New research indicates that individuals carrying the red‑hair allele have been evolutionary winners in Europe for more than 10,000 years. The study, led by Harvard scientists, examined DNA from nearly 16,000 ancient remains and over 6,000 living Europeans, providing robust proof that human biology continues to evolve long after farming began. Researchers identified 479 genetic variants that show clear signs of positive selection. Among these are genes linked to red hair and fair skin, as well as variants that affect susceptibility to coeliac disease, diabetes risk, baldness and rheumatoid arthritis. The authors suggest that the advantage of red hair may stem from its association with lighter skin, which enhances vitamin D synthesis in low‑sunlight environments—a crucial benefit for early European farmers. Prior to this work, only about 21 traits had been documented as having risen through natural selection, such as lactase persistence. The scarcity of earlier examples had led some to argue that directional selection was rare after modern humans left Africa. By leveraging an unprecedented volume of ancient genomic data and advanced computational methods, the team demonstrated that selection pressures intensified during the transition from hunter‑gatherer societies to agricultural ones, reshaping hundreds of genes across West Eurasia. "With these new techniques and the sheer scale of ancient DNA, we can now observe how selection sculpted our biology in near real‑time," said Dr. Ali Akbari, the study’s first author. Beyond vitamin D, the rise of certain disease‑related alleles poses intriguing puzzles. A mutation that heightens the risk of coeliac disease emerged around 4,000 years ago and has steadily increased, implying that carriers may have enjoyed other survival advantages despite the autoimmune threat. Similarly, the immune‑regulating gene TYK2, which markedly raises tuberculosis susceptibility, grew in frequency between 9,000 and 3,000 years ago before declining, hinting at a complex balance between pathogen defense and disease risk. The analysis also uncovered negative selection against genetic profiles that promote a high body‑fat percentage, supporting the classic “thrifty genes” hypothesis: traits advantageous for storing energy during scarce hunter‑gatherer periods became detrimental once agriculture ensured a steadier food supply. "This work lets us assign both place and time to the forces that have shaped us," noted Prof. David Reich, senior author and Harvard Medical School geneticist. While the findings are confined to West Eurasian populations, they raise broader questions about whether similar evolutionary dynamics occurred elsewhere. The full study appears in Nature.

Crystal Palace turned a daunting 3‑0 first‑leg deficit into a triumphant advance after fending off a determined Fiorentina side in the second leg of the UEFA Europa Conference League quarter‑final. The match began with Ismaïla Sarr opening the scoring early, giving the South London fans a glimmer of hope. Despite losing Adam Wharton and Maxence Lacroix to injuries before the break, Palace maintained composure and kept Fiorentina at bay. Fiorentina, managed by Paolo Vanoli, reduced the aggregate gap to two goals with about thirty minutes remaining, sparking a tense period. However, Palace’s defence, anchored by David de Gea in goal, held firm, denying further breakthroughs. Key moments included a penalty conversion by Albert Gudmundsson and a crucial save from de Gea after a wayward strike by Daniel Muñoz. Palace also benefited from a disciplined performance by goalkeeper Dean Henderson, who thwarted several Fiorentina attempts, including a long‑range effort from Cher Ndour. In the second half, manager Oliver Glasner introduced Norwegian striker Jørgen Strand Larsen, who replaced Jean‑Philippe Mateta, adding fresh impetus to the attack. Although Fiorentina pressed hard, Palace’s makeshift defence weathered the storm, and a late header from Roberto Piccoli sailed over the crossbar, sealing the result. With the aggregate score favoring Palace, the club now prepares for a semi‑final clash against Shakhtar Donetsk, marking a remarkable milestone for a side that, just a year ago, was still awaiting its first major trophy. Fans celebrated the achievement under the Tuscan sun, with vibrant displays of red and blue flags and flares organized by the Holmesdale Fanatics, highlighting the growing passion surrounding Palace’s European adventure.

Iran has deployed small surface vessels to lay mines in parts of the Strait of Hormuz, a critical waterway for global shipping. The exact number of mines laid is unknown, but Iran has left a path open to ships that are prepared to pay a toll.According to US officials, Iran has indicated that it cannot locate all of the mines that it has laid and lacks the capability to remove them. The mines are part of an array of offensive options available to Iran in the strait, including cheap drones, anti-ship missiles, and fast-attack small vessels.Iran is thought to have deployed two main types of mine: the Maham 3 and the Maham 7. The Maham 3 is an anchored, 300kg mine that can be used in waters as deep as 100 meters, while the Maham 7 is a bottom-resting 220kg mine for use in shallower waters.The US plans to use uncrewed marine mine-hunting vehicles, such as the Knifefish undersea mine hunter, to clear the mines. The US could also deploy the AN/ASQ-235 (Archerfish) airborne mine neutralization system from an MH 60S helicopter.The global economy's reliance on maritime trade gives countries deploying mines an outsized leverage compared with the relatively low cost of laying the mines. It takes only a small number of mines to close sea lanes, not least because some mines can be set to detonate after a certain number of ships have passed over, creating uncertainty.

Prime Minister Keir Starmer convened senior leaders from Meta, TikTok, Google and X at No 10 on Thursday to discuss the escalating child‑safety crisis on social platforms. He told the executives that "things can’t go on like this" and that immediate reforms are essential to protect minors. The meeting comes as the UK government launches a formal consultation on imposing a firm age limit for social‑media users, echoing Australia’s recent ban for under‑16s. The proposal also examines curbing design features such as infinite scrolling that encourage prolonged use. Starmer emphasized that restricting access for younger users is preferable to allowing ongoing harm, stating that a future where children are shielded—even at the cost of reduced participation—is the goal. He added that the challenge lies not in the decision to act, but in determining the most effective implementation strategy. While the prime minister has previously cautioned that a blanket ban could push teenagers toward the dark web, pressure from within his own party has intensified. More than 60 Labour backbenchers recently signed a letter urging a ban, and many expect Starmer to endorse the measure once the consultation concludes this summer. Parliament’s recent actions illustrate the split view: MPs rejected a House of Lords amendment that would have introduced an automatic age gate, preferring to await the government’s response to the consultation. A separate Conservative‑led amendment proposing a twelve‑month trial of platform bans was also defeated in the Commons. Early education minister Olivia Bailey defended the consultation approach, arguing it allows a broader assessment of services and features than the narrow amendment proposed in the Lords. The government is also pressing Ofcom, the communications regulator tasked with enforcing the Online Safety Act, to act decisively. Last year, technology secretary Liz Kendall warned that Ofcom risked losing public trust if it failed to curb online harms. This month she appointed former Channel 4 chair Ian Cheshire as the new Ofcom chair to steer the regulator through this critical period. Google declined to comment on the No 10 meeting, while Meta, TikTok and X have been approached for responses.

A Pakistani delegation headed by Army Chief General Asim Munir arrived in Tehran on Wednesday, bearing a fresh message from Washington and urging the launch of a second round of negotiations between the United States and Iran. The effort comes as the two‑week ceasefire that halted hostilities last week is set to expire on April 22, leaving a narrow window to end a war that has claimed more than 4,000 lives across the Middle East, primarily in Iran and Lebanon. The initial round of talks, held in Islamabad on April 11‑12, marked the most significant direct engagement between Washington and Tehran in decades. Mediated by Pakistan, the sessions lasted over 20 hours and featured both indirect and direct exchanges between U.S. Vice President JD Vance and senior Iranian officials led by Parliament Speaker Mohammad Bagher Ghalibaf. Despite covering core issues—nuclear programme, sanctions relief, frozen assets and control of the Strait of Hormuz—the talks concluded without a memorandum, with Vance asserting that Iran “did not accept our terms” and that the U.S. requires a “fundamental commitment” to forego nuclear weapons. President Donald Trump has described the conflict as “very close to being over” and hinted that a second round could resume within days, possibly in Islamabad. However, Pakistan’s Prime Minister Shehbaz Sharif is currently on a four‑day tour of Saudi Arabia, Qatar and Turkey to rally regional backing, making a rapid return to Islamabad uncertain. U.S. officials have offered an “in‑principle” agreement to extend the ceasefire, yet a Reuters‑cited source confirmed that Washington has not formally committed to an extension. Meanwhile, Turkish President Recep Tayyip Erdogan expressed optimism, stating that “there can be no negotiating with clenched fists.” Key sticking points remain: Nuclear programme: The United States and Israel demand a complete halt to uranium enrichment, accusing Iran of weaponization despite a lack of public evidence. Iran maintains its enrichment is for civilian use and cites its obligations under the 1970 Non‑Proliferation Treaty. Strait of Hormuz: One‑fifth of global oil and LNG passes through this chokepoint. Since the February strikes, shipping through the strait has dropped by 95 %. Iran permits passage for “non‑hostile” vessels and seeks the right to levy tolls, while the U.S. insists on unrestricted navigation. Lebanon/Hezbollah: Iran demands that Israel cease its offensive against Hezbollah. While Tehran claims the ceasefire covers Lebanon, both the United States and Israel reject this, and Israel continues attacks on Hezbollah positions. Complicating the diplomatic landscape, President Trump announced a naval blockade of Iranian ports, adding pressure on Tehran and potentially hindering any imminent talks. With the ceasefire deadline looming and regional actors issuing mixed signals, the prospects for a renewed U.S.–Iran dialogue hinge on whether Pakistan can secure a consensus among the parties before the window closes.

The report delves into Iran's concerted effort to reshape global perceptions by leveraging a blend of state‑run outlets, social‑media networks, and allied voices to contest the United States' long‑standing narrative advantage. It highlights Tehran's use of targeted messaging, strategic timing, and multilingual content to reach diverse audiences, aiming to undermine U.S. credibility while bolstering its own diplomatic posture. By examining recent campaigns and their reception, the piece underscores a growing propaganda rivalry that reflects broader geopolitical tensions between the two nations.

Lamine Yamal, Barcelona's rising star, has reaffirmed his commitment to winning the UEFA Champions League with the club. A day after their quarterfinal elimination by Atletico Madrid, Yamal expressed his determination on Instagram, stating that he will not give up on his promise to capture the trophy with Barcelona.“We are Barca, and we will be back where we belong,” Yamal said. “My parents taught me that a man’s word always has to be fulfilled … we’ll bring it to Barcelona.” This statement comes after Barcelona's 2-1 win over Atletico Madrid on Tuesday, which wasn't enough to overcome a 2-0 deficit from the first leg.Yamal, who scored one of Barcelona's goals, had similar sentiments after their 2025 semifinals loss to Inter Milan, vowing not to stop until he fulfills his promise. His inspiration, LeBron James, was evident as his Instagram profile featured James holding the NBA trophy in 2016.Barcelona's president-elect, Joan Laporta, criticized the refereeing in both legs against Atletico, calling it “shameful” and “inadmissible.” The club plans to file a formal complaint with UEFA. Despite the setback, Barcelona leads La Liga by nine points over Real Madrid.Coach Hansi Flick emphasized that the young team will learn from their mistakes and improve. With their next match against Celta Vigo, Barcelona aims to bounce back and move forward in their quest for Champions League glory.

President Donald Trump announced on Fox Business that he will dismiss Federal Reserve Chair Jerome Powell should the governor refuse to leave his post when his term concludes on May 15. The statement, made during an interview with Maria Bartiromo, underscored the president’s willingness to act, saying he “has wanted to fire him, but I hate to be controversial… he will be fired.” Legal scholars and policy analysts quickly cautioned that the president’s threat is not grounded in statutory authority. Skanda Amarnath, executive director of the think‑tank Employ America, told Al Jazeera that the administration is already losing a court battle over an attempt to remove Fed Governor Lisa Cook and would likely face the same outcome if it pursued Powell’s removal. The controversy emerges as the Senate Banking Committee prepares to consider Kevin Warsh, Trump’s nominee to succeed Powell. Warsh’s hearing is scheduled for next Tuesday, but his confirmation remains uncertain. North Carolina Senator Thom Tillis has pledged to block the nomination until the ongoing federal criminal probe into Powell’s conduct concludes. If the Senate fails to confirm a new chair, Powell would remain at the helm until a successor is appointed, extending the period of tension between the White House and the central bank. Trump also referenced a separate investigation into a costly Fed building renovation, noting that U.S. Attorney Jeanine Pirro has not indicated any change in the probe’s direction. However, a federal prosecutor later reported that the investigation uncovered no evidence of criminal wrongdoing. Critics argue that Trump’s broader agenda seeks to increase political control over the Fed’s seven‑member board, aiming to install members who share his economic outlook. Currently, the president has appointed three board members, and one seat—held by Governor Stephen Miran—has technically expired, which would need to be vacated for Warsh to join. Powell has framed the investigation as a pretext to undermine the Fed’s independence in setting monetary policy, a charge that resonates with concerns about preserving the central bank’s autonomy amid political pressure. Overall, the standoff highlights a clash between executive ambition and the institutional safeguards designed to keep monetary policy decisions insulated from short‑term political influence.

The SAVE America Act, a sweeping voting law championed by US President Donald Trump, has become a contentious issue in the country's electoral landscape. The bill, which has garnered near-total support from Republicans, aims to enhance election security by imposing stricter documentation standards for proving citizenship when registering to vote and casting a ballot.At its core, the legislation seeks to require voters to provide proof of citizenship, such as a birth certificate or passport, when registering to vote. It also proposes implementing stricter voter identification requirements for individuals casting ballots, whether by mail or in person. The bill's passage is considered a top priority by Trump ahead of the midterm elections in November, which will determine which party controls the Senate and the US House of Representatives.However, critics argue that the bill will lead to widespread voter disenfranchisement, particularly among marginalized communities. They point out that about 11% of eligible voters lack access to birth certificates, while 52% do not have valid passports. This could potentially affect around 21.3 million people, according to a recent study by election-monitoring groups.The legislation has also raised concerns about its impact on women and individuals who have changed their names after marriage or for other reasons. An estimated 69 million women in the US lack easy access to documentation linking their current legal names to those at birth, according to the League of Women Voters, a leading opponent of the bill.The bill's fate remains uncertain, with Republicans needing to change the Senate's longstanding rules to pass the legislation, which currently requires 60 votes. Trump has urged Republican leaders to scrap the filibuster rule, writing on Truth Social in March that they need to 'Kill the Filibuster.' As debate continues in the Senate, major shifts in support appear unlikely, and it remains to be seen whether the bill will ultimately pass.
