repeated and which is still strikingly new, a century on.

The Lead: Perry's Raw Return to Center Stage Linda Perry, the iconic singer-songwriter behind 4 Non Blondes and hitmaker for stars like Christina Aguilera and Pink, is stepping back into the spotlight after years working behind the scenes. Her new documentary "Linda Perry: Let It Die Here" and accompanying album capture her journey through breast cancer, the death of her abusive mother, and her complex emotional landscape as she reclaims her artistic identity. The Event Details: Cancer, Loss, and Creative Resilience The documentary, directed by Don Hardy who had been filming Perry at work, captures her just over a week after a double mastectomy, walking gingerly into her studio while carrying surgical drains she calls "blood grenades." As Perry recovered from surgery, her elderly mother—who had physically and mentally abused her as a child—became ill and died three months later. Perry took her mother into her home for her final months, setting up a bed next to hers, reflecting that "the best gift my mom gave me was a peaceful death." The Creative Process: From Personal Pain to Artistic Expression Perry's new solo album, her first in 27 years, is a visceral, propulsive work about her mother's death and the complex feelings it unearthed. Songs include "I Am Daughter," "Now That She's Gone," "Liberation," and "What Lies With You," in which she calls her mother "the villain and the muse." The documentary shows Perry's songwriting prowess in action as she jams with Dolly Parton and Kate Hudson, while also capturing her hosting an event at South By Southwest for EqualizeHer, an organization she co-founded to promote gender equality in the music industry. The Industry Impact: A Voice for Gender Equality Perry has long been an advocate for gender equity in music. Early in her career, she was famously denied a producer credit on "What's Up," the track that sent 4 Non Blondes stratospheric. She let it go at the time but vowed it would never happen again. Through EqualizeHer and her own experiences, Perry continues to challenge the industry's gender disparities. The documentary also captures her re-formed 4 Non Blondes performing at the BottleRock festival, where she insisted on performing new material rather than just their old hits, stating "I want to play something new." The Personal Journey: Confronting Trauma and Finding Strength The documentary offers intimate glimpses into Perry's personal struggles, including a scene where she's captured dancing goofily in her closet to Supertramp's "Take the Long Way Home," which triggers deep emotional release. Another powerful moment shows her ripping open her shirt during a photoshoot in the desert to reveal her surgical scars, describing it as "ad-lib, a kind of a 'fuck-it' moment" that felt powerful afterward. Perry admits she's a workaholic who finds safety in creating: "Like most people who are in trauma, I am afraid to be left alone. Creating, working and music is where I feel safe." The Future Outlook: New Music and Continued Advocacy Perry's re-formed 4 Non Blondes are working on a new album due out early next year, based on material she wrote specifically for festival performances. She continues to collaborate with other artists, including Paris Jackson and Mike Campbell of Tom Petty's Heartbreakers. While the documentary was difficult for Perry to watch—"It was like watching a horror movie"—she recognizes its therapeutic value: "I think maybe the film helped me process and see something I didn't know I was doing." As she walks into the distance at the end of the documentary, Perry reflects: "Everything I've just experienced is going to change my life drastically. Life and death happened just now, so let's see what happens from here."

The Accusation Against Rebel Wilson Rebel Wilson has been accused in court of being a liar who made up terrible claims about her colleagues and completely rewrote history. The Pitch Perfect star copped the blunt assessment in the dying hours of a fiery defamation battle where she is being sued by Charlotte MacInnes, the lead actor in musical comedy The Deb which Wilson directed, co-produced and starred in. The Defamation Claims MacInnes claims Wilson defamed her in a series of social media posts that suggested she is a liar and a sellout who walked back a sexual misconduct complaint to further her career. The posts claimed MacInnes confided to the older actor – and later recanted – she felt uncomfortable when the film’s co-producer Amanda Ghost asked to have a shower and a bath together. The Inconsistencies in Wilson's Evidence MacInnes’ barrister Sue Chrysanthou SC accused Wilson of a “complete revision of history” littered with dishonesty during her emphatic closing address in the Federal Court on Friday. She noted the Bridesmaids actor testified she told local producer Greer Simpkin about the alleged complaint on the day it was made to her, but that had been contradicted in court. Simpkin gave evidence she had not heard that Wilson claimed her co-star felt uncomfortable about the incident until it was relayed by Ghost a week later. Wilson's own witnesses have discredited her, Chrysanthou told the court. The Impact on MacInnes MacInnes has suffered devastating harm as a result of the social media posts and hasn’t worked since she starred in a stage production – a role which she had previously secured, her barrister said. “My client has been unable to eat, unable to sleep, has been distressed … (she) fears what Rebel Wilson is going to do to her next,” Chrysanthou said. “No young woman dreams of being pulled into the spotlight by a celebrity and maligned”. Wilson's Response But Wilson testified the young star doesn’t appear to have sustained any damage to her reputation or career, pointing to the lead role and a six-figure record deal MacInnes has secured. “She’s changed her story, she’s flip-flopped and she’s been given huge benefits,” she said.
